... This study examined the role of plasma lipids in the regulation of erythrocyte membrane viscosity, oxy-Hb content as well as Na+/H+ exchange and Ca2+-ATPase, whose activities are altered in patients with CVD. Both oxy-Hb content and erythrocyte membrane fluidity were decreased in essential hypertension and coronary artery disease patients and negatively correlated with plasma cholesterol but not triglyceride content. ... 2007 Biophysics dep., ...
