毛发是法医学实验室的常见检材,目前作个人识别的主要依据是测定血型。尽管两份毛发血型相同时不能断定该毛发就是某一人的,但血型不相同时可作否定的结论。据此可缩小侦查范围,有助于准确判断案情真相。因此毛发的血型鉴定在法医学实践中有极其重要的意义。自从Landsteiner发现ABO血型后,其他学者又相继发现这类抗原存在于人体体液,大多数组织细胞及精子里。矢田(1966)作毛发血型测定上获得良好成绩。千叶(1980)证明毛发的皮质部存有血型物质。
Hair is a common forensic laboratory samples, the current main basis for personal identification is the determination of blood type. Although the two hairs are of the same blood type, the hairs can not be judged as one person, but different blood types can be used as a negative conclusion. This can narrow the scope of the investigation, help to accurately determine the truth of the case. Therefore, the identification of the blood type of forensic medicine has an extremely important significance. Since Landsteiner discovered the ABO blood group, other scholars have found that such antigens exist in human body fluids, most of the tissue cells and sperm. Yada (1966) made good results on hair type determination. Chiba (1980) proved that the cortex of the hair contains blood type substances.
