Acute and Subacute Toxicity of Ruta Montana Extract to Female Rats: Effect on Liver, Kidneys and Ovaries

Ruta montana L. is an annual aromatic plant of the family rutaceae. Quantitative analysis of the methanolic crude extract of Ruta montana L. yielded 8.43%, whereas the qualitative analysis revealed the presence of alkaloid or coumarin. The Litchfield and Wilcoxon method calculated the LD50 of the crude methanolic extract of Ruta montana L. in Wistar albino female rats at 393.18 mg/kg. This allows the plant to be classified as moderately toxic. The subacute toxicity study of the methanolic crude extract of Ruta montana L. in female Wistar albino rats treated with 100 mg/kg (≈ 1/4 LD50) and intraperitoneally showed a significant increase in body weight of the rats treated at the 4th week. Animals treated and sacrificed after 30 days showed a disturbance of the relative mass of the organs. Biochemical parameters of hepatic function assessment showed a significant increase in PAL with elevation of AST and ALT, whereas those of renal function revealed a significant decrease in creatinine with an increase in urea. Hematologic parameters recorded a decrease in RBC, HGB and HCT. The histological sections of the treated rats reveal the existence of blood congestion in the central veins and liver tissues, foci of necrosis and steatosis in the liver, blood congestion and some glomerular atrophy in the kidneys, as well as blood congestions and developed follicles without oocytes in the ovaries.

Clinical manifestations and outcomes in tubulointerstitial nephritis and uveitis syndrome: a case report and a systematic review in China

PurposeTubulointerstitial nephritis and uveitis (TINU) syndrome is an uncommon disease. We present a confirmed case of TINU syndrome, and a systematic review of epidemiological characteristics, clinical manifestations, management, and outcomes in Chinese patients.MethodsA systematic search was carried out using defined terms and updated up to September 2022, in PubMed, Web of Science, Wanfang, CNKI, and VIP, to identify reported cases of TINU in China, according to PRISMA guidelines.ResultsAn 18-year-old boy presented with elevated serum creatinine and 24-h urine protein level of > 2 g. Inspection result revealed acute tubulointerstitial nephritis, and bilateral uveitis. The patient was diagnosed with TINU syndrome and received treatment with methylprednisolone sodium succinate, which resulted in a significant decrease in creatinine and urinary protein levels. Systematic review identified 35 publications that met the inclusion criteria. A total of 71 cases were included in this article, of which 70 were from publications and 1 was from our hospital. The median age at onset was 42 years and was significantly lower in males than females (P < 0.05). The symptoms of uveitis often occurred after kidney injury (54%) and most uveitis was anterior (55%) and bilateral (75%). Among the 51 patients who were followed up for more than 6 months, 24 had recurrent ocular symptoms or progression to chronic uveitis. Twenty patients experienced chronic or progressive kidney disease.ConclusionTINU syndrome is prone to misdiagnosis because kidney damage may not occur simultaneously with uveitis. The incidence of kidney sequelae in children is lower than that in adults, and glucocorticoids are the preferred treatment.INPLASY registration number INPLASY202350050.

The Effects of Asystasia vogeliana Benth. on Wistar Rat Liver Health, Kidney Function, and Lipid Profile

