Abstract

The effects of 1.5 ppm of mercuric chloride (LC50/48 hr) on some enzymes and organic substances of liver tissue of Sarotherodon mossambicus were studied. Significant decreases in the activities of succinate dehydrogenases, lactate dehydrogenases, glucose-6-phosphate dehydrogenase, alkaline phosphatase, and acid phosphatase and in the levels of organic substances like total anthrone-positive substances, glycogen, and total ninhydrin-positive substances were observed. The results indicate impaired oxidative and transphosphorylative activities and utilization of carbohydrates during acute mercury toxicosis in fish.

摘要

研究了1.5 ppm氯化汞（48小时半数致死浓度）对莫桑比克罗非鱼肝脏组织中某些酶和有机物质的影响。观察到琥珀酸脱氢酶、乳酸脱氢酶、葡萄糖-6-磷酸脱氢酶、碱性磷酸酶和酸性磷酸酶的活性以及总蒽酮阳性物质、糖原和总茚三酮阳性物质等有机物质的水平显著下降。结果表明，鱼类急性汞中毒期间氧化和转磷酸化活性以及碳水化合物的利用受到损害。
