Exposure of fish over 96 h to 40 and 80% of LC(50) (24 h) of aqueous latex extracts of Euphorbia royleana and Jatropha gossypifolia of family Euphorbiaceae significantly altered the level of total protein, total free amino acids, nucleic acids, pyruvate, lactate, glycogen and as well as protease activity also in muscle, liver and gonadal tissue of the fish Channa punctatus. The alterations in all the biochemical parameters were significantly dose-dependent. Withdrawal study also shows that there is a partial recovery in the levels of glycogen, pyruvate, lactate and nucleic acids, but nearly complete recovery in total protein, total free amino acids level and protease activity in all the three tissues of the fish after the 7th day of the withdrawal of treatment, which supports the view that the plant product is safer in use as pesticides for control of common weed fishes in culture ponds.

一品红大戟和麻风树的胶乳引起的淡水鱼类月季的生化变化。

鱼在大戟科的大戟科和大叶麻风树的含水乳胶提取物在96小时内暴露于40％和LC（50）（24小时）的LC（50）（80％）时，显着改变了总蛋白质，总游离氨基酸，核酸，丙酮酸的水平鱼Channa punctatus的肌肉，肝脏和性腺组织中的乳酸，糖原和蛋白酶活性。所有生化参数的改变均显着剂量依赖性。戒断研究还显示，第七天后，鱼的所有三个组织中糖原，丙酮酸，乳酸和核酸的水平都有部分恢复，但总蛋白，总游离氨基酸水平和蛋白酶活性几乎完全恢复。停药当天，
