Background: Previous studies present various methods for prediction disease based on statistics or neural networks. These models use statistics and results from past procedures to provide prediction through probability analysis. Objective: In this article, the authors present a dynamic model aiming at predicting the treatment result of infertile women with the factor of polycystic ovary syndrome. Materials and Methods: For this purpose, the authors have divided the study population into five groups: women prone to infertility, PCOS women, infertile women undergoing the treatment with Clomiphene Citrate and Gonadotropin, infertile women under IVF treatment, and improved infertile women. Therefore, the authors modeled the disease in infertile women mathematically and indicated that the free equilibrium point was asymptotically stable. Also the possibility of other equilibrium point of the system has been studied. Results: The authors showed that this equilibrium point was marginally stable. Using Stoke’ s Theorem, the authors proved that the recurrence of the disease cycle with the factor of polycystic ovary syndrome was not intermittent in infertile women. They solved this model numerically using Rung-Kutta method and sketched the figures of the resulted solutions. Conclusion: It shows that with increasing age, the ovarian reserve is decreased and the treatment Clomiphene Citrate and Gonadotropin are not responsive, so IVF treatment is recommended in this group of patients considering the graphs of the model.

Background: Cyclophosphamide (CP) is a well-known alkylating anticancer agent used in the treatment of various malignant and non-malignant tumors. CP may also cause a variety of adverse effects, including reproductive toxicity. Amifostine is known as a cytoprotective drug having antioxidant properties. Objective: To evaluate the possible beneficial effects of amifostine on testicular toxicity induced by CP in rats. Materials and Methods: A total of 35 Sprague-Dawley rats were used in this experimental study. The CP group animals received a single dose of 200 mg/kg CP on Day 8 by intraperitoneal injection and were left untreated for the following seven days. The two remaining groups of animals were treated with 200 mg/kg/day amifostine (AMF 200) and 400 mg/kg/day amifostine (AMF 400) for seven days prior to and following a single intraperitoneal injection of CP. Morphometrical analysis and histological examination of testicular tissue were performed. Serum testosterone, luteinizing hormone, and follicle-stimulating hormone levels were measured in serum using commercial ELISA kits. The epidydimal sperm count was determined. Results: The tubular epithelial height in the testis was significantly higher in the AMF400 group compared to other groups (p < 0. 001). Animals in the AMF400 group showed minimal debris in the tubules, no Sertoli cell damage, and the Johnsen scores were slightly higher in the AMF400 group. The epididymal sperm count was significantly lower in the CP-administered animals compared to the control animals and was significantly higher in the AMF200 and AMF400 groups compared to the CP group (p = 0. 006, and p = 0. 019 respectively). Conclusion: Amifostine, at a dose of 400 mg/kg, may have a protective effect on testicular damage induced by CP in rats.

Background: Cervical dilation is indicated prior to performing various gynecological procedures. However, gynecologists are at times confronted with a stenotic or tight cervix, resistant to dilation. This can be problematic particularly when cervical ripening has not been attempted hours before the start of the procedure. Objective: The objective of this study is to investigate the efficacy of administration of hyoscine butylbromide for cervical dilation for immediate dilation of the tight or stenotic cervix. Materials and Methods: In this clinical trial study, a population of 40 women, aged 20-70 yr with stenotic cervix, evidenced by resistance to pass dilator #2 through their cervical canal were compared. Cervical patency was assessed 10 min following intracervical canal instillation of hyoscine butylbromide. Results: Cervical width of 57. 5% of patients became wider, as evidenced by passage of the number 4 Hegar dilator through the cervical canal without resistance. Independent T-tests did not reveal any statistically significant difference between the two groups based on their age. Fisher Exact test revealed a statistically significant difference between the two groups based on the prior route of delivery, with a more statistically significant response in patients who had vaginal deliveries. Conclusion: Intra-cervical canal instillation of hyoscine butylbromide is effective in immediate dilation of the tight or stenotic cervix during intra-uterine procedures.

Background: Monosodium glutamate (MSG) is used as a flavoring and food seasoning. Some studies have reported the oxidative effects of using this substance on various tissues. Objective: This study has investigated the effects of MSG and the protective effect of vitamin C (vit C) on apoptosis of testicular germ cells and biochemical factors. Materials and Methods: In this experimental study, 24 adult male Wistar rats were randomly divided into four groups: control (received distilled water), vit C group (150 mg/kg), experimental group 1 (MSG 3 gr/kg), experimental group 2 (MSG 3 gr/kg + vit C 150 mg/kg). The rats were gavaged for 30 days, and then were sacrificed, the right testis was isolated for biochemical examinations for the glutathione, malondialdehyde, and left testis used in histological experiments. Tunnel staining was used to determine the number of apoptotic cells. Results: The results showed that apoptotic cells in the MSG group had a significant increase compared to the control group (P = 0. 001), but the number of these cells in the MSG co-administered with vit C and vit C groups were significantly lower than the MSG group. Germinal epithelial thickness also decreased in MSG group compared to the control group. Conclusion: MSG can lead to increase apoptotic changes in the germinal epithelial of the testicle, and vit C as an antioxidant can modify the pathological and biochemical changes induced by MSG.

