3′,4′-Dihydroxyflavonol Reduces Superoxide and Improves Nitric Oxide Function in Diabetic Rat Mesenteric Arteries
Figure 4
Contribution of EDHF to endothelium-dependent relaxation in mesenteric arteries.
EDHF-type relaxation in mesenteric arteries isolated from A, normal, B, diabetic, C, normal+DiOHF, D, diabetic+DiOHF rats. In each group of experiments, arteries were precontracted with phenylephrine to similar level: A, 62±3, B, 63±4, C, 63±4, D, 61±2%KPSS, n = 5–12 experiments. Results are shown as mean±SEM. See Table 2 for values.
