Whole body protein synthesis measurement. Measurement of the rate of whole body protein synthesis from the specific activity of tissue amino acids at the end of the infusion may not provide a more reliable estima tion and in any case those measurements are not feasible. Rates of whole body protein synthesis and breakdown expressed as g proteinkg body weightday were significantly p less than 005 and positiviely correlated with per cent body surface area total burn per cent third degree burn and per cent open wound. N glycine as a tracer to study protein metabolism in vivo. Breakdown 63 18 g protein. Measurement of whole body protein turnover protein synthesis breakdown and net balance enables quantification of the response to a variety of circumstances including the response to meal feeding. Whole body net protein synthesis can be estimated by nitrogen balance.
Where whole body protein losses includes in proteins in eggs or molted feathers. The study was performed within two weeks of the initial burn and whole body protein synthesis and breakdown were higher in patients with 60 tbsa burned compared to patients with 25 tbsa burned or to control children undergoing reconstructive surgery. Plateau enrichment of 15n ammonia following 24 hour continuous intravenous infusion of 15n glycine was used to measure total body protein turnover and synthesis in normal volunteers and malnourished patients with and without cancer. Measurement of whole body protein content in vivo. 1981 etude de la synthse protrique in vivo dans le muscle de la truite arc en ciel salmo gairdneri r. Prediction of protein synthesis rate.
Whole body protein synthesis and breakdown were determined using repeated oral administration of 15 n glycine for 6072 h and 15 n enrichment in urinary urea was measured. F nce kino and okumura 1987 estimated nitrogen balance in 1421 day old chickens as 029 gday. Isotopic estimation of protein synthesis and proteolysis in vivo. In vivo protein synthesis in different tissues and the whole body of rainbow trout salmo gaidneri r. Determined whole body protein synthesis and breakdown rates more precisely by administering 15 n glycine orally or intravenously every 3 hours for 48 hours in acutely burned children. The number of termination events is a proxy to the actual number of proteins synthesized as long as protein degradation is negligible which is what we assume.
The remaining chapters discuss estimation of protein synthesis and proteolysis in vitro. If negative whole body protein net synthesis accretion is whole body protein net degradation. One of the desired outcomes of a translation model is a prediction of protein synthesis rate which is also a measure of translational efficiency. These rates synthesis 71 21 g proteinkgday. And mathematical models of protein metabolism. The mean postabsorptive total body protein synthesis rate in three normal controls was 25 g proteinkgday.
