Chemical compound and disease context of Pancreatectomy

 

Biological context of Pancreatectomy

  • Since an appreciable fraction of postprandial glucose disposal takes place in the absence of insulin (insulin-independent glucose disposal--IIGD), we have investigated potential changes in this aspect of carbohydrate metabolism before and after bladder-drained pancreatic auto-transplantation (PAT/B) as well as partial pancreatectomy (PPx) [15].
  • Together, these results suggest that in the adult hyperglycaemic GK/Par rat facing pancreatectomy, duct-cell proliferation and apoptosis from the common pancreatic duct, main ducts and small ducts were not impaired compared to the Wistar rat [16].
  • Expression of the c-myc and H-ras oncogenes, and of several genes specifically expressed in adult rat pancreas was investigated by monitoring changes in corresponding mRNA concentrations, by dot-blot hybridization, during the early phase of regeneration following subtotal pancreatectomy [17].
  • The objective of this study was to investigate the role of hypothalamic 5-HT, 5-HT1A and 5-HT2C receptor binding and gene expression in rat model of pancreatic regeneration using 60% pancreatectomy [18].
  • The effects of fetal pancreatectomy on the uptake of oxygen, glucose and lactate by the fetus, uterus and uteroplacental tissues were investigated in chronically catheterized sheep during the last third of gestation [19].

Gene context of Pancreatectomy

  • Immunohistochemical staining of tumor tissue removed at pancreatectomy was positive for ACTH and beta endorphin, and negative for corticotropin-releasing factor (CRF) [29].
  • In this study, cell morphology, proliferative response to serum, alpha-SMactin levels, eNOS expression and activity, cGMP intracellular content, and superoxide anion release were measured in cultures of vSMC obtained from aorta medial layer of ten diabetic (90% pancreatectomy, DR) and ten control (sham surgery, CR) rats [30].
  • After partial pancreatectomy, there was a transient increase of the number of anti-nestin-labeled endothelial cells, but again, no endocrine cells bore beta-galactosidase [31].
  • Dual role of the tyrosine kinase GTK and the adaptor protein SHB in beta-cell growth: enhanced beta-cell replication after 60% pancreatectomy and increased sensitivity to streptozotocin [32].
  • The purpose of this study was to investigate the role of central 5-HT2C receptor binding in rat model of pancreatic regeneration using 60-70% pancreatectomy [33].
