title: Postnatal development of catecholamines and response to hypoxia in adrenals and paraganglia of rabbits.
abstract: The postnatal development of catecholamine levels in adrenals and paraganglia in newborn rabbits has been analyzed. At birth, the dominant catecholamine was noradrenaline, contributing 66% of the total catecholamine pool at day 1, 55% of which came from the paraganglia. There was a rapid postnatal increase of adrenaline, which constituted 67% of the total catecholamines at day 6 and 97% in the adult. After hypoxia at day 1, the noradrenaline levels decreased in paraganglia but not in adrenals, while adrenaline levels did not significantly change in either organ.
