O presente estudo teve como objetivo avaliar as repercussões bioquímicas em ratos Wistar submetidos ao jejum intermitente por 15, 30 e 60 dias, modelo de dieta intercalada por períodos de restrição total de alimentação com períodos de alimentação ad libitum. O estudo foi realizado com 40 ratos Wistar, machos divididos em três grupos, todos recebendo a ração Nuvital®. Os ratos submetidos ao jejum intermitente tiveram esse tipo de dieta durante 3 dias na semana e nos demais dias tiveram acesso livre a ração e água. Os animais foram pesados semanalmente e, após o período de jejum intermitente, foram eutanasiados para a coleta de sangue e análise bioquímica (glicemia, triglicérides, colesterol total e frações). Houve redução significativa do peso e triglicerídeos nos animais do grupo de jejum em relação ao grupo controle durante 15 dias. Em relação ao grupo de 30 dias de jejum, houve redução significativa de colesterol total e HDL. Nos animais submetidos à dieta durante 60 dias, houve diminuição significativa de colesterol total e HDL, no entanto, o consumo de água aumentou consideravelmente. Conclui-se  que o jejum intermitente durante 15 dias causou alterações bioquímicas favoráveis ao metabolismo desses animais. Palavras-chave: Jejum Intermitente. Restrição Calórica. Prevenção. AbstractThis experiment was conducted to evaluate the biochemical effects in healthy Wistar rats submitted by 15, 30 and 60 days to intermittent fasting, a model of interspersed diet between periods of total food restriction withfood ad libitum period. The study was performed with 40 male Wistar rats randomly divided into 3 groups, all receiving Nuvital®. The rats submitted to intermittent fasting had this type of diet during 3 days a week and on the other days had free access to food. They received water ad libitum every day. The analysis related to metabolic changes resulting from fasting were performed by means of serum biochemical analysis (blood glucose, triglycerides, total cholesterol and HDL) at the end of the experiment. There was a significant reduction of weight and triglycerides from the fasting group in relation to the control group in 15 days, there was no significant increase in parameters during this period of diet. Concerning the 30-day fasting  group, there was a significant reduction of total cholesterol and HDL. Therefore, Intermittent Fasting in 15 days only demonstrated biochemical benefits. Keywords: Intermittent Fasting. Caloric restriction. Prevention.

The purpose of this study was to prove that the administration of Jati (Guazuma ulmifolia Lamk) leaves extract improves the lipid profile of dyslipidemic male Wistar rats. Subjects were 20 rats (Rattus norvegicus), male, Wistar strain, dyslipidemia (total cholesterol ≥ 200 mg dl-1), aged 2 months old, weighing 180-200 grams. The control group (10 rats) were given a placebo of 3 ml aquadest (P0) and the treatment group was given extracts of the Jati (Guazuma ulmifolia Lamk) leaves extract of 25 mg kg-1 BW (P1). Before and after treatment for 14 days, total cholesterol, triglyceride, LDL, and HDL levels were examined. The results showed that in the P0 group there were no changes in total cholesterol, triglyceride, LDL, and HDL levels (p>0.05), whereas the P1 group experienced a decrease in total cholesterol, triglyceride and LDL levels (p<0.05) and an increase in HDL levels (p<0.05). The results of this study indicated that the Jati leaves extract was effective to improve the lipid profile of dyslipidemic rats. It was necessary to compare the effectiveness of Jati leaves extract with synthetic dyslipidemia drugs used in the community such as statin.

Ad Libitum Feeding

AbstractMale Wistar rats were deprived of food for 3 days and then forced to swim continuously to a criterion of exhaustion. Controls swam after ad libitum feeding. In the first experiment a load equal to 11% of the rat's body weight was attached to the dorsal skin near the tail during the swim. In a second study, two matched groups, treated identically as those in the first study swam without a load in water treated with a wetting agent, "Aerosol O.T." In a third experiment, controls as well as experimentals were deprived of food for three days. The control group, however, was fed for 30 minutes, immediately before the swim. A fourth experiment was conducted in a similar manner as the third, except both groups were deprived 6 hours. In each of the experiments the deprived groups swam significantly longer than the fed groups.