Aims: This study investigated the effects of long term consumption of A. vogeliana leaf on the liver health, kidney function, and lipid profile of female Wistar rats. This was with a view to assessing the safety and potential health effects of the plant extract.&#x0D; Study Design: The study employed in vivo animal model in Wistar rats.&#x0D; Place and Duration of Study: Department of Biochemistry and Molecular Biology, Obafemi Awolowo University, Ile-Ife, Nigeria, between June 2019 and February 2020.&#x0D; Methodology: Acute oral toxicity and LD50 were determined. Animals were randomized into three groups (n = 6) and treated as follows: Group 1 (normal control; distilled water), Group 2 (250 mg/kg), and Group 3 (500 mg/kg) for 21 days. Animals were sacrificed on 22nd day and plasma was analyzed for liver-kidney biomarkers: aspartate aminotransferases (AST), alanine aminotransferases (ALT), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, urea, and creatinine. Also, the lipid biomarkers (total cholesterol TC), triglyceride TG, high-density lipoprotein HDL, and low-density lipoprotein-cholesterol LDL), and atherogenic indices were determined.&#x0D; Results: The result showed LD50 &gt; 2000 mg/kg. A non-significant difference was observed in ALT activity, total bilirubin, direct bilirubin, and urea levels. Significant (p&lt;0.05) elevations in AST and ALP, and a significant decrease in creatinine were observed in the treated group, suggesting detrimental effect on the kidney health. TC, TG, and LDL were significantly high, whereas HDL was significantly low in the treated group. Similarly, significant increases in non-HDL, atherogenic coefficient (Ac), coronary risk index-1 (CRI-1), and 2 (CRI-2), were observed in the treated groups, suggesting a likelihood for cardiovascular diseases.&#x0D; Conclusion: The study concluded that prolonged administration of A. vogeliana leaf impacted the kidneys and induced an elevated lipid profile and a sharp decrease in HDL. Therefore, prolonged use of A. vogeliana should be discouraged.

Low serum creatinine, a surrogate marker of muscle mass, correlates with insulin sensitivity in nonhuman primates.

Decreased serum creatinine levels are associated with increased risk of type 2 diabetes (T2DM) in humans, however, its association with muscle mass and insulin sensitivity have not been studied in NHPs. Retrospective data of 229 adult NHPs were studied for association of serum creatinine levels with muscle mass and onset of T2DM. Serum creatinine levels were positively correlated with lean muscle mass in nondiabetic (non-DM), male and female NHPs. Aged NHPs had significantly reduced lean muscle mass and corresponding creatinine levels compared to young age groups (p < .001). Creatinine was positively correlated with insulin sensitivity in nonDM male NHPs and significant decrease in creatinine was observed in T2DM (p < .001) compared to same age group nonDM NHPs. The pathophysiology of T2DM in NHPs is similar to humans, low creatinine further provides utility of surrogate biomarkers of lower muscle mass and risk factor for T2DM NHPs.

Effects of Telfairia occidentalis and Ipomoea batatas on Biochemical and Antioxidant Assay of African Catfish (Clarias gariepinus)

This toxicological study was carried out to determine possible adverse effects of Telfairia occidentalis and Ipomoea batatas leaves in Clarias gariepinus. Ninety-six Clarias gariepinus growers (431.25±6.13 g) randomly distributed into four feeding groups were fed with herbal leaf diet containing 20 g/kg of T. occidentalis (group A), 100 g/kg of I. batatas (group B), mixture of 10 g/kg of T. occidentalis and 50 g/kg I. batatas (group C) and basal diet (group D) which served as the control group. After a 40-day feeding period, blood samples were collected for serum biochemical assay and organs were harvested for antioxidant and tissue biochemical assay. A significant decrease in creatinine was observed in the fish in group C when compared with those in group D. Also, there was no significant difference in the liver superoxide dismutase activity across all feeding groups but no significant increase in the intestinal superoxide dismutase activity of the fish in group C when compared to those in group A. There were no significant differences in the values of liver enzyme markers and lipid profile across all feeding groups. However, a significant increase in the level of intestinal malondialdehyde was observed in the fish in group B when compared with those in groups A and D. This study revealed that oral administration of a combination of T. occidentalis (10 g/kg) and I. batatas (50 g/kg) leaves enhanced antioxidant enzymes and is recommended for protection against oxidative stress in Clarias gariepinus.

Prophylactic Anti-Osteoporotic Effect of Matricaria chamomilla L. Flower Using Steroid-Induced Osteoporosis in Rat Model and Molecular Modelling Approaches.

