Abstract

The present study was aimed to explore the biochemical effect Ezetimibe/ Simvastatin and Ginger in
hyperlipidemic and diabetic male albino rats induced by feeding rats high-fat diet for 4-weeks with
intraperitoneal injection of a single low dose of streptozotocin (50 mg/kg) to explore the glycemic
condition, lipids and lipoproteins profile, hormones, oxidative stress and antioxidant status. Sixty male
albino rats were divided into four groups (15 rats each). Group I: Normal control rats fed on normal
ration, received no drugs. Group II: Hyperlipidemic and Diabetic rats, received no drugs and act as +ve
control .Group III: Hyperlipidemic and Diabetic rats treated with Ezetimibe/Simvastatin at a dose of 1.8
mg/kg/b.w/day orally for 4 weeks. Group IV: Hyperlipidemic and Diabetic rats treated with ginger root
aqueous extract at a dose of 400 mg/kg/b.w/day orally for 4 weeks. The obtained results revealed that
hyperlipidemic and diabetic rats showing highly significant increase in plasma glucose level, Total
cholesterol (TC), Triacylglycerol (TG), Low-density lipoproteins (LDL-C), Very low density
lipoprotein (VLDL-C), insulin, insulin resistance (IR), insulin receptor, leptin and L-Malondialdehyde,
(L-MDA). On the other hand, plasma High-density lipoprotein-cholesterol (HDL-C) and Total
antioxidant capacity (TAC) were showed a different behavioral pattern, where it was detectably
significant decrease. Treatment with Ezetimibe/Simvastatin and administration of ginger root extract
improved glucose levels, oxidative stress, and insulin resistance and exert antioxidant properties beside
its anti-hyperlipidemic activity.
