Figure 5. Distribution of wall shear stress along the vessel wall from the base (0 mm) to the end (110 mm) simulated for the mean of the maximum value of pulsatile cycle represented in Figure 2 at a flow of 2.5 mL/min. N = 4-6 animals in each group. A and B, Effect of PEG 4000 on the wall shear stress (Pa = Pascal) along the wall of the tail arterial bed with intact endothelium (E+) from Wistar rats and spontaneously hypertensive rats (SHR), respectively; C and D, effect of endothelial damage (E-) on PEG-induced changes in wall shear stress in the tail arterial beds from Wistar rats and SHR, respectively.
