Steud () belongs to the family Asteraceae. It has several uses in folk medicine in the Arabian Peninsula. The current study aimed at evaluating the wound healing properties of the extract in rats. Primarily, successfully accelerated cell migration and it also showed no signs of dermal toxicity. Topical application of extract (5% or 20%) expedited healing of excised skin in rats. Histological examinations indicated that shortened epithelization period, stimulated fibroblast activity, and increased collagen deposition in wound tissues. The plant extract exerted antioxidant activity as evidenced by inhibition of GSH depletion and MDA accumulation and enhanced mRNA expression of Sod1 in wound tissues collected at the end of the experiment. Further, inhibited the rise of TNF- and IL-1 in the skin wound region. The anti-inflammatory was confirmed by the observed down regulation of Ptgs2, Nos2, IL-6, and NF-B mRNA expression. In addition, the extract enhanced the expression of TGF-1 and HIF-1 in wounded skin tissues as indicated immunohistochemically. Conclusively, expedites excision wound healing in rats. Collagen-enhancing, anti-inflammatory, and antioxidant properties mediate the observed wound healing activity. These findings might contribute to our understanding of the ethnobotanical use of in wounds.
Steud()属于菊科。它在阿拉伯半岛的民间医学中有多种用途。本研究旨在评估 的提取物在大鼠中的伤口愈合特性。 提取物(5%或 20%)能成功促进细胞迁移,且无皮肤毒性迹象。 提取物的局部应用(5%或 20%)加速了大鼠切除皮肤的愈合。组织学检查表明, 缩短了上皮化期,刺激了成纤维细胞活性,并增加了伤口组织中的胶原蛋白沉积。植物提取物表现出抗氧化活性,这表现在抑制 GSH 耗竭和 MDA 积累以及增加实验结束时收集的伤口组织中 Sod1 的 mRNA 表达。此外, 抑制了 TNF-和 IL-1 在皮肤伤口区域的增加。通过观察到 Ptgs2、Nos2、IL-6 和 NF-B mRNA 表达的下调,证实了抗炎作用。此外,提取物增强了 TGF-1 和 HIF-1 在受伤皮肤组织中的表达,如免疫组化所示。总之, 加速了大鼠的切伤愈合。增强胶原蛋白、抗炎和抗氧化特性介导了观察到的伤口愈合活性。这些发现可能有助于我们理解 在伤口中的民族植物学用途。
