This provides selective accumulation of proposed protected oligonucleotides (fRNA) in cancer cells and also provides the absence toxicity in the fRNA.Materials and methods For the immunotherapy we used immunotropic 70 kDa lectin B. subtilis B-7025. In vivo experiments were carried out in C57BL line mice in Lewis lung carcinoma. The cytotoxic activity, lymphocytes, macrophages was determined in vitro using the MTT assay.Results and discussion Animal survival rate in groups receiving either the fRNA or Vaccine was 70 and 40%, respectively. Combined use fRNA and Vaccine has the advantage compared with the use these drugs in monotherapy, as the anticancer efficacy of the scheme is much higher, which is manifested in the primary tumor node and metastasis inhibition.
