Figure 1. EGb761 increased cell viability against Aβ_{1 –42} oligomer toxicity.

Panel A, bEnd.3 cells were incubated with various concentrations of EGb761 for 24 h and then cell viability was analyzed according to MTT assay by detecting the absorbance at 490 nm. Panel B, cells were incubated with or without various concentrations of EGb761 for 2 h, followed by incubation with 10 µM Aβ_1–42 oligomer for 24 h. Subsequently, cell viability was determined by MTT assay. Results are shown as the Mean±S.E.M. (*p<0.01, Aβ versus Control; #p<0.01, EGb761+Aβ versus Aβ; **p<0.05, versus Aβ).
