FIG. 2 — Effects of a Tribulus terrestris extract on the relaxation response of the rat corpus cavernosum (CC). The relaxation response of the CC was suppressed only by the nitric oxide synthesis inhibitor L-arginine methyl ester (L-NAME) and endothelium-denuded [E (-)] CC. Pretreatment with indomethacin (Indome), glibenclamide (GB), 4-aminopyridine (4-AP), or methylene blue (MB) for 30 minutes did not suppress the relaxation of the CC by the T. terrestris extract (p<0.05, n=8/group). PE, phenylephrine. ^*,†p<0.05.
