Abstract

AIM: The objective of this study was to investigate the antifibrotic effect of parenteral administration of alpha-lipoic acid (ALA), which has been reported to reduce fibrosis in the liver, oral mucosa, and peritoneum, in laminectomized rabbits as a potential candidate for the prevention of peridural fibrosis. MATERIAL and METHODS: Twelve adult New Zealand white male rabbits were divided into control (n=6) and ALA treatment groups (n=6). Laminectomy of the lumbar spine was performed in all animals, and ALA was administered intramuscularly in six rabbits composing the treatment group. Total RNA obtained from the paraffin-embedded tissues was analyzed for transforming growth factor-β1 (TGF-β1), platelet- derived growth factor (PDGF), plasminogen activator inhibitor-1 (PAI-1) and interleukin-6 (IL-6). RESULTS: mRNA investigations showed that TGF-β1, PDGF, PAI-1 and IL-6 gene expressions, which constitute strong evidence for the development of fibrosis, were significantly lower in the treatment group compared with the results obtained from the control group. According to the histological peridural grading, the ALA-treated group showed significantly less peridural fibrosis than the control group. CONCLUSION: Intramuscular administration of ALA is a promising treatment for the prevention of peridural fibrosis in the postoperative period.

Özet

AMAÇ: Çalışma, daha önce karaciğer, oral mukoza ve periton fibrozisini önlediği bildirilen alfa lipoik asidin (ALA) peridural fibrozisin önlenmesinde kullanılabileceği düşüncesi ile laminektomi yapılan tavşanlarda parenteral uygulamadan sonraki antifibrotik etkisini araştırmak için yapılmıştır. YÖNTEM ve GEREÇLER: On iki yetişkin beyaz erkek Yeni Zelanda tavşanı kontrol (n=6) ve ALA-deney (n=6) grupları olarak ikiye ayrıldı. Bütün hayvanlarda laminektomi yapıldı ve deney grubunu oluşturan 6 tavşana intramüsküler ALA uygulandı. Parafine konulmuş olan dokulardan elde edilen RNAdan transforme edici büyüme faktör-β1 (TGF-β1), platelet-kaynaklı büyüme faktörü (PDGF), plasminojen aktivatör inhibitor-1 (PAI-1) ve interlökin-6 (IL-6) analizleri yapıldı. BULGULAR: mRNA RT-PCR sonuçları fibrozis oluşumunda güçlü delil olan TGF-β1, PDGF, PAI-1 ve IL-6 gen ekspresyonlarının deney gruplarında kontrol gruplarına göre anlamlı şekilde düşük olduğunu gösterdi. Histolojik peridural fibrozis sınıflandırılmasına göre de deney grubunda kontrol grubuna göre çok daha az fibrozis oluşmuştu. SONUÇ: İntramüsküler ALA uygulaması, postoperatif dönemde fibrozisin önlenmesinde ümit vadeden bir yöntem olarak dikkati çekmektedir.
