Figure 3 Detection of H₂O₂ Production With DCF Fluorescent Method

Hydrogen peroxide (H₂O₂) production was unaltered after N^G-monomethyl-L-arginine (L-NMMA) but was markedly suppressed by catalase. Number of arterioles/animals used was 5/5 for each group. *p < 0.05, **p < 0.01. DCF = 2',7'-dichlorodihydrofluorescein diacetate.
