propolis (bee glue) on acute inflammatory animal models.

The anti-inflammatory effects of ethanol (EEP) and water (WSD) extracts in ICR
mice and Wistar rats were analyzed. Both WSD and EEP exhibited significant
anti-inflammatory effects in animal models with respect to thoracic capillary
vessel leakage in mice, carrageenan-induced oedema, carrageenan-induced
pleurisy, acute lung damage in rats. The mechanisms for the anti-inflammatory
effects probably involve decreasing prostaglandin-E(2) (PGE(2)) and nitric
oxide (NO) levels. In rats with Freund's complete adjuvant (FCA) induced
arthritis, propolis extracts significantly inhibited the increase of
interleukin-6 (IL-6) in inflamed tissues, but had no significant effect on
levels of interleukin-2 (IL-2) and interferon-gamma (IFN-gamma). The results
are consistent with the interpretation that EEP and WSD may exert these effects
by inhibiting the activation and differentiation of mononuclear macrophages.

The xanthine oxidase (XOD) inhibitory activity of propolis from China and
Brazil was measured. The propolis from both place were seen to have XOD
inhibitory activity. However, a stronger tendency was shown in the propolis
from China. The compounds in each the propolis were measured quantitatively. A
great deal of chrysin, galangin, and caffeic acid phenetyl ester were found in
the propolis from China, an abundance of p-coumaric acid and artepillin C in
the propolis from Brazil. Therefore it was revealed that the propolis compounds
are very different depending on their place of origin. The XOD inhibitory
activity of these five compounds was measured. Caffeic acid phenetyl ester had
the strongest activity, with chrysin and galangin next; p-coumaric acid and
artepillin C showed weak XOD inhibitory activity. We evaluated the hypouricemic
effect of propolis from China on hyperuricemia induced by the uricase
inhibitor, oxonic acid (500 mg/kg p.o., 1 h before the test drugs), and
measured plasma uric acid values in rats. Oral propolis had a hypouricemic
effect 2 h after its administration to oxonate-pretreated rats. These results
suggested that a continuous intake of propolis may be effective for the prevention
and the treatment of gout and hyperuricemia.

propolis extract.

Two ethanolic propolis extracts (EPE) with and without the caffeic acid
phenethyl ester (CAPE), CAPE and galangin (major components of propolis) were
investigated for anti-inflammatory activity in rats using carrageenin foot
oedema, carrageenin pleurisy and adjuvant arthritis. In our experiments, EPE
with CAPE and CAPE alone significantly inhibited carrageenin oedema,
carrageenin pleurisy and adjuvant arthritis. In contrast EPE without CAPE and
galangin did not exhibit anti-inflammatory effects in acute and chronic
inflammation. These results suggest that the anti-inflammatory activity of
propolis is due to CAPE.

Caffeic acid phenethyl ester, an inhibitor of nuclear factor-kappaB,

Caffeic acid phenethyl ester (CAPE) is an anti-inflammatory component of
propolis (honeybee resin). CAPE is reportedly a specific inhibitor of nuclear
factor-kappaB (NF-kappaB). The aims of our study were 1) to evaluate the effect
of CAPE on cytokine production, NF-kappaB, and apoptosis in two cell lines; 2)
to assess the effect of CAPE on NF-kappaB in rats with
peptidoglycan-polysaccharide (PG-PS)-induced colitis; and 3) to evaluate the
efficacy of CAPE against this colitis. In vitro experiments used rat macrophage
(NR8383) and colonic epithelial cell (SW620) lines. NF-kappaB was evaluated by
electrophoretic mobility shift assay. Cytokines and apoptosis were measured by
enzyme-linked immunosorbent assay. Colitis was induced by intramural injections
of PG-PS into the distal colon. CAPE (30 mg/kg) or vehicle was administered
once daily to rats by intraperitoneal injection, for 1 week. Various
macroscopic and biochemical indices were measured on day 21. CAPE (30
microg/ml) significantly inhibited NF-kappaB and TNF-alpha production in the
macrophage cell line. In macrophages, CAPE significantly increased DNA
fragmentation. CAPE exhibited generally similar effects in the colonic
epithelial cell line. CAPE treatment reduced the mean level of colonic
NF-kappaB in rats. CAPE also induced a significant reduction in gross colonic
injury. Moreover, colonic cytokine levels (TNF-alpha and IL-1beta) were
significantly reduced in CAPE-treated rats. In summary, CAPE inhibits
NF-kappaB, causes a reduction of pro-inflammatory cytokine production, and
induces apoptosis in macrophages. These mechanisms likely contributed to the
attenuation of PG-PS-induced colitis by CAPE.

