过去在防老剂D对大鼠致癌性的实验研究中,证明了实验动物比单用麻油灌胃的对照动物有较多的胃和阑肠溃疡出血,并且出现了对照动物所没有的肺癌、肾癌、胰腺癌和前列腺癌等。结果提示了防老剂D有一定的毒性和致癌性。为了判断它的危害及可能的预防,我们将该工业品加以精制(简称精制D防),用纯系Wistar大鼠检查其毒性及致癌性。 In the past, experimental studies on the carcinogenicity of antioxidant D in rats have demonstrated that experimental animals have more stomach and saliva ulcer bleeding than control animals fed sesame oil alone, and there are lung cancer and kidneys that control animals do not have. Cancer, pancreatic cancer, and prostate cancer. The results suggest that antioxidant D has certain toxicity and carcinogenicity. In order to judge its hazards and possible prevention, we refined the industrial product (abbreviated as “D”) and examined its toxicity and carcinogenicity with pure Wistar rats.
