Figure 5: Immunoperoxidase Bcl2 stained sections of group1. Seborrheic keratosis before peeling reveal increased number of Bcl2 positive cells in basal layers of the lesion (5a), while, after GA peeling show the same number of positive cells in the basal and suprabasal cell layers (5b). Actinic keratosis before peeling show increased number of Bcl2 positive epidermal cells (5c), while, after GA peeling show few positive basal epidermal cells (5d). Solar lentigines before peeling show increased number of Bcl2 positive cells in the basal and suprabasal cell layers (5e), while GA treated skin show few positive epidermal cells (5f) (bar scale, 50 µm).
