lung protection strategy as an effective treatment in acute respiratory distress syndrome

To provide proper medical care for patients after a radiation incident, it is necessary to make the correct diagnosis in a timely manner and to ascertain the relative magnitude of the incident. The present article addresses the clinical diagnosis and management of high-dose radiation injuries and illnesses in the first 24 to 72 hours after a radiologic or nuclear incident. To evaluate the magni...

The radioprotective effect of indralin in rhesus monkeys was examined over 60 d following gamma irradiation. Male and female rhesus macaques (Macaca mulatta) 2-3-years-old and weighing 2.1-3.5 kg were used. Animals were exposed to total-body gamma irradiation from (60)Co at a dose of 6.8 Gy (lethal dose, 100% lethality over 30 days). Indralin (40-120 mg kg(-1)) was administered intramuscularly ...

Radiation accidents frequently involve acute high dose partial body irradiation leading to victims with radiation sickness and cutaneous radiation syndrome that implements radiation-induced cell death. Cells that are not lethally hit seek to repair ionizing radiation (IR) induced damage, albeit at the expense of an increased risk of mutation and tumor formation due to misrepair of IR-induced DN...

The goal of combined pharmacological approaches in the treatment of the acute radiation syndrome (ARS) is to obtain an effective therapy producing a minimum of undesirable side effects. This review summarizes important data from studies evaluating the efficacy of combining radioprotective agents developed for administration prior to irradiation and therapeutic agents administered in a post-irra...

Post-radiation syndrome is proposed to be chronic fatigue syndrome (CFS) or a chronic fatigue syndrome-like illness, initiated by exposure to ionizing radiation. This view is supported by the nitric oxide/peroxynitrite (NO/ONOO-) cycle mechanism, the putative etiologic mechanism for CFS and related illnesses. Ionizing radiation may initiate illness by increasing nitric oxide levels via increase...

The hematopoietic syndrome is anticipated when a dose of radiation greater than 100 cGy is received. The resulting clinical situation is life-threatening because of opportunistic infections and gradual decline in immune competency due to irradiation. Because of evidence of a possible immunomodulatory role for cimetidine, an antagonist of histamine H2 receptors, we studied the effects of thi...

Known commonly as "broken heart syndrome," takotsubo cardiomyopathy is a poorly understood heart condition that results in acute decompensation of cardiac function. We report a case of a 68-year-old female who developed acute shortness of breath status after chemotherapy and radiation treatment for Stage IV squamous-cell carcinoma. Computed tomography pulmonary angiogram (CTPA) revealed a singl...

background: acute coronary syndrome is a life-threatening condition. considerable doubts exist over the effects of this disease on patients’ quality of life. the aim of this study was to survey quality of life and its influencing factors in patients with acute coronary syndrome. methods: a convenience sample of 300 patients with acute coronary syndrome was drawn from shahid beheshti hospital, k...
