Fig. 4

Concentration-response curves to adenosine with and without the presence of adenosine A2ab receptor blockers in intact (a) and denuded (b) isolated rat aortic rings. In the presence of 100 μM 8-(3-Chlorostyryl) caffeine (■) or 10 μM PSB 0788 (■). Controls (intact and denuded rings) (♦). Relaxation is expressed as percent of maximal relaxation to 100 μM papaverine. Points represent mean ± S.E.M of aortic rings from a total of eight animals. *P < 0.05 statistical difference in responses between the presence and the absence of inhibitors on intact rings
