In a previous paper,3) a colorimetric method for the determination of urea nitrogen in blood and urine was presented on the basis of a color reaction of urea with diacetyl monoxime (DAM) in phosphoric acid solution in the presence of D-glucuronolactone (GL), which served to produce a photo-stable color and eliminate the sigmoidal nature of calibration curve observed usually in the DAM method.4)...

The chemical findings in the blood of 6 dogs with closed-loop obstruction of the upper jejunum are reported. The duration of life with closed loops is less than with simple obstruction. All animals showed a marked rise in non-protein nitrogen and urea nitrogen, and fall in chlorides. Usually the C0(2) combining power of the plasma is increased. The findings in closed-loop obstruction are essent...

Diabetes mellitus was induced in 32 out of 40 adult male albino rats using intravenous injection of 50 mg/kg BW of alloxan. Then, the diabetic rats were divided into four groups, three of which fed a diet containing 8 % BW ethanol (polar solvent), cyclohexane (nonpolar solvent) and ether (intermediate solvent) extracts of walnut leaf for 21 days. The fourth (positive control) group received a n...

A study was carried out on 57 patients with chronic renal failure in a hospital in Kerman city, Islamic Republic of Iran. Blood samples were taken before and after haemodialysis to measure blood urea nitrogen and serum creatinine, triiodothyronine (T3) and thyroxine (T4) levels. Findings revealed that before dialysis T4 in 11 cases and T3 in 29 cases were lower than the normal range, but after ...

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...

Introduction Kidney disease (KD), including acute kidney injury, is common, severe and leads to significant mortality in the developing world. However, simple tools to facilitate diagnosis and guide treatment are lacking. We studied the diagnostic performance of saliva urea nitrogen (SUN) measured by dipstick to diagnose KD in a low-resource setting. Methods Medical admissions to a tertiary h...

Astragalus membranaceus is a famous Chinese medicinal herb. Polysaccharides are the most important functional constituent in Astragalus membranaceus. In the present study, the effects of Astragalus membranaceus polysaccharides (APS) on exercise endurance capacity were evaluated in mice using swimming exercise. The antioxidant properties of APS were also investigated through the 1,1diphenyl-2-pi...

A significant increase in blood urea was found in 11 U.S. Navy divers during 8 d of air saturation hyperbaric exposure. Similar increases in blood urea have been found in animals that convulsed during hyperbaric oxygen exposure. Therefore, it is suggested that careful attention be given to blood ammonia and urea levels in humans during long-term hyperbaric exposure.

STUDY OBJECTIVE To evaluate the effect of cardiac arrest and cardiopulmonary resuscitation (CPR) on blood chemistry in a canine model. DESIGN Evaluative canine animal study. SETTING Animal laboratory accredited by the Association for Assessment and Accreditation of Laboratory Animals. SUBJECTS Twenty-six adult mongrel dogs. INTERVENTION The dogs underwent an episode of induced fibrillat...
