| Abstract: | The concentration of plasma Fn was determined in non-splenectomized and splenectomized patients with homozygous beta-thalassemia, before and 7-10 days after blood transfusion. The mean Fn concentration of non-splenectomized patients before transfusion did not differ from that of matched normal controls but appeared significantly decreased following blood transfusion. On the other hand, in splenectomized thalassemics, Fn levels were increased but were unrelated to transfusion. It is concluded that Fn plays some homeostatic function when RES activity of thalassemic patients is altered either as a result of splenectomy or blood transfusion. |
