Abstract:
Oxidative stress has long been recognized to play an important role in the pathogenesis of chronic obstructive pulmonary disease (COPD) and aging, initiating oxidative damage of biomolecules. In this study the development of imbalances in the system of lipid peroxidation and increase the level of the marker of oxidative damage to DNA - 8-hydroxy-deoxyguanosine (8-ОНdG) in patients with COPD and healthy individuals. Evaluation of the relationship between the parameters of the system of lipid peroxidation and the level of 8-ОНdG allowed to drill down to different oxidative mechanisms in the pathogenesis of COPD in patients of middle or old age.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
