Farklı yaş ve cinsiyetteki Ankara kedilerinde kan ağır metal konsantrasyonlarının ve oksidan-antioksidan kapasitelerinin belirlenmesi

Abstract

Bu çalışma, farklı yaş ve cinsiyetteki Ankara kedilerinde ağır meta konsantrasyonlarını ile plazma ve eritrositlerin oksidatif stres durumunu araştırmak için yapıldı. On altı yavru (1 yaşından küçük) ve 14 yetişkin (1-6 yaş) kedi aynı zamanda cinsiyete göre erkek (n=17) ve dişi (n=13) olarak gruplandırıldı. Kedilerin kanından ayrıştırılan plazma örnekleri seçilen ağır metaller ve toplam oksidan ve antioksidan kapasiteler (TOC ve TAC) için analiz edildi ve oksidatif stres endeksi (OSI) için hesaplandı. Eritrosit hemolizatlarından ise, malondialdehit (MDA), süper oksit dismutaz (SOD), katalaz (CAT) ve glutatyon peroksidaz (GPX) açısından değerlendirildi. Çalışmanın sonuçları, ölçülen metallerin çoğunun yaş veya cinsiyete göre istatistiksel olarak değişmediğini gösterdi. Bununla birlikte, yetişkin kedilerde yavrulara göre Cu’nın önemli derecede (P<0.01) yüksek, Fe’nin ise daha düşük olduğu belirlendi. Gençlerdeki plazma TOC, TAC ve OSI seviyeleri ile MDA konsantrasyonları yetişkinlere göre anlamlı derecede yüksekti (P<0.05). SOD aktivitesi yaşla birlikte azalırken, GPX aktivitesi arttı (P<0.05). Ancak, erkeklerde daha yüksek olan CAT aktivitesi sadece cinsiyete göre değişti (P<0.01). Sonuç olarak, metallerin özellikle iz elementlerinin birçok fizyolojik süreç için ve antioksidan enzimlerinin sentezi için gerekli olduğu iyi bilinmektedir. Bu nedenle, metallerin periyodik ölçümünün ve yetişkin Ankara kedilerinin diyetine yaygın antioksidan takviyelerinin eklenmesi yaşla birlikte zayıflayan antioksidan mekanizmaların desteklenmesi açısından önerilebilir.

Determination of blood heavy metal concentrations and oxidant-antioxidant capacities in Angora cats at different age and gender

Abstract

This study was conducted to investigate heavy metal concentrations and oxidative status of plasma and erythrocytes in Angora cats at different ages and gender. Sixteen young (less than 1 year old) and 14 adult (1–6 years old) cats were also grouped according to gender as male (n = 17) and female (n = 13). The separated plasma samples from cat’s blood were analyzed for selected heavy metals and total oxidant and antioxidant capacities (TOC and TAC) and calculated for oxidative stress index (OSI). The erythrocyte hemolysates were also evaluated for malondialdehyde (MDA), and super oxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX). Results of the study showed that most of the measured metals were not varied statistically according to age or gender. However, adult cats had significantly (P<0.01) higher Cu and lower Fe levels compared to young cats. Plasma levels of TOC, TAC and OSI, and erythrocyte MDA concentrations in young cats were significantly (P<0.05) higher than that of adults. While the SOD activity was decreased by the age, GPX activity was increased (P<0.05). However, the activity of CAT was changed by only gender, which was higher in males (P<0.01). In conclusion, metals, especially trace elements, are required for many kinds of physiological processes and the synthesis of antioxidant enzymes. Therefore, it can be suggested that the periodic measurement of metals and the addition of common antioxidant supplements to the diet of adult Angora cats will support weakening antioxidant mechanisms by age.
