启东原发性肝癌血清中乙型肝炎病毒Ⅱ型(HBV_2)感染可能性的初步研究

A Study on HBV_2 Infection of Serum of Primary Liver Cancer in Qidong

本文对肝癌高发区启东肝癌血清中是否存在乙型肝炎病毒Ⅱ型（HBV2）之可能性作了初步研究。结果显示：（1）672例肝癌血清中HBV2感染率为4．02％（2／672），占HBsAg阳性者的5．29％（27／510）；（2）HBV1与HBV2混合感染率为1．93％（13／672），占HBsAg阳性者的2．55％（13／510）。说明患者先前感染HBV1后，产生的抗－HBs不能阻止HBV2之再感染，提示将来研制乙肝疫苗时应包括有HBV2之表面抗原。

A study on HBV, infection of sora of primary liver cancer was made in Qidong The total infectional rate of HBV was 95. 39% (641/672). The infectional rate of HBV, was 4. 02% (27/672 ). It cocupied 5.29% (27/510) of the patients with HBaAg positive. The mixed infectional rate of HBV1 and HBV2 was 1. 93(13/672).Although the HBV, was infected ago and the anti-HBs was produced, the anti-HBs was not to prevent the HBV2 infection again. It suggests that the preparation of vaccines must contain the antigen of HBV2 in after.
