| Popis: | We studied the functionality of the antioxidant system in laboratory rat cardiac muscle cells and blood under psycho-emotional stress. It was found that 40-day isolation and violation of diurnal cycle among the animals were accompanied by the intensification of lipid per oxidation process shown by a rise in the quantity of one of the primary and final products of this process - diene conjugates and thiobarbituric acid active compounds, including malonedialdehydes and marked with a reduced activity of antioxidant system enzymes, such as catalase and superoxide dismutase activity. Based on the results, we pro-posed that psychological stress is one of the factors contributing to the development of various cardiac diseases. |
