The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.

Effect of fasting on temporal variation in the nephrotoxicity of amphotericin B in rats. (1/1427)

Evidence for temporal variation in the nephrotoxicity of amphotericin B was recently reported in experimental animals. The role of food in these variations was determined by studying the effect of a short fasting period on the temporal variation in the renal toxicity of amphotericin B. Twenty-eight normally fed and 28 fasted female Sprague-Dawley rats were used. Food was available ad libitum to the fed rats, while the fasted animals were fasted 12 h before and 24 h after amphotericin B injection to minimize stress for the animals. Water was available ad libitum to both groups of rats, which were maintained on a 14-h light, 10-h dark regimen (light on at 0600 h). Renal toxicity was determined by comparing the levels of excretion of renal enzyme and the serum creatinine and blood urea nitrogen (BUN) levels at the time of the maximal (0700 h) or the minimal (1900 h) nephrotoxicity after the intraperitoneal administration of a single dose of dextrose (5%; control group) or amphotericin B (50 mg/kg of body weight; treated group) to the rats. The nephrotoxicities obtained after amphotericin B administration at both times of day were compared to the nephrotoxicities observed for time-matched controls. In fed animals, the 24-h urinary excretion of N-acetyl-beta-D-glucosaminidase and beta-galactosidase was significantly higher when amphotericin B was injected at 0700 and 1900 h. The excretion of these two enzymes was reduced significantly (P < 0.05) in fasting rats, and this effect was larger at 0700 h (P < 0.05) than at 1900 h. The serum creatinine level was also significantly higher (P < 0.05) in fed animals treated at 0700 h than in fed animals treated at 1900 h. Fasting reduced significantly (P < 0.05) the increase in the serum creatinine level, and this effect was larger in the animals treated at 0700 h. Similar data were obtained for BUN levels. Amphotericin B accumulation was significantly higher (P < 0.05) in the renal cortexes of fed rats than in those of fasted animals, but there was no difference according to the time of injection. These results demonstrated that fasting reduces the nephrotoxicity of amphotericin B and that food availability is of crucial importance in the temporal variation in the renal toxicity of amphotericin B in rats.  (+info)

Sustained induction of fetal hemoglobin by pulse butyrate therapy in sickle cell disease. (2/1427)

High levels of fetal hemoglobin (Hb F) protect from many of the complications of sickle cell disease and lead to improved survival. Butyrate and other short chain fatty acids were previously shown to increase Hb F production in erythroid cells in vitro and in animal models in vivo. However, butyrates are also known to inhibit the proliferation of many cell types, including erythroid cells. Experience with the use of butyrate in animal models and in early clinical trials demonstrated that the Hb F response may be lost after prolonged administration of high doses of butyrate. We hypothesized that this loss of response may be a result of the antiproliferative effects of butyrate. We designed a regimen consisting of intermittent or pulse therapy in which butyrate was administered for 4 days followed by 10 to 24 days with no drug exposure. This pulse regimen induced fetal globin gene expression in 9 of 11 patients. The mean Hb F in this group increased from 7.2% to 21.0% (P <.002) after intermittent butyrate therapy for a mean duration of 29.9 weeks. This was associated with a parallel increase in the number of F cells and F reticulocytes. The total hemoglobin levels also increased from a mean of 7.8 g/dL to a mean of 8.8 g/dL (P <.006). The increased levels of Hb F were sustained in all responders, including 1 patient who has been on pulse butyrate therapy for more than 28 months. This regimen, which resulted in a marked and sustained increase in Hb F levels in more than two thirds of the adult sickle cell patients enrolled in this study, was well tolerated without adverse side effects. These encouraging results require confirmation along with an appropriate evaluation of clinical outcomes in a larger number of patients with sickle cell disease.  (+info)

Comparative nephrotoxicities of netilmicin and gentamicin in rats. (3/1427)

