STUDIES ON SO CALLED PYORRHEA ALVEOLARIS. (XIV) : Pyorrhea Alveolaris and Alkaline Phosphatase in Neutrophilic Leucocytes : Alkaline Phosphatase in Neutrophilic Leucocytes of Completely Healthy Controls

We researched on alkaline phosphatase in neutrophilic leucocytes in 209 healthy controls aged from 6 to 74. TAKEUCHI's phosphatase staining method was adopted. The results obtained were as follows. : 1) The mean percentage of positive alkaline phosphatase in neutrophilie leucocytes of 209 cases showed (52.67±0.65)%. 2) There was no remarkable difference between female and male. 3) The percentages of alkaline phosphatase in neutrophilic leucocytes of cases 10∿14 years old were low slightly, but there were not remarkable differences among ages from 15 to 29. 4) There is distinct difference between percentages of positive alkaline phosphatase in neutrophilic leucocytes of alveolar pyorrhea patients (very high) and that of healthy controls (low).
