objective(s): to study the effect of cardiopulmonary bypass (cpb) on nuclear factor-kappa b (nf-кb) and cytokine expression and pulmonary function in dogs. materials and methods: twelve male mongrel dogs were divided into a methylprednisolone group (group m) and a control group (group c). all animals underwent aortic and right atrial catheterization under general anesthesia. changes in pulmonar...
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 ...

Objective(s): To investigate the protective effect of S-nitrosoglutathione (SNG) pretreatment on acute lung injury (ALI) in septic rats. Materials and Methods: We constructed a rat model of sepsis by cecal ligation and perforation (CLP), and randomly divided into Sham, CLP, and CLP+SNG (0.25 and 0.5 mg/kg) groups. We used H&E; staining an...
INTRODUCTION Nuclear factor (NF)-κB is central to the pathogenesis of inflammation in acute lung injury, but also to inflammation resolution and repair. We wished to determine whether overexpression of the NF-κB inhibitor IκBα could modulate the severity of acute and prolonged pneumonia-induced lung injury in a series of prospective randomized animal studies. METHODS Adult male Sprague-Dawley...
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...
Experimental evidence suggested that sodium ferulate (SF) and oxymatrine (OMT) combination had synergistic anti-inflammatory and antioxidant effects. We hypothesized that SF and OMT combination treatment might have protective effects on paraquat-induced acute lung injury. In our study, the Swiss mice were randomly divided into seven groups, including control, paraquat (PQ), SF (6.2 mg/kg/day); ...
Acute lung injury occurs as a result of a cascade of cellular events initiated by either infectious or noninfectious inflammatory stimuli. An elevated level of proinflammatory mediators combined with a decreased expression of anti-inflammatory molecules is a critical component of lung inflammation. Expression of proinflammatory genes is regulated by transcriptional mechanisms. Nuclear factor-ka...
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...
INTRODUCTION Since the NF-κB pathway regulates both inflammation and host defense, it is uncertain whether interventions targeting NF-κB would be beneficial in sepsis. Based on the kinetics of the innate immune response, we postulated that selective NF-κB inhibition during a defined time period after the onset of sepsis would reduce acute lung injury without compromising bacterial host defense....
