摘要
目的探讨H抗原在AB亚型中分布的规律,对AB亚型的正确鉴定提供帮助。方法用血清学试验与分子生物学相结合的方法确定各种AB亚型,对检出的39例A2B和45例其它AB亚型做H抗原检测,并与正常O型、B型细胞比较,判断其H抗原的强度。当AB亚型的H抗原凝集评分高于B型红细胞2分或2分以上时,认为该AB亚型上存在较多的H抗原。结果只在CisAB(100%),B(A)(100%),AxB(46.2%)以及A2B(43.6%)上发现了大量H抗原,而在其它众多的AB亚型中,H抗原与B型红细胞比较没有明显增强。结论大多数H抗原的增强现象可以用“3型H抗原”的残留来解释,但是对于53.8%AxB、56.4%A2B以及A3B、AmB中H抗原不增强的现象尚无合理的解释。
Objective To find the rule of the distribution of H antigens on AB subgrouperythrocytes.Methods ABO subgroups were confirmed by using serological and molecular biology (PCR-RFLP) methods. AB subgroup with strong H was defined as red cell agglutination by anti-H of 2 scores or more higher than that of B cells.Results Strong H was only found in certain AB subgroups ,CisAB(100%),B(A)(100%), AxB(46.2%) and A2B(43.6%), but seldom in others among Chinese population.Conclusion The fact that H type-3, which comes from A type-2, can hardly be transferred by B and weak A glycosyltransferase can help to explain why some ‘strong’ H combines with ‘weak’ A in AB erythrocytes. Why only little H can be found in 53.8% AxB, 56.4% A2B and all A3B, AmB subgroup samples still cannot been explained.
