Structural-functional reorganization of nonapeptidergic neurosecretory hypothalamic nuclei in experimental acute

Abstract:
Structures of the pancreas and magnocellular (supraoptic and paraventricular) nuclei of the hypothalamus of adult male rats were studied in conditions of acute pancreatitis at the light and electron microscopic levels. Histo-and organotypic changes in the parenchymatous and stromal elements of the pancreas were analyzed simultaneously with cytological assessment of the state of the nonapeptidergic neurosecretory centers of the hypothalamus. Blockade of the release of hypothalamic nonapeptides was found to occur at the level of axovasal complexes, and this aggravated the outcome of destructive and necrobiotic changes in the pathologically altered organ.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
