[Comparative studies of the glycogen content in the gingiva in patients with periodontal disease and in experimental dogs].

Comparative examinations were carried out on the Glycogen content in the gingiva of patients suffering from parodontal disease as well as in dogs with experimental model of parodontal disease. The latter was obtained by stimulation of the mandibular nerve by means of a silk ligature. Thirty-five biopsies were taken from the patients, suffering from parodontal disease and eight - from 4 experimental dogs. The preparations were treated with periodic acid (PAS reaction).
