Emotional stress was stimulated by placing rats in a tight cage (moderate stress) or fixing them rigidly on a bench (marked stress) for 1 hour. In moderate emotional stress, the coronary fraction of cardiac output and effective myocardial blood supply declined considerably. Marked emotional stress caused a similar reduction in the cardiac output coronary(More)
The main characteristics of systemic hemodynamics and relative changes in the blood content, blood flow and uptake of intravenous 86Rb in several tens of organs, tissues and parts of the body were examined in rat experiments 6 days after ligation of the common bile duct. This made it possible to appraise the resistive, capacitance and capillary constituents(More)
Regional changes of circulation after injection of pirroxan, obsidan and ornid depended on functional state of rats. The differences were significant in systemic hemodynamic and regional changes of resistive, transcapillary exchange and the blood volume function of the circulation.
A preliminary pharmacological desympathization (pirroxan, obzidan, ornid) decreased blood pressure, heart rate, cardiac output, and increased total vascular resistance in immobilized rats. The fraction of cardiac output decreased in lung (bronchial blood flow), liver and myocardium and increased in other organs and tissues. Relative blood supply increased(More)
