Abstract

A qualirative E.P.R. (Electron Paramagnetic Resonance) study has been performed to determine the action of Low Level Lasers on living cells, Singlet oxygen (1O2) was found to be generated by Friend Erythroleukaemic Cells (FELC) after irradiating them with a HeNe laser. The production of 1O2 in the cell during irradiation was proved by an E.P.R. technique. No singlet oxygen is photoproduced by irradiating either cytochrome C or hemin.
Singlet oxygen, in small amounts, is very significant in biochemical processes and hence can be important in biostimulation. It is proposed that singlet oxygen is photoproduced by the natural porphyrins in the cell.
