Popis: The cortisol secretion rate and the response to ACTH stimulation and to methopyrapone have been studied in high altitude native residents in comparison with a similar group of men living at sea level. No differences were found in the cortisol secretion rate, in the stimulation with 20 U of ACTH and in the response to methopyrapone administration. However, with 1 U of ACTH the high altitude group had a lower excretion of 17-ketosteroids and 17-hydroxycorticosteroids. In view of these results it may be postulated that high altitude natives need a greater ACTH production to maintain a cortisol secretion rate similar to the one observed in the sea level group. A possible explanation for the lower response to 1 U of ACTH in high altitude natives, but a normal one to 20 U of ACTH, is offered.
