Figure 2. Diameter changes in porcine coronary arteries to 60 min of hypoxia and 60 min of reoxygenation calculated with respect to normoxic steady state diameter (A) and diameter changes to continued oxygenation (B).

*P < 0.05 versus no blockade. #P < 0.05 versus corresponding condition during initial oxygen time period; n = 5–8 in all experiments. Error bars indicate s.e.m.
