[Inhibition of quercetin on liver fibrosis due to Schistosoma japonicum infection and on the expression of immediate early gene and metalloproteinase 1 inhibitor in liver tissue of mice]

Abstract

Quercetin and praziquantel were used to treat mice with hepatic fibrosis due to Schistosoma japonicum infection. Quercetin treatment obviously relieved the degree of hepatic fibrosis, significantly reduced the expression of immediate early gene, tissue inhibitor of metalloproteinase 1 (TIMP 1), types I and III collagen compared to the control. The expression of c-jun mRNA, type I and type III collagen were reduced significantly compared to the group treated with praziquantel, whereas no difference in the expression of c-fos mRNA and TIMP1 between the two groups, indicating that quercetin may have better effect on schistosomal liver fibrosis than praziquantel in the long term.
