title: [Mechanism of hyocorticosteronemia action of Strongyloides ratti in the rat].
abstract: In order to explain the hypocorticosteronemia which establishes itself in rats with Strongyloides ratti parasites, we are proceeding with a functional exploration of the hypothalamo-hypophyso-corticosurrenal axis in experimentally infested rodents. The adreno-cortico-tropic-hormone test (A.C.T.H.), stress to ether and the Lysin-8-Vasopressin and Metopirone tests lead to concordant results: -- the hypothalamo-pituitary-corticosurrenal present a functional integrity which allows it to react normally to direct stimulation or to feed-back; -- the deficiency seems to relate to the hypothalamic secretion of the cortico-releasing factor; -- the cause would stem from an inhibition of the nervous mechanism which regulates this neurosecretion.
