✦ Synopsis

Whole blood luminol-enhanced chemiluminescence (CL) was studied using N-formylmethionyl-leucyl-phenylalanine (FMLP) or opsonized zymosan particles as stimuli. The peak and the integral responses of CL were recorded. In the FMLP-induced CL the initial activation (I-minute values) was also studied, because it coincides with the extracellular production of oxy radicals. Correction factors based on neutrophil count and on haemoglobin concentration were found t o decrease dispersion and shape the distributions of the CL responses close t o normal in a study of 50 healthy adults. One-minute values were significantly lower in women than in men but there were no significant differences for peak or integral values between sexes. Depressed reaction is in accordance with the previous findings that phagocytic oxy radical production is depressed in female plasma. Thus, our results suggest that I-minute value is a variable more sensitive than peak or integral value of the CL response.
