Toxicity tests revealed that the Indian catfish, Heteropneustes fossilis, is highly sensitive to cypermethrin, a synthetic pyrethroid. The LC50 value decreased with increasing exposure time, revealing a time-dependent action of cypermethrin. Biochemical studies confirmed this, showing that the effects on carbohydrate metabolites also revealed a time-dependent response. The probable reasons for the disturbance in the homeostatic mechanisms of carbohydrate metabolism are discussed.
毒性测试表明，印度鲶鱼（Heteropneustes fossilis）对合成拟除虫菊酯氯氰菊酯高度敏感。半数致死浓度（LC50）值随暴露时间增加而降低，表明氯氰菊酯具有时间依赖性作用。生化研究证实了这一点，表明其对碳水化合物代谢物的影响也呈现出时间依赖性反应。文中讨论了碳水化合物代谢稳态机制受到干扰的可能原因。
