[Effect of streptovaricin on the multiplication of L line cells].

An inhibitor of the reverse trascriptase-streptovaricin in a dose of 4 mkg/ml would induce an increase of the DNA amount in L cell nuclei, while its dosage of 8 mkg/ml decrease the amount of DNA, resulting in the differentiation of some population cells. Streptovaricin inhibited the L cell multiplication, rendering no significant effect on that of normal fibroblasts of C3H mice culture.
