ETHNOPHARMACOLOGICAL RELEVANCE: Bee venom (BV) has been used for the treatment of inflammatory diseases, such as rheumatoid arthritis, and for the relief of pain in traditional oriental medicine.
AIM OF STUDY: The aim of this study was to determine the anti-inflammatory effect of BV on monosodium urate (MSU)-induced gouty arthritis in a mouse model.
MATERIALS AND METHODS: To develop a mouse model of acute gouty arthritis, 4 mg 50 μLof MSU crystal suspension was injected intradermally into the right paw. After MSU crystal injection, we evaluated inflammatory cytokine production in mice of the BV-treated (0.5 and 1 mg kgbody weight) and apamin (APM)-treated (0.5 and 1 mg kgbody weight) groups. The positive control group was administered a colchicine (1 mg kgbody weight) injection with MSU crystals.
RESULTS: BV and APM treatment suppressed inflammatory paw edema in MSU-administered mice. It also exerted anti-inflammatory effects in mice with gouty arthritis by inhibiting proinflammatory cytokine production and inflammasome formation. Interestingly, MSU crystal formation was decreased by BV and APM treatment.
CONCLUSIONS: These results suggest that the APM from BV might be useful for the treatment of gouty arthritis due to its anti-inflammatory activities.
