Figure 3

Dietary potassium supplementation increases the inner (A) and outer diameter (B) of the middle cerebral artery. Arteries were mounted in a small vessel arteriograph and the inner and outer diameters of the vessels were measured over a range of intralumenal pressures (20–180 mmHg) under zero flow and calcium free conditions. Results were compared by a two way repeated measures ANOVA (p < 0.05) n = 5 for the HK group and 6 for the LK group).
