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

Introduction: Adenosarcoma is a rare uterine tumor composed of benign epithelial and malignant stromal elements. In 20% of cases stroma contains heterologous elements (usually from stratified muscle type). Association between Tamoxifen usage (exogenous strogen) or ovarian thecoma (endogenous strogen) and occurance of this tumor has been reported. This is a case report of a uterine Adenosarcoma. Case: The patient was a 45 years old woman with history of 16 years OCP use who was admitted with a uterine mass and undergone total hysterectomy. Microscopic assessment of slides, stained by H&A, was indicator of Adenosarcoma with cartilage heterologous elements. Conclusion: Uterine Adenosarcoma is a rare tumor. Although there is a few reports of cartilage heterologous elements in uterine Adenosarcoma, this case had multiple cartilage points in stroma. Also in this case, the coexistance of this tumor with long- term OCP use was considerable.

Introduction: Nowadays, the attention of researchers has been focused on natural medicine in order to avoid the detrimental side effects of chemical drugs. In this study we assessed the effect of root extract of Tagetes minuta against HSV-1 and HSV-2. Materials and Methods: This research is an experimental study. Root extract of Tagetes minuta was obtained with 70% ethanol by maceration. Vero cells were grown in DMEM containing 5% fetal bovine serum. Serial dilutions of extracted suspension (1/10, 1/20, 1/40, 1/80, 1/160) were incubated by the exact titer of viruses and monitored for antiviral activity of extract. Data was analyzed using Doncan test. Results: Root extract obtained from Tagetes minuta significantly has antiviral activity against HSV-1 and HSV-2. This extract has more effect on HSV-2 than HSV-1. This study indicates that antiviral activity of the extract varies between different concentrations and the optimum antiviral activity on both viruses was obtained using 1/10 concentration. Conclusion:The results of this investigation showed that root extract of Tagetes minuta have good antiviral potenoial against HSV-1 and HSV-2, a good source of drug for treatment of diseases due to HSV-1 and HSV-2.

Background: The importance of VP2 protein of canine parvovirus to bind to human cancer cells and to detect the virus in veterinary detection kits has motivated a lot of research on the production of this protein. In this project, a surface gene of canine parvovirus (VP2) was cloned and expressed in a prokaryotic vector system and its expression was optimized in a specific cell-free prokaryotic expression system. Materials and Methods: In this experimental study, plasmid pET-21aVP2 was constructed by cloning the PCR product of VP2 gene of canine parvovirus into the plasmid expression pET-21a vector. The best sequence was analyzed through PCR and it was followed by confirmation with sequencing and restriction digestion. To produce VP2 protein, plasmid pET-21aVP2 was transferred into Escherichia coli, Rosetta (DE3) strain, and the expression of this protein was induced by IPTG. The production of VP2 protein in both systems was evaluated using SDS PAGE technique. The expressed protein was checked with monoclonal antibody against VP2 protein by Western blotting technique. Results: Successful cloning of VP2 protein was confirmed by enzymatic digestion and sequencing. The expression of VP2 protein in bacterial and cell-free prokaryotic systems was verified by SDS PAGE and the specific band in Western blotting also confirmed the VP2 protein. Conclusion: The results of this study showed that VP2 gene was amplified in the cloning phases and it was successfully cloned in the expression vector. Protein expression was confirmed in both bacterial and cell-free prokaryotic systems.
