Abstract
Hyperglycemia, the mark normal for diabetes and associated disorders are the main goals of natural diabetes therapies. In this context, the present research was designed to study the effects of fenugreek sprouts juice (FS), barley sprouts juice (BS), cell-free probiotic extract (cell-free PE), whey protein hydrolysate (WPH) and their mixture on diabetic rats. Free radical scavenging activity, total phenolic contents (TPC) and total flavonoid contents (TFC) of each item mentioned were determined. Diabetes was induced through the injection of male rats with a single intraperitoneal dose (45 mg/kg) of streptozotocin. After the development of diabetes, diabetic rats were orally administered daily with 1ml of with fenugreek sprouts juice, barley sprouts juice, cell-free probiotic extract, whey protein hydrolysate or their mixture until the end of the study period (45 day). Oral administration of fenugreek sprouts juice, barley sprouts juice, cell-free probiotic extract, whey protein hydrolysate and their mixture to diabetic rats significantly reduced fasting blood glucose levels and improved the lipid profile. All the studied items limit the reductions of haemoglobin concentrations and plasma α-amylase activities. Also all the studied items suppressed the elevation of malondialdehyde values and the reduction of catalase activities. Histopathological investigation of pancreas, liver and kidneys of the diabetic rats showed histological alterations. On the other hand, supplementations with the tested materials lead to relieving these injuries. Results revealed that fenugreek sprouts juice, barley sprouts juice, cell-free probiotic extract, whey protein hydrolysate and their mixture had promising effects towards hyperglycemia and associated disorders.