The anti-osteoporotic activity of ethanol extract from the Matricaria chamomilla L. flower was evaluated using steroid-induced osteoporosis in a rat model for the first time. Biochemical parameters such as serum calcium, phosphate, magnesium, creatinine, and alkaline phosphatase were assessed. At a 400 mg/kg body weight dose, the extract showed 54.01% and 27.73% reduction in serum calcium and phosphate ions serum levels, respectively. Meanwhile, it showed a 20% elevation in serum magnesium level, compared to the steroid-treated group. It also showed a significant decrease in creatinine and alkaline phosphatase levels, by 29.41% and 27.83%, respectively. The obtained results were further supported by biomechanical analyses, which revealed that a 400 mg/kg body weight dose of the flower extract increased bone strength and thickness. At the same time, it does not affect the bone length, compared to the diseased group. Histopathological examination revealed that the extract showed a significant increase in trabecular thickness, and it had restored the architecture of the cortical and trabecular structure with well-organized bone matrix. The possible inhibitory effect of the major phenolic compounds identified from the plant extract on cathepsin K was investigated using molecular docking. Rutin (4) had the best-fitting score within the active site, as evidenced by the free binding energy, (∆G = −54.19 Kcal/mol). ADMET/TOPKAT revealed that the examined compounds had variable pharmacodynamics and pharmacokinetic properties that could be improved to enhance the bioavailability during incorporation in various dosage forms. Thus, it can be concluded that this plant extract showed potential therapeutic benefits for osteoporosis.

Acute and sub-acute toxicity studies of Methanol stem bark extract of Cadaba farinosa (Forssk) in wistar rats.

The study focused on evaluating the toxicity profile of the methanol stem bark extract of Cadaba farinose (Forssk), considering possibilities of adverse effects arising from continual use of herbal plants especially in the management of long-term conditions. Cadaba farinosa is a slender shrub plant widely used traditionally in the treatment of various diseases such as diabetes mellitus, inflammations, rheumatic pains and various infections including skin and intestine both in Africa and India. The acute toxicity study and sub-acute toxicity studies were carried out in Wistar rats using Lorkes Method (1983) and the OECD Guidelines 425. For the sub-acute toxicity studies, twenty rats weighing between 120 and 170g were randomly grouped into 4 groups of 5 rats each. Group 1 (control) received 10ml/kg of distilled water and the others received doses of 40, 200 and 1000mg/kg p.o of extract for 28 days. The acute toxicity revealed no mortality or behavioural signs of toxicity in both phases up to 5000mg/kg. The haematological indices revealed a significant (p&lt;0.05) increase in the WBC count, MCV and PLT of the groups that received 1000mg/kg of the extract after treatment for 28 days. The liver function test showed a significant increase (p&lt;0.05) in AST and ALT. Renal indices showed a significant decrease in creatinine and a significant increase (p&lt;0.05) in plasma Na+, K+ and Cl- ion concentration across the groups. Histopathological section of the spleen revealed follicular hyperplasia. The results suggest that the plant could be slightly toxic to the liver and the spleen on long-term use.

The impact of movement, physical activity and position on urine production: A pilot study.

Many different internal factors have been proven to influence urine production such as age, weight, and quality of sleep. External factors such as consumption of caffeine and fluid consumption have been shown to have an impact on urine production. To investigate the impact of movement, physical activity and position on urine production. This prospective observational study was executed at Ghent University Hospital, Belgium. Study participation was open for anyone visiting the hospital. Participants collected one basic and two extended 24-hour urine collections and filled in questionnaires concerning their general health and physical activity. Urinary levels of osmolality, sodium and creatinine were determined. Data on movement, physical activity and position was described. An increase in body movement leads to a significant increase in diuresis during daytime, night-time, and 24hours (P=.002, P<.001, and P<.001, respectively). An increase in body movement leads to a significant decrease in osmolality during night-time and 24hours (P=.009, and P=.004, respectively). However, no significant influence of movement on osmolality was found during daytime (P=.12). An increase in body movement leads to a significant decrease in creatinine during daytime, night-time and 24hours (P=.001, <0.001, and P<.001, respectively). An increase in body movement leads to a significant increase in sodium during daytime (P=.046) but this was statistically significant during night-time and 24hours (P=.32, and P=.84 respectively). Our study demonstrates a statistically significant association of movement, physical activity, and position with urine production. It would therefore be interesting to explore this association further with the use of new technology to have more accurate data. Here, lays a potential role for conservative measurements and lifestyle adaptations in the management of patients with bothersome LUTS and more precisely nocturia.

