Study the Effects of Polyphenolic Cocoa beans Extracts (CE) in Streptozotocin-induced diabetic mice

Diabetes Mellitus is a group of metabolic diseases characterized by increasing of glucose level in plasma compared with normal value (hyperglycemia). This disease also causes elevation of lipid profile levels except HDL (High density lipoproteins) which increased relatively. The effects of the polyphenolic mixture (catechins, epicatechins, procyanidin B1, procyanidin B2 and procyanidin C1) on total cholesterol (TC), triacylglycerol (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were studied in (30) streptozotocin-induced diabetic mice with (20-25)gm weight. Mice were given (30 mg/mL) of Polyphenolic Cocoa beans Extracts (CE) once daily for (7) days before Streptozotocin STZ injection and for (21 day) there after. At (day7) (TC), (TG) and (LDL) levels were elevated (P 0.001) and (HDL) level was decreased (P 0.001) compared with control group because of the effect of streptozotocin. A decreasing of (TC), (TG) and (LDL) (P 0.05) and increasing of HDL levels (P 0.05) at (day 21) were proved because of the protective effect of polyphenols against oxidative stress.
