Background and Objective: In recent years many studies have reported that aspirin could have beneficial effect on learning and memory in different diseases of central nervous system. The objective of present study was to explore the effect of aspirin on learning and memory of Rats in pentylenetetrazole kindling model. Materials and Methods: In this experimental study Rats were divided randomly into six groups (n=8). Animals in three groups received aspirin (15 and 30 mg/kg, orally) and saline, one week before and during induction of kindling, respectivley. Kindling was induced in these groups by administration of pentylenetetrazole (PTZ: 40 mg/kg, ip). Two groups of animals received only aspirin 25 and 30 mg/kg orally. Other group received only saline throughout the study and served as health control group. After induction of kindling the learning and memory of Rats was tested in shuttle box. Study was divided to three stages of adaptation, acquisition and retention test. Initial Latency (IL) time before electrical shock and Step through latency (STL) time, 20 min or 24h after acquisition was evaluated as learning and memory index. Locomotor activity was also evaluated in open filed test. Results: PTZ kindling significantly decreased Initial Latency and Step through latency time, 20 min or also 24h after acquisition, and aspirin significantly increased these times in kindled animals (p<0.05). Aspirin also had no significant effect on locomotor activity of animals. Conclusion: This study showed that the administration of aspirin to kindled Rats improved learning and memory impairments induced by pentylenetetrazole kindling.

Background and Objective: Increasing the intensity of training is one of the factors that improve the athletic performance. Evaluation of psychological and biochemical factors is believed to be beneficial for evaluating the effectiveness of training schedule. Previous studies have shown that there are various responses to the training intensity due to the level of athlete’s fitness and the kind of training. This study was done to investigate the effect of intensive training on salivary level of cortisol, testosterone, α-amylase and mood of elite adolescent wrestlers. Materials and Methods: This quasi-experimental study was performed on fifteen adolescent wrestlers of Iranian national team during 2009. The subjects were under extension training for three weeks. The saliva samples were taken prior, first, second and third weeks of training to determine cortisol, testosterone and α-amylase level of salivary samples. Also, the Brahms questionnaire was used to assess the mood profile before and after the training. Data were analyzed using SPSS-14, ANOVA and student t-tests. Results: There was no significant differences of salivary cortisol (7.69±0.75, 8.1±0.93 ng/ml), testosterone (82.3±0.89, 64.2±1.7 ng/ml), α-amylase (98.81±1.35, 84.2±1.5 U/ml) level and mood (16.4±3.28, 20.08±2.91) of subjects prier and after training. Conclusion: This study indicated that the intensive training do not alter salivary hormons level and mood of elite adolescent wrestlers.

Background and Objective: Oxidative stress plays an important role in the pathogenesis of some diseases such as atherosclerosis and doing high intensity training may enhance oxidative stress. This study was done to evaluate the effect of eight weeks resistance training on malondialdehyd, total, antioxidant capacity, liver enzymes and lipid profile in overweight and obese women.
Methods: In this quasi-experimental study, 16 overweight and obese women were non-randomly divided into intervention (n=9) and control (n=7) groups. The resistance training included the resistance training (with intensity of 50-80% one repetition maximum) that lasted for 8 weeks and 3 sessions per week. Every session lasted for 60 minutes. Malondialdehyd, total antioxidant capacity, liver enzymes and lipid profile for each subject was measured.
Results: The eight weeks resistance training significantly increased total antioxidant capacity high density lipoprotein and triglyceride in interventional group in compared to controls (p<0.05). The eight weeks resistance training significantly reduced alanine aminotransferase in comparison with control group (p<0.05).
Conclusion: Eight weeks resistance training by reducing malondialdehyd and increasing total antioxidant capacity may reduce the risk of atherosclerosis disease and improving cardiovascular health.

Background and Objective: Todays, coronary artery disease is one of the most important health issues. Antioxidants are the agents that can play important role in reducing cardiovascular diseases. The present study was done to determine the effect of resveratrol supplementation during rehabilitation exercises training on systemic inflammation factors in patients after coronary artery bypass surgery.
Methods: This clinical trial study was done on 40 patients after coronary artery bypass surgery in the heart rehabilitation center of Farshchian cardiovascular specialist hospital in Hamadan, Iran during 2016. Patients randomly assigned into four groups including control (Con; n=10), resveratrol supplementation (RS; n=10), rehabilitation exercise training (RXT; n=10), and resveratrol supplements-cardiac rehabilitation exercise training (REX; n=10). Rehabilitation exercise training was done in nonconsecutive three sessions for eight weeks in the form of endurance training at 50-70% HRmax for 15-20 min, and resistance training at 20-50 one-repetition maximum (1RM). The number of repetitions was 8-15 reps, where done based on the capacity and ability of the subject, while the subjects in supplement groups consumed daily 400 mg of resveratrol. Blood sample was done before and 48 hours after exercise training and supplementation, and concentrations of Tumor necrosis factor alpha (TNFα), Interleukin- 6 (IL-6), Interleukin 1 beta (IL-1β) and C-reactive protein (CRP) were measured in the plasma.
Results: CRP, TNF-alpha and IL-1beta and IL-6 were significantly reduced in resveratrol supplements-cardiac rehabilitation exercise training group in compared to control, resveratrol supplementation and rehabilitation exercise training groups (P˂0.05).
Conclusion: This study showed that combination of consuming resveratrol with rehabilitation exercise training in reducing some inflammatory factors was evaluated selectively, more effective than rehabilitation exercise training and resveratrol supplementation alone.
