Nigella sativa L. Seed Extract Modulates the Neurotransmitter Amino Acids Release in Cultured Neurons In Vitro

Figure 1

Effect of Nigella sativa methanolic extract on neuronal viability measured by MTT assay. The cells were stimulated for 15 and 60 minutes with different concentrations of this extract (2.5, 25 and 250 μ/mL, final concentration). The results are presented as SEM of three independent experiments and statistical analysis resulted in no significant differences when compared with the control group.
