Systemic vascular autoregulation amplifies pressor responses to vasoconstrictor agents

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1989
Experiments were performed in seven conscious dogs to evaluate the contribution of total systemic autoregulation to the increase in mean arterial pressure (MAP) produced by the intravenous administration of pressor agents. Each dog was instrumented for the measurement of aortic pressure, central venous pressure, and cardiac output, and all dogs ...

femoral arterial responses to vasoconstrictor and vasodilator agents in endotoxin shock

Life Sciences, 1994
The hypothesis for this study is that the decreased arterial response to catecholamines may be due to the effect of endotoxemia on vessel tone. One control ring was taken from one femoral artery of a Wistar rat and after endotoxin (ENDT) infusion (i.v. 6 mg/kg-1 hr.), one ring was removed from the contralateral artery.

Regional autoregulatory responses during infusion of vasoconstrictor agents in conscious dogs

American Journal of Physiology-Heart and Circulatory Physiology, 1990
We investigated pressure-dependent autoregulatory responses in mesenteric, iliac, and renal vascular beds of conscious dogs during intravenous infusion of angiotensin II, phenylephrine, or arginine vasopressin at rates which increased arterial pressure by 20-40 mmHg.

EFFICACY OF VASOCONSTRICTOR AGENTS IN THE OBSTRUCTED NOSE: A QUANTITATIVE EVALUATION

Archives of Otolaryngology - Head and Neck Surgery, 1942
During the past decade there has been a considerable difference of opinion as to the comparative efficiency of ephedrine and its synthetic derivatives in the treatment of nasal obstruction. Previous attempts to determine their specific action in the obstructed nose have not provided reliable data, largely because of the limitations of the methods ...

[Toxicity tests in vasoconstrictor agents added to local anesthetics].

Deutsche zahnarztliche Zeitschrift, 1976
The toxicities of adrenalin, nor-adrenalin and vasopressin derivatives were compared on the basis of animal tests, among others. The adrenalin additive is rejected.
