An increased excretion of nitrogen after injuries in experimental animals and in man was described by Cuthbertson (1930). In a series of papers he and his colleagues discussed and explored almost all the facets of this phenomenon which have since been studied (see, e.g., Cuthbertson, 1929, 1930, 1936, 1942; Cuthbertson & Tompsett, 1935 ; Cuthbertson, McGirr & Robertson, 1939). He investigated t...
The aim of this study was to evaluate the long-term (16-years) nitrogenefficiency after the application of organic and mineral fertilizers at two sitesLukavec (S1) and Suchdol (S2) with different soil and climatic conditions in theCzech Republic (Central Europe) and to determine grain yield and nitrogen contentwith regard to the requirements of protein content for baking quality of wheat.After ...
metabolizable protein (mp) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (rup) sources. effects on production efficiency and n utilization of early post-partum dairy cows were determined. forty-two multiparous and 16 primiparous holstein cows were assigned to the diets in a randomized complete block design immediately after part...
1. The effects of increasing glucose intake on nitrogen balance, energy expenditure and fuel utilization were measured in 12 malnourished adult patients receiving parenteral nutrition with constant, very high nitrogen intake (500 mg of N/kg), high (105 kJ/kg) or low (30 kJ/kg) glucose intake and constant fat intake (7 kJ/kg). Each patient received each diet for 8-day periods in random order. 2....
where UN0 is the excretion of urinary nitrogen on a protein-free diet and K is the nitrogen balance index of the dietary nitrogen (1). This is an equation for a straight line in regions of negative and low positive nitrogen balance where this balance is linearly related to absorbed nitrogen. Thus the index (K), which is the rate of change of nitrogen balance with respect to absorbed nitrogen, i...
Chemiluminescent measurement of total urinary nitrogen for accurate calculation of nitrogen balance.
This instrumental method for total urinary nitrogen (TUN) is based on the principle of gas-phase chemiluminescence. Results correlate well with measurements of TUN by the Kjeldahl method, which has long provided the means to calculate nitrogen balances for nutritional management. In recent years, because of speed and convenience of measurement, determination of urinary urea nitrogen (UUN) has b...
Adult dogs were given a proteinless diet plus casein, 80 calories/kilo, 0.4 gm. nitrogen/kilo/day. Sterile controlled inflammation was produced by subcutaneous injection of turpentine. The reaction is characterized by local swelling, induration, and abscess formation, terminated by rupture or incision after 3 to 5 days and by general reactions of malaise, fever, leucocytosis, and increased urin...
