Wall ex Benth. is a lemon-scented hoary shrub belonging to the mint family (Lamiaceae). Traditionally, a local tribe of the Himalayan region uses leaves for scabs and skin infections. The aerial parts and leaves are widely used to cure various skin ailments. The plant is well known for two furanoid diterpenes, royeleganin and royelegafuran. The aqueous extract of (AERE) leaves was investigated for wound-healing effects in rats using a physically induced burn model by assessing different parameters. Animals were divided into four groups (six rats in each group). Group I animals were considered as disease control and topically given base cream. Group II was considered as standard control and treated topically with Framycetin sulphate cream (1% w/w). Group III and IV animals were treated topically with creams containing 5 or 10% of AERE, respectively. Several parameters such as wound contraction rate, epithelialization period, and enzymatic and non-enzymatic antioxidant markers along with pro- and anti-inflammatory cytokines were studied followed by histopathological studies. The animals treated with AERE cream exhibited significant declination in the wound area and increased collagen content as compared to the disease control group. The results showed that the lower dose (5%) of AERE produced a significant decrease in the epithelialization period, wound contraction rate, and collagen content. Increased levels of cytokine production may be one of the mechanisms in accelerating the wound-healing process. The study established the traditional claim as an antioxidant and wound-healing potential of by promoting the accelerated wound-healing activity against the physically induced burn model.
Wall ex Benth.是一种有柠檬香味的灰白色灌木,属于唇形科(Lamiaceae)。传统上,喜马拉雅地区的一个当地部落用其叶子治疗结痂和皮肤感染。地上部分和叶子被广泛用于治疗各种皮肤病。该植物以两种呋喃类二萜——royeleganin和royelegafuran而闻名。通过评估不同参数,利用物理诱导烧伤模型研究了Wall ex Benth.(AERE)叶的水提取物对大鼠伤口愈合的影响。将动物分为四组(每组六只大鼠)。第一组动物被视为疾病对照组,局部给予基质乳膏。第二组被视为标准对照组,局部用硫酸新霉素乳膏(1% w/w)治疗。第三组和第四组动物分别用含有5%或10% AERE的乳膏局部治疗。研究了几个参数,如伤口收缩率、上皮化期、酶促和非酶促抗氧化标记物以及促炎和抗炎细胞因子,随后进行了组织病理学研究。与疾病对照组相比,用AERE乳膏治疗的动物伤口面积显著减小,胶原蛋白含量增加。结果表明,较低剂量(5%)的AERE可显著缩短上皮化期、伤口收缩率和胶原蛋白含量。细胞因子产生水平的增加可能是加速伤口愈合过程的机制之一。该研究通过促进针对物理诱导烧伤模型的加速伤口愈合活性,证实了Wall ex Benth.作为抗氧化剂和伤口愈合潜力的传统说法。
