HLA 及其在法医学上的应用

HLA 是迄今人类最复杂的遗传多态性系统,其在法医学上的应用,包括亲子鉴定和个人识别的重要性日益被认识。作者等对血痕、血清和唾液的 HLA 测定的研究结果证明:(1)血痕中存在较强的抗补体作用。应用淋巴细胞毒抑制试验测定血痕的 HLA 时,增加补体用量可使测定的正确率达100%,经90天的血痕仍能完全正确检出 HLA 型。(2)血清的 HLA 测定是可行的,这对远道送检血清及尸体血清测定 HLA 有一定价值。(3)唾液中有可溶性 HLA 抗原存在。

THE HLA ANTIGENS AND ITS APPLICATION IN FORENSIC MEDICINE

Since the HLA system is one of the most complex human genetic polym- orphisms,its application in forensic medicine included disputed paternity and criminal identification,have been fairly recognized. The present paper reported the results of our study about the HLA typing in human blood stain,serum and saliva,it was concluded that:(1).The existed strong anti-complementary activity in human blood stain when the amount of complement used in microlym-phocytotoxicity inhibition test(MLIT) was incresed to 10μl,it was found that the results of HLA-All,-B 5 typing in bloodstains were all correct,and the detectable period was at least 90 days; (2).The soluble HLA-A antigens in human serum could reliable detected with MLIT;(3).The soluble HLA-A antigens were also present in the human siliva.
