Figure 2: Garlic extract (GE)-induced oxidative stress in human leukemia (HL-60) cells. Cells were incubated for 12 hr with increasing concentrations of GE (2, 4, 6, 8, and 10 mg/mL). Malondialdehyde (MDA) concentrations were determined as described in Materials and Methods. *Significantly different from the control by ANOVA Dunnett’s test; P < 0.05. Data are representative of 3 independent experiments.
