By means of the Takamatsu-Gomori's method, the author examined the phosphatase reaction in gingival of pulmonary tuberculosis patients. The results were as follows:
1) In the gingivas of pulmonary tuberculosis patients, there was no histological findings in regard to tuberculosis proper. However, phosphatase reaction was slightly accelerated than the normal.
2) There was no significant difference in the intensities of the phosphatase reactions in relation with the condition and term of pulmonary tuberculosis.
3) The intensity of phosphatase reactions in various parts was in the following order: in the connective tissue of the deeper layer ; in the compact connective tissue beneath the papilli; in the submucosal tissue migrating in the epithelial tissue; in the tissue with the inflammatory infiltration, and in the vascular vessels. Phosphatase reaction was negative in the epithelial tissue as well as the tissue where the round cell infiltration existed.
4) Based upon the above data, it is considered that the presence of phosphatase reaction in the gingivas has the significance of the developing defence mechanism against inflammation, and that in case of pulmonary tuberculosis, it is much influenced by clinical states, by the seriousness of inflammation, and that phosphatase reaction is accelerated by the secondary inflammation of peridental tissue together with the descending defence mechanism of the whole body.
