Effect of hot water extract of Glechoma hederacea (HWG), rosmarinic acid (RA) on HK-2 and 786-O cells viability after treatment with cisplatin (CDDP). a Chemical structures of RA and CDDP. HK-2 and 786-O cells were exposed to various concentrations of HWG (50–800 μg/mL), RA (25–200 μM) (b) and CDDP (2.5–40 μM) (c) and cell viabilities were measured 48 h later using the MTT assay. The data represent the mean ± SD from three independent experiments. ^∗P < 0.05
