摘　　要：用混合凝胶电泳法 ,调查长沙地区 2 34名汉族人群GLOⅠ表型频率分布。发现三种GLOⅠ表型 ,其基因频率为GLOⅠ1 =0 .1 30 3 ,GLOⅠ2 =0 .8697。与不同地区、不同国家和民族相比较。检测不同条件下的血痕标本 ,发现室温下 (2 0～ 30℃ )保存的 2 0例纱布血痕 40d内可全部正确分型 ,低温 0～ 4℃保存的 2 0例纱布血痕至少 1 0 0d也可全部正确分型。日晒。The distribution of GLO Ⅰ phenotypes was studied using mixed agarose starch gel electrophoresis in 234 Chinese Han population in Changsha area. Three GLO Ⅰ phenotypes were detected. The gene frequencies were as follows: GLO Ⅰ 1=0.1303 and GLO Ⅰ 2=0.8697. The phenotype frequencies of GLO Ⅰ were compared not only among the different nationalities but with those reported by other countries. Both the 20 bloodstain samples kept at room temperature for 40 days and the other 20 bloodstain samples kept at 4℃ for at least 100 days could be correctly phenotyped. Two out of 8 watered bloodstains, their GLO Ⅰ 2-1 phenotype was changed to GLO Ⅰ 2-2 . In blind trial, 15 bloodstain samples kept at room temperature for 40 days could be phenotyped correctly.[
