    Abstract:
    OBJECTIVE: To investigate the fat decreasing effects of fenofibrate on alcoholic fatty liver and drug-induced fatty liver in rats. METHODS: Alcoholic fatty liver and drug-induced fatty liver rats models were established. The two kinds of rats with fatty liver were seperatedly divided into fenofibrate treatment group (80 mg/kg daily) and control group without treatment. Rats were killed after four weeks, then the levels of serum triglycerides (TG), total cholesterol (TC), high density lipoprotein (HDL) and malondialdehyde (MDA), hepatic lipase (HL), lipoprotein lipase (LPL) both in serum and liver tissue were measured according to the Test Kits. Histopathological changes in liver was dyed with HE and observed under light microscope. RESULTS: After treatment by fenofibrate, in the serum of rats with alcoholic fatty liver, the level of TG decreased significantly (1.07 mmol/L 0.06 mmol/L vs 1.56 mmol/L 0.29 mmol/L, t=5.115, p<0.001), while the level of TC had no alteration. The levels of MDA both in serum and liver tissue decreased (1.10 nmol/L 0.22 nmol/L vs 1.26 nmol/L 0.21 nmol/L, t=0.592, p<0.05; 5.92 nmol/g 1.24 nmol/g vs 7.42 nmol/g 1.22 nmol/g, t=3.477, p<0.05, respectively), while the levels of HL, LPL in serum and liver tissue increased significantly (Serum: 0.053muEq/ml/h 0.006muEq/ml/h vs 0.037 muEq/ml/h 0.006muEq/ml/h, t=-5.086, p<0.001; 0.018 muEq/ml/h 0.004 muEq/ml/h vs 0.014muEq/ml/h 0.004muEq/ml/h, t=-2.485, p<0.05. Liver tissue: 0.075muEq/ml/h 0.010muEq/ml/h vs 0.065muEq/ml/h 0.007muEq/ml/h, t=-2.437, p<0.05; 0.022 muEq/ml/h 0.014 muEq/ml/h vs 0.008 muEq/ml/h 0.002 muEq/ml/h, t=-2.876, p<0.05). Fat content in liver decreased (26.01 mg/g 1.69 mg/g vs 71.45 mg/g 2.66 mg/g, t=-43.224, p<0.001). The pathological changes of liver in fenofibrate-treated rats with alcoholic fatty liver were improved. For the drug-induced fatty liver rats, fenofibrate treatment group had no difference from the untreated control group. CONCLUSION: Fenofibrate can significantly decrease the fat content in liver tissue of rats with alcoholic fatty liver, as well as ameliorating liver pathological changes. But fenofibrate has no effect on drug-induced fatty liver.
