Abstract
The effect of malathion (50 mg/kg) and radiation (900R) separately and jointly upon phosphatases and succinic dehydrogenase has been studied in female albino rats. Malathion and radiation when given separately, at the dose levels used in this study, appear to have no effect on acid and alkaline phosphatase of kidney, heart and brain. In preirradiated rats given malathion a significant decrease in phosphatases was observed in kidney and brain tissue after as little as 2 h and the values persisted for up to 24 h. No significant change was observed in heart tissue. At the dose level of 50 mg/kg of malathion, no significant change in succinic dehydrogenase was observed; however, radiation caused a significant increase in succinic dehydrogenase of brain and kidney tissue. In preirradiated rats given malathion the effect appeared to be enhanced in time to a certain degree. One could therefore speculate that simple non-specific stress caused by malathion adds to a similar effort of radiation by reducing phosphatases and enhancing the succinic dehydrogenase enzyme.This publication has 0 references indexed in Scilit:
