Abstract | OBJECTIVE: DESIGN AND SETTING: MEASUREMENTS AND RESULTS:
Intraperitoneal injection of cerulein in mice resulted in severe, acute pancreatitis characterised by oedema, neutrophil infiltration, tissue haemorrhage and necrosis and elevated serum levels of amylase and lipase. Infiltration of pancreatic and lung tissue with neutrophils (measured as increase in myeloperoxidase activity) was associated with enhanced lipid peroxidation (increased tissue levels of malondialdehyde). Immunohistochemical examination demonstrated a marked increase in immunoreactivity for nitrotyrosine, iNOS and PARS in the pancreas and lung of cerulein-treated mice. In contrast, pre-treatment with calpain I inhibitor markedly reduced: the degree of pancreas and lung injury; upregulation/expression of ICAM-1; staining for iNOS, nitrotyrosine and PARS; and lipid peroxidation. Additionally, calpain I inhibitor treatment significantly prevented the activation of NF-kappaB as suggested by the inhibition of IkappaB-alpha; degradation in the pancreas tissues after cerulein administration.
