Ischemia Modified Albumin Levels in Spinal Cord Ischemia/Reperfusion Injury: an Experimental Study

Öz:
Giriş: Spinal kord iskemi/reperfüzyon hasarında iskemi nedenli oksidatif stres önemli yerteşkil eder. Ischemia-modifiye albumin (IMA), yeni kullanıma giren, iskemi ve oksidatif stresin duyarlı bir biyomarkırı olup, daha önce iskemik spinal kord hasarında çalışılmamıştır.Bu çalışmada deneysel spinal kord iskemi hasarında IMA düzeylerindeki değişikler incelendi.Metod: Elliüç adet yetişkin, erkek, 2,5-3 kg ağırlıklarında, Yeni Zelanda tavşanına aortoklüzyon metodu kullanılarak spinal kord iskemisi oluşturuldu. Denekler 10 gruba (sham,iskemi ve değişik zaman aralıklarında iskemi/reperfüzyon yapılan gruplar ve kontrolleri)ayrıldı.IMA, doku ve kan malondialdehyde (MDA) ve myeloperoxidase (MPO) aktivite düzeyleriylehistopatolojik hasar skorları karşılaştırıldı.Bulgular: IMA düzeylerinin iskemiyi takiben hızlı bir şekilde arttığı gözlemlendi.Reperfüzyonu takiben ise kontrol gruplarıyla aynı düzeye düştüğü izlendi. Serum IMAdüzeylerinin zamanla yükseldiği kontrol ve I/R grupları karşılaştırıldığında görüldü. AncakIMA düzeyleriyle kan ve doku MDA ve MPO düzeyleri arasında korelasyon tespit edilmedi(tüm kıyaslamalar için p>0,05). Histopatolojik skorlar ile serum IMA ve MDA düzeyleriarasında düşük korelasyon görüldü. Sonuçlar: Bu çalışmanın sonuçlarında spinal kordiskemi/reperfüzyon hasarında yüksek IMA düzeyleri tespit edildi. Yüksek IMA düzeylerininspinal kord iskemisinin ve komplikasyonun bir göstergesi olabileceği sonucuna varıldı.

Spinal Kord İskemi/Reperfüzyon Hasarında İskemi Modifiye Albumin düzeyleri: Deneysel Çalışma

Öz:
Background: Spinal cord ischemia/reperfusion (I/R) injury involves evident ischemia- mediated oxidative stress. Ischemia-modified albumin (IMA) has emerged as a novel andsensitive ischemia and oxidative stress biomarker, although it has not been previouslyinvestigated in ischemic spinal cord injury (SCI). This study was therefore intended toinvestigate serum IMA levels in a rabbit model of experimentally induced ischemic SCI.Method: Spinal cord ischemia was induced in 53 mature, male New Zealand rabbitsweighing 2.5-3 kg using the aortic occlusion model. Animals were divided into 10 groups(sham, ischemia and different duration I/R groups and their respective controls). IMA, tissueand blood malondialdehyde (MDA), tissue and blood myeloperoxidase (MPO) activity levelsand histopathological damage scores were then compared.Results: Ischemia-modified albumin levels rose rapidly when ischemia was induced to thespinal cord. They then declined to levels similar to those of the control groups whenreperfusion was established. Serum IMA levels exhibited a tendency to rise over time in boththe control and I/R groups compared to the sham group. We observed no correlation betweenIMA levels and blood and tissue MDA and MPO levels (p>0.05 for all correlations). Wedetermined only a low correlation between histopathological score and serum IMA and MDAlevels.Conclusions: The results from this pioneering study identified a high level of IMA in spinalcord I/R injury, indicating that IMA is a potentially valuable diagnostic or predictivetechnique for ischemic SCI and its complications.
