The expression of PDGF-A and PDGFR were reduced in R group during inflammatory responsive and granulation formation periods (14 - 28 days after radiation, the IA value of PDGF-A varied from 14.0 +/- 1.2 to 20.3 +/- 1.2 compared with that in T group in which the IA value of PDGF-A at the same period (3 - 9 days after injury) varied from 20.0 +/- 1.6 to 28.3 +/- 1.0, and reduced gradually during scar formation period (55 days after radiation).
