Abstract

To examine the effect of green tea extract on body weight, serum levels of glucose, and lipids in streptozotocin-induced diabetic rats. This experimental study was carried out in the Diabetes Research Center, Ahvaz University of Medical Sciences, Ahvaz, Iran from January 2011 to March 2011. Forty-eight male wistar rats (200-250 g) were divided randomly into 6 groups. Diabetes was induced by a single intraperitoneal injection of stereptozotocin (55 mg/kg). The experimental groups received alcohol extract of green tea leaves (100 mg/kg and 200 mg/kg) for 4 weeks and the body weight of animals were measured every day. Finally, blood samples were collected and analyzed for glucose and lipid profile levels. Administration of green tea extract caused a significant decrease in serum glucose and total cholesterol levels and significantly improved the body weight loss in diabetic rats treated with 200 mg/kg green tea in comparison to diabetic control group. No significant changes were observed in triglyceride (p=0.04), low-density-lipoprotein cholesterol (p=0.000), and high-density-lipoprotein cholesterol levels (p=0.01) following intervention. It appears that green tea extract had both antihyperglycemic and hypocholesterolmic effects i...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
