From: Protective effect of resveratrol and quercetin on in vitro-induced diabetic mouse corpus cavernosum
(Vaso)relaxant effect of resveratrol or quercetin in presence of high glucose and methylglyoxal. a Aorta, b mesenteric artery and c corpora cavernosa. Tissues were incubated for 2 h with 30 mM glucose (HG) and 120 µM methylglyoxal (MGO) before constructing concentration–response (1–100 µM) curves to resveratrol (Res, 15 min) or quercetin (Quer, 15 min). Data are expressed as % decrease of Phe-induced tone; Mann–Whitney U test; #p < 0.01 and *p < 0.05 (vehicle control vs. Res) (n = 5–6); ##p < 0.01 and **p < 0.05 (vehicle control vs. Quer) (n = 5–6)
