title: [Effect of ionizing radiation of low intensity on activity of catalase and superoxide dismutase of Hormoconis resinae].
abstract: The level of activity of antioxidant enzymes catalase and superoxide dismutase and influence of ionizing radiation of low intensity on their activity in two strains of Hormoconis resinae were investigated. One of the strains was isolated from the object Shelter showing radio-adaptation properties and another was the control one. It was shown, that the strain which showed radio-adaptation properties had higher initial level of endocellular catalase activity than the control one in both growth phases, and that of superoxide dismutase activity--in a logarithmic phase only. It was established, that essential (manyfold) changes occurred under radiation effect in activities of superoxide dismutase and catalase of studied fungi, which depended on the growth phase and availability of radio-adaptation properties in the investigated strains.
