Loop diuretics are used in patients with heart failure (HF) to relieve symptoms of systemic and pulmonary venous congestion. Despite their nearly universal use for this indication, loop diuretics have not been shown to improve survival—indeed, a number of recent studies suggest an adverse relationship between the use of loop diuretics and survival (1–3). This is plausible because loop diuretics...

The observation was made some 6 years ago that chickens were not poisoned by the parenteral injection of large quantities of crystalline urease, unless urea was also injected (1). However, rabbits were killed after urease was injected when the blood ammonia nitrogen reached a value of 5 mg. per 100 cc. (2). These observations offer sufficient evidence to make many of the values reported for ure...

lactatingdairy cows (n=177) fed with grass and corn silage ad libitum kept in pasture, were randomly assigned to evaluate how urea nitrogen in plasma and milk can be related to their pregnancy rate. blood and milk samples were collected on the artificial insemination (ai) day to evaluate plasma urea nitrogen (pun) and milk urea nitrogen (mun) as well as progesterone levels, excluding cows with ...

hydroalcoholic extract (70% ethanol extract) of tubers of momordica tuberosa cogn. (cucurbitaceae) was subjected to preliminary phytochemical screening by qualitative tests. nitric oxide scavenging activity was performed by griess reagent method. and nephroprotective activity was assessed in gentamicin, cisplatin and paracetamol induced renal damage in wistar rats (150-200 g) by standard method...

We compared results for urea concentrations in plasma and serum as measured with the Kimble Blood Urea Nitrogen Analyzer method as the test method with those determined by continuous-flow analysis (AutoAnalyzer 1 method) as the comparison method. We evaluated accuracy and precision for patients' samples, National Bureau of Standards Standard Reference Material, College of American Pathologists ...

The objective of this review is to describe recent research findings related to the use of milk or blood urea nitrogen to identify inefficiencies in protein nutrition and estimate nitrogen excretion. A mathematical model was developed to integrate milk urea nitrogen (MUN) and milk composition to predict urinary and fecal excretion, intake, and utilization efficiency for nitrogen in lactating da...

previous work by other investigators indicates a direct relation between the amount of protein in the diet and the level of urea in the blood . however, the present report shows that the type of protein , apart from its level in the ration , also has an effect on blood urea concentrations. when adult male or female rats of two strains were fed a ration in which the only source of protein was wh...
