| I/R group | 0.427±0.234 | 0.499±0.255 | 0.554±0.268 | 0.659±0.290 |

The differences among rats in the I/R group, Ast group, and control group are significant (F=10.482, p<0.01). *At 8 h, 12 h, and 24 h, the difference in the AQP4 level was significant between the I/R group and Ast group (t8h=2.86, t12h=3.611, t24h=4.72, p<0.05). However, the AQP4 level was not significantly different between the I/R and Ast group at 48 h (t=2.513, p>0.05), h - hours, I/R - ischemia-reperfusion
