pubmed-article:6244767 | pubmed:abstractText | The administration of an acute pulmonary edemagenic dose (ip) of thiourea to rats results in an elevation of angiotensin converting enzyme (ACE) in serum, lung lavage, and pleural effusion. The increased serum ACE corresponds to a reduction in lung ACE, but it is transient, lasting between 1 and 2 h. ACE remains elevated in lung lavage and pleural effusion for at least 4 h after the administration of thiourea. | lld:pubmed |
