Therapeutic effect of Zijin capsule in liver fibrosis in rats.

AIM:To confirm the therapeutic effect of Zijin capsule on liver fibrosis in rat model.METHODS:Model group: Bovine serum albumin (BSA) Freund's incomplete adjuvant 0.5ml was injected subdermally at d(1) d(15) d(22) d(29) and d(36) for primary sensitization. Seven days after the fifth injection, BSA antibody in the serum was detected by double agar diffusion method. Normal saline of 0.4ml was injected through cauda vein to BSA antibody-positive rat twice a week for fifteen times. Traditional Chinese medicine (TCM) decoction group and Zijin capsule group: In the attack injection period, Chinese medicinal decoction or Zijin capsule was given ig, the others were the same as in the model group. NS was used in the control group. The collagen content of rat liver was determined by Bergman's method and expressed as x-±s.The liver pathological changes were divided into four grades and expressed as the avarage of the total rank sum.RESULTS:The collagen content (mg/g) of the liver in the control group (7.2± 1.9) was significantly lower than that in the other groups; it was higher in the model group (31.7± 16.6) than that in the two therapeutic groups; and lower in Zijin capsule group (9.7 ± 2.8) than that in the TCM decoction group (11.5± 5.3). The pathological changes were more aggravated in the model group (37.4) than those in the two therapeutic groups; and more severe in the TCM decoction group (30.2) than in the Zijin capsule group (22.9).CONCLUSION: The therapeutic effect of Zijin capsule on the model was confirmed.
