RESUMO

RESUMO: Esse estudo objetivou avaliar os efeitos da Creolina® quando administrada por diferentes vias de acesso em ratos experimentalmente envenenados pela peçonha de Bothrops jararaca. Em ratas Wistar fêmeas foi inoculada a peçonha botrópica por via intramuscular, e em seguida as ratas foram tratadas com Creolina® (administrada oralmente, topicamente e intramuscularmente) ou a mistura de veneno + Creolina®. Os animais que receberam a Creolina®, além do veneno, por via oral, tópica e muscular desenvolveram a sintomatologia local e achados laboratoriais semelhantes ao grupo que recebeu apenas o veneno. De forma controversa, os animais inoculados com o veneno misturado a Creolina® não apresentaram sinais característicos da ação local do veneno (necrose, hemorragia) e apresentaram parâmetros hematológicos dentro da normalidade para espécie. Esses resultados sugerem que a Creolina® apresentou efeito antiofídico apenas quando misturada ao veneno e administrada intramuscularmente.ABSTRACT: This study aimed to evaluate the effects of Creolin® when administered by different pathways in rats experimentally poisoned with Bothrops jararaca venom. In female Wistar rats, the Bothropic venom was inoculated intramuscularly, and then the rats were either treated with Creolin® (administered orally, topically, or intramuscularly), or with amixture of venom + Creolin® intramuscularly. Animals that received Creolin®, apart from the venom, by oral, topical, or intramuscular routes developed local symptoms and showed laboratory findings similar to those animals that received only the venom. Conversely, animals inoculated with the venom incubated with Creolin® showed no signs of local venom toxicity (necrosis or hemorrhage) and displayed hematological parameters within the normal range for the species. These results suggest that Creolin® exhibited an antiophidian effect only when it is mixed with the venom and administered intramuscularly.
