Effects of eNOS and iNOS expression by agmatine treatment following transient global cerebral ischemia in rat cerebral cortex. Representative expressional levels of eNOS (A) and iNOS (C) at 24 h after agmatine treatment (100 mg/kg, i.p), and densitometric data (B, D). Data represent means±SD for n=5/NC, n=3/EC and Agm group per each time point. ^*P<0.05, vs. normal control; ^†P<0.05, vs. experimental control at same onset of reperfusion. NC, normal control; EC6, at 6 h after reperfusion without agmatine; Agm6, at 6 h after reperfusion with agmatine; EC24, at 24 h after reperfusion without agmatine; Agm24, at 24 h after reperfusion with agmatine.
