Introduction: Considering the importance of diagnosing fetal distress and knowing diagnostic methods with minimum cost and time and high diagnostic value, this study was performed to evaluate the vibroacoustic stimulation test ( VAST) value in predicting fetal distress in women in active phase of labor, reffering to Motazedi hospital, Kermanshah, 2004.
Materials and Methods: This clinical trial study was carried out on women in active phase of labor (dilatation >3-4), full term, single fetus, cephalic presentation, without previous diseases and also abnormal fetus. At first FHR was monitored for 15 minutes, then vibroacoustic stimulation was done for 3 seconds using an artificial larynx of Seimens Servox with high - pitch intensity equal to 105 dB. Results were recorded as non reactive and reactive FHR ( twice 15 beats acceleration for 15 seconds). Other variables such as type of delivery, 1 and 5 minutes Apgar, meconium passing and nuch cord were documented. Data was analyzed by descriptive statistics and diagnostic value test.
Results: Age of women was 25.2 ±5.8, number of pregnancy 1.94 ± 1.33 and 51.8% of them had one pregnancy. FHR before VAST was 61.1% reactive and 26.3% suspicious and after VAST 60.8% reactive and 5.3% suspicious. In VAST method sensitivity, specificity and diagnostic value were 88.3%, 70% and 75.5% respectively and in nonVAST method 68.3%, 66.5%, 23.6%.
Conclusion: This study showed that VAST can assist to reduce suspicious cases of FHR.The prognostic value of VAST in predicting fetal distress was high. It is recommended to carry out further researches about duration and intensity of sound and using periodic FHR

Background: Radiotherapy is one of the cancer treatment methods. Prescribed dose for each fraction is considered based on radiosensitivity of tumoral and normal tissues. Viral agents are the effiectiv factors on tissue sensitivity. This research aimed to determine the effect of ionizing radiation of Cobal 60 on radiosensitivity of Hela cells infected with Measles virus. Methods and Materials: In this study, the radiosensitivity of Hela cells is investigated experimentally and qualitively. The cells have been cultivated in two groups (experimental and blank) and plating efficiency has been obtained. Then 100λ measles virus with serial dilution method was used to induce infection in different ratio for experimental group. After cell growth and passage, the two groups were irradiated with 2Gy gamma radiation of cobalt 60. Results: Results respectively indicated cell death increases up to 5-7%, 15-20% and 50-65%, after 2Gy irradiation by Co 60 for contaminating to Measles in low, moderate and high concentrations. Conclusion: Radiosensitivity of tumoral cells increases when they are infected by viral agent. The result in radiotherapy of cancers showed, in prescribing dose fraction non cancer disease should be considered.

Background: Endometriosis disease is considered as a common disease dependent on androgen hormones. Androgens have different effects on endometrial growth. Androgen receptor as a signal transduction pathway could have a key role in regulating the process. Over hundreds of mutations leading to resistance gene function in androgen receptor (AR) has been recorded. Among these, the seuaence of CAG repeat in exon 1 had the largest share of studies related to the disease. The aim of the present study was to investigate the relationship between the AR gene CAG repeat variations in Iranian women with endometriosis.

Materials and Methods: In this study, 100 women with endometriosis and 100 healthy women as controls were selected. Exon 1 was amplified using PCR. Products of PCR were studied to determine CAG repeat variation in acrylamide gels.

Results: The number of CAG repeats in each group was determined between 18-26 repeats (mean±standard, 18.35±3.3).

Conclusion: According to the results of this study, no significant differences were found between the two groups of healthy women and women with endometriosis. The number of CAG repeats in each group was determined between 18-26 repeats which indicates a lack of relationship between CAG repeat diversity and endometriosis. According to the information, this study was conducted on patients with endometriosis in iran for the first time, although studies with larger sample are needed.

Background and Aim This study aimed to investigate the clinical and laboratory characteristics of hydatid cyst disease in patients admitted to Imam Reza, Imam Hossein, and Bisotoon hospitals in Kermanshah City, Iran, from 2014 to 2018. 
Methods & Materials In this descriptive study, we studied and analyzed the medical records of 350 patients with hydatid cysts who were hospitalized and underwent surgical treatment in Kermanshah hospitals from 2014 to 2018. Also, the demographic characteristics of patients, including gender, age, occupation, place of residence, and affected organs, were extracted and recorded.
Ethical Considerations The Ethics Committee of Kermanshah University of Medical Sciences approved this study (Code: IR.KUMS.REC.1398.366).
Results In total, 350 patients with a Mean±SD age of 43.2±19.7 in women and 43.3±20.7 in men were admitted with a diagnosis of hydatid cyst. The highest and lowest prevalence of hydatid cysts were in the age groups of 41-50 (16.5%) years and 1-10 (4.8%) years, respectively. The prevalence was 181 (51.7%) in women and 169 (48.2%) in men. The organs mostly infected with hydatid cysts were the liver, lung, and brain, with 241 cases (68.8%), 55 (15.7%), and 24 (6.8%), respectively. 
Conclusion This study shows that hydatid cyst disease is an important disease, especially in rural areas of Kermanshah Province, Iran.
