Effect of the Banxia-Xiexin decoction on express of glucose homeostasis of diabetic rats

Abstract

Objective To study the effects of the BanxiaXiexin decoction (BD) on express of glycogen synthesis and the expression of MC4R.and to discuss the mechanism of its maintaining glucose metabolism balance.Methods Diabetic mice were induced and divided into the model group,metformin group(0.3 g/kg)and BD high dose group(1.7 g/kg),medium dose group(0.85 g/kg),and low dose group (0.425 g/kg).In addition,a normal group was set to feed normal diet.Fasting blood glucose,body weight on an empty stomach,express of MC4R and hepatic glycogen were assayed after a week of treatment.Results Body weight of BD high,medium and low dose group was (296.62 ±1.14) g,(293.83 ± 2.1 7 ) g,and (286.75 ± 1.91 ) g respectively,showing a significant increase compared with the model group (284.73± 2.91) g (P＜0.01).MC4R expression of these MD groups were (29.69 ± 1.64) ng/L,(29.38±1.88) ng/L and (30.04 ±1.24) ng/L,showing a significant increase compared with the model group (25.95±2.24) ng/L (P＜0.05).Liver glycogen content of these MD groups were (15.94±0.82)mg/g,(11.52±0.56)mg/g,and (10.48±0.45)mg/g respectively,also showing a significant increase than the model group (9.05±0.44)mg/g(P＜0.01,P＜0.01,P＜0.05).Conclusion BD improves MC4R expression and rat feeding behavior by increasing by peripheral organization utilization of glucose.
