Continuous Electrical Current and Zinc Sulphate Administered by Transdermal Iontophoresis Improves Skin Healing in Diabetic Rats Induced by Alloxan: Morphological and Ultrastructural Analysis

Figure 5

Photomicrographs of surgical scars from the skin of normal rat ((a), (b), and (c)) and diabetic ((d), (e), and (f)), sacrificed on postoperative day 7. Note that the process of reepithelialization of incisional surgery wounds is still incomplete (arrows) in rats of NG/NT and DG/NT, the largest increase ((a) and (d)). Note the disorganized collagen deposition thin, with multiple fenestrations (f) in NG and DG rats with incisions treated with CEC alone ((b) and (e)) compared with the deposition of dense collagen with few fenestrations observed in mouse NG and NG with incisions treated with Zn + TDI ((c) and (f)) (ME - 3000x).
