Inflammation and cell death are critical to pathogenesis of acute pancreatitis. Here we show that transcription factor nuclear factor-κB (NF-κB), which regulates these processes, is activated and plays a role in rat cerulein pancreatitis. NF-κB was strongly activated in the pancreas within 30 min of cerulein infusion; a second phase of NF-κB activation was prominent at 3-6 h. This biphasic kine...
The premature activation of digestive enzyme zymogens in the pancreatic acinar cell is an important initiating event in acute pancreatitis. We have previously demonstrated that vacuolar ATPase (vATPase) activity is required for zymogen activation. Adenosine monophosphate-activated protein kinase (AMPK) regulates vATPase function in kidney and epididymal clear cells. To determine whether AMPK co...
OBJECTIVES We aimed to evaluate the anti-inflammatory and inhibitory effects of Lithospermum erythrorhizon (LE) on cerulein-induced acute pancreatitis (AP) in a mouse model. METHODS Acute pancreatitis was induced via intraperitoneal injection of cerulein (50 μg/kg) every hour for 6 times. In the LE, water extract (100, 250, or 500 mg/kg) was administered intraperitoneally 1 hour before the fi...
Objective(s): The objective of the present study is to explore whether Nanocurcumin improves pancreatic inflammation through the inhibition of the TLR4/NFkB signaling pathway in cerulein-induced acute pancreatitis. Methods: Acute pancreatitis was induced by five intraperitoneal (i.p.) injection of cerulein (50 μg/kg) with 1h intervals. Vehicle and nanocurcumin (100mg/kg/day) were given to the a...
OBJECTIVE To analyze the biochemical and histopathological effects of everolimus in an experimental rat model of cerulein-induced acute pancreatitis. The aim of the present study was to determine the effects of everolimus on blood biochemical parameters and tissue histopathology in an experimental rat model of cerulein-induced acute pancreatitis. MATERIAL AND METHODS In 30 Wistar albino rats ...

Acute pancreatitis (AP) is a potentially lethal disease characterized by inflammation and parenchymal cell death; also, the severity of AP correlates directly with necrosis and inversely with apoptosis. However, mechanisms of regulating cell death in AP remain unclear. The endoplasmic reticulum (ER) chaperone protein GRP78 has anti-apoptotic properties, in addition to modulating ER stress respo...
This study aimed to assess the role of oxygen free radicals in acute pancreatitis. Acute pancreatitis was induced in rats by infusion of the CCK-analogue cerulein (5 micrograms/kg per hour) for 30 minutes, 3.5 hours, and 12 hours. After the infusion, serum enzymes and conjugated tissue dienes and malondialdehyde were measured and tissue samples were subjected to electron and light microscopy. E...
Many inflammatory chemokines release from leukocytes and pancreatic acinar cells which play important roles in pathophysiology of acute pancreatitis (AP). Of interests, CXCL2 and CCL2 have been shown elevated in the plasma of patients with AP. We have recently found that Glycyrrhizin (GZ) attenuates AP in mice model. In this study, we aimed to investigate the direct effect of GZ on expression l...
Objectives. This study was conducted to clarify whether or not Tregs are involved in the development of immune-mediated pancreatitis in MRL/Mp mice as an AIP (autoimmune pancreatitis) model, in order to understand more clearly the pathogenic mechanism of AIP. Methods. We compared the immunohistochemical features of pancreatic forkhead box P3 (Foxp3) in the administration of poly I:C in MRL/Mp m...
