title: DNA synthesis in monkey kidney cellular culture, hematoporphyrin sensitized and He--Ne laser irradiated.
abstract: He--Ne laser irradiation for 1-45 J/cm2 has four actions upon monkey kidney cell cultures: a) a stimulation of nuclear DNA synthesis after 20 J/cm2; b) a diminution of replication after higher dose (45 J/cm2); c) inhibition of nuclear DNA synthesis and d) a marked cytotoxic effect. At lower radiation fluences (1-5 J/cm2) the influence on the biosynthesis of DNA is not significant.
