title: [Effect of extirpation of the cervical sympathetic ganglia on the postnatal development of the paraventricular nucleus of the rat hypothalamus].
abstract: The importance of trophico-adaptive influences of the sympathetic nervous system for the postnatal hypothalamus development was shown experimentally on rats. Using kario-cytometric method it was found that cervical ganglia extirpation was followed by retarded ontogenetic development of the neurosecretory cells of the paraventricular nucleus, and also by blood vessel changes. The sympathectomy effect coincided with the beginning of an intensive cytoplasm growth in the paraventricular nucleus cells. Sympathectomy proved to be more effective in ratlings than in adult animals.
