Injection of methionine-enkephalin leads to hyperglycemia and hyperglucosemia in the estuarine crab <i>Scylla serrata</i> in a dose-dependent manner. Decreases in total carbohydrate (TCHO) and glycogen levels of hepato-pancreas and muscle with an increase in phosphorylase activity were also observed in intact crabs after methionine-enkephalin injection. Eyestalk ablation depressed hemolymph glucose (19%) and TCHO levels (22%), with an elevation of levels of TCHO and glycogen of hepatopan-creas and muscle. Tissue phosphorylase activity decreased significantly during bilateral eyestalk ablation. Administration of methionine-enkephalin into eyestalkless crabs caused no significant alterations in these parameters when compared to eyestalk ablated crabs. These results support the hypothesis that methionine-enkephalin produces hyperglycemia in crustaceans by triggering release of hyperglycemic hormone from the eyestalks.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Methionine-enkephalin induces hyperglycemia through eyestalk hormones in the estuarine crab <i>Scylla serrata</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:31:14.875069","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2003-04-04","DateCreate":"2003-04-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000170748600003","VABBcode":null,"OpenAcc":0,"DOI":"10.2307/1543521"},"refs":null,"anarec":{"AnaID":33888,"PubliDate":2001,"Pagination":"17-25","XtraPublOfAnaID":null,"ISBN":null,"Volume":"201","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42437,"SerRR":"The Biological Bulletin.
