In patients with renal insufficiency, the elevated plasma nonprotein nitrogen cannot be accounted for solely by the rise in the urea nitrogen (2). It is known that other nitrogenous materials such as creatinine and uric acid contribute to this elevation. Since free amino acids also contribute to the nonprotein, nonurea nitrogen of plasma, several investigators have determined the amino acid com...

milk urea nitrogen (mun) of dairy cows was determined in relation to breed. a total of forty (40) pabna and red chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. live weight of pabna cattle (187±14 kg) was higher than that of red chittagong cattle (174±4 kg). in pabna cattle milk yield (4.94 kg), minerals (0.15%) a...

Background: The purpose of this study was to ascertain the effects hot, dry spring and summer weather on endocrinological biochemical properties buffaloes with help physiological as well analysis. Methods: Like plasma glucose using GOD-POD kits, total protein Autospan Blood Urea Nitrogen MBK kits DAM assay, cortisol hormone by bovine enzyme linked immunosorbent assay kit etc. Result: During sea...

Fairley (1) proved by the results of glucose tolerance tests, and Barker and Rhoads (2) by fat tolerance tests, that the absorption of sugar and fat by patients with sprue is improved after treatment with liver extract. Moreover, Groen (3) observed that the diminished rate of absorption of glucose by the intestinal tract of 3 patients with pernicious anemia became normal after similar therapy. ...

An in vitro study was conducted using a 4 • 2 • 2 factorial design with RAC (readily available carbohydrate) levels of 30, 40, 50 and 60%, tallow levels of 0 and 3%, and urea levels of 0 and 2%. Acetic and propionic acid production and ammonia disappearance increased as the level of RAC increased from 30 to 50%. Tallow reduced acetic acid production and increased the amount of propionic acid pr...

Development within the cleidoic egg of birds and reptiles presents the embryo with the problem of accumulation of wastes from nitrogen metabolism. Ammonia derived from protein catabolism is converted into the less toxic product urea or relatively insoluble uric acid. The pattern of nitrogen excretion of the green iguana, Iguana iguana, was determined during embryonic development using samples f...

In mammals, the majority of nitrogen from protein degradation is disposed of as urea. Several studies have partly characterized expression of urea transporters (UTs) in hepatocytes, where urea is produced. Nevertheless, the contribution of these proteins to hepatocyte urea permeability (P(urea)) and their role in liver physiology remains unknown. The purpose of this study was to biophysically e...
