[Free radicals and metal paramagnetic ions of the tissues of rats exposed to gamma irradiation and hormones].
It was shown that gamma-radiation (8-16 Gy) did not influence the number of paramagnetic centers of hemal (g = 2.42, g = 2.25) and nonhemal (g = 1.94) iron of rat tissues: free radicals were significantly reduced 5 min after 16 Gy irradiation. The combined effect of gamma-radiation (8 Gy) and ubiquinone-9 decreased the number of the above-mentioned ESR signals after 48 h. The number of free radicals in the rat liver, kidneys and spleen was almost twice reduced 28 days following castration. The administration of methyl testosterone increased the free radical amount in the heart and was ineffective in other rat organs.
