Figure 1: Cytotoxic effect of garlic extract to human leukemia (HL-60) cells. HL- 60 cells were cultured with increasing concentrations of garlic extract (2, 4, 6, 8, and 10 mg/mL) for 12 hr as indicated in the Materials and Methods. Cell viability was determined based on the MTT assay. Each point represents a mean ± SD of 3 experiments with 6 replicates per dose. *Significantly different (p <0.05) from the control, according to the Dunnett’s test.
