| Abstract: | A study of 24 patients with chronic renal failure and varying degrees of uremia and clinical symptoms was carried out in order to assess the mechanisms of anemia developing in patients on systematic hemodialysis for chronic renal failure. Blood clinical and biochemical parameters were evaluated. Sternal bone marrow puncture was performed to assess erythron status. Proliferative activity of bone marrow erythroid cells was assessed by autoradiography. Ineffective erythropoiesis was studied using MacManus' PAS test. The results of the study suggest that proliferative activity of bone-marrow erythroid cells is reduced while ineffective erythropoiesis is increased in patients with terminal chronic renal failure, treated by systematic hemodialysis, and largely explain the mechanism of anemia in these patients. |
