This study focuses on neutrophil-derived oxidative stress. The influence of (A), continuous hypochlorous acid (HOCl) infusion over 105 min and (B) stimulation of PMN having been delayed in the pulmonary microvasculature were studied. Therefore pulmonary artery pressure (PAP), capillary filtration coefficient (Kf,c), and fluid retention ( \u0394 W) were monitored using isolated rabbit lungs. These models (A\/B) were compared with each other to assess the reproducibility of neutrophil-derived oxidative stress by HOCl. A: Infusion of 250\/500\/1,000\/ 2,000 nmol\/min HOCl (n = 6\/group) evoked a \u0394 PAPmax of 0.4 \u00b1 0.07\/2.4 \u00b1 0.21\/4.9 \u00b1 0.29\/4.6 \u00b1 0.25 mm Hg at 105\/105\/56.4 \u00b1 5.6\/21.5 \u00b1 0.8 min and a tenfold increase in Kf,c\/ \u0394 W at 60 min. B: Stimulation of PMN (1,480 \u00b1 323\/ \u03bc l, n = 8), which were added into the perfusate and sequestrated in the microvasculature, with 1 \u03bc M FMLP resulted in a \u0394 PAPmax = 8.4 \u00b1 1.1 torr (t = 3.7 \u00b1 0.19 min) and a twofold increase in Kf,c\/ \u0394 W (t = 60 min) that were accompanied by a myeloperoxidase (MPO)- release (MPOmax = 56.1 \u00b1 7.3 mU\/l, after 1 to 3 min). There was a strong correlation between \u0394 PAPmax and MPOmax (r = 0.97, p &amp;lt; 0.01). Both models of neutrophil-derived oxidative stress evoked changes in pulmonary circulation providing evidence for an involvement of PMN via their major oxidant HOCl in pulmonary hypertension and edema during ARDS.<\/jats:p>","DOI":"10.1164\/ajrccm.156.3.9608032","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T13:25:01Z","timestamp":1365081901000},"page":"924-931","source":"Crossref","is-referenced-by-count":22,"title":["Comparable Effects of HOCl and of FMLP-stimulated PMN on the Circulation in an Isolated Lung Model"],"prefix":"10.1093","volume":"156","author":[{"given":"STEFAN","family":"HAMMERSCHMIDT","sequence":"first","affiliation":[{"name":"Department of Cardiology and Pulmonology, University G\u00f6ttingen, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HANS","family":"WAHN","sequence":"additional","affiliation":[{"name":"Department of Cardiology and Pulmonology, University G\u00f6ttingen, G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1997,9,1]]},"reference":[{"key":"2026032709221295200_B1","doi-asserted-by":"crossref","first-page":"471","DOI":"10.1164\/ajrccm\/141.2.471","article-title":"Macrophages and polymorphonuclear neutrophils in lung defense and injury.","volume":"141","author":"Sibille","year":"1990","journal-title":"Am.
