This systematic review aimed to analyze the scientific production concerning the
use of products in the treatment of wounds, published by REBEn from 1970 to
2003. We consulted all numbers of the journal published in the period,
identifying 41 articles of interest. After an appraisal reading we included 11
papers in the sample. We identified a larger publication in the decade of 1990,
prevailing authors of the attendance area, almost-experimental plan and
experience repor. The studied products were papain, propolis, sugar,

Antimicrobial activity of flavonoids.
Cushnie TP, Lamb AJ.
Flavonoids are ubiquitous in photosynthesising cells and are commonly found in
fruit, vegetables, nuts, seeds, stems, flowers, tea, wine, propolis and honey.
For centuries, preparations containing these compounds as the principal
physiologically active constituents have been used to treat human diseases.
Increasingly, this class of natural products is becoming the subject of
anti-infective research, and many groups have isolated and identified the
structures of flavonoids possessing antifungal, antiviral and antibacterial
activity. Moreover, several groups have demonstrated synergy between active
flavonoids as well as between flavonoids and existing chemotherapeutics.
Reports of activity in the field of antibacterial flavonoid research are widely
conflicting, probably owing to inter- and intra-assay variation in
susceptibility testing. However, several high-quality investigations have
examined the relationship between flavonoid structure and antibacterial
activity and these are in close agreement. In addition, numerous research
groups have sought to elucidate the antibacterial mechanisms of action of
selected flavonoids. The activity of quercetin, for example, has been at least
partially attributed to inhibition of DNA gyrase. It has also been proposed
that sophoraflavone G and (-)-epigallocatechin gallate inhibit cytoplasmic
membrane function, and that licochalcones A and C inhibit energy metabolism.
Other flavonoids whose mechanisms of action have been investigated include
robinetin, myricetin, apigenin, rutin, galangin,
2,4,2'-trihydroxy-5'-methylchalcone and lonchocarpol A. These compounds
represent novel leads, and future studies may allow the development of a
pharmacologically acceptable antimicrobial agent or class of agents.

Acute renal failure induced by a Brazilian variety of propolis.
Li YJ, Lin JL, Yang CW, Yu CC.
Department of Nephrology, Chang Gung Memorial Hospital, Taipei, Taiwan.
Propolis is a resinous substance collected by honeybees and used in hive
construction and maintenance. Cumulative evidence suggests that propolis may
have anti-inflammatory, antibiotic, antioxidant, antihepatotoxic, and antitumor
properties. In addition to topical applications, products containing propolis
have been used increasingly as dietary supplements. Although reports of
allergic reactions are not uncommon, propolis is reputed to be relatively
nontoxic. Its systemic toxicity is rarely reported and hence may be
underestimated. This is the first report of propolis-induced acute renal
failure. A 59-year-old man required hemodialysis for acute renal failure. The
patient had cholangiocarcinoma and had ingested propolis for 2 weeks before
presentation. Renal function improved after propolis withdrawal, deteriorated
again after reexposure, and then returned to a normal level after the second
propolis withdrawal. This case indicates that propolis can induce acute renal
failure and emphasizes the need for vigilance and care when propolis is used as
a medicine or dietary supplement.

Propolis is a natural resinous substance collected by bees from tree exudates
and secretions. Its antimicrobial activity has been investigated and inhibitory action
on Staphylococcus aureus growth was evaluated. The in vitro synergism between
ethanolic extract of propolis (EEP) and antimicrobial drugs by two
susceptibility tests (Kirby and Bauer and E-Test) on 25 S. aureus strains was
evaluated. Petri dishes with sub-inhibitory concentrations of EEP were
incubated with 13 drugs using Kirby and Bauer method and synergism between EEP
and five drugs [choramphenicol (CLO), gentamicin (GEN), netilmicin (NET),
tetracycline (TET), and vancomycin (VAN)] was observed. Nine drugs were assayed
by the E-test method and five of them exhibited a synergism [CLO, GEN, NET,
TET, and clindamycin (CLI)]. The results demonstrated the synergism between EEP
and antimicrobial drugs, especially those agents that interfere on bacterial
protein synthesis.

Detection of galangin-induced cytoplasmic membrane damage in
Staphylococcus aureus by measuring potassium loss.
Cushnie TP, Lamb AJ.
Galangin is one of the active antimicrobial principles of propolis or 'bee
glue' and Helichrysum aureonitens, a perennial herb used by South African
indigenes to treat infection. The effect of this compound and antibacterial
agents with known mechanisms of action upon the cytoplasmic membrane integrity
of Staphylococcus aureus was investigated by comparing potassium loss profiles
from bacterial cell suspensions. Using an agar dilution assay, the minimum
inhibitory concentrations (MICs) of the flavonol galangin, the bacteriostatic
antibiotic novobiocin and the bactericidal antibiotic penicillin G against
Staphylococcus aureus NCTC 6571 were determined as being 50 microg/mL, 62.5
ng/mL and 31.3 ng/mL, respectively. When 5x10(7)cfu/mL Staphylococcus aureus
were suspended in 'potassium-free' media containing 50 microg/mL galangin, a
60-fold decrease in viability was observed after 12 h. Populations of 1x10(9)
cfu/mL Staphylococcus aureus incubated for 12 h in 50 microg/mL galangin lost
21% more potassium than untreated control populations. Novobiocin had no effect
on potassium loss, but populations incubated in 31.3 ng/mL penicillin G
exhibited a 6% increase in potassium loss. This data clearly demonstrates that
galangin causes a significant increase in potassium loss from Staphylococcus
aureus cells, which may be attributed to either direct damage to the
cytoplasmic membrane or indirect damage effected through autolysis/weakening of
the cell wall and consequent osmotic lysis.

