Content of adrenaline, noradrenaline, dopamine and normetanephrine was estimated by means of trihydroxyindole method in samples of brain and its hypothalamic part from intact, adrenal- and sympathectomized rats within 15 min, 24 and 72 hrs after hemorrhagic stress (3% blood of body weight within 20 min). Stable increase in dopamine content was observed in brain at all the periods studied. Alterations in the noradrenaline turnover in central nervous system were related to the state of peripheral sympathoadrenal system at early posthemorrhagic steps; the phenomenon was not found at the later periods after stress.
