Background: Oxidative stress is supposed to be implicated in the pathogenesis of several diseases which are connected with increased formation of reactive oxygen and nitrogen species (RONS). Oxidative stress could play an important role in the pathogenesis of inflammation and sepsis, acute and chronic pancreatitis or in the development of cancer. Organisms are protected against RONS from antioxidant system that is composed of antioxidant enzymes and non-enzymatic antioxidants. To the most important antioxidant enzymes belong superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase, glutathione reductase and paraoxonase (PON). The aim of this Doctoral Thesis was to investigate the behaviour of three of these antioxidant enzymes - CuZnSOD, CAT and PON1 in different pathophysiological states. Materials and methods: The activities of CuZnSOD, CAT and PON1 were measured in six different pathophysiological states. Forty patients with metabolic syndrome (MetS), 35 women with depressive disorder (DD), 30 septic patients (SP), 50 patients with pancreatic cancer (PC), 50 patients with chronic pancreatitis (CP) and 13 patients with acute pancreatitis (AP) were included in different studies together with sex- and age-matched healthy controls (CON). Patients with AP and SP were observed in the course...
