Abstract
The rate of hydroxylation of androgens was shown to be significantly reduced by γ-ray irradiation in doses of over 600 R. The rate of hydroxylation of estrogens showed little change. During irradiation under these conditions the content of cytochrome P-450 in the rat liver microsomes fell. The decrease in the rate of hydroxylation of steroid hormones by rat liver microsomes under the influence of whole-body γ-ray irradiation evidently depends on quantitative changes in cytochrome P-450.