Department, University of Messina, Messina, Italy.
The aim of this work was to evaluate the antibacterial effect of plant extracts
as alternative and[sol ]or as active agents supporting antibiotics for treating
Helicobacter pylori infection. The effect of either, ethanolic or aqueous
extracts from 17 plant materials were studied against one H. pylori standard
strain and 11 clinical isolates using a disc diffusion test and by evaluating
the minimum inhibitory concentration (MIC) on solid media. An inhibitory
activity against H. pylori strains was recorded in a large percentage of tested
plants. MIC values of ethanolic extracts were from two to four concentration
steps lower than the aqueous ones. In particular, ethanolic extracts of Cuminum
cyminum L. and Propolis expressed MIC90 values of 0.075 mg/mL. The results show
a significant in vitro effect of plant extracts against H. pylori that could be
considered a valuable support in the treatment of the infection and may
contribute to the development of new and safe agents for inclusion in anti-H.

Austria. martin.imhof@akh.ac.at
OBJECTIVE: To evaluate the efficacy of 5% propolis solution in recurrent
vaginitis. METHOD: Fifty-four patients with recurrent vaginal infections having
undergone at least one cycle of antibiotic treatment were instructed to apply a
5% aqueous propolis solution as a vaginal douche for seven days. Vaginal smears
and specific symptoms were evaluated at baseline and 14 days after treatment.
Long-term well-being was assessed by telephone interview six months after
follow-up. RESULT: At the follow-up, the vaginal smears of 41 patients (75.9%)
had improved. Forty-seven patients (87%) reported reliefs concerning at least
one complaint. Associated improvement of smear and well-being was observed in
36 women (66.7%). After 6 months, 33 patients (61.1%) were satisfied with their
condition without having undergone further treatment. CONCLUSION: Propolis may
have a role as an alternative treatment for chronic vaginal infection.

The role of contact allergy in rosacea has rarely been investigated. In this
retrospective study, 361 out of 76,697 patients tested and documented by the
Information Network of Departments of Dermatology between 1995 and 2002 had
rosacea. Patch tests included standard series and constituents of cosmetics and
topical medicaments. 118/361 had additionally been patch tested with their own
cosmetics/medicaments. Positive reactions occurred to nickel (II) sulfate in
9.3%, fragrance mix in 8.8%, thimerosal in 6.9%, Myroxylon pereirae resin in
5.9%, potassium dichromate in 4.6% and propolis in 2.8%. Whereas rosacea
patients had a significantly higher risk of contact allergy to propolis
compared to the remaining patients, in an age- and sex-adjusted analysis,
contact allergy to nickel was significantly less frequent in this group. For
Lyral, the risk was elevated, albeit not significantly. Only 2/329 patients
were positive to neomycin sulfate and 1/100 to gentamicin sulfate, among the
panel of (topical) antibiotics tested. Among 118 patients tested with their own
products, 3 were tested to metronidazole, 1 reacting positively. Irritant or
doubtful patch test reactions were provoked by various substances (vehicles,
oxidants and preservatives of various creams), which might also be clinically
important, considering the heightened sensitivity of rosaceous skin.

Galangin expresses bactericidal activity against multiple-resistant
bacteria: MRSA, Enterococcus spp. and Pseudomonas aeruginosa.
Pepeljnjak S, Kosalec I.
The antimicrobial activity of three propolis ethanol extracts (EEP) was
examined for various Gram-negative and Gram-positive bacterial species,
including multiple-resistant Staphylococcus aureus, Enterococcus spp. and
Pseudomonas aeruginosa strains. EEP had a good bactericidal activity against
Gram-positive species, and all multiple-resistant bacterial strains tested were
sensitive to EEP. Minimal inhibitory concentrations (MICs) were lower in
samples of higher flavonoid content (from 0.65 to 7.81 mg mL(-1)), indicating
the influence of the concentration of some potent bactericidal compound(s) in
propolis or synergism among some bactericidal compounds. Antimicrobial-guided
separation of flavonoid aglycones (bioassay in situ on thin-layer chromatogram)
showed that galangin (3,5,7-trihydroxyflavone) is one compound in EEP with
bactericidal activity. Galangin was isolated by preparative chromatography.
After determining the quantity present, the MIC against multiple-resistant
bacteria was determined. The MIC of galangin against multiple-resistant
bacterial strains was significantly lower (from 0.16 to 0.44 mg mL(-1), p <
0.05) than that of EEP. The bactericidal activity of galangin against P.
aeruginosa strains was present at 0.17+/-0.05 mg mL(-1).

