The effects of single and chronic doses of rolipram on the sensitivity of alpha 2-adrenoceptors have been compared with the phosphodiesterase inhibitors, isobutylmethylxanthine (IBMX) and ICI 63,197, and the antidepressant, desipramine. While pretreatment with a single dose of rolipram, ICI

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

1. Cyclic AMP and cyclic GMP levels were determined in bovine splenic nerve segments in the absence and presence of (+/-)-isoprenaline, (-)-phenylephrine, clonidine and ICI 63 197 (a phosphodiesterase inhibitor). The chosen concentrations of adrenoceptor agonists were those which are

1. Cyclic AMP levels have been determined in the soleus muscles of anaesthetized cats in the absence of drugs, and during depression of incomplete tetanic contractions produced by (-)-isoprenaline, ICI 63,197 (a phosphodiesterase inhibitor) or levodopa. 2. Cyclic AMP levels

Using experimentally derived data for the activities and kinetic constants of hepatocyte cyclic AMP phosphodiesterase isoenzymes together with the derived changes in adenylate cyclase activity, due to stimulation and subsequent desensitization by glucagon, a computer model was established to simulate
