The carcinogenic effects of cadmium were tested in an animal experiment to check the results of epidemiological studies showing that the incidence of prostatic carcinoma is above average in workers industrially exposed to high cadmium levels. For this purpose 1.9 mg CdCl2 (1.2 mg Cd/kg body weight) was injected into the right ventral prostatic lobe of 12-month-old male inbred rats of the Okamoto-toki strain. Simple hyperplasia was found in 38, atypical hyperplasia in 29, atypical hyperplasia with severe dysplasia in 11 and invasive prostatic carcinoma in 5 of 100 animals 270 days after the injection. Various mechanisms are discussed in connection with the carcinogenic action of cadmium.
在一项动物实验中测试了镉的致癌作用,以检验流行病学研究结果,该结果表明,在工业上接触高镉水平的工人中,前列腺癌的发病率高于平均水平。为此,将1.9毫克氯化镉(1.2毫克镉/千克体重)注入冈本时 strain 12个月大的雄性近交大鼠的右腹侧前列腺叶。注射后270天,在100只动物中,38只出现单纯性增生,29只出现非典型增生,11只出现伴有严重发育异常的非典型增生,5只出现浸润性前列腺癌。讨论了与镉致癌作用相关的各种机制。
