氯乙烯对人体的致癌作用业已肯定。由于氯乙烯很难从生产环境中完全清除,除应不断改进和研制新的防护设施外。寻求一种能抑制其致癌作用的预防药物也可能是很有效的预防措施。为此目的,我们选用了L-半胱氨酸等几种自由基清除剂配伍,组成复方合剂(下称半胱氨酸合剂),对氯乙烯致瘤作用的预防效果进行了动物实验,结果报告如下: 1 材料与方法 1.1 材料 1.1.1 实验动物选用成年健康Wi
Vinyl chloride on the human carcinogen has been affirmed. Since it is difficult to completely remove vinyl chloride from the production environment, in addition to continuous improvement and development of new protective equipment. It may also be a very effective prophylaxis to find a preventative drug that inhibits its carcinogenic effects. For this purpose, we selected several free-radical scavengers such as L-cysteine to make up a compound mixture (hereinafter referred to as cysteine mixture), and carried out animal experiments on the preventive effect of the carcinogenesis of vinyl chloride. Results The report is as follows: 1 Materials and methods 1.1 Materials 1.1.1 experimental animal selection adult healthy Wi