Background: Preeclampsia is one of the most common pregnancy complications, which is one of the major causes of fetal and maternal mortality. Objective: To compare the serum Brain Natriuretic Peptide (BNP) level in patients with severe preeclampsia and normal pregnancy and investigate associated cardiovascular complications. Materials and Methods: This case-control study was performed on 94 women with a singleton pregnancy (severe preeclampsia and normal pregnancy) at Imam Reza Hospital in Mashhad, Iran. The venous blood samples were collected to evaluate the serum BNP level. All patients were subjected to echocardiography performed by a single cardiologist. Results: The mean pro-BNP levels were 480. 36 ± 754. 52 and 67. 46 ± 106. 24 pg/dL in the severe preeclampsia and normal pregnancy patients, respectively (p < 0. 001). However, adjusted BNP for maternal and gestational age was not different in the two groups (ANCOVA, p = 0. 69). Furthermore, the two study groups showed no significant difference in terms of the cardiac parameters, including ejection fraction (EF), left ventricle end-diastolic and-systolic diameters (LVEDD and LVESD, respectively), tricuspid annular plane systolic excursion (TAPSE), and ratio of the early transmitral flow velocity to the early diastolic tissue velocity (E/Em). However, the serum BNP level showed a significant correlation with EF (r =-0. 39, p = 0. 008), TAPSE (r =-0. 47, p = 0. 001), and E/Em ratio (r = 0. 48, p = 0. 001) in patients with severe preeclampsia. Conclusion: It seems that BNP can be used as a predictor for some of the main cardiac functional indices (i. e., E/Em, EF, and TAPSE) in severe preeclampsia patients.

Background: Tamoxifen (TX) is widely used for the treatment of male factor and idiopathic infertility. It has been shown that TX induces sperm production and so improves male fertility. Objective: This study evaluated the effects of different doses of TX on the sperm parameters and chromatin quality in mice. Materials and Methods: In this research, 24 male NMRI mice were divided into three groups including group A: control animal receiving vehicle; group B: the group receiving basal diet and TX 0. 4 mg/kg/day; and group C: the group receiving basal diet and TX 0. 6 mg/kg/day for 35 days. Thereafter, epididymal spermatozoa were analyzed for standard parameters and nuclear chromatin quality using Aniline Blue (AB) and Toluidine Blue (TB) staining. Results: The results indicated that although the TX did not affect the sperm count, motility, and viability parameters, it could elevate the percentage of sperm cells with abnormal morphology and abnormal chromatin at both doses. In addition, in comparison with the control mice, a significant elevation was observed in spermatozoa with residual histones (assessed by AB staining) at high doses of TX. Conclusion: Our experimental data in mice suggested that the use of TX for treating male infertility might increase the rates of spermatozoa with abnormal chromatin in a dose-dependent manner.

Background: The menopausal symptoms are the most common problems in postmenopausal women. Due to the side effects of hormone replacement therapy, the use of medicinal herbs has increased for the treatment of menopausal symptoms. Objective: The aim of this study was to evaluate the effect of Saliva officinalis on the decreasing of the severity of the menopausal symptoms in postmenopausal women. Materials and Methods: The study was performed on 30 postmenopausal women aged 46– 58 yr referred to the healthcare center of Darab who experienced various degrees of postmenopausal symptoms. The severity of menopausal symptoms is recorded by a Menopause Rating Scale. Participants received a 100 mg capsule of sage extract daily for 4 wk. The severity of postmenopausal symptoms was compared before and after four weeks of the consumption of sage extract. Results: The results showed the severity of hot flashes, night sweats, panic, fatigue, and concentration had significant differences before and after the consumption of sage extract. Conclusion: It was concluded that Saliva officinalis were effective to change the severity of some of the menopausal symptoms in postmenopausal women.

Dear Editor The stressful experience of infertility is associated with a wide range of psychological damage (1), so infertility affects people’ s mental health and all aspects of an individual’ s life (2). Since women in the family are considered to be the main pillars of the community and they are also more vulnerable to illnesses, therefore consideration of their health is also very important (3). The objective of the current letter is investigating the mental health status of infertile women and its related factors as predictors of mental health in infertile women...
