Abstract

Purpose: The antibiotic effect of rice-fluid on Helicobacter pylori infection was investigated using a Mongolian gerbil model.

Methods: Gerbils were divided into four groups: H. pylori -infected, rice-fluid-treated animals (group A); H. pylori -infected, untreated animals (group B); uninfected, rice-fluid-treated animals (group C); and uninfected, untreated animals (group D). Group A and B animals were killed 14 weeks after H. pylori infection and group C and D animals were killed at the same age. The stomachs were examined for histology, 5'-bromo-2'-deoxyuridine (BrdU) labeling, and the bacterial burden. Serum anti-H. pylori antibody titers were also tested.

Results: The positive incidence of H. pylori -culture was 25 and 84 % in groups A and B, respectively (p<0.01). Both the degree of inflammation and the BrdU labeling index in group A were significantly lower than those in group B.

Conclusions: Rice-fluid showed an antibiotic effect on H. pylori and an anti-inflammatory effect on the H. pylori -associated gastritis.

Keywords: Japanese Rice-fluid, Helicobacter pylori, Mongolian gerbil, eradication, prevention
