Figure 2. Age and pulse pressure modulate the contribution of reactive oxygen species to endothelium-dependent dilation.

Figure 2.

In (A) young and (B) old posterior cerebral arteries (PCAs) the maximal response to acetylcholine in the absence and presence of PEG-catalase following static pressure, low pulse pressure (PP), and high PP exposure. n=6–20/group, *p<0.05, **p<0.01, ***p<0.001 with vs. without PEG-catalase assessed by independent samples t-tests within same pressure condition. Values are mean ± SD.
