    Abstract:
    The state of hypothalamic oxytocin-synthesizing system in Wistar rats were investigating. The morphometric measurements and immunocytochemical detection of oxytocin-containing cells was used for determining of the functional state of supraoptic nucleus, anterior and posterior-medialis magnocellular subdivisions of paraventricular nucleus. It was established intermittent hypoxic training exert positive influence on rats with experimental diabetes mellitus. This effects depending on increasing synthesis and secretion of hypothalamic oxytocin. Intermittent hypoxic training elevate contents of immunoreactive oxytocin without changing morphometric characteristics in neurons of supraoptic and paraventricular nuclei and median eminence of hypothalamus. In comparison oxytocin contents in these neurons elevade less significance in diabetic rats, but it was observed increasing of nucleolus volume in hypothalamic oxytocin-synthesizing neurons. Intermittent hypoxic training of diabetic rats stimulate more significance elevating oxytocin contents in hypothalamic neurons and median eminence that evidence high level activity of hypothalamic oxytocin-synthesizing system.
