background: radiation-induced lung injury is a refractory side effect in lung cancer radiotherapy, the mechanism still remains unclear, hence an appropriate animal mode may become useful to investigate it. materials and methods: 50 female wistar rats were randomly divided into 5 groups, average 10 rats/cage: a. control group b. 3gy×10f c. 6gy×5f d. 12.5gy×1f e.15.3gy×1f. by different doses of r...
background: sulfur mustard is one of the chemical warfare gases that has been known as a vesicant or blistering agents. it is a chemical alkylating compound agent that can be frequently absorbed through skin, respiratory system, genital tract, and ocular system. this study was done to pathologically analyze the microscopic pancreatic lesions in cadavers. methods: this case series study was perf...
objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali). materials a...
background: vitamin d, especially its most active metabolite 1,25-dihydroxyvitamin d₃(vit d) is essential in regulating a wide variety of biologic processes, such as regulating mesangial cell activation. the objective of this study was to assess the histopathological changes of effectiveness of vit d as a protective agent against radiation induced lung injury. materials and methods: eighteen wi...

background: acute kidney injury (aki) has been recognized as one of the most complex clinical complications in modern medicine, and ischemia/reperfusion (i/r) injury is well-known as a main reason of aki. in addition, aki leads to important systemic consequences such as acute lung injury. this study was designed to investigate the role of erythropoietin (epo) on kidney function makers and tissu...
background: about 100,000 iranian have been exposed to chemical weapons during iraq‑iran conflict (1980‑88). after being spent of more than two decades, still about 30,000 of them are under follow‑up treatment. the main aim of this study was to review various preventive and therapeutic methods for injured patients with sulfur mustard in different phases. methods: for gathering information, we h...
objective(s): abnormal lung cell death including autophagy and apoptosis is the central feature in acute lung injury (ali). to identify the cellular mechanisms and the chronology by which different types of lung cell death are activated during lipopolysaccharide (lps)-induced ali, we decided to evaluate autophagy (by lc3-ii and autophagosome) and apoptosis (by caspase-3) at different time point...
background: many of the multiple traumatized patients who refer to the hospital need transfusion. transfusion-related acute lung injury (trali) is a serious clinical syndrome associated with the transfusion of plasma-containing blood components. in the article, we present a case of trali following transfusion of packed red blood cells case presentation: a 24 year old male referred to shahid beh...
conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...
