Figure 1. Effect of CSE on the cell viability and NO production in LPS-stimulated BV-2 cells. Cells were incubated with indicated concentrations of CSE for 1 h before incubation with LPS (1 µg/mL) for 24 h. Cell viability was evaluated using the MTT assay. Results are shown as percentage of control samples (A). The nitrite levels were measured as NO release (µM) in the culture media using the Griess reaction (B). Data are presented as the mean ± S.E.M. (n =6). ^###P<0.001, vs. control group and ^*p < 0.05, ^**p < 0.01 and ^***p < 0.001 vs. LPS treated group. NS: Not significant; CSE: Coriandrum sativum extract.
