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)

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 ...

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 ...

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 ...

Sepsis-associated acute kidney injury (SA-AKI) is an independent risk factor for death in patients with sepsis, but treatment for it is limited. To improve the diagnosis and treatment of SA-AKI, we must first understand its pathogenesis. Recently, interleukin (IL)-17A has been shown to be associated with the pathogenesis of acute kidney injury and sepsis, but its role in SA-AKI remains unclear. SA-AKI was induced in male C57BL/6 and IL-17A−/− mice using cecal ligation and puncture (CLP) operations for 24 h. At 7 days, only seven mice survived in the wild-type septic group, but nine survived in the IL-17A−/− septic group, corresponding to survival rates of 25 % and 45 %, respectively. At 24 h after CLP operations, both wild-type and IL-17A−/− septic mice developed kidney injury. The IL-17A−/− septic mice exhibited decreased serum creatinine and blood urea nitrogen levels and an improved acute tubular necrosis score. The IL-17A−/− septic mice exhibited decreased IL-6, interferon-γ,
Nine multiparous lactating cows averaging 171 days in milk were divided according to days in milk and milk production into three 3×3 Latin squares with three 3-week periods to investigate the effect of rumen degradable protein on milk urea nitrogen. Diets were formulated to provide 3 concentrations of dietary rumen degradable protein (9.8, 10.8, and 11.8% of dry matter), while rumen undegradable protein (4.6% of DM) remained constant. Each period was 3 weeks in length, with 2 weeks used for adjustment and one week used for sampling. Rumen degradable protein levels had a low effect on milk yield (P|0.05), but a significant effect on protein percentage and milk urea nitrogen content. There was linear increase in the milk urea nitrogen content of cows fed diets one to three (P|0.01). Milk urea nitrogen is a simple and noninvasive measurement that can be used to monitor nitrogen efficiency in dairy cows. These results indicated that milk urea nitrogen might be used as a parameter to monitor the change in

