[The effect of the interferon inducer ridostin on photrin-induced mutagenesis in bone marrow cells in mice].

The number of aberrant metaphases was used to assess the influence of a highly active interferon inducer--ridostin, a two-spiral RNA, on spontaneous mutagenesis and that induced by an antitumor drug photrin. A new property of ridostin, viz. the antimutagenic effect, was established. The effect may be important for protection of cells from potent mutagens such as cytotoxic drugs used for cancer treatment.
