Continuous Electrical Current and Zinc Sulphate Administered by Transdermal Iontophoresis Improves Skin Healing in Diabetic Rats Induced by Alloxan: Morphological and Ultrastructural Analysis
Figure 6
Photomicrographs of surgical scars from the skin of normal rat ((a), (b), and (c)) and diabetic ((d), (e), and (f)), sacrificed on postoperative day 21, showing organized deposition of dense, wavy provisions collagen horizontally on the epithelial surface, surgical wounds in rats of NG/NT (a), NG/CEC (b), NG/Zn + TDI (c), and DG/Zn + TDI (f). Note that this ultrastructural pattern of collagen deposition was not observed in scars of untreated (d) or treated with CEC alone (e) (EM - 3000x) diabetic rats.
