Popis: Serum Zn, ultrafiltrable Zn and amino acids in serum and urine samples of twenty-seven patients receiving cyclic (12 h/24 h) parenteral nutrition were measured. These samples were collected in patients after a 12 h period of parenteral nutrition, and in the evening after 12 h without parenteral nutrition. The same determinations were performed in ten control subjects who followed the same sampling scheme. Total serum ultrafiltrable Zn showed no significant variations in the patients during parenteral nutrition, and was not significantly different in the two groups although the proportion of the Zn present in the ultrafiltrable fraction was elevated. Serum cystine levels were significantly higher (P= 0·05) in the patients than the control subjects, and cystine excretion was also higher in patients (P< 0·05) and increased after parenteral nutrition (56·0 (SE 6·5)v. 147·1 (SE 20·6) m/12 h;P< 0·001). Histidine levels did not vary significantly in serum after parenteral nutrition and were not different in the patients in comparison with the control subjects. Histidine excretion was not different in the two groups but increased significantly during parenteral nutrition (P< 0·05). Serum albumin was significantly depressed in the patients compared with the control subjects (45·3 (SE 1·5)v. 33·9 (SE 1·5) g/l;P< 0·001). These results suggest that cystine infusion and excretion relate to the changes occurring in serum Zn and in urinary Zn excretion.
