Effect of aqueous extract of tops of date palm leaves on blood glucose of diabetic rats.

Present study was carried out to examine the effect of tops of date palm leaves extract on blood glucose of streptozotocin induced diabetic rats. Forty male Sprague Dawely rats (120-130g) were housed individually and randomly allocated to two main groups; diabetic group (n=30), and normal group (n=10) in the animal lab, Faculty of Agriculture and Veterinary Medicine, Qassim University, Saudi Arabia. An aqueous extracts were prepared from tops of date palm leaves (EDPL) and were orally administered to rats. Later, the determination of glucose, BUN, creatinine, uric acid, ALT, and AST was examined. Pancreas sample were taken for histopathological examination. It was clear that the higher the concentration of EDPL the lower the weight gain (P<0.001). Glucose concentration of normal group changed by - 0.79% and decreased by -20.4% among diabetic control group, while feeding 1% and 2% EDPL had no significant effects, and the higher the amount of EDPL the higher the concentration of blood glucose. The thought that tea made from date palm leaves decrease blood glucose level has been denied by the results of this study and this tea may worsen diabetes patient's status.
