1983年浙江省部分医学科研项目进展情况如下: 乙型肝炎病毒子宫内传播的研究由浙江医科大学(浙医大)传染病研究所承担。该所从血清HBsAg阳性的孕妇中收集了因各种原因死亡的胎儿16例。经免疫电镜观察发现,7例胎儿血清沉积物和肝脏提出物中有HBV抗原颗粒,其中3例血清HBV DNA多聚酶活性升高;6例胎儿对HBV感染有免疫应答,产生IgM抗HBc;未标记酶抗体(PAP)法从4例胎
The progress of some medical research projects in Zhejiang Province in 1983 is as follows: The study on the intrauterine transmission of hepatitis B virus was undertaken by the Institute of Infectious Diseases, Zhejiang Medical University (Zhejiang University of Medical Sciences). The Institute collected 16 cases of fetal deaths due to various causes from serum HBsAg-positive pregnant women. Immuno-electron microscopy showed that seven cases of fetal serum sediments and liver proposition with HBV antigen particles, of which three cases of serum HBV DNA polymerase activity; six cases of fetuses have an immune response to HBV infection, resulting in IgM anti-HBc; unlabeled Enzyme antibody (PAP) method from 4 cases of fetal
