Abstract

Zinc (Zn) is a trace element possessing a wide range of functions and antioxidant properties. This study was undertaken in order to illuminate the conflicting data on the status of zinc in diabetes, present in literature. Female Swiss albino rats were randomly divided into 4 groups: Group I, control; Group II, control + zinc sulfate; Group III, streptozotocin (STZ)-diabetic; Group IV, STZ-diabetic + zinc sulfate. Diabetes was induced by intraperitoneal injection of STZ (65 mg/kg body weight). Zinc sulfate was given daily by gavage at a dose of 100 mg/kg body weight every day for 60 days to Groups II and IV. At the last day of the experiment, rats were killed under anesthesia, kidney tissue was taken and homogenized. Antioxidant enzyme activities such as catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx), glutathione-S-transferase (GST), superoxide dismutase (SOD) and myeloperoxidase (MPO), were determined in tissue homogenates as well as protein carbonyl content (PCC). Carbonic anhydrase (CA) was also determined as a functional enzyme for kidney. It was shown that kidney tissue antioxidant enzyme activities which were significantly impaired in the untreated diabetic group, were reversed in zinc treated diabetic groups, thus showing the beneficial effect of Zn treatment in diabetes via its antioxidant effect.

Özet

Çinko (Zn), çok sayıdaki fonksiyonlarının yanı sıra antioksidan özellik de gösteren bir eser elementtir. Bu çalışma, bilimsel kaynaklarda, çinkonun diyabetteki etkisi ile ilgili çelişkili verileri aydınlatmak amacıyla gerçekleştirilmiştir. Swiss albino ırkı dişi sıçanlar 4 gruba ayrılmıştır: Grup I, kontrol; Grup II, kontrol + çinko sülfat, Grup III, streptozotosin (STZ)-diyabetik; Grup IV, STZ-diyabetik + çinko sülfat. Diyabet, intraperitoneal STZ (65 mg/kg) injeksiyonu ile oluşturulmuştur. Çinko sülfat, 60 gün süreyle, her gün 100 mg/kg oranında, gavaj yoluyla Grup II ve IV’e verilmiştir. Deneyin son gününde, sıçanlar anestezi altında kesildikten sonra böbrek dokuları alınarak homojenize edilmiştir. Doku homojenatlarında katalaz (CAT), glutatyon redüktaz (GR), glutatyon peroksidaz (GPx), glutatyon -S-transferaz (GST), superoksit dismütaz (SOD) ve miyeloperoksidaz (MPO) gibi antioksidan enzimlerin aktiviteleri ve protein karbonil miktarı (PCC) saptanmıştır. Ayrıca, böbrek için fonksiyonel bir enzim olan karbonik anhidraz (CA) aktivitesi de tayin edilmiştir. Diyabetik grupta anlamlı olarak değişiklik gösteren antioksidan enzim aktivitelerinin, çinko sülfat ile muamele edilmiş sıçanlarda iyileşme gösterdiği saptanmıştır. Sonuç olarak çinkonun diyabetteki olumlu etkisinin antioksidan etkisi nedeniyle olabileceği ileri sürülmüştür.
