Effect of sonicated extracts of Enterococcus faecalis on the production of matrix metalloproteinase-8 by human polymorphonuclear neutrophils / 대한치과보존학회지

This in vitro study monitored MMP-8 production on PMN by stimulated with the following three groups; Sonicated extracts of E. faecalis (SEF), SEF treated with Ca(OH)2 (12.5mg/ml) for 7 days, and lipopolysaccharides (LPS) of E. coli. The level of MMP-8 in each group was immediately measured by ELISA. The data were analyzed with Kruskal-Wallis test and Mann-Whitney U test. In the SEF group, the level of production of MMP-8 was higher than the negative control group in low concentration (0.05microg/ml) of SEF (p 0.05). All of the levels in E. coli LPS were increased with increasing concentrations (p 0.05).
