Practolol when injected alone did not influence survival rate nor did it cause cardiovascular malformations. Probably the most significant result of this study involves the prevention by practolol of aortic hypoplasia and interrupted aortic arch complexes, anomalies frequently induced by isoproterenol when administered at this stage of embryonic chick development. Butoxamine, a beta\u20102 adrenoreceptor antagonist, did not block the overall effect of isoproterenol nearly as effectively as did practolol. Results from the present study suggest that aortic arch anomalies may be induced in embryonic chicks via beta\u20101 adrenoreceptor stimulation. Beta\u20102 receptor stimulation does not appear to be as significantly involved.\n                  <\/jats:p>","DOI":"10.1002\/tera.1420150314","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T10:14:04Z","timestamp":1118484844000},"page":"317-323","source":"Crossref","is-referenced-by-count":20,"title":["The effect of practolol and butoxamine on aortic arch malformation in beta adrenoreceptor stimulated chick embryos"],"prefix":"10.1002","volume":"15","author":[{"given":"Enid F.","family":"Gilbert","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr.","given":"Harold J.","family":"Bruyere","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shizen","family":"Ishikawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias O.","family":"Cheung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard J.","family":"Hodach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,5,17]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"197","article-title":"Recent betaadrenoreceptor stimulants","volume":"5","author":"Brittain R.
