Significant Differences In Blood Urea Nitrogen Research Articles

THE EFFECT OF GIVING NATURAL GUARD ESSENTIAL OIL IN DRINKING WATER ON BLOOD UREA NITROGEN LEVELS, CREATININE, AND AMINOTRANSFERASE IN BROILERS

To increase growth and feed efficiency, we can use feed additives through feed or drinking water, one of which is the use of essential oils. NATURALGUARD is a mixture of natural oils, namely pine oil (Pinus sp.), lavender (Lavandula sp.), and eucalyptus oil (Eucalyptus sp.) which contains active compounds as immunomodulators, antibacterials, antioxidants, anti-inflammatory, antifungal and antiviral. This study aims to determine the level of Blood Urea Nitrogen (BUN), Creatinine, Aspartate Aminotransferase (AST), and Alanine Aminotransferase (ALT) in broilers after being given NATURALGUARD via drinking water. This study used a completely randomized design with a total sample of 24 broiler CP-707 strain, with four treatments and six replications. The treatment applied was P0 as a control without giving NATURALGUARD, P1 P2, and P3 were given NATURALGUARD at doses of 1, 2, and 4 g/L respectively, adlibitum for 30 days. At the end of the study, 3 mL of blood sample was taken via the pectoral vein aseptically, and then a blood serum examination was carried out. The research results showed that the highest mean BUN level was at P0 (8.9 mg/dL) and the lowest was at P1 (5.2 mg/dL), the highest creatinine was at P3 (1.08 mg/dL) and the lowest was at P0 and P1 (1, 0 mg/dL), AST was highest at P0 (273 µ/L) and lowest at P2 (220 µ/L), and ALT was highest at P0 (7.5 µ/L) and lowest at P3 (5.48 µ/ L). Statistical results showed no significant differences in BUN, creatinine, AST, and ALT levels in all treatment groups. It was concluded that NATURALGUARD as feed additive at doses of 1, 2, and 4 g/L via drinking water is safe to be used in broilers.

Early Diagnostic Value of KIM-1, NGAL, and NLR in Acute Kidney Injury Caused by Diquat Poisoning

Background. The kidney is the main excretory organ after diquat absorption. Acute kidney injury (AKI) is a common complication in diquat poisoning patients. Objectives. To identify the value of combined detection of neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and neutrophil-lymphocyte ratio (NLR) in the early diagnosis of diquat-induced AKI. Materials and Methods. The retrospective cohort study included 42 diquat poisoning patients. Results. Forty-two patients with diquat poisoning were included, of which 20 had fulminant poisoning (47.6%). At admission (0 h), levels of KIM-1, NGAL, NLR, and acute physiology and chronic health evaluation (APACHE) II scores in the fulminant poisoning group were higher than that of the moderate to severe poisoning group ( P < 0.05), and they were all higher than in the control group ( P < 0.05), while blood urea nitrogen (BUN) and uric acid (UA) levels did not significantly differ across the three groups ( P > 0.05). At 12 h and 24 h, the levels of KIM-1, NGAL, NLR, UA, BUN, and APACHE II scores of patients in the fulminant poisoning group were higher than those in the moderate to severe poisoning group ( P < 0.05), 12 h were higher than 0 h, and 24 h were higher than 12 h ( P < 0.05). Among 42 patients with diquat poisoning, 28 had AKI (66.7%). At 0 h, the AKI group had higher levels of KIM-1, NGAL, NLR, and APACHE II scores than in the non-AKI (NAKI) group ( P < 0.05), while there was no significant difference in BUN and UA levels between the two groups ( P > 0.05). At 12 h and 24 h, the levels of KIM-1, NGAL, NLR, UA, BUN, and APACHE II scores in the AKI group were higher than those in the NAKI group ( P < 0.05), 12 h were higher than 0 h, and 24 h were higher than 12 h ( P < 0.05). KIM-1, NGAL, and NLR are independent risk markers for AKI in diquat poisoning patients. At admission (0 h), the combined application of KIM-1, NGAL, and NLR’s sensitivity, specificity, and area under the curve (AUC) for predicting AKI in diquat poisoning patients was 0.893, 0.859, and 0.903, respectively. Conclusions. KIM-1, NGAL, and NLR can be employed as early diagnostic indicators for the clinical prediction of AKI in diquat poisoning patients. Our findings may help clinicians reduce the occurrence of AKI.

Radioprotective Effects of Melatonin on Gamma Radiation- Induced Tissue Damage in Rats


 
 Background & Objective: Gamma rays are widely used in medicine despite their harmful effects on health. Our study evaluated the protective effects of melatonin on kidney, heart, and liver tissues.
 
