对80例病毒性乙型肝炎无症状携带者和18例急性乙肝患者外周血进行电镜超微结构研究,Dane颗粒检出率分别为28.75%和88.89%,总检出率为39.80%,当抗-HBc IgM滴度≥1:1000时,则Dane颗粒检出率为100%;在HBsAg无症状携带者中,抗-HBc IgM、抗-HBc IgG阳性者检出率分别为35.14%和23.26%(P>0.05)。以HBsAg无症状携带者抗-HBc IgM滴度≥1:1000和<1:1000为分界线,则前者与急性乙肝患者组相比;后者与抗-HBc IgG阳性组相比,Dane颗粒检出率均无显著性差别,各组间传染性是相同的。
The ultrastructure of peripheral blood in 80 cases of viral hepatitis B asymptomatic carriers and 18 cases of acute hepatitis B were detected by electron microscopy. The detection rates of Dane particles were 28.75% and 88.89%, respectively, with a total detection rate of 39.80% -HBc IgM titer≥1: 1000, the detection rate of Dane particles was 100%; in HBsAg asymptomatic carriers, the detection rates of anti-HBc IgM and anti-HBc IgG were 35.14% and 23.26% (P> 0.05). HBsAg asymptomatic carriers of anti-HBc IgM titer ≥ 1: 1000 and <1: 1000 as the dividing line, the former compared with the group of patients with acute hepatitis B; the latter with anti-HBc IgG positive group, Dane particles There was no significant difference in the rates of outbreaks among the groups and the same was true for the groups.
