Background and Objective: Hydroalcholic extract of Peppermint is traditionally used for gastrointestinal disorders. This study was done to evaluate the effect of Peppermint extract on the mice colon motor activity following immobilization stress.

Methods: In this experimental study, 30 male Albino mice were randomly allocated into the three groups; including control, stress and stress + Peppermint oil groups (n=10). The second group as a stress group exposed to immobilization stress for four hours during three days. Third group as stress plus Peppermint oil group was exposed to stress in addition to administration of 27 mg/kg/bw Peppermint oil intraperitoneally prior to stress. After three days, intestinal and peristaltic activity was recorded using pressure transducer from in vitro segments of colon (4-5 cm in length. Also, fecal weight, food intake and body weight was measured for each mouse for in vivo condition.

Results: The mean±SD of fecal weight after three times stress immobilization was 1.36±0.71, 1.06±0.6 and 0.47±0.39 gr in control, stress and Stress + Peppermint oil groups, respectively (P<0.05). The mean±SD of internal luminal pressure after three times stress immobilization was 4.47±1.15, 3.48±1.25 and 0.77±0.37 mm/hg in control, Stress and stress + Peppermint oil groups, respectively (P<0.05).

Background and Objective: Gender differences in biobehavioral responses to environmental stressors and experience of psychological stress should be identified. This study was done to evaluate the changes of the level of salivary cortisol under psychological stress and its relationship with rumination and personality traits.

Methods: In this case-control study, for 45 medical students, The NEO Personality Inventory-Short Form and emotional control questionnaire (ECQ) were filed two months before the final examination. Saliva samples were taken from students in the non-stress (control) and examination stress conditions. Salivary cortisol levels were measured by ELISA method.

Results: Gender differences were not observed in the level of salivary cortisol under psychological stress. Significant difference was observed between the mean of salivary cortisol in the non-stress and under examination stress conditions. Positive correlation was found between traits of neuroticism (P<0.05) and rumination (P<0.05) with salivary cortisol as well as negative correlation between the traits openness to experience (P<0.05) and angery control (P<0.05) with salivary cortisol. Neuroticism, rumination and angery control may predict a substantial variance (32%) of salivary cortisol under exam stress.

Conclusion: Psychological stress leads to increase in the secretion of salivary cortisol unrelated to gender. Subjects with different personality traits are prone to cortisol responses to stress based on their particular character.

Background and Objective: Oxidative stress causes disorder in the brain processes including memory. Pistacia atlantica kurdica (pistachio) contains antioxidant compounds, oleic and linoleic acid. Fluvoxamine is an antidepressant medicine which inhibits serotonin reuptake. This study was done to determine the effect of hydroalcoholic extract of pistachio and fluvoxamine on spatial memory of male rats under immobilization stress.
Methods: This experimental study was done on 30 adult male Wistar rats in 5 groups (n=6). The control group was not under immobilization stress. Animals in the stress group were just under immobilization stress. Animals in the pistachio group were under immobilization stress and were received 400 mg/kg/bw hydroalcoholic extract of pistachio. Animals in the fluvoxamine group under immobilization stress were received 120 mg/kg/bw fluvoxamine. Animals under immobilization stress, in the pistachio plus fluvoxamine group were received 400 mg/kg/bw hydroalcoholic extract of pistachio and fluvoxamine 120 mg/kg/bw. The radial arm maze test was used for evaluation of spatial memory. After the animals’ decapitation, the malondialdehyde and catalase level in hippocampus and the serum level of corticosterone and blood glucose were measured.
Results: The stress significantly increased the time of reaching to target, malondialdehyde, corticoestron and blood glucose level, and reduced the catalase in stress group in comprasion with controls (P<0.05). In the pistachio and the pistachio+fluvoxamine treated groups, the time of reaching to target, malondialdehyde, corticoestron and blood glucose level significantly reduced and the catalase level significantly increased in comprasion with stress group (P<0.05) but fluvoxamine significantly increased the time of reaching to target, malondialdehyde and blood glucose, and reduced the corticoestron and catalase in compared to controls (P<0.05).
Conclusion: The immobilization stress led to attenuation of spatial memory and the fluvoxamine administration as an antidepressant drug caused to deterioration of memory,while the treatment with pistachio extract lead to improve the memory.

