[Effect of impulse laser radiation on the synthesis of nucleic acids and proteins in cancer cells].

It was shown that laser irradiation with small doses stimulates the nucleic and protein syntheses in Ehrlich ascites tumour cells. Large doses, on the contrary, were shown to inhibit the nucleic acid and protein metabolism. The synthesis of DNA in tumour cells was more sensitive to laser radiation than that of RNA and proteins. The data obtained show some new mechanisms of the biological action of laser radiation.
