Adrenal Size and function after irradiation with 131I-6 beta-Iodocholesterol in rabbits.
Administration of high doses of 131I-6 beta-iodocholesterol to rabbits is followed by marked size reduction of the adrenal glands with concomitant changes of the histological structure and with a decrease of serum cortisol. Stimulation of 131I-6 beta-iodocholesterol uptake into the adrenals by additional administration of ACTH had only a minor additional effect on adrenal weight. However, with further accumulation of labeled cholesterol in the adrenals the radioactivity was reduced in blood urine, and the ovaries.