anti-inflammatory action.
Silva FB, Almeida JM, Sousa SM.
Center of Biological Sciences and Professions of Health, University of Sacred
Heart, Bauru.
The objective of this study was to evaluate the irritant potential of propolis,
Casearia sylvestris, Otosporin and saline solution (control). Twenty-eight male
Wistar rats were selected, anesthetized and four experimental sites were
designed on their backs. Injections of 2% Evans blue were intravenously
administered in the lateral caudal vein and 0.1 ml of the tested solutions was
injected intradermally into the experimental sites. The animals were killed
1/2, 1, 3 and 6 hours after the injection of the solutions. Each piece of skin
containing the lesion was immersed in formamide and incubated at 45 masculine C
for 72 h. After filtration, optical density was measured in a
spectrophotometer. Data were statistically analyzed by a 2-way non-parametric
test. The highest values of extracted dye were observed at 3 hours
characterizing a peak in the inflammatory process. Propolis was the least
irritant solution. The natural medicaments tested in this study may be a
valuable alternative for endodontic treatment.

Mycobacterium tuberculosis (H(37)R(v))-infected guinea-pig model was used to
investigate the effect of water extract of propolis (WEP). After subcutaneous
inoculation of tubercle bacilli, each animal received oral WEP (n=9), isoniazid
(n=5) or saline (n=6) as placebo and were sacrificed 30 days later. Formation
of necrosis was less prominent in the group treated with WEP, but was not
statistically significant (P>0.05). The granuloma formation in the same
group was more prominent than the placebo and isoniazid groups; however, this
finding failed to reach statistical significance by the Kruskal-Wallis test
(P>0.05). These findings suggest that Turkish WEP may have a limited effect
on the development of tuberculosis infection in this guinea-pig model.

Department of Bacteriology, Institute of Microbiology and Immunology, School of
Medicine, University of Belgrade, Dr Subotica 1, 11000 Belgrade, Serbia. stepan@afrodita.rcub.bg.ac.yu
The aim of this study was to investigate antimicrobial properties of ethanolic
extract of 13 propolis (EEP) samples from different regions of Serbia against
39 microorganisms (14 resistant or multiresistant to antibiotics), and to
determine synergistic activity between antimicrobials and propolis.
Antimicrobial activity of propolis samples was evaluated by agar diffusion and
agar dilution method. The synergistic action of propolis with antimicrobial
drugs was assayed by the disc diffusion method on agar containing subinhibitory
concentrations of propolis. Obtained results indicate that EEP, irrespectively
of microbial resistance to antibiotics, showed significant antimicrobial
activities against Gram-positive bacteria (MIC 0.078%-1.25% of EEP) and yeasts
(0.16%-1.25%), while Gram-negative bacteria were less susceptible
(1.25%-->5%). Enterococcus faecalis was the most resistant Gram-positive
bacterium, Salmonella spp. the most resistant Gram-negative bacteria, and
Candida albicans the most resistant yeast. EEP showed synergism with selected
antibiotics, and displayed ability to enhance the activities of antifungals.
The shown antimicrobial potential of propolis alone or in combination with
certain antibiotics and antifungals is of potential medical interest.

Protective role of Egyptian propolis against tumor in mice.
El-khawaga OA, Salem TA, Elshal MF.
Chemistry Department, Faculty of Science, Mansoura University, Mansoura City,
Egypt. elkhawaga70s@mans.edu.eg
BACKGROUND: Propolis has numerous biologic activities including antibiotic,
antifungal, antiviral and anti-inflammatory properties. The present work is
aimed to study the effect of crude Egyptian propolis on tumor in mice induced
by Ehrlich ascitis carcinoma (EAC) cell line. RESULTS: The administration of
propolis (160 mg/kg body weight), by gastric intubation 2 h before the
intraperitoneal injection of EAC, effectively inhibited tumor growth and the proliferation
of EAC. The tumor volume was markedly reduced from 7+/-0.9 ml in EAC-infected
mice to 1.6+/-0.95 ml in propolis-treated mice. Also, the lipid peroxide level
which was 13.3+/-1.24 nmol malodialdehyde (MDA)/mg protein in EAC infected mice
was significantly decreased to 3.3+/-2.1 nmol MDA/mg protein. Reduced
glutathione (GSH) and glutathione S-transferase (GST) concentrations were
markedly increased in propolis-treated mice. This effect was associated with
inhibition of cell cycle progression and induction of apoptosis. Administration
of propolis 2 h before injection of EAC arrested cells in G0/G1 phase and
resulted in a decrease in the viability, DNA, total RNA and protein level of
tumor cells. CONCLUSIONS: Crude Egyptian propolis has a strong inhibitory
activity against tumors. The anti-tumor mechanism may be mediated by preventing
oxidative damage and induction of apoptosis.

Acetone and ethanol extracts of two Bulgarian propolis samples (Bur and Lov)
were investigated by high temperature high resolution gas chromatography
coupled to mass spectrometry (HT-HRGC-MS), and their activity against
Trypanosoma cruzi was evaluated. The ethanol extracts--Et-Bur and
Et-Lov--showed similar composition, with a high content of flavonoids, and
strong inhibitory activity against T. cruzi proliferative epimastigotes, which
were more susceptible than trypomastigotes. In the presence of blood, the
activity of Et-Bur or Et-Lov against trypomastigotes was similar to that of the
standard drug, crystal violet. Both extracts also showed similar and
significant activity against Staphylococcus aureus and Candida albicans, while
being inactive against Escherichia coli. The acetone extract, Ket-Bur, was more
active than Et-Bur against both forms of T. cruzi.

