Susceptibility to in vitro lipid peroxidation of low density lipoproteins and erythrocyte membranes from liver cirrhotic patients. Scand J Clin Lab Invest 1994; 54: 147-153.The aim of the present study was to investigate the susceptibility of low density lipoprotein (LDL) and red blood cell membranes (RCM) from liver cirrhotic patients and control subjects, to the peroxidative stress, induced in vitro by phenylhydrazine. The susceptibility to peroxidation was determined by measuring the formation of the thiobarbituric acid reactive substances (TBARS) after incubation with phenylhydrazine. Moreover the levels of cholesterol (C) and phospholipid (PL) were evaluated in plasma and isolated LDL and RCM. A significant decrease in plasma C, LDL-C and RCM-C content (p < 0.001, p < 0.01 and p < 0.05 respectively) and RCM-PL content (p < 0.01) were found in cirrhotic patients compared to controls. The lower susceptibility to in...
