The present study was conducted to investigate the histological changes and wound healing effect of aqueous extract of Elaeagnus angustifolia. After creating full-thickness skin wounds on the back of 45 male Sprague-Dawley rats they were randomly divided into three groups. Treated group received the extract, positive control group were treated with mupirocin ointment 2% and control group did not receive any treatment. Wound healing rates were calculated on days 3, 5, 8, 10, 12 and 15 post-wounding and the wound tissues were harvested at 5, 10, and 15 days for histological analysis and hydroxyproline content measurement. The results indicated a significant increase in the percentage of wound contraction and hydroxyproline content in the treated group comparing to the control and positive control groups. A significant increase in the assigned histological scores was observed at 10 and 15 days in the treated and positive control groups compared to the control group. The results demonstrate that aqueous extract of Elaeagnus angustifolia accelerates cutaneous wound healing, and its effect may be due to the increased re-epithelialization and collagen deposition in wound and so it can be considered as a therapeutic agent for wound healing.
本研究旨在探讨沙枣水提取物的组织学变化及伤口愈合效果。在45只雄性Sprague-Dawley大鼠背部制造全层皮肤伤口后,将它们随机分为三组。治疗组接受提取物治疗,阳性对照组用2%莫匹罗星软膏治疗,对照组不接受任何治疗。在伤口形成后的第3、5、8、10、12和15天计算伤口愈合率,并在第5、10和15天采集伤口组织进行组织学分析和羟脯氨酸含量测定。结果表明,与对照组和阳性对照组相比,治疗组的伤口收缩百分比和羟脯氨酸含量显著增加。与对照组相比,治疗组和阳性对照组在第10天和15天的指定组织学评分显著增加。结果表明,沙枣水提取物可加速皮肤伤口愈合,其作用可能是由于伤口处再上皮化和胶原蛋白沉积增加,因此可被视为一种伤口愈合治疗剂。