The relative nephrotoxicities of netilmicin (Sch 20569) and gentamicin were compared in rats at doses of 30, 60, 90, and 120 mg/kg per day for 15 days. Both drugs caused proteinuria and a decrease in urine osmolality; however, netilmicin produced significantly less changes at all doses than gentamicin. Whereas gentamicin resulted in a decline in creatinine clearance at all doses, netilmicin failed to cause a decline in creatinine clearance. Renal-cortical concentrations of antibiotic at sacrifice were similar in animals receiving either drug. Light-microscopic changes were less severe with netilmicin than gentamicin. Cytosegresomes with myeloid bodies were identified electron microscopically in the kidneys of animals receiving either netilmicin or gentamicin at all doses. Electron-microscopic manifestations were similar. The data indicate that in the rat, netilmicin is distinctly less nephrotoxic than gentamicin.  (+info)

Total parenteral nutrition in the management of acute renal failure. (4/1427)

Malnutrition is frequently present in patients with acute renal failure and may affect morbidity and mortality in this condition. When adequate nourishment cannot be given through the gastrointestinal tract, total parental nutrition with amino acids and hypertonic glucose may have beneficial results. Total parenteral nutrition has been reported to stabilize or reduce serum urea nitrogen, potassium and phosphorus levels, improve wound healing, enhance survival from acute renal failure, and possibly increase the rate of recovery of renal function. The optimal composition of the total parenteral nutrition infusate is unknown. Preliminary results of a double-blind study are reported in which one man received hypertonic glucose alone, two received glucose with essential amino acids (21 g/day), and three received glucose with essential (21 g/day) and nonessential (21 g/day) amino acids. All infusates were isocaloric. No differences were observed in serum urea nitrogen levels, serum urea nitrogen/creatinine ratios or urea appearance rates. Nitrogen balance was negative in all patients. The ratio of essential amino acids/nonessential amino acids were higher and the tyrosine/phenylalanine ratios were lower in plasma in the two patients receiving glucose with essential amino acids. No patient survived the hospitalization. In view of the markedly negative nitrogen balance frequently observed in these and earlier studies, the use of a different composition or quantity of amino acids, a higher energy intake, and anabolic hormones deserve further investigation.  (+info)

Measurement of the delivery of dialysis in acute renal failure. (5/1427)

BACKGROUND: Recent studies in patients with acute renal failure (ARF) have shown a relationship between the delivered dose of dialysis and patient survival. However, there is currently no consensus on the appropriate method to measure the dose of dialysis in ARF patients. In this study, the dose of dialysis was measured by blood- and dialysate-based kinetic methods in a group of ARF patients who required intermittent hemodialysis. METHODS: Treatments were performed using a Fresenius 2008E volumetric hemodialysis machine with the ability to fractionally collect the spent dialysate. Single-, double-pool, and equilibrated Kt/V were determined from the pre-, immediate post-, and 30-minute post-blood urea nitrogen (BUN) measurements. The solute reduction index was determined from the collected dialysate, as well as the single- and double-pool Kt/V. RESULTS: Forty-six treatments in 28 consecutive patients were analyzed. The mean prescribed Kt/V (1.11 +/- 0.32) was significantly greater than the delivered dose estimated by single-pool (0.96 +/- 0.33), equilibrated (0.84 +/- 0.28), and double-pool (0.84 +/- 0.30) Kt/V (compared with prescribed, each P < 0.001). There was no statistical difference between the equilibrated and double-pool Kt/V (P = NS). The solute removal index, as determined from the dialysate, corresponded to a Kt/V of 0.56 +/- 0.27 and was significantly lower than the single-pool and double-pool Kt/V (each P < 0.001). CONCLUSION: Blood-based kinetics used to estimate the dose of dialysis in ARF patients on intermittent hemodialysis provide internally consistent results. However, when compared with dialysate-side kinetics, blood-based kinetics substantially overestimated the amount of solute (urea) removal.  (+info)

Effects of carbon dioxide inhalation on hematology, coagulation, and serum clinical chemistry values in rats. (6/1427)

