Abstract

To investigate the protective effect of acupuncture intervention on liver in carbon tetrachloride induced hepatic fibrosis rats and to reveal its impact on extracellular matrix production in the liver tissue. A total of 46 SD rats were randomly divided into control group (n = 10), model group (n = 12), sham group (n = 12) and acupuncture group (n = 12). Hepatic fibrosis model was established by intraperitoneal injection of 50% olive oil containing CCl (1 mL/kg), 3 times in the 1st week and twice per week from the 2nd to the 6th week. During the fibrosis model establishment, acupuncture of "Taichong" (LR 3), "Qimen" (LR 14), "Ganshu" (BL 18) and "Zusanli" (ST 36) was carried out simultaneously. In the sham group, non-acupuncture points (0.5 cm left to the above-mentioned real points) were punctured. The treatment was conducted 3 times a week in the first three weeks and then twice a week for the last three weeks. Serum levels of hyaluronic acid (HA), liminin (LN) and precollagen (PC III) were determined by enzyme linked immunosorbent assay for assessing the hepatic fibrosis degree. Primary hepatic stellate cells (HSC) were separated. Western blot assay was used to detect the expression of alpha-smooth muscle actin (SMA), alpha 1...Continue Reading
