Fig. 3. Relationships between flow and diameter and between shear stress and diameter in endothelium-intact and -denuded arterioles pressurized to 120 mmHg during perfusion and superfusion with physiologic saline containing 5 mm D-glucose or 20 mm D-glucose. P < 0.05 for difference between endothelium-denuded arterioles exposed to 5 mm D-glucose and those exposed to 20 mm D-glucose.
