Correlation between the Chemiluminescent Activity of Neutrophilic Granulocytes and the Lipid Peroxidation-Antioxidant Defense System in Gastric Cancer Associated with Infection.

Aim: To study the processes of lipid peroxidation and the activity of antioxidant defense enzymes depending on the chemiluminescent activity of neutrophilic granulocytes in patients with gastric cancer associated with infection, depending on the stage.

Materials And Methods: A total of 39 patients with stage I-II gastric cancer and 30 patients with stage III-IV gastric cancer were examined. A study of the chemiluminescent activity of neutrophilic granulocytes was carried out and the parameters of the lipid peroxidation system and antioxidant protection in plasma were determined using the spectrophotometric method.

The Role of Immunoglobulin G (IgG), IgA and IgE-Antibodies against in the Development of Oxidative Stress in Patients with Chronic Gastritis.

Aim: To study the predominant serum responses (antibodies IgG, IgA, IgE) against H. pylori in relation to the indicators of the system “lipid peroxidation−antioxidant system” in various pathogenetic variants of chronic gastritis (CG). Materials and Methods: Sixty patients with CG, 33 patients with chronic atrophic gastritis (CAG) and 31 patients with chronic allergic gastritis (CALG) were examined.

Dynamics of Oxidative Stress in -Positive Patients with Atrophic Body Gastritis and Various Stages of Gastric Cancer.

Gastric cancer is a global health problem. The pathogenesis of this disease remains unclear. This study included 198 (+) men aged 45 to 60 years old.
