RESUMO
Objective To investigate the effects of total flavonoids in Gingko Biloba on glucose and lipid metabolism and liver function in rats with insulin resistance. Methods Forty SD rats were randomly divided into normal control group,model group,total flavonoids in Gingko Biloba group and rosiglitazone group(positive drug control group)(n=10).Models of insulin resistance were established by high glucose and high fat diet in model group,total flavonoids in Gingko Biloba group and rosiglitazone group.After treatment for 12 weeks,serum glucose,serum lipids,and parameters of insulin resistance,liver function and anti-oxidation capability were detected in each group,and histologic observations of liver tissues were conducted with adipose staining. Results The serum glucose,insulin resistance index(HOMA-IR),insulin action index(IAI),serum total cholesterol(TC),triglyceride(TG),liver malondialdehyde(MDA) and serum transaminase activity in total flavonoids in Gingko Biloba group were significantly lower than those in model group(P
