[ 1 ] - Isolation of bovine spermatogonial cells and co-culture with prepubertal sertoli cells in the presence of colony stimulating factor-1
BACKGROUND: Spermatogonial stem cells (SSCs) are infrequentself-renewing cells among the type A spermatogoniawithin the seminiferous tubules and are the basis of spermatogenesisin mammalian testis. An adequate number of SSCs is aprimary requirement for the study of their behavior, regulation, andfurther biomanipulation. OBJECTIVES: In this paper, we studiedthe development of the primary co-cult...
[ 2 ] - بررسی تأثیر سلنیوم بر تغییرات ظرفیت آنتی اکسیدانی اسپرم موشهای مسن و بالغ
زمینه و هدف: سلنیوم یک ماده آنتی اکسیدانی است که برای عملکرد طبیعی بیضه و انجام پروسه اسپرماتوژنزیس ضروری می‌باشد. این ماده قادر به کاهش رادیکالهای آزاد اکسیژن می‌باشد و لذا انتظار می‌رود که در افزایش باروری مؤثر باشد. هدف از این مطالعه بررسی تغییرات ظرفیت آنتی اکسیدانی کل اسپرم موشهای مسن پس از تجویز mg/kg2/0 سلنیوم بوده است. روش بررسی: این پژوهش به شیوه تجربی و با آزمایش بر روی 15 سرموش بال...
[ 3 ] - تأثیرات شوک سرمایی بر کورتکس حسی- حرکتی مغز موش بالغ
زمینه و هدف: شوک سرمایی به عنوان یک مدل مفید برای مطالعه مکانیزم آسیب مغزی تروماتیک بکار می‌رود. از این مدل برای ایجاد ادم مغزی استفاده می‌گردد. ادم مغزی یک وضعیت پاتوفیزیولوژیک است که در آن میزان آب مغز افزایش می‌یابد. این حالت می‌تواند بدنبال انواعی از آسیب‌های مغزی از جمله ایسکمی، تروما، تومور و عفونت رخ دهد. هدف این مطالعه ارزیابی تأثیرات شوک سرمایی بر کورتکس حسی-حرکتی مغز موش بود. روش بر...
[ 4 ] - بررسی اثر فاکتور رشد اپیدرمال بر تکوین جنین‌های 16-8 سلولی موش و بیان ژن گیرنده این فاکتور پس از انجماد شیشه‌ای
چکیده زمینه و هدف: انجماد جنین‌های انسانی یک فعالیت روتین در درمانگاههای درمان ناباروری می‌باشد. تکوین موفقیت‌آمیز و لانه‌گزینی جنین‌های منجمد شده به میزان زیادی به محیط کشت مناسب، فاکتورهای رشد، سایتوکاینها و بیان ژنومی دارد. مطالعات اخیر بیانگر نقش مهم فاکتور رشد اپیدرمال (EGF) و رسپتور آن در تکوین جنین و مراحل لانه‌گزینی می‌باشند. هدف از این مطالعه تعیین تأثیر فاکتور رشد اپیدرمال در تکوین...
[ 5 ] - بررسی اثر آنتی اکسیدان ها بر کیفیت اسپرم منجمد - ذوب شده با روش انجماد سریع
Background and Purpose: Antioxidant reduces oxidative stress during cryo-preservation. The aim of this study was to find out the effects of vitamin E and C on sperm parameters after cryo-preservation. Materials and Methods: Human semen samples were obtained from Vali-e-asr Hospital. The samples were divided in two groups (normal and oligospermia groups). Semen was pooled in liquid nitrogen...
[ 6 ] - Evaluation of Apoptotic Genes Expression and Its Protein after Treatment of Cryptorchid Mice
Introduction: Cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. The purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. Methods: To induce bilateral cryptorchid model, immature mice were anesthetized and a...
[ 7 ] - The Morphological Changes of Adult Mouse Testes after 60Co γ-Radiation
Background: Cytotoxic therapy can lead to prolonged azoospermia or even sterility. In the present study, we investigated the morphological changes of mouse testes after gamma-Radiation. Methods: After anaesthetizing of NMRI mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. Four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+1...
[ 8 ] - Comparison of Embryo Development between Intracytoplasmic and Piezo-Assisted Sperm Injection after Treating Mouse Sperms by Ca2+ Ionophore
The purpose of this study was to evaluate the efficiency of intracytoplasmic sperm injection (ICSI) and Piezo-assisted sperm injection after pretreatment with calcium ionophore (CaI) on the mouse embryo development. Methods: In this study, the conventional ICSI and Piezo-ICSI procedures were used. The efficacy of the methods was examined after mouse matured oocytes were fertilized with or witho...
[ 9 ] - Assessment of Morphological and Functional Changes in the Mouse Testis and Epididymal Sperms Following Busulfan Treatment
Busulfan, a cytotoxic drug, which is currently used as a chemotherapeutic agent, has many side effects on different body organs. In this research, the effects of busulfan on sperm parameters and microstructure of mouse testis were investigated. Methods: Busulfan was injected intrapretoneally at 10, 20, 30, 40 and 50 mg/kg and testes were removed after 4, 6 and 8 weeks, weighed and processed fo...
[ 10 ] - Chronic effects of moderate intensity endurance training on neuropathic pain symptoms in diabetic rats
Introduction: Neuropathic pain is a chronic pain that occurs as an injury to neuronal cells and abnormality in nervous and immune systems function. Also diabetic neuropathy diseases accompany with variety of pain syndromes such as allodynia and hyperalgesia. Thus, the aim of the present study was to investigate the chronic effects of incremental activity in the form of endurance training o...
[ 11 ] - بررسی تغییرات بافت بیضه و شاخصهای اسپرم در موش قطع نخاعی شده به روش Contusion در دوره حاد پس از آسیب
Background and Aim: Infertility is one of the major problems associated with contusive spinal cord injury (SCI). Sperm qualities such as low viability, low motility, and increase in abnormal morphology are complications arising from infertility following SCI. The purpose of this study was to evaluate testicular changes and spermatic parameters after contusive spinal cord injury in the mice. ...
