Modulation of Extracellular ATP Content of Mast Cells and DRG Neurons by Irradiation: Studies on Underlying Mechanism of Low-Level-Laser Therapy

Figure 6

Extracellular ATP content of rat DRG neurons in response to 657 nm, 18 mW/cm2, and 21 J/cm2 laser irradiation. Relative changes of extracellular ATP level of rat DRG neurons induced by laser irradiation averaged for respective irradiation times of all samples. The data represent averages ± SEM from independent experiments. compared to the preirradiation value; compared to the preirradiation in the presence of ARL 67156 value.
