title: [Changes in rat hypothalamo-neurohypophyseal system after repeated ethanol administration].
abstract: The histochemical, immunohistological and histoenzymatic study of the hypothalamo-neurohypophysial system of the rat shows that chronic ethanol administration induces: a temporary blockage of vasopressin synthesis, a vasoconstriction of the neurohypophysial capillaries, a dendritic storage of immunoreactive vasopressin. In our experimental conditions, a long ethanol treatment disturbs the balance between vasopressin synthesis and release.
