[Character of metabolism and regulating role of cholinoreactive tissue systems during hypercapnia, hypoxia and cooling].

The content of the free fatty acids, ketone bodies, total glycogen, glucose, adrenaline and noradrenaline and morpho-histochemical picture of the tissues of neuro-endocrinal system (hypophysis and adrenal) in the brain, heart, liver, skeletal muscles and blood of the white non-linear rats, were studied 2-3 min adaptation to complex atmosphere changes: gradual increase of the CO2, decrease of the O2, and cooling (in the condition of deep hypothermia the rectal temperature was--RT--19.1 +/- 0.1 degrees C). The same parameters were studied in 48 hrs after the same training (at normothermia) and in 2-3 min. after the same repeated training in 48 hrs after the first one, at RT--20.2 +/- 0.1 degrees C. The fluctuating character of the metabolism and of the regulating systems was shown.
