Surgical trauma and anesthesia and fecal microbiota transplantation significantly enhanced hippocampal IL-6 expression on postoperative or post-transplantation day 3 compared with the control group. Pretreatment with SCFAs partially reversed the higher expression of IL-6. The effects of SCFAs pretreatment for reversed IL-6 expression was maintained until day 7 compared with that of the surgery group. (A) The level of hippocampal IL-6 on postoperative or post-transplantation day 3. (B) The level of hippocampal IL-6 on postoperative or post-transplantation day 7. The results are represented as mean ± SEM. **p < 0.001 vs. the day-matched control group, #p < 0.05 vs. the day-matched surgery group, ##p < 0.001 vs. the day-matched surgery group. P3 and P7: postoperative or post-transplantation days 3 and 7, respectively.
