Abstract
Background: The male antifertility activity of Gossypol, the active ingredient of cotton seed, inspired the idea for development of an agent with male contraceptive activity. The result of subsequent studies lead to the discovery of several class of compounds with antifertility activity.
In this study the antifertility activity of iso-Propyl and iso-Butyl derivatives of dihydropridine were evaluated.
Methods: The two aforementioned compounds were administered subcutaneously in (10 mg/kg/day) dose to male rats. The animals were treated and kept according to the TUMS committee recommendations on ethical and animal maintenance considerations. Sixty days after the first injection the following fertility and histological indices were evaluated, animal’s body weight difference (B.W.D), sperms motility, sperm viability, ESR (epididymal sperm reserve), DSP (daily sperm production), serum testosterone concentration, fertility index, GSI (gonado somatic index).
Histological indices are respectively the area and circumference of seminiferous tubules, each testis and their crosswise dissections, the diameter of seminiferous tubules and the number of seminiferous tubules per square millimeter, that were determined.
Results: The values of the two test groups were determined and compared with the results of normal group that were using normal saline only and the blank that were receiving propyllenglycol only.
Conclusion: The significant inhibitive activity of candidate compounds on animal's physiologic indices were in accordance of our pervious estimation of compounds activity as (lead compound) for synthesis and preparation of new compounds with male contraceptive activity

Abstract
Background: Postpartum depression is a mood disorder that has harmful effects on mothers,
infants, family and relationships. Acute decrease of progesterone after delivery has been proposed as a cause for postpartum depression. This
hormone can affect neurotransmitters' function. Zinc (Zn) and magnesium (Mg) as trace elements exert their antidepressant effects through
neurotransmitter pathways. On the other hand, thiamin (Vit B1) deficiency leads to depression in animal models. The aim of this study
was to evaluate effects of combination of zinc, magnesium and thiamine on postpartum depression and role of nitrergic system.
Methods: One hundred ten female mice in five groups were used. Postpartum depression was conducted using progesterone injections. Combinations of
Zinc chloride, magnesium chloride and thiamine HCL were administered 30 minutes before open field and forced swimming test (FST). In order to
investigate role of nitrergic system, L-arginine and LNAME were administered.
Results: All treatment groups spent less immobility time than the control group (p< 0.05). Combined administration of Zn+ Mg+ Vit B1 caused the most reduction in immobility time. Administration of L-NAME in Zn+ Mg+ Vit B1 group caused reduction in immobility time while administration of L-arginine caused increase in immobility time in the same group.
Conclusion: Zinc, magnesium and thiamine can improve depressive symptoms by nitrergic pathway. These elements as supplement compounds could be alternatives for antidepressants in postpartum period.

Abstract
Background: Creatine kinase is a cardiac biomarker that is used for the assessment of ischemic injuries and myocardial infarction. The present study was designed to evaluate effects of oxytocin administration during ischemia and reperfusion periods on CK-MB levels in the coronary effluent of isolated rat heart and the possible role of oxytocin receptor, nitric oxide (NO), prostacyclin and mitochondrial ATP-dependent potassium channels in this regard.
Methods: Male wistar rats (n=8) were anesthetized with sodium thiopental and their hearts were transferred to a Langendorff perfusion apparatus. All animals were randomly divided into nine groups as follow in the ischemia-reperfusion group, hearts underwent 30 min of regional ischemia followed by 120 min of reperfusion. In oxytocin group, hearts were perfused with oxytocin 5 min after ischemia induction for 25 min. In other groups, 35 min prior to oxytocin perfusion, atosiban (a non-specific oxytocin receptor blocker), L-NAME (an NO synthase inhibitor), indomethacin (a non-specific cyclooxygenase blocker) and 5-HD (a specific mKATP channel blocker) were perfused for 10 min. In all groups, we measured CK-MB levels in the coronary effluent at the end of reperfusion. Moreover, coronary flow (mL/min) was measured at baseline, during ischemia period and 60 and 120 min after reperfusion.
Results: Oxytocin administration significantly reduced CK-MB level in oxytocin group as compared to ischemia-reperfusion group. Administration of atosiban, L-NAME, indomethacin and 5-HD prior to oxytocin perfusion abolished the effects of oxytocin on CK-MB levels.
Conclusion: Administration of oxytocin during ischemia and reperfusion periods deceased CK-MB levels but infusion of atosiban, L-NAME, 5-HD and indomethacin inhibited oxytocin from exerting its effects.

Abstract
Background: Breast cancer is one of the most important causes of death in women. One of the various gene expression involved in breast cancer is human epidermal growth factor receptor 2 (HER2/neu) gene expression increases. Factors of dietary affect on regulation of hormone secretion and the rate of breast cancer. One of these factors is amount and type of fats in diet. Gamma-linolenic acid (GLA) and Docosah-exaenoic acid (DHA) are members of poly unsaturated fatty acids. In this study, effects of dietary GLA and DHA alone or together with paclitaxel on treatment of mice mammary carcinoma has been evaluated.
Methods: Thirty female balb/c mice were divided in six groups randomly. Carcinoma-tous mass induced by tumor implantation method. Spontaneous breast adenocarcinoma of mice were used as tumor stock. The tumors of these mice were removed aseptically, dissected into 0.5 cm3 pieces. These pieces were transplanted subcutaneously into their right flank. GLA and DHA added to the mice diet two week prior to tumor implanta-tion. At the end of intervention, tumors were removed and HER2 gene expression was measured. The weight of animal and tumor volume measured weekly.
Results: It was not significant change in the weight of animals that consumed DHA and DHA with taxol. Tumor volume in those groups that received corn oil with taxol (P<0.01), DHA (P<0.05) and DHA with taxol (P<0.001) showed significant decrease in comparison with control group. HER2 gene expression in DHA with taxol decreased significantly in comparison with control group (P<0.05).
Conclusion: Consumption of DHA oil with taxol causes decrease the volume of carcin-oma mass. The future studies with large number of sample is needed to support this finding.

Abstract
Background: Postpartum depression (PPD) is a major depressive disorder and one of the most common complications of childbearing. PPD has a serious impact on the quality of life of all family members. Oxidative stress is one of the contributing factors in pathophysiology of major depression. Thus, drugs with potential antioxidant action could be an attractive target for treatment of depressive disorders. Matricaria Chamomilla and Selenium are natural sources of antioxidant. The aim of this study was to evaluate effects of oral administration of Matricaria Chamomilla aqueous extract and Selenium on experimental model of progesterone-induced postpartum depression and plasma oxidant-antioxidant system in mice.
Methods: Seventy adult female mice in seven groups were used in this study. All animals received daily injections of progesterone 5 mg/kg intraperitoneally for five days after which progesterone was withdrawn for three days. After modelling postpartum depression with progesterone withdrawal, Matricaria Chamomilla 300 mg/kg and Selenium 0.1 mg/kg and their combination were administered via gavage and imipramine 15 mg/kg was administered intraperitoneally one hour before open field and forced swimming test (FST). In order to investigate the role of oxidant-antioxidant system, PAB and MDA were meatured.
Results: All the treatment groups and the standard group spent less immobility time than the control group (P<0.05). Significant changes in the oxidative parameter (PAB and MDA) were not observed in all treatment groups and the standard group compared to the control group.
Conclusion: Our study demonstrated the potential antidepressant activity of Matricaria chamomilla and Selenium in the experimental model of progesterone-induced postpartum depression in mice. These elements as supplement compounds could be alternatives for antidepressants in postpartum period. It seems that the antidepresent effects of this compounds do not induced by effects on oxidant-antioxidant system and may exert through any other pathway.
