Chronic Immobilization Stress

Abstract. Alterations of essential elements in the brain are associated with the pathophysiology of many neuropsychiatric disorders. It is known that chronic/overwhelming stress may cause some anxiety and/or depression. We aimed to investigate the effects of two different chronic immobilization stress protocols on anxiety-related behaviors and brain minerals. Adult male Wistar rats were divided into 3 groups as follows ( n = 10/group): control, immobilization stress-1 (45 minutes daily for 7-day) and immobilization stress-2 (45 minutes twice a day for 7-day). Stress-related behaviors were evaluated by open field test and forced swimming test. In the immobilization stress-1 and immobilization stress-2 groups, percentage of time spent in the central area (6.38 ± 0.41% and 6.28 ± 1.03% respectively, p < 0.05) and rearing frequency (2.75 ± 0.41 and 3.85 ± 0.46, p < 0.01 and p < 0.05, respectively) were lower, latency to center area (49.11 ± 5.87 s and 44.92 ± 8.04 s, p < 0.01 and p < 0.01, respectively), were higher than the control group (8.65 ± 0.49%, 5.37 ± 0.44 and 15.3 ± 3.32 s, respectively). In the immobilization stress-1 group, zinc (12.65 ± 0.1 ppm, p < 0.001), magnesium (170.4 ± 1.7 ppm, p < 0.005) and phosphate (2.76 ± 0.1 ppm, p < 0.05) levels were lower than the control group (13.87 ± 0.16 ppm, 179.31 ± 1.87 ppm and 3.11 ± 0.06 ppm, respectively). In the immobilization stress-2 group, magnesium (171.56 ± 1.87 ppm, p < 0.05), phosphate (2.44 ± 0.07 ppm, p < 0.001) levels were lower, and manganese (373.68 ± 5.76 ppb, p < 0.001) and copper (2.79 ± 0.15 ppm, p < 0.05) levels were higher than the control group (179.31 ± 1.87 ppm, 3.11 ± 0.06 ppm, 327.25 ± 8.35 ppb and 2.45 ± 0.05 ppm, respectively). Our results indicated that 7-day chronic immobilization stress increased anxiety-related behaviors in both stress groups. Zinc, magnesium, phosphate, copper and manganese levels were affected in the brain.

Abstract Background Dependence and tolerance to morphine are major problems which limit its chronic clinical application. Purpose This study was aimed to investigate the attenuation effect of Cerebrolysin, a mixture of potent growth factors (BDNF, GDNF, NGF, CNTF etc,), on the development of Morphine-induced dependence and tolerance. Methods Male Wistar rats were selected randomly and divided into different groups (n=8) including: a control group, groups received additive doses of morphine (5–25 mg/kg, ip, at an interval of 12 h until tolerance completion), and groups pretreated with Cerebrolysin (40, 80 and 160 mg/kg, ip, before morphine administration). Development of tolerance was assessed by tail-flick test and the attenuation effect of Cerebrolysin on morphine-induced dependence was evaluated after injection of naloxone (4 mg/kg, ip, 12 h after the morning dose of morphine). Seven distinct withdrawal signs including: jumping, rearing, genital grooming, abdominal writhing, wet dog shake and teeth grinding were recorded for 45 min and total withdrawal score (TWS) was calculated. Results Results showed that administration of Cerebrolysin could prolonged development (10 and 14 days in administration of 80 mg/kg and 160 mg/kg Cerebrolysin) and completion (4, 10 and 14 days in administration of 40, 80 and 160 mg/kg Cerebrolysin, respectively) of tolerance. Results also indicated that administration of Cerebrolysin (40, 80 and 160 mg/kg) could significantly decreased the TWS value (62±2, 77±4 and 85±6%, respectively). Conclusion In conclusion, it was found that pretreatment with Cerebrolysin could attenuated morphine-induced tolerance and dependence.

The aim of this study was to investigate the dose-related effects of fenitrothion (FNT) on the liver and kidney. The study was conducted on 8-week-old male Wistar rats that were divided into four groups (three experimental groups and one control group) and were treated orally with different doses (25, 50, 100 mg/kg) of FNT for 28 consecutive days. After treatment, the rats were anesthetized with ether and liver and kidney samples were taken for histological studies. The results showed that the histopathological changes in the liver were mainly represented by parenchymatous degeneration of hepatocytes with mild necrosis, leukocytic infiltration in the portal area, severe congestion, and hemorrhage. These changes were dose dependent. Marked tubular dilation, hydropic degeneration in tubular epithelium, moderate congestion, and hemorrhage in the cortical and medulla part of the kidney were recorded. Histopathologic examination of the liver and kidney indicated a significant injury only in rats receiving 100 mg/kg FNT.

