OBJECTIVE:To study the protective effects of total flavone from Prunus cerasifera fruits(PCE)on alcoholic liver disease(ALD)in rats,and provide experimental basis for developing new medicines for anti-ALD. METHODS:40 rats were ran-domly divided into normal group(distilled water),model group(distilled water),silibinin group [positive control,30 mg/(kg·d)] and PCE high-dose,low-dose groups [80,40 mg/(kg·d)],8 in each group. All rats were intragastrically administrated(10 mL/kg) every morning,once,for 6 weeks;meanwhile,except for normal group,rats in other groups received 50% alcohol(10 mL/kg) once intragastrically every afternoon to induce ALD model. After administration,heart,liver,spleen and other organ indexes,sub-cutaneous fat,brown fat,abdominal fat indexes were determined,as well as serum biochemical indexes [glutamate transaminase (ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),direct bilirubin(DBIL),indirect bilirubin(IBIL),gamma-glu-tamyl transpeptidase(GGT),and total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL),low-density lipopro-tein (LDL)] level and liver biochemical indexes [superoxide dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),TC,TG] and TC,TG levels in feces;pathological changes of liver and kidney tissues were observed. RESULTS:Compared with normal group,heart,liver,spleen indexes,subcutaneous fat,abdominal fat indexes in model group were in-creased(P<0.05 or P<0.01),brain index and brown fat index were decreased(P<0.05);HDL level and HDL/TC ratio in serum were decreased,other serum indexes were increased(P<0.05 or P<0.01);SOD,GSH-Px levels in liver tissue were decreased, other above-mentioned liver biochemical indexes were increased(P<0.01);TC,TG levels in feces were increased(P<0.01);liv-er and kidney showed obvious lesions. Compared with model group,the above-mentioned indexes in silibinin group and PCE high-dose group were significantly improved (P<0.05 or P<0.01);ALT,AST in serum and MDA level in liver tissue in PCE low-dose group were significantly decreased(P<0.01),and SOD,GSH-Px levels in liver tissue were significantly increased(P<0.05);lesion degree of liver and kidney and lipid accumulation in liver were reduced in administration groups. CONCLUSIONS:PCE may play a role in anti-ALD by anti-oxidation,promoting liver cell regeneration and regulating lipid metabolism.
