The aim of this study was to investigate the impact of L-arginine (nitric oxide synthase substrate), L-NG-nitro-L-arginine (nitric oxide synthase inhibitor), and heparin on the pancreas microcirculation, serum IL-6 level and microscopic alterations of the pancreas in acute pancreatitis in rats. Acute pancreatitis was induced by 4 i.p. injections of cerulein (15mg/kg). Microcirculatory values were measured by means of laser Doppler flowmetry 5 h after the first cerulein injection. Remarkable histopathological changes in the pancreas, including parenchymal necrosis, an elevation of serum IL-6 level, and a significant drop of pancreatic capillary perfusion was observed in rats with nitric oxide synthase inhibition. L-arginine improved the pancreatic microcirculation but worsened the microscopic alterations within the pancreas. Heparin had a beneficial effect on the microcirculatory values, serum IL-6 concentration, and morphologic changes. Authors conclude that inhibition of nitric oxide synthase aggravates acute pancreatitis. L-arginine treatment improves pancreatic perfusion but potentiates morphological alterations. Heparin, improving the microcirculation and inflammatory changes within the pancreatic gland, may be considered as a promising therapeutic agent in acute pancreatitis. |