Acute kidney injury (AKI), previously called acute renal failure (ARF), is a rapid loss of kidney function. Its causes are numerous and include low blood volume from any cause, exposure to substances harmful to the kidney, and obstruction of the urinary tract. AKI is diagnosed on the basis of characteristic laboratory findings, such as elevated blood urea nitrogen and creatinine, or inability of the kidneys to produce sufficient amounts of urine. Source: Wikipedia. ...
Acute kidney injury (AKI) is an abrupt and usually reversible decline in the glomerular filtration rate (GFR). This results in an elevation of serum blood urea nitrogen (BUN), creatinine, and other metabolic waste products that are normally excreted
CASE HISTORY: A 6-year-old, neutered, female Angora cat presented with a history of lethargy and anorexia for 2 months and a clinically palpable and gradually enlarging, solid mass in the abdominal cavity extending from the last costal arch to the pelvic cavity.CLINICAL FINDINGS: Examination of the cat revealed jaundice, dehydration and hypothermia. Haematological manifestations included lymphopenia and substantial decrease in haematocrit value. Biochemical analysis of the blood revealed hypoglycaemia, three-fold elevated blood urea nitrogen values, increased level of serum aspartate aminotransferase and increased total bilirubin while the creatinine level was normal. Ultrasonographic examination of the abdomen showed a disrupted and large hypoechoic area around the left kidney. The cat was anaesthetised and the left kidney was removed, but the cat died following surgery.PATHOLOGICAL FINDINGS: On post-mortem examination, the left kidney was markedly enlarged and both the cortical and medullary ...
Angiotensin-converting enzyme inhibitors (ACEIs) were accepted as a potential cause of inadequate epoetin response in chronic kidney disease (CKD) patients. We aimed to determine the effects of valsartan, an angiotensin receptor blocker (ARB), on serum ertyhropoietin levels and on certain biochemical and haematological parameters in hypertensive CKD patients. Twenty-two stage III-IV CKD patients (mean age; 56.8 +/- 8.9 years, 12 male 10 female) were included in the study. Before initiating the treatment, current anti-hypertensive treatments (if any) were discontinued, and blood samples were collected after a washout period of 3 weeks. Valsartan 80 mg/day was started, and additional anti-hypertensive agents were given according to study protocol if needed. One way Anova and paired t-tests were used for statistical comparisons. Serum blood urea nitrogen (BUN), creatinine, uric acid, potassium, haemoglobin and erythropoietin values were measured, and glomerular filtration rates were calculated ...
Background: Advanced-stage chronic kidney disease (CKD) may contribute to left ventricular hypertrophy, fibrosis, and diastolic dysfunction, which increase risk of cardiovascular mortality. However, whether cardiac remodeling occurs in early stages of CKD is unclear. In rats subjected to single nephrectomy, we examined cardiac structural changes and their underlying mechanisms in early stages of CKD.. Methods and Results: Adult male Sprague-Dawley rats underwent single nephrectomy (SNx; n=8) or sham (n=8) operations. Eight weeks later, the SNx group had a higher serum blood urea nitrogen (18.58±0.67 vs 13.40±0.78 mg/dL; P,.02) level, creatinine (0.45±0.02 vs 0.36±0.02 mg/dL; P,.02) level, systemic pulse pressure (48±5 vs 33±1 mmHg; P,.02), and echocardiographic transmitral deceleration time (65.3±2.6 vs 51.2±2.8 ms; P,.02) than the sham group. Doppler imaging and pressure-volume relationship (PVR) analysis performed in both groups revealed impaired diastolic function in SNx rats, which ...
The terms uremia and azotemia are applied to acute or chronic conditions in which the blood concentration of nitrogenous end products rises. The terms are otherwise poorly defined. Nitrogen retention usually occurs when the renal function is less than 30% of normal. Recently, progressive renal dysfunction has been graded as [1] diminished renal reserve, [2] renal insufficiency, [3] renal failure, and [4] uremia (Strauss and Welt (1) 1963), but each grade overlaps others.. Although urea is present in greatest amount, errors can occur when increased urea concentration is accepted as synonymous with the degree of renal dysfunction. Myers, Fine, and ...
How Is the BUN Level Measured?. To test your pets BUN level, your veterinary team must obtain a small blood sample. This procedure is usually very quick; it may take only a few seconds if the patient is well behaved. For patients that are very frightened or not well behaved, your veterinary team may want to use a muzzle, towel, or other gentle restraint device. In some cases, such as in patients with very thick fur, it may be necessary to shave the hair from the area where blood will be drawn. The hair will grow back, and this is often a good way to find the vein quickly.. Some veterinary offices have in-house blood analysis equipment, so they can perform the BUN level test in the office and have results the same day. Other offices send blood samples to an outside laboratory for the test to be performed. If an outside laboratory is used, results are generally available within 1 to 2 days. Be sure to tell your veterinarian about any medications or supplements your pet may be receiving, as some ...
This test measures the amount of urea nitrogen in your urine.. Urea nitrogen is a waste product made when your liver breaks down protein. Its carried in your blood, filtered out by your kidneys, and removed from your body in your urine. If your liver isnt healthy, it may not break down proteins the way it should. And if your kidneys arent healthy, they may not properly filter urea. Either of these problems can lead to changes in the amount of urea nitrogen in your body. If you dont have enough fluid in your body (dehydration), you may have extra urea in your blood because you arent passing much urine. ...