Blood samples from adult male and female Charles River Crl:CD (SD) BR rats were collected at weekly intervals for 4 wk to evaluate the effects of inhalation of an anesthetic dose of carbon dioxide (CO2) or of a carbon dioxide-oxygen mixture (CO2/O2) on hematology, coagulation, and serum biochemistry values. During the first 3 wk of the study, rats were assigned to 1 of 3 groups and were bled from the orbital sinus once weekly. Prior to the blood collection, rats in group 1 were exposed to room air only, rats in group 2 received CO2/O2 (approximately 66%:34% CO2:O2) by inhalation, and rats in group 3 received 100% CO2 by inhalation. In the rats exposed to CO2/O2 or CO2, leukocyte counts, lymphocyte counts, and glucose values were higher, and aspartate aminotransferase, creatine kinase, and calcium values were lower compared with those of rats exposed to room air only. Rats exposed to 100% CO2 had slightly (but statistically significant) lower mean corpuscular hemoglobin concentration when compared with rats exposed only to room air. During week 4, all rats were reassigned to 1 of 2 groups and were bled terminally via closed cardiac puncture following exposure to either CO2/O2 or CO2. Increased lymphocyte counts (males only) and glucose and chloride concentrations were noted for rats exposed to CO2/O2 compared with those exposed to CO2. These alterations reiterate the importance of comparing clinical pathology values to those of concurrent control groups that have experienced blood collection under identical conditions in order to avoid potential errors in the interpretation of data.  (+info)

Nordihydroguairetic acid is a potent inhibitor of ferric-nitrilotriacetate-mediated hepatic and renal toxicity, and renal tumour promotion, in mice. (7/1427)

Ferric-nitrilotriacetate (Fe-NTA) is a known renal carcinogen. In the present study, we report the effect of a potent lignin-derived herbal antioxidant, nordihydroguairetic acid (NDGA), against Fe-NTA-mediated tissue toxicity. Fe-NTA (alone) treatment of mice enhances ornithine decarboxylase activity to 259% in liver and 341% in kidney and increases [3H]thymidine incorporation in DNA to 250% in liver and 324% in kidney compared with the corresponding saline-treated controls. The enhanced ornithine decarboxylase activity and DNA synthesis showed a reduction to 138 and 123%, respectively, in liver at a higher dose of 2 mg NDGA/day/animal whereas in kidney the reduction was to 118 and 102%, respectively, compared with the corresponding saline-treated controls. In the Fe-NTA (alone)-treated group, a 12% renal tumour incidence was recorded whereas, in N-diethylnitrosamine (DEN)-initiated and Fe-NTA-promoted animals, the percentage tumour incidence was increased to 68% as compared with untreated controls. No tumour incidence was recorded in the DEN-initiated, non-promoted group. The administration of NDGA, afforded >80% protection against DEN- and Fe-NTA-mediated renal tissue injury in vivo. Fe-NTA treatment also enhanced hepatic and renal microsomal lipid peroxidation to 170 and 205% of saline-treated controls, respectively, and hydrogen peroxide generation by >2.5-fold in both tissues accompanied by a 51 and 21% decrease in the level of glutathione and 35-48 and 35-50% decrease in the activities of glutathione-metabolizing and antioxidant enzymes in liver and kidney, respectively. These changes were reversed significantly in animals receiving a pre-treatment of NDGA. Our data show that NDGA can abrogate the toxic and tumour-promoting effects of Fe-NTA in liver and kidney of mice and can serve as a potent chemopreventive agent to suppress oxidant-induced tissue injury and tumorigenesis.  (+info)

Protein metabolism in insulin-treated gestational diabetes. (8/1427)

