[Mechanism of lysosome-mediated eradication activity of macrophages on specific anti-Helicobacter pylori of patchouli alcohol].

The aim of this paper is to investigate the effect of patchouli alcohol in enhancing Helicobater pylori's action in eradicating macrophages and its mechanism. H. pylori was co-cultured with macrophages at a ratio of MOI=100 in different concentrations of patchouli alcohol. The effect of patchouli alcohol in eradicating macrophages was detected by agar dilution method. The effect of patchouli alcohol on NO and myeloperoxidase (MPO) levels in macrophages were measured by H. pylori by biochemical methods. Patchouli alcohol effect on H. pylori-induced pro-inflammatory gene expression and protein secretion in macrophages were detected by RT-qPCR and ELISA method. The eradication of H. pylori has significantly enhanced, and the destabilization of lysosomes has been reversed. Meanwhile, patchouli alcohol has an effect in inhibiting pro-inflammation and oxidation. The mechanism of patchouli alcohol in eradicating H. pylori and resisting oxidative stress may be associated to the blocking of bacteria escape lysosome combination procedures.
