To better understand the relationship between the endocrine and exocrine cell types in the Xenopus pancreas, we have cloned the Xenopus amylase cDNA and compared its expression profile with that of four other pancreatic markers: insulin, glucagon, elastase and trypsinogen. Our results demonstrate that the first pancreatic marker to be expressed is insulin, exclusively in the dorsal pancreas. Th...

Freeze-dried pancreas sections from 7-, 17- and 27-week-old genetically diabetic (db/db) and normal (+/-/+/-) mice were subjected to proton bombardment and the concentrations of 15 elements in B cells and exocrine pancreas were calculated from the characteristic X-rays emitted. In the 7-week-old diabetic animals, B cells contained significantly above-normal levels of Na and S, while exocrine pa...

BACKGROUND Simultaneous occurrence of exocrine and neuroendocrine tumors of the pancreas is very infrequent. We report a patient with an endocrine tumor in the pancreatic-duodenal area and extensive exocrine carcinoma involving the whole pancreas. CASE PRESENTATION A 69-year-old woman was hospitalized in May 2016 for epigastric pain and weight loss. Her past medical history revealed an undefi...

BACKGROUND & AIMS Progression of diseases of the exocrine pancreas, which include pancreatitis and cancer, is associated with increased levels of cell stress. Pancreatic acinar cells are involved in development of these diseases and, because of their high level of protein output, they require an efficient, unfolded protein response (UPR) that mediates recovery from endoplasmic reticulum (ER) st...

Objectives: Chronic pancreatitis, a benign inflammatory process of the pancreas resulting in exocrine and endocrine sufficiency. Pain is most devastating symptom, for which patient seeks medical advice. Even though these problems are addressed medically, surgery indicated many cases intractable pain. Methods: Thirty- patients who managed surgically during November 2018 to October 2020 at our in...
