Abstract
Diabetes mellitus is one of the most extensive diseases in the world. Olive tree leaves have been widely used in traditional therapies in European and Mediterranean countries as extracts, herbal teas, and powder. They contain numerous potentially bioactive compounds that may have hypoglycemic properties. Twenty-four adult Wistar rats were divided into four groups; (normal control), diabetic control (45 mg/kg STZ), normal rats treated with olive leaf extract (17.8 mg OLE /kg b.wt.), and diabetic rats treated with olive leaf extract (45 mg/kg STZ+ 17.8 mg OLE /kg b.wt.). Olive leaf extract was orally administrated for 10 weeks. The levels of serum iron, total iron binding capacity, ferritin, transferrin, hemoglobin, glycated hemoglobin, glycated albumin, GPX, SOD, GSH, CAT, MDA, lipid profile, heart function, Ü-amylase, glucose level, kidney and liver function were analyzed at zero time and after 10 weeks. Results showed that olive leaf extract significantly (P < 0.05) kept serum iron, total iron binding capacity in the normal range, and improved the ferritin, transferrin, and glycated hemoglobin and glycated albumin levels to make them less than the diabetic group levels. The OLE prevented the decrease of GSH and kept MDA around the normal range in the treated diabetic rats