OBJECTIVE: To test the hypothesis that protein metabolism is not totally normalized in insulin treated gestational diabetes mellitus (GDM) patients compared with normal, pregnant control subjects. RESEARCH DESIGN AND METHODS: Protein metabolism in eight Hispanic women with insulin-treated GDM and eight healthy Hispanic control women was studied in late gestation and at 6 weeks postpartum. Nitrogen flux was assessed from the disposal rate of [15N]-labeled urea over 12 h after a dose of [15N]-labeled leucine. Plasma amino acid concentrations were determined in fasting and 2-h postprandial samples using an amino acid analyzer. RESULTS: Protein turnover was normalized in insulin-treated GDM; however, fasting and postprandial plasma amino acids were elevated antepartum and postpartum. Nitrogen flux was significantly lower during pregnancy (P = 0.04-0.001) and did not differ between groups. Fasting and postprandial plasma amino acids were elevated in GDM antepartum and postpartum, despite satisfactory glycemic control. Fasting levels of taurine, hydroxyproline, glutamic acid, glutamine, cystine, tyrosine, phenylalanine, tryptophan, and histidine were higher in GDM antepartum and postpartum (P < 0.05). Postprandial concentrations of taurine, hydroxyproline, valine, cystine, isoleucine, leucine, tyrosine, phenylalanine, tryptophan, ornithine, lysine, histidine, and arginine were higher in GDM antepartum and postpartum (P < 0.05). With few exceptions, plasma amino acid concentrations were lower antepartum than postpartum (P < 0.05). CONCLUSIONS: Protein turnover was normalized in insulin-treated women with GDM; however, fasting and postprandial plasma concentrations of amino acids were elevated in the antepartum and postpartum periods, despite satisfactory maternal glycemic control.  (+info)

Feasibility of Reagent Test Strips to Estimate Blood Urea Nitrogen Concentrations in Egyptian Fruit Bats (Rousettus aegyptiacus ...
Two experiments were conducted to study the relationship of blood plasma urea nitrogen (PUN) concentrations with NH3, urea nitrogen, K, Mg, P, Ca, and Na concentrations in fluid of preovulatory follicles (experiment 1) and the relationships of PUN concentration and stage of estrus cycle with ammonia and urea nitrogen concentrations in uterine fluids (experiment 2) in early lactation dairy cows. Mean PUN levels were used to distribute cows into two groups: cows with PUN ≥ 20 mg/dl (HPUN), and cows with PUN | 20 mg/dl (LPUN). In experiment 1, blood and follicular fluids from preovulatory follicles of 38 early lactation dairy cows were collected on the day of estrus (day 0) 4 h after feed was offered. Follicular fluid NH3 was higher (P | 0.01) in HPUN cows (339.0 μmol/L ± 72.2) compared to LPUN cows (93.9 μmol/L ± 13.1). Follicular fluid urea N was higher (P | 0.001) in HPUN cows (22.4 mg/dl ± 0.4) compared to LPUN cows (17.0 mg/dl ± 0.3). PUN and follicular fluid urea N were correlated (r2 = 0.86)

The relationship of natriuretic effect and furosemide excretion was studied in normal and azotemic dogs. Graded azotemia was produced in dogs by bilateral uretero-venous shunts of varying duration. The shunts were subsequently opened and urine and blood samples were taken to measure inulin, furosemide and sodium concentrations. Renal blood flow was measured by an electromagnetic flow probe. Two groups of dogs, control and experimental, were studied. The experimental group received a loading dose followed by a constant infusion of furosemide. This dose produced a natriuresis in nonazotemic normal dogs. The magnitude of this natriuresis correlated with furosemide excretion rate (P less than .005) and not with the plasma concentration of the drug. Furosemide clearance and extraction were inversely correlated with blood urea nitrogen. In the furosemide-treated group the augmentation of sodium excretion was not impaired except at blood urea nitrogen concentrations of greater than 200 mg/dl (two ...
Fifty-five multiparous Holstein dairy cows were used to evaluate the singular and combined effects of somatotropin and monensin treatments during the late dry period on postpartum metabolism and production. Treatments were 1) control (C); 2) injection of exogenous bovine somatotropin (bST); 3) TMR top dressed with 300 mg of monensin/day (M); and 4) monensin and somatotropin in combination (bST+M) during the last 28 days before expected parturition. A 500-mg subcutaneous injection of sustained release somatotropin was administered adjacent to the tail head at d -28 and -14 relative to expected calving. Diet and management were the same for all cows after parturition. Production and intake were measured daily until 63 d in milk. Milk composition, blood metabolites, and body weight and condition score were measured weekly. Prepartum glucose, nonesterified fatty acid, and blood urea nitrogen concentrations were not different among treatments. Cows on the M treatment tended to have greater dry matter intake

