BACKGROUND Damaged metal halide lamps are known to cause outbreaks of photokeratitis and UV-radiation burns among children and adults, which has prompted the Food and Drug Administration, Rockville, Md, to publish consumer recommendations to prevent such injuries. We investigated 3 outbreaks of photokeratitis and UV-radiation burns in gymnasiums associated with failure to heed these recommendat...
background and aims. salivary glands are extremely susceptible to radiation injuries. the aim of this study was to evaluate radiation-induced xerostomia in patients with nasopharyngeal carcinomas, referring to tabriz imam khomeini hospital in 2005-2006. materials and methods. thirty patients with nasopharyngeal carcinomas, who received conventional radiotherapy, were included in the present stu...
Pharmacological mitigation of injuries caused by high-dose ionizing radiation is an unsolved medical problem. A specific nonlipid agonist of the type 2 G protein coupled receptor for lysophosphatidic acid (LPA2) 2-[4-(1,3-dioxo-1H,3H-benzoisoquinolin-2-yl)butylsulfamoyl]benzoic acid (DBIBB) when administered with a postirradiation delay of up to 72 hr reduced mortality of C57BL/6 mice but not L...
Exposure of skin to solar ultraviolet (UV) radiation induces photo-damage. Ultraviolet B (UVB) is the major component of UV radiation which induces the production of reactive oxygen species (ROS) and plays an important role in photo-damage. Hydrogen gas reduces ROS and alleviates inflammation. In this study, we sought to demonstrate that hydrogen-rich saline has the effect on skin injuries caus...
Skin injuries such as wounds or burns following whole-body γ-irradiation (radiation combined injury (RCI)) increase mortality more than whole-body γ-irradiation alone. Wound-induced decreases in survival after irradiation are triggered by sustained activation of inducible nitric oxide synthase pathways, persistent alteration of cytokine homeostasis, and increased susceptibility to systemic bact...
Effective therapy for chronic radiation injuries, such as ulcers, is prone to infection. Stiffness is expected since the therapeutic radiation often involves wider and deeper tissues and often requires extensive debridement and reconstruction, which are not sometimes appropriate for elderly and compromised hosts. Autologous adipose-derived regenerative cells (ADRCs) are highly yielding, forming...
SEE PAGE 616 A lthough advances have been made in the diagnosis of and therapy for cardiovascular disease, this has not come without risks. This risk includes a 3-fold increase in patient medical radiation exposure over the past 25 years (1), with all imaging areas challenged to reduce patient dose (2). Although interventional cardiology contributes a small component to this increase, when a cu...
The distinctive feature of the atomic bomb is the large amount of radiant energy that it produces. While this energy covers a wide range of the electromagnetic spectrum, its chief physiologic and pathologic effects may be divided into two groups: first, the effects of heat, producing primary thermal injury of the flash burn type, and secondary thermal injuries due to induced fires; second, the ...
Radiation therapy is an important therapeutic modality for thoracic malignancies. However, radiation-induced pulmonary injuries such as radiation pneumonitis and fibrosis are major dose-limiting factors. Previous research shows that micro-computed tomography (micro-CT) can detect radiation-induced lung injuries a few months following irradiation, but studies to assess the early response of lung...
