title: [Circadian aspects of iron metabolism. Changes of total iron binding capacity in patients with liver cirrhosis and in apparently healthy persons].
abstract: A group of 8 patients (M) with liver cirrhosis were studied. Each subject was standardized with rest time extending from 22,00 to 05,00 and meals scheduled at 08,00-08,30, 12,00-12,30, 17,30-18,00. Then was sampled at 04,00, 08,00 12,00, 16,00, 20,00, 24,00. In each sample of serum were determined iron, T.I.B.C. and L.I.B.C. All data were analyzed by macroscopic approach (chronograms) and by mean cosinor. A significant circadian rhythm was detected in all parameters, with a statistically valid difference between normal subjects and patients with liver cirrhosis in the mesor of T.I.B.C. and L.I.B.C.
