Abstract:
The effect of vasoactive intestinal polypeptide on vaginal blood flow was investigated in postmenopausal women. In women who were receiving hormonal replacement therapy the vasodilatory response induced by vasoactive intestinal polypeptide was identical to that of young women, whereas in postmenopausal women who were receiving no replacement therapy, the response induced by vasoactive intestinal polypeptide was absent. Plasma levels of vasoactive intestinal polypeptide and systemic cardiovascular effects were identical in the two groups.

Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
