Acute lung injury carries a high burden of morbidity and mortality and is characterised by nonhydrostatic pulmonary oedema. The aim of this paper is to highlight the role of accurate quantification of extravascular lung water in diagnosis, management, and prognosis in "acute lung injury" and "acute respiratory distress syndrome". Several studies have verified the accuracy of both the single and...
New evidence indicates that neural mechanisms can down-regulate acute inflammation. In these studies, we tested the potential role of the 7 nicotinic acetylcholine receptor ( 7 nAChR) in a rodent model of acid-induced acute lung injury. We first determined that the 7 nAChR was expressed by alveolar macrophages and lung epithelial cells. Then, using an acid-induced acute lung injury mouse model,...
It is known that respiratory syncytial virus (RSV) is the main cause of bronchiolitis and pneumonia in young children. RSV infection often leads to severe acute lung immunopathology, but the underlying immune mechanisms are not yet fully elucidated. Here, we found that RSV infection induced severe acute lung immune injury and promoted the accumulation and activation of lung natural killer (NK) ...
background acute lung injury (ali) is defined as pao2/fio2 less than 300 with bilateral pulmonary infiltrates, without pressure is the top of the left atrium. early diagnosis and treatment of pediatric ali and find new cases is very important. accurate diagnosis and effective steps to treating these patients is essential in the outcome of ali. this study was conducted to show the impact of recr...
Acute lung injury is caused by many factors including acute pancreatitis. There is no specific therapy directed at underlying pathophysiological mechanisms for acute lung injury. Transforming growth factor-β (TGF-β) is involved in the resolution of lung injury in later phases of the disease. Some evidence exists demonstrating that TGF-β not only is involved in the late stages, but also contribu...
In addition to its well-known association with lung infection (i.e., pneumonia), alcohol abuse now is recognized as an independent factor that increases by three- to four-fold the incidence of the acute respiratory distress syndrome, a severe form of acute lung injury with a mortality rate of 40 to 50 percent. This translates to tens of thousands of excess deaths in the United States each year ...
New evidence indicates that neural mechanisms can down-regulate acute inflammation. In these studies, we tested the potential role of the alpha7 nicotinic acetylcholine receptor (alpha7 nAChR) in a rodent model of acid-induced acute lung injury. We first determined that the alpha7 nAChR was expressed by alveolar macrophages and lung epithelial cells. Then, using an acid-induced acute lung injur...
A moderate pulmonary hypertension is a hallmark of experimental, as well as clinical, acute lung injury. Pulmonary hypertension in acute lung injury, appears to be caused primarily by a partially reversible increase in extra-alveolar vascular closing pressure, the latter being modulated by vasodilating products of the cyclooxygenase pathway of arachidonic acid metabolism, as well as by an endog...