Propolis is one of the few natural remedies that has maintained its popularity
over a long period of time. The pharmacologically active molecules in the
propolis are flavonoids and phenolic acids and their esters. These components
have multiple effects on bacteria, fungi and viruses. In addition, propolis and
its components have anti-inflammatory and immunomodulatory activities.
Moreover, propolis has been shown to lower blood pressure and cholesterol
levels. However, clinical studies to substantiate these claims are required.

Antibiotics are widely used in treatment and prophylaxis of mastitis, but their
antibacterial and therapeutic efficacy continues to decrease. New methods of
prophylaxis of mastitis with the use of vaccines and biological response
modifiers are reviewed. Prophylactic activity of staphylococcal vaccines should
be investigated in the future because of difficulties in successful treatment
of infections caused by these organisms. Vaccination with J5 bacterin (0111:B4)
reduced duration of IMI and local signs of clinical coliform-mastitis. Some
immunomodulators proved to be effective in treatment of mastitis during
lactating period. Promising results were obtained with the use of giseng
saponin, herbal gel, herbal extracts, propolis, lysosubtilin, antibacterial
proteins, and lysozyme dimer especially.

ethanol propolis extract (EPE) and compare it to the inhibitory action of the
standardized antifungal agents nystatin (NYS), clotrimazole (CL), econazole
(EC), and fluconazole (FL). Twelve C. albicans strains collected from
HIV-positive patients with oral candidiasis were tested. The inhibition zones
were measured with a pachimeter and the results are reported as means and
standard deviation (M +/- SD). Data were analyzed statistically by the
non-parametric Kruskal-Wallis test. EPE inhibited all the C. albicans strained
tested. No significant difference was observed between the results obtained
with NYS and EPE, while significant differences were observed between EPE and
other antifungals. The C. albicans strains tested showed resistance to the
remaining antifungal agents. The propolis extract used in this study inhibited
the in vitro growth of C. albicans collected from HIV-seropositive Brazilian
patients, creating/forming inhibition zones like those ones formed by NYS. This
fact suggests that commercial EPE could be an alternative medicine in the
treatment of candidiasis from HIV-positive patients. However, in vivo studies
of the effect of EPE are needed to determine its possible effects on the oral
mucosa.

Antibacterial activity and chemical composition of Turkish propolis.
Keskin N, Hazir S, Baser KH, Kurkcuoglu M.
The antibacterial activities of propolis samples have been examined in vitro,
according to the principles accepted for the determination of a similar
activity of antibiotics with the use of solid and liquid media. It has been
found that propolis extracts showed antibacterial activity through a range of
commonly encountered gram positive cocci (S. aureus, beta hem. Streptococus),
but had weak activity against gram negative bacteria (E. coli, P. aeruginosa).
GC/MS analysis showed that propolis samples contain a variety of chemical
compounds including aromatic compounds, fatty acid esters and sesquiterpenes.

Propolis has numerous biologic activities including antibiotic, antifungal,
antiviral and anti-inflammatory properties. Several components isolated from
propolis have been shown to have anticancer activity. This study demonstrates
that the compound PM-3
(3-[2-dimethyl-8-(3-methyl-2-butenyl)benzopyran]-6-propenoic acid) isolated
from Brazilian propolis markedly inhibits the growth of MCF-7 human breast
cancer cells. This effect was associated with inhibition of cell cycle
progression and induction of apoptosis. Treatment of MCF-7 cells with PM-3
arrested cells in the G1 phase and resulted in a decrease in the protein levels
of cyclin D1 and cyclin E. PM-3 also inhibited the expression of cyclin D1 at
the transcriptional level when examined in cyclin D1 promoter luciferase
assays. Induction of apoptosis by PM-3 occurred within 48 hours after treatment
of MCF-7 cells. The MCF-7 treated cells also displayed a decrease in the level
of the estrogen receptor (ER) protein and inhibition of estrogen response element
(ERE) promoter activity. Therefore, PM-3 merits further investigation with
respect to breast cancer chemoprevention or therapy.

Propolis is a resinous hive product collected by honeybees from various plant
sources. It is extensively used in food, beverage and in folk medicine for
treating various ailments and reported to have broad spectrum of biological
activities. The hepatoprotective activity of propolis and constituents from its
MeOH extract belonging to various classes were tested on D-galactosamine
(D-GalN)/tumor necrosis factor-alpha (TNF-alpha)-induced cell death in primary
cultured mouse hepatocytes. The result indicated that hepatoprotective activity
of alcoholic extract of tropical Brazilian propolis is mainly due to phenolic
compounds including flavonoids. All the four isolated flavonoids possessed
stronger inhibitory activity (IC50, < 25 microM) than silibinin (IC50, 39.6
microM) on TNF-alpha-induced cell death. The labdane-type diterpenes isolated
from the MeOH extract also exhibited significant hepatoprotective activity in
the same experimental model. Moreover, the labdane-type diterpenes and some of
the prenylated phenolic compounds possessed antibacterial activity against
Helicobacter pylori.

