Biophysics of blood in chronic renal failure

ABSTRACT

Rennin, aldosterone and kidney functions besides conductivity and viscosity of blood of chronic renal failure patients either non dialyzed or under regular hemodialysis were studied. The obtained data revealed an increment of rennin and aldosterone coupled with disorder in kidney functions. Regular hemodialysis has a pronounced effect through volume decrease of the extracellular fluid. This decrement comes from the volume depletion which is in its turn related to the plasma rennin activity. The reflection of these results appeared as an amelioration in blood pressure, viscosity and conductivity due to shift of water and toxic materials out of the blood
