Abstract:

AIM: To investigate the inhibitory effects of emodin, baicalin, etc. on the hefA gene of multidrug resistance (MDR) in Helicobacter pylori (H. pylori).

METHODS: The double dilution method was used to screen MDR H. pylori strains and determine the minimum inhibitory concentrations (MICs) of emodin, baicalin, schizandrin, berberine, clarithromycin, metronidazole, tetracycline, amoxicillin and levofloxacin against H. pylori strains. After the screened MDR stains were treated with emodin, baicalin, schizandrin or berberine at a 1/2 MIC concentration for 48 h, changes in MICs of amoxicillin, tetracycline, levofloxacin, metronidazole and clarithromycin were determined. MDR strains with reduced MICs of amoxicillin were selected to detect the hefA mRNA expression by real-time quantitative PCR.

RESULTS: A total of four MDR H. pylori strains were screened. Treatment with emodin, baicalin, schizandrin and berberine significantly decreased the MICs of amoxicillin and tetracycline against some strains, decreased by 1 to 2 times, but did not significantly change the MICs of clarithromycin, levofloxacin, and metronidazole against MDR strains. In the majority of strains with reduced MICs of amoxicillin, hefA mRNA expression was decreased; one-way ANOVA (SPSS 12.0) used for comparative analysis, P<0.05.

CONCLUSION: Emodin, baicalin, schizandrin and berberine significantly decreased the MICs of amoxicillin and tetracycline against some H. pylori strains, possibly by mechanisms associated with decreasing hefA mRNA expression.