Four compounds were isolated from Brazilian propolis. They are identified as:
(1) 3-prenyl-4-hydroxycinnamic acid (PHCA), (2)
2,2-dimethyl-6-carboxyethenyl-2H-1-benzopyrane (DCBEN), (3) 3,5-diprenyl-4-hydroxycinnamic
acid (DHCA), and (4) 2,2-dimethyl-6-carboxyethenyl-8-prenyl-2H-1-benzopyran
(DPB). The
structures of the compounds were determined by MS and NMR techniques. All
compounds were assayed against Trypanosoma cruzi and the bacteria Escherichia
coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus faecalis.
Compounds (1) to (4) were active against T. cruzi. Except (1), all compounds
presented activity against the bacteria tested. When compounds (1)-(3) were
tested in the guinea pig isolated trachea, all induced a relaxant effect
similar to propolis extract.

Detection of antimicrobials in bee products with activity against
viridans streptococci.
Tichy J, Novak J.
Department of Microbiology, University of Alabama at Birmingham, 35294, USA.
OBJECTIVES: Bee products have been studied extensively for their healing
properties and have become part of cosmetic preparations and folk medicine. The
major objective of this study was to examine the presence of antimicrobials in
various bee products. DESIGN: Propolis, honeycomb lids, pollen, honeycombs, and
honey were screened for antimicrobial compounds. Viridans streptococci were
used as indicator strains. Ethanol extracts were applied onto paper disks, dried,
and put on the surface of nutrient agar plates with the overlay containing
viridans streptococci. The plates were then incubated and evaluated the next
day for the presence of inhibition zones. The size of the inhibition zone
represented a quantitative measure of antimicrobial activity in a sample.
Thin-layer chromatography was used for separation of compounds in the samples
and biodetection-an overlay with indicator strain-identified the antimicrobial
compounds by formation of inhibition zones. RESULTS: Ethanol extracts of
propolis and honeycomb lids, as well as honey containing honeycomb lids
contained a mixture of antimicrobial compounds in various amounts. Thin-layer
chromatography experiments with two different solvent systems differing in polarity
suggested that major antimicrobials present in the samples prepared from
honeycomb lids, honeycombs, pollen, and propolis have similar properties. These
active compounds were not extremely hydrophobic. CONCLUSIONS: Extracts from the
tested samples of bee products exhibited antimicrobial properties at various
levels depending on the sample and bacterial species used for testing. Using
chromatographic techniques, we demonstrated similar properties of the active
compounds in various active samples. In conclusion, our results suggest that
honey containing honeycomb lids may be a beneficial food supplement because of
the presence of antibacterial compounds.

18618-000, SP, Botucatu, Brazil.
The behavior of microorganisms towards the antibiotic action of propolis has
been widely investigated. Since reports dealing with seasonal effect on
propolis activity are not available, this assay was carried out aiming to
observe the in vitro antimicrobial activity of propolis, collected during the
four seasons, on bacterial strains isolated from human infections. Dilution of
ethanolic extract of propolis (EEP) in agar was the method performed, with serial
concentrations ranging from 0.4 to 14.0% (% v/v). The behavior of some bacteria
was analysed according to the incubation period in medium plus propolis, and
the survival curve was plotted. It was verified that the growth of
Gram-positive bacteria is inhibited by low propolis concentrations (0.4%)
whereas Gram-negative bacteria were less susceptible to this substance, the
minimal inhibitory concentration ranging from 4.5 to 8.0%. There was no
significant difference with regards to the seasonal effect on the survival
curve of Staphylococcus aureus and Escherichia coli; after incubation with
propolis, there was an efficient antimicrobial action, mainly towards
Gram-positive bacteria.

In vitro antimicrobial activity of propolis and Arnica
Koo H, Gomes BP, Rosalen PL, Ambrosano GM, Park YK, Cury JA.
Arnica and propolis have been used for thousands of years in folk medicine for
several purposes. They possess several biological activities such as
anti-inflammatory, antifungal, antiviral and tissue regenerative, among others.
Although the antibacterial activity of propolis has already been demonstrated,
very few studies have been done on bacteria of clinical relevance in dentistry.
Also, the antimicrobial activity of Arnica has not been extensively
investigated. Therefore the aim here was to evaluate in vitro the antimicrobial
activity, inhibition of adherence of mutans streptococci and inhibition of
formation of water-insoluble glucan by Arnica and propolis extracts. Arnica

Department of Ophthalmology, Celal Bayar University, Faculty of Medicine,
Manisa, Turkey. fozturk@bayar.edu.tr
PURPOSE: To investigate the effect of propolis, a natural resin produced by
honeybees, in the treatment of alkali-injured rabbit eyes. METHOD: A corneal
alkali burn was induced by applying filter paper immersed in 1 N NaOH on the
central axis of the right corneas of 24 rabbits for 30 s. The animals were
divided into three treatment groups: group 1 (control) was given 0.3%
tobramycin and phosphate-buffered solution; group 2 was treated with antibiotic
coverage and topical 1% ethanolic extract of propolis; group 3 received
antibiotic coverage and topical 1% dexamethasone. The dexamethasone-treated
group was maintained as the positive control. Drugs were instilled 4 times a
day for 7 days. The corneal inflammation was evaluated by calculating the
average inflammatory index obtained from clinical observation of the ciliary
hyperemia, central and peripheral corneal edema at 24 h, 48 h, on day 5 and day
7, before sacrificing the animals. Then, the corneas underwent routine
histological examination. RESULTS: The effects of dexamethasone and propolis on
healing of injured corneas were similar (p>0.05) and significantly better
than controls at 24 h (p<0.01, p< 0.05, respectively), and on day 7
(p<0.05) with respect to the inflammatory index. On histological
observation, inflammatory cell infiltration was lower as compared to control in
both the dexamethasone and propolis groups (p<0.001) and similar with each
other (p>0.05). CONCLUSIONS: Our study shows that propolis has an
anti-inflammatory effect comparable to dexamethasone in chemical corneal
injury. Copyright 2000 S. Karger AG,

