Histopathologic Findings

Different potentially therapeutic approaches to prevent or attenuate gentamicin sulfate (GM) induced nephrotoxicity have been proposed. The present study was conducted to investigate the effect of the saffron petals extracts (<em>Crocus sativus</em>) (SPE) on male Wistar rats with kidney failure. Rats (40) were randomly assigned into five groups of 8 animals each: i) the control group, that received normal saline (0.5 mL/kg); ii) the GM group, that received GM (80 mg/kg) by intraperitoneal (i.p.) injection on a daily basis; iii) the <em>GM+SPE</em> group that received the same dose of GM and SPE (40 mg/kg) by i.p. injection on a daily basis; iv) the <em>GM+2SPE</em> group, that received the same dose of GM and twofold of SPE (80 mg/kg) by i.p. injection on a daily basis; whereas v) <em>2SPE+GM</em> group, that received 80 mg/kg of SPE a week before initiating the treatment with GM (prevention group). Significant differences were seen in the concentration of glucose, blood urea nitrogen (BUN), and creatinine between treatment groups and control in the male Wistar rats. GM was observed to cause nephrotoxicity, which was evidenced by an elevation of serum BUN and creatinine levels. The biochemical findings of the current study are concordant with those of histopathologic findings. The results of this study indicate that SPE especially in dose of 40 mg/kg can ameliorate harmful effects of GM on the kidney. The present results may suggest that the SPE have ameliorative effects on kidney failures induced by GM.

The metabolic response to nutrient ingestion and the rate of digestion and absorption of nutrient molecules in bowel physiology plays an important role in the metabolic control of some human chronic non-infectious diseases. This experimentally-controlled designed nutritional study which lasted eight weeks aimed to determine the effects of proportional high-protein/low-carbohydrate (HP/LC) formulated diet on glycemic tolerance, glycemic control, body weight, organ weight and organ morphometry in healthy and diabetic adult male Wistar rats. Twenty-four male Wistar rats purchased from a disease-free stock were randomly categorized into four groups (n = 6, each) after two weeks acclimatization period in raised stainless steel cages with 6 mm2mesh floor and replaceable numbered blotters papers placed under each cage in a well-ventilated animal house. Animal groups include: Healthy control group (HC), Healthy treated group (HT), Diabetic control group (DC) and Diabetic treated group (DT. The animals were fed according to the experimental design with water ad libitumfor eight weeks. Diabetes was inducted with freshly prepared alloxan monohydrate solution (150 mg/kg bw, intraperitoneally). Body weights and fasting blood sugar concentrations were measured twice weekly, while oral glucose tolerance test was conducted on the last day of the eighth-week study and subsequently followed by organs extraction after anesthesia for weight and gross assessment. Proportional high-protein/low-carbohydrate formulated diet caused significant reduction in mean body weight of treated diabetic (DT: 22.6%; P= .001) and healthy (HT: 5.8%; P= .007) rats while the control animals on control diet recorded significant (P< .05) increase in body weight gain (DC: 12.4%; HC: 11.2%). Glycemic tolerance and control improved significantly in diabetic treated rats over that of the healthy treated rats. Gross morphometry of the extracted organs (kidneys, liver, heart, lungs, spleen and testes) revealed sustained normal morphological features without any visible lesion. In conclusion, consumption of proportional high-protein/low-carbohydrate formulated diet enhanced body weight reduction and sustained normal organ morphological features with good glycemic tolerance and control in experimental rats, suggesting its dietary potentiality, safety and suitability to ameliorate obesity-related diabetes.

One major challenge with the use of anticancer agents is the phenomenon of drug-induced toxicity. Melphalan (MPLN) is an alkylating anticancer agent, while quercetin (QCT) is an antioxidant. We investigated the protective role of quercetin against MPLN-induced toxicity. Twenty-five male Wistar rats (160–170 g) were randomized into five treatment groups; (I) control, (II) MPLN (0.2 mg/kg b.w.), (III) pre-treated with QCT (20 mg/kg b.w.) for 7 days followed by MPLN (0.2 mg/kg b.w.) for 7 days, (IV) cotreated with QCT (20 mg/kg b.w.) and MPLN (0.2 mg/kg b.w.) for 7 days, and (V) QCT (20 mg/kg b.w.) alone. MPLN caused a significant increase in plasma bilirubin, urea, and creatinine by 122.2%, 102.3%, and 188%, respectively (P<0.05). Similarly, plasma ALP, ALT, AST, and γ-GT activities increased significantly by 57.9%, 144.3%, 71.3%, and 307.2%, respectively, relative to control. However, pre or cotreatment with QCT ameliorated the levels of renal and hepatic function indices. Hepatic ascorbic acid and GSH and activities of glutathione-S-transferase, SOD, and catalase decreased significantly by 36.2%, 188%, 46.5%, 34.4%, and 55.2%, respectively, followed by increase in MDA content by 46.5% relative to control. Pre- and cotreatment with QCT reestablished the hepatic antioxidant status and lipid peroxidation. Overall, quercetin protected against MPLN-induced renal and hepatic toxicity in rats.

