[The characteristics of the phospholipid composition of the pulp in the milk teeth].

Qualitative and quantitative phospholipid composition of porcine deciduous teeth pulp was studied by microthin-layer chromatography. Basing on the differences in the levels of individual phospholipids in the pulp of deciduous and permanent teeth, the authors come to a conclusion on the inadequate structural organization and functional activity of the pulp of deciduous teeth.

[Morphologic changes in the dental and periodontal tissues of rats exposed to autonomotropic preparations].

Autonomotropic [correction of Vegetotropic] drugs were injected to 40 rats for 10 days in order to detect changes in incisor growth rate and the morphologic changes in dental and periodontal tissues related with this changed rate. Adrenalin-enhanced eruption is associated with enhanced dentinogenesis and osteogenesis with increased salt deposition. Atropine, a cholinolytic, sharply inhibits incisor growth, this being parallelled with congestion in the pulpal and periodontal vessels and emergence of alveolar process bone tissue resolution.
