Fig. 2.

Effects of tubular flow rate on inner tubular diameters in the absence and presence of dextran-80. (A) Photograph taken from an experiment showing the measurement of inner diameters. (B) Changes of tubular inner diameters in response to perfusion rate in the absence (▴) and presence (▪) of dextran-80. Inner diameters were increased significantly when the perfusion rate was enhanced from 5 nl/min to 10, 15, 20, and 25 nl/min in both groups. There was no significant difference between control and dextran groups.
