    Abstract:
    The levels of serum monosaccharides (SMO) and hexuronic acids (SHA) were measured in subjects without any metabolic or endocrine disease after a short-time administration of cortisol, dexamethasone and ACTH. The effects of the three hormones were evaluated in regard to the urinary excretion of free cortisol and cortisone at basal conditions. In thirteen subjects a significant increase of SMO during cortisol treatment was registered after 24 hours. A distinct difference in the response of SMO to cortisol treatment was observed in patients with normal or increased cortisol excretion, respectively. In the subjects with high urinary free corticoids a peak of SMO occurred soon after 4 hours after cortisol administration, in the next 48 hours no tendency of return towards basal levels was observed. In the subjects with normal urinary free cortisol excretion only a slight increment was seen after 24 hours. Soon after 4 hours in eight subjects dexamethasone administration resulted in an increase of SMO without regard to the excretion of urinary free corticoids. The highest values were obtained after 28 hours of dexamethasone treatment. Ten hours after cessation of dexamethasone the levels of SMO reached the basal values. In the study in which ACTH was administered, an increment of SMO was registered only in the first four hours. In the group of subjects treated with ACTH a slight difference between subjects with normal and increased corticoid excretion was seen. The levels of SHA successively increased after the administration of all three hormones, without regard to the basal excretion of urinary free corticoids. This increase persisted also 10 hours after cessation of cortisol and dexamethasone, and 40 hours after the last dosis of ACTH, respectively. The possibility of an altered metabolism of glucose through the glucuronate pathway under conditions of glucocorticoid excess is discussed.
