Propolis ameliorates renal, liver, and pancreatic lesions in Wistar rats.

This study aimed to evaluate the potential of ethanolic extract of propolis on the secondary lesions of the liver, renal, and pancreatic that were derived by primary colorectal cancer, and comparison of the ethanolic extract of propolis with the vitamin E. The groups included the control, ethanolic extract of propolis, vitamin E, dimethylhydrazine, dimethylhydrazine + ethanolic extract of propolis, and dimethylhydrazine + vitamin E. After 13 weeks of treatment, the blood and tissue samples were taken from all the rats, and alanine transaminase, aspartate transaminase, alkaline phosphatase, uric acid, creatinine, blood urea nitrogen, insulin, amylase, and lipase indices along with the tissue pathological examination of the kidney, liver, and pancreas were evaluated. Ethanolic extract of propolis effectively alleviated the colorectal cancer-induced secondary lesions in the liver by significantly lowering the alanine transaminase significantly. Ethanolic extract of propolis significantly decreased uric acid in rats; and also significantly elevated the pancreatic insulin. In addition, inflammation and cell necrosis indices in all these tissues were significantly reduced when ethanolic extract of propolis was consumed compared to the dimethylhydrazine group. It seemed ethanolic extract of propolis showed high antioxidant, anticancer, and anti-inflammatory potentials, and can be used practically to reduce the side lesions of colorectal cancer.

Priestia megaterium ASC-1 Isolated from Pickled Cabbage Ameliorates Hyperuricemia by Degrading Uric Acid in Rats.

Pickled cabbage, a traditional fermented food rich in functional microorganisms, can effectively control hyperuricemia and gout. In this study, a Priestia megaterium ASC-1 strain with strong uric acid (UA) degradation ability was isolated from pickled cabbage. After oral administration for 15 days, ASC-1 was stably colonized in the rats in this study. ASC-1 significantly reduced UA levels (67.24%) in hyperuricemic rats. Additionally, ASC-1 alleviated hyperuricemia-related inflammatory response, oxidative stress, and blood urea nitrogen. Intestinal microbial diversity results showed that ASC-1 restored intestinal injury and gut flora dysbiosis caused by hyperuricemia. These findings suggest that P. megaterium ASC-1 may be used as a therapeutic adjuvant for the treatment of hyperuricemia.

Effect of granules made by new-medicinal parts of Crocus sativus on hyperuricemia in rats and its mechanism

To explore the effect of the granules made by new-medicinal parts of Crocus sativus(NMPCS) on hyperuricemia(HUA) in rats, the rat model of HUA was established by intramuscular injection of 3% potassium oxonate and intraperitoneal injection of 4% pyrazinamide. The content of serum uric acid was monitored every week for 3 consecutive weeks. After the experiment, the levels of serum uric acid, urine uric acid, serum creatinine, blood urea nitrogen(BUN), and xanthine oxidase(XOD) were determined. The protein and gene expressions of XOD were determined by Western blot method and fluorescence quantitative polymerase chain reaction(qPCR), and the morphological changes in the liver tissue were performed by hematoxylin-eosin(HE) staining. The results showed that as compared with the model group, the levels of serum uric acid in the positive drug group and the low, medium, and high-dose NMPCS groups were lower(P<0.05), the levels of urine uric acid in the high-dose NMPCS group were decreased(P<0.01), and there was no statistical difference in the medium and low-dose NMPCS groups. The levels of BUN in the high and low-dose NMPCS groups were decreased(P<0.05), and the levels of serum creatinine did not change in the administration groups. The positive drug group and the low, medium, and high-dose NMPCS groups significantly reduced the liver damage, with only a few hepatocytes vacuolization and a small number of red blood cells in the central venous area. The nephridial tissue structure was slightly abnormal, with a small number of red blood cell infiltration, and no obvious inflammatory cell infiltration was found in the glomerulus in these groups. No degeneration was found in renal tubular epithelial cells, with mild glomerular and tubular lesions and a small amount of sodium urate deposition and crystallization in the positive drug group and the low, medium, and high-dose NMPCS groups. The relative protein expressions of XOD in the positive drug group and the high dose NMPCS group were decreased(P<0.05), and the relative mRNA expressions of XOD in the positive drug group and the high and low-dose NMPCS groups were decreased as well(P<0.05). The above results show that NMPCS reduces uric acid in rats with HUA by regulating XOD, which provides a certain experimental basis for the development of NMPCS as a new medicine for the treatment of HUA.

