The state of pro-oxidant-antioxidant homeostasis in guinea pigs exposed to whole-body fractionated X irradiation (5 fractions of 0.2 Gy at a 24 hr interval, up to total dose of 1.0 Gy, at a dose rate of 0.425 R/min) and a possibility of its disturbance correction with the complex of vitamins C, E and P was studied. Accumulation of primary and secondary lipid peroxidation products, decrease of the ascorbic acid content, increase of the content of its oxidized forms (dehydroascorbic acid and diketogulonic acid) in radiosensitive (spleen and small intestine) and radioresistant organs were found. Antioxidant complex administration reduced the disturbances of pro-oxidant-antioxidant homeostasis, but did not provide complete normalization.
