Saliva as new analytical object for D-dimer level determination.

The amount of D-dimer in the mixed saliva of healthy individuals and patients with comorbidities has been investigated. It has been established that the level of D-dimer in saliva increases with age regardless of pathology. The highest values were found in patients with erosive gastritis.

[Study of the quantity of interleukin-6 by SDS-PAAG electrophoresis and immuno-enzyme analysis in mixed saliva after rinsing the oral cavity with oligonucleotide specific.]

The selective properties of a solution of oligonucleotide specific to IL-6 on the concentration of IL-6 in mixed saliva of patients with oral inflammatory processes were studied using SDS-PAGE by electrophoresis and enzyme immunoassay. The application of these methods showed that in the mixed saliva of patients after rinsing with a solution of an oligonucleotide specific for IL-6, the amount of IL-6 decreases. The ELISA Kit and 20% SDS-PAGE showed the highest sensitivity to determine the concentration of IL-6 in saliva, which should be considered in clinical laboratory practice.
