Abstract

OBJECTIVE

To study the pathological changes of blood glucose, serum lipid, insulin resistance, liver function, liver cell denaturalization of total glucosides of paeony on nonalcoholic fatty liver rats caused by insulin resistance and discuss the acting mechanism.

METHOD

Adult SD rats were maintained on high-fat-sugar-salt diet for 56 days. In the 57th day, their fasting blood glucose (FBG) and 2-hours blood glucose after oral glucose tolerance test (OGTT-2 hBG) were mensurated, according to which and the weight the rats were divided randomly into nonalcoholic fatty liver model group, metformin group (0.2 g x kg(-1)) and total glucosides of paeony group (high dosage 0.15 g x kg(-1), low dosage 0.05 g x kg(-1)). All the rats were still administered the same diet and given different drugs by intragastric administration for 28 days. In the 29th day, all of them were killed and the blood was sampled to measure the levels of blood glucose [FBG, OGTT-2 hBG, fasting insulin (Fins)] and serum lipid [free fatty acids (FFA), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)], then the HOMA insulin resistance index (HOMA-IRI, fasting glucosexinsulin) and insulin sensitivity index (ISI) were counted. The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholinesterase (ChE), superoxide dismutase (SOD) and the contents of malondialdehyde (MDA) were measured also. Livers were weighed and collected to be observed the pathological changes.

RESULT

Compared with normal group, in nonalcoholic fatty liver model group the levels of Fins and IRI were increased obviously (P < 0.01), ISI were decreased (P < 0.01), FFA, TG, TC, LDL-C were increased (P < 0.01), HDL-C were decreased (P < 0.05); the content of MDA were increased (P < 0.05), the activities of SOD were decreased (P < 0.01); AST, ALT and ChE were increased (P < 0.05, or P < 0.01), the pathological changes of liver fat were severe (P < 0.01). In glucosides of paeony group and metformin group, hyperinsulinaemia and insulin resistence were resisted (P < 0.05, or P < 0.01); the levels of FFA, TG, TC, LDL-C were decreased and HDL-C were increased (P < 0.05, or P < 0.01); the activities of AST, ALT, ChE were decreased (P < 0.05, or P < 0.01) and SOD were increased (P < 0.01). The contents of MDA were decreased (P < 0.05). The levels of FBG and 2 hBG in metformin group were decreased but in total glucosides of paeony group were not decreased obviously.

CONCLUSION

Total glucosides of paeony may protect liver function and modulate serum lipid for the fatty liver rats caused by insulin resistance, and its action mechanism may be concerned with enhancing insulin sensitivity and antioxidative ability, decreasing serum lipid.
