摘要: 本文报道以荧光原位杂交技术(FISH) 及抗着丝粒抗体间接免疫荧光染色(CREST 染色) 两种技术检测了化合物甲基丙烯酸环氧丙酯( GMA) 诱发微核的着丝粒信号比例,从而判断GMA 的非整倍体诱发效应。结果表明,GMA 诱发的微核约40. 9 - 5715 %为FISH 阳性,说明其具有一定的非整倍体毒性,但CREST 阳性仅为1710 - 2411 % ,说明其对着丝粒蛋白有较强的损害作用。同时,染色体中期相分析表明,GMA 的染色体断裂作用较强,并且染色体损伤主要集中在着丝粒区域。

Abstract: In this research Fluorescence in situ hybridization ( FISH) and antikinetochore antibodies (CREST Syndrome serum) were used in determining the effect of inducing aneuploid of GMA. The two techniques mainly detected the proportion of cent ric signals in micronuclei induced by GMA. The result s showed that FISH positive ratio of GMA was 40. 9 - 51. 5 % , but for CREST2staining it was only 17. 0 - 24. 1 %. It indicated that GMA was a suspected spindle poison and could damage the cent ric protein. The metaphase analysis demonst rated that GMA had significantly clastogenic effect , which mostly happened in cent romere region.
