Abstract

Objectives: We evaluated the effects of glucosamine chondroitine sulphate (glcN-CS) on rat Achilles tendons in this experimental animal study. Materials and methods: Thirty Wistar albino type rats weighing 300-350 g were randomly grouped into two. Group A: Achilles tendons were tenotomized, repaired and, glcN-CS given orally. Group B: Achilles tendons were tenotomized and repaired. All the rats were fed with pellet chow. Five rats in each group were sacrificed at 4, 8, and 12 weeks interval. Tensile strength of three tendon specimen from each group were tested biomechanically and two specimen were analysed histopathologically via immunohistochemical staining and hematoxylin and eosin staining. Contralateral side Achilles tendons were also grouped and analyzed as controls (group C and D). Results: Histological results showed well organized collagen formation and less inflammation in group A. Biomechanical testing showed higher tendon strength in group A at eight weeks which is not statisticaly significant (55.3±4.84N, p=0.078). Rats which were were given glcN-CS had greater tendon strength which is statisticaly significant (50.01±5.62, p=0.014). Conclusion: Glucoseamine chondroitine sulphate improved results of Achilles tendon healing in rats. This result might be due to decreased inflammation and stimulation of collagen synthesis. Although glcN-CS is recommended only in osteoarthritic patients to relieve symptoms and signs it can also be prefered in treatment of soft tissue injuries formed during sports activities.

Özet

Amaç: Bu deneysel hayvan çalışmasında glukozamin kondroitin sülfatın (glcN-CS) sıçan Aşil tendonları üzerindeki etkisi değerlendirildi. Gereç ve yöntemler: Otuz adet 300-350 g ağırlığında Wistar albino türü sıçan rastgele iki gruba ayrıldı. Grup A: Aşil tendonları tenotomize edildi, tamir yapıldı ve glcN-CS ağızdan verildi. Grup B: Aşil tendonları tenotomize edildi ve tamir yapıldı. Bütün sıçanlar pelet yem ile beslendi. Her gruptan beşer sıçan 4, 8. ve 12. haftalarda sakrifiye edildi. Her gruptan üç adet tendon örneğinin gerilme gücü biyomekanik olarak test edildi ve iki örnek de immünohistokimyasal boyama ve hematoksilen ve eozin boyama yapılarak histopatolojik açıdan analiz edildi. Karşı taraf Aşil tendonları da gruplandırıldı ve kontrol olarak analiz edildi (grup C ve D). Bulgular: Histolojik sonuçlarda, grup A’da daha az enflamasyon ve daha düzgün kollajen oluşumu olduğunu görüldü. Biyomekanik testlerde 8. haftada A grubunda istatistiksel olarak anlamlı olmasa da daha yüksek tendon güçleri kayıt edildi (55±4.84N, p=0.078). Glukozamin kondroitin sülfat verilen hayvanlarda tendon gerilim güçleri istatiksel olarak anlamlı bir şekilde yüksek bulundu (50.01±5.62N, p=0.014). Sonuç: Glukozamin kondroitin sülfat sıçanlarda Aşil tendonu iyileşme sonuçlarını geliştirmiştir. Bu sonuç enflamasyonu azaltması ve kollajen sentezini uyarması ile ilişkili olabilir. Her ne kadar glcN-CS sadece osteoartriti bulunan hastalarda semptom ve belirtileri geriletmesi için önerilse de spor yaparken oluşan yumuşak doku yaralanmalarının tedavisi için de tercih edilebilir.
