FIGURE 7.
eNOS inhibition with LNAME attenuated the response to Up4A to a similar extent in coronary small arteries from Sham-operated swine (A, n = 8) and swine with AoB (B, n = 7). Subsequent inhibition of cyclooxygenase with indomethacin (Indo) had no effect in vessels from Sham (C, n = 7), but enhanced relaxation to Up4A in vessels from swine with AoB (D, n = 6). Control data are the same as in Figure 2 (‘Sham’ and ‘AoB’). ∗P < 0.05 effect of LNAME vs. corresponding control; †P < 0.05 effect of LNAME + indomethacin vs. LNAME alone.
