Palabras clave: | Chromagranin A Panreastatin Pancreas Rat Renovascular hypertension |
Resumen: | Hypertension significantly increases the risk of hyperglycemia in patients. It is known that chromogranin (CgA) and pancreastatin (PST) are involved in regulation of blood pressure and endocrine function of the pancreas. However, still little is known about the physiology of these hormones’ secretion in hypertension. The objective of the study was to examine the effects of hypertension on pancreatic islet cells containing CgA and PST in rats. The studies were carried out on the pancreas of rats. After 6 week period of the renal artery clipping procedure, eight 2K1C rats developed stable hypertension. Cells containing CgA and PST were detected using immunohistochemical method. The hypertension significantly decreased the number of pancreatic endocrine cells immunoreactive to CgA and PST antisera. The differences between the hypertensive and normotensive rats concerned not only the number of endocrine cells but also intensity of reactions. In conclusion, the research results indicate that hypertension causes the diminished biosynthesis of CgA and PST in the pancreas of rats and suggests the participation of those peptides in pancreatic disorders occurring in a state of elevated blood pressure. |
