本文对137例HBsAg阳性者血清,用ELISA方法检测了HBeAg、抗-HBe、抗-HCc、抗-HBs。结果显示(1)HBsAg滴度与HBeAg、抗-HBe的阳性率密切相关;(2)抗-HBe的滴度普遍较高,都≥1:128;(3)低年龄组的HBeAg阳性率高于高年龄组,而低年龄组的抗-HBe阳性率则低于高年龄组。结果提示;HBsAg阳性,特别是HBsAg的滴度持续≥1:128以及HBeAg阳性者,是乙型肝炎的重要传染源。
In this paper, 137 cases of HBsAg-positive sera were detected by ELISA HBeAg, anti-HBe, anti-HCV, anti-HBs. The results showed that (1) HBsAg titer was closely related to the positive rate of HBeAg and anti-HBe; (2) the titer of anti-HBe was generally higher, both ≥1: 128; (3) In high age group, the positive rate of anti-HBe in lower age group was lower than that in higher age group. The results suggest that HBsAg positive, especially the HBsAg titer sustained ≥1: 128 and HBeAg-positive, is an important source of hepatitis B infection.
