This experiment was conducted to evaluation the effects of different levels of untreated and treated green grape leaf with urea on performance, egg quality traits and blood parameters of laying hens. In this experiment 192 Hy-Line (w-36) laying hens, 35 to 46 wk of age were divided in to 4 treatments with 4 replicates (12 birds per replicate) in a completely randomized design experiment. The tr...

THE possibility of an error in the determination of urea in blood by urease methods was brought to our notice by the fact that figures obtained by the direct estimation of urea in human blood corpuscles were obviously too high. This error appears to have been first reported by Behre [1923], who observed that when the soya bean urease method was applied to whole blood the urea obtained was parti...

Doubt exists regarding the significance and diagnostic value of raised urea levels found in blood and cerebrospinal fluid after death. Harrison (1947), for instance, considers that in the present state of knowledge of post-mortem chemistry such estimations are without value, as high results are often obtained in moribund patients without kidney disease, and he also suggested that post-mortem ch...

The relationship of body condition score (BCS) and blood urea and ammonia to pregnancy outcome was examined in Italian Mediterranean Buffalo cows mated by AI. The study was conducted on 150 buffaloes at 145 +/- 83 days in milk that were fed a diet comprising 14.8% crude protein, 0.9 milk forage units.kg-1 dry matter and a non-structural carbohydrate/crude protein ratio of 2.14. The stage of the...

OBJECTIVES: Current nonendoscopic tests for Helicobacter pylori include antibody tests and the urea breath test. After the administration of C-urea, serum bicarbonate measurement can identify those infected with H. pylori. In this study, our aims were to determine the accuracy of the urea blood test, and to compare the accuracy of the urea blood test with that of rapid urease testing of gastric...

1. Glomerular filtration rate and effective renal blood-flow were normal in a series of patients with sickle cell anaemia. Fractional creatinine excretion and fractional urea excretion were increased. 2. During indomethacin administration there were significant falls in glomerular filtration rate, effective renal blood-flow, creatinine clearance and urea clearance in the patients with sickle ce...

In connection with other studies in this laboratory (1, 2),’ it became necessary to determine the concentration of urea in the blood of individual new-born rats. In view of the small quantities of blood available and the need for a considerable number of analyses, the calorimetric method developed by Archibald (3) appeared to be particularly suitable. This method is based upon the formation of ...

throughout the world, millions of muslims fast daily during the month of ramadan from sunrise (sahar) until sunset (iftar). considering the impacts of environment on physiological functions, we performed this study in order to examine the effects of ramadan fasting on some blood parameters of healthy volunteers and hypertensive patients. according to the results, there were no significant chang...

background: the purpose of our study was to determine the effect of n-acetylcysteine (nac) administered after successful cardiopulmonary resuscitation (cpr) on renal function of the survived patients. methods: in this double-blinded randomized clinical trial, 44 patients who experienced cardiopulmonary arrest and underwent successful cardiopulmonary resuscitation (cpr) were entered into the stu...
