[Analytical and analogical study of a model of the adrenal-postpituitary function (author's transl)]. / Etude analytique et analogique d'un modèle de la fonction surréno-post-hypophysaire

After an analyitical study of mathematical models connected with osmotic or volemic regulations, and the mention of its contribution to the therapeutic act, the authors approach the stimulation, by the mean of an analogical computer, of the complete and non-linear model which associates both types of regulation. So it is possible to attempt to determine the level of adrenal and vasopressin actions according to: 1 degree the sum of the agonistic effects and the difference of their antagonistic effects; 2 degrees the perturbations brought to the system; 3 degrees the parametric values of the model. Theoretical and empirical curves seem to be in favour of such a formulation.
