Abstract

Objectives: Obesity has become an important publichealth problem because of its increasing prevalence andrelation with many diseases and mortality. Studies haveshown its association with oxidative stress. In this study,the effect of obesity on total amount of thiol and someglutathione S-transferase (GST) isozymes were investigatedwhich could serve as an important criteria in doseadjustment of some certain drugs in obese.Methods: The gastric tissues removed by gastrectomyoperation from 29 morbid obese female patients were analysedfor thiol levels and activities of total GST, GSTT1-1 andGSTM1-1. Patients were grouped according to age, presenceof hypertension and/or diabetes, and family history.Results: The average total thiol was 131.22 (±7.74) nmol/mg protein with no significant differences in between thegroups. GSTT1 specific activities were about 20% higher infour groups: with ages over 35 years old, with hypertension,without diabetes and finally without family history,with respect to other groups. The differences between totalGST and GSTM1 activity levels of experimental groups werenot significant.Conclusions: This is the first study to compare activities ofGST isozymes and total thiol content in the stomach tissuesof obese female patients accompanying some commonmetabolic disorders, age and family history.

Özet

Amaç: Obezite, artan yaygınlığı ve birçok hastalık ve ölümle ilişkisi nedeniyle önemli bir halk sağlığı sorunu haline gelmiştir. Çalışmalar, oksidatif stres ile ilişkisini göstermiştir. Bu çalışmada, obezlerde bazı ilaçların doz ayarlamasında önemli birer kriter olabilen, obezitenin toplam tiyol miktarı ve bazı glutatyon S-transferaz (GST) izozimlerine etkisi araştırılmıştır. Yöntemler: 29 morbid obez kadın hastadan gastrektomi operasyonu ile çıkarılan mide dokuları tiyol düzeyleri ve toplam GST, GSTT1-1 ve GSTM1-1 aktiviteleri açısından analiz edilmiştir. Hastalar yaş, hipertansiyon ve/veya diyabet varlığı ile aile geçmişine göre gruplandırılmıştır. Bulgular: Ortalama toplam tiol 131.22 (± 7.74) nmol/mg protein olarak ölçülmüş ve gruplar arasında önemli bir fark gözlenmemiştir. GSTT1 özgül aktiviteleri dört grupta; 35 yaş üstü, hipertansiyonlu, diyabetsiz ve aile öyküsü olmayanlarda, diğer gruplara göre yaklaşık % 20 daha yüksektir. Deney gruplarının toplam GST ve GSTM1 aktivite düzeyleri arasındaki farklar anlamlı değildir. Sonuç: Bu, bazı yaygın metabolik bozukluklar, yaş ve aile öyküsü ilişikli obez kadın hastaların mide dokularındaki GST izozimlerinin aktivitelerini ve toplam tiyol içeriğini karşılaştıran ilk çalışmadır.
