[Experimental study on effect of jinye baidu preparation in inhibiting human cytomegalovirus protein kinase pul 97].

Objective: To study the inhibitory effect of Jinye Baidu Preparation (JBP), a Chinese medicinal preparation, on human cytomegalovirus protein kinase pu197 and to explore its molecular mechanism in treating human cytomegalovirus (HCMV) infection.
Methods: Expression of the HCMV pu197mRNA in infected cells was measured by semi-quantitative RT-PCR before and after intervention of JBP or Ganciclovir (GCV), and effect of the two medicines on the proliferation activity of the infected cells was observed by MTT.
Results: Both JBP and GCV showed obvious inhibitory action on HCMV pu197mRNA. They could significantly enhance the proliferation activity of the cells 72 hours after HCMV infection.
Conclusion: JBP could inhibit the gene expression and duplication of HCMV by inhibiting the gene expression of HCMV protein kinase pu197 to enhance the proliferation activity of the infected cells so as to achieve its anti-virus action.
