Abstract

AIM: This study aimed to investigate the effects of VNS in transient middle cerebral artery occlusion and reperfusion (MCAO/R) rat model of ischemia based on behavioral, morphological, and molecular approaches. MATERIAL and METHODS: Wistar albino rats were divided into 3 groups: ischemia-reperfusion (I/R), I/R+VNS, and sham (for I/R). Each group was further divided into two subgroups for the assessment of neurological deficits and infarct area, or biochemical parameters related to oxidative stress. results: The infarct area and neurological scores were significantly lower in I/R+VNS group compared with the I/R group. MDA levels were significantly higher in I/R group compared to control and I/R+VNS groups in the cortical and subcortical specimens. There were also between- group differences in terms of GSH levels. GSH levels were higher in sham group compared with and I/R and I/R+VNS groups in cortical specimens whereas these levels for lower in I/R group compared to control and I/R+VNS groups in the subcortical specimens. SOD activity was higher in control group compared to I/R and I/R+VNS groups both in the cortical and subcortical specimens. There was no difference between I/R and I/R+VNS groups in neither cortical nor subcortical specimens. CONCLUSION: The neuroprotective and antioxidant properties of VNS suggest its efficacy as a potential anti-ischemic treatment.

Özet

AmAÇ: Bu çalışmada, sıçanlarda geçici orta serebral arterin oklüzyon (OSAo) modelinde vagus sinir uyarısının (VSU) etkilerini, davranışsal, morfolojik ve moleküler yaklaşımlar temelinde araştırmayı amaçladık. yÖntem ve GereÇler: Wistar Albino sıçanlar 3 gruba ayrıldı: iskemi reperfüzyon (I/R), sham (I/R için) ve I/R+VSU. Her bir grup kendi içinde nörolojik defisit ve infarkt alan ya da oksidatif stres ile ilişkili biyokimyasal parametreler değerlendirmek üzere iki alt gruba ayrıldı. BulGulAr: I/R grubuyla karşılaştırıldığında infarkt alanı ve nörolojik defisit skoru I/R+VSU grupta anlamlı şekilde düşüktü. MDA düzeyleri, kortikal ve subkortikal örneklerde I/R+VUS ve kontrol gruplarına göre I/R grubunda anlamlı şekilde yüksek bulundu. GSH düzeyleri açısından da gruplar arasında anlamlı fark vardı. GSH düzeyleri, kortikal örneklerde, sham grupta I/R ve I/R+VUS gruplarına göre yüksek iken, subkortikal örneklerde I/R grupta kontrol ve I/R+VUS gruplarına göre düşüktü. SOD aktivitesi, kortikal ve subkortikal örneklerde kontrol gruplarında I/R I/R+VUS gruplarına göre yüksek bulundu. sOnuÇ: Vagal sinir uyarısının nöron koruyucu ve antioksidan özelliği iskemi tedavisinde potansiyel etkinliğini göstermektedir.
