[The neuronal characteristics of the subnuclei of the paraventricular hypothalamic nucleus in rats (based on the data from morphometric and informational analyses)].
Subnuclei of the paraventricular nucleus (PVN) of the hypothalamus were studied in chronic experiments in 60 male Wistar rats (3 groups of animals) under normal conditions and under the influence of intensive and moderate regiments of hypoxic trainings. The division of macro- and micro-cellular populations of neurons of PVN is justified not only due to the peculiarity of the topographo-anatomical arrangement of them in the nucleus and the neuroanatomical relations but also due to a difference of their morphometrical (volumes of the cells, their nuclei, cytoplasm, nucleo-cytoplasmic coefficient) and informative characteristics (relative entropy and informative excess). The use of this approach in the assessment of the functional state of neurosecretory cells when compared with the change of organism resistance allows more complete assessment of the level of morphofunctional activity of neurons of subnuclei ot PVN and of their adaptation reserve which is important from the viewpoint of prognosis of the possibility of ther participation in protective-adaptational and compensatory reactions.