Different Doses

Tartrazine is one of the most widely used artificial foods, drugs and cosmetic dyes. It is a nitrous derivative and is known to cause allergic reactions such as asthma and urticaria, as well as having been the focus of studies on mutagenesis and carcinogenesis due to its transformation into aromatic amine sulfanilic acid after being metabolized by the gastrointestinal microflora. 45 male Wistar rats were assigned to a control group (A) or a treatment one (B). The treatment group received 7.5 mg.kg-1.day-1 of tartrazine daily in drinking water offered ad libitum for ten months from weaning to the age of twelve months. There was a significant increase in the number of lymphocytes and eosinophils of the gastric antrum mucosa. No carcinogenetic changes in any gastric area were observed during the study. As tartrazine belongs to the azo class, it is still a possible food carcinogen. Other studies with different doses and schedules, observing their effects associated to other carcinogens should be carried out if their safe use is to be recommended.

<p>Changes in diet, physical inactivity and stress contribute to obesity, cardiovascular disease and atherosclerosis. Literature shows that bioactive compounds may result in benefits to human health. The aim of this study was to evaluate the glycemic, lipid profile and atherogenic indices of Wistar rats treated with <em>Mentha piperita</em> and <em>Tamarindus indica</em> juice. Animals received food and water <em>ad libitum </em>and were divided into 3 groups: control group (G1) that received 0.5 mL of water twice daily; <em>Mentha </em>group (G2) treated with 0.5 mL of mint juice and group treated with <em>Tamarindus indica </em>juice (G3),  that received 0.5 mL of tamarind juice twice daily for 40 days. Groups G1, G2 and G3 received the drinks by intragastric rout. After this period the animals were sedated with sodium pentobarbital for blood collection and evaluation of the biochemical profile: total cholesterol, HDL-c, LDL-c, triglycerides and glucose. Atherogenic indexes were also calculated. The results showed a reduction of total cholesterol, LDL-c, triglyceride, body weight and atherogenic indices; and increase in the levels of HDL-c. We may suggest that the use of mint and tamarind juice can positively affect the biochemical parameters and reduce the atherogenic indexes of Wistar rats.</p>

The toxic effect of the aqueous extract of the bark of the root of Morinda morindoides was studied in 24 sexually matured, male Wistar rats weighing between 150-200g. The rats were randomly divided into four groups (I-IV). Rats in groups I, II and III received 400 mg/kg, 800 mg/kg and I,600 mg/kg of 50mg/ml of the aqueous extract respectively once daily for 28 days while the control group (Group IV) was given distilled water (5ml/kg) once daily for 28 days after which the rats were euthanized. Following euthanasia, about 3 ml of blood was collected and was divided into 1.5ml each for haematology and serum chemistry. In addition, samples of the kidney, liver, heart, lungs and spleen were also harvested for histopathology. Haematological and serum biochemical values were expressed as mean ± standard error of mean and were analyzed using One-way Analysis of Variance (ANOVA) followed by Duncan’s multiple range test. Lesions observed in histopathology were scored as mild, moderate or severe. Results were considered statistically significant at 95% confidence interval (P<0.05). In this study, there was no significant difference in the haematological parameters, alanine aminotransferase and aspartate aminotransferase between the treated groups and the control. Histopathologically, the extract caused mild, diffuse degeneration of the liver, mild tubular nephrosis; mononuclear cellular infiltration in the heart and mild hypoplasia of the lymphoid nodules in the spleen of rats to which 1,600 mg/kg of the extract was administered. It was therefore concluded that aqueous extract of the root of Morinda morindoides may produce subchronic toxicity at the dosage of 1600mg/kg.

Abstract The main aim of the study was to assess whether the presence of biphosphate pamidronate (PA) in the cement implanted into the tibial bones had any effect on the chosen biochemical markers in rat’s serum characterising homeostasis. Forty adult male Wistar rats were divided into two control groups and two experimental groups. Tibial bone of rats in the experimental groups was implanted with PA-enriched cement, whereas the bone in control-group’s rats was implanted with cement without PA. Serum activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatine kinase (CK) were determined three and six weeks after the surgery. Statistically significant differences in the activities of AST and CK of the rats after implantation with non-enriched cement when compared to rats given PA-enriched cement implantation, were found. Six weeks after treatment, AST levels decreased significantly in rats with PA-enriched cement, whereas rats in the control group (implanted with non-enriched cement) demonstrated a significant increase in AST activity in comparison to the same values determined after three weeks and values of PA-enriched cement rats determined after six weeks. The activities of CK were higher in rats with PA-enriched implants than in the control group three weeks after surgery, but six weeks after the treatment, rats implanted with enriched cement reached lower values than animals implanted with non-enriched cement. The use of PA in the cement had also some positive effect on the homeostasis of the rats after the surgery and a positive influence on the post operative muscle regeneration process.