AbstractCadmium (Cd) and diazinon (DZN) are known to be environmental risk factors for various bone diseases including osteoporosis. Selenium (Se), an essential constituent of many antioxidant enzymes, has in higher concentrations negative effects on the bone. The present study was aimed to investigate possible changes in femoral bone of adult male rats after their acute and subchronic exposures to Cd, DZN and Se. A total of 30 male Wistar rats were randomized into three experimental groups. The rats in the group A (4-months-old) were injected intraperitoneally with a mixture of 2 mg CdCl2 kg−1, 20 mg DZN kg−1 and 2 mg Na2SeO3 kg−1 body weight and killed 36 h after xenobiotics had been injected. In the group B, young males (1-month-old) were administered with a combination of 30 mg CdCl2 L−1, 40 mg DZN L−1 and 5 mg Na2SeO3 L−1 in their drinking water, for 90 days. Ten 4-months-old males without toxicant supplementation served as a control group (C). After treatment period, detailed histological analysis of femoral bone was performed in each group. Our results revealed apparent osteoporotic symptoms (resorption lacunae, osteoporotic fractures) in rats from groups A and B. Moreover, histomorphometrical evaluation showed reduced bone vascularization (constricted primary osteons’ vascular canals and Haversian canals) and weakness mechanical properties of bones (smaller size of the secondary osteons) in these rats in comparison with those of the control group. Our study demonstrates for the first time that acute and subchronic co-administrations to Cd, DZN and Se induce evident manifestation characteristics of osteoporosis in male rats.

Introduction: The neuropeptide Y (NPY) in the neural circuits of the hypothalamus has a stimulating effect on reproductive activities in mammals. Kisspeptin (KiSS1) is a quintessential neurotransmitter in the reproductive axis which directly stimulates gonadotropin-releasing hormone neurons in the hypothalamus. The distribution of KiSS1 expressing cells in the pituitary was described previously. Despite earlier reports showing the KiSS1 receptor, G-protein coupled receptor 54 (GPR54) expression in the pituitary, the potential physiological roles of kisspeptin at this gland have remained obscure. Accordingly, this study investigated the role of NPY on the relative expression of Kiss1 and Gpr54 genes in the pituitary gland in male Wistar rats. Methods: In general, 20 male Wistar rats weighing 200-250 g in 4 groups (5 in each group) received saline, NPY (2.3 nM), BIBP3226 (NPY receptor antagonist, 7.8 nM), and NPY+ BIBP3226. Then, they received the simultaneous injection of these molecules through the third ventricle of the brain. Finally, the relative mean expressions of Kiss1 and Gpr54 genes in the anterior pituitary were quantitatively analyzed by the real-time polymerase chain reaction. Results: The central injection of NPY increased the relative mean expressions of Kiss1 and Gpr54 genes in the pituitary gland compared to the control group although the injection of BIBP3226 eradicated these effects. However, the gene expression of Gpr54 in the rats receiving NPY coupled with BIBP3226 in hypophysis in comparison to the group receiving only NPY demonstrated a significant reduction (P<0.05). Conclusion: Overall, the central injection of NPY stimulated the gene expression of Kiss1 and Gpr54 in the pituitary gland.

Abstract Objective: Neurotoxicity is an adverse effect caused by cisplatin due to inflammation and oxidative stress in the central nervous system. The present study aimed to assess the effects of vitamin E injection on the learning and memory of rats with cisplatin-induced cognitive impairment. Methods: Male rats were administered with cisplatin (2 mg/kg/7 day; intraperitoneally [i i.p.]) and/or vitamin E (200 mg/kg/7 day; i.p.) for 1 week, and the control group received saline solution. Spatial memory was evaluated using Morris water maze (MWM). In addition, the hippocampal concentrations of malondialdehyde (MDA), thiol, and superoxide dismutase (SOD) were measured using biochemical methods. Results: According to the findings, cisplatin significantly increased the escape latency, while decreasing the time spent and travelled pathway in the target quadrant on the final trial day compared to the control group. Furthermore, pre-treatment with vitamin E significantly reversed all the results in the spatial memory test. The biochemical data indicated that vitamin E could decrease MDA activity and increase thiol and SOD activity compared to the control group. Conclusion: According to the results, vitamin E could improve cisplatin-induced memory impairment possibly through affecting the hippocampal oxidative status.

