Abstract
DNA analysis by flow cytometry is one of novel techniques recently introduce of utilize in routine clinical diagnosis laboratories , generally, there is an wverall agreement between DNA status and chromosomal content of cells, so with DNA analysis especially in neoplastic diseases, one coukd find the ploidy feature and number of cells which are in synthetic phase (S-phase fraction) and also cellular kinetics in select neoplasia, which are charactristics findings and factors that could be used as prognostic markers for predicting clinical behaviour and monitoring response to treatment protocol. In this study, we measured DNA content in eighty eight (88_ malignant lymphopreliferation diseases including 58 NHL and 30 HD diagnosed histopathologycally, by flow cytometry using Hedley method, Also immunohistochemical staining for proper immunophenotyping done in selected cases with ABC method with MoAb,s. Aneuploidy were 38% in NHL and 47% in HD patients. This occurance was unrelated to other parameters used as Age, tumor location and histologic subtypes. (P>0.05) S-phase fraction (SPF) measurement calculated as percentage of cellw in active phase and proligeration index determinations reveral higher frequency of SPF (PI) within Iranian patients rather than reported Western patients. This finding can account for lower survival rate and poor response to chemotherapy and (or radiotherapeutic regimen used in Iranian patients, but also other parameters in this regard also should be considered simultaneously.

Abstract
Introduction: The existence of acoustic trauma secondary to drill noise during chronic ear surgeries has not yet been clearly demonestrated. This investigation aims to document the hearing loss that occures in patients who underwent mastoidectomy.
Materials and Methods: Sixty-three (38 male and 25 female) consecutive patients (11-57 years) who underwent modified radical mastoidectomy were included. In a concurrent clinical trial design, we measured bone conduction thresholds before and after (1 week and 1 month) operation on both sides.
Bone conduction thresholds were assessed in 250, 500, 1000, 2000, 3000 and 4000 Hz frequencies.
Results: Paired-test results showed a satistically significant temporary (TTS) and permanent threshold shifts (PTS) were occured in the 2000-4000 Hz region for operated (on addition to 1000 Hz) and non-operated ears, but clinically PTSs were not remarkable and TTSs were important only for operated ear (P<0.05). The correlation between duration of noise exposure and magnitude of threshold shift was only significant in operated ear in 2000-4000 Hz region (P<0.05).
Conclusion: We could not demonestrate any permanent hearing loss caused by drill-generated noise, but resultant noise is able to produce TTS in the operated ear in 2000-4000 Hz region. We found poor relationship between duration of noise exposure and magnitude of threshold shifts.

Abstract
Introduction: Continues monitoring of oxygen saturation by pulse oximetery is known as a routine technique in critical care of patients. But previous researches showed some differences in its measurement according to probe placement.
Materials and Methods: In this cross sectional analytical study 36 admitted neonates below one months age were selected. Sampling method was convenience and sample size was estimated according to α=5% and β=20% .Samples oxygen saturation was measured three times by hand and foot pulse oximetery and direct method. Data was analyzed using paired t test.
Results: Analysis of results showed significantly dofference between both two pulse oximetery methods with arterial blood gas. Comparison of oximetery methods with direct one showed more accuracy of foot probe (p<0/05).
Conclusion: We concluded that pulse oximetery do not reliably predict changes in saO2 and also probe placement causes some differences in oximetery results.

Abstract
Introduction: Candidiasis is the second common cause of vulvovaginitis. We evaluate the frequency of species of Candida in vaginal candidiasis. Materials and Methods: In this cross-sectional anaiythical study, 220 patients with typic and nontypic signs and symptoms of vaginal Candidiasis were studied. Smear and culture were done. For positive culture, evaluation of germ tube, clamidospor production and carbohydrate assimilation and fermentation was done. Data was presented by descriptive statistics and analyzed using Chi square, Man-Whitney and Kolmogrov tests. Results: 40% of patients showed positive culture and smear. Frequancy of Candida Albicanse (42.03%), Dublininsis (29.5%), Glaberata (14.75%), Gilermondy (6.81%), Norvejensis (2.27%), Tropicalis (2.27%), and Kefayer (2.27%) were determined. There was no significant relationship between antibiotic and OCP consumption and type of identified Candida. Conclusion: Frequency of non Albicanse species is increasing. We suggest treatment based on culture and smear, because non Albicanse vaginitis usually is resistant to Azols.

