启东原发性肝癌血清中乙型肝炎病毒Ⅱ型(HBV2)感染可能性的初步研究

 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_2 Infection of Serum of Primary Liver Cancer in Qidong

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.
