[Age-related dynamics of the response of the hypothalamo-hypophyseal neurosecretory system in rats to a change in corticoid levels of the blood].
Hypothalamic vasopressin- and corticoliberinergic neurosecretory cells are able to change their activity after true or shame adrenalectomy in respect to the level of corticoids even in 10-day old rats. Vasopressin and corticoliberin accumulate in the nerve fiber terminals of the median eminence external zone a few days after surgery in young rats as opposed to the accumulation within 2-3 weeks usually observed in adults. The underdifferentiation of neurovascular relations in the neurohaemal area seems to be the reason for [areactivity] of the hypothalamo-hypophyseal system in young rats.
