Abstract

The effects of mercuric chloride intoxication on the activities of acid and alkaline phosphatases and glucose-6-phosphatase in the hepatopancreas of a freshwater prawn Macrobrachium lamarrei (H. Milne Edwards) were determined after 24, 48, 72, and 96 hr. Mercuric chloride intoxication resulted in elevation of acid phosphatase and inhibition of alkaline phosphatase activities, but glucose-6-phosphatase activity was elevated up to 72 hr after which (i.e., after 96 hr of exposure) inhibition in the enzyme activity was noted at two higher concentrations. Alterations in the activities of these enzymes after mercuric chloride intoxication have been shown to adversely affect the general metabolism of the freshwater prawn.

摘要

在24、48、72和96小时后,测定了氯化汞中毒对淡水虾拉氏沼虾(H. 米尔恩·爱德华兹)肝胰腺中酸性磷酸酶、碱性磷酸酶和葡萄糖-6-磷酸酶活性的影响。氯化汞中毒导致酸性磷酸酶活性升高,碱性磷酸酶活性受到抑制,但葡萄糖-6-磷酸酶活性在72小时前升高,之后(即暴露96小时后)在两个较高浓度下酶活性受到抑制。氯化汞中毒后这些酶活性的改变已被证明会对淡水虾的一般代谢产生不利影响。