Hyperhomocysteinemia and Risk Factors of Metabolic Syndrome in Obese Children

Background and Aims: Hyperhomocysteinemia is one of the factors of risk implied in the development of cardiovascular Heart diseases (CHD). Obesity is associated with metabolic anomalies and insulin resistance constituting metabolic syndrome, the aggregate of factors risk of diabetes type 2 and cardiovascular complications. Objectives: The purpose of this work is to determine the levels of serum homocystein in obese children and adolescents and to establish the correlations between homocysteinemia and the components of metabolic syndrome. Patients and methods: The study was carried out on 67 children including 35 obese children (23 Boys, 12 Girls) old of 1 year 8 months at 16 years 4 months (average ± DS: 10.35 ± 3.5 years), with IMC means: 26.5 ± 3.8 kg/m2 and 32 no obese children (12 Boys, 20 Girls) who have an average age of 10 ± 4.6 years, them IMC means is: 16.47 ± 3.28 kg/m2 . The serum lipids are assessed by the enzymatic method, the levels of serum homocystein is determined by HPLC, the insulinemia is determined by technique ELISA. Index of insulin resistance HOMA and the cell ß function (Fc.ß) were calculated according to a formula using the glycemia and the insulinemia. Results: The homocysteinemia high in the obese children is significantly compared with that found in no obese children of the same age (10.6 ± 2.9 vs 7.2 ± 1.3 ?mol/l, p12 ?mol/l. In our present study, we noticed significantly higher, serum levels average of total cholesterol, LDL cholesterol and triglycerides (P<0,001) in obese children compared to found in no obese or healthy children. There is a significant increase in the rate of uric acid, insulinemia index of insulin resistance (HOMA-IR) (P<0,001) and Fc.ß (P<0,001), reflection of the hepatic insulin resistance. The serum homocystein levels correlate with body mass index (BMI), systolic blood pressure and in particular with uric acid levels. Conclusion: Hyperhomocysteinemia can be associated with metabolic syndrome and varies independently of the components of metabolic syndrome and other factors of risk early stage of the arterial attack. Thus, hyperhomocysteinemia is a predictive marker the development cardiovascular heart disease in obese youths.

The effect of spices Coriandrum sativum L., Trigonella foenum-graecum L., Pimpinella anisum L., and their combinations on growth performance, carcass trait, and hematobiochemical parameters in broiler chicken.