Outcomes of Renal Function in Cardiogenic Shock Patients With or Without Mechanical Circulatory Support

Background: The objective of the study was to compare the renal outcomes in patients presenting with all-cause cardiogenic shock who were supported by either Impella devices (Abiomed, Danvers, MA), intra-aortic balloon pump (IABP), or vasopressors alone. Outcomes of cardiogenic shock remain poor even with the advancement of early revascularization and circulatory supportive care. Percutaneous mechanical circulatory support (MCS) device has emerged as an effective strategy in protecting end organ function especially renal function during high risk percutaneous coronary intervention (PCI) and in patients with cardiogenic shock. Currently, comparative data amongst various MCS modalities and their association with improvement of renal function in cardiogenic shock patients have not been well characterized. Methods: Data from New Jersey Cardiac Catheterization Data registry of cardiogenic shock patients from a single tertiary care institution that underwent cardiac catheterization and the modality used to treat were obtained, either with Impella devices, IABP, or treatment with vasopressors alone. Retrospective chart review was conducted to assess the incidence of acute kidney injury (AKI) on patients with cardiogenic shock prior to and after cardiac catheterization and renal function was evaluated over the course of 96 h after cardiac catheterization. Statistical analysis was performed to ascertain significant difference in creatinine and estimated glomerular filtration rate (eGFR) in patients who received Impella devices, IABP, or were treated with vasopressors alone. Results: A total of 61 all-cause cardiogenic shock patients met the inclusion and exclusion criteria and were included in the study with 19 receiving IABPs, 15 receiving Impella devices, and 27 treated with vasopressors alone. Baseline characteristics among these three groups did not show any statistically significant difference. A total of 29 cardiogenic shock patients had experienced AKI prior to cardiac catheterization in which those receiving Impella devices showed statistically significant decrease in creatinine and increase in eGFR at 72 and 96 h (P < 0.05) compared to baseline. Within the same cohort, Impella group showed statistically significant lower creatinine at 96 h when compared to IABP. Patients that experienced AKI after cardiac catheterization did not show any statistically significant changes in renal function regardless of modality used. Conclusion: The results of our study suggest that Impella devices improve renal function in all-cause cardiogenic shock patients who experience AKI prior to undergoing cardiac catheterization.

Toxicological evaluation of banana and milk combination as incompatible diet - An experimental exploration of Samyoga viruddha concept

BackgroundFood is the basic requirement and an essential part of all living beings which sustains life. A lot of emphasize has been given to food in the classics of Ayurveda and a detailed description of food which are both wholesome and unwholesome have been described. Viruddhahara (incompatible food) is a unique concept explained in Ayurveda which, in long run, may be harmful to the body. Objective(s)Intake of Kadaliphala (Musa paradisiaca. Linn, a variety of banana) and cow milk is an example of Samyoga Viruddha (incompatibility with reference to combination of things). This combination is routinely consumed by people. The present study was planned to evaluate the toxicological implication of their combination on wistar rats. Materials and methodsA subacute toxicity study was conducted on Wistar rats following the repeated dose 28-day oral toxicity study in rodents, 407 - OECD guidelines. Different haematological and biochemical parameters along with histopathology of important organs were carried out to assess the toxicological implication of the combination. ResultsRepeated administration of the combination of Kadaliphala (Banana) and cow milk showed statistically significant increase in SGOT & urea and statistically significant decrease in creatinine. Significant decrease was observed in the food intake, faecal wet weight and faecal water in the 7th day of study, food conversion ratio in the 14th day of study, in the food intake, faecal wet weight and faecal water in the 21st day of study and significant decrease in the food conversion ratio in the 28th day of study. In histopathological examination, the test drug administered group showed mild to moderate myocarditis in the sections from heart. In sections from liver of two rats of test group, diffused micro fatty changes were observed. In sections from spleen; mild to moderate increase in the white pulp portion was observed. ConclusionMarked variation in SGOT, urea and creatinine levels and alteration in sections of heart, liver and spleen are indicative of mild toxicological implications of the combination of banana and milk. Continuous intake of this incompatible combination may hence prove harmful to the body.

