Background&Objective: Up to seventh week of gestation, progesterone secreted from the ovary is necessary to preserve the pregnancy. In the ART cycles GnRH-a is prescribed and oocytes and granulosa cells or retrieved, both causes corpus luteum insufficiency, so corpus luteum should be supported the best way is progesterone prescription. In this research we compare intramuscular and intravaginal suppositoar forms of progesterone for preserve the pregnancy. Materials&Methods: A prospective cross sectional evaluation on 193 patients was designed. All of them were on IVF or ICSI cycles. The patients were randomly divided into two groups. Intramuscular progesterone was prescribed in 138 and intravaginal progesterone (supp cyclogest) in 54 patients. The outcome of pregnancy was analyzed using statistical trials including t-test and chi-squre. Results: The two groups were similar duo to age – the ethiology causes of infertility – the doses of proscribed HMG ampule – FSH titrago – the number and grade of transferred embryos. The day after HCG presciption until the end the seventh week in the first group (138 patients) intramuscular progestrone (50 mg /bid) and in the secound group (54 Patients) supp of cyclogest (400 mg / bid) was prescnbed. The rate of positive pregnancy test, abortion, successful poegnancy in this two groups were similar. Conclusion: Intramuscular or intravaginal progesterone for supporting corpus luteum in IVF or ICSI cycles has the same effect but the intramuscular route is cheaper.

Background&Objective: The breast cancer is the most common malignancy in women. The normal and malignant breast tissue are under the regulatory effects of esteroid hormones and growth factors including HER-2/neu. The purpose of this study, is to determine the expression of estrogene receptor (ER) progesterone receptor(PR) and HER-2/neu among Iranian women with invasive breast cancer. Materials&Methods: The study is descriptive and cross-sectional that was performed on 50 samples of patients with invasive breast cancer in Imam-Khomeini Hospital-Sari (2005-06). After preparing the samples four tissue sections from each sample was obtained then H&E and IHC staining were performed. Results: In our study, the patients were between 28-88 yrs, (mean:52/6). ER and PR and HER-2/neu were positive in 80%, 72% and 57.1% of cases, respectively. Concurrent positive ER and PR was 70%, meanwhile 62.9% of these patient were also positive for HER-2/neu. 20% of the cases showed negativity for both ER and PR and of these 83.4% were also negative for HER-2/neu. Conclusion: In our study ER expression by itself is equal to previous studies in textbooks but PR expression, HER-2/neu and concurrent expression of ER&PR are higher in our study. Interestingly HER-2/neu expression is near to what was previously proposed by Iranian Blood Transfusion Organization and Kerman University of Medical science. It seems that racial and geographic factors are contributed for these diffrences.

Background and Objective: Attention deficit hyperactivity disorder (ADHD) is the most common in psychology and Methylphenidate hydrochloride (MPH) is one of the most frequently prescribed pediatric medicine. This study was done to determine the effect of Methylphenidate hydrochloride on ovarian and pituitary gonadotropin hormone in peripubertal mice Materials and Methods: This experimental study was done on 40 preipubertal female mice (BALB/c) with three weeks age and approximate 12-15 gram. The mice were allocated randomly in one control and three experimental groups, designated as I, II and III. Animals in group I, II and III were received by gavage Methylphenidate hydrochloride with 2, 5 and 10 mg/kg body weight for six days, respectively. At the end of experiment body weight, serum estrogen, progesterone and pituitary gonadotropins were measured. Morphometric and histopathological evaluation of ovary were examined. Data were analyzed using SPSS-17, ANOVA and Tukey tests. Results: The body weight and ovary dimensions of animals in experimental groups were reduced significantly in comparison with control (P<0.05). Abnormal cells, structural alternations of granules cells and follicular growth abnormality were observed in experimental groups I and III in compare to control group. A significant reduction of estrogen, in group I, progesterone levels in group I and III were observed in comparison with the controls (P<0.05). Conclusion: This study showed that the Methylphenidate hydrochloride administration induces the reduction of body weight, ovary dimensions and hormones.

Background and Objective: Androgens are among the causative factors in preeclampsia. This study was done to compare the serum androgens and progesterone in preeclampsia and normal pregnancy. Materials and Methods: This case-control study was done on 30 preeclamptic and 30 healthy pregnant women in Gorgan, Iran. Higher or equal to 140/90 mmHg and proteinuria equal or more than +1 in dip stick test in the third trimester of pregnancy were considered as the diagnostic criteria of preeclampsia. Progesterone, free and total testosterone, and dehydroepiandrosterone sulphate (DHEA) were measured by ELISA method. Results: Total testosterone level was 1.8±0.3 ng/ml and 1.3±0.9 ng/ml in cases and controls, respectively. This difference was not significant. Progesterone was lower in cases (95±46.9 ng/ml) than in controls (165.4±75 ng/ml) (P<0.01). Free testosterone and DHEA were 5.6±2.3 ng/ml and 1±0.5 ng/ml in cases, respectively which was significantly higher than the controls (3.2±1.5 ng/ml and 0.7±0.4 ng/ml, respectively) (P<0.045). Conclusion: Serum level of free testosterone, DHEA and progesterone increased and reduced respectivley in preeclampsia.

Background and Objective: Sodium meta-bisulphite is used as a preservative in food and pharmaceutical industries. The aim of this study was to determine the effect of vitamin E on the improvement of sodium-meta bisulphite-induced complications on ovarian tissue and sex hormones in rats.
Methods: In this experimental study, 70 adult Wistar rats were randomly allocated into 7 groups including control, sham and interventional groups were received vitamin E (200 mg/kg/bw), sodium metabisulfite (520 mg/kg/bw), and sodium meta-bisulphite (520 mg/kg/bw) was combined with vitamin E in 50, 100 and 200 mg/kg/bw doses. Prescriptions were taken as gavage for 30 days. Blood samples were taken from animals to measure LH, FSH, estrogen and progesterone hormones. Ovaries were removed and follicles were counted after tissue sections.
Results: The concentration of estrogen hormones, progesterone, LH, FSH and number of ovarian follicles in the groups receiving sodium meta-bisulphite and vitamin E alone was significantly lower than control group (P<0.05). In animals treated with sodium meta-bisulphite and vitamin E at 100 and 200 mg/kg/bw, no significant difference was observed. However, in animals which were simultaneously treated with meta-bi-sulfite sodium and vitamin E at dose 100 and 200 mg/kg, in compared with the control group, significant improvement was not observed.
Conclusion: Sodium meta-bisulphite consumption with 50, 100 and 200 mg/kg body weight of vitamin E can reduce the effect of sodium meta-bisulphite on ovarian follicles and sex hormones.
