Negundoside, an iridiod glycoside from leaves of Vitex negundo, protects human liver cells against calcium-mediated toxicity induced by carbon tetrachloride

Figure 4 Membrane stabilizing effect of NG and silymarin on human RBCs. RBC suspensions were pre-incubated with or without (control) test materials and triton (1 g/L) in phosphate buffered saline as described in Materials and Methods section. Data are mean ± SD (n = 3) and representative of one of three similar experiments and statistically significant P values: ^bP < 0.01; ^aP < 0.05; ^dP < 0.001; NS = Non-significant. Triton treated vs control cells; triton + NG/silymarin vs triton treated cells.
