Energy intake can determine albumin synthesis in man after surgery.

Albumin synthesis rate, nitrogen balance, plasma hormone levels, and selected substrates were measured after operation in 12 patients who underwent colonic operations who were randomized to receive an intravenous fluid regimen that contained either 3.5% amino acids with 20% fat and 2.5% glucose or 3.

Effect of isocaloric fat or glucose on albumin synthesis and nitrogen balance in patients receiving amino acid infusion.

Twelve patients who had undergone colon operations were randomized prospectively in the postoperative recovery room. Seven received a hypocaloric intravenous solution consisting of 3.5% amino acids plus 2.

Albumin synthesis and nitrogen balance in postoperative patients.

In a continuing prospective randomized study in a series of patients in the postoperative state, the rate of albumin synthesis was measured using the 14C carbonate technique. The majority of the patients studied were subjected to partial or total colectomy, and each patient was randomized to receive a hypocaloric intravenous regimen consisting of 3.5% amino acids (essential and nonessential) or 3.

Glutamate dehydrogenase, alanine aminotransferase, thymidine kinase, and arginase in fetal and adult human and rat liver.

In fetal livers of both man and rat thymidine kinase activity was 12 times higher than in the adult, glutamate dehydrogenase and arginase were present at 20-50% of their adult values, whereas alanine aminotransferase activity was only an insignificant fraction of that in the adult. Although the developmental changes for the four enzymes were quantitatively similar in both species, qualitatively there were some significant differences. In adult human liver, glutamate dehydrogenase activity was distributed almost equally between the cytosol and particles; the concentration of only the soluble enzyme increased after birth.