Hypercholesterolemia is an important risk factors of atherosclerosis. Bitter leaf is believed to have potency in decreasing plasma lipid. The aim of this study is to study the effect of bitter leaf ethanol extract in decreasing total cholesterol serum levels on hypercholesterolemic male Wistar rats. This is a true experimental laboratory study with complete randomized design. Antidyslipidemia effect was tested with HFF induction and Propiltiourasil 0,01% towards 30 rats which were divided into 6 groups: groups I as normal control (standard diet), groups II, III, and IV were given bitter leaf ethanol extract of 100 mg/kgBW, 200 mg/kgBW, and 400 mg/kgBW dose, group V as positive control group with Simvastatin, and group VI as negative with aquades. HFF  were given for 14 days then the study was continued for 14 days. The percentage data of the declining total cholesterol levels before and after treatments is analyzed with ANAVA, continued with LSD test. The result between group II, III, and IV with group VI shows a significant difference p<0,01. We concluded bitter leaf ethanol extract can decrease the level of total cholesterol serum of hypercholesterolmic Wistar rats.

Introduction Oxidative stress and oxygen free radicals are thought to play an important role in acute effects of a number of neurotoxic processes. 3,4-Methylenedioxymethamphetamine (MDMA, ecstasy), a ring substituted amphetamine derivate, has attracted a great deal of media attention in recent years due to its widespread abuse as recreational drug by the young generation. The aim of the present study was to evaluate the acute effects of 3,4-methylenedioxymethamphetamine on oxidative stress parameters (index of lipid peroxidation - ILP, superoxide radicals O2-, superoxide dismutase - SOD and glutathione - GSH) in frontal cortex, striatum and hippocampus in Wistar rats. Materials and methods The study included 40 male Wistar rats (200-250 g), housed 4 per cage having free access to food and water. MDMA was dissolved in distillated water and administered peroraly at 5, 10, 20 or 40 mg/kg. 8 hours following MDMA, the rats were killed by decapitation, their brains were rapidly removed and the brain structures were dissected out on ice and analyzed biochemically. Results Acute peroral administration of a single dose (5, 10, 20 and 40 mg/kg) resulted in increase of ILP, O2-, SOD and decrease of GSH. Conclusion The results obtained in the present study suggest that oxidative stress plays a crucial role in MDMA-induced neurotoxicity and that the mechanism of MDMA neurotoxycity may vary between brain regions.

<p>Overweight, whose prevalence is increasing, is caused by unbalanced consumption patterns such as high consumption of fat and can trigger hypercholesterolemia. Analog rice (AR), which has better nutritional content than ordinary rice, is thought to have beneficial effects on health. This study aimed to determine the potential of analog rice in reducing body weight and total cholesterol levels. A total of 24 male Wistar rats were divided into four groups, namely: I) control, II) ordinary rice treatment, III) analog rice 1 treatment (PBA1) and IV) analog rice 2 treatment (PBA2). The control group was given standard feed for 40 days ad libitum. Groups II, III, and IV were given a combination induction of high-fat diet (HFD) for 40 days ad libitum and intraperitoneal injection of streptozotocin (STZ) 35 mg/kg single dose on day 33. All groups were then given the treatment of diet for three weeks according to their respective groups, namely the standard, ordinary rice, analog rice 1, and analog rice 2 feed. Body weight and total cholesterol levels were measured in the pre-induction, post-induction/pre-treatment (pre-test), and post-treatment (post-test). The results of the study showed that the induction of the HFD-STZ combination carried out resulted in a significant increase in body weight and total cholesterol levels. Measurements made after dietary therapy showed that body weight and total cholesterol levels in the I and II groups did not change significantly, whereas those in the III and IV groups decreased significantly (p&lt;0.05). This study concluded that the administration of analog rice could reduce body weight and total cholesterol levels in overweight and hypercholesterolemia rats. </p>

The Given

The effects of fentanyl, ketamine and thalamonal on some biochemical parameters of ethanol-treated and untreated dogs, were studied. The study was carried out on mongrel dogs. The animals were divided into two main groups: one which had free access to food and to 12% (v/v) ethanol, instead of water, and a control group which had food and water ad libitum. The animals in both groups were exposed to the action of anaesthetics for 3 h. The results show that, under the given experimental conditions, the anaesthetics did not significantly change the investigated parameters of blood and liver, either in ethanol-treated or untreated dogs. However, the action of ethanol caused remarkable changes in almost all the investigated parameters. An increased content of cytochrome P450 caused by the action of ethanol suggests possible changes in the metabolism of anaesthetics, which should be of concern to anaesthetists when dealing with patients potentially intoxicated with ethanol.