Background and Aim:The incorporation of herbs and species has been shown to enrich the food with antioxidants and bioactive antimicrobial compounds, thereby preserving the safety and productivity of broiler chicken production. This study aimed to determine the effects of three phytogenic feed additives (PHT) on certain zootechnical and hematobiochemical parameters in broiler chickens. Coriandrum sativum L. (coriander), Pimpinella anisum L. (green anise), and Trigonella foenum-graecum L. (fenugreek) were used to formulate the PHT.Materials and Methods:A total of 360 1-day-old Cobb broilers for 42 days were randomly assigned to four dietary treatment groups: A control group (CTLG) and three groups fed a basal diet supplemented with 3% of coriander (PHT1G), 3% of a combination 50% coriander-50% fenugreek (PHT2G), and finally, 3% of a combination 50% coriander-50% green anise (PHT3G), respectively, and each experimental group included three repetitions of 30 birds. Zootechnical parameters, carcass productivity, and hematobiochemical properties were measured.Results:The birds in the PHT3G had the greatest body weight and organ weight (p < 0.05). However, the weight of abdominal fat remained unchanged. The same group of broilers had a significantly (p < 0.05) higher lymphocyte level of 120.103/μL, followed by the PHT2G, which had 80.103/μL. The levels of monocytes in the PHT2G and PHT3G were 66.103/μL and 60.103/μL, respectively. Regarding granulocytes, we observed 200.103/μL in the PHT2 group and 102.103/μL in the PHT3G. There was a statistically significant difference (p < 0.05) between the uric acid levels of the PHT1G, PHT2G, and PHT3G, with 50.4 mg/L, 59.84 mg/L, and 47.29 mg/L, respectively. All experimental groups had significantly lower uric acid concentrations than the control group (84.36 mg/L).Conclusion:The use of phytogenic feed additives may positively affect both weight gain and hematobiochemical parameters in broiler chicken, particularly the levels of various white blood cell subtypes and the uric acid rate.

Effect of High-altitude Hypoxia Environment on Uric Acid Excretion, Desmin Protein Level in Podocytes, and Na+-K+- ATPase Activity.

To investigate the oxidative stress and adaptive compensation of kidneys in rats in high-altitude hypoxia environments, 20 Wistar rats (3 months) were randomly and equally grouped. The rats in the test group were fed in a low-pressure oxygen chamber, and those in the control group (controls) were fed in a normal environment. On the 5th, 10th, 20th, and 30th day, the excretion of uric acid in rats was detected by a biochemical analyzer, the level of desmin protein in rat podocytes was detected by immunohistochemistry, and the activity of Na+-K+- ATPase in rat proximal tubular epithelial cells was measured by liquid scintillation method. The results showed that with the increased time, the level of uric acid in the blood of rats in the test group increased dramatically (P<0.05). On the 30th day, the blood uric acid content of the test group was 52.33μmol/L, and that of the control group was 38.43μmol/L. The blood uric acid content in the test group was dramatically increased relative to the control group. Immunohistochemistry showed that the desmin protein in podocytes of the test group (0.14) was considerably higher than that in the control group (P<0.05). The Na+-K+- ATPase activity of proximal renal tubular epithelial cells in the test group was 611.2 pmol pi/mg protein/h, which was considerably lower than the versus control group (P<0.05). In summary, in high altitude hypoxia environment, uric acid accumulated in the body, and renal filtration and excretion ability was limited.

A Study on the Relationship Between Adolescent Health Behavior, BMI, and Blood Physical and Chemical Properties.

In this study, the blood test index, demographic data, and health promotion behavior of adolescents were analyzed to provide a reference for early prevention and treatment of physical decline and abnormal biochemical indexes of adolescents. Using a cross-sectional study design, 1,436 valid samples were obtained by stratified random sampling, and the data were processed by SPSS21.0 statistical analysis software. The results showed that the overall health-promoting lifestyle of adolescents was good, and the interpersonal support behavior was the best, and the health responsibility and sports participation behavior were the worst; the interpersonal support and sports participation behavior of adolescents with normal weight were significantly better than those with overweight or light weight, while the overall health-promoting behavior of adolescents with high fasting blood glucose (FBG) before meals was poor, those with high glutamate pyruvate transaminase (GPT) had poor nutritional behavior and health responsibility behavior, while those with high uric acid (UA) had poor interpersonal support and stress coping behavior. The overweight rate and abnormal detection rate of UA and triglyceride (TG) in boys were significantly higher than those in girls, and the higher BMI of teenagers, the higher abnormal detection rate of GPT, UA, and TG, the better nutritional behavior, health responsibility behavior, and sports participation behavior, the lower abnormal detection rate of GPT, UA, and TG; the higher education level of parents, the better teenagers' sports participation and health responsibility behavior, the lower the incidence of overweight, the more time they spend playing online games and drinking sugary drinks on weekdays (or holidays), the higher the incidence of overweight.

