Abstract
Background
Post-surgical tendon adhesion formation is a frequent clinical complication with limited treatment options. The aim of this study is to investigate safety and efficacy of orally administration of crocin in attenuating post-operative tendon-sheath adhesion bands in an Achilles tendon rat model.
Methods
Structural, mechanical, histological, and biochemical properties of Achilles tendons were analyzed in the presence and absence of crocin. Inflammation and total fibrosis of tendon tissues were graded between groups using macroscopic and histological scoring methods.
Results
Crocin significantly alleviated the severity, length, and density of Achilles tendon adhesions. Moreover, the recruitment of inflammatory cells and inflammation were significantly decreased in post-operative tissue samples of the crocin-treated group, as quantified with Moran scoring system. Histological results showed that crocin elicited a potent anti-fibrotic effect on tendon tissue samples as visualized by decreasing quantity, quality, grading of fibers, and collagen deposition at the site of surgery when scored either by Tang or Ishiyama grading systems. The H&E staining showed no histo-pathological changes or damage to heart, kidney, and liver tissues of treated rats.
Conclusion
Our results showed that crocin is a safe effective therapeutic candidate with potent anti-inflammatory and anti-fibrotic properties for adhesion band therapy post tendon surgery.
期刊介绍：
eJTCM is committed to publish research providing the biological and clinical grounds for using Traditional and Complementary Medical treatments as well as studies that demonstrate the pathophysiological and molecular/biochemical bases supporting the effectiveness of such treatments. Review articles are by invitation only.
eJTCM is receiving an increasing amount of submission, and we need to adopt more stringent criteria to select the articles that can be considered for peer review. Note that eJTCM is striving to increase the quality and medical relevance of the publications.
