...Wang-Ni Tian; Emir Duzic; Richard C. Deth The receptor-coupling efficiency for epinephrine (EPI) stimulated heterotrimeric G protein activation was studied at the G protein level in membranes prepared from PC 12 cells expressing cloned α 2D -adrenergic receptors (α 2D -AR). After pretreatment...

... action, and sustained elevations in [Ca 2+ ] i may be involved in the initiation of hepatocellular damage. To evaluate the possible involvement of intracellular Ca 2+ and/or cAMP, we investigated effects of cocaine and lidocaine on basal, epinephrine and dibutyryl cyclic-AMP (DBcAMP)-induced changes...

... of these responses was negatively correlated with serum estradiol concentration measured by radioimmunoassay. Urinary norepinephrine output was elevated significantly in treated rats during a 24-hour basal period. During a 2-hour exposure to air at 4 °C, urinary outputs of norepinephrine, epinephrine, and dopamine...

...Ottorino Fanelli; Francesco Tenuta A cardiac stress was performed in the isolated perfused rabbit heart by means of four injections of 0.5 µg epinephrine in the coronary vessels. The endogenous (–)carnitine/acetyl(–)carnitine ratio was also determined. The two exogenous optical isomers of carnitine...

...Robert B. Sanders; Viswanathan Sagur The administration of L -tryptophan prevented the normal rise in blood sugar concentration that usually follows the injection of epinephrine into rats. Of the several possible mechanisms by which tryptophan could inhibit epinephrine-induced hyperglycemia, one...

...R.B. Sanders; W.H. Jacob The injection of epinephrine (1.0 mg/kg) into alloxan-diabetic, fasted rats depressed the serum concentration of previously administered α-aminoisobutyric acid (AIB) and 1-aminocyclopentanecarboxylic acid (ACPC) within 2 h and simultaneously increased the concentration...

...R.B. Sanders; F.S. Abulaban L-Amino acids, when administered intra-peritoneally either individually or as mixtures to fasted rats, blocked the epinephrine-induced hyperglycemic response. The injection of 2.5 mmoles/kg of either arginine, lysine, leucine, isoleucine, threonine, or tryptophan...

...R.B. Sanders; W.H. Jacob The injection of epinephrine (1 mg/kg) into rats caused a significant increase in the distribution ratio (DR) of previously injected 1-aminocyclopentanecarboxylic acid (ACPC) and α-aminoisobutyric acid (AIB) within 2 h. At the same time epinephrine depressed...

...Robert B. Sanders; Viswanathan Sagur Measurements of 3-O-methyl glucose (3-O-MG) transport were undertaken in order to determine whether a specific concentration of tryptophan stimulated glucose transport into peripheral tissues of the rat and might, thereby, prevent epinephrine-induced...

The granules contained 80.9% ATP, 12.3% GTP, and 6.8% UTP, as well as detectable amounts of ADP, AMP, GDP, and UDP. If we...

...A.C. Broughton; D.C. Secord; G.W. Scott The object of this study was to assess the effects of systemic bolus injections of epinephrine and of norepinephrine upon the sphincter at the choledochoduodenal junction in the cat and the dog. The bile duct was transected and the downstream segment...

...Aleksander A. Mathé; Surendra K. Puri; Ladislav Volicer; Richard J. Sohn Cyclic AMP levels and adenylate cyclase and phosphodiesterase activities were measured in control and ovalbumin-sensitized guinea pig lungs. Cyclic AMP levels were raised by epinephrine (0.01–10 μg/ml) in both control...
