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 significance of a characteristic symptomatology (hypothermia, hypoactivity, forepaw shaking, grooming, head twitches) as a potential in vivo correlate of enhanced availability of brain adenosine cyclic 3',5'-monophosphate (cAMP) was examined in rats following systemic administration of various doses of dibutyryladenosine

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

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

The possible involvement of cyclic AMP in the stimulation-evoked 3H-overflow from rabbit isolated ear artery preloaded with 3H-noradrenaline was studied. Cyclic AMP (10(-5)-3 x 10(-4)M), 8-bromo-cyclic AMP (3 x 10(-4)M) and adenosine (10(-5)-3 x 10(-4)M) enhanced stimulation-evoked 3H-overflow. Dibutyryl-cyclic AMP
