关于化学物质诱发动物肿瘤的工作已有大量报道,诱发肿瘤的类型常与致癌物进入机体的途径有关。Toth曾报道通过饮水给Swiss系小鼠摄入偏二甲肼(UDMH),诱发了血管、肺、肾及肝肿瘤。近年又有许多作者报道了UDMH对水生生物、细菌的毒性以及对动物的致突变潜力的测试结果。本文报告采取吸入与经口给药两种途径以UDMH作用于小鼠诱发出肺腺瘤的结果。 There have been numerous reports on the work of chemical substances in inducing animal tumors, and the types of induced tumors are often related to the pathway of carcinogens entering the body. Toth has reported drinking unbalanced dimethylhydrazine (UDMH) in Swiss mice through drinking water, which induces vascular, lung, kidney, and liver tumors. In recent years, many authors have reported the results of UDMH’s toxicity to aquatic organisms, bacteria, and the mutagenic potential of animals. This article reports the results of UDMH-induced murine lung adenomas by two routes of inhalation and oral administration.
