The genetic polymorphism of red cell acid phosphatase (AcP), Esterase D (EsD), 6-phosphogluconate dehydrogenase (6-PGD) and Glutamic pyruvic transaminase (GPT) in eleven ethnic groups of China was studied by starch gel electrophoresis. The results of 2272 tested showed that the gene frequencies of AcPB1 in Dong, Hui, Bai, Tujia, Miao, Yi, Tibetan, Man, Yao,(More)
Isoelectric focusing (IEF) followed by immunofixation in thin layer polyacrylamide gels (pH4-6) was used to analyse the Gc subtypes of 1841 individuals from nine Han geographically distributed populations in China. The Gc1F gene frequencies in these Han subpopulations from Lanzhou, Huhhot, Harbin, Xi'an, Zhengzhou, Chengdu, Guiyang, Zhangzhou and Harras in(More)
The distribution of 19 red cell's antigens of 8 blood group systems in Han ethnic group in Fujian province, China was investigated. The gene and haloptype frequencies were as follows: p = 0.1936, q = 0.1766, r = 0.6298; p1 = 0.1427; Dia = 0.2830; m = 0.5695, n = 0.4305, S = 0.0339, s = 0.9661, MS = 0.0200, NS = 0.0139, Ms = 0.5500, Ns = 0.4161; Fya =(More)
This paper is concerned with a weakly coupled system of quasilinear parabolic equations where the coefficients are allowed to be discontinuous and the reaction functions may depend on continuous delays. By the method of upper and lower solutions and the associated monotone iterations and by difference ratios method and various estimates, we obtained the(More)
