[The effect of electrostimulation of the hypothalamic mamillary nuclei on the vascular permeability of the skin in intact and capsaicin-pretreated rats].

Electrical stimulation of the hypothalamic mamillary nuclei increased the permeability of the skin blood vessels in rats. Pretreatment of the animals with capsaicin prevented the effect. The mamillary nuclei seem to take part in the central mechanisms of efferent function of the capsaicin-sensitive neurons.
