Corneal wound healing in normal and diabetic rats treated with AV.
Notes: (A) Slit lamp photographs of fluorescein staining of corneal epithelial defects in NAV, NC, DAV, and DC groups at 0, 24, 48, and 72 hours postwounding. Photographs of fluorescein staining showing better wound healing in the NAV group than in NC group at 24 and 48 hours postwounding, while DAV showing smaller corneal epithelial defect than DC at 24, 48, and 72 hours postwounding. (B) The percentage of wound area in NAV, NC, DAV, and DC groups at 0, 24, 48, and 72 hours postwounding. Data are expressed as mean ± SD (n=7 rats, each group). *Significant difference in the wound area between DC group and NC group (P<0.05). **Significant difference in the wound area between NAV group and NC group (P<0.05). ***Significant difference in the wound area between DAV group and DC group (P<0.05).
Abbreviations: NC, normal control; NAV, normal aloe vera; DC, diabetic control; DAV, diabetic aloe vera; h, hours; SD, standard deviation; AV, aloe vera.
