The objective of the present study was to investigate the role of γ-aminobutyric acid type A receptor (GABAAR) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats. Thirty-two male wistar rats were randomly divided into four groups. Rats in the GABA group were pretreated with LPS and GABA, while those in the bicuculline (BIC) group were pretreated with LPS and bicuculline. We assessed the arterial blood gas, dry/wet ratio, and the level of tumor necrosis factor-α (TNF-α), IL-6, malondialdehyde, and superoxide dismutase 6 h after the immunization.
Acute lung injury
The aim of this study was to investigate the influence of ulinastatin (UTI) on high mobility group box 1 (HMGB1), tumor necrosis factor (TNF)-α, and interleukin (IL)-6 expression in acute lung injury (ALI) rats with sepsis caused by cecal ligation and puncture (CLP) surgery, as well as to examine the underlying biological mechanism. Thirty rats were randomly and evenly divided into sham (control), CLP, and CLP + UTI groups.
A mouse model of acute lung injury (ALI) was chosen in this study to explore the key genes and pathways involved in the process of ALI with microarray technology. Gene expression microarray data were downloaded from the Gene Expression Omnibus database. Mice from the experimental group were further divided into 6 subgroups, which received octadecenoate treatments for 1, 1.5, 3, 4, 18, and 24 h. Differentially co-expressed genes were screened to uncover the pathogenesis of ALI. Almost all of the differentially co-expressed genes were identified at two times: 1.5 and 3 h.