Use of haematological signatures in conjunction with conventional biomarkers to assess Reno-protective effects of Gedunin in diabetic nephropathy of Streptozotocin induced diabetic rats.

The present study was aimed at analysing the reno-protective potential of Gedunin (a limonoid from Neem leaves) through haematological and serological assays and renal histopathology studies in streptozotocin induced diabetic rats. Four weeks old Wister albino rats were chosen for the study. The rats were divided into four groups of 8 rats each. Group 1 (normal control rats); Group 2 (diabetic control rats); Group 3 (Drug control rats: normal rats treated with 1mg/kg body weight of Gedunin thrice a week through oral gavage for 2weeks); Group 4 (diabetic rats treated with Gedunin similar to Group 3). Diabetes was induced using a single intraperitoneal injection of streptozotocin (50mg/kg) in the pre-determined groups. After completion of treatment, the rats were sacrificed and haematological and serological parameters including functional indices of blood cells and renal markers were evaluated through spectrophotometric methods. Renal histology studies were carried out and images were captured on Olympus SC 100, 10 Mega Pixel camera. Streptozotocin induced diabetes lead to marked reduction in the RBC count, haemoglobin, PCV, WBC count, lymphocyte, elevated levels of fasting blood glucose, kidney function markers such as urea, creatinine, uric acid in rats. Administration of Gedunin significantly (P < 0.05) ameliorated the elevated levels of fasting glucose, RDW%, MCHC%, NLR% and platelet count. A significant reversal of renal tissue damage was also observed. The restoration of renal serological markers and reversal of renal tissue injuries are all indicative of promising reno-protective potential of Gedunin. Remarkable improvement of haematological parameters supports their use as reno-protection markers.

Hashimoto's thyroiditis is associated with elevated serum uric acid to high density lipoprotein-cholesterol ratio.

Background. Hashimoto's thyroiditis (HT) is an auto-immune condition characterized with lymphocytic and fibroblastic infiltration of the thyroid gland. The rate of uric acid and HDL cholesterol - so called as uric acid to HDL ratio (UHR) has been shown to be elevated in inflammatory conditions diseases. We aimed to compare UHR and other laboratory parameters of the patients with HT to those values in healthy controls. Methods. The patients diagnosed with HT by medical history, physical examination, elevated thyroid autoantibodies in serum and characteristic sonographic findings in outpatient internal medicine clinics of our institution were enrolled to the present retrospective study. Age and sex matched healthy volunteers were enrolled as controls. UHR of the HT patients and control subjects were compared. Results. The mean UHR of the HT group was 11% ± 4 %, while UHR of the control group was 8% ± 2% (p<0.001). UHR was significantly and positively correlated with thyroid stimulating hormone (TSH) (r=0.26, p=0.01) and negatively correlated with free T4 (FT4) (r=-0.22, p=0.04) levels. The sensitivity and specificity of the UHR level were greater than 8.3%: were 74% and 52%, respectively (AUC: 0.74, p<0.001, 95% CI: 0.64-0.84). Conclusion. We suggest that UHR is a reliable and useful marker for HT. Therefore, it may be helpful in establishing the diagnosis of HT in addition to other diagnostic tools.

Stone composition of renal stone formers from different global regions.

