the present study examined the adenosine a1 receptor using n6- [ 3h ] cyclohexyladenosine ( [ 3h ] cha ) , the a2 receptor using 5'-n- [ 3h ] ethylcarboxyamidoadenosine ( [ 3h ] neca ) , adenylate cyclase using [ 3h ] forskolin , and the adenosine uptake site using [ 3h ] nitrobenzylthioinosine ( [ 3h ] nbi ) .
