OBJECTIVE
Although tumor necrosis factor alpha is implicated as an important mediator of the inflammatory response in acute pancreatitis, its role in other pathologic features of the disease remains unknown. We investigated the role for tumor necrosis factor alpha in cytoskeletal responses and the
Hypertriglyceridemia (HTG) is often associated with acute pancreatitis. The relationship between these diseases and the role that hypertriglyceridemia plays in acute pancreatitis pathogenesis remains to be elucidated. In the present study, in order to investigate the mechanisms of hyper-lipidemic
Collagen and non-collagen protein metabolisms in rat acute pancreatitis induced by ethionine were investigated with an incorporation study of 3H-proline to those proteins. Enhanced collagen metabolism, which may provide a basis for parenchymal cells regeneration, was observed in the initial phase of
Amylin is a pancreatic hormone cosecreted along with insulin and involved in pancreatic amyloidosis and β-cell apoptosis in diabetic cats and humans. Amylin is usually elevated in early stages of type 2 diabetes but recently was found to be increased in acute and chronic pancreatitis in humans.
Acute experimental pancreatitis was induced in male Wistar rats by retrograde injection of 0.4 ml 2% sodium taurocholate into the common choledochopancreatic duct. Prophylactic intraperitoneal injection of 20 mg glutaryl-trialanine-ethylamide, Glt-(Ala)3-NH-Et, 30 min. before induction of
Acute pancreatitis has several underlying etiologies, and results in consequences ranging from mild to complex multi-organ failure. The wide range of pathology suggests a genetic predisposition for progression. We compared the susceptibility to acute pancreatitis in BALB/c and FVB/N mice, coupled
Atthe Institute of Biochemistry named after H. Buniatyan we discovered and studied hypothalamic peptides with coronary dilatory and antioxidant activities:neurohormone C (NC) and proline-rich peptide-1 (PRP-1). Both NC and PRP-1 exhibit cardioprotective effects, in part by restoring the calcium
We have developed a convenient method combining fast protein liquid chromatography (FPLC) with sensitive radioimmunoassay (RIA) for thyrotropin-releasing hormone (TRH) to separate and identify TRH and its metabolite histidyl-proline diketopiperazine (CHP) and applied this to study inactivation of
BACKGROUND
Dietary proteins and amino acids can modulate pancreatic function.
OBJECTIVE
Our aim was to estimate the levels of plasma amino acids in chronic pancreatitis patients and study their relationship with disease characteristics as well as exocrine and endocrine insufficiency.
METHODS
One
Intrapancreatic activation of trypsinogen is believed to play a critical role in the initiation of acute pancreatitis, but mechanisms responsible for intrapancreatic trypsinogen activation during pancreatitis have not been clearly defined. In previous in vitro studies, we have shown that
OBJECTIVE
To demonstrate the relationship between prolonged alcohol intake and chronic pancreatitis.
METHODS
Wistar rats were fed diet containing 25% concentration (vol/vol) of ethanol for 6 months. Cholecystokinin (CCK) was quantified by radioimmunoassay. Immunohistochemistry was used to detect
The regeneration of the rat exocrine pancreas from a hormone-induced pancreatitis was investigated. In a previous study it was shown that the [3H]thymidine labeling index of interstitial cells increases 20- to 30-fold on day 1.5 after the induction of pancreatitis. Here we show by electron
BACKGROUND
The role of mutations in the serine protease inhibitor Kazal type 1 (SPINK1) gene in chronic pancreatitis is still a matter of debate. Active SPINK1 is thought to antagonize activated trypsin. Cases of SPINK1 mutations, especially N34S, have been reported in a subset of patients with
BACKGROUND
It is now generally accepted that chronic pancreatic injury and fibrosis may result from repeated episodes of acute pancreatic necroinflammation (the necrosis-fibrosis sequence). Recent studies suggest that pancreatic stellate cells (PSCs), when activated, may play an important role in
