| Abstract: | The dependence of some parameters of L-cells culture viability on different concentrations of heavy metals was studied. Considerable cytotoxic effect of low concentrations of nickel (0.025 mcg/ml) and lead (0.05 mcg/ml) was shown. Copper and chrome at concentrations of 0.25-0.5 mcg/ml promote cells proliferation between third and fifth days of cultivation. Nickel at concentration 0.025 mcg/ml and lead at all investigated concentrations synchronize cells division in culture. Increasing of giant polynucleas cells level in culture was characteristic for investigated metals. The maximum levels of this type cells were caused by the action of nickel, chrome and copper. |
