Adrenal Cortical Steroid Levels in Peripheral Blood of Intact and Adrenalectomized Parabiotic and Single Rats

Abstract
Concentrations of alpha-ketol steroids in peripheral blood of intact and adrenalectomized parabiotic and single rats were estimated. The corticoid levels were found lower in adrenalectomized than in intact rats whether parabiotic or single. The ratios of blood steroid concentrations of intact and adrenalectomized parabionts indicate an uneven distribution of adrenal steroids between the 2 partners. The significance of the transmission of adrenal steroids through the parabiotic anastomosis was discussed.
