Abstract

The aim of this study is to investigate the expected adhesion-modifying effect of clinoquinol which has metal-chelating feature that limits the inflammation and fibroblastic activity.A total of 40 Wistar Albino rats were included, which were divided into 5 groups. Group-1 constituted the sham group. Other groups, adhesions were induced by performing cecal abrasion on the rats. For treatment, saline solution was added to Group-2, carboxymethylcellulose was added to Group-3, methylene blue was added to Group-4, and clioquinol was added to Group-5. Blood samples were obtained from the heart to measure IL-10 and TNF α-levels. Adhesions were evaluated both macroscopically and histopathologically.Clioquinol reduced adhesions at significant level via decreasing the inflammation and fibroblastic activity in the adhesion-induced rats. At macroscopic level, carboxymethylcellulose and clioquinol were the most potent agents in reducing adhesions. Nonetheless, significant foreign body-reaction was observed in the carboxymethylcellulose-treated group.Clioquinol could reduce the formation of intra-abdominal adhesions. It exerts this activity by limiting the inflammation and fibroblastic activity between the intestines and serous surfaces. Furthermore, it does not induce a foreign body reaction. Due to these properties, we conclude that clioquinol can be used as an alternative agent to prevent adhesions.Copyright © 2015 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.
