BACKGROUND/AIM: Ankaferd blood stopper (ABS) is a herbal extract that enhances mucosal healing. In this study, we aimed to investigate the efficiency of ABS in the treatment of experimental distal colitis.
Twenty one male albino rats were divided into three groups: Sham control (Group 1), colitis induced by acetic acid and treated with saline (Group 2), colitis induced by acetic acid and treated with ABS (Group 3). At end of the 7 th day of induction, all the rats were lightly anesthetized with intramuscular ketamine (8 mg/kg) and thereafter laparotomy and total colectomy were performed. The distal colon segment was assessed macroscopically and microscopically. In addition malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide (NO) levels of the colonic tissue and changes in body weight were measured.
The MDA and NO levels of the colonic tissues and weight loss were significantly higher in Group 2 compared to Group 1 and Group 3. Microscopic and macroscopic damage scores were significantly higher in Group 2 and Group 3 than Group 1 (P: 0.001, P: 0.004, respectively). Although the microscopic and macroscopic damage scores in Group 3 were slightly lower than Group 2, the difference was not statistically significant. The SOD levels of the colonic tissues were not different between the three groups.
Weight alterations and high-levels of the colonic tissue MDA and NO suggested that ABS might have anti-inflammatory effects on experimental distal colitis. However, this suggestion was not supported by histopathological findings.
背景/目的:安卡弗德止血剂(ABS)是一种促进黏膜愈合的草药提取物。本研究旨在探讨 ABS 治疗实验性远端结肠炎的疗效。
21 只雄性白化大鼠随机分为三组:假手术对照组(第 1 组)、乙酸诱导的结肠炎并用生理盐水治疗组(第 2 组)和乙酸诱导的结肠炎并用 ABS 治疗组(第 3 组)。在诱导的第 7 天结束时,所有大鼠均用肌肉注射氯胺酮(8mg/kg)轻度麻醉,然后进行剖腹术和全结肠切除术。评估远端结肠段的大体和显微镜下表现。此外,测量结肠组织丙二醛(MDA)、超氧化物歧化酶(SOD)和一氧化氮(NO)水平以及体重变化。
与第 1 组和第 3 组相比,第 2 组的结肠组织 MDA 和 NO 水平以及体重减轻显著更高。第 2 组和第 3 组的显微镜和大体损伤评分均明显高于第 1 组(P:0.001,P:0.004)。尽管第 3 组的显微镜和大体损伤评分略低于第 2 组,但差异无统计学意义。三组结肠组织的 SOD 水平无差异。
体重改变以及结肠组织 MDA 和 NO 水平升高提示 ABS 可能对实验性远端结肠炎具有抗炎作用。然而,这一推测并未得到组织病理学发现的支持。
