چکیده
AN!) EUGENE P. CRoNKIT1 T HE anemia produced by whole body exposure to lethal doses of ionizing radiations develops more rapidly than would be expected from cessation of erythropoiesis t.ogether w’ith the normal attrition of cells. In large measure the excess loss of red cells is accounted for by hemorrhage, incident to the t.hrombocytopenia which occurs as the result of bone marrow aplasia. It also has been frequently suggested that hemolysis contributes to the rapid onset of anemia.1 27

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...
متن کاملسطح آنتیاکسیدان تام پلاسما و عملکرد سیستم ایمنی پرسنل رادیولوژی و پزشکی هستهای بیمارستانهای دانشگاه علوم پزشکی تهران
Background: Despite major diagnostic and industrial progresses in the technology and use of Ionizing radiations, they have been found to be harmful to the health of the radiology and nuclear medicine staffs. Since Ionizing radiations have the potential to produce free radicals, therefore, it is likely that the total plasma level of anti-oxidant in medical and nuclear medicine staffs could be re...
متن کاملبررسی میزان مواجهه شغلی با پرتوهای غیریونساز و اثربخشی وسایل حفاظت فردی در انواع جوشکاری قوس الکتریکی متداول
Introduction: Welding is considered to be one of the main sources of occupational exposure to non ionizing radiations. The present study was conducted to examine the rate of occupational exposure to non-ionizing radiation in common welding processes. Materials and Methods: In the present descriptive analytical study, occupational exposure to different types of non-ionizing radiations in...
متن کاملAssessment of polymer composite reinforced with nanomaterial against ionizing radiation
Introduction: Unwanted exposure of ionizing radiation may result in carcinogenesis, cell mutations, and organ failure. High-atomic number elements such as lead, tungsten, bismuth have been traditionally used for radiation protection. Theoretical and practical studies have shown that a variety of shielding materials e.g. polymer composites (PCs) can be used for attenuation of th...
متن کاملTrack detection on the cells exposed to high LET heavy-ions by CR-39 plastic and terminal deoxynucleotidyl transferase (TdT)
Background: The fatal effect of ionizing radiation on cells depends on Linear Energy Transfer (LET) level. The distribution of ionizing radiation is sparse and homogeneous for low LET radiations such as X or γ, but it is dense and concentrated for high LET radiation such as heavy-ions radiation. Material and Methods: Chinese hamster ovary cells (CHO-K1) were exposed to 4 Gy Fe-ion 2000 keV/...