Background and Objective: A brief and short duration episode of ischemia is recorded in ischemic preconditioning (IPC). This latter condition provides a status in which large region of heart is protected when prolonged ischemia occurred. Levothyroxine play a protective role in IPC induction, and simultaneously with stress oxidative. This study was conducted to determine the protective effect of levothyroxine with oxidative stress reduction mechanism in ischemic preconditioning model in rat heart.
Methods: This experimental study was performed on 30 male Wistar rats in three groups of 10, as follows. In the reperfusion ischaemia group (IR), the heart of the animal was placed in a Langendorff apparatus. In the ischemic preconditioning group (IPC), prior to major ischemia, was exposed to 4 periods of 5-minute ischemia with reperfusion. In the intraperitoneally administered group, levothyroxine at a dose of 25 microgram per 100 g of body weight, the heart was exposed to reperfusion ischemia. The area of infarct and the level of malondialdehyde in the heart tissue were measured.
Results: The volume of Infarcted region in IR and IPC groups was 26.55 and 11.11 respectively. The same index for the Levothyroxine receiver was 12.56. Based on these findings it was demonstrated that Levothyroxine injection reduced the Infarcted region significantly similar with IPC (P<0.05). The MDA Levels in IR and IPC were 1328 and 777, respectively and in Levothyroxine group it was determined as 762. The size of Infarcted region in both IPC and treated with Levothyroxine groups significantly reduced in compared to IR group (P<0.05).
Conclusion: Injection of levothyroxine with ischemic preconditioning reduced the effect of reperfusion maladaptive ischemia in rat heart.

Aging is an inevitable process, which is associated with the development of various diseases such as cardiac hypertrophy. Hypertrophy can occur in both pathological and physiological form. Both types can be divided into a variety of eccentric and concentric types. In the present review, we present the effects of aging and exercise on patological and physioligac cardiac hypertrophy, oxidative stress and some of the mitogen-activated protein kinases with using 79 articles which acceable in pubmed and SID indexing which published during 1976-2016. If the age is associated with inactivity, leads to pathological heart hypertrophy. Meanwhile, the role of the protein family of kinases activated with mitogen and oxidative stress is important. Adolescence, if accompanied by low activity, can lead to increase oxidative stress through mitochondrial dysfunction. Oxidative stress can affect the activity of MAPKs. MAPKs have important role in wide variety of biological events, such as proliferation, differentiation, metabolism, mobility, survival and apoptosis. The tipping point of signal transduction and the regulation of these biological events bigin initially by the four MAPK subunits, including extracellular signal regulated kinase (ERK1 / 2), c-Jun NH2-terminal kinase (JNK1, -2.3) kinase P38 (A, B, y, S) and large MAPKs (BMKs or ERK5s). This paper focuses on two types of ERK1 / 2 and P38 that play an important role in the development of cardiac hypertrophy. ERK1 / 2 and P38 amounts change with aging. These changes are associated with the development of pathological hypertrophy. Sports activities can control the pathological pathway of hypertrophy and can lead to physiological hypertrophy. Exercise can control or reduce oxidative stress, ERK1 / 2 and P38 and ultimately can affect cardiac hypothyroidism.

Background and Objective: Acrylamide is a neurotoxic agent that increases oxidative stress by creating an imbalance between the production and removal of free radicals, which in turn contributes to the pathogenesis of some neurodegenerative disorders. Thymoquinone extracted from Nigella satvia has prominent antioxidant effects. The objective of this study was to evaluate the effects of thymoquinone on hippocampal oxidative stress and neuronal density following acrylamide administration in male rats.
Methods: In this experimental study, 28 male Wistar rats aged 10-12 weeks and weighing 180-200 g were randomly divided into 4 groups of 7 rats: control, acrylamide, acrylamide + thymoquinone treatment (1 mg/kg), and acrylamide + thymoquinone treatment (5 mg/kg). For induction of brain injury, 50 mg/kg of acrylamide was injected intraperitoneally. Two days after the acrylamide injection, the rats were sacrificed, and malondialdehyde (MDA), glutathione (GSH), and catalase levels were measured in hippocampal homogenate. Evaluation of neuronal density in hippocampal CA1 region was also performed by Nissl staining.
Results: Acrylamide injection significantly increased MDA level and reduced GSH content and catalase activity in comparison with the control group (P<0.05). Administration of 5 mg/kg thymoquinone significantly reduced MDA level (P<0.05) but improved GSH and catalase activity in comparison with the acrylamide group (P<0.05). In addition, neuron density of hippocampal CA1 region did not differ significantly between the groups.

