Fig 1: (A) Vagus nerve stimulation improves clinical measurements of inflammation following TNBS injection. (A) The quality of stool produced from unstimulated (TNBS; n = 8) and stimulated (TNBS+VNS; n = 7) rats were scored following the TNBS injection. (B) Blood in stool produced from unstimulated (TNBS; n = 5) and stimulated (TNBS + VNS; n = 4) rats was scored following TNBS injection. (C) CRP content in blood plasma was measured in unstimulated (TNBS; n = 6) and stimulated (TNBS+VNS; n = 6) on day 0 (pre-TNBS control) and days 1, 2, and 4 following TNBS injection. All data show mean ± SEM. Significant differences from control (day 0, pre-TNBS) are indicated by “*”, while significant differences between unstimulated (TNBS) and stimulated (TNBS+VNS) groups are indicated by “O”.
