[Influence of the ventro-medial nuclei of the hypothalamus on adrenocortical function under conditions of muscular stress].

After repeated stimulation of hypothalamic ventro-medial nuclei with square electrical stimuli, swimming during 20 min with a load equal to 10% of body weight increases the weight of adrenal glands, the width of the cortical layer, and the width of glomerular fascicular, and reticular zones, decreasing at the same time the ascrobinic acid and cholesterin contents in the gland as well as the eosinophil content in the peripheral blood. After lesion of the ventro-medial nuclei, the same effects of the swimming are less obvious than in normal, with no stimulation whatever.
