Using the apparatus "POOS-I" (a device for measuring the reflecting power) the author carried out microspectrophotometric determination of the DNA content in the lymphoid tissue of mice following gamma-irradiation and transplantation of the syngenic and allogenic bone marrow. An amount of DNA was expressed as a relative value representing optical density of histological sections stained after Feulgenmthis method has proved to be a sensitive objective test for evaluation of the extent of lesion and restoration of the lymphoid tissuek0
