Time-dependent changes in NO−2 production in control rats and in rats subjected to APC with or without DAHP, before (PreOcc) and during Occ, and after reperfusion (60 and 90 min). Data are expressed as mean ± SE. *P < 0.05 versus PreOcc baseline; †P < 0.05 versus control at the same time point; ‡P < 0.05 versus respective control without DAHP. APC = anesthetic preconditioning; DAHP = 2,4-diamino-6-hydroxypyrimidine; Occ = coronary artery occlusion; PreOcc = before Occ.