ABSTRACT Excessive energi consumption of high-fat diet increase the body’s adipose tissue which also affect the increased secretion of leptin, this is because leptin secretion is proportional to the mass of adipose tissue. Leptin activates the lateral hypothalamus as the center of hunger and feeding activity. The aim of this study was to obtain the relationship between high trans fat feeding on male Wistar rats and feeding activity. This method uses male Wistar rats (Rattus norvegicus) as an animal model. Sixteen rats were grouped into 4 treatment groups. The first group was given additional feed 20% trans fat, the second group was given additional feed 40% trans fat, a third group was given additional feed 60% trans fat, and the last as a control group. This feed was given once a day for 70 days. Observation of activities perform using Opto-varimex® auto-track system ver. 4.31. The results showed an corellation between activity based doses of trans fat. Keywords: Opto-varimex®, Trans fat, Activity, Wistar rat.

Neuropeptide Y (NPY) plays a mediatory role in cerebral insulin function by maintaining energy balance. The current study was designed to determine the role of insulin in food intake and its interaction with NPY receptors in 8 experiments using broiler cockerels (4 treatment groups per experiment, except for experiment 8). Chicks received control solution or 2.5, 5, or 10 ng of insulin in experiment 1 and control solution or 1.25, 2.5, or 5 μg of receptor antagonists B5063, SF22, or SML0891 in experiments 2, 3, and 4 through intracerebroventricular (ICV) injection, respectively. In experiments 5, 6, and 7, chicks received ICV injection of B5063, SF22, SML0891, or co-injection of an antagonist + insulin, control solution, and insulin. In experiment 8, blood glucose was measured. Insulin, B5063, and SML0891 decreased food intake, while SF22 led to an increase in food intake. The hypophagic effect of insulin was also reinforced by injection of B560, but ICV injection of SF22 destroyed this hypophagic effect of insulin and increased food intake (p < 0.05). However, SML0891 had no effect on decreased food intake induced by insulin (p > 0.05). At 30 min postinjection, blood sugar in the control group was higher than that in the insulin group (p < 0.05). Therefore, the NPY1 and NPY2 receptors mediate the hypophagic effect of insulin in broiler cockerels.

Background: There is a folk belief that drinking Ramsar spring mineral water (RSW) is a remedy for renal stones. Objectives: This study aimed to evaluate the effect of RSW on prevention or treatment of nephrolithiasis in male Wistar rats and identify the constituents of the water. Methods: Nephrolithiasis was induced by providing drinking water containing 1% ethylene glycol (EG) for two weeks in male Wistar rats. The animals were divided into prevention and treatment groups, each contained five sub-groups (10 rats for each). Prevention groups were treated for two weeks: control group (without treatment), EG group (1% ethylene glycol in drinking water), RSW 5, 10, and 15% groups (1% ethylene glycol + RSW 5, 10, and 15% in drinking water). The treatment groups received 1% EG for two weeks, then it was discontinued, and the RSW (10, 15, and 20%) was added to the drinking water for the next two weeks. The calcium oxalate (CaOx) depositions in the kidneys' tubules were evaluated by Hematoxylin and Eosin staining. The spring water was analyzed for its constituents. Results: Calcium oxalate crystals were significantly increased in EG group as compared to the control group (P < 0.05). Moreover, RSW did not significantly prevent CaOx crystals but alleviated CaOx crystals at 15 and 20% concentrations in the treatment protocol (P < 0.001). Conclusions: The hard water of Ramsar spring reduced CaOx crystals in nephrolithiatic rats, which may be due to its high calcium and magnesium content.
