title: Anti-helicobacter pylori activities of shoya powder and essential oils of thymus vulgaris and eucalyptus globulus.
abstract: BACKGROUND
  Helicobacter pylori, an infective agent of more than 50% of the world population is prominent to be the main causative factor in the etiologies of chronic, active or type B gastritis, peptic and duodenal ulcer, gastric carcinoma, and mucosa-associated lymphoid tumors. A high prevalence of this bacterium in dental plaque is always reported. Pharmacological treatment of H. pylori infections includes administration of 3-fold therapeutic regimens which are typically used to suppress H. pylori activity. However, antibiotic resistance frequently develops as a consequence of such treatment. Thus, searching for alternative therapies for H. pylori infections is of special interest.
  
  
  METHODS
  In this study, anti H. pylori activities of a traditional antimicrobial drug so-called Shoya and also essential oils of Thymus vulgaris and Eucalyptus globulus were investigated using antimicrobial analysis and serological screening methods.
  
  
  RESULTS
  The agar dilution method results revealed the Shoya with the highest inhibitory effect against H. pylori. Also serological screening on tested mice showed a significant effect of this drug in lowering the sera amount of anti H. pylori specific IgA and IgG titers. Both of the essential oils showed different degrees of antibacterial effect against H. pylori.
  
  
  CONCLUSIONS
  The obtained results showed the antibacterial effect of Shoya powder and Essential oils from Thymus vulgaris and Eucalyptus globulus and purposes new therapeutical alternatives to control the H. pylori infection. Additional studies and clinical trials are necessary to approve the use of these data in health care and pharmacopeia systems.
