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: Cardiac arrest is responsible for half of the death cases, which is preventable in rapid and effective cardiopulmonary resuscitation (CPR). During the last years, a great amount of progress has occurred in this field, but there is still a lack of enough data for CPR. The aim of this study was to assess and compare the survival rate of patients undergoing CPR in two university hospitals in Tehran, Iran. Materials and Methods: In this retrospective analytical study, the survival rate of 178 patients undergoing CPR in the emergency department of two university hospitals (Taleghani and Shaheed Modarres) were assessed and compared during 2005. The related variables including the time delay for CPR, the time length for CPR and the outcome of CPR were analyzed. Results: 24 hours after the cardiac arrest, 7 cases of 54 (13%) survived in Taleghani hospital and 33 of 124 (26.6%) survived in Shaheed Modarres hospital (P<0.05). Conclusion: This study showed that the rate of short term survival of patients after CPR is similar to other parts of country but lower than the other parts of the world.

Background and Objective: Headache is one the most common compliant of patients and has different causes and the migraine and tension headaches are common. Personality is characteristics forming an individual distinctive manner. This study aimed to determine the frequency and association of different types of personality characteristics in patients with migraine and tension headaches. Materials and Methods: This descriptive-analytic study was done on 160 (12 male and 148 female) subjects with chief complaint of headache whome referred to 5th Azar clinics of Gorgan, Iran during 2007-08. Subjects were selected by simple random sampling and were examined by either a neurologist or psychiatrist patient with diagnosis migraine either of or tension headache were included. Selected patients evaluated by short form of Minnesota Multiphasic Personality Inventory (MMPI). Data were analyzed using SPSS-13 and Chi-Square test. Results: The mean age was 11.18±33.29 in women and 34.33±13.7 in men. 96 patients (60%) had tension headache and 64 (41.2%) had migraine. In tension headache, depressed personality (43.8%) and hysterical personality (16.4%) were more common but in migraine headache, depressed personality (48.9%) and paranoid personality (20%) were common but this difference was not significant. Conclusion: This study showed that there is no relation between personality characteristics with tension headach and migraine.

Background and Objective: The flowers of Citrus aurantium L. are traditionally used in the treatment of neurological disorders such as seizures, epilepsy and neurasthenia. With regard to the importance of nausea and vomiting and effects of strengthening the stomach of Citrus aurantium L. extract, this study, was done to determine the antiemetic effect of the metabolic, aesthetic and aqueous extract of flowers of Citrus aurantium L. in young chickens.

Methods: In this experimental study, induction of emesis was performed in 138 young chickens
(23 groups, n=6) using copper sulfate (60 mg/kg, orally) and ipecac (600 mg/kg, orally). The aqueous, methanolic and acetonic extract at doses of 50, 100 and 250 mg/kg/bw were injected intraperitoneally (i.p.) and metoclopramide (as positive control). The number of nausea was recorded 50 and 20 minutes after copper sulfate and ipecac administration, respectively.

Results: Our results showed that all kind of extract at doses of 100 and 250 mg/kg significantly inhibited copper sulfate and ipecac induced–emesis that showed better effect than metoclopramide. Also, comparison of antiemetic effect of different extract revealed that methanolic, aqueous and acetonic had better effect on prevention of nausea, respectively in comparision with metoclopramide.

Conclusion: All kinds of Citrus aurantium (Methanolic, Aesthetic and Aqueous) showed antiemetic effect due to copper sulfate and ipecac dose dependly in Young chickenin in comparision with metoclopramide.

Background and Objective: The anti inflammatory, analgesic, antioxidant of Sambucus ebulus L. have been reported in several studies. This study was done to assess the repelling property of the methalonic and hexanic extracts of Sambucus ebulus L. against the Culex pipiens.

Methods: In this experimental study, Sambucus ebulus L. collected from the natural inhabitants of Mazandran province in northern Iran. Methalonic and hexanic extraction were provided from the leaf and fruit of Sambucus ebulus L. Concentration of 50 mg/kg, 100 mg/kg and 250 mg/kg was prepared. 0.4 ml of the extract prepared and was spreed on the albino skin area of 4×6 cm2. After 30 minutes the number of the mosquito (Culex pipiens) bites on the skin was recorded. N, Ndiethyl-3 methyl benzamide was considered as positive control.

Results: The highest repelling property of the Sambucus ebulus L. belonged to the concentration of
250 mg/kg of leaf and fruit extraction. The highest repelling effect was 80% and 66.8% for leaf methalonic and hexanic extract, respectively. The highest repelling effect was 84% and 72% for fruit metalonic and hexanic extract, respectively (P<0.05).

Conclusion: The methalonic extract of Sambucus ebulus L. had higher repelling efficiency compared to the hexanic extract. The fruit extract also had better effect than the leaf extract.

Background and Objective: The synthesis of uncoupling protein 1 (UCP1) in adipose tissue plays an important role in providing resistance and prevention of fat accumulation, weight gain and obesity. This study was done to evaluate the effect of eight weeks aerobic training with moderate and high intensities on serum levels of Irisin and UCP1 white adipose tissue in obese male rats.
Methods: In this experimental study, 24 adult obese male Wistar rats (weight: 250 to 300 gr, BMI>30g/cm2) were randomly assigned into three groups including moderate aerobic training intensity, high intensity aerobic training and control group. The aerobic exercise training was included 8 weeks (5 sessions/per-week for 60 min per session). All training groups carried out aerobic training with 28 m/min (moderate intensity), aerobic training with 34 m/min (high intensity) on treadmill. 48 hours after the training period, the level of UCP1 and Irisin protein was measured.
Results: The level of UCP-1 in adipose tissue and serum Irisin in both aerobic training intensities increased compared to control group, but this increase only in aerobic training group with a moderate intensity was singnificant (p<0.05).
Conclusion: Eight weeks aerobic training with moderate intensity leads to increase of UCP-1 in adipose tissue and Irisin levels.

Background and Objective: Understanding the cellular signaling mechanisms involved in muscle hypertrophy is considered a scientific challenge. Mammalian target of rapamycin (mTOR) is one of the regulatory factors in this process that increases protein synthesis in skeletal muscle through phosphorylation. This study aimed to determine the effect of six weeks of high-intensity interval training (HIIT) on phosphorylated mTOR protein in the quadriceps muscles of adult male Wistar rats.
Methods: In this experimental study, 16 adult male Wistar rats (six weeks old and weighing an average of 190.93±4.97g) were used. The animals were randomly divided into two groups of control and training (n=8). The training group underwent six weeks of HIIT on a treadmill, with five sessions per week. The load was increased during the six weeks from repeating the interval of 30 meters per minute for 30 seconds in the first sessions to eleven repetitions of the interval of 35 meters per minute for 30 seconds at the end of the sixth week, with rest intervals between the intervals at a speed of 13 meters per minute for 60 seconds. The control group did not undergo any training. The mice were anesthetized, and the Vastus lateralis of the quadriceps muscle was extracted. The level of phosphorylated mTOR protein in the quadriceps muscle was measured using the immunohistochemical method.
Results: HIIT significantly increased the levels of mTOR phosphorylation protein in male Wistar quadriceps femoris muscle compared to the control group (P<0.05).
Conclusion: Interval activity can have a positive effect on muscle hypertrophy through mTOR.
