Triton Wr 1339

Hypercholesterolemia is a chief risk reason for atherosclerosis. Triton-WR 1339 (Tyloxapol) was used by several investigators to initiate hypercholesterolemia in animals. Housefly maggots contain high larval protein extract (PE) that is used as an anti-atherosclerosis. The goal of the current study was to evaluate the possible protective effects of the PE of houseflies against Triton-WR 1339-induced hyperlipidemia, oxidative damage, and histopathological changes of the liver and dorsal aorta of male mice. In this study, four groups of experimental mice, including ten mice each, were classified into: Group I, mice were administered with 0.5 ml saline solution, and considered as a positive control; Group II, mice were administered day after day by gavage with 0.5 ml of 200 mg/kg bw PE; Group III, hyperlipidemic mice were taken no treatment till the end of experiment and Group IV, the hyperlipidemic mice were administered day after day by gavage with 200 mg/kg bw PE. On day 40, the mice were anesthetized, blood samples were collected, the livers and the aorta were dissected for various biochemical tests and histopathological examinations. The biochemical parameters, triglycerides (TGs), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C) and lipid peroxidation (LPO) were increased, and reduction in high-density lipoprotein-cholesterol (HDL-C), the total glutathione (GSH) and the glutathione peroxidase (GPx) levels were observed following Triton WR-1339 treatment in mice. After administration of the PE (200 mg/kg bw), the results revealed significant reduction in serum TC and TGs while HDL-C, oxidative stress levels in liver tissue, LPO, GSH and GPx were significantly increased. Histopathological examinations of the liver tissue and the aorta of mice showed alterations afterwards Triton WR-1339 administration. Treatment with 200 mg/kg bw PE showed beneficial effects with lower capsular thickening, enlargment of hepatocytes and much lower inflammatory cell infiltration.

Abstract Background Obesity is associated with insulin resistance, type2 diabetes, dyslipidemia and cardiovascular diseases. Apelin and chemerin are identified as adipokines and adipose tissue markers. Several adipose-derived peptides are known to influence food intake, including apelin, whose expression is regulated by insulin and chemerin. Oxidative stress thought to be involved in the development of complications associated with obesity. Objective To study the nature of correlation between serum and liver levels of apelin, chemerin and oxidative parameters in obese rats with and without antioxidant. Aiming to clarify the pathophysiology of obesity. Material and Methods Thirty adult male albino rats, divided into three equal groups. Group I (control), group II (obese) and group III (obese and Lepidium sativum (LS) as an antioxidants). At the end of the experiment, blood samples were collected for estimation of the serum levels of chemerin, apelin, fasting glucose, insulin, insulin resistance (IR), lipid profile, reduced glutathione (GSH) and malondialdehyde (MDA). In addition to tissue homogenous extracts of liver were taken for the levels of MDA, CAT, chemerin and apelin. Results After eight weeks, high fat diet group showed a significant increase in serum levels of apelin, chemerin, fasting glucose, insulin, IR, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) & MDA and a significant decrease in high-density lipoprotein cholesterol (HDL-C) & GSH. HFD also caused a significant increase in tissue levels of MDA, CAT & chemerin and a significant decrease in apelin, compared to control group. While addition of LS to HFD caused a significant decrease in serum levels of apelin, chemerin, fasting glucose, insulin, IR, TC, TG, LDL-C & MDA and a significant increase in HDL-C & GSH. LS also caused a significant decrease in tissue levels of MDA, chemerin & insignificant decrease in CAT and a significant increase in apelin, compared to HFD group. Conclusion This study showed a significant positive correlation between liver & serum chemerin and between liver and serum MDA. On the other hand, it showed a significant negative correlation between liver and serum apelin and liver CAT and serum GSH

