Bone marrow as multidimensional orbit oscillator after autologous bone marrow transplantation.

The local renin-angiotensin system (RAS) in bone marrow is probably involved in the control of hematopoiesis. Earlier observations suggest the relationship between the frequency of sodium and potassium concentration changes in urine and bone marrow recovery after chemotherapy. The purpose of this study was to prove the relationship between sodium and potassium excretion changes in urine and granulocyte counts in peripheral blood after autologous bone marrow and peripheral blood stem cell transplantation.
