摘要
运用经典血清学方法首次在红鯽中证明了一种与金枪鱼中的A-B-O血型及人类的ABO血型模式相似的红细胞抗原系统,命名为S血型系统。该系统有四种血型表型:S^1,S^2,S^2S^2和S^0,推测它由S^1、S^2和S^0三个复等位基因决定。
This paper investigated erythrocytic antigen differences between individuals in R. C. Carp population using routine serlogical methods. This antigen system is nominated as S blood type (or group) system. Based on the results of isoagglutination and isoantibody and rabbit antiserum absorption tests, four blood phenotypes were revealed: no antigen(type Ⅰ, S^0), two antigens(type Ⅱ, S^1S^2) and single antigen(type Ⅲ, S^1 and type Ⅳ, S^2). In serum, type Ⅰ has anti-S^1 and anti-S^2, type Ⅱ has no antibodies, type Ⅲ has anti-S^2, and type Ⅳ has anti-S^1. This blood type system is similar to the phenotype models of 'A-B-O' type in tuna and ABO type in human being, but is different from the model in deer mouse which has only 3 phenotypes, A, AB and B, possibly controlled by two alleles alabelled P^A and P^B. It has been assumed that S blood type in R. C. Carp is determined by 3 multiple alleles labelled S^1, S^2 and S^0 (here S^1 and S^2 are codominant, and S^0 is most likely to be recessive). Although the genetic background of S system is possibly similar to that of human ABO. the results of agglutination test between human 'A' and 'B' serum and four types of S system in R.C.Carp showed that S system is a particular blood type independent of human ABO. The primary data present a much higher S^1S^2 ratio(6/16) in R.C.Carp than in human AB type. Further investigations of crossing between genotypes for S system are in process.
