Fig. 1. A) The untreated lesion on day 10 post-injury. The connective tissue of the dermis is highly infi ltrated with infl ammatory cells (arrows); the newly formed collagen fi bers are unorganized and show a haphazardly distributed pattern. The glycosaminoglycan formation in the dermis is scanty (H&E; ×220). B) The treated lesion on day 10 post-injury. Numerous blood vessels of different sizes are seen in this section (arrows). The collagen fi bers show a primitive organized pattern and the tissue alignment is greater as compared to untreated lesions (H&E; ×180).
