Abstract

Lipid peroxidation of important components of cellular membranes such as polyunsaturated fatty acids is caused by free oxygen radicals and is considered to be one of the main causes of hepatocyte injury. In order to investigate whether lipid peroxidation increases in acute viral hepatitis, plasma malondialdehyde (MDA) concentration was determined in 27 healthy subjects and in 36 patients suffering acute viral hepatitis. Plasma MDA levels were determined by fluorometric measurement of fluorescense intensity of MDA product and thiobarbituric acid reaction. Mean plasma MDA concentration was 0.822 ±0.533 µmol/L for the acute hepatitis A group (n=11), 1.836±0.515 µmol/L for the acute hepatitis B group (n=25), and 0.589±0.227 µmol/L for the control group. Plasma MDA levels of patients with acute hepatitis B were found to be higher than those in the control group and these differences were significant. (p<0.001). It is concluded that the increased MDA le-vels found in acute hepatitis B and C prove the increase in lipid peroxidation.

Özet

Hücre membranlarının önemli bir bileşeni olan poliansature yağ asitlerinin serbest oksijen radikallerine bağlı olarak lipit peroksidasyonunun, hepatosit zedelenmesinin ana nedenlerinden biri olduğu düşünülmektedir. Akut viral hepatitlerde lipit peroksidasyonunun artıp artmadığını araştırmak için, 27 sağlıklı kişide ve 36 akut viral hepatitli hastada plazma malondialdehit (MDA) düzeyleri belirlendi. Plazma MDA ölçümü MDA'nın tiyobarbitürik asit ile birleşmesi sonucu oluşan ürünün floresan şiddetinin florometrik olarak ölçülmesi esasına dayalı olarak yapıldı. Ortalama plazma MDA konsantrasyonları akut hepatit A grubunda (n=11) 0.822±0.533 µmol/L, akut hepatit B grubunda (n=25) 1.836±0.515 µmol/L, ve kontrol grubunda 0.589±0.227 µmol/L olarak saptandı. Akut hepatit B'li hastalarda plazma MDA düzeyleri kontrol grubuna göre daha yüksek saptandı ve bu fark istatistiksel olarak anlamlıydı (p<0.001). Sonuç olarak akut hepatit B'de MDA artışının saptanmasının lipit peroksidasyonunun arttığını gösterdiği görüşüne varıldı.
