[Effects of different compatibility proportion of jiaotai pills on treating type 2 diabetes mellitus in rats].

Abstract

OBJECTIVE:

To study the effects of different compatibility proportion of Jiaotai pills on treating type 2 diabetes mellitus (T2DM) in rats.

METHOD:

The model of type 2 diabetes mellitus in rats was established by injecting streptozotocin from tail vein and feeding with high fat and high caloric diet. Diabetic rats were randomly divided into model group, Jiaotai pill 1 group (Coptidis Rhizoma-cinnamon 2: 1), Jiaotai pill 2 group (Coptidis Rhizoma-cinnamon 4: 1), Jiaotai pill 3 group (Coptidis Rhizoma-cinnamon 10: 1) and metformin group. Rats in different treatment groups were given by corresponding therapy from gastric tube. Meanwhile normal control group was another set. Body weight, oral glucose tolerance test (OGTT), blood lipid level including total cholesterol (TC), triglyceride (TG), high density lipoprotein-cholesterol (HDL-C) and low density lipoprotein-cholesterol (LDL-C), plasma levels of free fatty acid (FFA) and adiponectin, plasma liver enzymes activity(ALT, AST, AKP, gamma-GT) and pathological results of liver tissue were determined after eight weeks.

RESULT:

Body weight, fasting plasma glucose (FPG), postpradial plasma glucose at one hour (PG-1 h), postpradial blood glucose at two hour (PG-2 h), plasma levels of TC, TG, LDL-C, FFA and liver enzymes activity were all increased in rats of model group compared with those in normal control group. Plasma levels of HDL-C and adiponectin were decreased in model group (P < 0.01). Fatty degeneration of hepatocytes was apparent in liver tissues in rats of model group. Compared with model group results of OGTT, blood lipid levels and liver enzymes activity were improved while levels of HDL-C and adiponectin were increased in rats of different treatment groups (P < 0.05 or P < 0.01). Meanwhile fatty degeneration of hepatocytes was improved in liver tissues in rats of different treatment groups. Compared with metformin group, plasma level of HDL-C was elevated while AKP and gamma-GT were decreased significantly in rats of Jiaotai pill 1 group (P < 0.05), gamma-GT level was decreased significantly in rats of Jiaotai pill 2 group (P < 0.05), AST, AKP and gamma-GT levels were decreased significantly in rats of Jiaotai pill 3 group (P < 0.05). Compared with Jiaotai Pill 1 group, plasma levels of HDL-C was decreased while AKP levels was elevated significantly in rats of Jiaotai pill 2 group, but HDL-C was decreased in rats of Jiaotai pill 3 group (P < 0.05).

CONCLUSION:

It is suggested that different compatibility proportion of Jiaotai pills are effective on treating type 2 diabetes mellitus in rats. The effect of Jiaotai pill 1 group is better than that of other therapy groups.
