a , compared with SIG, differences were significant ( ), b , compared with HDG, differences in corresponding phase points were significant ( ), c , compared with HDG, differences in corresponding phase points were significant ( , , ); d , compared with HDG, differences in corresponding phase points were significant ( value in phases, resp., were 7.654, 12.64, 17.69, 21.24, 14.81, 13.21, and 15.84); e , compared with HDG, differences in corresponding phase points were significant ( value in phases, resp., were 5.279, 11.63, 7.698, 13.55, 12.85, 4.281, 4.845, and 24.88) f , compared with HDG, differences in corresponding phase points were significant ( value in phases, resp., were 6.774, 7.386, 5.047, 24.02, 3.792, 5.146, 9.548, and 16.49).
One-way ANOVA, the proportion of apoptotic fibroblasts showed no difference among the ARG1 (7.2 J/cm2), ARG2 (14.4 J/cm2), and ARG3 (28.8 J/cm2), ; -test, no difference observed between ARG4 (57.6 J/cm2) and ARG3 (115.2 J/cm2), .
