Summary

<i>Moringa oleifera</i> is known to possess wound healing activity. The present study evaluated the healing properties of methanolic extract of <i>M. oleifera</i> leaves in excision wounds infected with methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) or <i>P. aeruginosa</i> in diabetic rats. An in vitro study was also carried out to determine the gene expression of VEGF and TGF-β1. Preliminary phytochemical and GC-MS analyses were carried out to determine different chemical constituents present in the extract. <i>M. oleifera</i> was applied locally as an ointment at two different concentrations. Wound contraction, period of epithelization, antioxidant enzyme activities and histological changes were determined. For the gene expression study, HaCaT cell lines were used. The formulation of <i>M. oleifera</i> extract improved wound contraction and decreased the period of epithelization, which was associated with an increase in antioxidant enzyme activities, epithelization, capillary density and collagen formation in <i>MRSA</i>-infected diabetic rats. However, this effect was reduced in diabetic animals infected with <i>P. aeruginosa</i>. An increase in the expression of VEGF and TGF-β1 was observed in HaCaT cell lines. <i>M. oleifera</i> extract promotes the healing of infected wounds in <i>MRSA</i>-infected diabetic rats but is less effective in the healing of wounds infected with <i>P. aeruginosa</i> in diabetic rats.
