this study was conducted to determine the properties of islets of langerhans in pancreas of adult and immature, male and female maquee sheep. for this purpose, 20 samples of pancreas were used equally for each male and female, immature and adult animals. paraffin sections that they were stained by h&e; method were used for mean distribution and dimension of langerhans islets, and maldonado stai...

objective(s): ghrelin is a peptide hormone that has been shown to have numerous central and peripheral effects. the central effects including gh secretion, food intake, and energy homeostasis are partly mediated by kiss1- kissr signaling pathway. ghrelin and its receptor are also expressed in the pancreatic islets. ghrelin is one of the key metabolic factors controlling insulin secretion from t...

In the present study, pancreas glands in Mehraban breed of female sheep were histomorphometricallystudied in four different age groups included: fetus, newborn, sexually mature and old ages. The results ofhistomorphometrical analysis with regard to frequency and percentage of parenchymal and stromal structures such as, exocrine secretory units, secretory ducts, blood vessels, islets of Langerha...

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...

isolation of rat islets of langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of hanks' solution into the common bile duct. the identification of the islets was done by techniques including the use of a stereomicroscope against a black background. vital staining was done by an injection of neutral red solution through ...

the final treatment for diabetes is transplantation of islets of langerhans. one of the new proposed methods for immunological preservation of transplanted cells is coating of cell surface by polyethylene glycol. in this study, the surface of islets of langerhans was coated by cyanuric chloride activated methoxy polyethylene glycol. the effect of polymer coating, at two different reaction times...
