;Cytotoxicity of the LR extracts:

(A) LRH, (B) LRE and (C) LRW against MOLT-4 cells. Cell viability of MOLT-4 cells was determined using the MTS assay. Anti-HIV-1 effect of LRW on HIV-1 infected MOLT-4 cells: (D) Syncytial formation and (E) HIV-1 p24 production inhibitions of LRW (0.5 mg/ml), DMSO (0.1%, v/v), DRV (2 μM) and NVP (2 μM). Data are shown as the mean ± SEM of triplicate values. *P < 0.05 versus the cell control.
