RED CELL MASS AND LIFE SPAN IN THE RAT DURING PERIODS OF PHYSIOLOGICAL HYPER TRANSFUSION

摘要

A double isotope method for simultaneous measurement of red cell and plasma volumes has been developed for use in the rat. The DFP 32 red cell life span method has also been adapted to use in the rat, involving test and comparison of three different injection and sampling techniques.nMale rats reacclimatizing to sea level brought their hematocrits to normal as much by rapid weight gain with a nearly proportional increase in plasma volume as by destruction of red cells.
