The Neuroprotective Effects of Ratanasampil on Oxidative Stress-Mediated Neuronal Damage in Human Neuronal SH-SY5Y Cells

Figure 2

The effects of RNSP in different solvents and times on H2O2-induced toxicity in SH-SY5Y cells. Pretreatment with water extracts (a) and methanol extracts (b) of RNSP for 5 days. Each column and bar represent the mean ± SEM ( each). Asterisks indicate a statistically significant difference from the value in the H2O2-exposed cells without RNSP (). The effect of pretreatment with methanol extracts of RNSP for 2 h (c) and 2 h two times in a 2 h interval (2-2 h) (d) on H2O2-exposed SH-SY5Y cells. Each column and bar represent the mean ± SEM ( each). Asterisks indicate a statistically significant difference from the value in the H2O2-incubated cells without RNSP ().
