Abstract

The effects of 0.0021, 0.00126 and 0.00063 mg thiotox per liter and 5.18, 3.11 and 1.56 malathion per liter (1/3, 1/5, and 1/10 fractions of 96-h LC50) on acid, alkaline and glucose-6-phosphatases in liver, brain and gills of Saccobranchus fossilis were studied after 30 days exposure with or without ascorbic acid. These enzyme activities were altered by these pesticides, but lesser alterations were observed when ascorbic acid was given.

摘要

研究了每升0.0021、0.00126和0.00063毫克硫代毒素以及每升5.18、3.11和1.56毫克马拉硫磷（96小时半数致死浓度的1/3、1/5和1/10部分）在有或没有抗坏血酸的情况下暴露30天后，对黄鳝肝脏、大脑和鳃中酸性、碱性和葡萄糖-6-磷酸酶的影响。这些酶的活性被这些农药改变，但在给予抗坏血酸时观察到的变化较小。
