摘要: 本研究以毒蕈碱型乙酰胆碱受体抑制剂阿托品在离体情况下作用于中国仓鼠V79细胞,通过分析V79细胞晚末期和早G1 期细胞核与细胞质构型、双核细胞频率,探讨了阿托品对哺乳动物离体细胞正常有丝分裂过程的影响。结果发现,阿托品使V79细胞的晚末期—早G1 期细胞核和细胞质分裂构型发生显著变化、双核细胞的频率显著提高,提示阿托品可能通过M型胆碱受体阻断过程而对哺乳动物有丝分裂真实性产生影响。胆碱受体的功能异常可能为非整倍体发生的诱因之一。

Abstract: V79 Chinese hamster cells were treated in vit ro by at ropine sulfate , which is an antagonist to cholinergic receptors and inhibitor of muscarinic receptor. The alteration of late telophase2early G1 configuration induced by at ropine were determined by analyzing present or lack of a cytokinesis furrow in late telophase and very early G1 cells , The abnormal cytokinesis were investigated for the f requency of binuclear cells in interphase cells.The tested chemical disturbed mitotic coordination and induced significantly high f requency of binuclear cells.The result indicated that at ropine is able to inhibit mammal mitosis by blocking the function of cholinergic receptor. The malfunction of cholinergic receptors may be a mechanism of aneuploid induction.
