AIMS: Pancreatitis is characterized by inflammatory disease with severe tissue injury in pancreas, and the incidence of pancreatitis has been recently increasing. Although several treatments of acute pancreatitis have been developed, some patients have been resistant to current therapy. Chlorogenic acid (CGA) is one of the polyphenols, and is known to have an anti-inflammatory effect. In this study, we investigated the effects of CGA on experimental pancreatitis in mice. MATERIALS AND METHODS: Pancreatitis was induced by twice injection of l-arginine (5g/kg body weight)...

INTRODUCTION: Acute pancreatitis (AP) is an inflammatory disease with no specific treatment. Mitochondrial injury followed by ATP depletion in both acinar and ductal cells is a recently discovered early event in its pathogenesis. Importantly, preclinical research has shown that intracellular ATP delivery restores the physiological function of the cells and protects from cell injury, suggesting that restoration of energy levels in the pancreas is therapeutically beneficial. Despite several high quality experimental observations in this area, no randomised trials have been conducted to date to address the requirements for energy intake in the early phase of AP...

Hemolytic-uremic syndrome (HUS) is characterized by acute kidney injury with hemolytic anemia and thrombocytopenia. It has diverse etiologies, clinical manifestations, and risk factors. Acute pancreatitis as a cause of HUS is rare in adults. We report a case of 32-year-old male who presented with ethanol-induced acute pancreatitis complicated with hemolytic-uremic syndrome managed with hemodialysis and plasmapheresis.

Preservation of the pancreatic β-cell population is required for the development of therapies for diabetes, which is caused by a decrease in β-cells. Here, we demonstrate the antidiabetic effects of substance P (SP) in type 1 diabetes (T1D) mice induced with streptozotocin. SP enhanced the compensatory proliferation of β-cells in order to restore β-cells in response to acute injury induced by a single high-dose of streptozotocin. However, SP affected neither the basal proliferation of β-cells nor their apoptosis...
