Ammonia, urate and nitrite, expected to be the nitrogenous end-products of both <i>Riftia</i> and its symbionts were measured in deep-frozen blood samples and whole animals. The mean concentrations obtained in micromol per liter were all converted to microg N g super(-1) tissue wet weight, or microg N ml super(-1). Ammonia was present in all studied body compartments and appeared to be the prevailing nitrogenous end-product: from 25 to 65 microg N- NH sub(4) super(+) g super(-1) tissue in gill or body wall and trophosome respectively and, around 2 - 4 microg NH sub(4) super(+) g super(-1) in circulating fluids. Urate level was high in the trophosome (17.2 microg N-urate g super(-1)) and occasionally present in the body wall (0 - 4.9 pg N-urate g super(-1)). It was detected neither in the gill nor in circulating fluids. Nitrites were present in the studied body compartments and were largely prevailing in trophosome (1.06 microg N-NO2 super(-) g super(-1)). In contrast to ammonia and urate, nitrite appeared to be negatively affected by the deep freezing/thawing process, as shown by changes in NO2 super(-) content of crab haemolymph submitted to the same treatment as the <i>Riftia</i> blood samples. Therefore, the low nitrite content of blood (9.8 +-2.0 microM, n = 8) could be a result of this unavoidable process. Nitrite measurement on freshly collected animals appears to be necessary. Whether the measured ammonia is the end-product of the tubeworm or that of the endosymbiont is discussed.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Nitrogenous metabolites in tissues and circulating fluids of <i>Riftia pachyptila</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2004-09-20","DateCreate":"2004-09-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":66292,"PubliDate":1997,"Pagination":"122","XtraPublOfAnaID":null,"ISBN":null,"Volume":"38","Issue":"2","BRefMon":66251,"BRefMonRR":"(1997).