TY - JOUR. T1 - Development of fasting hyperglycemia in uremic rats. AU - Reaven, Gerald M.. AU - Reaven, Peter D.. PY - 1977/11. Y1 - 1977/11. N2 - Rats which had been fasted for the previous 24 hr were subjected to either sham surgery, bilateral nephrectomy, or bilateral ureterotomy. The fast was continued for another 24 hr before the animals were decapitated and blood was obtained for determination of serum glucose, insulin, and urea nitrogen levels. A moderate but statistically significant (p , 0.02) fall in serum glucose levels occurred in rats made uremic by bilateral nephrectomy. In contrast, rats made equally uremic by bilateral ureterotomy developed a significant (p , 0.001) elevation of both serum glucose and insulin levels. The combination of hyperglycemia and hyperinsulinemia suggested that insulin resistance had developed in these rats, and this was confirmed by demonstrating that the hypoglycemic effect of exogenously administered insulin was attenuated in rats following bilateral ...
We analyzed the effects of acute ischemia-reperfusion (KIR) injury on the status of kidney function and architecture in dipeptidyl peptidase4-difficient (DPP4(D)) rats and the effect of remote small bowel ischemia-reperfusion (BIR) preconditioning. DPP4-deficient (DPP4(D)) and normal Fischer344 (F344) rats were divided into 6 groups: (1) sham-F344, (2) sham-DPP4(D), (3) KIR-F344 (4) KIR-DPP4(D), (5) DPP4(D)-KIR-extendin-9-39 and (6) BIR-KIR-F344. Blood creatinine and urea nitrogen levels and the urinary protein-to-creatinine ratio was higher in KIR-F344 rats than BIR-KIR-F344 or KIR-DPP4(D) rats 72 h after acute KIR. Conversely, the circulating glucagon-like peptide 1 (GLP-1) levels were higher in BIR-KIR-F344 and KIR-DPP4(D) than KIR-F344 rats after acute KIR. KIR-F344 rats showed greater inflammation, oxidative stress, apoptosis, DNA damage and kidney injury than other rat groups. Damage to the kidney architecture in KIR-F344 rats was greater than in BIR-KIR-F344 or KIR-DPP4(D) rats. ...
Cisplatin (CP) is commonly used in the treatment of different types of cancer but nephrotoxicity has been a major limiting factor. Therefore, the present study aimed to study the possible protective effect of rutin against nephrotoxicity induced by cisplatin in rats. Forty male Wistar albino rats were randomly divided into 4 groups. Rats of group 1 control group intraperitoneal (i.p.) received 2.5 ml/kg, group 2 CP group received single dose 5 mg/kg cisplatin i.p. group 3 rutin group orally received 30 mg/kg rutin group 4 (CP plus rutin) received CP and rutin as in group 2 and 3. Kidneys were harvested for histopathology and for the study the gene expression of c-Jun N-terminal kinases (JNK), Mitogen-activated protein kinase 4 (MKK4), MKK7, P38 mitogen-activated protein kinases (P38), tumor necrosis factors alpha (TNF-α), TNF Receptor-Associated Factor 2 (TRAF2), and interleukin-1 alpha (IL-1-α). The cisplatin single dose administration to rats induced nephrotoxicity associated with a significant
Reports demonstrate that excess dietary protein significantly alters the ionic composition of uterine fluid during the luteal phase ultimately decreasing fertility. Since the early bovine embryo cannot adapt to changes in the uterine environment, changes in the concentrations of ions (pH) in the uterus can be unfavorable to embryo development and survival therefore having negative effects on fertility. In this study, heifers fed a high protein diet had elevated systemic concentrations of plasma urea nitrogen (PUN) compared to heifers fed a control diet. However, there was no deleterious effect on uterine pH or reproductive success. In summary, excess protein in a diet did increase PUNs to a concentration that has previously been reported to be detrimental to pregnancy success; however, there was no negative effect on uterine pH or pregnancy success.
A study was conducted to assess the effect of mannan-oligosaccharides (MOS) and fructo-oligosaccharides (FOS) either alone or in combination on serum biochemical profile and immunocompetence in meat-type quails from day old to 5 weeks of age. Nine experimental diets were prepared incorporating three levels (0, 1.0 and 2.0 g/kg diet) each of MOS and FOS in a factorial manner. Four hundred and five day-old quail chicks were distributed into 9 experimental groups of 45 chicks in each, with three replicates in each treatment. At the end of five weeks, blood was collected from six birds of each treatment and the serum was analyzed for total protein, total cholesterol and triglycerides. The results revealed that the quails from all treatment groups receiving MOS and /or FOS recorded lower serum cholesterol and triglycerides with higher total protein. However, differences between different treatments were statistically non-significant. The humoral immune response, as measured by haemagglutination ...
TY - JOUR. T1 - Protective Role of Natural Products in Cisplatin-Induced Nephrotoxicity. AU - Ridzuan, Nurul Raudzah Adib. AU - Rashid, Norhashima Abd. AU - Othman, Faizah. AU - Budin, Siti Balkis. AU - Pa Pa Hlaing @ Farida Hussan, Khin. AU - Teoh, Seong Lin. PY - 2019/1/1. Y1 - 2019/1/1. N2 - Cisplatin is a widely used antineoplastic agent for the treatment of metastatic tumors, advanced bladder cancer and many other solid tumors. However, at higher doses, toxicities such as nephrotoxicity may appear. Cisplatin leads to DNA damage and subsequently renal cell death. Besides that, oxidative stress is also implicated as one of the main causes of nephrotoxicity. Several studies showed that numerous natural products: ginseng, curcumin, licorice, honey and pomegranate were able to reduce the oxidative stress by restoring the levels of antioxidant enzymes and also at the same time act as an anti-inflammatory agent.

