title: [Morpho-functional status of large-cell hypothalamic nuclei following chronic exposure to wide-range electromagnetic impulses].
abstract: In a experiment with white nubilous male rats the morphofuntional state of secretory neurons (SN) of the large-cell hypothalamic nuclei (LCHN) was evaluated with the morphological, morphometric and statistical methods following electromagnetic exposure (500, 100 and 50 impulses once a week) inducing in the animal body the averaged current densities of 1.5 kA/m2. It was stated that 100 EMI a week called forth opposite LCHN reactions, that is suppression of synthesis and elimination of SN neuro-secret in supraoptic nuclei and their activation in the paraventricular nuclei. LCHN reaction to the other frequencies of EM impulses was uniform and included rearrangement of both neurosecretory centers for a lower functional activity. Decrease in the number of effectively functioning SN due to the EM exposure may point to a dead-aptive effect of this factor.