Renoprotective effect of carbamylated darbepoetin and udenafil in ischemia-reperfusion of rat kidney due to the effect of preconditioning and inhibition of nuclear factor kappa B

Introduction: Acute kidney injury is a widespread complication in hospitalized patients, with a high mortality rate and long-term complications affecting prognosis and quality of life and with high human and financial costs. In addition, to date, no clear algorithm for the prevention of this type of damage has been developed.&#x0D; Materials and methods: The research was carried out on male Wistar rats. A 40-minute renal ischemia-reperfusion model was used to model acute kidney injury. Further, the renoprotective properties of carbamylated darbepoetin, udenafil and their combination were assessed based on the analysis of the biochemical studies’ results, dynamics of the renal status and the renal microvasculature, and the pathomorphological picture. A series of experiments was also carried out to assess the contribution of adenosine triphosphate-dependent potassium channels and nuclear factor kappa B to the renoprotective properties of the said agents.&#x0D; Results and discussion: Prophylactic administration of carbamylated darbepoetin at a dose of 50 μg/kg and udenafil at a dose of 8.7 mg/kg led to a statistically significant decrease in creatinine and blood urea nitrogen, an increase in glomerular filtration rate with a simultaneous decrease in fractional excretion of sodium, as well as an increase in the level of microcirculation in the kidneys and a decrease in the severity of damage according to the data of a pathomor­phological examination at all time points of the experiment. A higher efficiency of correcting ischemic and reperfusion renal injuries was observed when using a combination of the said pharmacological agents. A series of experiments with glibenclamide demonstrated that its preliminary administration levels the renoprotective properties of carbamylated darbepoetin and udenafil. The ability of the studied pharmacological agents to reduce lipopolysaccharide-induced ex­pression of nuclear factor kappa B in mononuclear cells was also demonstrated. The results of the research suggest that the renoprotective effects of carbamylated darbepoetin, udenafil, and their combination are realized through ATP-de­pendent potassium channels and nuclear factor kappa B.&#x0D; Conclusion: Pharmacological preconditioning with carbamylated darbepoetin and udenafil reduces the severity of acute kidney injury induced by ischemia-reperfusion.

Iron(IV) hexahydrazide clathrochelate complexes: the chronic toxicity study

One of the main tasks in the fight against anemia is to carry out preventive measures, to develop and to introduce new preparations containing iron, to provide the pharmaceutical market with anti-anemic agents. That's why to investigate the chronic toxic effect of Iron(IV) hexahydrazide clathrochelate (new iron-containing drug) in mice was the article's aim. The study of chronic toxic effect of Iron(IV) clathrochelate was performed on 45 white mice (19–25 g) separated into 3 groups: control (I) and two experimental (II and III). Animals of II and III groups were daily fed the water solution of Iron(IV) clathrochelate at a rate of 125.8 and 251.6 mg/kg of body weight, respectively. It was monitored the dynamics of body weight of white mice, relative coefficients of the mass of internal organs, hemoglobin content and morphological parameters of blood, biochemical indices of blood serum on the 10th, 20th and 30th day of the experiment. It was established a decrease of body weight by 16–21% and relative weight indices of internal organs (liver, kidney, heart, and spleen) – by 5– 43% in white mice of II and III experimental groups, respectively. Changes in the morphological composition of the blood showed stimulation of leukocytopoiesis. A significant decrease in creatinine (hypocreatinemia) and uric acid (hypouricemia) was observed, which indicates an increase in the filtration capacity of the renal glomeruli. Complex studies of the effect of Iron(IV) clathrochelate solution (at a dose of 125.8 and 251.6 mg/kg of body weight) did not cause any visible signs of intoxication and death of animals at the first time. Iron(IV) clathrochelate solution (at a dose of 125.8 mg/kg of body weight) is demonstrated more safe effect.

