OBJECTIVE
To compare the duration and effects of aqueous methanol Acacia-nilotica leaves extract and glibenclamide as hypoglycaemic and hypolipidaemic activity in diabetic rats.
METHODS
The experimental study was conducted at Shifa International Hospital in collaboration with National Institute of Health, Islamabad, from September 2010 to August 2011.Male Sprague Dawley albino rats were taken and divided into 8 equal groups. Groups I and II were the normal and diabetic control rats. Diabetes mellitus was induced in group II to VIII by administering 110 mg/kg body weight alloxanand at day 4, fasting blood glucose level of >200 mg/dl confirmed diabetes. Acacia-nilotica leaves extract was given to group III, IV and V and glibenclamide to group VI to VIII for a period of 1-3 weeks. Blood samples were analysed for lipid profile using enzymatic calorimetric method and serum insulin by enzyme-linked immunosorbent assay on days 0, 7, 14, and 21.
RESULTS
There were 64 rats in the study, with 8(12.5%) in each group. Statistically significant decreases in fasting blood glucose, total cholesterol, triglyceride, phospholipids, low density lipoprotein, very low density lipoprotein and an increase in high density lipoprotein and serum insulin levels were observed in diabetic rats compared to diabetic controls after 2 weeks of treatment with plant extract and glibenclamide (p<0.05 each).When plant extract and drug treated diabetic rats were compared, a significant difference in the levels of blood glucose, insulin, total cholesterol and triglyceride levels were noted after 2 and 3 weeks of treatment.
CONCLUSIONS
Acacia-nilotica leaves extract resulted in hypoglycaemic and hypolipidaemic effect in alloxan-induced diabetic rats similar to glibenclamide.
