The variability might be related to undetermined genetic abnormalities interacting with factors such as gender, weight loss, and vascular injury. We, therefore, assessed the effect of Dex (5 mg \u00b7 kg<jats:sup>\u22121<\/jats:sup>\u00b7 day<jats:sup>\u22121<\/jats:sup>) in female obese rats, designated JCR:LA-cp or cp\/ cp; in lean rats, designated (+\/?); and in normal Sprague-Dawley (S-D) rats under control conditions or after endothelial injury induced by monocrotaline (60 mg\/kg). Pulmonary arterial pressure, right ventricular hypertrophy, percent medial wall thickness of muscular arteries, and muscularization of peripheral arteries were assessed as indexes of PVD. Although Dex reduced weight gain in cp\/ cp and S-D rats ( P &lt; 0.05 for both), it did not cause PVD. Moreover, PVD in S-D rats after monocrotaline injection was paradoxically ameliorated by Dex ( P &lt; 0.05) despite induction of pulmonary artery elastase ( P &lt; 0.05), which we showed is critical in inducing experimental PVD. Thus it is possible that Dex is concomitantly offsetting the sequelae of elastase activity.<\/jats:p>","DOI":"10.1152\/japplphysiol.00500.2002","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:42:35Z","timestamp":1425415355000},"page":"1770-1778","source":"Crossref","is-referenced-by-count":21,"title":["Dexfenfluramine