To study urinary stone composition patterns in different populations around the world. Data were collected by reviewing charts of 1204 adult patients of 10 countries with renal or ureteral stones (> 18 years) in whom a stone analysis was done and available. Any method of stone analysis was accepted, but the methodology had to be registered. In total, we observed 710 (59%) patients with calcium oxalate, 31 (1%) with calcium phosphate, 161 (13%) with mixed calcium oxalate/calcium phosphate, 15 (1%) with carbapatite, 110 (9%) with uric acid, 7 (< 1%) with urate (ammonium or sodium), 100 (9%) with mixed with uric acid/ calcium oxalate, 56 (5%) with struvite and 14 (1%) with cystine stones. Calciumcontaining stones were the most common in all countries ranging from 43 to 91%. Oxalate stones were more common than phosphate or mixed phosphate/oxalate stones in most countries except Egypt and India. The rate of uric acid containing stones ranged from 4 to 34%, being higher in Egypt, India, Pakistan, Iraq, Poland and Bulgaria. Struvite stones occurred in less than 5% in all countries except India (23%) and Pakistan (16%). Cystine stones occurred in 1% of cases. The frequency of different types of urinary stones varies from country to country. Calcium-containing stones are prevalent in all countries. The frequency of uric acid containing stones seems to depend mainly on climatic factors, being higher in countries with desert or tropical climates. Dietary patterns can also lead to an increase in the frequency of uric acid containing stones in association with high obesity rates. Struvite stones are decreasing in most countries due to improved health conditions.

Структурно-функциональное состояние костной ткани, гиперурикемия и компоненты метаболического синдрома у женщин в постменопаузальном периоде

В статье представлены результаты исследований по изучению уровня мочевой кислоты у женщин в постменопаузальном периоде с учетом показателей индекса массы тела, липидного обмена и минеральной плотности костной ткани. Самый высокий уровень мочевой кислоты в сыворотке плазмы крови выявлен у женщин в постменопаузальном периоде с наибольшим индексом массы тела (ИМТ &gt; 35 усл.ед.). У женщин в постменопаузальном периоде существует достоверная зависимость между уровнем мочевой кислоты и показателями липопротеидов очень низкой плотности (r = 0,401, p &lt; 0,05), триглицеридами (r = 0,26, p &lt; 0,05), коэффициентом атерогенности (r = 0,24, p &lt; 0,05). Частота остеопороза была ниже в группе пациенток с гиперурикемией по сравнению с лицами с нормоурикемией. Так, в группе пациентов с гиперурикемией она составляла 19 %, а у пациентов с нормоурикемией — 34 % на уровне поясничного отдела позвоночника, 17 и 21 % — на уровне шейки бедренной кости соответственно.

Electrolytic drinking water improves the metabolism of uric acid in the SD rats with hyperuricemia

To investigate the effects of electrolytic drinking water on the hyperuricemia and the potential mechanism. The 6-week-old SD rats were induced as the animal model with hyperuricemia by yeast extract(10 g/kg) and adenine(100 g/kg) gavage(twice per day) combined with oxygen oxazine acid potassium(300 mg/kg, the 1~(st), 5~(th) and 10~(th )day) i. p. Then the rats were supplied electrolytic drinking water in different dosages(1 mL, 2 mL and 3 mL) by gavage for 7 days. Weight was measured at regular intervals. The 24-hour urine was sampled by metabolic cage for the measurements of uric acid, creatinine and urea nitrogen levels. The parameters for the uric acid clearance were calculated. The serum was sampled after execution for the determination of serum uric acid, creatinine. The activities of xanthine oxidase and adenine dehydrogenase were detected. The morphological measurements of stomach and kidney were completed. The hyperuricemia model was successfully induced by this method. In the intervention, the pH of urine was significantly elevated along with the electrolytic drinking water intake(P&lt;0. 01). The excretion of uric acid in the rats with hyperuricemia was significantly increased while administrated with electrolytic drinking water. The effects of improving uric acid excretion were enhanced along with the intake of electrolytic drinking water. The levels of serum uric acid(group Model, Model+Treatment 1, Model+Treatment 2 and Model+Treatment 3: 693. 7 μmol/L, 668. 1 μmol/L, 642. 5 μmol/L, 633. 1 μmol/L), urine uric acid(5740. 0 μmol/L, 5894. 1 μmol/L, 5562. 3 μmol/L, 5083. 2 μmol/L) and urea nitrogen(11. 40 mmol/L, 10. 47 mmol/L, 9. 54 mmol/L, 8. 93 mmol/L) were significantly decreased in the model rats with high dose intervention(P&lt;0. 05). Clearance of uric acid was obviously increased(9. 27%, 10. 40%, 10. 44%, 11. 13%, P&lt;0. 05). However, no pathological change was observed among the three groups with intervention. The electrolytic drinking water intake is benefit for the excretion of uric acid of hyperuricemia rat. Enhancing alkalization of urine is considered as the important mechanism of the beneficial effects.

