Figure 2

Percentage relaxation to Ach 10⁻⁵ M and SNP 10⁻⁵ M in control (CON), diabetes (DM), diabetes treated with vitamin C (1g/L) starting on day 2 (DM + AAday2) and on 6 weeks (DM + AA6wk) after STZ injection. Values are mean ± SEM, CON: 𝑛=9, DM: 𝑛=7, DM + AAday2: 𝑛=7, DM + AA6wk: 𝑛=6. ^∗𝑃<0.001 versus CON, ^#𝑃<0.01 versus DM.
