Denatured radioiodinated human serum albumin (DHA) clearance studies at a dose of 1 mg/kg body wt., were carried out in 16 thalassemic children, prior to and 7-10 days following blood transfusion, to investigate changes of the effective RES blood flow which might accompany the posttransfusion spleen size diminution. A statistically significant increase (P… (More)
In order to investigate the effect of blood transfusion on the RE cell function in thalassemia major, 14 children with homozygous beta thalassemia were studied prior to and 7 to 10 d following blood transfusion, when, according to previous studies, spleen reaches its minimum size. The denatured human albumin (DHA) low and large dose clearance techniques… (More)