Retrospective evaluation of paired plasma creatinine and chloride concentrations following hetastarch administration in anesthetized dogs (2002-2015): 244 cases.

To evaluate changes in serum creatinine and chloride concentrations in anesthetized dogs that received 6% hydroxyethyl starch (HES) 670/0.7. Retrospective case series, 2002-2015. University veterinary teaching hospital. Two hundred forty-four client-owned dogs undergoing general anesthesia that received an HES solution. None. Medical records of dogs that received an HES solution (6%, 670/0.7) while under general anesthesia during the study period were reviewed. Information obtained from the medical record included patient signalment, reason for anesthesia or diagnosis, body weight, amount of HES solution administered, pre- and postanesthesia creatinine value, pre- and postanesthesia chloride value, and day interval between measurements. Corrected chloride values were used for all statistical analysis. Dogs received a median dose of 6.3 mL/kg hetastarch during anesthesia. Median preanesthesia creatinine and corrected chloride values were 79.5μmol/L (0.9mg/dL) (range 8.8-689.5μmol/L [0.1-7.8mg/dL]) and 111mmol/L (111mEq/L) (range 80-123mmol/L [80-123mg/dL]), respectively. Median postanesthesia creatinine was 57.4μmol/L (0.65mg/dL) (8.8-716μmol/L [0.1-8.1mg/dL]). Median postanesthesia corrected chloride was 115mmol/L (115mEq/L) (range 87.5-129.6mmol/L [87.5-129.6mEq/L]). Mann-Whitney test analysis revealed a significant decrease in creatinine (Δ Cr 17.7μmol/L [0.2mg/dL], P < 0.01) and a significant increase in corrected chloride (Δ Cl 4.1mmol/L [4.1mEq/L], P < 0.01) between pre- and postanesthesia values. In a mixed population of hospitalized dogs undergoing general anesthesia that received a median dose of 6 mL/kg of HES, creatinine was lower and chloride was higher in the postanesthetic than in the preanesthetic period. The clinical significance of these changes and the role that HES administration played in them relative to concurrent therapies is unknown.

Effect of curcumin and curcumin nanoparticles against lead induced nephrotoxicity.

The aim of the present study was to examine the protective effect of curcumin (CUR) and curcumin nanoparticles (CURNPs) as antioxidants on the nephrotoxicity induced by lead (Pb). CUR (60 mg/kg b.w) and CURNPs (30 mg/kg b.w) were evaluated using Pb (30 mg/kg b.w.) induced oxidative renal damage in rats. Administration of Pb significantly (p<0.001) increased the levels of renal function test such as creatinine (CRN) and blood urea nitrogen (BUN) and uric acid (UA). Furthermore, Pb significantly decreased glutathione (GSH) levels, superoxide dismutase (SOD), glutathione reductase (GR), catalase (CAT) and glutathione peroxidase (GPx) activities (p<0.001). CUR and CURNPs displayed a renal protective effect as evident by significant decrease in CRN, BUN, UA levels and elevated the antioxidant status of renal tissues. The administration of Pb also induced histopathological changes in renal tissue; however, in groups treated by CUR and CURNPs, there was amelioration in pathological changes in renal tissue. These findings suggest that Nano CUR could be a potential compound in combating the oxidative damage of renal tissue as it increases curcumin bioavailability.

