We surgically induced ELH in the right ears of 9 guinea pigs, while the right ears of 6 guinea pigs received a sham operation. The left ears of the 15 animals constituted the normal group. Eight weeks after surgery, summating potential (SP) and action potential (AP) amplitudes were measured prior to and following the administration of glycerol or urea. The SPs and SP\/AP ratios were reduced in all groups, with no significant differences among groups or between dehydrating agents. Some of the hydropic ears, however, did show an increased AP threshold and a recruitment effect. In measurements from 6 additional animals, serum osmolarity increased more with urea than with glycerol. The guinea pig model remains valuable for investigation of ELH, even though it differs in significant respects from ELH in humans.<\/jats:p>","DOI":"10.1177\/000348949710601109","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:38:05Z","timestamp":1412347085000},"page":"934-942","source":"Crossref","is-referenced-by-count":0,"title":["Electrocochleographic Evaluation of the Guinea Pig Model of Endolymphatic Hydrops"],"prefix":"10.1177","volume":"106","author":[{"given":"Mohamed","family":"Badr-El-Dine","sequence":"first","affiliation":[{"name":"Dallas, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George M.","family":"Gerken","sequence":"additional","affiliation":[{"name":"Dallas, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karen S.","family":"Robinson","sequence":"additional","affiliation":[{"name":"Dallas, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles G.","family":"Wright","sequence":"additional","affiliation":[{"name":"Dallas, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William L.","family":"Meyerhoff","sequence":"additional","affiliation":[{"name":"Dallas, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1997,11,1]]},"reference":[{"key":"bibr1-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348946707600311"},{"key":"bibr2-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1016\/0378-5955(84)90071-6"},{"key":"bibr3-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348949110000613"},{"key":"bibr4-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1007\/BF00453491"},{"key":"bibr5-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348948809700111"},{"key":"bibr6-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348949210100212"},{"key":"bibr7-000348949710601109","doi-asserted-by":"crossref","first-page":"200","DOI":"10.1016\/S0196-0709(86)80007-2","volume":"7","author":"Van de Water SM","year":"1986","journal-title":"Am J Otol"},{"key":"bibr8-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1016\/0196-0709(89)90093-8"},{"key":"bibr9-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1016\/0378-5955(92)90044-N"},{"key":"bibr10-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348947308200110"},{"key":"bibr11-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348948609500413"},{"key":"bibr12-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1007\/BF00453702"},{"key":"bibr13-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348948008900408"},{"key":"bibr14-000348949710601109","first-page":"31","volume":"9","author":"Dauman R","year":"1988","journal-title":"Am J Otol"},{"key":"bibr15-000348949710601109","doi-asserted-by":"publisher","DOI":"10.3109\/00016488409132933"},{"key":"bibr16-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1007\/BF00464262"},{"key":"bibr17-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198212000-00008"},{"key":"bibr18-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1981.00790440009002"},{"key":"bibr19-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1016\/0196-0709(93)90006-S"},{"key":"bibr20-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348948509400219"},{"key":"bibr21-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1016\/0378-5955(91)90194-E"},{"key":"bibr22-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1007\/BF00481445"},{"key":"bibr23-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1016\/0378-5955(93)90059-A"},{"key":"bibr24-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348948709600309"},{"key":"bibr25-000348949710601109","doi-asserted-by":"publisher","DOI":"10.1177\/000348949009900714"},{"key":"bibr26-000348949710601109","unstructured":"zum Gottesberge Meyer AM, Mai JK.
