Короткий огляд (реферат): The aim of the present study was to investigate the co - effect produced by water - soluble form of quercetin and epigall o- catechin - 3 - gallate (EGCG) on biochemical markers of periodontal organic matrix depolimerization under systemic admin i- stration and local application of S. typhi lipopolisaccharide (LPS). The studies were conducted on 3 0 white rats of the Wistar line weighi ng 180 - 220 g, divided into 5 groups: the 1 st included intact animals, the 2 nd was made up of animals after the combined systemic and local LPS administration, the 3 rd and 4 th groups included animals, which were being given injections with water - soluble for m of quercetin (10 mg / kg) and EGCG (21.1 mg / kg ) respectively 3 times a week, starting on the 30 th day of the systemic LPS administration, and the 5 th group involved rats, which were injected with co - administered water - soluble form of quercetin and EGCG . It has been found out that the co - effect pr o duced by quercetin and EGCG under systemic and local LPS a d ministration is accompanied with reduced concentration of N - acetylneuraminic acid (NANA) by 31.8 and 32.8% respectively in the soft periodontal tissues compared with values for the animals r e- ceived separate quercetin and EGCG during the experiment. However, no differences have been detected between the groups exposed to combined or separate action of the above mentioned agents in the experiment when a ss essing free hydroxyproline (FHP) and glycosaminoglycans (GAGs) content in the soft tissues of periodontium. At the same time combined use of quercetin and EGCG under experimental conditions led to the decrease in the FHP content in the alve o- lar bone by 24. 5 and 20.2% respectively compared with values for the animals received separate quercetin and EGCG. NANA concentration was reduced by 35.0 and 41.3% respectively. Thus, the co - administration of water - soluble form of quercetin and epigallocatechin - 3 - gallate under systemic and local introducing of S. typhi lipopolysaccharide has been proven to be more effective means for preventing and correcting periodontal connective tissue disruption than this o c- curs at separate administration of each of the pol y phenols.
