Objectives： This study is experimental comparison of brown rice (BR) and germinated brown rice (GBR) on upper gastrointestinal diseases animal models.
Methods： The ICR mice were divided randomly into four groups of six animals each (Normal mice, gastritis mice, gastritis mice treated with BR, gastritis mice treated with 48h GBR). Gastritis was induced by administration of 0.5 mL 150 mM HCl-60% ethanol. Six.week-old male Sprague-Dawley (SD) rats were randomly divided into 7 groups after 1 week adaptation. (Normal rat, reflux esophagitis (RE) rat, RE rat treated with BR, RE rat treated with 24,30,36,48h GBR). Reflux esophagitis was induced by ligation with a 2-0 silk thread both the pylorus and the transitional junction between the forestomach and the corpus in SD rats.
Results：HCl/ethanol-induced gastric mucosal injury mice were ameliorated mucosal damage upon histological evaluation by treatment of 48h GBR than BR. Optical changes such as hyperemia and multiple erosions were observed in the rats with RE and damage to the normal rats was not apparent. The oral administration of GBR significantly diminished against gross mucosal damage in a germination time-dependent manner. Also, the administration of GBR suppressed the biomarker of oxidative stress, reactive oxygen species (ROS) and produces peroxynitrite (ONOO-) in serum. However, the administration of GBR could not affect to the pH level secreted from stomach when compared with Control group.
Conclusions： These findings suggest that GBR could have improving effects on upper gastrointestinal diseases in a germination time-dependent manner.
