Abstract

Aim: Vitamin C is an excellent antioxidant in biological systems. However, It is also widely used as a pro-oxidant. This paradoxical behavior results because it is an excellent reducing agent. As for carbon tetrachloride, the incidence of carbon tetrachloride-induced hepatotoxicity is reported to be on the increase. In this study, it is aimed to test, whether additional intake of different concentrations of vitamin C improves antioxidative protection on lipid peroxidation, alanine transaminase, aspartate transaminase, glutathione and protein oxidation levels in single dose carbon tetrachloride-treated male Wistar rats. Material and Method: Two control groups and four treatment groups totaly sixty Wistar albino rats were used in this study. The control groups were fed via oral route a placebo (4 ml of distilled water), while test groups 100 mg /kg, 200 mg/kg, 400 mg/kg and 800 mg/kg body weight of vitamin C in 4ml of distilled water was given via gastric intubation. Results: The administration of vitamin C for 40 days produced a significant decrease with increasing concentrations from 100 to 400 mg/kg of vitamin C in differnt parameters carbon tetrachloride-treated rats. But, the same protection was not observed at higher concentration of vitamin C. Moreover, it has showed hazardous activity at 800 mg/kg concentration as much as carbon tetrachloride-induced toxicity. Discussion: These results showed that vitamin C had not the potential to be used as tissue protective agent at higher doses. Also, results suggest that the same substannces that optimizes antioxidant capacity may also act as prooxidant dependent on its concentration.

Özet

Amaç: C vitamini biyolojik sistemlerdeki mükemmel bir antioksidandır. Ancak, C vitaminin prooksidan madde olarak kullanımı da yaygındır. Bu çelişkili olgu C vitamininin mükemmel bir indirgeyici madde olmasından kaynaklanmaktadır. Diğer yandan, Karbon tetraklorüre baktığımızda, karbon tetraklorür uygulamasına bağlı hepatotoksisite insidansnda artış olduğu bildirilmektedir. Bu çalışmada, tek doz karbon tetraklorür uygulanmış erkek Wistar türü sıçanlarda farklı dozlardaki C vitamininin lipid peroksidasyonu, alanin transaminaz, aspartat transaminaz, glutatyon ve protein oksidasyon düzeylerine pozitif bir etkisinin olup olmadığı araştırıldı. Gereç ve Yöntem: İki kontrol grubu ve dört tedavi grubu olmak üzere 6 grup ve toplamda altmış Wistar albino sıçan kullanıldı. Deney gruplarına sırasıyla 4 ml distile su içinde 100 mg / kg, 200 mg / kg, 400 mg / kg ve 800 mg / kg C vitamini verilirken kontrol gruplarına oral yoldan gastrik entübasyon ile 4 ml distile su verilmiştir. Bulgular: 40 gün boyunca yapılan uygulama sonunda 100 ile 400 mg / kg arasındaki artan C vitamini konsantrasyonları, karbon tetraklorür ile muamele edilen erkek Wistar sıçanların farklı biyokimyasal parametreleri üzerinde önemli bir koruma ve azalma sağlamıştır. Ancak, aynı koruma C vitamininin 800 mg / kg konsantrasyonunda gözlenmemiştir, Üstelik bu konsantrasyondaki C vitamini karbon tetraklorür tarafından uyarılan toksik etki kadar zaralı bir etki göstermiştir. Tartışma: Bu sonuçlar, yüksek dozlardaki C vitamininin doku koruyucu bir madde olarak kullanılmasının uygun olmadığını göstermiştir. Ayrıca, sonuçlar antioksidan olduğu bilinen bir maddenin, doza bağlı olarak prooksidan madde gibi hareket edebileceğini düşündürmektedir.
