用Y染色体特异性探针作斑点印迹法检测人血痕的性别

Differentiation of sex origin of bloodstains by Dot hybridization with Y-chromosome-specific probe

血痕的性别检查是法医学检案中一个重要内容。过去常用的方法是检查血痕里残存有核细胞中的x和y小体，也有试图测定血痕中性激素(主要是睾丸酮)含量的办法来达到鉴定性别的目的。但都因方法比较繁琐且结果不大可靠，或男女性别判断的界线不够清楚，或受澎响的因素太多而不能令人满意。

The results of differenting sex origin of bloodstains and amniotic fluids by Dot hyhridization and Y chromosome-specific probe(3.5kb)were presented.It was shown that this method was possessed of evera advantages,such as exactitude,simplicity,speediness,and so on.