Synergism between ethanolic extract of propolis (EEP) and

Ethanolic extract of propolis exerts a strong anti-bacterial activity, in
addition to antifungal, antiviral and antiprotozoal properties. In previous
studies from these laboratories we have demonstrated that the intensity of the
bactericidal activity of EEP is correlated with the virulence of the
mycobacteria tested, and that EEP has a synergistic effect with antibiotics on
growth of staphylococcus aureus. In the present study we investigated whether
the same synergism and correlation exists between EEP and some
anti-tuberculosis drugs on tuberculosis mycobacteria with different degrees of
virulence. Six standard strains and 11 wild strains of mycobacteria were
exposed for 30 days to EEP, with or without streptomycin, rifamycin, isoniazid
or ethambutol. Out of the 17 strains, 8 were resistant to at least two standard
antibiotics, and were considered "multi-resistant strains". The rest
were either susceptible or resistant to only one of the antimycobacterial
drugs. Antagonism was recorded only in one case, when Staphylococcus aureus
were treated with a mixture of EEP and ethambutol, suggesting that a chemical
bond could have been formed between this anti-tuberculosis antibiotic and one
of the active components of the ethanol extract of propolis.

Antibacterial, antifungal and antiviral activity of propolis of
different geographic origin.

Propolis samples from different geographic origins were investigated for their
antibacterial (against Staphylococcus aureus and Escherichia coli), antifungal
(against Candida albicans) and antiviral (against Avian influenza virus)
activities. All samples were active against the fungal and Gram-positive
bacterial test strains, and most showed antiviral activity. The activities of
all samples were similar in spite of the differences in their chemical
composition. In samples from the temperate zone, flavonoids and esters of
phenolic acids are known to be responsible for the above mentioned activities
of bee glue; tropical samples did not contain such substances but showed
similar activities. Obviously, in different samples, different substance
combinations are essential for the biological activity of the bee glue. It
seems that propolis has general pharmacological value as a natural mixture and
not as a source of new powerful antimicrobial, antifungal and antiviral
compounds.

Propolis is a multifunctional material used by bees in the construction and
maintenance of their hives. Use of propolis by humans has a long history,
predated only by the discovery of honey. Use of products containing propolis
have resulted in extensive dermal contact and it is now increasingly being used
a dietary supplement. Unlike many 'natural' remedies, there is a substantive
database on the biological activity and toxicity of propolis indicating it may
have many antibiotic, antifungal, antiviral and antitumour properties, among
other attributes. Although reports of allergic reactions are not uncommon, propolis
is relatively non-toxic, with a no-effect level (NOEL) in a 90-mouse study of
1400 mg/kg body weight/day.

Antimicrobial action of propolis and some of its components: the effects
on growth, membrane potential and motility of bacteria.
Mirzoeva OK, Grishanin RN, Calder PC.
Department of Biochemistry, University of Oxford, United Kingdom.
The effect of the natural bee product propolis on the physiology of
microorganisms was investigated using B. subtilis, E. coli and R. sphaeroides.
An ethanolic extract of propolis had a bactericidal effect caused by the
presence of very active, but labile, ingredients. The exact bactericidal effect
of propolis was species dependent: it was effective against gram-positive and
some gram-negative bacteria. Propolis and some of its cinnamic and flavonoid
components were found to uncouple the energy transducing cytoplasmic membrane
and to inhibit bacterial motility. These effects on the bioenergetic status of
the membrane may contribute to the antimicrobial action of propolis and its
observed synergism with selected antibiotics.

Electron microscopic and microcalorimetric investigations of the
possible mechanism of the antibacterial action of a defined propolis
provenance.
Takaisi-Kikuni NB, Schilcher H.
Department de Microbiologie, Faculte de Pharmacie, Universite de Kinshasa,
Zaire.
Microcalorimetric and electron microscopic studies on the mode of the
antibacterial action of propolis were performed on Streptococcus agalactiae. It
was shown that propolis inhibits bacterial growth by preventing cell division,
thus resulting in the formation of pseudo-multicellular streptococci. In
addition, propolis disorganized the cytoplasm, the cytoplasmic membrane, and
the cell wall, caused a partial bacteriolysis, and inhibited protein synthesis.
It was evident that the mechanism of action of propolis on bacterial cells is
complex and a simple analogy cannot be made to the mode of action of any
classic antibiotics.

