[Effect of colostrum polypeptide on structure and lipid peroxidation in liver nuclei of rats late after gamma-irradiation].

: Rats were irradiated by 8Gr in a doze power of 2.33 R per second. A portion of animals were injected subcutaneously with a cow colostrum polypeptide (CP) in a doze of 1 mg per g of body weight before the irradiation and daily after the irradiation during 4 days. In irradiated rat liver nuclei injected with CP the lipid peroxide oxidation was restored. At 90th day after the irradiation the production of dienes and dieneketones in liver nuclei oscillated in normal limits. The structure and cytochrome-c-oxidase activity of the nuclei was restored to 60-90th day after the irradiation.
