Effects of 20 (S)-ginsenoside Rg3 on NOS2 expressions. (A) Immunohistochemical analyses of NOS2 in different groups in the alcohol GU model, pylorus-ligated GU model, and acetic acid GU model (×200). Positive NOS2 staining cells of different groups in the (B) alcohol GU model, (C) pylorus-ligated GU model, (D) and acetic acid GU model. Data are presented as the mean ± SD (n = 10; compared with the blank control group, #p < 0.05, ##p < 0.01, ###p < 0.001; compared with the model control group, *p < 0.05, **p < 0.01, ***p < 0.001).
GU, gastric ulcer; H-Rg3, high-dose Rg3 group; L-Rg3, low-dose Rg3 group; M-Rg3, moderate-dose Rg3 group; NOS2, nitric oxide synthase; SD, standard deviation.
