The effect of 5 hydroxytryptamine (5-HT) on gastric acid secretion by the rat isolated stomach has been studied. 5-HT (10 microM) significantly inhibited secretory responses to pentagastrin, histamine and isoprenaline but not those due to bethanechol, dibutyryl cyclic AMP or

A quasi-morphine withdrawal syndrome (QMWS) is a pattern of behavior closely resembling the true withdrawal syndrome in the opiate-dependent animal, which can be elicited acutely by a nonopiate drug in an opiate-naive animal. The main criteria proposed for the QMWS

The aim of the present investigation was to examine whether or not presynaptic facilitatory beta-adrenoceptors are detectable on the postganglionic nerves in the rabbit isolated ear artery. Strips of rabbit central ear artery were incubated with 3H-noradrenaline (10(-7) mol/l; 30

We examined the effects of prolonged exposure of cardiac cells in primary culture to the partial beta-adrenoceptor agonist prenalterol and inhibitors of phosphodiesterase on their subsequent ability to increase intracellular cyclic AMP during a 5-min exposure to 50 microM isoprenaline

Peripheral blood lymphocyte cyclic AMP responses to isoprenaline, prostaglandin E2 and histamine were examined in patients with atopic eczema, in the presence and absence of a potent phosphodiesterase inhibitor (PDEI). Basal cyclic AMP levels were not significantly different in atopic
