Effect of Ganoderma lucidum hydroalcoholic extract on insulin release in rat-isolated pancreatic islets
Objective: Ganoderma Lucidum (G. Lucidum) has been suggested to increase serum insulin level.This study was undertaken to investigateits direct effect on the islets of Langerhans. Material and Methods: Male albino Wistar rats were anesthetized and the islets were isolated after digestion of the pancreas with collagenase. The islets were incubated for 60 min in Krebs bicarbonate buffer containi...
متن کاملKinetics of somatostatin receptor migration in isolated pancreatic islets.
Eighty-seven percent of the total cellular pool of somatostatin (SRIF) receptors in pancreatic islets are located intracellularly. Upon glucose stimulation (300 mg/dl) of insulin release, 8-15% of intracellular SRIF receptors are translocated to the plasma membrane. Affinity of SRIF receptors does not change during their migration and the total cellular pool of receptors remains constant. With ...

متن کاملGlucose-stimulated 45Calcium efflux from isolated rat pancreatic islets.
Kinetics of (45)Ca efflux and insulin release were studied in collagenase-isolated rat islets during 2-h perifusions with calcium-depleted (0.05 mM) bicarbonate-phosphate buffer containing 2.2 mM glucose. Addition of glucose (16.7 mM) suppressed (45)Ca efflux by 30%. Removal of glucose caused an "off response" of insulin release. The perifusion of a normal concentration of Ca (2.3 mM) greatly s...
متن کاملInvestigation of β-Sitosterol and Prangol Extracted from Achillea Tenoifolia Along with Whole Root Extract on Isolated Rat Pancreatic Islets
The genus Achillea (Asteraceae) consists of important medicinal species, growing wildly in Iran, of which A. tenuifolia is found in Iran-o-Turan regions. Regarding the traditional use of Achillea species for treatment of diabetes and also lack of information on phyto-constituents of A. tenuifolia underground parts, in this study the results of anti-diabetic activity of this plant have been repo...
