An erythrocyte transport function (ETF) is proposed, as an index of the efficiency of the circulation of red cells. Under defined conditions, this ETF is shown to be proportional to the ratio of haematocrit to whole-blood viscosity (phi/eta), a ratio already used by Chien. The variations of phi/eta with phi, at selected driving pressures in a capillary viscometer, are presented, both for normal and for pathological blood samples. Maximal values of phi/eta appear generally to occur at…

It is suggested that abnormally raised plasma and serum viscosities, by contributing to disturbances in normal blood flow and metabolism, may play an essential role in the development of both micro-circulatory disorders and hypertension in some Nigerian diabetics.

Cardiac rehabilitation improves blood rheology in patients with CHD by reducing mu45 and PV and elevating tau(rbc) and these improvements may contribute to the increased functional capacity and reduced morbidity and mortality that is associated with participation in cardiac rehabilitation and exercise programs.

The hyperviscosity syndrome commonly includes mucous membrane bleeding, retinopathy and loss of vision, and neurological disorders associated with elevated serum viscosity, and is frequently seen in patients with macroglobulinemia, with or without demonstrable lymphoma, but only rarely with multiple myeloma.