 Materials & Methods: Seventy-two adult male Wistar rats were categorized into nine groups. Groups 2 and 3 only received whole-body γ-ray irradiation (WBI) (2.0 Gy), no melatonin, interval time (IT) 8hr and 24hr. Groups 4 and 5 received WBI (8.0 Gy, no melatonin, 8hr and 24hr). Groups 6 and 7 received melatonin at 60 minutes (min) before WBI(2.0 Gy). Groups 8 and 9 received melatonin before WBI(8.0 Gy). All the rats were sacrificed 8 or 24 h after the experiments for laboratory and histopathological analysis. Serum levels of Blood Urea Nitrogen(BUN), Creatinine (Cr), Lactate dehydrogenase (LDH), Potassium (K), Gamma-glutamyl Transferase (GGT), Serum Glutamic-Oxaloacetic Transaminase(SGOT), Serum Glutamic-Pyruvic Transaminase(SGPT), Alkaline Phosphatase(ALP), c-reactive protein(CRP), Troponine(TPO) and histological features of liver, heart and kidney tissues were assessed. Statistical analysis was performed by One-Way ANOVA.
 
 Results: Our data did not indicate significant differences in BUN, Cr, K, and CRP between groups with or without melatonin treatment (P>0.05); but differences were significant for LDH, GGT, SGOT, SGPT, ALP, and TPO (P<0.05). The results showed that radiation-induced histopathological effects on the liver, heart, and kidneys were mitigated in the groups six to nine.
 
 Conclusion: The existence of significant differences in serum levels of LDH, GGT, SGOT, SGPT, ALP, and TPO in groups(6 to 9) and amelioration of the histopathological effects of irradiation on the liver, heart, and kidneys in the groups six to nine showed that the melatonin(100 mg/kg) is able to protect the body in gamma-radiation(2.0 Gy and 8.0 Gy).
 

Evaluation of N-(6-[18F]Fluoropyridin-3-yl)glycine PET renography to detect renal function progression in a rat model of diabetic nephropathy

ObjectiveGiven the limitation of biomarkers to predict the renal function progression in diabetic nephropathy, N-(6-[18F]Fluoropyridin-3-yl)glycine (6-[18F]FPyGly) was used to evaluate renal function progression in a rat model of diabetic nephropathy. MethodsTwenty male Sprague-Dawley rats were randomly divided into four groups, including the healthy control group (HC group), diabetic nephropathy group (DNM group), routine diet treated diabetic nephropathy group (RDNM group), and high fat/high sucrose -diet-fed diabetic nephropathy group (HDNM group). All renal function parameters were determined from animal PET renograms. P and Tmax represent the curve peak counts and the time to the curve peak counts of 6-[18F]FPyGly in kidneys after injection, C1/2 and the 15 min/Peak ratio represent the time from peak to 1/2 peak in the clearance phase, and the ratio of the curve counts at 15 min to the curve peak counts. ResultsP, Tmax, C1/2, and 15 min/peak ratio of each rat were significantly correlated with S-Cr, BUN. There were significant differences in Tmax, P, serum creatinine (SCr), and blood urea nitrogen (BUN) levels between HC and DNM groups. P and the 15 min/Peak ratio were significantly different among DNM, RDNM, and HDNM groups, while Tmax and C1/2 were only significantly different between DNM and RDNM or HDNM groups. There only was a significant difference in BUN between the DNM and HDNM groups. ConclusionThe renal function parameters P, Tmax, C1/2 and 15 min/peak value obtained by dynamic renal imaging based on 6-[18F]FPyGly could reflect changes of renal function in rats, which had a good correlation with SCr and BUN, and showed more efficient in the diagnosis of diabetic nephropathy and renal function classification than SCr and BUN.

Probiotics improve renal function, glucose, lipids, inflammation and oxidative stress in diabetic kidney disease: a systematic review and meta-analysis

