Abstract

To determine whether tobacco use is associated with certain alterations involving antioxidant system and some of its related parameters 50 subjects who have been smoking more than a pack of cigarette per day for at least five years and 50 healthy individuals who had never smoke in their life were examined. Serum catalase, erythrocyte superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and glucose 6-phosphate dehydrogenase (G6PD) activities, and malondialdehyde (MDA) concentration in both serum and erythrocyte of all subjects were measured. Periferic blood count, serum uric acid, and albumin levels were also measured. In comparison with the non smokers, catalase and GSH-Px enzyme activities were found significantly lower in the smokers while SOD and G6PD activities were not significantly different. In addition, MDA was found significantly higher in both serum and erythrocytes (p 0.05), hemoglobin (Hb) and white blood cells (WBC) were found higher (p< 0.01 and p< 0.001, respectively). From these results, it can be suggested that antioxidants can be depleted against fighting with oxidants, or they can be inhibited by certain chemical compounds of cigarette smoke.

Özet

Sigara kullanımının antioksidan sistem ve ilişkili bazı parametrelerde değişikliklere neden olup olmadığının belirlenmesi amacıylı en az 5 yıldır günde bir paketten fazla sigara içen 50 birey ve hiç sigara içmemiş olan 50 sağlıklı birey incelendi. Tüm olgularda serum katalaz, eritrosit süperoksid dismutaz (SOD), glutatyon peroksidaz (GSH-Px), glukoz-6-fosfat dehidrogenaz (G6PD) enzim aktiviteleri ile serum ve eritrosit malondialdehit (MDA) düzeyleri araştırıldı. Ayrıca tam kan sayımı, ürik asit, albümin ve bilirübin düzeyleri çalışıldı. Araştırılan enzimlerden katalaz ve GSH-Px aktiviteleri, sigara içenlerde içmeyenlere göre anlamlı olarak düşük bulunurken, SOD ve G6PD aktivitelerinde her iki grup arasında anlamlı bir fark saptanmadı. Lipit peroksidasyon ürünü olan ve oksidatif hasarı gösteren MDA ise sigara içenlerde gerek serumda ve gerekse eritrositlerde anlamlı olarak yüksek bulundu (p 0.05), lökosit sayımı (p< 0.001) ve hemoglobin düzeyi anlamlı olarak (p< 0.01) daha yüksek bulundu. Bu sonuçlara dayanarak antioksidan bileşiklerin oksidanlara karşı koyarken baskılanmış olabileceği ya da sigara dumanının içerdiği bazı kimyasal bileşiklerce inhibe edilmiş olabilecekleri öne sürülebilir.
