青海藏族、土族、撒拉族ABO、Rh、MN、P血型系统分布的研究

DISTRIBUTION OF BLOOD TYPE ABO, RH, MN, P IN TIBETAN TU AND SALA NATIONALITY IN QINGHAI

对青海藏族、土族及撒拉族ABO、Rh、MN、P血型分布的研究结果表明,ABO系统,藏族、土族r>q>P,撒拉族r>p>q;Rh系统,藏族、土族各发现Rh阴性1例(分别占0.74％与0.66％),撒拉族未发现Rh阴性者;三个民族表现型均以CCDee、CcDE较多见;MN系统,均m高于n,但m低于南方各族;P系统,P1频率低于新疆、而高于广西、云南各族。藏、土、撒拉族ABO、Rh、MN、P血型分布与蒙、回、汉族有某些相似之处,说明在民族形成过程中融合了部分其它民族的血统,这与民族史的研究是一致的。

Distribution of blood type ABO,Rh,MN,P inTibetan,Tu and Sala nationality in Qinghai were studied.The results sug- gested that r>q>p in ABO group of Tibetan and Tu nation ality,and r>p>q in Sala were found;one negative Rh case was found separately in Tibetan and Tu (0.74% and 0.66%),while no caes in Sala.There were more CCDee,CcDE to be exp- resed in the three nationality;M more than N is afirmative in MN group,but M is lower than that of south nationality;fre- quency pl is lower than that in Xinaang,and higher than in Guang Xi and Yung Nan.The distrbution of blood tupe ABO, Rh,MN,P in Tlbetan,Tu and it would be in Sala similar to Mongolian,Hui,and Han.It is interpreted that the blood relation- ship have been mixed together other nationality in the course which a nationality is forming,it cininsides with the study of na- tional history.
