title: [The influence, in normal subjects, of a high-protein normocaloric diet on the response of cortisol, ACTH, GH, and PRL to insulin hypoglycemia].
abstract: A protein rich diet causes a remarkable increment of plasma cortisol, corticotropin and somatotropin concentration, but does not modify the plasma prolactin level; this diet, moreover, is followed by a more vivacious response to the Lysin-8-Vasopressin test. In 10 healthy voluntary subjects we have studied the hormonal behaviour during the insulin-induced hypoglycemia test in course of equilibrated diet and after 15 days of protein-rich diet. In these two experimental conditions the insulin-induced hypoglycemia test has promoted a similar increment of the four hormones. The different behaviour between the two tests -Lysin-8-Vasopressin and insulin-induced hypoglycemia- indicates that the increased hormonal levels which follow a protein-rich diet are not provoked by a generic stress effect, but by a direct stimulation of the hypothalamo-hypophyseal structures.
