连续5个月每天用粗制生棉油喂高产卵率的母鸡,可引起产卵数的显著减少和蛋重的减轻;而且,实验动物的卵巢和输卵管呈现高度的萎缩。对照组母鸡用同量精制棉油每天喂饲,产卵率、蛋重都无明显变化,卵巢、输卵管亦正常。本实验的结果支持临床和流行病学研究的结论:长期摄入粗制生棉油是引起妇女内生殖器损害的原因。
Feeding hens with high egg production rates with crude raw cotton oil for 5 consecutive months each day can cause a significant reduction in the number of eggs laid and a reduction in egg weight; furthermore, the ovarian and fallopian tubes of experimental animals show a high degree of atrophy. The hens in the control group were fed with the same amount of refined cotton oil every day. There was no significant change in egg production rate and egg weight, and the ovaries and fallopian tubes were normal. The results of this experiment support the conclusions of clinical and epidemiological studies: Long-term intake of raw cotton oil is the cause of female genital lesions.
