[Screening diagnosis of membrane-destructive process in children with maxillodental abnormalities and gastrointestinal diseases].

Native mixed saliva of 86 children with congenital and acquired dentognathic system deformations and gastrointestinal tract diseases was investigated by specially devised method using optical reflecting microscope Neophot-2. In cytological preparations of mixed saliva all the cell elements were with signs of significant edema and cytolysis. In detritus different structures of lipid aggregations prevailed.

[Functional digital subtraction sialography in the diagnosis of salivary gland diseases].

Functional digital subtraction sialography with a water soluble radiopaque agent (verografin) made it possible to investigate the structure and functional changes in the salivary glands of 26 patients with a minimum injury of the glands. The method permitted a decrease in a dose of the agent 4 times as compared to routine sialography; the consumption of x-ray film was decreased 5-fold. Digital processing of images helped avoid superimposing of the cranial bone components, improving the quality of images of the salivary glands.
