Medicinal plants are crucial to healing numerous illnesses. Elaeis guineensis Jacq (family Arecaceae) is a medicinal plant traditionally used for the treatment of wounds.
However, there are no scientific reports documented on the wound healing activities of this plant against Staphylococcus aureus infections in the Sprague Dawley male rat model. Thus, the present study was conducted to evaluate the wound healing potential of E. guineensis extract leaves.
The crude extract was prepared in 10% (w/w) ointment and evaluated for wound healing activity using excision and infected wound models in Sprague Dawley rats. The wound healing activity was evaluated from wound closure rate, CFU reduction, histological analysis of granulation tissue and matrix metalloprotease expression.
The results show that the E. guineensis extract has potent wound healing ability, as manifest from improved wound closure and tissue regeneration supported by histopathological parameters. Assessment of granulation tissue every fourth day showed a significant reduction in the microbial count. The expression of matrix metalloproteinases was well correlated with the other results, hence confirming E. guineensis wound healing activity's effectiveness.
E. guineensis enhanced infected wound healing in rats, thus supporting its traditional use.
药用植物对于治疗许多疾病至关重要。油棕(棕榈科)是一种传统的药用植物,用于治疗伤口。
然而,目前尚无科学报道记录这种植物对金黄色葡萄球菌感染的斯普拉格-道利雄性大鼠模型的伤口愈合活性。因此,本研究旨在评估油棕叶提取物的伤口愈合潜力。
将粗提取物制备成 10%(w/w)的软膏,并使用切除和感染性伤口模型在斯普拉格-道利大鼠中评估其伤口愈合活性。通过伤口闭合率、CFU 减少、肉芽组织和基质金属蛋白酶表达的组织学分析来评估伤口愈合活性。
结果表明,油棕提取物具有很强的伤口愈合能力,表现在改善的伤口闭合和组织再生,这得到了组织病理学参数的支持。每隔四天评估肉芽组织显示微生物计数显著减少。基质金属蛋白酶的表达与其他结果密切相关,因此证实了油棕的伤口愈合活性的有效性。
油棕增强了大鼠的感染性伤口愈合,从而支持了其传统用途。
