The survival time of rabbit's erythrocytes. I. Elimination of auto- and allogenic erythrocytes radioactively labeled with chromium 51Cr from circulation.

: The speed of eliminating allogenic erythrocytes labeled with 51Cr from circulation was examined. Donor's erythrocytes with AFHR phenotype were injected to the recipient with FR phenotype. A fast elimination of allogenic erythrocytes was observed, T 1/2 = 7.6 days. The survival time of autogenic erythrocytes was T 1/2 = 18.2 days. In sera of those rabbits to whom allogenic erythrocytes had been injected, no anti-erythrocyte antibodies against the donor's hemocytes appeared.
