FIG. 2.

Bactericidal activity of the supernatant of stimulated granulocytes at pH 5.0 and 37°C. For control experiments, inactivation by the addition of thiosulfate was carried out prior to addition of bacteria. The results are the means ± the standard errors of the means (SEM) of 3 to 4 separate experiments. All differences between control (dotted lines) and test samples (solid lines) were significant (P < 0.01).
