[Effects of constant magnetic field on the growth and metastasizing of Lewis carcinoma in mice].

In mice with the metastasizing Lewis carcinoma the constant magnetic field (CMF) was studied for its effect on growth and metastatic process depending on the immobilization of animals. The results obtained show a decrease in the rate of the primary tumour growth and in the intensity of the metastatic process under the influence of CMF by incomplete immobilization. Complete immobilization eliminates the antimetastatic effects of the CMF.

[NAD participation in protecting DNA from damaging factors].

It was found that autolytic degradation of DNA during the isolation of nuclei under conditions of an in situ stimulated NAD biosynthesis is decreased to 2.5% in comparison with 5.2% in control.
