Isolated Pancreatic Islets
It is the aim of this study to characterize and quantify the cells within isolated rat islets that express MHC class 11 antigens. A set of five monoelonal antibodies and two polyclonal antisera of defined specificlty were used in combination with a newly devised procedure for three·dimensional immunofluorescence evaluation of intact islets. It is shown that in addition to passen· ger cells, suc...
متن کاملIsolated Mouse Pancreatic Islets
Inosine is a potent primary stimulus of insulin secretion from isolated mouse islets. The inosine-induced insulin secretion was totally depressed during starvation, but was completely restored by the addition of 5mmi-caffeine to the medium and partially restored by the addition of 5mM-glucose. Mannoheptulose (3mg/ml) potentiated the eflect of lOmM-inosine in islets from fed mice. The mechanism ...
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...

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...
