摘要
Background: Acute pancreatitis is a serious condition with multi-factorial etiology. The negative impact of acute pancreatitis on the exocrine pancreatic function is well documented; however, its impact on the endocrine function needs more elucidation. Our study aimed to investigate the effect of Nano-Selenium (Nano-Se) on both pancreatic functions in acute pancreatitis. Methods: L-arginine induced acute pancreatitis in rats was used as a model. Fifty adult male albino rats were separated into groups: 1- control group (C), 2- C+ Nano-Se, 3-acute pancreatitis group (AP) and 4- AP+ Nano-Se. Nano-Se was administered before induction of acute pancreatitis. Serum levels of amylase, lipase, selenium, glucose, insulin and interleukin-1 beta (IL-1 beta) were measured. Homeostatic model assessment of beta cell function (HOMA-beta) was also calculated. Oxidative stress markers, selenium content and the anti-apoptotic factor, B-cell leukemia/lymphoma-2 (Bcl-2) were assayed in pancreatic tissue along with immuno-expression of nuclear transcription factor-kappa B (NF-kappa B). Results: Acute pancreatitis negatively affected both pancreatic functions. Nano-Se administration lessened the developed pancreatic injury and improved both pancreatic functions. Conclusion: Nano-Se could improve the deteriorated pancreatic functions in acute pancreatitis via its anti-inflammatory, antioxidant and pro-apoptotic actions. Thus, it may be used in prevention of acute pancreatitis and the associated hyperglycemia in vulnerable individuals such as patients undergoing endoscopic retrograde cholangio-pancreatography.
