Figure 6. Effect of 810-nm laser on nitric oxide (NO) production in cortical neurons with excitotoxicity.
(A) DAF-FM (green) fluorescence for NO in cortical neurons as control and with 3 excitotoxins, with and without LLLT (3 J/cm2 810 nm laser). Scale bar = 20 µm. (B) Quantification by Image J of mean fluorescence values. N= 6 fields per group. Error bars are SEM and * = p <0.05; ** = p <0.01 vs sham (dark).
