OBJECTIVE: This study was undertaken to test the hypothesis that beta-adrenoceptor stimulation of fetal lung fluid absorption in near-term guinea pig fetuses involves bumetanide-sensitive ion transport. STUDY DESIGN: Fetuses were obtained from…

Endogenous epinephrine has been found to increase alveolar liquid clearance (ALC) in several pulmonary edema models. In this study, we infused epinephrine intravenously for 1 h in anesthetized rats to produce plasma epinephrine concentrations…

Factors associated with a single bout of dynamic exercise (increased circulating catecholamines, increased body temperature, and decreased pH) are known to attenuate the vascular response to alpha-adrenergic receptor activation. Therefore, we…

Rats were trained to discriminate phenylephrine in a two-lever, food-motivated operant task by increasing the i.p. administered training dose from 0.8 to 2 mg/kg. Stable discrimination to 2 mg/kg phenylephrine was established and testing of 0.5-2.5…

Several serotonergic and adrenergic agents were tested for an ability to interact with mu, delta, and kappa opioid binding sites. Spiroxatrine interacted nearly equipotently with all three opioid subtypes, yielding K(i) values near 110 nM. A number…