Endothelin Level and Its Correlation with Uric Acid in Type 2 Diabetic Multiuse Patients

This research aims to find the direct linkage among the Uric acid rates with Endothelin (ET-1), which is considered the indication of endothelial dysfunction or endothelial damage in patients with T2-DM. This study, included 96 patients with T2-DM and 96 controls, the mean age ranged (56.73 ± 9.14), (56.42 ± 8.74) respectively. Results showed a highly significant increase in Endothelin (ET-1) levels, uric acid, urea, and systolic blood pressure (SBP) was observed as compared with the control group, while Diastolic blood pressure (DBP) and body mass (BMI) were not substantially increased. Additionally, a significant positive correlation was found between ET-1 with uric acid, urea, SBP, DBP in patients with T2-DM (p &lt; 0.05). Finally, elevated uric acid levels in older people who have chronic blood pressure are one of the factors influencing the increased release of ET-1, thus the development of cardiovascular disease.

Acute emotional stress and high fat/high fructose diet modulate brain oxidative damage through NrF2 and uric acid in rats

Studies focusing on the interaction of dietary and acute emotional stress on oxidative stress in cortex frontal and in brain mitochondria are scarce. Dietary-induced insulin resistance, as observed in Western diets, has been associated with increased oxidative stress causing mitochondrial dysfunction. We hypothesized that acute emotional stress could be an aggravating factor by impacting redox status in cortex and brain mitochondria. Thus, the aim of the present study was to evaluate the combination of an insulin resistance inducing high-fat/high-fructose (HF/HFr) diet and acute emotional stress on brain oxidative stress in rats. We measured several oxidative stress parameters (carbonyls, FRAP, TBARS assays, GSH, GSSG, oxidized DNA, mRNA expression of redox proteins (Nrf2), and uric acid). The HF/HFr diet resulted in increased oxidative stress both in the brain mitochondria and in the frontal cortex and decreased expression of the Nrf2 gene. The emotional stress induced an oxidative response in plasma and in brain mitochondria of the control group. In the HF/HFr group it triggered an increase expression of the redox transcription factor Nrf2 and its downstream antioxidant genes. This suggests an improvement of the redox stress tolerance in response to an enhanced production of reactive oxygen species. Accordingly, a blunted oxidative effect on several markers was observed in plasma and brain of HF/HFr-stressed group. This was confirmed in a parallel study using lipopolysaccharide as a stress model. Beside the Nrf2 increase, the stress induced a stronger UA release in HF/HFr which could take a part in the redox stress.

Beneficial Effects of Macroporous Resin Extract of Dendrobium candidum Leaves in Rats with Hyperuricemia Induced by a High‐Purine Diet

Objectives. The incidence of hyperuricemia (HUA) is increasing year by year, and there are no ideal drugs for the treatment; the existing ones can cause serious liver and kidney damage. We have confirmed that the water extract of Dendrobium candidum leaves could reduce the level of uric acid in rats, but the active ingredients remain unknown, and the mechanism is not well understood. This research investigated the therapeutic effect of the macroporous resin extract of the Dendrobium candidum leaf (DLE) on hyperuricemia. In this study, hyperuricemia was induced in rats by a 5-week high-purine diet. After that, DLE was administered continuously for 9 weeks. The result showed that biochemical parameters of liver and kidney function, especially serum uric acid (UA) levels, were significantly improved with DLE, which may relate to the reduction of xanthine oxidase (XOD) and adenosine deaminase (ADA) in the liver. Moreover, DLE could significantly prevent kidney and liver from damage, and intestinal injury and reduce inflammation in hyperuricemic rats by inhibiting the expression of both NF-κB and TLR4 proteins. These results showed that the macroporous resin extract of the Dendrobium candidum leaves may be effective for the treatment of hyperuricemia in rats by inhibiting uric acid production and decreasing inflammation.

