[Therapeutic effect of Haobieyangyinruanjianfang on the mouse liver fibrosis caused by schistosomiasis].

OBJECTIVE
To explore therapeutic effect of Haobieyangyinruanjianfang (HBYYRJ) on mouse liver fibrosis by schistosomiasis.


METHODS
Mice except for normal control were infected with Japanese schistosome cercarias, after 12 weeks, infected mice were divided into 7 groups: low HBYYRJ group, middle HBYYRJ group, high HBYYRJ group, Fufangbiejiaruangan tablet (FFBJRG) group, colchicine group, 3 months infection group and 6 months infection group. Hepatic fibrosis was found in 3 months infection group. Liver hydroxyproline (Hyp) was determined, matrix metalloproteinase-2 and 9 (MMP-2, MMP-9) were detected with gelatin zymography, serum hyaluronic acid (HA) and precollagen III (PC-III) were detected using RIA.


RESULTS
HBYYRJ obviously reduced hepatic fibrosis (probability value less than 0.01). Collagen and HA in 3 months infection group and 6 months infection group were higher than that in normal group (probability value less than 0.01), collagen in high and middle HBYYRJ groups and HA in middle and low HBYYRJ groups were lower than that in 6 months infection group (P less than 0.01, probability value less than 0.05). The expression of MMP-9 and MMP-2 in 3 months infection group and 6 months infection group was higher than that in normal group (probability value less than 0.01), The expression of MMP-9 in three HBYYRJ groups and the expression of MMP-2 in high HBYYRJ group were lower than that in 6 months infection group (probability value less than 0.05).


CONCLUSION
HBYYRJ can reduce liver fibrosis caused by schistosomiasis.
