Cardiovascular hormonal effects of circulating norepinephrine.

The hormonal effects of circulating norepinephrine (NE) were evaluated with two-step NE infusion studies in normal volunteers. At an infusion rate that increased plasma NE 2.5-fold (approximately equivalent to the change from supine to upright posture), there were small but consistent increases in diastolic pressure (+5 mm Hg) and plasma renin activity (+13%). At the high extreme of the physiol...

Hormonal influences on cardiovascular norepinephrine transporter responses in healthy women.

Gender differences in human cardiovascular norepinephrine transporter function may be mediated through female sex hormones. We studied 16 healthy eumenorrheic women (25+/-1 years) during the early follicular phase (day 5+/-0) and midluteal phase (day 22+/-0) of the menstrual cycle. In a randomized, crossover, double-blind fashion, subjects ingested 8 mg of the selective norepinephrine transport...

Cardiovascular Effects of Sustained Norepinephrine Infusions

• Norepinephrine (NE) administration has been implicated in the production of morphologic changes in various organs and tissues. Blacket, et al., in 1950, in a paper on the effects of prolonged infusion of NE on arterial pressure of rabbits, commented that these rabbits became ill, listless and did not eat, and on gross examination showed dilatation of the terminal large gut. Boughton and Somme...

Comparative Cardiovascular Effects of Tyramine, Ephedrine, and Norepinephrine in Man.

• The observation that tissues depleted of norepinephrine no longer respond normally to certain sympathomimetic amines" led Burn and Rand to hypothesize that these amines exert their effect by releasing norepinephrine from storage sites in the postganglionic adrenergic nerve endings. On the basis of their effect on denervated or reserpine-pretreated tissues, the sympathomimetic amines have been...

Effects of Steroids on Cardiovascular Responses to Norepinephrine

Cardiovascular responses to graded iv infusions of norepinephrine were observed in 24 dogs that had been treated for 1 week with either placebo, dexamethasone, or deoxycorticosterone. Eight dogs served as control and received daily iv injections of placebo; eight dogs received the mineralocorticoid, deoxycorticosterone; and eight received the glucocorticoid, dexamethasone. The three groups did ...
