摘要
用聚丙烯酰胺凝胶电泳法测定了广西和湖南省侗族居住区的120例侗族新生儿脐血胎儿血红蛋白中B.subtilis与~Ar比值(~Gr/~Ar值)。显示出119例新生儿的~Gr值(％~Gr)在56—76％之间,均值与标准差为69.4±3.1％;一例新生儿~Gr值高达81.4％,基因图谱分析确定其基因型为~Gr-^(AG)r-~Ar/~Gr-~Ar。
The Gγ to Aγ rateo of fetal hemoglobin in 120 cord blood samples of Dong ethnic new-borns distributed over the Dong Autonomous Regions in Guangxi and Hunan provinces were determined with the method of polyacrylamide gel electrophoresis. The result showed that a case has the high Gγ value of 81.4% while 119 babies have the normal Gγ values of 56 to 76%(69.4f443.1%). The high Gγ case was identified as Gγ-AGγ-Aγ/Gγ-Aγ genotype.
