摘要: 目的:在离体条件下,通过猪脑微管蛋白的聚合和解聚合反应,分析两种乙酰胆碱受体抑制剂—阿托品和筒箭毒碱对微管蛋白聚合的影响。方法:将受试物加入微管蛋白聚合/ 解聚合反应体系中,于37 ℃、350 nm 下检测反应体系吸光值的变化。结果:阿托品和筒箭毒碱均使反应体系吸光值显著下降,提示它们对微管蛋白聚合具有明显的抑制效应。结论:受试化合物可能通过影响微管蛋白聚合来影响有丝分裂进而引发非整倍体。

关键词: 阿托品, 筒箭毒碱:微管蛋白聚合, 非整倍体

Abstract: Purpose : Two kinds of antagonist s to cholinergic receptors , at ropine sulfate and d2tubocurarine , were analyzed for their effect s on porcine tubulin polymerization. Methods : Two chemicals were added into the tubulin polymerization/ depolymerization system and the changes of absorption values at value decreased significantly at the reaction solution. The results indicated that 350 nm and 37 ℃were recorded. Results : The chemicals made the absorption value decreased significantly at the reaction solution. The result s indicated that the chemicals st rongly inhibit the polymerization of tubulin. Conclusion : The tested chemicals interrupt the mitosis by tubulin polymerization and may induce aneuploidy by the pathway.

Key words: at ropine, d2tubocurarine, tubulin polymerization, aneuploidy
