Figure 3From: Dietary potassium supplementation improves vascular structure and ameliorates the damage caused by cerebral ischemia in normotensive ratsDietary 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).Back to article page