Creatinine and BUN both are the common indicator to show the kidney function. For normal people, the healthy level of creatinine should be controlled in 0.5-1.2mg/dL and the BUN level should keep in 9-20mg/dL. FSGS patients with creatinine
In China, the lab has a renal function test, which is actually a blood test about three index including serum creatinine, BUN( blood urea nitrogen) and uric acid, all of which is used to test whether the renal function is well for all of them are toxins which should have been discharged out. Among them, serum creatinine is the most scientific index which can show how renal functions. After all, kidney is an organ which is used to secrete the waster product. So both in Chinese labs or foreign labs, doctors value serum creatinine as the most valuable reference of renal function. Consequently, patients with kidney disease will also concentrate on the value of their serum creatinine. They also want to know about how to reduce creatinine ...
The lab will test the amount of creatinine in your urine, and then compare that to the amount of creatinine in your blood. Answered by Dr. Alok Agrawal: Depends: Depends on the cause. I am currently 41 (M) and have an eGFR of 32. Dehydration refers to inadequate water and electrolyte balance in your cells, which can cause high BUN levels. Your healthy creatinine level depends on how much muscle you have in your body and the good number may be different for people who have lower or higher muscle mass than average people. Serum creatinine is part of a routine lab report; creatinine clearance is not. For kidney disease patients, some of them may be troubled by such a question:how to keep my creatinine levels down? If you eager to know more about this, please read on. Treatments for Low Creatinine Levels. If you have high blood pressure, you may get a microalbumin creatinine ratio at regular intervals, as recommended by your health care provider. Results can vary depending on your age, gender, ...
Backgrounds: Cisplatin (CDDP) is a choice of anti-cancer drug for cancer chemotherapy with serious side effects such as nephrotoxicity. It seems that age is an important factor influencing the side effects of CDDP. This study was designed to determine the role of age and gender simultaneously in CDDP induced renal toxicity. Methods: 40 Wistar male and female rats were assigned as 6 groups in 3 different age categories (10, 16, and 20 weeks old). The single dose of CDDP (7.5 mg/kg, ip) was administrated, and a week later measurements were performed. Results: Body weight changes in male (not in female) animals aged 16 and 20 weeks were more than 10 weeks old animals (P|0.05). In male rats, the serum levels of creatinine (Cr) and blood urea nitrogen (BUN), and Cr-clearance in aged 10 weeks, normalized kidney weight (KW) in aged 20 weeks, and serum nitrite, aspartate aminotransferase (AST) and malondialdehyde (MDA) levels and kidney tissue damage score (KTDS) in rats aged 16 weeks were significantly
Alkaline Phosphatase (ALKP) - ALKP is an enzyme present in multiple tissues, including liver and bone. Elevated levels can indicate liver disease, Cushings syndrome or steroid therapy.. Total Protein (TP) - The level of TP can indicate a variety of conditions, including dehydration, inflammation and diseases of the liver, kidney or intestine.. Alanine Aminotransferase (ALT) - ALT is an enzyme that becomes elevated with liver cell injury.. Blood Urea Nitrogen (BUN) - BUN is produced by the liver and excreted by the kidneys. Abnormally high levels can indicate kidney disease or dehydration, and low levels can be associated with liver disease.. Creatinine (CREA) - Creatinine is a byproduct of muscle metabolism and is excreted by the kidneys. Elevated levels can indicate kidney disease, urinary tract obstruction or dehydration.. Phosphorus (PHOS) - Elevated phosphorus can be an indicator of kidney disease.. Blood Glucose (GLU) - High levels can indicate diabetes. In cats, high levels can also ...

