Abstract

The role of free oxygen radicals and antioxidants in the pathogenesis of asthma, have not been well defined. In our study, we investigated plasma levels of free oxygen radicals and antioxidants in asthmatic patients. Symptomatic, mild asthmatic 18 patients who never used any antiasthma treatment (Group I, mean age, 34.6), asymptomatic, 20 mild asthmatic patients have been taking antiastma treatment (Group II, mean age, 35.1) and 20 healthy adults for control group (Group III, mean age, 33.2) were selected for this study. All cases were nonsmokers. In all selected cases, malondialdehyde (MDA), catalase (CAT), erytrhrocyte glutathione peroxidase (GPx), plasma seruloplasmine (SP) and vitamine C (Vit C) were measured. MDA and CAT levels of asthmatic patients in the Group I (respectively, 5.47±2.73 mol/L and 110.45±75.15 U/L) and in the Group II (respectively, 4.73±2.85 mol/L and 177.4±124.8 U/L) were significantly higher than control group (respectively, 2.14±0.66 mol/L and 42.54±21.97 U/L) (p<0.01), there was no significant difference between Group I and Group II (p>0.05). There was no statistically significant difference in GPx levels between three groups (p>0.05). SP levels of Group I (133.48±82.68U/L) were significantly higher than Group III (61.84±25.94U/L) (p<0.01), there was no difference between Group II (104.42±56.36U/L) and Group III (p>0.05). There was no statistically significant difference in Vit C levels between three groups (p>0.05). According to our study, oxidant and antioxidant substances were found higher in asthmatic patients than control group and it is concluded that, free oxygen radicals and antioxidants may play a role in pathogenesis of asthma.

Özet

Serbest oksijen radikalleri ve antioksidanların, astım patogenezindeki rolü henüz belirlenememiştir. Çalışmamızda, astımlı hastalarda ve kontrol grubunda serbest oksijen radikallerinin ve antioksidanların aktivitelerini araştırdık. Hiç astım tedavisi görmemiş, semptomatik, hafif astımlı 18 hasta (Grup I, yaş ortalaması, 34.6), halen tedavide olan asemptomatik hafif astımlı 20 hasta (Grup II, yaş ortalaması, 35.1) ve 20 sağlıklı birey kontrol grubu olarak (Grup III, yaş ortalaması, 33.2) çalışmaya alındı. Olguların hiçbiri sigara içmiyordu. Olguların, malondialdehid (MDA), katalaz (CAT), eritrosit glutatyon peroksidaz (GPx), plazma seruloplazmin (SP), ve C vitamini (Vit C) düzeyleri ölçüldü. MDA ve CAT ve düzeyleri, Grup I (sırasıyla, 5.47±2.73 mol/L,110.45±75.15 U/L) ve Grup II (sırasıyla, 4.73±2.85 mol/L, 177.4±124.8 U/L) olgularda, kontrol grubuna (sırasıyla, 2.14± 0.66 mol/L, 42.54±21.97 U/L) göre anlamlı olarak yüksekti, Grup I ve Grup II arasında ise istatistiksel olarak anlamlı fark yoktu (p> 0 .05). GPx düzeyleri bakımından her üç grup arasındaki fark, istatistiksel olarak anlamlı değildi (p>0.05). SP düzeyi Grup I'de (133.48±82.68U/L) kontrol grubuna (61.84±25.94U/L) göre anlamlı olarak yüksekti (p 0.05).VitC düzeylerinin her üç grup arasındaki farkı,istatistiksel olarak anlamlı değildi (p>0.05).Sonuç olarak,oksidan ve antioksidan maddelerin astımlı olgularda kontrol grubuna göre yüksek bulunması,serbest oksijen radikalleri ve antioksidanların astım patogenezinde rol oynayabileceğini göstermektedir.
