Figure 1. (A) The effect of GSF (5, 10, 25, 50 100, 250, and 500 μg/mL) on cell viability. (B) The effect of LPS (1, 2, 3, 4, and 5 μg/mL) on cell viability. (C) The effect of GSF on LPS-induced cell viability. (D) Hochest staining of HT-22 cell. *P<0.05, **P<0.01 was considered statistically significant compared with the control group; #P<0.05, ##P<0.01 was considered statistically significant compared with the LPS-induced group.