Potential role of estradiol in ovariectomy-induced derangement of renal endocrine functions

Menopause is an important physiological event associated with structural and functional changes in the kidneys. An animal model of bilateral ovariectomy was used to study the effects of estrogen depletion, replacement and antiestrogen on renal structure and endocrine function. Sixty female rats were divided into six groups; group I was the control group, the remaining five groups underwent ovariectomy: group II received no treatment. The other groups received estradiol in group III, tamoxifen in group IV, estradiol followed by tamoxifen in group V and tamoxifen followed by estradiol in group VI. Serum creatinine, blood urea nitrogen, and endocrine functions of kidney were measured. Tissue samples were examined both microscopically for beta estrogen receptors and ultrastructurally for cell changes. Groups II, IV & VI showed a significant increase in creatinine, blood urea nitrogen, renal malondialdehyde, renal erythropoietin, plasma renin and plasma prostaglandin E2 and a significant decrease in renal antioxidants and serum vitamin D3. Groups III &V had a significant decrease in creatinine, blood urea nitrogen, renal malondialdehyde and renal erythropoietin with an increase in renal antioxidants, plasma prostaglandin E2 and serum vitamin D3. Histopathological and ultrastructural examinations revealed atrophic tubular changes in group II. The changes were less marked in groups III &V and more extensive in groups IV & VI. Estrogen receptor beta staining showed progressively increased expression in the absence of estrogen. Structural and most endocrine functions of the kidney were significantly affected by estradiol deficiency. Estradiol replacement exhibited a protective effect on renal tissue and endocrine functions.

A retrospective study of anesthesia for subcutaneous ureteral bypass placement in cats: 27 cases.

The goals of this retrospective clinical case series study were to describe the management of anesthesia, and to report perioperative complications in cats undergoing subcutaneous ureteral bypass (SUB) placement due to ureteral obstruction. Medical records of client-owned cats with ureteral obstruction and anesthetized for SUB placement between 2012 and 2015 in a veterinary teaching hospital were reviewed. Twenty-seven cases were identified. Duration of anesthesia and surgery (mean ± standard deviation) were 215 ± 42 min and 148 ± 36 min, respectively. Hypothermia was the most common intraoperative complication. Hypotension, hypocapnia, hypertension and bradycardia were also frequently observed. Out of 22 cats who experienced intraoperative hypotension, 17 received inotropes and vasopressors. There was a significant decrease in creatinine (P=0.008) and total solids (P=0.007) after SUB placement when compared with baseline values. Postoperative complications included pain, anorexia, nausea, hypertension, and urinary tract-related problems. No death occurred in the postoperative period. Successful management of anesthesia for SUB placement involves rigorous anesthetic monitoring and immediate treatment of complications. Perioperative complications appear to be common. This study could not identify risk factors associated with this procedure.

Livolin Forte Ameliorates Cadmium-Induced Kidney Injury in Wistar Rats

Abstract The kidney, which is an integral part of the drug excretion system, was reported as one of the targets of cadmium toxicity. Early events of cadmium toxicity in the cell include a decrease in cell membrane fluidity, breakdown of its integrity, and impairment of its repair mechanisms. Phosphatidylcholine and vitamin E have a marked fluidizing effect on cellular membranes. We hypothesized that Livolin forte (LIV) could attenuate kidney damage induced by cadmium in rats. Twenty-five adult male Wistar rats were divided into five groups of five rats each: group I (control group) received 0.3 ml/kg/day of propylene glycol for six weeks; group II was given 5 mg/kg/day of cadmium (Cd) i.p for 5 consecutive days; group III rats were treated in a similar way as group II but were allowed a recovery period of 4 weeks; group IV was treated with LIV (5.2 mg/kg/day) for a period of 4 weeks after inducing renal injury with Cd similarly to group II; and group V was allowed a recovery period of 2 weeks after a 4-week LIV treatment (5.2 mg/kg/day) following Cd administration. A significant increase in plasma creatinine, urea, uric acid, and TBARS were observed in groups II and III compared to the control rats. Significant reductions in total protein, glucose, and GSH activity were also recorded. The urine concentrations of creatinine, urea, and uric acid in groups II and III were significantly lower than the control group. Th is finding was accompanied by a significant decrease in creatinine and urea clearance. Post-treatment with LIV caused significant decreases in plasma creatinine, urea, uric acid, and TBARS. Significant increases in total protein, glucose, and GSH activity of groups IV and V were observed compared to group II. A significant increase in urine concentrations of creatinine, urea, and uric acid and significant decreases in total protein, glucose, and GSH activity were observed in groups IV and V compared to group II. Photomicrographs of the rat kidneys in groups IV and V showed an improvement in the histology of their renal tissue when compared to group II, with features similar to the control rats. Additionally, group III showed an improvement in the histoarchitecture of the kidney compared with group II, although occasional atrophy of some glomeruli and shrinking of renal corpuscles was observed. In conclusion, the results of this study indicated that LIV administration ameliorated Cd-induced kidney injury in rats. Thus, LIV represents a prospective therapeutic choice to prevent kidney injury inflicted by Cd exposure.

