Abstract

AIM: The purpose of this study was to demonstrate the activity of agmatine, an inducible nitric oxide synthase (iNOS) inhibitor and selective N-methyl-D-aspartate receptor (NMDAR) antagonist, on reducing tissue damage in distal part of traumatic nerve in an experimental rat peripheral nerve injury model. MATERIAL and METHODS: Sciatic nerves of 30 Sprague Dawley male rats were used. Rats were divided into 5 groups; group 1 (n=6), control group; group 2 (n=6), axonotmesis + placebo group; group 3 (n=6), axonotmesis + 50 mg/kg agmatine treatment group; group 4 (n=6), neurotmesis + placebo group; group 5 (n=6), neurotmesis + 50 mg/kg agmatine treatment group. Axonolysis, axon degeneration, edema, hemorrhage, and inflammation were evaluated in histopathologic examinations of all the groups. RESULTS: When group 2 was compared with group 3 in histopathologic sections, axonolysis was less in group 3 (p=0.007), as was axon degeneration (p=0.022) and edema (p=0.018). When group 4 was compared with group 5, axonolysis was less in group 5 (p=0.009), as was axon degeneration (p=0.006) and edema (p=0.021). CONCLUSION: This study demonstrated agmatine to have antioxidant and antineurotoxic effects in an experimental rat peripheral nerve injury model.

Özet

AMAÇ: Bu çalışmanın amacı, indüklenebilir nitrik oksit sentetaz inhibitörü (iNOS) ve selektif N-metil-D-aspartat reseptörü (NMDAR) antagonisti olan agmatinin sıçanlarda yapılan deneysel periferik sinir yaralanma modelinde hasarlı sinirin distal bölumündeki doku hasarını azaltmadaki etkisini göstermekti. YÖNTEM ve GEREÇLER: Otuz tane Sprague Dawley sıçanının siyatik sinirleri kullanıldı. Sıçanlar beş gruba bölündü: birinci grup (n=6), kontrol grubu; ikinci grup (n=6), aksonotmezis + plasebo grubu; üçüncü grup (n=6), aksonotmezis + 50 mg/kg agmatin tedavi grubu; dördüncü Grup (n=6), neurotmesis + plasebo grubu; beşinci grup (n=6), neurotmesis + 50 mg/kg agmatin tedavi grubu. Aksonolizis, akson dejenerasyonu, ödem, hemoraji ve inflammasyon bütün gruplarda histopatolojik olarak değerlendirildi. BULGULAR: İkinci grup ile üçüncü grup histopatolojik kesitlerde kıyasladığında, aksonolizis üçüncü grupta daha azdı (p=0,007), aynı şekilde akson dejenerasyonu (p=0,022) ve ödem (p=0,018) üçüncü grupta daha azdı. Dördüncü grup ile beşinci grup histopatolojik kesitlerde kıyasladığında, aksonolizis beşinci grupta daha azdı (p=0,009), aynı şekilde akson dejenerasyonu (p=0,006) ve ödem (p=0,021) beşinci grupta daha azdı. SONUÇ: Bu çalışma, agmatinin sıçanlarda yapılan deneysel periferik sinir yaralanmalarında antioksidan ve antinörotoksik etkileri olduğunu göstermiştir.
