We employed a murine model of unilateral aspiration to compare surfactant synthesis in the injured (I) and noninjured (NI) contralateral lung. Mice were instilled with hydrochloric acid in the right bronchus and, after 18 h, an intraperitoneal dose of deuterated water was administered as precursor of disaturated phosphatidylcholine (DSPC)-palmitate. Selected bronchoalveolar lavage fluid (BALF) was collected at scheduled time points and lungs were removed. We measured DSPC-palmitate synthesis in lung tissue and secretion in BALF by gas chromatography-isotope ratio mass spectrometry, together with total proteins and myeloperoxidase activity (MPO) by spectrophotometry. BALF total proteins and MPO were significantly increased in the I lungs compared with NI and na\u00efve control lungs. The DSPC pool size was significantly lower in the BALF of the I lungs compared with na\u00efve controls. DSPC synthesis was accelerated in the I and NI lungs. DSPC secretion of the I lungs was similar to their respective na\u00efve controls, and it was markedly lower compared with their respective NI contralateral lungs. DSPC synthesis and secretion were faster, especially in the NI lungs, compared with na\u00efve control lungs, as a possible compensatory mechanism due to a cross-talk between the lungs triggered by inflammation, hyperventilation, and\/or undetermined type II cell reaction to the injury.<\/jats:p>","DOI":"10.1152\/japplphysiol.01535.2012","type":"journal-article","created":{"date-parts":[[2013,12,13]],"date-time":"2013-12-13T05:14:05Z","timestamp":1386911645000},"page":"210-215","source":"Crossref","is-referenced-by-count":9,"title":["Pulmonary surfactant synthesis after unilateral lung injury in mice"],"prefix":"10.1152","volume":"116","author":[{"given":"Giulia","family":"Lamonica","sequence":"first","affiliation":[{"name":"Department of Woman and Child Health, University of Padova, Padova, Italy;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Amigoni","sequence":"additional","affiliation":[{"name":"Department of Emergency, S.
