Aim:
To study wound healing activity of the human placental extract (HPE) in rats.
Methods:
Full thickness wounds were inflicted on depilated dorsum of Charles foster rats with 8 mm Acu-punch biopsy. The HPE was applied both at topical and im routes (2.5 mL/kg). Effects were compared on the basis of physical criteria, biochemical criteria, and histopathological study with respect to untreated control, vehicle control (1.5 % benzyl alcohol), and framycetin topical treated groups.
Results:
Significant lowering of wound size (P<0.05), wound index (P<0.05), and number of days required for complete healing (P<0.01); significant gain in tensile strength (P<0.01); appreciable increase of tissue DNA, total protein, and collagenesis were observed in HPE treated group.
Conclusion:
Human placental extract systematically helps collagenesis leading to potent healing of wounds.
