107 fresh blood specimens and 22 blood specimens from the blood bank were detected by polymerase chain reaction (PCR) and ELISA. The positive percentage of detecting CMV DNA in the leukocytes of the blood specimens by PCR is 77.3—80.4%. Meanwhile the positive percentage of CMV-IgG in the plasma by ..., Abstract

In this study, three-week-old mice, 12—14g, were treated by cytoxan three times. They were then injected subcutaneousiy with SA_(14)-14-2 live vaccine, no mouse was killed by the attenuated virus. When the immune-inhibited mice were immunized with the attenuated live vaccine and the inactivated JE ..., Abstract

Review
The difficulties of rotavirus(RV) propagation in cell culture were not overcome completely, because not all groups of RV or not all strains of the same group of RV could replicate in vitro as yet. One of. the reasons of the difficulties might be that there ware only a few kinds of cells susceptible ..., Abstract

Review
In this paper we reported the detection of HCV-RNA in plasma of blood donors by nested double polymerase chain reaction method using two pairs of primers located in the 5 -terminal non-coding region. We found that nested double PCR method is much better than single PCR method both in sensitivity ..., Abstract

The polymerase chain reaction (PCR) was applied to identify the human papillomavirus (HPV) 6 and 11 DNA in the spcimens from 30 patients with condyloma acuminatum. The positive percentage of HPV6, HPV11 DNA was 60%, 90%, respectively. 53.3% samples showed the presence of both HPV6 and HPV11 DNA. ..., Abstract

Sweet potato feathery mottle virus (SPEMV) was purified from infected I.Nil leaves using ultracentrifugation and CsCl step gradient centrifugations. Virus yields of 13—15 mg Per kilogram of infected Ieaf tissue were obtained. The normal particle lengths of the SPFMV was 820—860nm. The virus ..., Abstract

Using hybridoma techniques, six monoclonal antibodies (mAb), P3, 4A4 6B1, 7A6, 7D1 and 7D8 to Freesia chlorotic stripe mosaic virus ( FCSMV), were prepared. The titers of mAb were 1:10~2—1:10~6. MAb 7A6 and 7D1 were IgG1 subclass. 7D8 and 4A4 were IgG2a and lgG2b subclass, respectively, mAb P3 and ..., Abstract
