Background and Objective: Lead threaten living creature’s life as air pollutant and causes several diseases such as degenerative disease of nervous system. This research was conducted to determine the effect of Curcumin on BDNF changes and oxidative/antioxidative process in rat’s hippocampus which exposed to Lead acetate.

Materials and Methods: In this experimental study, 40 male Wistar rats were randomly assigned to four groups of ten: Base, Sham(control), lead and Curcumin+Lead. lead and Curcumin+Lead groups received 20 mg/kg lead acetate and Curcumin+Lead group also received 30 mg/kg Curcumin, peritoneally for 8 weeks (3 days in weeks). MDA (oxidative stress biomarker) and TAC (total antioxidative capacity) levels were measured by TBARS and FRAP methods, respectively, and hippocampus BDNF level was measured by ELISA method in rat hippocampus region. Data was analyzed by one-way ANOVA test and Tukey at P<0.05 level.

Results: Injection of lead acetate significantly increased MDA, non-significantly decreased hippocampus BDNF and significantly decreased TAC levels in the Lead group compared with control groups. On the other hand, curcumin administration led to non significantly decreased MDA, nonsignificantly increased BDNF and significantly increased TAC levels compared with other groups (P<0.05).

Conclusion: This study showed that Curcumin adminstration in long term lead acetate-treated male Wistar Rats did not increased BDNF of hippocampus, but it prevent the reduction of BNDF due to lead-intoxification.

Background and Objective: The reactive oxygen species (ROS) continuously are neutralized by antioxidant. Biological molecules become protected from oxidative stress under normal conditions. The production of ROS during hypoxia is reported In Vitro which is also known as reductive stress. In order to study this phenomenon at physiologic scales which occurs in routine activities, this study was conducted to evalute, the effect of voluntary apnea on serum ROS level. Materials and Methods: In this semi-experimental study, the participants were 12 healthy non-athlete men aged 21±3 years. At the end of normal depth inspiration the voluntary apnea had been started till 40 seconds. The respiratory rate and depth, heart rate and arterial oxyhemoglobine saturation percent were continuously monitored. Venous blood samples were collected at two times: (1) immediately after the apnea and (2) at the end of it and before re-breathing. The serum ROS level was measured using the standard D-ROM test. Results: The mean and the range of breath holding time were 52.5±7.9 and 40±61.7 seconds respectively. The heart rate and the arterial oxyhemoglobine saturation percent decrease 12.75% (P<0.003) and 2.05% (P<0.001) respectively. The mean and the range of basal vs. apnea of these parameters were as follow: 93.3±3.03 and 87-107 bpm vs. 81.43±3.7 and 71-93 bmp 97.6±.16 and 97-98 percent vs. 95.6±.33 and 94-97%. The serum ROS level after 40 seconds of apnea did not show significant differences. Conclusion: In non-athletes the voluntary apnea had no effect on serum reactive oxygen species level.

Background and Objective: Oxidative damage associated with the presence of Lead in the brain has been proposed as one possible molecular mechanism involved in Lead toxicity. Aerobic exercise is known to protect the brain through a cascade of molecular and cellular processes. The purpose of this study was to investigate the effect of 8 week aerobic training on the brain-derived neurotrophic factor (BDNF) and malondialdehyde (MDA) levels in rat's cerebellum exposed to Lead acetate. Materials and Methods: In this experimental study, 40 Male Wistar rats were randomly allocated into four groups: sedentary base, sham (30 mg/kg of ethyloleate), Lead and exercise+Lead (20 mg/kg Lead acetate, intraperitoneally). The exercise program consisted of progressive running training on the treadmill for 15 to 22 m/min, 25 to 64 min/day, and 5 days/week for 8 weeks. BDNF and MDA levels were measured by ELISA and TBARS methods, respectively. Results: Chronic Lead acetate administration enhanced significantly (P<0.05) cerebellar MDA levels in rats compare to base and sham groups but had no effect on BDNF levels. Cerebellar MDA significantly was reduced and BDNF non significantly was increased in Lead acetate+ training group. Conclusion: Regular aerobic exercise with moderate intense may exert role neuroprotective against Lead-induced cerebellar injury by down-regulating oxidative stress and promotes brain health through increases in BDNF.

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: Fenvalerate is a component of the pyrethroid pesticide induces oxidative stress. This study was done to determine the effect of garlic extract (GE) and N-acetylcysteine (NAC) against fenvalerate-induced oxidative stress in the serum and testis tissue of rat.

Methods: In this experimental study, 42 Wistar rats were randomly allocated into 7 groups including: control group, sham group (normal saline), the first experimental group receiving NAC (80 mg/kg/bw), the second experimental group receiving fenvalerate (10 mg/kg/bw), the third experimental group receiving fenvalerate (10 mg/kg/bw) + garlic extract (40 mg/kg/bw), the fourth experimental group receiving fenvalerate (10 mg/kg/bw) + NAC (80 mg/kg/bw) and the fifth experimental group receiving fenvalerate (10 mg/kg/bw) + garlic extract (40 mg/kg/bw) + NAC (80 mg/kg/bw). Injection of fenvalerate was performed intraperitoneally for 7 consecutive days in animals of intervention groups. Afterwards, for 10 consecutive days, NAC and garlic extract were injected. In this study, 1/40 LD50 fenvalerate was used. The activity of the catalase (CAT), glutathione S-transferase (GST), malondialdehyde (MDA) and total antioxidant capacity (TAC) were determined in serum and testis tissue in all animals.

Results: MDA level of serum and testis tissue in fenvalerate group increased significantly compared to the control group (P<0.05). The injection of NAC and garlic extract alone (P<0.05) as well as garlic extract in combination with NAC reduced MDA level of serum and testis tissue compared to fenvalerate group (P<0.05). Serum TAC level was significantly reduced in fenvalerate group compared to control (P<0.05). Serum TAC level was significantly increased in fenvalerate + GE group, fenvalerate + NAC group and fenvalerate + GE + NAC group compated to the fenvalerate group (P<0.05). GST activity of serum was significantly increased in fenvalerate group compared to control (P<0.05). GST activity of serum was significantly reduced in NAC, garlic extract and combination of NAC and garlic extact groups compared to fenvalerate group (P<0.05).

Conclusion: In this animal model study, low dose (10 mg/kg/bw) fenvalerate induces oxidative stress. Garlic extract and N-acetylcysteine (alone and in combination) improve injures caused by fenvalerate.

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.
Conclusion: Thymoquinone can attenuate oxidative stress markers in a dose-dependent manner.

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.
