Antioxidant Activity of Lawsonia inermis Extracts Inhibits Chromium(VI)-Induced Cellular and DNA Toxicity
Figure 3
Dosage-dependent inhibition of Cr(VI)-induced cytotoxicity in MDA-MB-435S (human breast carcinoma) cells by aqueous and methanolic extracts of L. inermis as estimated by XTT assay. Sample cells were treated with 10 M Cr(VI) for 24 h with the following extract-dosages: (A): 0 g; (B): 125 g; (C): 250 g; (D): 500 g; (E): 1000 g. Control cells (without Cr and/or extract treatment) were used as reference for evaluating percentage cytotoxicity. Values given are as mean SD for samples ().
