Abstract

Ischemia modified albumin is altered albumin by free radicals generated from ischemic tissues. Albumin cobalt binding assay is an indirect colorimetric assay of ischemia modified albumin. In this study we investigated effects of calcium (II), magnesium (II), iron (II), and copper (II) concentrations on the albumin cobalt binding assay. These cations were added into serum pools by increasing initial concentrations of 20, 50 and 100 %. Ischemia modified albumin was measured five times in these pools. Percent differences of absorbance values from the baseline absorbance values of ischemia modified albumin which were accepted 100 %. Percent differences from the baseline for calcium (II)- magnesium (II)- and copper (II)-spiked pools were as follows, respectively: at 20 % concentration increase: 115, 101, and 103 %; at 50 % concentration increase: 104, 101, and 125 %; at 100 % concentration increase: 107, 102, and 107 %. These deviations from the baseline were 97, 120, 109, 96 and 94 % at increased iron (II) concentration of 50, 100, 200, 300, and 400 %, respectively. In conclusion, albumin cobalt binding assay is not significantly affected by calcium (II), magnesium (II) and iron (II) concentrations but affected by copper (II).

Özet

İskemi modifiye albümin, iskemik dokulardan üretilen serbest radikaller ile değişikliğe uğrayan albümini, albümin kobalt bağlama testi ise iskemi modifiye albüminin indirekt kolorimetri yöntemi ile ölçümünü tanımlar. Çalışmamızda kalsiyum (II), magnezyum (II), demir (II) ve bakır (II) konsantrasyonunun albümin kobalt bağlama testi üzerine etkisini araştırdık. Başlangıç serum havuzlarına konsantre katyon çözeltileri eklenerek katyon konsantrasyonlarında % 20, 50 ve 100’lük artışlar sağlandı. Bu havuzlarda eş zamanlı olarak beşer kez iskemi modifiye albümin ölçümü yapıldı. Başlangıç havuzlarının absorbans değerleri ortalaması temel alınarak absorbans değerlerindeki yüzde değişim hesaplandı. Kalsiyum (II), magnezyum (II) ve bakır (II) için % 20 konsantrasyon artışı sırasıyla % 115, 101 ve 103; % 50 konsantrasyon artışı % 104, 101 ve 125; % 100 konsantrasyon artışı % 107, 102 ve 107 değişime neden oldu. Demir (II) için % 50, % 100, % 200, % 300, % 400 konsantrasyon artışı sağlanan çözeltilerde değişim sırasıyla % 97, % 120, % 109, % 96 ve % 94 idi. Sonuç olarak, albümin kobalt bağlama testi sonuçları kalsiyum (II), magnezyum (II) ve demir (II) konsantrasyonundan anlamlı ölçüde etkilenmezken; bakır (II) konsantrasyonundan etkilenmektedir.
