Fig. 4From: Role of neuronal nitric oxide synthase (nNOS) at medulla in tachycardia induced by repeated administration of ethanol in conscious ratsBar graphs show Western blot analysis of the levels of nNOS (a), iNOS (b), eNOS (c) and changes in NOx (d) content in rostroventral medulla at 30 min after oral gavage of saline (10 mL/kg) or ethanol (3.2 g/kg) at day 8 treatment. Ethanol or saline was administered once every day for 8 consecutive days (n = 4 each). The ratio of different NOS to β-actin in saline group is taken as control of 100%. *P < 0.05 versus saline group analyzed using unpaired t-testBack to article page
