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

infection, regardless of the stage of the disease, an increase in lipid peroxidation processes with activation of antioxidant defense enzymes was detected. At the same time, there were no statistically significant differences between the indicators of the system lipid peroxidation-antioxidant protection depending on the stage of gastric cancer and the chemiluminescent activity of neutrophilic granulocytes, which likely indicates that all reactive oxygen species produced by neutrophilic granulocytes in the respiratory burst are consumed locally, minimally affecting the development of oxidative stress in the blood plasma.
