Half Life of RBCs Obtained From CBA-+/+ and-Pk-1slc/Pk-1slc Mice of Various Ages After Transfusion Into 90-Day-Old CBA-+/+

Age of RBC Donors (d) Half Life (d, mean ± SE)*
+/+Pk-1slc/Pk-1slc
2.4 ± 0.1  1.8 ± 0.1

42  6.0 ± 0.2 1.4 ± 0.1,1-153

Age of RBC Donors (d) Half Life (d, mean ± SE)*
+/+Pk-1slc/Pk-1slc

*Calculated from the same data shown in Fig 2. Half lives of RBCs obtained from 1-day-old and 7-day-old CBA-Pk-1slc/Pk-1slc and -+/+ mice and those of RBCs from 42-day-old and 90-day-old CBA-Pk-1slc/Pk-1slc mice were calculated using the first component of the two-component curves.

P < .01 when compared with values of CBA-+/+ mice of the same age by t-test.

P < .01 when compared with values of 1-day-old CBA-+/+ mice.

F1-153

P < .01 when compared with values of 1-day-old CBA-Pk-1slc/Pk-1slc mice.
