Levels of Cyclooxygenase 2, Interleukin-6, and Tumour Necrosis Factor-α in Fibroblast Cell Culture Models after Photobiomodulation at 660 nm

Table 2

The Trypan Blue exclusion assay was performed to assess cellular viability (%) of nonirradiated (0 J/cm²) and irradiated cells (5 J/cm²) at 0, 24, and 48 h postirradiation. An increase in cell viability was noted in the diabetic wounded group at 0 and 24 h postirradiation.

24 h	66 (±7)	77.33 (±6.506)
48 h	91 (±2.646)	86.33 (±1.528)
Normal wounded
0 h	92 (±6.08)	92.67 (±2.08)
