Résumé

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

Résumé

To investigate the effect of Ankaferd Blood Stopper [ABS], on renal tubular apoptosis and on expressions of endothelial nitric oxide synthase [eNOS], inducible nitric oxide synthase [iNOS], and apoptosis protease-activating factor-1 [Apaf-1] in the ipsilateral kidney after an experimentally formed partial nephrectomy in a rat model. The study was performed in 2009 at the Ankara Training and Research Hospital, Animal Laboratory Center, Ankara, Turkey. We divided 24 Wistar rats into the following 4 groups. Group I [GI] - partial nephrectomy [PN] with hilar control as the conventional technique, Group II [GII] - the conventional technique with ABS, Group III [GIII] - received ABS application to the renal parenchyma and collecting duct with hilar control [non-sutured group]. Group IV [GIV] - PN and ABS were performed without hilar control. The ABS solution [1 cc] was applied during the surgery to stop bleeding from resected renal tissue. At first month, all rats were sacrificed. Renal tubular apoptosis was investigated. The mean percentage of apoptotic cell counts in GI were 20% iNOS, 20% eNOS, and 10% Apaf-1. In GII they were 10% iNOS, 20% eNOS, 5% Apaf-1, in GIII they were 40% iNOS, 50% eNOS, 30% Apaf-1, and in GIV they were 5% iNOS, 5% eNOS, and 3% Apaf-1. There was no significant decrease in apoptotic cells in GII, GIII, and GIV, to which we applied ABS. The highest percentage of apoptosis was shown in GIII accompanied by significant inflammation. The lowest percentage was determined in GIV, the non-warm ischemia group. The ABS has a dual biphasic de novo effects on apoptosis. The challenge of severe hemorrhage in the renal tubular cellular micro-environment causes ABS-induced down-regulations in the expressions of apoptotic molecules, indicating that ABS may act as a topical biological response modifier
