Short-time effects due to low-power, low-energy (HeNe and GaAs) laser irradiation were studied in two cellular systems: an embryonal-human-cell line (EUE) and yeast cells (Saccharomyces cerevisiae). In EUE cells «short-term effect» as chemical-energy transduction in cytoskeletal aggregation was evaluated. In yeast cells the glycolitic CO2 production was taken as an index of redox decarboxylative processes, while adenylnucleotides were tested to evaluated the ATP and adenylate energy charge (AEC) modification. In both cellular systems effects enhanced by laser irradiation were found. A theoretical approach (based on cellular automata) is hinted accounting for the ponderomotive forces induced by the electromagentic field.
