[Hemorheologic changes in cancer patients]

The authors examined 23 patients, suffering from malignant tumors. They made some micro- and macrorheological investigations (whole blood viscosity, yield shear stress, plasma viscosity, initial filtration rate, red cell transit time, clogging particles). The whole blood viscosity was nearly normal in all patients. The yield shear stress was elevated in 9 patients, the plasma viscosity was abnormal in 13 patient's. They showed out the significant effect of own patients plasma on erythrocyte deformability. They found 7 patients having normal erythrocyte deformability in phosphate buffer and abnormal (significant elevated red cell transit time) in own plasma.