Aims The role of probiotics in the management of diabetic kidney disease (DKD) has been shown. Several current trials are investigating the effect of probiotics, which are widely used to modulate biomarkers of renal function, glucose, lipids, inflammation and oxidative stress in patients with DKD. However, their findings are controversial. This study aimed to systematically evaluate the impact of probiotics on patients with DKD via meta-analysis. Methods PubMed, The Cochrane Library, Web of Science, Scopus, Embase, China National Knowledge Infrastructure, Chinese Wanfang Database and Chinese VIP Database were searched for relevant studies from the establishment of these databases to September 2021. The pooled results evaluated the impact of probiotics on renal function, glucose, lipids, inflammation and oxidative stress indicators in patients with DKD. Additionally, subgroup analysis was performed based on intervention duration, probiotic dose and probiotic consumption patterns, respectively. Results Ten trials that included 552 participants were identified for analysis. Compared with the controls, probiotics significantly decreased serum creatinine (Scr) [WMD = −0.17 mg/dL; 95%CI = −0.29, −0.05; p = 0.004], blood urea nitrogen (BUN) [WMD = −1.36 mg/dL; 95%CI = −2.20, −0.52; p = 0.001], cystatin C (Cys C) [WMD = −29.50 ng/mL; 95%CI = −32.82, −26.18; p < 0.00001], urinary albumin/creatinine ratio (UACR) [WMD = −16.05 mg/g; 95%CI = −27.12, −4.99; p = 0.004] and natrium (Na) [WMD = −0.94 mmol/L; 95%CI = −1.82, −0.05; p = 0.04] in patients with DKD. Enhanced glycemic control was observed in patients with DKD receiving probiotics compared with controls, as demonstrated by reduced levels of fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), homeostasis model of assessment-estimated insulin resistance (HOMA-IR), and increased quantitative insulin sensitivity check index (QUICKI). Probiotics affected lipid metabolism parameters with decreasing triglycerides (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-c) levels in patients with DKD. Probiotics could also could improve inflammation and oxidative stress by decreasing high-sensitivity C-reactive protein (hs-CRP), plasma malondialdehyde (MDA), total antioxidant capacity (TAC), glutathione (GSH) and nitric oxide (NO). Additionally, subgroup analysis showed that those who received multiple species probiotics had a statistically significant difference in BUN, FPG, HOMA-IR, high-density lipoprotein cholesterol (HDL-c), MDA, TAC, and NO. Meanwhile, Scr, LDL-c, HDL-c, MDA, and TAC were ameliorated when the intervention duration was more than eight weeks and BUN, FPG, HOMA-IR, and MDA were improved when the probiotic dose was greater than four billion CFU/day. Conclusions Our analysis revealed that probiotics could delay the progression of renal function injury, improve glucose and lipid metabolism, and reduce inflammation and oxidative stress in patients with DKD. Subgroup analysis showed that intervention duration, probiotic dose and probiotic consumption patterns had an effect of probiotics on outcomes.

The Effect of Pluchea indica (L.) Less. Tea on Blood Glucose and Lipid Profile in People with Prediabetes: A Randomized Clinical Trial.

Objective: Diabetes mellitus and dyslipidemia are currently increasing dramatically, and conventional medicine in the treatment of them has limited efficacies and serious adverse effects. Pluchea indica (L.) Less. tea (PIT) is widely consumed as a health-promoting drink in Southeast Asia. This study aimed to investigate whether P. indica tea has antidyslipidemic and antihyperglycemic effects and toxicity in humans. Design: A randomized clinical trial. Setting/Location: Nakhonratchasima, Thailand. Participants: Forty-five participants with prediabetes. Interventions: Participants were randomized to receive placebo tea, 1.5 g of PIT, and 1.5 g Camellia sinensis tea (green tea, CST) once daily for 12 weeks. Outcome Measurements: The oral glucose tolerance test (OGTT), total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood urea nitrogen (BUN), creatinine, alanine transaminase (ALT), alkaline phosphatase (ALP), and complete blood count (CBC) before and after treatment were investigated. Results: The results showed that PIT significantly ameliorated hyperglycemia and significantly lower serum TG (109.22 ± 5.21 mg/dL) and LDL-C (122.20 ± 3.67 mg/dL) than placebo (145.56 ± 8.18 and 142.07 ± 8.58 mg/dL, respectively) (p < 0.05). Moreover, PIT exhibited serum TG (109.22 ± 5.21 mg/dL) significantly lower than CST (124.38 ± 4.70 mg/dL) (p < 0.05). In addition, the serum HDL-C of PIT (57.56 ± 3.05 mg/dL) was significantly higher than the placebo (46.44 ± 2.47 mg/dL) (p < 0.05). Furthermore, the toxicity testing showed that no significant difference in BUN, creatinine, ALT, ALP, and CBC of PIT-treated group compared with the placebo (p > 0.05). Conclusions: These results suggest that PIT may ameliorate hyperglycemia and dyslipidemia in prediabetes people. It may not be toxic to the kidney, liver, and blood. So, PIT has the potential to develop to be a health-promoting tea or herbal medicine for hyperglycemia and dyslipidemia prevention.

