ABSTRACT
Objective: To research the effects of Zuogui Pill on the gene expression profile of regenerate hepatic tissue in MSG-liver regeneration-rat.Methods: MSG-liver regeneration-rat models were copied;therapy group were given Zuogui Pill(5g/kg) by intragastric administration.Rats were executed at the 5th day after operation,and the regenerate liver tissues were frozen by liquid nitrogen.1176 gene chips of gene expression profile correlated to cell differentiation and multiplication were adopted to observe the changes of gene expression profile in the regenerate liver tissues.Results: There were 292 differential expression genes in therapy group compared with model group(20 genes were up-regulation expressed and 272 genes were down regulation expressed).Conclusion: Zuogui Pill has significant effects on the gene expression profile of regenerate hepatic tissue in MSG-liver regeneration-rat,and most of the genes are down regulation expressed.The result hints that Zuogui Pill could influence the liver regeneration by regulating the gene expressions of MSG-live regeneration-rat.Down regulation of the gene expressions of regenerate hepatic tissue in MSG-liver regeneration-rat possibly is one of the important molecular mechanisms of Zuogui Pill in nourishing liver and kidney.
