广州地区中国人群ESD表型分布和血痕EsD分型的研究

The Studies on the Distribution of EsD Phenotypes of Chinese Population in Guangzhou Area and EsD Phenotyping in Bloodstains

1973年 Hopkinson 等首先发现人类红细胞酯酶 D(esferase D,简称 EsD)具有遗传多态性,用普通琼脂糖凝胶电泳可以将人群分为 EsD 1-1,2-1,2-2三型。此后,其他学者相继发现了一些较为少见的表现型 EsD3-1,EsD4-1,4-2,

It was presented that the results of EsD typing of Chinese population in Guangzhou area using agarose gel eleetrophoresis.Among 600 unrelat- ed healthy individuals tested,the numbers of EsD 1-1,EsD 2-1 and EsD 2-2 types were 163(27%),303(50.5%)and 135(22.5%),respectively, The gene frequencies of EsD^1 and EsD^2 were 0.5225 and 0.4775.It was consistent with Hardy-Weinberg equilibrium.The period of storage of bloodstains which could be typed correctly lasted 2 weeks from May through July in Guongzhou.The blood samples which were left in room condition and decaied naturally could be typed for 9 days.
