Expression of tight junction proteins claudin-4 (b) and claudin-5 (c) on esophagus in RE-induced rats (a). Rats were pre-treated with 100 and 200 mg/kg body weight DGK excluding normal and RE control for 90 min before surgery, which was performed under inhalation anesthesia. Then, 5 h later, the esophageal tissue was cut, and then, the was abdomen open and removed from each rat. Data are means ± standard deviation (SD). significance: ^# p < 0.05 and * p < 0.05 compared with normal control and RE control groups, respectively.
