Final ΔLp relative to baseline Lp plotted as a function of the average wall shear stress, τ. A: vessels perfused with BSA solutions. None of the vessels in the forward-flow (open symbols) group had a ΔLp higher than 4. The reverse-flow (closed symbols) group was more variable with five vessels having ΔLp below 4 and six vessels with ΔLp above 4. There was no clear relationship with wall shear stress. B: vessels perfused with CSHA solutions. None of the vessels in the forward-flow group (open symbols) had ΔLp higher than 4. The reverse-flow group (closed symbols) was variable with three vessels having ΔLp below 4 and four vessels with ΔLp above 4. There was no clear relationship with wall shear stress. CS, chondroitin sulfate; HA, hyaluronic acid. See results for description of CSHA solution.
