Oxidative stress in the lung tissue--sources of reactive oxygen species and antioxidant defence.
نویسندگان
چکیده
Reactive oxygen species are oxygen-based molecules readily reacting with various compounds. It is already known that they play significant role in many physiological as well as pathological body processes. The aim of our review is to briefly summarize our knowledge of possible ROS sources in the lung tissue.

Abstract During normal cellular activities Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS) are produced. In addition to beneficial functions they play a critical role in cell death and prevent apoptosis. Every cell is equipped with an extensive antioxidant defense system to combat the excessive production of active radicals. Oxidative stress occurs with destruction of cellu...
متن کاملThe effect of phytochemical compounds on indicators of oxidative stress, inflammation and skeletal muscle damage caused by physical activity
Physical activities are associated with increased production of reactive oxygen species. The production of reactive oxygen species is dependent of the intensity, duration and type of activity. Although the physiological amounts of reactive oxygen species are necessary to regulate cell reactions, their excessive production can cause numerous damages to the structure and function of cells and wea...
متن کاملOxidative Stress Implications in Various Lung Diseases. Focusing on One Lung Ventilation
OXIDATIVE STRESS IMPLICATIONS IN VARIOUS LUNG DISEASES. FOCUSING ON ONE LUNG VENTILATION (Abstract): One the most intriguing biomedical fact nowadays is that many of the existent diseases exhibit a certain molecular component expressed through oxidative damage. In this way, it seems also that lung diseases have an oxidative stress component which is clearly shown by impairment in oxidant/antiox...
متن کاملFormation of reactive species and induction of antioxidant defence systems in polar and temperate marine invertebrates and fish.
High oxygen solubility at cold-water temperature is frequently considered to be responsible for an apparently elevated level of antioxidant protection in marine ectotherms from polar environments. However, tissue oxidative stress is in most cases a function of elevated or variable pO2, rather than of an elevated tissue oxygen concentration. This review summarizes current knowledge on pro- and a...

Objective(s):Atherosclerosis is chronic inflammatory process triggered by oxidative stress. Oxidative stress can increase hydrogen peroxide (H2O2)level, which induce atherosclerosis through the processes such as formation of perivascular adipose tissue (PVAT), foam cells, and atherosclerotic plaque. Antioxidant is needed to control negative effects of oxidative stress. One source of antioxidant...