A key advantage of using laboratory tests to determine prognosis is the potential to monitor a patients initial response to treatment. For patients with acute pancreatitis, initial treatment primarily consists of fluid resuscitation. Several routine laboratory tests have been proposed as possible predictors of outcome: serum hematocrit, serum creatinine and blood urea nitrogen levels. Results of several small single-centre studies in the late 1990s and early 2000s suggested that an elevated hematocrit or hemoconcentration at admission was a predictor of pancreatic necrosis.17,18 Unfortunately, the accuracy of hematocrit as a prognostic indicator of necrosis was not confirmed in several subsequent external validation studies.19-21 More recently, attention has focused on early changes in serum creatinine levels.22. Recent data suggest that serial measurement of blood urea nitrogen levels is the most useful routine laboratory test for determining risk of death. In a large retrospective cohort ...

Urea is hydrolyzed by urease to produce ammonia and carbon dioxide. The liberated ammonia reacts with α-ketoglutarate in the presence of NADH to yield glutamate. An equimolar quantity of NADH undergoes oxidation during the reaction resulting in a decrease in absorbance that is directly proportional to the urea nitrogen concentration in the sample.. ...
IRIS is interested in advancing methods for standardization of methods for the estimation of GFR. In human and veterinary medicine, estimation of GFR is generally considered the most useful measure for assessment of renal function. Historically, GFR has usually been crudely estimated in people and animals by measurement of blood creatinine or urea nitrogen concentrations. Urinary clearance of inulin is the gold standard method for measuring GFR. Recently, validation of simpler methods, without urine sampling (referred to as plasma clearance methods) have been evaluated by a number of individuals, including members of the IRIS Board. Compared to use of blood creatinine or urea nitrogen determinations, the GFR can more accurately be estimated by measurement of plasma clearance of a filtration marker, using a compound that is freely filtered in the glomeruli, without significant tubular reabsorption or secretion.. The IRIS Board recognizes that estimation of GFR can be of great value for ...

