2. Fig. 1
Concentration–response curves to NA in (A) endothelium-intact and (B) endothelium-denuded aortic rings from control and vitamin C-treated rats. All concentrations represent final bath concentrations. Each point on the graphs represents mean±SEM of 5–7 rings from different animals. *P<0.05 compared with control rats (Student's t-test).

3. Fig. 2
Concentration–response curves to KCl in (A) endothelium-intact and (B) endothelium-denuded aortic rings from control and vitamin C-treated rats. All concentrations represent final bath concentrations. Each point on the graphs represents mean±SEM of 6–9 rings from different animals. *P<0.05 compared with control rats (Student's t-test).

4. Fig. 3
Relaxation response of aortic rings to ACh from control and vitamin C-treated rats. Relaxation responses are expressed as percentage of decrease in submaximal contraction elicited by NA (10−7 mol/l). Each point on the graph represents mean±SEM of 7 rings from different animals. *P<0.05 compared with control rats (Student's t-test).

5. Fig. 4
Relaxation response of aortic rings to sodium SNP from control and vitamin C-treated rats. Relaxation responses are expressed as percentage of decrease in submaximal contraction elicited by NA (10−7 mol/l). Each point on the graph represents mean±SEM of 7 rings from different animals.
