Psoriasis is a proliferative inflammatory skin disorder with relapsing episodes. Herein, the efficacy of babchi oil (BO) loaded nanostructure gel was evaluated for antipsoriatic activity and oxidative stress biomarkers assessment using mouse tail model. BO was entrapped into cyclodextrin-based nanocarriers (360.9 ± 19.55 nm), followed by incorporation into Carbopol gel and characterised for viscosity, spreadability, and texture analysis. The gels were topically applied on mouse-tails once daily for fourteen days. Evaluation of antipsoriatic activity as determined by histopathological observations of orthokeratotic epidermis revealed two times higher efficacy of BO nanogel in comparison to the native BO gel. Further, significantly enhanced superoxide dismutase (SOD) and reduced glutathione (GSH) levels, and diminished malondialdehyde (MDA) and nitrite (NO) levels revealed that prepared nanogels played a major role in the management of reactive oxygen species (ROS) associated in psoriasis pathogenesis. Hence, this study provides strong evidence for use of cyclodextrin-based nanogels as a safe and better delivery carrier of BO for management of psoriasis.
银屑病是一种复发性炎症性皮肤疾病。在此,通过小鼠尾模型评估了负载巴豆油的纳米结构凝胶的抗银屑病活性和氧化应激生物标志物评估。将巴豆油包封到环糊精基纳米载体中(360.9±19.55nm),然后掺入卡波姆凝胶中,并对其粘度、铺展性和质地分析进行了特征描述。凝胶每天在小鼠尾巴上涂抹一次,共 14 天。通过对角化表皮的组织病理学观察评估抗银屑病活性,结果显示,与天然巴豆油凝胶相比,巴豆油纳米凝胶的疗效高出两倍。此外,超氧化物歧化酶(SOD)和还原型谷胱甘肽(GSH)水平显著升高,丙二醛(MDA)和亚硝酸盐(NO)水平降低,表明制备的纳米凝胶在管理与银屑病发病机制相关的活性氧(ROS)方面发挥了重要作用。因此,这项研究为使用基于环糊精的纳米凝胶作为巴豆油的安全且更好的给药载体,用于治疗银屑病提供了有力证据。
