Effects of anesthesia and surgery on depression-like symptoms in OFT, TST, FST, and SPT. The results of OFT, TST, FST, and SPT in control and A+S mice. (A) The schedule of the experiment. A+S was performed on day 0 after acclimation. OFT and TST were measured on day 1, 8, 15, and 22 after A+S, respectively. FST was performed on day 2, 9, 16, and 23 after A+S, respectively. SPT was performed on day 6, 13, 20, and 27 after A+S, respectively. (B) OFT [time: F

(3,
54) = 0.4846, P = 0.6944] was measured in control and A+S groups. Data are shown as mean ± SEM (n = 10). *P < 0.05, **P < 0.01, ***P < 0.001. A+S, anesthesia and surgery; FST, forced swimming test; N.S., not significant; OFT, open field test, SPT, sucrose preference test; TST, tail suspension test.
