Abstract

This experimental study was performed to determine the effects of intraarticular hyaluronic acid (HA) and methyl prednisolone acetate (MPA) in degenerative osteoarthritis. 0.2 ml 1% formaline were injected to the posterior right knee joints of 40 male rats. One week after the injections, 10 rats were killed and arthritis was determined histopathologically. The remained 30 rats were divided to three groups. First group received intraarticularly 0.05 ml HA (HA group), second group 0.05 ml MPA (MPA group) and third group 0.05 ml saline as controls. The injections were performed at 7., 14. and 21. days after the arthritis. 15 days after the end of these treatments, rats were killed and sections were examined histopathologically. There was no significantly difference in cartilage healing between MPA and control groups (p>0.05). However cartilage healing was significantly high in HA group compared to MPA and control groups (p<0.05). It was concluded that HA is more useful than MPA in the treatment of arthritis intraarticularly because of its positive effects on cartilage tissue.

Özet

Dejeneratif artritlerde intraartiküler olarak uygulanan hyaluronik asit (HA) ve metil prednisolon asetat (MPA) tedavilerinin etkilerini araştırmak için deneysel bir çalışma yapıldı. 40 adet erkek ratın sağ arka diz eklemleri içine 0.2 ml % 1 'lik formalin verilerek deneysel artrit oluşturuldu, ilaç verilmesinden bir hafta sonra 10 rat öldürülerek artritin oluştuğu histopatolojik olarak belirlendi. Kalan 30 rat 3 gruba ayrıldı. Birinci gruba 0.05 ml intraartiküler HA (HA grubu), ikinci gruba 0.05 mi intraartiküler MPA (MPA grubu) verildi. Üçüncü gruba ise intraartiküler 0.05 ml serum fizyolojik verilerek kontrol grubu oluşturuldu. Tedaviler artrit oluşturulduktan sonra 7. gün, 14. gün ve 21. gün uygulandı. Uygulanan bu tedavilerin bitiminden 15 gün sonra ratlar öldürüldü ve alınan örnekler, histopatolojik olarak incelendi. Yapılan incelemede; MPA grubunda kıkırdak iyileşmesi açısından kontrol grubuna göre anlamlı fark bulunamadı (p>0.05). HA grubunda ise kıkırdak iyileşmesi MPA ve kontrol grubuna göre anlamlı olarak yüksek bulundu (p<0,05). intraartiküler artrit tedavisinde kıkırdak dokusu üzerine olumlu etkilerinden dolayı HA'in MPA'a göre daha yararlı olduğu sonucuna varıldı.
