The authors compared histories of nonmalignant respiratory diseases (asthma, bronchitis, emphysema, hay fever, and pneumonia) in 1,553 lung cancer patients and 1,375 healthy controls enrolled in a Texas case-control study from 1995 to 2003. They incorporated data on two biologically relevant polymorphic genes, matrix metalloproteinase-1 and myeloperoxidase. Emphysema was associated with a stati...

amiodarone is used in treatment of cardiac arrhythmias. therapeutic use of amiodarone is limited by its side effects, including pulmonary toxicity. human placenta extract (hpe) contains a variety of bio-active substances. thus, the present study aimed to quantitatively evaluate the protective effects of hpe on the structural lung changes induced by amiodarone using stereological methods. spragu...

Infrarenal aortic cross-clamping (IAC) is commonly used during infrarenal vascular operations. Prolonged IAC causes ischemia-reperfusion injury to local tissues, resulting in the release of inflammatory cytokines and acute lung injury (ALI). Pentoxifylline (PTX) is a clinically used drug for chronic occlusive arterial diseases and exerts protective effects against ALI induced by various factors...

In this study, we examined the effect of invariant natural killer T (iNKT) cells on the function of lung dendritic cells (LDCs) in eliciting protective immunity against Chlamydia pneumoniae (Cpn) lung infection. We employed a combination of approaches including the use of iNKT cell-deficient, Jα18-knockout (KO) mice and LDC adoptive transfer. We found that iNKT cells significantly altered the n...

Increased endothelial cell (EC) permeability and vascular inflammation along with alveolar epithelial damage are key features of acute lung injury (ALI). Products of 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine oxidation (OxPAPC) showed protective effects against inflammatory signaling and vascular EC barrier dysfunction induced by gram-negative bacterial wall lipopolysaccharide (L...

OBJECTIVE To determine whether anaesthetised patients undergoing surgery could benefit from intraoperative protective ventilation strategies. METHODS MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) were searched up to February 2014. Eligible studies evaluated protective ventilation versus conventional ventilation in anaesthetised patients without lung injury at th...
