Thrombin (1 and 10 U\/ml) reduced basal tone and significantly inhibited the contractions elicited by K\n +<\/jats:sup>\n , PGF\n 2\u03b1<\/jats:sub>\n , and plasmin. The relaxant effect of thrombin was abolished by procedures that destroy endothelium and by exposing the artery to thrombin for prolonged periods (tachyphylaxis). AT III (1\u20136 U\/ml) reduced basal tone and significantly inhibited, in a concentration-dependent manner, the contractile responses to K\n +<\/jats:sup>\n , 5-HT, PGD\n 2<\/jats:sub>\n , PGF\n 2\u03b1<\/jats:sub>\n , and plasmin. In sharp contrast to thrombin, AT III did not induce tachyphylaxis nor was its vasorelaxant effect significantly reduced by destruction of the endothelium. The results show AT III to be a potent and nonspecific inhibitor of human cerebral arteries and support the hypothesis that AT III may contribute to the delay of cerebral vasospasm seen in patients who experience aneurysmal hemorrhage.\n <\/jats:p>","DOI":"10.1038\/jcbfm.1987.10","type":"journal-article","created":{"date-parts":[[2011,4,8]],"date-time":"2011-04-08T00:44:28Z","timestamp":1302223468000},"page":"68-73","source":"Crossref","is-referenced-by-count":26,"title":["Comparison of the Inhibitory Effects of Antithrombin III, \u03b1\n 2<\/sub>\n -Macroglobulin, and Thrombin in Human Basilar Arteries: Relevance to Cerebral Vasospasm"],"prefix":"10.1177","volume":"7","author":[{"given":"Richard P.","family":"White","sequence":"first","affiliation":[{"name":"Departments of Pharmacology and Neurosurgery, University of Tennessee Medical Center, Memphis, Tennessee, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1987,2,1]]},"reference":[{"key":"bibr1-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1974.40.4.0433"},{"key":"bibr2-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1005058"},{"key":"bibr3-jcbfm.1987.10","first-page":"144","volume-title":"Cerebral Arterial Spasm","author":"Blaso WP","year":"1980"},{"key":"bibr4-jcbfm.1987.10","doi-asserted-by":"crossref","first-page":"166","DOI":"10.1016\/S0022-3565(25)33169-1","volume":"222","author":"De Mey JG","year":"1982","journal-title":"J Pharmacol Exp Ther"},{"key":"bibr5-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1005059"},{"key":"bibr6-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-197711000-00004"},{"key":"bibr7-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-198001000-00001"},{"key":"bibr8-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.pa.24.040184.001135"},{"key":"bibr9-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.10.3.306"},{"key":"bibr10-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.55.5.575"},{"key":"bibr11-jcbfm.1987.10","first-page":"257","volume":"11","author":"Kwak R","year":"1979","journal-title":"Surg Neurol"},{"key":"bibr12-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1016\/0090-3019(85)90303-9"},{"key":"bibr13-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1007\/BF01401633"},{"key":"bibr14-jcbfm.1987.10","first-page":"H267","volume":"232","author":"Toda N","year":"1977","journal-title":"Am J Physiol"},{"key":"bibr15-jcbfm.1987.10","first-page":"H145","volume":"243","author":"Toda N","year":"1982","journal-title":"Am J Physiol"},{"key":"bibr16-jcbfm.1987.10","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.17.2.207"},{"key":"bibr17-jcbfm.1987.10","first-page":"27","volume":"16","author":"White RP","year":"1985","journal-title":"Neurosurgery"},{"key":"bibr18-jcbfm.1987.10","first-page":"12","volume":"21","author":"White RP","year":"1984","journal-title":"Blood Vessels"},{"key":"bibr19-jcbfm.1987.10","doi-asserted-by":"crossref","unstructured":"White RP, Macleod RM, Muhlbauer MS, (1986) Evaluation of the role hemoglobin in CSF plays in producing contractions of cerebral arteries.
