Potential rat model of anxiety-like gastric hypersensitivity induced by sequential stress

Figure 3 Abdominal withdrawal reflex and electromyographic tests showed the sequential-stress-treated rats exhibited gastric hypersensitivity to gastric distention. A: AWR to GD of the sequential-stress-treated rats was significantly higher at the distention pressure 40, 60, 80 and 100 mmHg; B: EMG responses of the sequential-stress-treated rats were greater at the distention pressure 40, 60, 80 and 100 mmHg; C: The representative EMG response from both an adult sequential-stress-treated rat and control rat to GD. Data were expressed as the mean ± SEM of the AWR score and the percentage of EMG derived AUC increased (n = 8 in each group). ^aP < 0.05, ^bP < 0.01 vs control group.
