Aloe vera plant beneficial effect on diabetes, burns, wounds, and gastrointestinal diseases has been proved. in this study, probably effect of aloe vera extract was investigated on serum tostestrone and gonadotropin levels in rat In this experimental study 35 adult male wistar rats with average weight of 200 ± 20 g were randomly divided into 5 groups, including control, sham and experimental groups 1, 2, 3, which received orally 50, 100, 200 mg /kg/bw aloe vera alcoholic extract respectively for 30 days. Rats anestized with eter, blood were taken from the heart, serum seperated and serum level hormones of LH, FSH and testosteron measured by radioemonoassay. The data analyzed based on ANOVA test. Results showed that serum levels of testosterone in the experimental group 2 (100 mg) and 3 (200 mg) compared with the control group decreased significantly (p <0.05). Also serum levels of LH and FSH hormones in the experimental group compared with the control group decreased. According to the results of this study, aloe vera plant alcoholic extract orally can decrease testosterone and gonadotropin secretion in the male rat.

Beauty is one of the important today’s people concerns; the facial wrinkles are including problems of beauty. Today, new non-invasive treatments have been used, such as using micro currents in treatment of wrinkles and skin renewal. This study aimed to determine the effect of Micro-Current's in the improvement of facial wrinkles. this before and after clinical trial, was performed on thirty subjects, with three requirements; haveing less than 45 years of age wrinkles and no skin problems. The cases were treated with micro current for twenty minutes on their face areas, for thirty consecutive sessions. Photos were taken from patients faces at the begining, end and one month after treatment. Three independent blinded reviwer has rated wrinkles in photos. Also patients has been assessed their treatment. The most improved rate was blong to forhead 18.37% in first step (befor and after treatment) and 21.18% in second step (after treatment and one month later) and the least improved rate was blong to nose and moth region; 7.61% in first step and 5.85% in second step. Micro current, improved facial wrinkles, this improvement was better in the frontal area comparing the nose and mouth. Also compareing the scores of photos, immediately after treatment and one month later shows that not only the effect of treatment was acceptable but also the recovery procedure continues after treatment. So, treatment satisfaction of patients was over 70%.

The purpose of this investigation was to study the effect of one session massage of the lower limb on flexibility, power and agility tests performance. For this purpose, 15 soccer players (Age 23.5±2.4 yrs, height 170.5±3.3 cm, weight 65.5±6.0 kg) selected randomly and participated in this study. The subjects performed the Sit and Reach, Toe-Touch, Vertical Jump and 4×9 tests in two stages before and after massage. They warm up themselves by 5-min jogging before testing. Massage was performed on lower limbs in both Petrissage and Tapotement methods for 15 min. Each test was performed three times and the best record was accepted. For determine the effect of massage on each tests performance, mean value in pre- and post-test was analyzed by paired t-test at p<0.05 level. Results showed a significant increase in flexibility tests records by 7.8±6.3% and 7.9±5.1% for Sit and Reach and Toe-Touch tests, respectively (p<0.05). But, the record of Vertical Jump and 4×9 tests have no significant change. Discussion& In general, if massage can improve muscle length without any adverse effects on power and agility muscle performance, so this hypothesis can be proposed that acute massage is a better technique for warming up before a power or agility event compare to other technique that reduce power and agility muscle performance.

Some Musculoskeletal disorders, fatigue and human errors rooted in the inadequate tools design. Appropriate design based on anthropometric data that must be done on the properties target population to be consistent. In our country due to lack of anthropometric database, more information is used from western countries. Project goal is physical dimensions of the Iranian people comparing with non-Iranian and ultimately producing based on our body dimensions that Iranian expert use of this internal standards to design and manufacture all our tools and equipment. Cross-sectional study was prospective and observational method that was done. In this Study, 384 female and 384 male students from medical Sciences University in Isfahan were randomly selected. 30 anthropometric variables were measured by anthropometer, calipers and balance. This data were analyzed by spss software version 11.5 and index percentile was calculated. Percentile obtained in America and Britain compared with the standard and the percentage of difference between them was determined. The statistical anthropometric percentile as a database for both genders was found. This study compared British and American standards showed the most significant difference between anthropometric variables of Iranian and non-Iranian people. This study shows that Iranian body dimensions are different from non Iranian persons. Therefore we can’t use other countries standard to design tools and devices for Iranian persons. These results can be used as one anthropometric information bank based on national standards.

