Neuroprotective Activity of Methanolic Extract of Lysimachia christinae against Glutamate Toxicity in HT22 Cell and Its Protective Mechanisms

Figure 1

Cell viability after treatment of L. christinae extract and glutamate in HT22 cells. Cells were pretreated with 1.0, 5.0, 10.0, 20.0, and 50.0 μg/ml of L. christinae and trolox (30 μM), respectively. Then, 2.5 mM glutamate was treated for 30 μl after 1 h. Each bar expresses the mean ± S.D of three replicated processes. , , and compared to glutamate-injured cells (ANOVA).