Efek Pemberian Ekstrak Etanol Daun Leilem (Clerodendrum minahasae) terhadap Kadar Kreatinin, Asam Urat dan Ureum pada Tikus Putih (Rattus novergicus)

The progress of science in the field of medicine is currently very rapid along with technological advances, but the use of traditional medicines is increasingly popular. This is due to the low side effects caused by traditional medicines, practical use, easy to obtain and affordable prices. North Sulawesi is one area that has so many types of plants, including leilem plants (Clerodendrum minahassae) of the genus Clerodendrum. Leilem plant is an endemic plant in North Sulawesi which is often consumed by vegetables as a vegetable and is usually added to meat processing. This study aims to determine the effect of ethanol extracts of leilem leaves on the description of urea, uric acid and creatinine values ​​in etylen glycol induced white rats. The study design, the treatment group was divided into 5 groups. The control group (P0), the ethylene glycol group (P1), the rockgin treatment group (P2), the ethanol extract group of leilem leaves at a dose of 150 mg / kgBB (P3), and the ethanol extract group of leilem leaves at a dose of 300 mg / kgBB (P4). The results showed that the ethanol extract of leilem leaves 150 mg / kgBB and 300 mg / kgBB could reduce the levels of ureum, creatinine and uric acid in rats with ethylene glycol treatment. Ethanol extract of leilem leaves 150 mg / kgBB was better in reducing levels of urea, creatinine and uric acid in rats compared with a dose of 300 mg / kgBB (p &lt;0.05)

P5413Effect of empagliflozin as add-on therapy on serum uric acid level in patients with type 2 diabetes hospitalized for acute decompensated heart failure: a prospective randomized controlled study

Abstract Background Elevated serum uric acid (UA) level has been shown to be associated with reduced survival among patients (pts) with heart failure. Sodium glucose cotransporter 2 (SGLT2) inhibitors have been reported to lower serum uric acid level in pts with type 2 diabetes mellitus (T2D). Empagliflozin, one of the SGLT2 inhibitors, has been shown to reduce the risk of cardiovascular mortality in T2D pts with cardiovascular disease, and involvement of UA lowering effect by empagliflozin in the reduction of cardiovascular mortality has been suggested. However, little is known about the effect of empagliflozin as add-on therapy on serum UA level in T2D pts with acute decompensated heart failure (ADHF). Purpose We sought to elucidate the effect of empagliflozin as add-on therapy on serum UA level in T2D pts with ADHF. Methods We enrolled 38 consecutive T2D pts admitted for ADHF. On admission, enrolled pts were randomly assigned in a 1:1 ratio to either empagliflozin add-on therapy (EMPA(+)) or conventional glucose-lowering therapy (EMPA(−)). All pts in EMPA(+) group received empagliflozin (10 mg/day) throughout the study period. Left ventricular ejection fraction (LVEF) was measured at baseline using echocardiography. Body weight and vital signs, such as blood pressure and heart rate, were measured, and blood and urine samples were collected at baseline and 1, 2, 3 and 7 days after randomization. Renal handling of UA was evaluated by fractional excretion of UA (FEUA). Results Twenty pts were assigned to the EMPA(+) group, and 18 pts were assigned to the EMPA(−) group. There were no significant baseline differences in LVEF, plasma brain natriuretic peptide level, body mass index, or serum creatinine level between the EMPA(+) and EMPA(−) groups. In addition, prevalence rate of hyperuricemia, serum UA level, and FEUA did not significantly differ between the two groups at baseline. However, there was significant difference in the change in serum UA level from baseline at 2, 3 and 7 days after randomization between the two groups (Figure A). As a result, serum UA level was significantly lower in the EMPA(+) group than in the EMPA(−) group at 7 days after randomization (6.2±1.8 mg/dL vs 7.8±1.8 mg/dL, p=0.0127). Moreover, FEUN of the EMPA(+) group was significantly higher at 1, 2 and 7 days after randomization (Figure B), which suggested that serum UA level was lowered in the EMPA(+) group by increased urinary excretion of UA. Figure 1 Conclusions This study demonstrated that empagliflozin as add-on therapy can lower serum UA level in T2D pts with ADHF through the effect on the urinary excretion rate of UA.

