Alterations in rheological properties and erythrocyte membrane proteins in cats with diabetes mellitus (original) (raw)

Clinical hemorheology and microcirculation, 2005

Abstract

Many studies have shown that diabetes mellitus is associated with increased whole and blood viscosity and decreased erythrocyte deformability. It has been suggested that these abnormalities in blood rheology may play a causative role in the pathogenesis of diabetic vascular complications. However, less is known about the content and quality of membrane proteins which may contribute to abnormalities in membrane dynamic and decreased erythrocyte deformability. In the present study we analysed various rheological parameters (blood and plasma viscosity, erythrocyte deformability, haemotological parameters), in cats with non-insulin dependent diabetes mellitus (NIDDM). We also investigated alterations in erythrocyte membrane protein content by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). We found that erythrocyte rigidity and plasma and whole blood viscosities were significantly higher in cats with NIDDM compared to controls. SDS-PAGE revealed that the band 5 cor...
