Figure 3. Effects of the NADPH inhibitor apocynin on DHE fluorescence (indicating superoxide anion levels).

Figure 3

Several cells and nuclei from diabetic male rats are shown either in the absence (A) or in the presence (B) of apocynin (300 μm, 6 h). Scale bar, 10 μm. C, mean (±s.e.m.) DHE fluorescence intensity in the absence (open bar, normalized as 100%) and presence of the drug (hatched bar), for one set of cells. *P < 0.05. A similar significant reduction of DHE intensity by apocynin was obtained in five other experiments.
