Effects of endotoxin on myocardial hemodynamics, performance, and metabolism during beta adrenergic blockade.

Effects of three beta adrenergic receptor agonists on growth performance, blood biochemical parameters, fatty acids composition and carnitine palmitoyltransferase I gene expression of rainbow trout Oncorhynchus mykiss

Different beta 1 and 2 adrenergic receptor agonists may be various biological and physiological effects on fish species. An experiment was designed to study the effects of feeding ractopamine, terbutaline and metaproterenol; as beta1, beta2 and less selective beta 2 adrenergic receptor agonists, respectively; on body weight gain, feed conversion ratio, concentration of biochemical parameters in...

Cholinergic modulation of the coronary vasoconstriction induced by cocaine in conscious dogs.

BACKGROUND The effects of cocaine on the coronary circulation were examined in conscious dogs chronically instrumented to measure arterial and left ventricular pressures, coronary blood flow, and arterial and coronary sinus oxygen content. METHODS AND RESULTS With heart rate held constant, the peak effects of cocaine (1 mg/kg i.v.) occurred within 2 minutes, when mean arterial pressure increa...

Effects of Beta-Adrenergic Agents on Hypokalemia

288 Communications to the Editor food should interfere with nitrate effects.’ Recent hemodynamic studies in coronary patients indicate increased cardiac and stroke index without changes in mean arterial or pulmonary wedge pressures, which is consistent with the effect of food on STI in our Previous studies of normal conscious dogs were also in agreement, indicating an enhanced inotropic state d...
