Abstract
This study has been performed on show the incidence of sensory neural hearing loss (SNHL) in patients with chronic Otitis Media (COM) and it’s different parameters. 207 patients with persistent or previous otorrhea have been examined. 70 patients had bilateral otorrhea and 137 patients had unilateral problem so overall 277 ears are evaluated. The BC greater than 15 dB without carhartnotch was the basis for diagnosis of SNHL. 66 patients had SNHL and of them 26 cases were bilateral so total number of ears with SNHL were 92 (The incidence of SNHL was 32.2%). 3 cases were due to other causes like TB (1 case) RM fistula (1 case) and squamous cell carcinoma (SCC) of middle ear (1 case). About 90.3% of cases had down slooping high frequency SNHL in their audiogram. In 47.6% of the ears with granulation tissue and cholesteatoma had SNHL while 28.7% of cases with chronic perforation revealed SNHL. Analysis of this study showed that there is a probability of increased SNHL during old ages the cases of prolonged and persisted otorrhea also revealed a higher incidence of SNHL. We didn’t disclose correlation between age and severity of SNHL.

Abstract
Background and Objective: The growing development progress of electronic industries and the increasing use of electrical appliances have led to higher rate of exposure of people to electromagnetic field (EMF). Thus, in this study we investigated the effect of EMF on morphometric indices of epididymis and vas deferen in mice. Materials and Methods: In this experimental study, 30 BALB/c male mice were selected and divided into three control, sham and experimental groups. Experimental group were exposed to 50 Hz, 0.5 mT EMF for 4 hours per days, 6 days per week for 8 weeks while the animal in control and sham groups were not exposed to EMF. After the exposure period, the mice were dissected and left testis was removed and weighted. Samples of epididymis and vas deferen in all groups were taken and were processed for routine light microscopic studies. The diameters of epididymis and vas deferen and the height of epithelial cells in all groups were compared using ANOVA and Tukey tests. Results: The mean diameter of epididymis in EMF group significantly decreased compared to the control group (P<0.05). The mean diameter of vas deferen, the height of epithelial cells in epididymis and vas deferen in EMF groups significantly decreased compared to the control and sham groups (P<0.05). In addition, the weight of testes in EMF group significantly decreased compared to the control and sham groups (P<0.05). Conclusion: This study showed that the EMF exposure for long time could have hazard effect for the male reproductive system by decreasing the diameter of reproductive ducts, the length of epithelial cells and weight of testes.

Abstract
Multiple sclerosis (MS) is a chronic and multiphasic autoimmune disease which affecting the nervous system. Recently, neurotrophic factor secreting cells have been proposed as one of the best sources for cell therapy in MS disease. Therefore, this review study was done with aimed to introduce neurotrophic factor secreting cells and the role of neurotrophic factors in the treatment of MS. The present study, based on the Systematic Review and using multiple sclerosis, neurotrophin and cell therapy keywords, 98 articles were searched from various databases including Pubmed, SID, Springer, SinceDirect Magiran, Web of Sciences and the Google Scholar. After removing irrelevant and repetitive articles, 50 articles were selected. The results of these studies showed that cell-based therapies in MS have been designed with the aim of replacing destroyed cells or with the goal of neuronal support using neural growth factors. Neurotrophic factors secreting cells with the ability to migrate to neurological lesions and secretion of neurotrophic factors can play a major role in supporting neural tissue and preventing its destruction. These factors, through tyrosine kinase receptors, have a variety of effects on the development and proper functioning of neurons. On conclusion, neurotrophic factor secreting cells due to the secretion of a wide range of neural growth factors which required for neural development might be one of the ideal cell sources for cell-based therapy in MS disease.

Abstract
Background and Objective: The incidence of tuberculosis in Golestan province in northern Iran is 26.7 cases in 100000 persons. Lack of energy and nutrients is one of the reasons for the increased risk of tuberculosis. Malnutrition is an important cause of high mortality in the Tuberculosis (TB) population. With decreasing level of visceral proteins, anthropometric indices, and micronutrients increase the risk of mortality. This study was performed to determine the status of nutritional status of patients with Tuberculosis in Gonbad-e-Kavous, north of Iran during 2014.
Methods: This descriptive-analytical study was performed on 45 pulmonary tuberculosis patients with mean age of 57±20 living in Gonbad city, north of Iran during 2014. Demographic information and history of tuberculosis, body mass index, albumin, hemoglobin, total protein and blood cell count and food intake were recorded for each patient.
Results: 58% of patients were women. 52% of patient was resident in rural area. There was a significant difference in terms of body mass index and previous history of tuberculosis in patients with different disease intensities. Among patients with different disease intensities, the difference in the distribution of anemia severity was not significant. There was no significant difference between the two sexes in terms of disease severity distribution. According to the fitted regression model, the age variable, even in the presence of other variables, had a significant effect on disease severity (P<0.05).
Conclusion: With increasing disease severity, patients' BMI decreases and the severity of malnutrition and anemia increases. The severity of the disease increases with age. Tuberculosis patients need nutritional support.

Abstract
Background and Objective: Restrictions imposed during the coronavirus disease 2019 (COVID-19) pandemic led to a decrease in physical activity levels across various age groups, particularly among students. This study aimed to determine the effect of eight weeks of corrective exercises on musculoskeletal pain levels in 13-15-year-old students.
Methods: This clinical trial was conducted on 101 students (44 girls and 57 boys) aged 13 to 15 experiencing musculoskeletal pain in various body parts in Bandar Mahshahr, Khuzestan Province, during the second half of the academic year 2021-2022. Participants were selected based on the Adolescent Nordic Musculoskeletal Questionnaire (NMQ), considering only the first question regarding the presence or absence of pain in each of the nine body regions (neck, shoulder, elbow, hand, upper back, lower back, pelvis, knee, and ankle) in the past seven days. A score of 1 was assigned to the presence of pain and 0 to the absence of pain. Participants were randomly assigned to two groups of 60: A control group and an intervention group. The intervention group performed corrective exercises at home for eight weeks, with three sessions per week, each lasting 40 minutes. No intervention was provided to the control group. Musculoskeletal pain levels in the neck, shoulder, upper back, elbow-arm, wrist, lower back, knee, and ankle were then compared in the pre-test, post-test, and follow-up.
Results: The mean and standard deviation of the total pain scores for the intervention and control groups were 1.32±0.41 and 1.33±0.46 in the pre-test, 1.01±0.08 and 1.34±0.46 at the post-test, and 1.17±0.36 and 1.11±0.31 at follow-up, respectively. Results revealed that eight weeks of corrective exercises significantly reduced musculoskeletal pain levels in the students’ neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, pelvis, and thigh (P<0.05); however, this improvement was not sustained at the follow-up.
Conclusion: Performing corrective exercises reduced musculoskeletal pain levels in the neck, shoulder, upper and lower back, elbow, knee, wrist, ankle, and pelvis and thigh of 13-15-year-old students; however, the benefits were not sustained when the exercises were stopped.
