Abstract

Purpose: To determine the effect of NAC therapy on plasma levels, the protective role of tissue injury and organ dysfunction of free oxygen radicals in experimental sepsis model. Material and method: 30 female rabbits were divided into 3 groups, each composed of 10 rabbits. Sepsis was constituted by caeucum ligation perforation tecnique. Groups named sham, sepsis and sepsis + NAC (10mg/kg/day) were formed and medication was given I2and 24 hours after caeucum ligation and perforation. At the same time blood samples to measure blood gases, plasma glutathion/GSH), malondialdehyde(MDA) and biochemical diagnosis were collected. Tissue samples were obtained. Findings: Plasma GSH levels were elevated in NAC group with respect to sepsis group(P<0.05). Plasma MDA levels were decreased in sepsis group when compared to NACgroup(P<0.05). Liver tissue MDA levels were found to be same in both groups. AST, ALT and creatinine values were elevated significantly in NAC group when compared to sepsis group(P<0.05). Apoptosis in liver tissue was significantly decreased in NAC group when compared to sepsis group(P<0.05). Degree of mononuclear infiltration in kidneys were decreased in NAC group when compared to sepsis group(P<0.05). Conclusion: Application of low dose NAC, an antioxidative agent, in experimental sepsis model has beneficial effects on pulmonary functions and plasma MDA, GSH levels. More and comprehensive studies which tests different NAC doses are needed to determine the role for NAC in experimental sepsis model.

Özet

Deneysel sepsis modelinde N-asetilsistein'in (NAC) serbest oksijen radikalleri ve plazma düzeylerine olan etkilerini, organ fonksiyon bozuklukları ve doku hasarını önlemedeki rolünü belirlemektir. Materyal ve metod: 30 dişi tavşan 10'arlı gruplara ayrıldılar. Tavşanlarda çekum ligasyon perforasyon (ÇLP) yöntemiyle sepsis oluşturuldu. Sham grubu, sepsis grubu ve sepsis + NAC(lO mg/kg/gün) şeklinde gruplar oluşturulup, ilaçları ÇLP'den hemen sonra, 12.ve24. saatte verildi. Aynı saatlerde kan gazları, plazma glutatyon(GSH), malondialdehid(MDA), biyokimyasal tetkik için kan örnekleri alındı. Doku örnekleri alındı. Bulgular: Sepsis grubuyla kıyaslandığında NAC grubunda plazma GSH artmış (P<0.05) ve MDA değerleri azalmış bulundu (P<0.05). NAC grubunda SCOT, SGPT ve kreatinin değerleri sepsis grubuna göre artmıs bulundu (P<0.05). NAC grubunun arteriyel kan PO2 ve SaO2 degerleri sepsis grubuna göre artmıs bulundu (P<0.05). NAC grubunda karaciğerin histopatolojik incelemesinde apopitoz derecesi incelemesinde sepsis grubuna göre anlamlı düzeyde azalmıştı (P<0.05). NAC grubunun böbrekteki mononükleer hücre infiltrasyonu derecesi sepsis grubuna göre anlamlı düzeyde azalmış olarak bulundu (P<0.05). Sonuç: Deneysel sepsis modelinde antioksidan bir ajan olan NAC'in düşük doz uygulanmasında plazma MDA, GSH düzeylerine ve akciğer fonksiyonlarına olumlu etkileri mevcuttur. Daha kapsamlı ve yeni çalışmalarla NAC'in değişik dozlarda verilmesiyle sepsis tedavisinde NAC tedavisinin önemi daha iyi anlaşılacaktır.
