Red blood cell life span in the ovine fetus.
Red cell life span within the fetal circulation has not been reported, although erythrocyte life span has been studied in the adult and newborn. The present study quantified red cell life span in 12 chronically catheterized fetal sheep at 97-136 days gestation (term = 150 days) with the use of autologous red cells labeled with [(14)C]cyanate. Cyanate forms a permanent covalent bond with hemoglo...
متن کاملThe life span of the human red blood cell.
Many different methods have been used to estimate the average life time of the human red blood cell. The different attempts have yielded estimates which range from 5 to 200 days. Estimates have been made by inducing polycythemia and noting the time required for the return to the normal red cell count; this yielded values of 18 to 30 days (1). Determinations of the amount of iron or pigment excr...

ALTLAND, PAUL D., AND KIRKLAND C. BRACE. Red cell Zije span in the turfle and toad. Am. J. Physiol. 203(6) : I 188-1 I go. 1962. -Estimates of the mean life span of the red blood cells of box turtles and South American giant toads were made with glycine-2-C . l4 The mean life span of the turtle red cells probably lies between 600 and 800 days and that of the toad between 700 and 1,400 days. The...
متن کاملRed cell life span after splenectomy in hereditary spherocytosis.
Despite the persistence of spherocytosis after splenectomy in hereditary spherocytosis, it has usually been assumed that red cell life span returns completely to normal after this treatment. Diisopropyl fluorophosphate. DF(32)P, a noneluting red cell label, was given intravenously to 11 patients in five unrelated families 2-27 yr after splenectomy for typical hereditary spherocytosis. Hemoglobi...
متن کاملLife span of carbamylated red cells in sickle cell anemia.
By using three isotopes of diisopropyl-phosphofluoridate ([(3)H]-, [(14)C]-, and [(32)P]DFP) simultaneously, the life span of red cells from 20 patients with sickle cell anemia (Hb SS) has been studied after varying degrees of carbamylation in vitro with cyanate (NCO) and carbamyl phosphate (CP). The results are expressed in terms of the red cell mean life span (MLS). The MLS of red cells in th...
