Department of Physiology, Karolinska Institute, Stockholm, Sweden.

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.

UI	MeSH Term	Description	Entries
D010233	Paraganglia, Chromaffin	Small bodies containing chromaffin cells occurring outside of the adrenal medulla, most commonly near the sympathetic ganglia and in organs such as the kidney, liver, heart and gonads.	Chromaffin Paraganglia
D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002838	Chromaffin System	The cells of the body which stain with chromium salts. They occur along the sympathetic nerves, in the adrenal gland, and in various other organs.

D000311	Adrenal Glands	A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
