(3) Our results indicate: 1) linear RBC pressure-flow behavior over a driving pressure range of 2 to 10.5 cm H2O with zero velocity intercepts at delta P = 0, thus suggesting the Poiseuille-like nature of the flow; 2) resistance to flow or "apparent viscosities" for normal RBC which are between 3.1 to 3.9 cPoise and are independent of driving pressure and pore geometry; 3) increased flow resistance (i.e., increased transit times) for old versus young RBC and for RBC made less deformable by DNP-induced crenation or by heat treatment at 48 degrees C; 4) increased mean transit time and poorer reproducibility when using EDTA rather than heparin as the anticoagulant agent.

(14) In contrast to the control and the regression rats, many of the hypertrophic vessels of all types in the hypoxic rats showed signs of constriction, ie, crenation of the wall, indentations of medial smooth muscle cell nuclei, and excrescences of smooth muscle cell cytoplasm, often protruding deeply into the endothelium.
(15) We demonstrate that the damage consists of lifting, crenation and detachment of endothelial cells, partially due to contracture and forceful redilation of the vessel wall.

(18) Raising this concentration reversibly decreased the degree of crenation.
(19) These amphiphiles immediately induced strongly crenated erythrocytes which during incubation shifted to less crenated erythrocytes or to stomatocytes.