AbstractStanozolol is an anabolic-androgenic steroid which is commonly abused by athletes for improved energy, appearance, and physical size. It has been previously shown to cause changes in behaviour and has various physical effects. Studies have previously been conducted on its neurotoxic effect on the central nervous system (CNS), which are typically psychological in nature. This study was performed to investigate the apoptotic effect of stanozolol on different parts of the rat hippocampus. Sixteen male Wistar rats were divided randomly into two groups (experimental and control). The experimental group received subcutaneous injections of stanozolol (5mg/kg/day) for consecutive 28 days, whereas the control group received saline using the same dosing schedule and administration route. After routine procedures, coronal sections of rat brain were stained with Toluidine blue and TUNEL for pre-apoptotic and apoptotic cell detection, respectively. In order to compare groups, the mean number of TUNEL-positive and pre-apoptotic neurons per unit area were calculated and analysed. Histopathological examination revealed that the mean number of pre-apoptotic and apoptotic neurons in the CA1, CA2, CA3 and DG areas of the hippocampus were significantly increased in the stanozolol treated group. In conclusion, stanozolol abuse may induce pre-apoptotic and apoptotic cell formation in different regions of the hippocampus.

Acute exercise induces rapid and dramatic induction of transcription in the liver. The beneficial effects of carnitine on serum factors and gene expression have been proven. This study examined the interaction between acute exercise and carnitine supplementation on the expression of genes involved in liver metabolism. Thirty-two male Wistar rats were randomly assigned into 4 groups (n = 8): Group 1 control, Group 2 received 200 mg/kg/day LCAR, Group 3 performed acute exercise, and Group 4 received LCAR and performed acute exercise. Gene expression in the liver was evaluated by Real-time PCR. Acute exercise significantly increased PDK4 expression compared to other groups. Also, carnitine administration, performing an acute exercise, and combination of LCAR-Acute significantly increased AMPK and PGC-1a expression compared with the control group. The expression of SREBP-1c and SCD1 was not significantly changed between studies. The combination of acute exercise and carnitine administration increased PGC-1a expression, indicating the importance of carnitine with exercise as a beneficial supplement.

Inflammatory Effect

In the last decade, high cariesprophylactic efficacy of ammonium hexafluorosilicates, including salts with substituted biologically active ammonium cations, has been demonstrated. Among the promising anti-caries agents are recently synthesized 2-, 3-, 4-carboxymethylpyridinium hexafluorosilicates, for whose cations anti-inflammatory activity is expected. The aim of the work is to assess the presence of anti-inflammatory activity in the series of 2-, 3-, 4-carboxymethylpyridinium hexafluorosilicates in the experiment. 2-, 3-, 4-Carboxymethylpyridinium hexafluorosilicates (I–III, respectively) were synthesized according to the previously proposed technique, carrageenan is a commercial preparation, reference drug is a indomethacin. Experiments on the anti-inflammatory activity of hexafluorosilicates were performed on 77 white Wistar male rats weighing 174–190 g using the carrageenan model of inflammation. The inflammatory reaction was reproduced by subplantary administration of 0.1 ml of a 0.2% solution of carrageenan, the studied compounds were administered orally in doses 1/10, 1/20, 1/50 from LD50 for the compound III. It was established that after administration of carrageenan, animals of the control group showed marked paw edema, which gradually increased and was maximal after 24 hours of observation. According to the data obtained, the indices for compounds I-III practically do not differ from those of the control group. This indicates that, despite the results of the PASS forecast and the presence of acetic acid residue, an anti-inflammatory pharmacofor, in compounds I-III, the compounds under study do not have an anti-inflammatory effect in the carrageenan model. 2-, 3-, 4-Carboxymethylpyridinium hexafluorosilicates do not show the expected anti-inflammatory activity in the carrageenan model of inflammation.