Analgesic-antipyretic agents and nonsteroidal anti-inflammatory drugs are the most commonly used medications worldwide for the treatment of pain and fever in children. Acute renal failure is commonly seen in adults after treatment with analgesic agents. This complication has rarely been reported in children. Here, we describe 2 patients admitted to our hospital with acute nonoliguric renal failure temporally associated with ingestion of analgesic-antipyretic drugs at therapeutic doses, The first case was a 16-year-old adolescent boy, who had taken acetaminophen (APAP) and me fenamic acid for the indication of upper respiratory tract infection with daily doses of 1500 and 500 mg, respectively. His serum urea nitrogen and creatinine values were 16 and 1.6 mg/dL. The second case was a 12-year-old boy, who had taken APAP with a daily (lose of 500 mg for abdominal pain. His serum urea nitrogen and creatinine values were 21 and 2.29 mg/dL. Both of them recovered with appropriate hydration within a ...
The standard indicators of renal function are serum levels of urea nitrogen and creatinine; their ratio is normally about 10:1. This ratio may increase when renal perfusion or urine flow is decreased, as in urinary tract obstruction or dehydration. Because serum urea nitrogen levels are more affected by these and other factors (eg, nitrogen intake, catabolism, use of corticosteroids) than are creatinine levels, the most reliable single indicator of glomerular function is the serum level of creatinine. For example, an increase in serum creatinine from 0.5 to 1.0 mg/dL represents a 50% decrease in GFR (glomerular filtration rate). Norms for serum creatinine relate to muscle mass. Therefore, only larger adolescents should have levels exceeding 1 mg/dL. Serum cystatin C has been proposed to be a more reliable indicator of glomerular function but may be less widely available, with variable reference ranges in the pediatric population and invalid values observed in the setting of corticosteroid ...
Results:. The serum potassium concentration in the treatment group (mean ±SD) was 3.89 ± 0.46 mmol/L (95% CI, 3.79 to 3.99 mmol/L), and it increased by 1.21 mmol/L (CI, 1.09 to 1.32 mmol/L) 4.6 ± 2.2 days after trimethoprim-sulfamethoxazole therapy was initiated. Blood urea nitrogen levels increased from 7.92 ± 5.7 mmol/L (CI, 6.67 to 9.16 mmol/L) to 9.2 ± 5.8 mmol/L (CI, 7.9 to 10.5 mmol/L), and serum creatinine levels increased from 102.5 ± 49.5 µmol/L (CI, 91.4 to 113.6 µmol/L) to 126.1 ± 70.7 µmol/L (CI, 110.3 to 141.9 µmol/L). Patients with a serum creatinine level of 106 µmol/L (1.2 mg/dL) or more developed a higher peak potassium concentration (5.37 ± 0.59 mmol/L [CI, 5.15 to 5.59 mmol/L]) than patients with a serum creatinine level of less than 106 µmol/L (4.95 ± 0.48 mmol/L [CI, 4.80 to 5.08 mmol/L]). Patients with diabetes had a slightly higher peak potassium concentration (5.14 ± 0.45 mmol/L [CI, 4.93 to 5.35 mmol/L]) than did patients without diabetes (5.08 ± 0.59 ...

Deoxyribonuclease-1-like 2 is an enzyme that in humans is encoded by the DNASE1L2 gene. Model organisms have been used in the study of DNASE1L2 function. A conditional knockout mouse line, called Dnase1l2tm1(KOMP)Wtsi was generated as part of the International Knockout Mouse Consortium program - a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty three tests were carried out on mutant mice and eight significant abnormalities were observed. Homozygous mutant animals had a decreased body weight, grip strength and bone mineral content; a kinked tail, abnormal indirect calorimetry and femur/tibia morphology. Females also had an increased blood urea nitrogen level while males had a decreased leukocyte cell number.

Diagnosis of AKI is based on patient history, physical examination, bloodwork evaluation, urine testing (urinalysis and urine culture) and abdominal ultrasound. During the diagnostic workup, it is critical for your veterinarian to determine if an animal is affected with AKI, longer standing chronic kidney disease or a combination of both, as prognoses can be very different (this can sometimes be difficult to distinguish). If AKI is diagnosed or suspected, further specific testing such as blood pressure measurement and testing for inflammatory or infectious diseases may be performed.. As above, patients with AKI will usually have a sudden onset of abnormal clinical signs and no history of significant weight loss (unless there are other underlying disease processes). On physical examination, patients may exhibit pain in the area of their kidneys.. In a patient with AKI, bloodwork evaluation will show elevated blood urea nitrogen (BUN) and creatinine values, which are the most commonly used markers ...

Blood urea nitrogen (BUN) and creatinine are lab values that indicate possible changes in kidney function. GFR measures kidney function.
The most reliable way to measure kidney disease is by testing for glomerular filtration rate-the speed at which blood enters, is cleaned, and then leaves the kidney. A rate of less than 60 milliliters every minute over three months indicates chronic kidney disease.. A blood test for levels of creatine is a part of calculating the filtration rate. Creatinine is an acid that promotes muscle growth. When the kidney is not working effectively, the amount of creatinine in the blood increases. Other commonly ordered tests include calcium, phosphorus, parathyroid hormone, potassium, blood urea nitrogen (BUN), and bicarbonate.. A doctor also will test for protein in the urine, particularly for a protein called albumin, and ask questions about personal and health histories to determine if there are any other causes for the results of the blood and urine tests.. Your doctor may order an ultrasound ...
