鲤鱼（体重约１６克）腹腔注射乙酸棉酚０，７３，５４，１００，２００，４００ｍｇ／ｋｇ体重，经四天（９６小时）后，死亡率分别是０，０，２０％，７０％，９０％，１００％。９６，小时的半数致死剂量是６３．６ｍｇ／ｋｇ体重。注射剂量高于５４ｍｇ／ｋｇ体重时，发生腹腔红肿、体壁溃烂，甚至死亡。实验结果说明虽然棉籽水平的棉酚不引起鲤鱼的任何可见的中毒症状，但是腹腔注射大剂量棉酚可引起与哺乳类相似的中毒症状。 Carp (weighing about 16 grams) were injected intraperitoneally with 0, 73, 54, 100, 200, 400 mg / kg acetaminophen and the mortality rates were 0, 0, 20%, 70% after four days (96 hours) 90%, 100%. 96 hours, the median lethal dose is 63.6mg / kg body weight. Injection dose higher than 54mg / kg body weight, the occurrence of abdominal peritoneal swelling, body wall ulceration, and even death. The experimental results indicate that while gossypol at cottonseed level does not cause any visible signs of carp poisoning, intraperitoneal injections of high doses of gossypol can cause symptoms similar to those in mammals.