Effect of indwelling nasointestinal tube for enteral nutrition support in patients with severe craniocerebral trauma undergoing mechanical ventilation

To evaluate the effect of indwelling nasointestinal tube for enteral nutrition (EN) support on patients with severe craniocerebral trauma undergoing mechanical ventilation (MV). A total of 100 severe craniocerebral trauma patients undergoing MV admitted to intensive care unit (ICU) of the 117th Hospital of People's Liberation Army from February 2015 to February 2017 were enrolled, and they were divided into nasogastric tube group in which the EN was fed by nasogastric tube and nasal jejunal feeding tube group (nasointestinal tube group) by random digits table, with 50 patients in each group. Blood urea nitrogen (BUN), hemoglobin (Hb), serum albumin (Alb), acute physiology and chronic health evaluation II (APACHE II) score, Glasgow coma scale (GCS) score before and 10 days after treatment, duration of MV, hospitalization time, and the incidences of ventilator-associated pneumonia (VAP) and reflux wrong aspiration of the two groups were observed and compared. There was no statistically significant difference in BUN, Hb, Alb, APACHE II score or GCS score before treatment between the two groups. Ten days after treatment, BUN and APACHE II score in the nasointestinal tube group were significantly lower than those in the nasogastric tube group [BUN (mmol/L): 6.3±1.6 vs. 8.0±2.2, APACHE II score: 17.9±3.2 vs. 20.8±6.3, both P < 0.05], Hb, Alb, GCS score were significantly higher than those in nasogastric tube group [Hb (g/L): 125.9±19.7 vs. 113.5±19.6, Alb (g/L): 35.9±6.2 vs. 31.9±6.2, GCS score: 9.7±1.9 vs. 8.2±5.7, all P < 0.05], duration of MV and hospitalization time were significantly less than those in the nasogastric tube group [duration of MV (days): 14.7±3.4 vs. 17.5±2.9, hospitalization time (days): 15.4±5.6 vs. 19.2±7.3, both P < 0.05], and the complication rate in nasointestinal tube group was obviously lower than that in nasogastric tube group [10% (5/50) vs. 36% (18/50), P < 0.05]. For patients with severe craniocerebral trauma treated with MV, the EN treatment by means of indwelling nasointestinal tube is helpful for the recovery of consciousness, improvement of nutritional indexes, reduction of incidences of complications such as reflux aspiration, etc. and shortening the course of disease, thus the method can obviously improve the patients quality of life.

Study for the Relationship between Lupus Nephritis and Anti-C1q Antibodies

Background: lupus nephritis (LN) is an inflammation of the kidney caused by systemic lupus erythematosus (SLE), a disease by the immune system. Anti-C1q antibodies have been found in many different systemic autoimmune diseases, they are strongly linked to immune complex disorder most prominently SLE and severe rheumatoid arthritis and have been suggested to be closely associated with lupus nephritis (LN). Generally anti-dsDNA antibodies have been acknowledged as an important tool in the diagnosis of SLE, however their predictive value as to the activity of the disease remains controversial, on the contrary anti-C1q antibodies appear to have a clear-cut relationship with renal complications of SLE not only have they been shown to play a pathogenic role in the development of lupus nephritis but also their serum levels correlate with the presence of active proliferation lupus nephritis. Aim of the study: this study aimed to investigate association between serum titer of anti-C1q antibody and disease manifestation of SLE. Methodology: the study was carried out in three different groups: healthy group, rheumatoid arthritis group and lupus nephritis group. All groups were subjected to determination of anti-C1q antibody, blood urea nitrogen (BUN) and serum creatinine. Results: there was no significant difference in BUN levels between the normal and rheumatoid arthritis groups in contrast there was a highly significant difference in BUN between the normal and lupus groups also, between the rheumatoid arthritis and lupus nephritis groups (p˂0.001). No significant difference was detected in serum creatinine levels between the normal and rheumatoid arthritis groups in there was a highly significant difference in serum creatinine between the normal and lupus groups and also between the rheumatoid arthritis and lupus nephritis groups (p˂0.001). No significant difference was realized in serum anti-C1q antibodies levels between the normal and rheumatoid arthritis groups in contrast there was a highly significant difference in serum anti-C1q antibodies between the normal and lupus groups and also between rheumatoid arthritis and lupus nephritis groups (p˂0.001). In the control group and rheumatoid arthritis groups, only BUN showed a highly significant positive correlation with serum creatinine concentration (r=0.906, r=0.404) and (P˂0.001, P˂0.05) respectively, while in lupus nephritis group, BUN showed a highly positive correlation with serum creatinine concentration (r=0.773, P˂0.001) also serum creatinine concentration showed a positive concentration with serum anti-C1q antibody (r=0.513, P˂0.05). Conclusion: the present study suggested that anti-C1q antibody might be a new parameter for the development of lupus nephritis since the increased of anti-ds DNA antibody and hypocomplementemia (C3 and C4) are serological markers of SLE activity, but they are not enough to identify which organ may be affected, while anti-C1q antibody either alone or in combination with other serological markers could give information of the diagnosis of a renal flare with 100% sensitivity and specificity.

