The lactate dehydrogenase (LDH) assay used to assess LDH released by human NP cells treated with PBM. Human NP cells exposed to MCM were irradiated using PBM at 64 J/cm2, which is the maximum dose used in this study. The data show that none of the wavelengths, used in this study, were cytotoxic to human NP cells. Values are mean ± SE of three or four independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001 as compared with control, and line indicates comparison with each group.
