Although burn wound management in medical practice has improved, the challenge still exists and demands multidisciplinary participation. Wheat has been extensively used as a remedy of different skin conditions especially burns in almost all parts of Italy. However, the mechanism is still unclear.
To examine the effects of different wheat bran extracts on the healing of burn wound estimated grossly, histopathologically, and immunologically.
Wistar male rats were divided into 5 groups; (control) saline treated group, Mebo (Moist Exposed Burn Ointment), cold-water extract, hot-water extract and methanolic extract groups. After the burn, four groups from the experimental groups were treated with Mebo, cold-water extract, hot-water extract and methanolic extract, respectively, but the negative-control group was treated daily with saline only. The observation was made along days 0, 5, 9, 13, 17 and 21. At the end of the study, rats were sacrificed, and blood samples were collected for biochemical and cytokines estimation in addition to wound samples were collected for histopathological and immunohistochemical studies.
The histopathological examination showed that the inflammation was significantly decreased in all extract-treated groups when compared with saline and Mebo-treated groups. Epithelial tissue and granulation tissue formation most significantly appeared in the cold water extract-treated group.
Cold water and methanolic extract groups showed the most rapid and effective healing of the burn wound. Particularly the cold-water extract, due to the sufficient concentration of zinc and phenolic components.
尽管医学实践中的烧伤创面管理已经得到改善,但仍然存在挑战,需要多学科参与。小麦已被广泛用作治疗各种皮肤状况的方法,特别是在意大利几乎所有地区的烧伤。然而,其机制尚不清楚。
从大体、组织病理学和免疫学方面研究不同麦麸提取物对烧伤创面愈合的影响。
将雄性 Wistar 大鼠分为 5 组;(对照组)生理盐水处理组、美宝(湿润烧伤膏)、冷水提取物、热水提取物和甲醇提取物组。烧伤后,实验组的 4 组分别用美宝、冷水提取物、热水提取物和甲醇提取物治疗,但阴性对照组每天只用生理盐水处理。观察在第 0、5、9、13、17 和 21 天进行。研究结束时,处死大鼠,采集血液样本进行生化和细胞因子评估,并采集创面样本进行组织病理学和免疫组织化学研究。
组织病理学检查显示,与生理盐水和美宝处理组相比,所有提取物处理组的炎症均明显减轻。冷水提取物处理组的上皮组织和肉芽组织形成最为明显。
冷水和甲醇提取物组显示出烧伤创面最快、最有效的愈合。特别是冷水提取物,由于锌和酚类成分的浓度足够高。