BACKGROUND: Diabetes mellitus is a common disease worldwide which affects renal function. Cardiovascular morbidity and mortality in diabetes patients can be accelerated by dyslipidemia. Small dense lowdensity lipoprotein-cholesterol (sdLDL-C) is atherogenic and its predominance has been known as a cardiovascular risk factor. The study aimed to assess the validity of calculated sdLDL-C using three different formulae and its association with other clinical variables in diabetic patients with and without nephropathy, and also to determine the best suited formula to measure sdLDL-C.METHODS: The study subjects were divided into two groups based on the amount of albumin excreted in the urine. Group I or the control group consisted of diabetic subjects without microalbuminuria, while group II consisted of diabetic subjects with microalbuminuria. Blood glucose, glycated haemoglobin (HbA1c), creatinine, total cholesterol (TC), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), LDL-C and apoB were estimated. Three formulae used for the validation of calculated sdLDL-C were TG/HDL, sdLDL (mg/dL) = 0.580 (nonHDL) + 0.407 (direct-LDL-C) – 0.719 (calculated-LDL-C) – 12.05, and LDL-C/LDL apoB.RESULTS: There was no significant difference in sdLDL-C levels of diabetic subjects with and without nephropathy. The sdLDL-C had strong correlation with TC, TG, LDL-C, very-low-density lipoprotein (VLDL), non-HDL and apoB in both study groups. ROC curve showed that LDL-C/LDL apoB derived sdLDL-C had better sensitivity (85%) and specificity (69%) compared to other two measures.CONCLUSION: Though the calculated sdLDL-C do not predict the occurrence of nephropathy in diabetes subjects, it may still be used in conjunction with the traditional markers since it is cost effective. The LDL-C/LDL apoB formula is the best predictor of sdLDL-C among the three equations.KEYWORDS: HDL-C, LDL-C, Microalbuminuria, sdLDL-C, T2DM

Objective: To investigate the effect of antibiotics and/or probiotics on broiler performance, some serum metabolites, cecum microflora composition, and ileum histomorphology under the Egyptian conditions. Design: Randomized controlled experimental study. Animals: Two hundred forty 1-day-old Ross (308) chicks were reared till 35 days of age. Procedures: The birds were randomly allocated into four main groups: a control diet without additives (CON); probiotic (Lactobacillus acidophilus) supplemented diet (PRO); antibiotic (Avilamycin) supplemented diet (ANT) and a mix group (AP) that received antibiotic in the diet form 1 to 4 days of age and treated during the rest of the experimental period with probiotics. Results: Chickens fed on probiotic or antibiotic diets had linear improvement in live body weight (LBW) and feed conversion ratio (FCR) compared with the control group, while the best LBW and FCR were in the AP group. An improvement in the nutrient digestibility was observed in the probiotic added groups (PRO and AP). Serum cholesterol and low-density lipoprotein cholesterol contents decreased when antimicrobial (probiotic or antibiotic) supplementations were used, while there was an increase in high-density lipoprotein cholesterol contents, serum total protein, and albumin levels. Among all groups, cecum Clostridium perfringens and Escherichia coli counts decreased; however, there was an increase in Lactobacillus count compared to the control group. In probiotic supplemented groups (PRO and AP), a significant (P<0.05) improvement in ilea architecture. Conclusion and clinical relevance: Using probiotic after initial treatment with an antibiotic in broiler diets had a positive effect on broiler growth performance, gut health (improved cecum microbial populations and ileum histomorphology), and nutrient digestibility.

Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.

Objective: Hyperlipidemia is one of the risk factors that contribute to the prevalence of coronary heart diseases and antihyperlipidemic agents, such as statin, was used to treat hyperlipidemia as a current therapy. Boesenbergia pandurata has not been exploited for antihyperlipidemic effect. Hence, this study aims to screen for the antihyperlipidemic activity of methanolic extracts of B. pandurata rhizomes (BPR extracts) in hypercholesterolemia-induced Sprague-Dawley rats.Methods: BPR extracts were prepared using the maceration method with 1500 ml of 80% methanol at room temperature for about 7 days. A toxicity study was carried out based on OECD guidelines. Hypercholesterolemia was induced by 6% lard oil, 2% of cheese, and egg yolks. Two different doses of BPR extracts, 200 and 400 mg/kg, were used to screen for antihyperlipidemic effect. Histopathological study was carried out in the liver. The results were evaluated for the statistically significant difference by using the one-way ANOVA followed by post hoc Dunnett test.Results: No mortality was witnessed even till 2 g/kg. Only 400 mg/kg of BPR extracts statistically reduced in total cholesterol (p<0.05), low-density lipoprotein-cholesterol (p<0.05) and an increase in high-density lipoprotein-cholesterol (p<0.05) when compared to the positive control. BPR extracts (400 mg/kg) showed less enlargement of lipid droplets as compared to positive control.Conclusion: BPR extracts can be a promising medicinal plant for treating hyperlipidemia in underdeveloped countries.