Institut fur Botanik und Mikrobiologie, Biochemisches Labor, Technische
Universitat Munchen.
Ethanolic and aqueous extracts of the natural compound PROPOLIS indicate substantial
antiinflammatory functions as well as antibiotic activities in vitro and in
vivo. The exact mode of physiological or biochemical mechanisms responsible for
the medical effects, however, is all but clear. The standardization on the
basis of quantitative determination of prominent components of these extracts
have been substituted recently by simple biochemical model reactions including
photodynamic properties. In this communication we report on the inhibitory
activity of an aqueous extract of propolis on the enzyme dihydrofolate
reductase. This activity may at least partially be due to the content of
caffeic acid, as revealed by HPLC chromatography and comparative activity tests
of representative ingredients of the propolis extract. This result may explain
some of the protective functions of propolis, similar to those shown for
several "non-steroidal antiinflammatory drugs", NSAIDs.

Effect of caffeic acid esters on carcinogen-induced mutagenicity and
human colon adenocarcinoma cell growth.

New York.
Propolis, a honey bee hive product, is thought to exhibit a broad spectrum of
activities including antibiotic, antiviral, anti-inflammatory and tumor growth
inhibition; some of the observed biological activities may be due to caffeic
acid (cinnamic acid) esters that are present in propolis. In the present study
we synthesized three caffeic acid esters, namely methyl caffeate (MC),
phenylethyl caffeate (PEC) and phenylethyl dimethylcaffeate (PEDMC) and tested
them against the 3,2'-dimethyl-4-aminobiphenyl, (DMAB, a colon and mammary
carcinogen)-induced mutagenicity in Salmonella typhimurium strains TA 98 and TA
100. Also, the effect of these agents on the growth of human colon
adenocarcinoma, HT-29 cells and activities of ornithine decarboxylase (ODC) and
protein tyrosine kinase (PTK) was studied. Mutagenicity was induced in
Salmonella typhimurium strains TA 98 and TA 100 plus S9 activation using 5 and
10 micrograms DMAB and antimutagenic activities of 0-150 microM MC, 0-60 microM
PEC and 0-80 microM PEDMC were determined. The results indicate that MC, PEC
and PEDMC were not mutagenic in the Salmonella tester system. DMAB-induced
mutagenicity was significantly inhibited with 150 microM MC, 40-60 microM PEC
and 40-80 microM PEDMC in both tester systems. Treatment of HT-29 colon
adenocarcinoma cells with > 150 microM MC, 30 microM PEC and 20 microM PEDMC
significantly inhibited the cell growth and syntheses of RNA, DNA and protein.
ODC and PTK activities were also inhibited in HT-29 cells treated with
different concentrations of MC, PEC and PEDMC. These results demonstrate that
caffeic acid esters which are present in Propolis possess chemopreventive
properties when tested in short-term assay systems.

Antibacterial properties of propolis (bee glue).
Grange JM, Davey RW.
Department of Microbiology, National Heart & Lung Institute, London.
Propolis (bee glue) was found to have antibacterial activity against a range of
commonly encountered cocci and Gram-positive rods, including the human tubercle
bacillus, but only limited activity against Gram-negative bacilli. These
findings confirm previous reports of antimicrobial properties of this material,
possibly attributable to its high flavonoid content.

[Article in Italian]
Marroni A, Arduini R, Conti S.
Microbiological analysis of the variation in the bacterial flora of the
external auditory canal was carried out during 39 immersion in saturated
solutions. A double blind test on the usefulness of prophylactic and
therapeutic preparations was also carried out. Prophylactics. - 5% Al acetate in
H2O (P1), Boric alcohol (P2), lactic acid in H2O (P3, Domeboro (P4), no
prophylactic (P0). After the immersions, a significant increase in Pseudomonas
Aeruginosa and Candida Albicans (p less than 0,01) was noted in the auricular
bacterial flora. Gram positive bacteria in general were considerably reduced (p
less than 0,01). Gram negative bacteria other than pseudomonas. A (p less than
0,3) and coagulase negative straphylococci (p less than 0,03) did not vary
significantly. Prophylactic preparations P1 and P2 were shown to be
significantly more effective than P3, P4 and P0 in preventing the
symptomatology (p less than 0,01). The most effective therapeutic preparation
was found to be a locally applied gentamycinpolymixin association.

Growth inhibition of bacillus subtilis and composition of various
propolis extracts.
Pepeljnjak S, Jalsenjak I, Maysinger D.
The composition of 31 samples of propolis extract was investigated by using
TLC. Ethanol extract of propolis (EEP) prepared from the various propolis
samples differ mainly in quantities of identified compounds, and not in kind of
components present. According to the inhibitory activity against Bacillus
subtilis, the propolis samples were grouped in three categories. It appears
that the galangin content in a sample is a main constituent, which determines
its antibacterial activity.

The activity of propolis and its combinations with antibiotics against
antibiotic resistant strains of Staphylococcus aureus was studied. It was found
that staphylococcae strains resistant to benzylpenicillin, tetracycline and
erythromycin were mainly sensitive to propolis. It is concluded that there was
synergism in the effect of propolis and antibiotics with respect to antibiotic
resistant strains of Staphylococcus aureus.

