[ 1 ] - بررسی تغییرات سوپراکسید دیسموتاز (SOD)، گلوتاتیون (GSH) و مالون دی آلدهید (MDA) و هیستولوژیک ناشی از تشعشع گاما بر بافت ریه موش صحرایی
زمینه و هدف: ریه یک ارگان حساس و آسیب به آن عامل محدودکننده دوز در پرتودرمانی است. عوارض جانبی مختلف شامل پنومونی و فیبروز ریه مربوط به بیماران مبتلا به تابش قفسه سینه است. مطالعه حاضر باهدف بررسی اثر پرتوگاما در آسیب‌های حاد و مزمن در بافت ریه موش صحرایی نر انجام شده است. مواد و روش‌ها: 32 موش به دو گروه تقسیم شدند. گروه کنترل، 14 موش تحت شم تابش قرار گرفتند. گروه پرتو، 18 موش تحت تابش قرار گر...
[ 2 ] - Investigating Indoor Radon Concentration Using CR-39 Detector; a Case Study of Gachin Dwellings in Hormozgan
Introduction: Radon is a colorless inert gas which decay products are the main component of natural radioactive elements that are naturally produced in under layers of earth crust by decay of radium and uranium. It enters through buildings via gaps and cracks. Radon gas decay products like alpha particle can increase the incidence of lung cancer in human. Since every person sp...
[ 3 ] - Knowledge, Attitude, and Performance of Radiographers about the Principles of Radiation Protection and Following Protective Standards in Medical Imaging Centers of Hospitals in Fasa in 2015
Background & Objectives: Although ionizing radiation is effective in the diagnosis of illnesses, it is dangerous from the perspective of protection for patients and radiographers working in radiology sections. Therefore, knowledge, understanding, and application of radiation protection can play an important role. The aim of this study is to assess the knowledge, attitude, and practice of the ra...
[ 4 ] - Evaluation of Absorbed Dose of Critical Organ in Rando Phantom under Head, Abdomen and Pelvis Spiral CT Scan by Thermo Luminescent Dosimetery - TLD
Background & Objectives: Computed tomography (CT) represents 11% of all diagnostic radiology procedures but it contributes to almost 67% of the total effective dose to the human population. In head and neck CT which consist of 1/3 of total CT scans, other critical organs such as lenses and thyroid are in the radiation field. Also in the abdomen and pelvis scan, irradiation of ovaries is unavoid...
[ 5 ] - The Evaluation of Melatonin Effect Against The Early Effect of Ionizing Radiation Induced Lung Injury
Background & Objective: Lung is a radiosensitive organ. Patients who are undergoing radiation therapy in their chest are subjected to radiation pneumonitis in the early phase and pulmonary fibrosis in the late one. Melatonin scavenges free radicals directly and acts as an indirect antioxidant through the activation of major antioxidant enzymes as well. The aim of the study thus is to investiga...
[ 6 ] - Assessment of Radon level in dwellings of Tabriz
Background & Objective: Indoor radon gas (222Rn) has been recognized as one of the causes of lung cancer. The presence of radioactive radium in the construction & materials in the buildings its changes in contact with radon gas may lead to increase level of radon gas in the residential houses. In this regards, indoor radon measurement is important. This study was conducted to determine radon co...
[ 7 ] - The Mechanisms of Radiation-Induced Bystander Effect
The radiation-induced bystander effect is the phenomenon which non-irradiated cells exhibit effects along with their different levels as a result of signals received from nearby irradiated cells. Responses of non-irradiated cells may include changes in process of translation, gene expression, cell proliferation, apoptosis and cells death. These changes are confirmed by results of some In-Vivo s...