Materials and method: The rats were divided into four groups, with 10 animals per group: control (C), group, low-treated (LT), group, mediumtreated (MT), group, and high-treated (HT), group. The C group received distilled water, while LT, MT and HT groups were given various doses of PGP (100, 200, 400 mg/kg· d). After 30 days, forced swimming test was carried out in an acrylic plastic pool, then the exhaustive swimming time of rats and some biochemical parameters related to fatigue were measured. The data obtained showed that PGP could extend the exhaustive swimming time of the rats, as well as decrease the blood lactic acid (BLA), and blood urea nitrogen (BUN), concentrations, and increase the hemoglobin, liver glycogen and muscle glycogen concentrations ...

Chronic kidney disease is one of the most common disorders in dogs and cats. The plasma urea nitrogen (P-UN) and creatinine (P-Cre) concentrations are not sufficiently sensitive for early diagnosis of renal dysfunction. Although urine and plasma clearance methods allow earlier detection of reductions in the GFR, it is difficult to estimate a mildly reduced GFR from the values obtained by these methods, as they are also affected by physiological factors, such as body weight (BW) and age. The present study is a retrospective survey designed to assess the factors that affect markers of kidney function and to revaluate the clinical utility of the markers, including P-UN, P-Cre and GFR determined by plasma iohexol clearance (PCio) in dogs and cats. The P-UN, P-Cre and PCio values in dogs and the P-Cre and PCio values in cats were significantly correlated with BW (P,0.001). PCio in smaller dogs (≤ 15.0 kg) was significantly and inversely correlated with age. In smaller dogs, increase of P-UN alone ...

Percent organic nitrogen differed significantly among grasses and storage organs but not to the same extent as with TNC. We of nonstructural polysaccharide accumulated (Smith, 1968; suggest that TNC concentrations of storage organs must be determined for each grass before sampling for TNC levels, in Grasses of subtropical order to locate storage organs with greatest TNC concentration.
Cytokinesis plays an important role in the etiology of multiple myeloma. The transforming growth factor (TGF) beta 1 levels in 82 sera from 60 patients with multiple myeloma were analyzed by ELISA. Fourty one sample were obtained before treatment from newly diagnosed patients, 22 after treatment from the same patients and 19 from relapsed/refractory patients. Serum median TGF level of newly diagnosed patients was 769.5 ng/mL (126-1853), and the relapsed/refractory patients had similar levels. TGF levels after chemotherapy were not different between patients that reached plateau phase and those who remained refractory. We found a negative correlation between TGF and C-reactive protein and blood urea nitrogen and a positive correlation between TGF and hemoglobin level in newly diagnosed patients. After treatment, it was determined that TGF levels at diagnosis were higher in patients who reached plateau phase than in the refractory patients. Elevated serum TGF concentration at diagnosis in multiple ...

His phosphorous levels are now normal which is surprising being that he is still not on a prescription diet. I was more concerned with him eating and hopefully gaining a little weight. He is a lot less fussy lately so I am going to try the kidney diet again.. His urea nitrogen is still high, but much better than before. It went from 117 down to 90. His creatinine also went down from 7 to a 4.5 ( still high, but better). Those were all the positives.. There is one number that got worst, the hematocrit. It went from a 35 to a 26 which is odd. He was in the normal range and now he is not. The vet wants this retested again next week because there is a shot that can help that if it stays low. She also said to continue with the fluids every other day for now.. Thank you all for your purrs and prayers. They are greatly appreciated. I will keep you updated on his test next week..
