[Catecholamines and plasma renin activity of the Koletskii strain of rats under emotional stress].
Koletsky rats differ from Wistar rats by a significantly higher initial arterial blood pressure (AP) and by the increased plasma renin activity. The plasma noradrenaline level in control obese Koletsky rats is also significantly higher than that in Wister rats. There are also considerable differences in the time course of changes in the tests characteristics of rats of both lines during immobilization. AP in Koletsky rats decreases within 120 min of immobilization while in Wistar rats it remains virtually unchanged. Within the first minutes of immobilization plasma renin activity rises, and attains a significantly higher level in Koletsky rats than in Wistar rats. In the later periods of immobilization the strains showed differences in the blood catecholamine content, particularly in that of noradrenaline, a higher content being found in Koletsky rats.
