1. Scintigraphic imaging identifies pathophysiological processes; in other words it assesses regional perfusion, permeability, leukocytic accumulation and bone turnover.

2. A large human phage antibody library was subjected for panning with leukocytes from healthy donors and leukemia patients to select for specific antibodies against leukocytic surface proteins.

4. The short circulating half-life of PMNs relative to other leukocytic cell types, and their critical role as a front line of defense against infectious agents Ascribes particular importance to this regulatory process.
