in contrast to previous reports on the requirement of the copresence of adenosine for alpha receptor stimulated accumulation of cyclic amp in neuronal tissue , the pe-stimulation in spinal cord slices was unchanged by adenosine receptor blockade ( theophylline ) , hydrolysis of endogenous adenosine ( adenosine deaminase ) , inhibition of adenosine deaminase ( ehna ) or blockade of adenosine uptake ( dipyridamole ) .
