CFMs reduce viabilities of the human MB cells.

<p>Cells were treated with vehicle (Control) or indicated doses of CFMs for 12 h (A) or 24 h (B). In panel C and D, the cells were treated with respective CFM for noted dose and time. Determination of viable/live cells was carried out by MTT assay. The data in the histograms represent means of three independent experiments; bars, S.E. ∗, p = <0.05 relative to Control (A, B) or 0.00 (C, D).
