  1. Samples were collected from each group 7, 14 and 21 days after injury. Values are the mean and standard deviation of each group and were compared by ANOVA with Tukey’s post-test
  2. C untreated control, L treated with 670-nm InGaP laser, P treated with the Porophyllum ruderale extract, PL treated with the P. ruderale extract and 670-nm InGaP laser
  3. Asterisk (*) indicates significant differences (p < 0.05)
