METHODS： Rat liver fibrosis models were induced by CCl4 and alcohol administration. After 8 wk, twenty rats were randomly allocated into treatment group （n = 10） and control group （n = 10）. BMC were infused into the rats in treatment group via the portal vein, while heparinized saline was infused in control group. CCl4 was hypodermically injected into the rats twice a week for 4 wk. At the end of wk 12, all rats were humanely sacrificed. Uver samples were taken and stained with HE or Masson trichrome. The general conditions, liver fibrosis （hydroxyproline and collagen fibre） and liver pathological grades in rats were evaluated. RESULTS： The general conditions of the rats in treatment group improved markedly, but not in control group. Hydroxyproline was 504.6± 128.8 μg/g in treatment group, and 596.0 ± 341.8 μg/g in control group. The percentage of collagen fibre was 3.75% ± 0.98% in treatment group and 5.02% ± 0.44% in control group. There was a significant difference between the two groups （P 〈 0.05）. Liver pathological grade decreased from grade N to grade 11 partially in treatment group （P 〈 0.05） with no obvious improvement in control group （P 〉 0.05）. There was a significant difference between treatment group and control group （P 〈 0.05）.CONCLUSION： Transplantation of BMC can improve liver fibrosis due to chronic liver injury in rats.展开更多
