Abstract
Granulocytes are known to exhibit positive chemotaxis towards erythroc ytes destroyed by laser irradiation (necrotaxis). A computerized metho d for visualizing intracellular calcium concentration in granulocytes during necrotaxis has been developed. Successive bursts of fluorescenc e were observed: 1-degrees) about 10 s after the creation of the necro tactic source; 2-degrees) when the granulocyte touched the target.