The Effect of Ethanol Extract of Elephantopus scaber Linn in Decreasing Blood Uric Acid Levels of Hyperuricemic Male Rats

Background: Gout causes attacks of pain and swelling in one or more joints and control of serum uric acid level has been used as one of the therapeutic methods for gout. Inhibition method of xanthine oxidase (XO) activity which can oxidize hypoxanthine to uric acid has been commonly used to decrease serum uric acid level. On the other hand, Elephantopus scaber Linn leaf has been used for the treatment of rheumatoid arthritis as folk medicine by some people in Indonesia.&#x0D; Aims: This study was to determine the hypouricemic effect of ethanol extract of Elephantopus scaber leaf by in vivo study in caffeine (PO)-induced hyperuricemic male rats.&#x0D; Methodology: The E. scaber leaf was obtained from Research Institute for Spices and Medicinal Plants, Bagor, Indonesia. Preparation of E. scaber leaf extract was done by cold maceration extraction technique using ethanol 70%. Male rats (Sprague-Dawley) were induced by using caffeine with dose 27 mg/200 g b.w until the levels in the blood of male rats become hyperuricemic. Equipment (Easy Touch) was used by detecting the level of uric acid in a rat blood. Equipment (Easy Touch) was used by detecting the level of uric acid in a rat blood.

Statistical analysis on the 15th day showed that all of the test preparation groups of E. scaber had effects decrease uric acid in blood serum of rats and significantly different from negative controls (p ≤ 0.05). The dose of 350 mg/200 g b.w of E. scaber had the same effect with a dose of 36 mg/200 g b.w allopurinol in reducing uric acid in experimental rats.&#x0D; Conclusions: E. scaber is a plant that is quite potential to be used in the treatment of gout.

Study the protective effect of Matricaria chamomilla flower extract against the toxicity of Entamoeba histolytica induces liver and renal dysfunctions in adult albino male rats

The present study was designed to show the potential role of Matricaria chamomilla flower extract against toxicity of Entamoeba histolytica . The study used 20 adult albino male rats that divide randomly to four groups (each group consist 5 rats); control group received ad libidium, group of rats administrated with 1X103 cyct/ml suspension for seven days, group of rats administrated with 1X103 cyct/ml suspension and treated with 50mg/kg extract for month, group of rats administrated with 1X103 cyct/ml suspension and treated with 100mg/kg extract for month. The results show high significant increased (P < 0.05) in levels of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Alkaline Phosphatase (ALP), urea, creatinine and uric acid in rats administrated with 1X103 cyct/ml suspension. Oxidative stress factor in this group show significant increased (P < 0.05) in levels of MDA (malonedialdehyied) and significant decreased (P < 0.05) in levels of glutathione (GSH) and catalase compared with control group. While, after used M. chamomilla flower extract with Entamoeba histolytica , the results showed non significant changes (P < 0.05) in liver and kidneys function parameters. Also, MDA, GSH and catalase showed non significant changes (P < 0.05) compared with control group. It was concluded that flower extract has been potential role against toxicity of Entamoeba histolytica in adult male albino rats.
