The function of enzymes for the antioxidative protection of the bone marrow cells in rats during irradiation, bone fracture and combined radiation injury

The activity of superoxide dismutase, glutathione peroxidase, glutathione reductase and glutathione: dehydroascorbate oxidoreductase is lower in the bone marrow than in the liver. The changes in the cellular antioxidative enzymatic system during leg bones fracture and X-ray irradiation are more pronounced in the rat bone marrow, as compared to the liver. The data obtained are in keeping with selective bone-marrow radiosensitivity and with the effect of exogenous superoxide dismutase and glutathione as radioprotectors.
