Figure 5
Baseline reduced mean values (A) and baseline reduce and normalized (B) dose–response curves of red blood cell concentration as measured by polarized spectroscopy (TiVi), before and during iontophoresis of acetylcholine in five concentrations and control solution (sterilized water). n = 15. Acetylcholine was delivered during 10 min at three repetitions separated by 30 min wash-out between each iontophoretic pulse (1–3). Error bars show standard error of the mean (SEM).
