RBC Survival in Hamsters Using Intraperitoneal Na 2 Cr 51 O 4 ∗

Abstract

Conclusion

1. Intraperitoneal administration of sodium chromate⁵¹ results in the effective chromation in vivo of red cells in the golden hamster. 2. With use of this labelling technic the erythrocyte survival of the normal golden hamster has been shown to be between 60 to 70 days. 3. The advantages of tagging erythrocytes in vivo include relative ease of administration of chromium and elimination of the necessity of obtaining a large initial blood sample.
