title: [Changes in the catecholamine content in adrenaline-synthetizing structures of the medulla oblongata in rats with different reactions to long-term immobilization].
abstract: Substantial individual variations of some indices studied were found as a result of comparing catecholamine changes after 6.5-hours' immobilization at A1 and A2 regions of Wistar rat oblongata and in the solitary tract nucleus with abnormal arterial blood pressure and stomach mucosa. The most pronounced catecholamine alterations, manifesting in epinephrine level fall after immobilization, were seen at A1 region. The degree of epinephrine level lowering at A1 region does not correlate with peculiarities of the changed blood pressure or stomach mucosa. It is suggested that A1 region participates in organization of the total component of stress reaction.
