Background: Primary dysmenorrhea is one of the most prevalent disorders in women which results in their decreased efficacy. The aim of this study is to evaluate the effect of pressure on the third liver point on involved liver channel symptoms in patients with primary dysmenorrhea. Materials and Methods: This clinical trial was conducted on 194 students that met the inclusion criteria. In the first cycle, symptoms of involved liver channel were identified. Accordingly, participants were randomly allotted to either treatment or control groups. In the second, third and fourth cycles, acupressure was applied to the third liver point and placebo point for 20 minutes 3-7 days before menstruation. With bleeding in the fourth cycle, the symptoms of involved liver channel were determined. Results: In the first cycle, there were no significant differences in symptoms of involved liver channel between the two groups however, in the fourth cycle, the results of Chi2 test showed significant differences between the two groups in all symptoms of involved liver channel except the tongue with red spots (p<0.05). In the treatment group, a comparison of the first and the fourth cycle revealed significant differences in all symptoms of involved liver channel except for tongue with red spots (p<0.05). Conclusion: In this study, applying pressure to the third liver point was effective in the improvement of the majority of involved liver channel symptoms therefore, acupressure is suggested as a practical, effective, non-expensive, and available method in the treatment of primary dysmenorrhea.

Background: Noticing the fact that graft survival rate of kidney transplantation from live donors is more than deceased donors, this study was conducted to determine the relationship between the graft survival rate of renal transplantation and the donor source in patients transplanted from March 1999 to March 2009 in Namazi Hospital Transplantation Center of Shiraz. Materials and Methods: In this retrospective cohort study which was designed to determine the relationship between graft survival of kidney transplantation and the donor source (related live donor, unrelated live donor, and deceased donor) in 1356 patients who were transplanted in Shiraz Transplant Center, Namazi Hospital. Kaplan-Meier method was used to determine the survival rate, log-rank test was used to compare survival curves and Cox regression model was used for ruling out the intervening factors. Results: Five-year graft survival rates of renal transplantation from related, unrelated, and deceased donors were 92.4, 92.6 and 82.1%, respectively. Also, a significant relationship was seen between donor source and survival rate of the renal allograft (P>0.001). Conclusion: The findings of this study transplanted patients with kidneys from living donors (related or unrelated) have a higher graft survival rate compared with deceased donors.

Background: Considering that pre-diabetes is one of disorders that increases developing of diabetes, this study was performed to investigate the effect of L-Arginine supplementation on antioxidant enzyme activity, total antioxidant capacity, and body composition in patients with pre-diabetes.

Materials and Methods: A double-blinded randomized clinical trial was performed on 46 pre-diabetic patients. Patients in intervention (n=23) and  placebo groups received  3g/day L-arginine and placebo (three 1gr L-arginine capsules), respectively for 8 weeks. Anthropometric, body composition, and dietary intake assessments, and also biochemical tests were done at baseline and end of study. Total Antioxidant Capacity (TAC), glutathione peroxidase enzyme and superoxide dismutase activity were measured. Paired t-test, independent t-test and ANOVA were used to analyze quantitative variables.

Results: Thirty eight patients (19 subjects in each group) completed the study. After adjusting confounding factors, no significant difference in body composition, anthropometric indices and dietary intake was observed at the end of study (p<0.05 in all factors), but a significant difference in TAC level was observed in the intervention group at the end of study (p<0.001).

Conclusion: Supplemenation with 3gr/day L-arginine for 8 weeks led to raised serum TAC level without changes in body composition in pre-diabetic patients.

Abstract
Introduction: Resistance training (RT) is an important part of athletes' preparation exercises with the aim of strengthening physical fitness, creating neuro-muscular adaptations and improving sports performance. The aim of this study was to investigate the effect of resistance training with weight on NCV of tibial and peroneal nerves, muscle strength, agility, flexibility and performance of half-back, half-turn and angel balance skills in seven- to ten-year-old gymnasts.
Methods: In this semi-experimental study, 24 children with two years of experience in gymnastics (age: 8.5±1.5 years, weight: 32.10±9.40 kg, height: 135±13 cm) voluntarily Participated. Subjects were randomly divided into two groups including gymnastics training and gymnastics training + resistance training with weights. And they trained for 10 weeks. During the research, one group did general gymnastics exercises, and the other group did resistance training with weights three times a week in addition to gymnastics exercises. Before and after the exercises, NCV test, Sargent's jump muscle power tests, agility of 9x4m back-and-forth run, Wells' flexibility, and performing half-back, half-turn and balance skills of Angel were performed. Independent t-test was used to analyze the data. And a significance level of P<0.05 was considered.
Results: The results showed that the NCV in the tibial and peroneal nerves increased significantly in the weight resistance training group compared to the general gymnastics training group. Also, muscle strength in Sargent's jump, agility in 4x9m back and forth running, and the performance of half-back and half-turn skills increased significantly (P<0.05). However, no significant change was observed in the flexibility with the Wells test (P=0.870) and execution of Angel's balance skill (P=0.552).
conclusion: 10 weeks of resistance training with weights significantly increases neuromuscular adaptations, NCV, muscle power, agility, and implementation of half-back and half-varus skills in gymnast children. Therefore, it is suggested to use resistance exercises with weights to improve the performance of children athletes in the field of gymnastics and fields where nerve conduction speed, muscle power and agility are effective in the success of athletes.
