A METHOD FOR LABELING LEUKOCYTES WITH RADIOACTIVE DIISOPROPYL FLUOROPHOSPHATE (DFP32) *

For a better understanding of leukocyte pathophysiology i t would be helpful if the leukocyte compartments and turnover rates could be measured in normal subjects, as well as in a variety of clinical situations. Numerous attempts to obtain this information have been made, but the studies have given contradictory results. First, different animal species have been used, and it is possible that leukocyte life span is not the same in all species. Also, a distinction must be made These results might be expected to differ for several reasons.
