[Evaluation of the damaging and transforming effect of sodium nitrite on cultured lung cells].
The toxic and transformation actions of sodium nitrite (NN) were studied on the primary lung cell cultures of 3-day old noninbred rats. The monolayer density, mitotic index, DNA-synthetizing activity of cells, frequency of pathological mitoses changes in the character of growth, appearance of the multilayer growth foci serve as a criteria for evaluation. It is established that sodium nitrite has a transforming effect on lung cells and that the concentration of 1.035 mg/ml of nutrient medium is a transforming dose at 48 h exposition. Summation of the effect by prolongation of cell exposition with the NN prethreshold doses is possible.
