Groups 1, 2 and 3 were treated with DEC, tetramisole and chlorpromazine respectively, while Group 4 served as infected control. Longevity of microi lariae and dif erential leucocyte counts were recorded till the disappearance of microi lariae from peripheral blood. Glucose-6-phosphatase and succinate dehydrogenase enzymes were localized in the microi lariae recovered from normal and treated rats.Results: The microi lariae survived for 48 days in untreated rats while survival was reduced to 15, 21 and 27 days after treatment with DEC, tetramisole and chlorpromazine, respectively. Eosinophils and neutrophils increased during 2nd and 3rd weeks, whereas the lymphocytes increased during 4-7 weeks. DEC treatment resulted in slight decrease in the localization of succinate dehydrogenase but not in glucose-6-phosphatase. Tetramisole and chlorpromazine treatment did not show any appreciable change in the localization of both the above enzymes. Conclusions: DEC proved the most ef ective drug which cleared the microi laraemia within 15 days and reduced the activity of succinate dehydrogenase to some extent followed by tetramisole and chlorpromazine which took more time for the clearance of microi lariae and had no ef ect on the localization of both glucose-6-phosphatase and succinate dehydrogenase.展开更多