Effect of moderate aerobic exercises on kidney function and lipid profile in chronic kidney disease patients

Background Chronic kidney disease (CKD) is an important risk factor for cardiovascular diseases and mortality. Physical inactivity is a modifiable risk factor that may affect the development and course of CKD. It is well established that exercise improves a number of metabolic factors, as well as blood pressure and insulin resistance, which would be expected to preserve renal function and lower cardiovascular risks. Aim of the study The aim of this study was to investigate the effect of treadmill walking exercise (moderate aerobic exercise) on kidney function tests and lipid profile in patients with CKD stages 3 and 4. Patients and methods Fifty patients with CKD stages 3 and 4 participated in the study. They were selected from the outpatient clinic of Nephrology Department, Zagazig University Hospitals (during the period from January 2015 to June 2015). Their ages ranged from 45 to 55 years. They were divided into two groups: the study group (group B), which included 30 patients who received moderate aerobic exercises on treadmill three times per week for 3 months plus their medications, and the control group (group A), which comprised 20 patients who received their medications only with no training exercises. Urine and blood samples were collected for determining glomerular filtration rate (GFR), serum blood urea, serum creatinine, and serum lipid profile before the initiation of the training program and after the completion of the study (after 3 months). Results There was a statistically highly significant decrease in creatinine, blood urea, triglyceride (TG), cholesterol, and low-density lipoprotein (LDL), and an increase in GFR and high-density lipoprotein (HDL) (P Conclusion It can be concluded that moderate aerobic exercises improve kidney function tests and lipid profile and can delay progression of CKD stages 3 and 4.

Evaluation of Performance of Date Palm Pollen on Urea and Creatinine Levels in Adult Female Rats Exposed to Lead Acetate Intoxication

Background and objective: exposure to lead continues to a serious public problem. The objective is to elucidate the effect of lead acetate exposure on serum Concentration of urea and creatinine in adult female rats.Methods: Forty eight adults female rats divided in to four groups (12 rats/group) .Group 1, (T1) ,given date palm pollen (150 mg/kg. B.W.) Group 2,(T2) given lead acetate (10mg/kg. B.W.), group 3, (T3) given lead acetate (10mg/kg.B.W.) and date palm pollen (150 mg/kg. B.W) for 6 weeks, Group 4(Control) ,given distilled water. Serum concentration of urea and creatinine was evaluated via ELISA method for all groups.Results: The mean concentration of urea showed no significant difference between,(T1) and (T3) while in T2 a significant (p < o.o5) increase in urea concentration compared to T1&T3 . There was no significant difference within groups in urea concentration. Group (T1) exposed to DPP showed no significant decrease in serum creatinine on zero,14 , 28 day & 42 day post exposure respectively . Group (T2) exposed to lead acetate showed significant increase of creatinine concentration compared with control and (T1) group .Group (T3) showed significant decrease in creatinine levels compared with T2 group and these levels become closely to control group. Histological changes indicated that DPP significantly meliorate the toxic effects of lead acetate in glomeruli, collecting tubules associated with obvious decrease in inflammatory response.Conclusion: DPP has the ability to counteract the toxic effect of lead acetate associated with improvement of renal histology and serum concentration of urea and creatinine.
