[ 1 ] - تأثیر پماد هایپریکوم پرفوراتوم (پرفوران) بر بهبودی زخم و درد اپی‌زیاتومی
مقدمه: اپی‌زیاتومی شایع‌ترین برش جراحی پرینه در حین زایمان واژینال است ومانندهر برشدیگرخطراتیدارد. یکی از عواملی که اخیراً در بهبود زخم اپی‌زیاتومی مورد توجه زیادی قرار گرفته است، کاربرد گیاهان دارویی است. عصاره هایپریکوم پرفوراتوم باعث مهار آراشیدونیک اسید A و آنزیم سیکلواکسیژناز و کاهش التهابودرد می‌شود. همچنین عصاره این گیاه به عنوان یک داروی ضدعفونی کننده برای زخم‌های جراحی به کار رفته است. ...
[ 2 ] - Problems of Cold Agglutinins in Cardiac Surgery: How to Manage Cardiopulmonary Bypass and Myocardial Protection
Cold agglutinins are of unique relevance in cardiac surgerybecause of the use of hypothermic cardiopulmonary bypass (CPB). Cold autoimmune diseases are defined by the presence of abnormal circulating proteins (usually IgM or IgA antibodies) that agglutinate in response to a decrease in body temperature. These disorders include cryoglobulinemia and cold hemagglutinin disease.Immunoglobulin M aut...
[ 3 ] - Emergency Conversion from Off Pump to Cardiopulmonary Bypass in Patients with Coronary Artery Bypass Graft Surgery
Introduction: As off pump Coronary artery bypass grafting surgery (CABG) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. In this observational study we tried to show the rate and outcome of conversion . Material and methods: In this descriptive study about 477 coronary off-pump CABG patients were operated in Ghaem hos...
[ 4 ] - Role of nitric oxide on the electrophysiological properties of isolated rabbit atrioventricular node by extracellular field potential during atrial fibrillation
Introduction: The aim of the present study was to determine direct effects of NO modulation on protective electrophysiological properties of atrioventricular node (AV node) in the experimental model of AF in rabbit. Methods: Isolated perfused rabbit AV nodal preparations were used in two groups. In the first group (N=7), LNAME (50μM) was applied. In the second group (N=12), different concent...
[ 5 ] - Dynamic age-related changes of extracellular field potential of isolated AV-node of rabbit
Introduction: Developmental changes in atrioventricular nodal conduction time and refractoriness have been shown in several studies. Prevalence of atrioventricular nodal reentrant tachycardia (AVNRT) is clearly age-dependent. The purpose of this study was to determine developmental changes of basic and frequency-dependent electrophysiological properties of the atrioventricular node (AV-node)...
[ 6 ] - Protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using extracellular field potential recordings of isolated atrioventricular-node of rabbit
Introduction: Recent studies have shown acute cardioprotective effects of cyclosporine. The aim of the present study was to determine the protective role of cyclosporine on the model simulated the rotational nodal arrhythmia (AVNRT) by using extracellular field potential recordings of isolated atrioventricular-node (AV-node) of rabbit. Methods: This study was performed on isolated double-per...
[ 7 ] - Frequency-dependent anti arrhythmic effects if Crataegus monogyna on extracellular field potential recording in experimental model of AF atrioventricular Node of rabbit.
Introduction: Despite extensive studies about effects of Crataegus monogyna on cardiovascular diseases yet, a few study has been undertaken antiarrhythmic property of this plant. Aims of the present study were: 1) To determine the protective role of methanolic extract of C.monogyna on the rate-dependent model and the concealed conduction . 2) To explore the role of Na+-K+ A TPase in the protect...
[ 8 ] - Age-dependent dynamic electrophysiological field potential behavior of atrioventricular node during experimental AF in rabbit
Introduction: Electrophysiological studies have demonstrated a relationship between aging and atrioventricular (AV) nodal conduction and refractoriness. The aim of the present study was to determine the effects of nodal aging on dynamic AV nodal field potential recording during atrial fibrillation (AF) in rabbit. Methods: Two groups of male New Zealand rabbits (neonatal 2-week-olds and adult...
[ 9 ] - برآورد شاخص‌های آسیب‌پذیری و تاب‌آوری در اقتصاد ایران
هدف اساسی این مقاله، ارائه روشی برای تحلیل و اندازه‌گیری شاخص آسیب‌پذیری و تاب‌آوری در اقتصاد ایران است. تاب‌آوری اقتصادی، توانایی پرورش‌یافته اقتصاد برای بهبود یا تعدیل اثر شوک‌های منفی در برابر چیزی است که ممکن است در اقتصاد نمایان شود. مقاله حاضر، چهار جنبه ثبات اقتصاد کلان شامل کارایی بازار اقتصاد خرد، حکومت و توسعه اجتماعی و شاخص تاب‌آوری و آسیب‌پذیری اقتصادی ایران را در دوره 1395-1375 برر...
[ 10 ] - Ultrasonic Assisted Extraction of Natural Pigments from Rhizomes of Curcuma Longa L.
Ultrasound-assisted extraction (UAE) was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of curcuminoids from turmeric plant rhizomes. The turmeric samples were extracted under indirect sonication in an ultrasonic bath, and compared with the conventional methods. It was found that the yield of ultrasound-assisted extraction was approxim...
[ 11 ] - تاثیر ۸ هفته تمرین استقامتی بر بیان ژن امنتین-1 بافت چربی احشایی رت های نر دیابتی شده با استرپتوزوتوسین
زمینه و هدف: دیابت یکی از معضلات سلامتی در تمامی جوامع محسوب می شود و مداخله ورزشی از جمله رویکردهای بهبود وضعیت افراد دیابتی تلقی می‌گردد. هدف از تحقیق حاضر بررسی تأثیر تمرین استقامتی بر بیان ژن امنتین-۱ بافت چربی احشایی در موش‌های نر دیابتی نژاد ویستار بود. روش تحقیق: از بین 19 سر رت نر نژاد ویستار، به صورت تصادفی ۶ سر رت به عنوان گروه کنترل پایه انتخاب شدند. دیابت بر رت های باقی مانده از ط...