OBJECTIVE: The present study aimed to evaluate the effect of feeding diets enriched with fatty fish from the Amazon basin on lipid metabolism. METHODS: Male Wistar rats were divided into four groups: control group treated with commercial chow; Mapará group was fed diet enriched with Hypophthalmus edentatus; Matrinxã group was fed diet enriched with Brycon spp.; and, Tambaqui group was fed diet enriched with Colossoma macropomum. Rats with approximately 240g±0.60 of body weight were fed ad libitum for 30 days, and then were sacrificed for collection of whole blood and tissues. RESULTS: The groups treated with enriched diets showed a significant reduction in body mass and lipogenesis in the epididymal and retroperitoneal adipose tissues and carcass when compared with the control group. However, lipogenesis in the liver showed an increase in Matrinxã group compared with the others groups. The levels of serum triglycerides in the treated groups with Amazonian fish were significantly lower than those of the control group. Moreover, total cholesterol concentration only decreased in the group Matrinxã. High Density Lipoprotein cholesterol levels increased significantly in the Mapará and Tambaqui compared with control group and Matrinxã group. The insulin and leptin levels increased significantly in all treatment groups. CONCLUSION: This study demonstrated that diets enriched with fatty fish from the Amazon basin changed the lipid metabolism by reducing serum triglycerides and increasing high density lipoprotein-cholesterol in rats fed with diets enriched with Mapará, Matrinxã, and Tambaqui.

Diabetes mellitus (DM) is a serious chronic metabolic disorder. Various diseases are being treated with medicinal plants and that is because of the less side effects of the current therapy. The diversity of plants in Armenia is due to the singularity of natural environment. However, biochemical activity of these plants has not been studied well. Thus, the goal was to investigate biochemical activity and antihyperglycemic properties ofRumex obtusifoliusL. in rabbits with hyperglycemia. The high content of total phenolic compounds, flavonoids, and tannins has been determined in this plant extract. Oral administration of ethanol extract showed significant effect on hyperglycemia, reducing fasting glucose levels (57.3%, p<0.05), improving glucose tolerance, and increasing liver glycogen content (1.5-fold, p<0.01) compared to the hyperglycemic control group. Furthermore, ethanol extract ofR. obtusifoliusreduced total cholesterol, low-density lipoprotein cholesterol levels, and vice versa increased high-density lipoprotein cholesterol levels and also decreased liver enzymes levels (alanine aminotransferase and aspartate aminotransferase) compared with untreated group. These findings suggest thatR. obtusifoliusmay have beneficial effects and should be supplement, as herbal remedy in the treatment of DM.

  The niacin in energy drinks has metabolic product that cause oxidative stress and liver damage, while the liver damage can be prevented by hepatoprotective agents. Scoparone in Artemisia vulgaris L. can act as a hepatoprotector by its antioxidant effect. This study aimed to investigate the effectivity of Artemisia vulgaris L. extract as a hepatoprotector in wistar hepatocytes induced by niacin. This study used 25 male rats which were divided into 5 groups: normal, the negative control, the positive control, the treatment group I, and II. Treatment was conducted for 28 days. The samples were terminated and the hepatocyte were prepared for histological examination. Histological appearance was catagorized as mild, moderate, and severe damage with or without inflamatory cells activity. The data analysis by Kruskal Wallis showed significant difference (p<0,001). Further analysis by Mann Whitney revealed significantly difference (p<0,05) between normal group and all groups, negative control group and positive control group, and positive control group and treatment group I, but not significantly difference between negative control group and treatment group I, negative control group and treatment group II, positive control group and treatment group II, and between treatment groups. The study concluded that the effectivity of Artemisia vulgaris L. extract has not been proven as a hepatoprotector but further study is needed to draw a definite conclusion.   Keywords: energy drink, niacin, Artemisia vulgaris L., hepatoprotector

The metabolic fitness (MF) is a component of athletes’ physical conditioning. This study aims to investigate the effects of quercetin supplementation on Turkish Junior athletes’ lipid and protein metabolism relating to MF after one month classic boxing training. Totally 20 voluntary junior male athletes were separated into two equal groups as the experimental group (EG) and control group (CG). The participants were supplemented with 500 mg quercetin fifteen minutes before each workout in one month boxing training program. Blood samples during pre and post training were taken from athletes in order to determine metabolic fitness related parameters. Lipid profile contains low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), trigliserid (TG), total cholesterol (TC) variables while protein metabolism includes the albumin, total protein, direct bilirubin and total bilirubin parameters. The Mann Whitney U analyzes were used for comparison of the means between experimental and control groups during pre and posttest and between pre and post test results in experimental and control groups. This study showed that EG had a similar physical characteristic with CG. There were significant decrease in TC and LDL-C and an increase in HDL-C in EG while there was only significant increase in HDL-C of in controls. A significant difference of HDL-C was observed between EG and CG during pretest. In other side, TC and LDL-C and HDL-C were significantly differentiated between EG and CG during posttest. Conclusion: it can be concluded that quercetin plays an important role on lipid metabolism not protein.
