[A bacterial model for research on the effect of laser radiation on the intensity of cell division].

Abstract

A bacterial model is proposed for the prognosing, at the cellular level, of the effectiveness and safety of low-intensity laser therapy. In experiments with E. coli WP2, a study was made of the effect of continuous optical radiation as well as of pulse radiation at medical installations "Uzor" (890 nm, 1.2 x 10(-1) W/m2, 3400 Hz) and "Omega" (950 nm, 1.2 x 10(3) W/m2, 2-5000 Hz). A technique has been developed to determine a minimum dose of low-intensity radiation that provides normalization of the cell division rate at a pathological site excluding the risk of the uncontrolled proliferation of the surrounding tissues.
