Fig. 5. Time course of recovery from anesthesia following dialysis delivery of Ringer's solution (control), the adenosine A1receptor agonist (SPA), or the antagonist plus agonist (DPCPX + SPA). These studies in three animals all used the 8.8-mm SPA concentration. Recovery score is expressed as a function of time with 10 = full recovery and 0 = no recovery. Each data point represents the mean ± SD of at least three individual recovery scores from different experiments. Linear functions for Ringer's solution and SPA are the same as those shown in figure 3. DPCPX + SPA significantly suppressed the slope attenuation induced by 8.8 mm SPA.
