[Changes in the histochemical structures of the gingiva in the topical use of plant based drug].

If the active permeability of the oral mucosa ensures the possibility of the direct application of various substances, its influence on the intensity of metabolic processes must be detectable in the histochemical way. The present animal experiments were intended for verifying thaction of a preparation (Herbadont) on the basis of vegetable active principles on changes in the contents of ribonucleic acid, glycogen and SH and COOH groups in the gingiva. It was shown that the removal of clinical inflammatory symptoms by this preparation is associated with a decrease in the contents of COOH and SH groups, ribonucleoproteids and glucogen which are increased in case of disease. Concomitantly, the intensity of the reaction on NH2 groups and the ascorbic acid content increase.
