The present study was conducted to determine the antidiabetic effect of Momordica charantia on pancreatic islets Langerhans in streptozotocin-induced diabetic male Wistar rats relation distribution insulin immuno-positive beta cells. fed at 2 %, 5 % and 10 standard diet for 12 w. After sacrifice, tissues were obtained histopathological immunohistochemical observations. In addition, monitoring f...
The vascular network supporting the islets of Langerhans represents a highly specialised system arterioles, capillaries and venules. Several features islet vasculature (density fenestration capillaries) ensure rapid exchange nutrients hormones, which is central to islets' capacity control systemic metabolism via reciprocal changes insulin glucagon secretion. Here we discuss how in blood flow ma...
Background: Glucokinase serves as a glucose sensor in pancreatic β-cells and plays a key role in glucose homeostasis and glucose-stimulated insulin secretion (GSIS). In the present study we examined the effect of glucosamine, a glucokinase inhibitor, on the pancreatic glucokinase and hexokinase activities and on insulin secretion from freshly rat pancreatic islets of Langerhans. Insulin concen...
To understand the dynamics of islet population, especially during conditions with growth of the total islet mass, it is important to have reliable estimators of parameters describing the quantitative appearance of the islet population. We describe a stereological estimator of the volume-weighted mean islet volume based on unbiased assumption-free stereological principles. The volume-weighted me...
