Hemorrhoids are a common recto-anal disorder commonly known as piles or tissue clumps in the rectum. In normal individuals, they were known as anal cushions. In the anus, they are composed of rectal blood vessels, muscles, and elastic fibres. When bulged, it can cause bleeding, constipation, itching, severe pain, and bleeding in the anus. Inflammation of the anal cushion remains major pathogenesis for the development of hemorrhoids. Inflammatory mediators like neutrophils, TNF-α, and IL-6 seem to play a major role in the development of disease.
This study aims to carry out the ethanolic leaf extract of Lawsonia inermis (L. inermis) and evaluate its anti-hemorrhoidal activity both in vitro and in vivo. Furthermore, Molecular Docking was performed on the crystal structure of COX-2 with the selective compound 23d-(R) (PDB ID: 3NTG) protein.
The current study is to estimate an anti-inflammatory mediated anti-hemorrhoidal activity of ethanolic leaf extract of L. inermis at different doses of 200 mg/kg/ir and 400 mg/kg/ir in croton oil-induced hemorrhoidal rats. Pilex ointment is taken as a reference standard in the present study. Evan's blue extravasation technique were applied in the study to quantify the proinflammatory protein.
From the study results, a dose-dependent effect was found for ethanolic leaf extract of Lawsonia inermis at 200 mg/kg and 400 mg/kg causing a significant reduction of serum Proinflammatory mediators TNF-α, IL-6, and plasma neutrophils in croton oil-induced hemorrhoidal rats.
Studies represented that the plant extract can significantly inhibit protein denaturation of egg albumin in in vitro and found to reduce croton oil induced inflammatory mediators in hemorhhoidal rats.
痔疮是一种常见的直肠肛门疾病,通常被称为痔或直肠内的组织团块。在正常个体中,它们被称为肛垫。在肛门内,它们由直肠血管、肌肉和弹性纤维组成。当膨出时,可导致出血、便秘、瘙痒、剧痛和肛门出血。肛垫炎症仍然是痔疮发生发展的主要发病机制。中性粒细胞、肿瘤坏死因子-α和白细胞介素-6等炎症介质似乎在疾病发展中起主要作用。
本研究旨在对无患子(Lawsonia inermis)叶乙醇提取物进行研究,并评估其体外和体内的抗痔活性。此外,还对COX-2与选择性化合物23d-(R)(蛋白质数据银行编号:3NTG)的晶体结构进行了分子对接。
本研究旨在评估无患子叶乙醇提取物在200毫克/千克/腹腔注射和400毫克/千克/腹腔注射不同剂量下对巴豆油诱导的痔疮大鼠抗炎介导的抗痔活性。本研究以派尔克斯软膏作为参考标准。研究中应用伊文思蓝外渗技术来定量促炎蛋白。
从研究结果来看,在200毫克/千克和400毫克/千克剂量下,无患子叶乙醇提取物呈现出剂量依赖性效应,可使巴豆油诱导的痔疮大鼠血清促炎介质肿瘤坏死因子-α、白细胞介素-6以及血浆中性粒细胞显著减少。
研究表明,该植物提取物在体外可显著抑制卵清蛋白的蛋白质变性,并能降低巴豆油诱导的痔疮大鼠体内的炎症介质水平。