The effects of ethanolic extract (EEP) of propolis on chronic inflammation were
evaluated using rat adjuvant arthritis. In the chronic inflammatory animal
model, the arthritis index was suppressed by EEP treatments (50 mg/kg/day and
100 mg/kg/day, p.o.). Moreover, physical weakness, induced by the chronic
disease state, was dose-dependently improved in the EEP-treated groups. Its
analgesic effect, assessed using the tail-flick test, was comparable to
prednisolone (2.5 mg/kg/day, p.o.) and acetyl salicylic acid (100 mg/kg/day,
p.o.). In carrageenan rat hind paw edema, which was conducted to test the
effects of subfractions of EEP, the petroleum ether sub-fraction (100 mg/kg,
p.o.) showed an inhibitory effect on the paw edema whereas EEP (200 mg/kg,
p.o.) showed a significant anti-inflammatory effect at 3 and 4 hrs after
carrageenan injection. From these results, we conclude that the ethanolic
extract of propolis had a profound anti-inflammatory effects on both chronic
and acute inflammations.

The use of aqueous propolis extract against radiation-induced damage.

and Technology, Nasr City, Cairo, Egypt.
Whole body exposure to gamma radiation has been experimentally shown to
exaggerate inflammatory responses and to enhance the release of mediators. A
thirteen per cent aqueous extract of propolis (bee glue) was previously shown
to have potent antiinflammatory activity. The present study was carried out to
show whether the extract could influence the exaggerated inflammatory response
in irradiated animals. Rats were exposed to acute (2 and 6 Gy) &
fractionated (1 Gy/week) doses of gamma ionizing radiation. Treatment with the
aqueous extract orally (5 ml/kg) before and after radiation exposure markedly
reduced the exaggerated paw oedema response to carrageenan. In the acute phase
of adjuvant-induced arthritis, exposure to ionizing radiation caused an
increase in serum acid phosphatase level. Malondialdehyde concentration in
plasma and superoxide dismutase activity in blood significantly increased. Treatment
with aqueous propolis extract prior to irradiation reduced malondialdehyde
concentration in plasma and normalized the serum acid phosphatase level. The
extract stimulated the release of superoxide dismutase enzyme. Aqueous propolis
extract could possibly be of therapeutic value in protecting against
inflammatory responses induced by gamma radiation.

Mechanisms involved in the antiinflammatory effect of propolis extract.

Propolis is a natural product produced by the honey bee. The extract contains
amino acids, flavanoids, terpenes and cinnamic acid derivatives. In various in
vitro models propolis extract was shown to inhibit platelet aggregation and to
inhibit eicosanoid synthesis, suggesting that it might have potent
antiinflammatory properties. A 13% aqueous extract was tested orally in three
dose levels (1, 5 and 10 ml/kg) on the carrageenan rat paw oedema model and on
adjuvant-induced arthritis in rats. In both models, the extract showed potent
dose-related antiinflammatory activity, which compared well with that of
diclofenac (as a reference standard). The extract was then tested on an
isolated sensitized guinea pig lung preparation to study its effect on the
release of prostaglandins, leukotrienes and histamine. It is concluded that
propolis extract has potent antiinflammatory properties in vivo. Its activity
can be well correlated with its effects on the release of various mediators of
inflammation.
