BACKGROUND AND AIMS The majority of patients with chronic pancreatitis are alcoholics. Our goal was to develop a mouse model of alcohol dependent chronic pancreatitis. METHODS Mice were fed either the non-alcohol containing Lieber-DeCarli diet or the Lieber-DeCarli diet containing 24% of calories as ethanol. After eight weeks and while on their respective diets, mice were subjected to repeate...

In the present study, the effects of caerulein and CCK receptor antagonist< on tolerance to the anti-pentylenetetrazol activity of diazepam has been studied. Different doses of diazepam (20, 30, 35, 40 and 50 mg/kg) were administered intraperitoneally for a period of 6 days in order to induce tolerance to diazepam. 48 h after the last dose of diazepam, a test dose of diazepam was tested for...

The pancreatic exocrine secretory response to different combinations of the pancreozymin-like peptide caerulein and secretin was studied in 110 healthy control subjects and 32 patients with pancreatic disease. A combination of 0 5 CU/kg-h secretin and 75 ng/kg-h caerulein provided maximal or near-maximal stimulation of the secretion of both bicarbonate and pancreatic enzymes. The combination of...

OBJECTIVES In the present study, we investigated the protective effects of Shen-Fu injection (SFI) on a caerulein-induced rat pancreatitis (AP) model. METHODS SFI was given to rats in the SFI treated group through intraperitoneal injection. Blood and pancreas samples were collected for serological and histopathological studies. RESULTS Our results showed that AP caused significant decrease ...

In rat pancreatic acinar cells, the Ca2+-mobilizing receptor-agonist, caerulein, at both maximal and submaximal concentrations, stimulated a rapid, transient, increase in [3H]inositol 1,4,5-trisphosphate [(1,4,5)IP3], followed by a slower, sustained, increase in [3H]inositol 1,3,4-trisphosphate [(1,3,4)IP3]. Neither activation of protein kinase C by phorbol dibutyrate nor prevention of the caer...

The effect of taxol, which is a microtubule stabilizer, was examined in a model of acute edematous pancreatitis induced in rat by the administration of caerulein. Prophylactic administration of taxol ameliorated inhibition of pancreatic secretion, increased level of serum amylase, pancreatic edema, and histological alterations in this model. Immunofluorescence studies revealed that taxol stabil...
