Avaliação das lesões locais de cães envenenados experimentalmente com Bothrops alternatus após diferentes tratamentos / Evaluation of local lesions in dogs experimentally envenomed by Bothrops alternatus after different treatments

RESUMO

The aim of this study was to evaluate the therapeutic action of flunixin meglumine and aqueous extract of Curcuma longa (10 percent) on local lesions caused by bothropic venom, comparing with the specific antivenom. Twelve adult dogs were inoculated in the middle third of the lateral face of the thigh with 0.3mg/kg of venom. The dogs were divided into three groups of four animals and the treatment was done two hours after venom inoculation as follows: Group I- specific antivenom diluted in saline (one dosage sufficient to neutralize the venom), Group II- flunixin meglumine (1.1mg/kg, IM, once a day for five days), Group III- topical application of aqueous extract of C. longa (10 percent) (three times a day for five days). Necrosis was observed in all dogs of groups I and II, and in two dogs of group III. Edema and hemorrhagic halo were observed in all dogs. Better recovery of lesions was observed in dogs of group I and III. The results denote a satisfactory effect of C. longa on treatment of local lesions caused by bothropic venom in dogs.
