龟壳攀鲈(布洛赫)肝脏中谷胱甘肽谷胱甘肽-S-转移酶系统对工业污染物的解毒作用。

Abstract

The interrelationship of reduced glutathione (GSH) and glutathione-S-transferase in the liver of a freshwater climbing perch Anabas testudineus (Bloch) exposed to common industrial pollutants has been studied. In both short- and long-term treatments there was a concomitant decrease in reduced glutathione profile and an increase in glutathione-S-transferase activity. It may be surmised that the majority of xenobiotics of industrial origin are detoxicated by the glutathione glutathione-S-transferase pathways enabling the fish to survive exposure to the additive and/or synergistic toxicity of mixtures of poisons.

摘要

研究了暴露于常见工业污染物的淡水攀鲈龟壳攀鲈(Anabas testudineus,布洛赫)肝脏中还原型谷胱甘肽(GSH)与谷胱甘肽-S-转移酶的相互关系。在短期和长期处理中,还原型谷胱甘肽水平均随之下降,而谷胱甘肽-S-转移酶活性则增加。可以推测,大多数工业来源的外源性物质通过谷胱甘肽-谷胱甘肽-S-转移酶途径解毒,使鱼类能够在接触毒物混合物的相加和/或协同毒性后存活下来。
