ABSTRACT

O efeito do veneno de abelha foi avaliado na artrite induzida por antígeno, em coelhos. O veneno de abelha foi ministrado 7 dias antes da indução da artrite, por via subcutânea, nas doses de 1,5; 3,0 e 6,0 mg/Kg/dia. O líquido sinovial foi coletado, para avaliação do número total e diferencial de células; permeabilidade vascular; determinação de prostaglandina E2 e metabólitos de óxido nítrico. A influência de glicocorticóides endógenos foi investigada com metopirona e RU 38 486, em animais que receberam veneno de abelha (1,5 mg/Kg/dia). O pré-tratamento com veneno de abelha (1,5 mg/Kg/dia) reduziu o influxo de leucócitos para a articulação inflamada, assim como os níveis de prostaglandina E2. Esse efeito não foi observado nos animais que receberam metopirona. O RU 38 486 não alterou a atividade antiinflamatória do veneno de abelha.The effect of bee venom was evaluated on antigen induced arthritis, in rabbits. Bee venom was administrated subcutaneously, 7 days before arthritis was induced, in different doses: 1,5; 3,0 and 6,0 g/Kg/day. Total and differential leucocyte migration, protein leakage, intraarticular concentration of prostaglandina E2 and nitric oxide metabolites were quantified in sinovial fluid. The influence of endogenous glucocorticoids was investigated with metyrapone and RU 38 486, in animals treated with bee venom (1,5g/Kg/day). Pre-treatment with bee venom (1,5g/Kg/day) were effective in reducing leucocyte afflux, compared with control animals. Prostaglandin E2 levels were also significantly reduced in this group. This effect was not observed in animals treated with metyrapone. The anti-inflammatory activity of bee venom was not affected by RU 38 486...
