Saliva Crystallization Features in Young People with Different Levels of Physical Activity

Abstract

The aim of the study was to estimate the features of dehydration structuring of saliva in untrained people. Methods and Results: The study included 35 untrained students (Group 1) and 38 people who regularly exercise (Group 2), who do not have any chronic diseases. The mean age of participants was 17-18 years. The crystallogenic activity and initiatory potential were evaluated for each sample of biological fluid. The crystallization of mixed saliva was studied using the method of classical crystalloscopy, and the initiating properties were studied by the method of comparative tezigraphy. A 0.9% sodium chloride solution was used as the base substance in the tezigraphic test. The conducted crystalloscopic studies have demonstrated significant differences in the crystallogenic and initiating properties of mixed saliva in people who regularly engage in physical training, compared with untrained individuals. They manifest themselves in a significant qualitative and quantitative transformation of the crystalloscopic picture of the biological fluid, including single-crystalline and dendritic components, as well as in the representation of amorphous bodies in micro-preparations of the biological medium. In the tezigraphic test, it was found that the initiatory potential of mixed saliva also undergoes significant shifts. These shifts are realized in the activation of the initiating ability of biological fluid and optimization of textural characteristics of tezigrams (reduction of cellular density and increase in uniformity) in combination with a decrease in the degree of destruction of structural picture elements and a moderate expansion of the marginal zone of micro-preparations.
