[Reaction of specific cell populations of hypothalamic paraventricular nuclei of the rat to carbohydrate loading and fasting]. / Reaktsiia otdel'nykh kletochnykh populiatsii paraventrikuliarnykh iader gipotalamusa krys na uglevodnuiu nagruzku i golodanie.

The structural correlates of the cell responses in subnuclei of the hypothalamic paraventricular nuclei (PVN) in fasting and carbohydrate loaded adult male rats were studied using light microscopic morphometric methods. The data obtained revealed difference in responsiveness of the subnuclei studied to alternative shifts in the carbohydrate homeostasis: histophysiological features in five of ten cell-divisions, distinguished in the rat RVN, demonstrated their dependence on impaired carbohydrate homeostasis.