[Identification of an antimicrobially active constituent isolated from

[Article in German]
Schneidewind EM, Buge A, Kala H, Metzner J, Zschunke A.
On isolating and identifying antimicrobially active propolis constituents, the
authors detected a substance that must be regarded as a mixture of caffeic acid
esters. The caffeic acid moiety was unequivocally identified by various
chemical and spectroscopic methods. The results obtained from the gas
chromatographic study of the alcohol fraction after hydrolysis of the isolated
compound identify benzyl alcohol, phenyl ethyl alcohol and cinnamic alcohol as
ester components. Furthermore, the mass spectroscopic findings are indicative
of the presence of a caffeic acid pentenyl ester in the mixture. Attempts to
separate this ester mixture by recrystallization and thin-layer chromatography
failed.

[On the antimicrobial activity of propolis and propolis constituents
(author's transl)]
[Article in German]
Metzner J, Bekemeier H, Paintz M, Schneidewind E.
After a survey of the literature on the antimicrobial activity of the bee
product propolis, the authors discuss their own findings as compared to the
chemotherapeutical agents streptomycin, oxytetracycline, chloramphenicol,
nystatin, griseofulvin and sulphamerazine. According to the results obtained by
testing 25 isolated constituents on Bacillus subtilis, Staphylococcus aureus,
Candida albicans and Trichophyton mentagrophytes, the antimicrobial properties
of this mixture of natural substances are mainly attributable to the flavonoids
pinocembrin, galangin, pinobanksin, pinobanksin-3-acetate as well as to the
p-coumaric acid benzyl ester and a caffeic acid ester mixture. None of the
isolated substances was as potent as the antibiotics tested for the purpose of
comparison. The relatively good antimycetic activity of the
5,7-dihydroxyflavanone pinocembrin seems noteworthy. Finally, possible
mechanisms of the antimicrobial action of the flavonoids are discussed.

[Effect of pinocembrin on the course of experimental candida infections

[Article in German]
Metzner J, Schneidewind EM.
Pinocembrin (5,7-dihydroxy-flavanon)--a component of the bee product
propolis--was tested for its in vivo activity against Candida albicans in mice.
It was shown that the intravenous infection of AB-Jena mice with 2.5 X 10(5)
Candida albicans cells was a very suitable model. Despite of treatment with
pinocembrin at daily doses of 100 mg/kg body weight the animals as well as the
controls died between the 6th and 24th day after beginning. On the other hand
the animals treated with 5 mg/kg amphotericin B survived the test-period of 30
days. The question of effectiveness of pinocembrin in vivo should be cleared up
in further pharmacokinetic investigations.

A new selective medium for the isolation of Listeria monocytogenes.
Gronstol H, Aspoy E.
A new selective medium for the isolation of Listeria monocytogenes (Lm), is
described. The medium contained propolis, nalidixic acid, polymyxin B and
rivanol as selective substances. The new medium (propolis-agar) was compared
with two other selective media and one nonselective medium. No inhibitory
effect was found on the 6 strains of Lm tested, and Lm was easily isolated from
a mixture of Lm and contaminating bacteria. The selective effect was better
than for the two other selective media tested.

[Selective effect of propolis in the isolation of Listeria monocytogenes
(author's transl)]
[Article in Norwegian]
Aspoy E.
Propolis is a substance produced by honeybees. It is inhibitory to some
bacteria species, mainly Gram-positive bacteria, but less inhibitory to
Listeria monocytogenes (L.m) than to the other Gram-positive bacteria tested.
In order to obtain selective growth of L.m. from contaminated samples, the
effect of propolis in plating media and broths on various strains of bacteria
was examined. Table I shows the effect of increasing concentrations of propolis
in tryptose-agar (TA). L.m. tolerated higher concentrations of propolis than
Streptococcus viridans and Staphylococcus aureus. L.m. grew well in
tryptosebroth (TB) that contained 0.15 mg propolis pr. ml medium, while
Streptococcus viridans and Streptococcus agalactiae were completely inhibited
as seen in Table II. Table III shows that when serum was added to the agar, the
inhibitory effect was reduced. It can also be seen that Gram-negative bacteria
grew quite well on media that contained 0.19 mg propolis pr. ml. To reduce the
growth of Gram-negative bacteria, nalidixic acid was added to the medium. Table
IV illustrates growth of various species of bacteria in tryptosephosphatebroth (TFB)
with or without propolis and nalidixic acid. Most of the strains tested were
inhibited, but Pseudomonas aeruginosa and to some extent faecal streptococci
were able to grow in the medium that contained the selective substances. As a
conclusion it seems that propolis may be a valuable additive to a medium for
the selective isolation of L.m.

Biological properties and clinical application of propolis. III.
Investigation of the sensitivity of Staphylococci isolated from pathological
cases to ethanol extract of propolis (EEP). Attempts on inducing resistance in
laboratory Staphylococcus strain to EEP.
Scheller S, Tustanowski J, Kurylo B, Paradowski Z, Obuszko Z.
Staphylococci isolated from pathological material exhibited a reduced
sensitivity to ethanol extract of propolis (EEP) in 90% of cases. No
cross-resistance of the staphylococci to EEP and to any commonly used
antibiotics was found. The induction of resistance to EEP in laboratory strain
of Staphylococcus aureus (Oxford 209 P) can be achieved already after serial
passages on nutrient media containing EEP. Culturing Staphylococcus resistant
to EEP in an environment devoid of this compound caused a remission to
sensitivity of the strain investigated.
