 Background & Objective: Poster is a non-projector, visual, graphic and printed medium that is applied in various cases specially in health education. On the other hand, one of the health education experts task is evaluation of educational methods and media. Since few studies were performed on effectiveness of posters on knowledge of people, this study was designed to determine the percentage of people who looked at the posters in health centers and also to determine the level of knowledge attained from these posters located in different places of health centers.

 Methods: This was a semi-experimental study. The population was people who referred to Shahid Gannadi health center. Samples were selected by simple random method. The data were collected by a questionnaire. The posters were fixed in three places during three different stages and the collected data were analyzed.

 Results: The findings showed that from among these subjects, 18.8% in the first stage, 20.8% in the second stage and 61.2% in third stage observed the fixed posters. The probability of the poster to be seen near the doorway and examination room was equal (Odds Ratio=0.9) whereas the probability of the same posters to be seen in waiting hall was 7 times as much as the previously mentioned locations. The ANOVA indicated no significant difference between demographic variables (age, sex, marital status, ets) of study subjects and their knowledge scores.

 Conclusions: The study showed that People paid very little attention to fixed poster. Therefore, regarding the role of posters in increasing the knowledge level, several strategies should be employed to make people pay more attention to these posters. Following the accepted standards in preparation and fixation of posters and preparation of three dimensional boards for the posters in health care centers are suggested.

  Background & Objective: It is now clear that the adult mammalian subventricular zone (SVZ) contains a population of neural stem cells (NSCs) that give rise to neurons and glia. Owing to their rarity, and a paucity of NSC-specific markers, the neurospher assay (NSA) is a common and selective method for isolating and understanding the biology of embryonic and adult neural stem cells. There are different methods for neurosphere growing from different regions of the CNS including Lateral ventricles. The objective of this study is introducing a new and effective strategy for more neurosphere firming from the SVZ of the adult mouse brain lateral ventricle using NSA.

 Methods: Two different methods were used in order to isolate and culture the SVZ of the lateral ventricles using NSA. In the first method (Ritze and Reynolds method) the rostral part of the SVZ of the lateral ventricles was dissected into single cell suspension and cultured using NSA. In the second method (vibratome resecting of the brain) after cutting the brain into 400 µm serial sections using a vibratom, the SVZ was microdissected from all sections of rostral part of lateral ventricle and cultured separately, using NSA. Primary neurospheres were counted seven days after plating. Then the mean numbers of neurospheres generated in two different methods were compared.

 Results: The mean number of neurospheres generated by sectioning method was much higher than the one generated using first method (P<0.0001). The distribution and frequency of neurosphere forming cells (or NSCs) is not the same along the antero-posterior axis of the rostral part of the lateral ventricle. The greatest frequency of neurosphere forming cells was detected in 0.74mm rostral to the bregma.

 Conclusion: Second section method, due to more neurosphere generation, in comparison with the first method is more appropriate and efficient for neurosphere forming from the SVZ of the lateral ventricle.

  Background & objectives : Today there is a significant progress in the treatment of female infertility but there is no main improvement for the rate of implantation and live birth. This is because of non-implantation and early abortion that lead to decrease the rate of live birth. Genital infections such as bacterial vaginosis are common cause of this problem.

  Distinction and treatment of bacterial vaginosis is easy and non-expensive. Treatment of bacterial vaginosis could results in improving the rate of implantation and then live birth.

  Methods: We considered 209 infertile women treated with ICSI (intra cytoplasmic sperm injection). This study was performed in infertility clinic of KOSAR hospital affiliated to Urmia University of Medical Sciences, Iran.

  Before transferring of embryo, a sample was taken from posterior culdesac secretions by sterile cotton swap and fixed it on lamella. Then bacterial vaginitis was graded by a pathologist. The relationship of bacterial vaginosis with implantation and early abortion was studied. Data were entered into SPSS software and analyzed by t-test and Chi-Square test. p<0.05 is considered statistically significant.

  Results: Bacterial vaginosis was significantly more frequent in patients with tubal and ovulatory disorder (p=0.013). In women undergoing ICSI, bacterial vaginosis was not associated with decreased conception rate (p=0.892) and with increased rate of early pregnancy loss (p=0.44).

  Conclution: Bacterial vaginosis is prevalent in women with infertility. It is also the most important cause of infertility in patients with tubal and ovulatory disorder. Bacterial vaginosis does not affect fertilization rate.

  Background & Objectives: Anatomical reconstruction of articular surface and restoration of walking ability without pain are the main goals of displaced intra-articular calcaneal fracture management, but treatment results are not always satisfied. This paper focused on comparison between open reduction and internal fixation using: A) auto graft B) bone cement, in patients with displaced intra-articular calcaneal fracture.

  Methods : This prospective comparative study of 44 patients with displaced intra-articular calcaneal fractures. Patients had been divided into 2 groups and then, they were operated by the standard protocol, including lateral approach, open reduction and internal fixation with reconstruction plate. Posterior facet was supported by autogenous bone graft in the first group (BG) and it was strengthened by bone cement in the second group (BC). Patients were followed up from the point of view of following surgical complications: 1- superficial infection, 2- wound dehiscence, 3- incisional site skin necrosis, 4- Sural nerve paresthesia, 5- osteomyelitis. Functional outcome were evaluated using calcaneal fracture scoring system and ankle-hind foot scaling system of AOFAS. The gathered data was analyzed in SPSS 16 software.

  Results : Of 44 included patients, 36 were male (81.8%) and eight were female (18.2%). The mean of age was 44.25± 11.34 (range: 16-69 yrs), and the mean of follow-up duration was 13.27±2.71 months (range: 9-18 months). The mean of operation time in second group (BC) (41.82min) was significantly lower than first group (BG), (p<0.001). Five patients (23%) from first group (BG) and only one patient (5%) from the second group (BC) showed surgical complications (p=0.079). There was no significant difference between the average score evaluated by calcaneal fracture scoring system and the average scale indicated by ankle-hind foot scaling system.

  Conclusion : Instead of autogenous bone graft, the use of bone cement decreases the duration of operation time and it seems to lead in less complications.

  Background & Objectives: I ntra-hippocampal adminestration of origanum (ORG) improves spatial learning of rats. T he aim of the present study was to investigate the possible mechanism for origanum extract on spatial learning and memory in the hippocampus.

  Methods : In this study 42 adult male Wistar rats were used . Animals were cannulated bilaterally in the posterior laterl of hippocampus. After the recovery period, the spatial learning and memory were assessed using Morris Water Maze (MWM). Saline, ORG (0.03μg/site) glutamate receptor antagonist MK801 (0.08, 0.2 and 0.4 μmol/site) and co-injected of MK + ORG was injected into the posterior lateral of hippocampus 20 minutes before the training and retrival sesions (for 5 consecutive days) (n=7).

  Results: The results showed that the intra-hippocampal injection of MK 801 significantly blocked the decreased distance and time of reaching (due to ORG injection) to find hidden platform of MWM (p<0.05). On the retrival tests, the average of time spent in the target area is reduced in the co-injected of MK801 + ORG group.

  Conclusion: The intra-hippocampal injection of aqueous extract oforiganum may improve working memory in rats through glutamate-dependent NMDA receptors.
