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...
The present study aimed to investigate the therapeutic effect of monoammonium glycyrrhizinate (MAG) on lipopolysaccharide- (LPS-) induced acute lung injury (ALI) in mice and possible mechanism. Acute lung injury was induced in BALB/c mice by intratracheal instillation of LPS, and MAG was injected intraperitoneally 1 h prior to LPS administration. After ALI, the histopathology of lungs, lung wet...
acute respiratory distress syndrome (ards) is a complex disorder of heterogeneous etiologies characterized by a consistent, recognizable pattern of lung injury and a potentially devastating form of acute inflammatory lung injury with a high short-term mortality rate and significant long-term consequences among survivors. recently, the new definition of ards has been published, and this definiti...
Background: Sepsis is most likely to cause lung damage in patients, and the detection rate mortality are high. Here, we investigated expression of miR-20a sepsis-induced acute injury (ALI) rats its effect on inflammatory response, reveal possible molecular mechanism. Method: The model caused by sepsis was established cecal ligation puncture. tissue determined RT-qPCR. Acute were injected with 5...
The mortality of acute lung injury and acute respiratory distress syndrome (ALI/ARDS) remains high and efforts for prevention and treatments have shown little improvement over the past decades. The present study investigated the efficacy and mechanism of leukocytapheresis (LCAP) to partially eliminate peripheral neutrophils and attenuate lipopolysaccharide (LPS)-induced lung injury in dogs. A t...
BACKGROUND Metallothionein (MT) is a protein that can be induced by inflammatory mediators and participate in cytoprotection. However, its role in inflammation remains to be established. A study was undertaken to determine whether intrinsic MT protects against acute inflammatory lung injury induced by bacterial endotoxin in MT-I/II knock out (-/-) and wild type (WT) mice. METHODS MT (-/-) and...
Acute inflammatory injury in rat lung induced by deposition of immunoglobulin G immune complexes requires expression of cytokines and chemokines as well as activation of the transcription factor nuclear factor (NF)-kappaB. There is little direct evidence regarding the role of alveolar macrophages in these activation events. In the present studies, rat lungs were depleted of alveolar macrophages...
The dried roots of the plant Acanthopanax senticosus (AS) are used in traditional Oriental medicine and reportedly possess anti-inflammatory properties in vitro. However, whether AS has the same anti-inflammatory effect in vivo and the underlying mechanisms of this action remain unknown. In this study, we pretreated a mouse model of lipopolysaccharide-induced acute lung injury with AS and found...
Fasudil, a selective rho kinase (ROCK) inhibitor, has been reported to play a beneficial role in systemic?inflammation?in acute?lung injury, but its mechanism for ameliorating pulmonary edema and inflammation remains unclear. Using hematoxylin-and-eosin (HE) staining, immunohistochemistry, enzyme-linked immunosorbent assay, quantitative real time PCR and Western blotting, we found that fasudil ...
The aim of the present study was to explore the protective effect of small interfering RNA (siRNA) against nuclear factor κB (NF-κB) p65 on sepsis-induced acute lung injury (ALI) in mice. In total, 70 male Kunming mice were randomly divided into a healthy control group, a sepsis group, a specific interfering group and a scrambled control group (Sc), and the latter three groups were divided into...
