We have recently observed an increased interest in gastro-entero-pancreatic neuroendocrine tumors (GEP NET). They are rare cancer types and therefore collaborative effort of specialists in various disciplines of medicine is necessary to work out the diagnostic and therapeutic guidelines. In this publication we present general guidelines of the Polish(More)
OBJECTIVES A randomized controlled trial was conducted to clarify whether continuous regional arterial infusion (CRAI) of protease inhibitor and antibiotic could reduce mortality rate of severe acute pancreatitis (SAP). METHODS Seventy-eight patients with SAP were included in the study. Thirty-nine patients were treated with CRAI, 31 patients completed(More)
AIM Acute pancreatitis (AP) is the most common and often severe complication of endoscopic retrograde cholangiopancreatography (ERCP). The early step in the pathogenesis of acute pancreatitis is probably the capillary endothelial injury mediated by oxygen-derived free radicals. N-acetylcysteine - a free radical scavenger may be potentially effective in(More)
In 1981, a new low-molecular-weight protease inhibitor, FUT-175 (nafamstat mesilate), was synthesized. Its preventive action against acute experimental pancreatitis (AEP) was detected. We studied the effect of FUT-175 on the blood count and aggregability of platelets in AEP in dogs. At 30 min after induction of AEP, the sensitivity to ADP increased more(More)
The neuroendocrine tumors of the stomach and duodenum constitute only minority of neoplasms in this localisation. However due to their clinical behaviour and/or hormonal syndromes they pose diagnostic and therapeutic challenge. They display distinct phenotypes, regarding their pathogenesis, pathology and clinical course. Herein we present Polish guidelines(More)
The involvement of phospholipase D (PLD) in phosphatidylcholine hydrolysis by epidermal (EGF), insulin-like (IGF-I), and basic fibroblast (bFGF) growth factors was investigated in rat pancreatic acini. Acini were prelabeled with [3H]myristic acid which is mostly incorporated into phosphatidylcholine. EGF, IGF-I, and bFGF caused significant and(More)
Cholecystokinin (CCK), CCK octapeptide (CCK-8), and caerulein (Cae) are the most potent trophic factors in the pancreas when given exogenously or released from the intestine. Recent studies have suggested that this growth-promoting effect of CCK was initiated through the occupation of the CCKA receptor. This study was then undertaken to determine whether(More)
The gastrointestinal hormone cholecystokinin and the muscarinic agonist carbamylcholine are involved in pancreatic enzyme secretion through phospholipase C activation and production of the second messengers inositol trisphosphate and diacylglycerol. However, cholecystokinin induces growth of the pancreas whereas carbamylcholine does not. This study(More)
The novel 38-amino acid neuropeptide PACAP (pituitary adenylate activating peptide) has recently been shown to induce the pancreatic acinar tumour AR4-2J cell growth. This growth promoting effect of PACAP was, however, independent of adenylate cyclase activation but suppressed by pertussis toxin and the somatostatin analog SMS 201-995. This study was(More)
BACKGROUND/AIMS Analysis of cystic fluid may be useful in distinguishing between benign and malignant cysts which has significant impact on their management. The aim of our study was to assess the diagnostic utility of carcinoembryonic antigen (CEA) and K-ras gene mutation in pancreatic cysts fluid. METHODS The study included 56 patients with pancreatic(More)
