... role in drug-induced anorexia caused by amphetamines. It is also the most sensitive site in the hypothalamic monoaminergic system that involves dopamine (DA) and epinephrine (EPI). DA antagonist, stereotaxically placed in this site, can stimulate feeding, and specific injections of DA or EPI can result...

...Seon H. Shin; Ruth E. Barton Prolactin release from primary cultured pituitary cells was investigated using a dynamic perifusion system. Although epinephrine (1 µmol/l) produced an elevation in the mean value of the prolactin concentration at the onset of the perifusion, the elevation...

Holst The effects of epinephrine and of splanchnic nerve activation on adrenocortical androstenedione release were studied in intact isolated perfused...

... injection of the H 1 receptor antagonist ranitidine (1 × 10 –8 , 5 × 10 –8 mol) did not suppress the hyperglycemia induced by PGF 2 α. The concomitant injection of 5 × 10 –8 mol diphenhydramine or pyrilamine with 50 µg PGF 2 α significantly suppressed the increase in plasma epinephrine induced by PGF 2 α...

...Susan L. Stoddard; Valerie K. Bergdall Seventy-five sites were electrically stimulated within the preoptic and hypothalamic areas of anesthetized cats (n = 16). Adrenolumbar venous blood flow, secretion of epinephrine and norepinephrine, heart rate and mean arterial blood pressure were measured...

... hyperglycemia associated with an increase of epinephrine and glucagon in anesthetized fed rats. To evaluate the relative contribution of these glucoregulatory hormones and the nervous system to the net hyperglycemic response, we unilaterally injected neostigmine (5 × 10 –8 mol) into the dorsal hippocampus...

... phenoxybenzamine in a medium containing 1 mmol/l epinephrine, the effect of the phenoxybenzamine was also eliminated, suggesting that a sufficient amount of D 2 receptor-epinephrine complex was formed to protect the receptor from inactivation. The hormone release in response to a secretagogue depends on its...

... ventricle of rats, and the concentrations of hepatic venous plasma glucose, immunoreactive glucagon, immunoreactive insulin, epinephrine, and norepinephrine, were measured. Four groups of animals were evaluated: (1) intact rats; (2) rats receiving an infusion of somatostatin with insulin via the femoral...

...Guido Pesce; Viviane Guillaume; Daniela Jezova; Maxime Faudon; Michel Grino; Charles Oliver This study was performed to determine if epinephrine (EPI) present in hypophysial portal blood has a peripheral or a central origin. Pituitary stalk and femoral arterial EPI plasma levels were simultaneously...

A significant increase in plasma PRL levels was shown in grafted (22 ± 2 µg/1) when compared to control rats (6 ± 0.3 µg/1), together with a significant increase in plasma norepinephrine (NE) (4.2 ± 1.1 µg/1 vs. 1.7 ± 0.7 µg/1) and epinephrine (E) (2.9 ± 0.6 µg/1 vs. 1.6 ± 0.2 µg/1...

In intact or sham-operated rats, immobilization caused a prompt increase of circulating norepinephrine, epinephrine (EPI), corticosterone and of immunoreactive adrenocorticotropic hormone (ACTHi), α-melanocyte-stimulating hormone (α-MSHi) and β-endorphin (β-ENDi). Peak levels of pituitary hormones were...
