Abstract

Enhanced generation of H₂O₂, modulations in metabolic activity, and the ldquoby-standerrdquo effect from malignant human brain cancer cells due to red He-Ne laser exposures have been quantified and found to be light exposure dose dependent. The findings herein support evidence for an important role for light induced H₂O₂ to mediate biomodulations.
