Objective : Reflux esophagitis (RE) is a disease that caused gastric acid reflux and inflammation due to unstable gastroesophageal sphincter, as increasing worldwide respectively. This study was conducted to evaluate the effect of Evodiae Fructus (EF) extract on chronic reflux esophagitis in rats.
Methods : The EF was measured antioxidant activity, such as total polyphenol and total flavonoid contents, 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2’-azinobis-3-ethyl-enzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity. Rats were divided into 3 groups; Nor (normal group), Con (chronic acid reflux esophagitis rats treatment with water), EF (chronic acid reflux esophagitis rat treatment with EF 200 mg/kg body weight group). A surgically-induced chronic acid reflux esophagitis (CARE) model was established in SD rats, and treated with water or EF 200 mg/kg body weight for 14 consecutive days.
Results : Administration of EF to rats of induction of chronic acid reflux esophagitis was found to reduce esophagus tissues injury. Reactive oxygen species (ROS) and produces peroxynitrite (ONOO-) levels of esophagus tissues were significantly decreased in EF compared to Con group. As results of esophagus protein analyses, EF effectively reduce inflammatory-related factors (NF-Bp65, p-IB, iNOS, TNF-, IL-6), and increase anti-oxidant enzyme (Nrf2, HO-1, SOD, catalase, GPx-1/2).
Conclusions : These results suggest that EF administration comfirmed that decreased esophagus tissues injury, oxidantive stress, anti-inflammation effect, and increased anti-oxidant effect. Therefore, EF was the potential to be used as a natural therapeutic drug.
