Abstract:
Objective To explore the expression of CTGFmRNA and MDA in rats with alcoholic hepatic fibrosis and intervention of Huangqi injection on them.Methods 45 male SD rats were randomly divided into three groups:a normal group,a model group,and a Huangqi injection group.Alcohol was intragastricly administrated for 16 weeks to induce the model of hepatic fibrosis.At the same time of modeling,The Huangqi injection was injected into tail vein of rats in the Huangqi injection group.The rats were killed after 16 weeks.The histomorphylogic structure of the liver tissues were observed under optical microscope;The levels of MDA in liver tissue were determined by radioimmunoassay,and the expressions of connective tissue growth factor(CTGF)mRNA were measured by reverse transcriptase-polymerase chain reaction(RT-PCR).Results Compared with the model group.the destructions and proliferations of collagen fibers were lightened,fiber cords were loosened and narrowed swelling of liver cells and degeneration were alleviated,infiltrating cells got decreased(P＜0.01)in the treated groups;Compared with the model group,the collagen area,the MDA and CTGFmRNA expression in liver tissue were decreased obviously in Huangqi injection group(P＜0.01).The expression level of MDA and CTGFmRNA was positively correlated with collagen area(R_1=0.571,P＜0.05;R_2=0.558,P＜0.05).Conclusion Huangqi injection can protect liver from chronic damage in rats and obviously decrease hepatic fibrosis,which is closely correlated to its inhibiting the expression of CTGFmRNA in liver tissues and anti-lipid peroxidation.