Cesarean Section delivery is one of index in mother,s health planning.High rates of elective cesarean is alert for our country health management and mothers need to more consultion about the complication of C/S. Because of the knowledge of pregnant women is important about the preferable delivery method,the objective of this study is determine the knowledge of cesarean complication.

This cross-sectional study was done in 1388.360women pregnant (third trimester)were recruited randomly from iran southwest hospitals. Data were analyzed using spss 11.5 version of software. According to their knowledge score, subject knowledge level was classiefied in to three levels,good knowledge level (score 14-18),mid knowledge level (score 9-13) or poor knowledge level(score 0-8)

The levels of knowledge in the pregnant women about complication of cesarean in 43.2% were good,in 38.4%were average and in 18.4% were bad.68.1% people in research was to select vaginal delivery (NVD) and (31.9%)of them to C/S.There is a significant association between the knowledge of pregnant women about complication of cesarean and choosing of type of delivery(p=0/04).The main cause of women toward C/S was fear of labor pain and easy of that(43/3%).

The level of knowledge about complications of cesarean in the women were good and according to the result of this study fear of labor pain is important cause for choose of C/S in pregnant women,It is recommended that painlees delivery will be assembled in jahrom hospital and most effort should be for first C/S. We wish this study be process small for allocate mathernal health and hygiene.

Family physician program carried out in 2005 year in villages and cities with populations under 20000, one of the objectives of this program is priority to health vision oriented treatment instead of being oriented in providing service and avoids wasting resources in the field of health, The aim of this study Relationship between Knowledge of Rural People with Choice Reasons Family Physician Program towards Villager Population in Shahr-e-kord In this descriptive analytic survey, 1100 individuals under the program of rural family physician in Shahrekord were selected by multi-stage cluster random method.

The effect of aerobic exercise on the blood coagulation system as a risk factor for coronary disease is still controversial. This study aimed to investigate the effect of a session of moderate aerobic exercise on some of the blood coagulation factors in the young girls. This interventional study was conducted on 11 healthy female volunteers aged 21 to 24 years, who had taken no systematic physical exercise for one year. This study was approved by the Ethics Committee of Kerman University of Medical Sciences. The performed protocol comprised 30 minutes of running with 70-75% intensity of maximal heart rate reserved. Every volunteer donated blood for 3 times (before, immediately after and 30 minutes after the intervention), and the coagulation factors of Platelet count, Mean Platelet Volume, PT, aPTT, Fibrinogen and Factor VIII of plasma were measured. The data were analyzed using the repeated measures ANOVA. Immediately after a session of aerobic exercise, the platelet count and factor VIII increased about 23% (P= 0.001) and 75% (P=0.004), respectively while aPTT decreased about 8% (P= 0.007). PT showed a delayed increase observed 30 minutes after the exercise (P< 0.001). The results revealed that physical exercise, even with moderate intensity, activates some of blood coagulation markers and can lead to further side effects and probably a longer recovery. These findings would be helpful in adjusting the exercise intensity for the sedentary people, especially at the beginning of the training course

Chronic pain is one of the most prevalent reasons of referral to health centers. Cognitive Behavioral Therapy (CBT) has been shown to be an effective treatment for chronic pain. The current study was conducted to evaluate the efficacy of Cognitive Behavioral Therapy in patients with chronic musculoskeletal pain. CBT was evaluated in 8 sessions of up to 50 minutes in 4 patients with chronic musculoskeletal pain. A multiple baseline with a follow up of 1 month was used. Patients were randomly allocated to baselines and outcome and assessed via Beck Depression Inventory (BDI), Pain Catastrophizing Scale (PCS), Visual Analogue Scale (VAS) and Cognitive Coping Strategies Inventory (CCSI). Results showed that Cognitive Behavioral Therapy was effective in reduction of depression, pain Catastrophzing and pain intensity, and improvement of coping strategies. These effects were maintained to some extent in the follow up. Psychological as well as medical treatment can be helpful in the patients with chronic pain.
