Abstract

The effect of anesthetic drugs on the localization of adult worms in albino mice was compared. The animals with 56 days of infection were anesthetized with pentobarbital sodium, ether or chlorophorm. Perfusion was carried out immediately after, recovering the worms and classifying them in relation to their localization on the liver or portal vein and the mesenteric veins. Our results showed that pentobarbital sodium produced a greater displacement of the worms to the liver (89%) than ether (76%) and chlorophorm (34%) did, when compared to the control group (22%). The difference between pentobarbital sodium and ether was significant (p < 0.05). We suggest that anesthetic drugs may not be used in studies on the distribution of adult worms in several hosts.<br>Comparou-se o efeito de drogas anestésicas na localização de vermes adultos em camundongos albinos. Com 56 dias de infecção os animais foram anestesiados com pentobarbital sódico, éter ou clorofórmio. Imediatamente realizou-se a perfusão, sendo os vermes recolhidos e classificados quanto à localização em fígado ou veia porta e nos vasos mesentéricos. Nossos resultados demonstraram que o pentobarbital sódico produziu maior deslocamento dos vermes para o fígado (89%) do que o éter (76%) e o clorofórmio (34%) quando comparados com o grupo controle (22%). As diferenças para o pentobarbital sódico e o éter foram significativas (P < 0,05). Sugerimos que os anestésicos não sejam utilizados nos estudos sobre a distribuição de vermes adultos nos hospedeiros
