Lung injury such as pneumothorax now can be diagnosed reliably, portably and quickly. Vibro-acoustic waves are sent through the chest and the resulting wave is measured. By analyzing attenuation characteristics determined by the geometry of the chest structures, a determination can be made of whether the patient's pleural space is healthy, contains air (pneumothorax) or contains fluid (hemothorax).

We disclose a new and useful biomarker for acute kidney injury (i.e., AKI), renal ischemia reperfusion injury (i.e., IRI), ischemic acute kidney injury, and/or ischemic acute tubular necrosis (i.e., ATN). The biomarker is GRO-alpha (i.e., CXCL1, chemokine C-X-C ligand 1, GRO1, GROa, MGSA, MGSA alpha, MGSA-a, NAP-3, SCYB1). We detected the biomarker using a QUANTIKINE® human GRO-alpha immunoassay (Cat. No. DGR00, R & D Systems, Minneapolis, Minn.). In addition, we disclose a method of treating lung damage.

A process and a device is presented with an electro-impedance tomography (EIT) system (2), with a computing unit (4) and with a respirator (1) for gentle mechanical lung ventilation especially in case of atelectases following surgical procedures. A first image of the healthy lungs is first recorded prior to anesthetization by means of the EIT system (2) and the total area and/or the spatial distribution of ventilated lung areas are determined from the image values by means of the computing unit (4). Second or additional status images are recorded after assumed lung damage and the total area and/or the spatial distribution of ventilated lung areas are determined. The total areas and/or the spatial distribution of the ventilated lung areas from the first and second or further status images are compared by means of the computing unit (4) and analyzed for the presence of lung areas that have no or reduced ventilation due to atelectases. The information on the presence, the extent and/or the spatial distribution of atelectases is sent by the EIT system (2) to the respirator (1) so that the respiration pressure is increased step by step by the respirator (1) as a function of the status image or the currently determined status images until the current image of the lung status corresponds to the first status image or comes close to it with minimal deviations. The respiration pressure is subsequently reduced again step by step by the respirator (1) until the computing unit (4) detects a reduction of the ventilated lung areas and the respiration pressure is subsequently increased again by means of the respirator (1) to the last value at which no change occurred in the ventilated lung areas.

During lung injury, p53 expression increases, inducing plasminogen activator inhibitor-1 (PAI-1) while inhibiting expression of urokinase-type plasminogen activator (uPA) and its receptor (uPAR), resulting in apoptosis of lung epithelial cells (LECs). In the bleomycin lung injury model, p53 and PAI-1 are induced while uPA and uPAR are inhibited. A 20 residue peptide DGIWKASFTTFTVTKYWFYR termed PP-1 (the Cav-1 scaffolding domain) or peptide NYHYLESSMTALYTLGH, termed PP-2, protected LECs from bleomycin-induced apoptosis in vitro and in vivo and prevented subsequent pulmonary fibrosis by attenuating lung epitheilial damage. Pharmaceutical compositions, peptide multimers and deliverable polypeptides comprising the above peptides are dislcosed. The peptides and functional variants, peptide multimers, cell-targeted polyepeptides and pharmaceutical compositions are used in methods for inhibiting apoptosis of injured or damaged lung epithelial cells and for treating acute lung injury and consequent pulmonary fibrosis.
