The formation of society structures according to the structuralist view is created by the action between members of society and the production of similar signs in a system of signs. In relation to each other, these actions arrive at an "interactive order" from which the patterns, structures, and institutions of society emerge. Therefore, the process of community development takes place through these structures and institutions. Therefore, it is important to study the shift of the traditional and social structure of a society and its impact on development. The purpose of this study is to investigate the change in the social structure of Iran. The main question of the research is what effect the shift from traditional to postmodern structure has on the process of political development and the approach of international relations in Iran. The research hypothesis is that the change in social structure leads to the formation of structures and institutions of Iranian society that the concept of development emphasizes pluralism and human development rather than unity and economic development. Using a descriptive-analytical method and an integrated approach, as well as compiling a library, this study concludes that the change in the traditional structure that prevailed in the early Islamic Revolution and mainly in the form of specific roles of individuals and family system. He acknowledged that he portrayed the development of society as traditional and organic growth through the action of the postmodern structure, which takes place mainly in virtual human beings and in multiple and contrasting roles.

Recently, the radiation application research center for the atomic energy organization of Yazd (Iran) has developed a hydrogel dressing which was evaluated for quality and safety in 2008. Its efficacy for assisting in the wound healing process was approved for animal use, and its use has proven to be more effective than a related Syrian material..
We have already confirmed the safety and efficacy of Irgel use on mice (1, 2), so this study was conducted in order to further evaluate its effectiveness on human burn wounds, and to compare its efficacy with MaxGel, another hydrogel. A randomized clinical trial study was conducted to compare the efficacy of hydrogel produced by the radiation application research center (Yazd Branch) with MaxGel and routine dressing on burn repair in the Yazd Burn hospital..
In this study, 90 patients with second-degree burn injuries who were admitted to the Yazd Burn hospital were randomly divided into three equal groups. In the negative control group, the wounds were covered with sterile vaseline gauze followed by double sterile dry gauze and ultimately bandaged. In the test group, the wounds were covered by an Iranian hydrogel sheet (Irgel) instead of vaseline gauze, while in the positive control group, the wounds were covered by MaxGel instead of Irgel. At each visit (every other day), each dressing was renewed by its respective method and the wound area, pain score, and body temperature were recorded. At the beginning and at the end of the first and second week, five milliliters of venous blood were taken from all patients to evaluate hematologic parameters such as peripheral blood cell count, liver function, blood urea nitrogen, and creatinine..
Before the intervention, the extent of the burns and pain sensations were quite similar among the different groups, but at the second week, the burn areas and pain scores for the Irgel group were significantly less than those of the normal control and the positive control groups (P Based on our findings, both gels assist in the process of burn wound healing and pain reduction more effectively as compared with routine dressing. However, Irgel had better effects on wound healing and pain relief than MaxGel, which indicates a better quality of Irgel for this particular kind of treatment..

The learning and short memory are the most important parts of nerve system, and the interruption of these systems have always been very interested subject to the scientists and researchers. This study was designed to evaluate the effect of cinnamon extract on learning and short memory of mouse. This lab trial was done on twenty mice in laboratory. The study was carried out on four groups of mousse by using Shuttle Box equipment, the mice were divided into four groups and one group used as a reference and the other three groups were used as a result of study. The data was analyst by ANOVA and Scheffe methods using SPSS ver.14. After three days, mean score of learning was 67.9±7.7 that decreased to 49.9±8.8 in mice taking cinnamon with dose of 500 mg/kg (p<0.022). Also, mean score of short memory was 84.5±10.6 that decreased to 49.2±21.4 in mice taking cinnamon with dose of 500 mg/kg (p<0.024). This study showed that cinnamon will effectively decrease the learning and short memory parts of nerve system. It is recommended to set more studies with more samples to approve more reliable findings.

Nowadays herbal therapy for pain relevance is the matter of considerable propensity. Artemisia sieberi Besser is one of the herbal medication which has been consider as a pain reliever in Iranian traditional medicine, which needs further scientific investigations. In this study the antinociceptive effect of hydro alcoholic Artemisia sieberi Besser extract (AE) was assessed by using formalin test in mice. 42 male mice were divided into 7 groups. Interaperitoneal administration of distilled water to control group, vehicle to negative sham group, 1, 2 mg/kg morphine to positive sham groups and 40, 400, and 4000 mg/kg AE to test groups were performed. 25 µl of 2% formalin was then injected into the plantar surface of animal's hind limb and the animal's pain behavior for one hour was assessed. Mean pain scores in each five minute time block calculated for each animal were statistically analyzed. in acute phase mean pain score animals receiving 4000 mg/kg AE was significantly less than control groups p<0.05. the antinociceptive effect of AE was more prominent in the chronic phase so the analgesic effect of 4000 mg/kg AE was significantly more than 2 mg/kg. the data collected from this study indicates the analgesic effect of AE which is more significant in chronic phase and this effect may be due to anti-inflammatory ingredients in AE which needs to be more investigated.

Thyme is a plant in Labiata family which different species of this herb affects the menstrual cycle and therefore is avoided in high doses especially during the gestational period. Assessing the effect of thyme Decoction consumption in 2nd gestational week on placenta and fetus in rats. In this study 10 pregnant Wistar rats were randomly divided into 2 equal groups. Animals in test group received thyme Decoction in 2nd week of gestation. On 20th day of pregnancy, the placenta was removed and weighed. The number of live, dead or reabsorbed fetuses were recorded. All fetuses were weighed and stereomicroscopically examined for any morphological abnormalities in limbs, vertebral column, or head. Fetal height, fetal biparietal and placental diameters were also precisely measured. There were no significant differences in the number of live fetuses, between 2 groups. No dead or reabsorbed fetuses and no morphological abnormalities were observed in live fetuses. The live fetuses in both groups showed the same weight, height and biparietal diameter but the length of tail in test group was longer than control group (p<0.05). The placental weight was approximately identical in 2 groups, but its diameter in test group was smaller than the control group (p<0.05). According to our findings, although the thyme Decoction consumption in 2nd gestational week did not lead to any abortion, due to its adverse effect on tail length and placental diameter, it is recommended that the thyme consumption be with precaution especially during the pregnancy.

Estimating the width of maxillary incisors may be difficult when artificial teeth are selected for edentulous patients. This study examined the relationship between mesiodistal width of four maxillary incisors (WFMI) and inner canthal distance (ICD). Methods & Materials: In this descriptive study, 100 subjects (50 male and 50 female mean age 22.87 years) without facial and dental deformities were selected in this cross sectional study. WFMI and ICD were measured with Boley gauge. A mathematic formula to evaluate correlation between WFMI and ICD in 15 subjects has been used. (y = 1/784x-0/023x2) (y: mesiodistal width of four maxillary incisors, x: inner canthal distance). Then the difference between calculated size and real size of teeth was compared with paired t test. The mean of WFMI was 32.95±1.47mm and the mean of ICD was 31.9±1.83mm. In 70% of subjects, the difference between WFMI and ICD was less than 2mm. The correlation was r=0.345 (P=0). The calculated "model" for this relationship was y=1.784x – 0.023x2 (y: mesiodistal width of four maxillary incisors, x: inner canthal distance). 1- ICD is a good landmark for estimating WFMI. 2- The calculated model is competent and useful.
