FIGURE 4.
P1 receptor blockade with 8PT attenuated relaxation to Up4A less in coronary small arteries from Sham-operated swine (A, n = 6) as compared to coronary small arteries from swine with AoB (B, n = 6). A2A receptor blockade with SCH58261 attenuated Up4A-induced relaxation in coronary small arteries from Sham (n = 5), but not AoB (n = 5). Control data are the same as in Figure 2 (‘Sham’ and ‘AoB’). ∗P < 0.05 effect of 8PT vs. corresponding control. †P < 0.05 effect of 8PT vs. corresponding SCH58261.
