Background: The present study was designed to evaluate the effect of intra-central amygdala nucleus (CeA) administration of methyl jasmonate (MeJA) on anxiety-like and social behaviors in adult male rats exposed to acute stress.Materials and Methods: The adult male rats were bilaterally cannulated in CeA. The rats were subjected to restraint stress conditions 1 h daily for a week. Then, the rats were treated with intra-CeA administration of MeJA (2.5, 5 and 10 µg/rat). Rats’ behaviors were assessed in elevated plus maze (EPM), open field (OF), and a three-chambered social approach task, respectively.Results: Rats exposed to restraint stress showed significant anxiogenic behaviors in EPM and OF tasks. However, bilateral microinjection of MeJA (5 and 10 µg/rat) in CeA decreased stress induced anxiety-like behavior indices in both tasks (p<0.01, p<0.05). In addition, stressed rats showed social behavior deficits in the three-chambered social approach task (decreased sniffing time and time spent in compartment with stranger rats) as compared to untreated control rats. However, MeJA (10 µg/rat) ameliorated social behavior deficiency in stressed rats.Conclusion: The data of this study showed MeJA value for attenuating stress-induced anxiety-like and social behavior deficits in rats.

Introduction: There has been no report on the effect of epilepsy on liver enzymes and lipoproteins and its changes following exercisetraining in epileptic rats with Pentylenetetrazole. Materials and Methods: In this experimental study, 70 male rats were placed in 7 groups. An intact group, three groups of Kindle and three groups of non-Kindle who received PTZ or normal saline injections every 48 hours until the animals were kindled. 24 hours after Kindling, blood samples were collected in intact group and two groups of Kindle and non-Kindle. One Kindle group and one non-Kindle group from the remaining four groups performed aerobic exercise for six weeks, and the other two groups were inactive for six weeks. Blood were collected 24 hours after the 6-week period, and were compared with control groups. Results: After 4 weeks of Kindling period, total cholesterol, triglycerides, low-density lipoprotein, liver enzymes (P <0.001) and antigenic coefficient (P <0.01) increased significantly in the epileptic group. After six weeks of aerobic exercise in Kindle animals; Triglycerides (P <0.001), liver enzymes (P <0.01) and antigenic coefficients significantly reduced, and high-density lipoprotein significantly increased (P <0.01). Conclusion: The results showed that aerobic exercise in epileptic rats with Pentylenetetrazole improved lipid profile impairement and increased liver enzymes caused by epilepsy.

Background and Objective: Abuse of anabolic steroids to increase concerns about the harmful effects of these drugs on different organs, including the kidneys has increased. Sports activities such as swimming does not modify the effects of anabolic steroids. In this study, the effects of anabolic steroids with or without swimming the public and biochemical changes in renal tissue of rats was performed.Materials and Methods: The study sample consisted of 32 male rats Wistar, with an average weight of 20 ± 220 g in the form of four groups of nandrolone alone 10 mg / kg (n = 8), nandrolone and forced swim 10 mg / gr (n = 8), forced swim alone (n = 8) and controls (n = 8) were divided. In this study, urine samples were collected to measure biochemical variables. : Data obtained with the software spss version 21 Test and one-way ANOVA significant level P≤0 / 05 was performed.Results: H & E and PAS staining nandrolone decanoate + exercise groups compared with control groups and sports inflammation of the glomeruli, tubular atrophy, the number of leukocytes was more evident.Conclusion: The results of swimming exercise any impact on different parts of the kidney of male rats does not allow the use of nandrolone could be change in these sectors.Keywords: nandrolone, sports, swimming, stained H & E, coloring PAS, rats, creatinine, urea

Background and objective: Kelussia odoratissima Mozaffarian (Umbelliferae family) is one of the Iranian medicinal plants that has nutritional and pharmacological effects. In Iranian traditional medicine, it has been mentioned that this plant has anti-spasmodic effect and it is used for the treatment of gastrointestinal dysfunctions, such as abdominal pain. In this study, we evaluated the effect of alcoholic extract of Kelussia odoratissima Mozaffarian on ileum contractions in rats. Method: Alcoholic extracts were prepared from powdered Kelussia leaves. Ileum samples were placed in an organ bath containing tyrode solution and 1g tension was used before inducing ileum isotonic contraction with KCl (60 mM). Saline or extracts (10% and 20%) were added to the bath and responses were recorded. Data were analyzed using ANOVA followed by Tukey HSD test. Findings: Our results demonstrated that both concentrations of Kelussia significantly reduced the KCl-induced contraction in isolated rat ileum compared to the control (saline) group (p

Background: Minocycline is an antibiotic and anti-inflammatory drug. In addition, its neuroprotective effects have been shown. Since there is interaction between cell death and seizure, the aim of this study is examination of the role of minocycline on amygdala-kindled seizures in rat.
Materials and Methods: In this experimental study, three groups of animals (18 rats), after stereotaxic surgery and 1-week recovery period, received twice daily kindling stimulations. In fully kindled animals of groups 1-3, minocycline was injected intraperitoneally in doses 12.5 (n = 7), 25 (n = 5) and 50 (n = 6) mg/kg, respectively, 60 minutes before stimulation. Afterdischarge duration (ADD), stage 4 latency (S4L), Stage 5 Duration (S5D) and Seizure Duration (SD) were recorded and compared with related control groups (the same animals that had received saline 1 day before). A p-value of less than 0.05 was considered to represent a significant difference.
Results: In fully kindled animals who had received minocycline (50 and 25 mg/kg), ADD decreased significantly. When minocycline was delivered, S5D decreased 38.3% (p < 0.001), 34% (p

Background: Magnesium is a unique element among the trace elements, because it plays a role in a vast range of metabolic processes such as carbohydrate, lipid, protein, and the integrity of nucleic acids. Noting the role of this element in the physiological activity of organelles and tissues and the importance of the regulation of thyroid hormone levels in the body, this study considered the effect of esculent magnesium sulfate on the values of TSH, T3, and T4 hormones.
Materials and Methods: In this experimental study, 40 adult male Wistar rats weighing nearly 190-200 g were used. The rats were divided into five groups of eight: the experimental groups received 2, 4, and 8 molars of edible magnesium sulfate solution, respectively, while the control group received nothing. The sham group received only distilled water. The prescription was continued for 28 days and bleeding the heart was done to measure the mentioned factors of the serum. The mean concentration of the hormones was analyzed using suitable statistical methods, such as ANOVA and Tukey’s test, and compared between the control and experimental groups.
Results: The statistical analysis showed that the concentrations of TSH, T3, and T4 hormones increased significantly after receiving the different values of magnesium sulfate compared with the control group (p < 0.05).
Conclusion: Based on the results of this investigation, magnesium sulfate in the last 28 days increased the thyroid activity leading to increased serum levels of TSH, T3, and T4 hormones.