Abstract
Introduction: Celiac disease (CD) or gluten-sensitive enteropathy is a malabsoption of nutrients due to hyoersesitivity of gluten. Some etiologic facrors are environmental, immunologic and genetic factors. The frequancy of Celiac disease is not studied in western regions of Iran, therefore this study is done to determine the frequancy of Celiac disease in general population of rural regions of Arak. Materials and Methods: This is a descriptive, cross-sectional study in which 700 people between 20-56 years old in rural regions of Arak were selected by multistage random sampling (364 male and 336 female). After completing questionnaires, blood samples were collected and serum IgA levels (to rule out IgA deficiency), and serum t-TG Ab were assessed. All cases that had positive serologies and those who had high clinical probability of having Celiac disease underwent second duodenal segment biopsy. Data was presented using mean, standard deviation and frequency distribution. Results: Serum IgA levels were normal in all samples. 8 cases were positive for t-TG Ab, 38 cases had high normal levels of t-TG Ab and the others had less than 6 Au/ml t-TG Ab. Only in patients with high normal serology, histology was positive. 1% (10 in 1000 people) of all studied subjects demonstrated intestinal lesions due to Celiac disease. Most of them were asymptomatic. Conclusion: CD frequency in rural regions of Arak in people between 20-65 years old was 10 among 1000 cases. This frequency is the same as studies done in northern and southern regions of Iran but was higher comparing to the other parts of the word. This amplifiles the importance of screening of CD in Iran. Also the sensitivity and specificity of t-TG Ab was found high because all cases with high normal levels of t-TG Ab were approved by histology.

Abstract
Background: The purpose of this study was to determine the effectiveness of dialectical behavior therapy in reducinng expulsive anger.
Materials and Methods: This is a pre-test and post-test semi-experimental study with control group. The study population included 32 patients with expulsive anger that reffered to Amir kabir remedial education center based on psychiatrist diagnosis and were randomely divided into case (dialectical behavior therapy) and control group. The case group was educated the dialectical behavior therapy skills for 16 sessions from 2 until 2.5 hours at teamly. To collect data, the patients filled Eysenk expulsive questionnaire before and after intervention. Considering no necessary assumptions were fulfilled to conduct the multivariate analysis of covariance and variance, so, the univariate analysis of variance was used.
Results: The results of variance analysis proved that dialectical behavior therapy significantly reduced expulsive angers.
Conclusion: With due attention to the results, it can be said that dialectical behavior therapy leads to reducing expulsive angers in treated patients, thus, this method can be included in interventional programs for target groups in psychotherapy centers. Aslo, it helps to improve the life of patients by reducing expulsive angers.

Abstract
Background and Aim: It is almost impossible to imagine life without electromagnetic waves. Such waves play a key role in the function of melatonin and create numerous diseases.
Methods & Materials: This descriptive-analytical study was conducted on 230 kV substations in Golestan Province, Iran in 2016. In total, 44 workers of electrical substations (the case group) and 23 workers of healthcare centers (the control group) with 24-hour shift works were enrolled in this study.
Ethical Considerations: This study was approved by the Ethics Committee of Shahid Beheshti University Medical Sciences( Code: IR.SBMU.THNS.REC.1395.9).
Results: The obtained data suggested that 100% of the electric field intensity and the magnetic flux density measured at the substations were within the permissible range of occupational exposure. The mean level of melatonin in the case group was lower than that in the control group; however, no significant difference was observed in this regard (P=0.761). Additionally, there was no significant difference between melatonin level and age (P=0.381), work experience (P=0.213), job groups (P=0.515), and employee activity area (P=0.482).
Conclusion: According to this study, no significant relationship was observed between electromagnetic waves and melatonin levels. Moreover, electromagnetic waves were within the permissible exposure. Thus, electromagnetic waves did not affect the level of melatonin hormone in male employees of 230 kV substations in Golestan Province. However, there was a decrease in the case group, compared to the controls. Therefore, definite comments require further investigation.

Abstract
Introduction: This research aimed to investigate the effectiveness of combined treatment based on virtual reality and mindfulness on cortisol levels in individuals with generalized anxiety disorder.
Methods: The study employed a semi-experimental design with a pre-test-post-test control group and a two-month follow-up period. The study population included all individuals with symptoms of generalized anxiety disorder who referred to the clinics of the Psychological Services Center and Counseling in Region 3, the Counseling and Psychological Services Center of Welfare in Region 6, and the Aryaz Counseling and Psychological Services of Region 6, Tehran, from April 2022 to the end of autumn 2022.
Results: The sample consisted of 30 individuals (10 males and 20 females) with generalized anxiety disorder, selected purposefully and randomly assigned to a treatment group based on virtual reality and mindfulness (15 individuals) and a control group (15 individuals). Pre-test, post-test, and follow-up cortisol levels were measured, and the Generalized Anxiety Disorder 7-item scale (GAD-7) was used as the entry criterion. Subsequently, the experimental group received an eight-session, 17-minute weekly treatment based on virtual reality and mindfulness. Participants in this group, while immersed in a virtual environment, watched 360-degree virtual reality videos, "Walking by the Beach" and "Pebbles in the Lake," accompanied by mindfulness audio contemplation, "Being Present and Breathing," and "Wise Mind," using a VR headset and VR-ARBOX. The control group received no treatment.
Conclusions: After completing the interventions, post-tests and two-month follow-ups were conducted. The data were analyzed using repeated measures analysis of variance (ANOVA) with SPSS23 software, revealing that the combined treatment based on virtual reality and mindfulness was effective in reducing cortisol levels. It is suggested that this combined method is used as a clinical intervention in order to reduce the level of anxiety and cortisol of people suffering from generalized anxiety disorder alone or along with other psychological and pharmaceutical interventions.