Roflumilast enhances the renal protective effects of retinoids in an HIV-1 transgenic mouse model of rapidly progressive renal failure

Retinoic acid decreases proteinuria and glomerulosclerosis in several animal models of kidney disease by protecting podocytes from injury. Our recent in vitro studies suggest that all-trans retinoic acid induces podocyte differentiation by activating the retinoic acid receptor-α (RARα)/cAMP/PKA/CREB pathway. When used in combination with all-trans retinoic acid, an inhibitor of phosphodiesterase 4 further enhanced podocyte differentiation by increasing intracellular cAMP. Additionally, we found that Am580, a specific RARα agonist, has similar renal protective effects as all-trans retinoic acid in a rederived colony of HIV-1 transgenic mice with rapidly progressive renal failure (HIV-Tg) that mimics human HIV-associated nephropathy. Treatment with either the inhibitor of phoshodiesterase 4, roflumilast, or Am580 significantly reduced proteinuria, attenuated kidney injury, and improved podocyte differentiation in these HIV-Tg mice. Additional renal protective effects were found when roflumilast was combined with Am580. Consistent with the in vitro data, glomeruli from HIV-Tg mice treated with both Am580 and roflumilast had more active phosphorylated CREB than with either agent alone. Thus, phosphodiesterase 4 inhibitors could be used in combination with RARα agonists to provide additional renal protection.

Renal Function and Neurohormonal Changes Following Intravenous Infusions of Nitroglycerin Versus Nesiritide in Patients With Acute Decompensated Heart Failure

Background Rises in serum creatinine and efficacy have been reported as dose-related effects of nesiritide and nitroglycerin in acute decompensated heart failure (ADHF). However, no study has evaluated the comparative safety, efficacy, and biomarkers of optimally dosed nesiritide versus nitroglycerin in ADHF. Methods and Results Eighty-nine ADHF patients were prospectively randomized to receive either nesiritide (0.01 μg kg −1 min −1 ± bolus) or nitroglycerin (maximally tolerated doses by standard protocol). Blood urea nitrogen (BUN), and creatinine were obtained during 48 hours of intravenous infusion. B-Type natriuretic peptide (BNP) and N-terminal (NT) proBNP concentrations were measured during hospitalization. There were no significant differences in BUN, serum creatinine, creatinine clearance, or hospitalization and mortality. Although concentrations of BNP and NT-proBNP were significantly decreased over time, the comparative reductions between the 2 vasodilators were similar. Conclusions Nesiritide and nitroglycerin produce similar hemodynamic effects, do not worsen markers of renal function, and produce significant, yet similar, reductions in neurohormones over time. Both nitroglycerin at maximally titrated doses and nesiritide at standard doses are safe and effective in patients with ADHF who require vasodilator therapy.

Changes in blood urea nitrogen (BUN) concentration during pregnancy in the rat with or without obstructive uremia

Bilateral ureteral ligation changes the blood urea nitrogen (BUN) concentration in pregnant and non-pregnant rats. Marked increases of the BUN concentration occurred in both pregnant and non-pregnant specimens after ligation. The BUN concentration in sham-ligated rats did not change from day 16 through 19 of pregnancy, but increased on day 20 of pregnancy and thereafter. There was no significant difference in BUN between ligated pregnant rats on days 16 and 17 of pregnancy and ligated non-pregnant rats. As pregnancy progressed from day 18 onward, the BUN in ligated pregnant rats decreased when compared with that of ligated non-pregnant rats, but did not reach the level in sham-ligated pregnant rats. The BUN of mothers and fetuses both in the ligated and the sham-ligated groups were similar. Amniotic fluid urea nitrogen levels were higher than in blood on late fetal days. In ligated mothers, a significant relationship between maternal BUN and the number of fetuses was noted on day 22 of pregnancy. These results suggest that the fetal kidney becomes functional for excreting urea in late fetal life.
