Spinal anesthesia alleviates dextran sodium sulfate-induced colitis by modulating the gut microbiota

Figure 7 Spinal anesthesia decreases the noradrenaline level induced by dextran sodium sulfate. At the end of the experiment, according to Figure 1A, the serum of mice in each group was collected. A: Noradrenaline level measured by high performance liquid chromatography (HPLC); B: Quantitation of the HPLC result. Data are presented as the mean ± SEM of three independent experiments. P values were calculated using one-way ANOVA between different groups. ^aP < 0.05. 5-ASA: 5-aminosalicylic acid; DSS: Dextran sodium sulfate.
