In order to study the immune response of HB vaccine combined with BCGand DTP, 150 newborns of HBsAg negative. mothers were divided into threegroups and observed. Babies in groups 1 and 2 were given injection of 10μg,20μg HB vaccine respectively, group 3 had no HB vaccination. But all thethree ..., Abstract

The inhibitory effect of (s)-9-(2, 3-dihydroxypropyl) adenine ((s)-DHPA)on infection of Epidemic Hemorrhagic Fever Virus (EHFV) J10 strain in su-ckling mice was observed. The experimental results showed that the morbidityrate (44.44 % and 55.17%) and infection rate (44.44% and 55.17%) of ..., Abstract

Review
The susceptibility of human B lymphoblastoid cells to HFRS virus infectionwas studied. The results showed that the cells were productively infected byHFRS virus. The persistently infected cells had no obvious cytopathic effects andwere indistinguishable morphologically from uninfected cells. It was ..., Abstract

We established a stable human tonsillar cell culture-immunization systemin vitro, in which sheep red blood cells (SRBC), a virus-irrelevant antigen,induced efficiently specific antibody production. In contrast to traditional con-cepts, we demonstrated that adhering cells (mainly macrophages) in ..., Abstract

The microslide gel double diffusion test was used to detect potato leaf-rollvirus (PLRV). It was found to be sufficiently sensitive for the detection ofPLRV in extracts of infected plants. A 1: 4 dilution of extract of PLRV infectedpotato stem could be detected unambiguously. The sensitivity of ..., Abstract

This paper reports the results of studies on a Nuclear Polyhedrosis Virus(SiNPV) isolated from the mulberry caterpillar [Sacopolia illoba (Butler)]in Harbin. In most cases there were 4--5 nucleooapsids enveloped within eachvirus bundle of SiNPV. The polyhedra of SiNPV were 2. 06±0. 27μm in ..., Abstract