Background and Objective: Considering the role of diet and the use of natural antioxidants in addition to exercise, the attention of researchers has been drawn to take further advantage of the effects of exercise to improve cellular metabolism. Despite the favorable role of exercise and antioxidants on heart health, the simultaneous effect of exercise and consumption of propolis (prepared by bees) is not yet known. This study aimed to investigate the effects of endurance training and propolis against oxidative and myocardial stress in diabetic ovariectomized rats.
Methods: This experimental study was conducted on 36 female Sprague Dawley rats aged 12-16 weeks and weighing 220-250 grams. Six rats were included in the healthy control group. Diabetes was induced in 30 overiectomized rats by intraperitoneal injection of streptozotocin (40 mg/kg). Then, the diabetic animals were divided into five groups of six including diabetic ovariectomized control, sham, propolis, endurance training, and endurance training + propolis. Rats in the training groups trained for eight weeks, five sessions per week, with 55-75% VO2 max. Moreover, propolis was administered 100 mg/kg/day by peritoneal injection. The level of Pro-oxidant-antioxidant balance (PAB) and expression of HSP72 and NF-κB genes were measured.
Results: HSP72 expression was significantly higher in the propolis, endurance training, and endurance training + propolis groups. The levels of NF-kB and malonaldehyde were significantly decreased in the ovariectomized diabetic rats (P<0.05). Expression of HSP72 in the endurance training and endurance training + propolis groups were significantly higher than in the propolis group. Moreover, NF-kB in the endurance training and endurance training + propolis groups were significantly lower than in the propolis group (P<0.05). The value of PAB in the propolis and endurance training + propolis groups were significantly lower than in the ovariectomized diabetic rats (P<0.05).
Conclusion: Exercise and consumption of propolis seem to synergistically improve the protective HSP72 pathway and reduce oxidative stress in heart tissue following estrogen dysfunction and diabetes. However, the interaction of the two depends on endurance training.

Background and Objective: Sodium valproate (SV) is a commonly used antiepileptic drug; however, its therapeutic application is limited due to its potential to induce oxidative stress. Resveratrol, a natural polyphenol, possesses antioxidant properties. This study was conducted to determine the effect of resveratrol on SV-induced oxidative stress in the hippocampal tissue of BALB/c mouse fetal brains.
Methods: In this experimental study, 40 pregnant female BALB/c mice were randomly assigned to 5 groups of 8, including control, SV at 40 mg/kg/bw, SV at 40 mg/kg/bw + resveratrol at 0.6 mg/kg/bw, SV at 40 mg/kg/bw + resveratrol at 0.35 mg/kg bw, and SV at 40 mg/kg/bw + resveratrol at 0.225 mg/kg/bw. SV was administered orally per day, and resveratrol was administered daily via intraperitoneal injection. From gestational day 8 to 18, pharmacological interventions were initiated and continued until the birth of the neonates. On gestational day 18, the maternal mice were anesthetized, and 8 fetuses from each group were separated. Following the anesthesia of the fetuses, the brain tissue was dissected. Subsequently, oxidative stress parameters, including the malondialdehyde (MDA) level in nmol/mg as an index of lipid peroxidation, glutathione (GSH) level alterations in µg/mg, and protein carbonyl (PC) level alterations in nmol/mg, were evaluated in the hippocampal tissue.
Results: SV induced oxidative stress by increasing MDA (4.8 nmol/mg) and PC (51.4 nmol/mg protein), and also decreasing GSH (31.86 μg/mg) in the brain tissue compared to the control group (P<0.05). In a concentration-dependent manner, resveratrol reduced oxidative stress by decreasing MDA and PC to 3.02 and 37.21 nmol/mg, respectively, and also by increasing GSH to 49.76 μg/mg in the brain tissue. The most significant effect was observed at a concentration of 0.6 mg/kg/bw, which was statistically significant compared to the SV group (P<0.05).
Conclusion: The combined administration of SV and resveratrol culminates in a reduction in inflammation and oxidative stress-related factors in mouse fetuses.
