The cytotoxic and antiproliferative effects of silver nitrate on H-Ras 5RP7 cells (a) and NIH/3T3 cells (b) treated with different concentration (1.9–3.9–7.8–15.6–31.2–62.5–125–250 μM/ml) over a 24 h time period. Cell survival of each well was monitored by MTT assay. Significantly different from control, *p < 0.05. Data were recorded as mean ± SD
