摘要：

Conditions for quantitating the superoxide producing capacity of polymorphonuclear leukocytes are given. It is shown that the production is partly dependent on glucose but independent on Mg2+, Ca2+ and extracellular pH in the range 6.6-8.2. The capacity of normal cells to produce superoxide is estimated to 13.4±0.13 SEM (n=9) femtomoles per min per cell, whereas superoxide production is absent in all cases of chronic granulomatous disease, irrespective of the type. It is suggested that at least 3 enzymes cooperate intimately in the superoxide producing system of the cell. This supports the theory of an electron transport chain of significance for oxygen consumption. © 1979.
