Fig. (1) Effect of LCLE (50, 100, 150 µg/ml) on cell growth (A-C) and cytotoxicity studies (D-F) in U937, K562 and HL-60 cells. Cell count studies after 24, 48 and 72 h. of LCLE (50, 100, 150 µg/ml) treatment in U937 cells (A), K562 cells (B) and HL-60 cells (C), Cytotoxicity studies by performing MTT assays after LCLE (50, 100, 150 µg/ml) treatment for 24, 48 and 72 h. in U937 cells (D), K562 cells (E) and HL- 60 cells (F). Ara-C (200µg/ml) was used as standard reference anti-cancer drug.
