Crustacean hyperglycemic hormone induced alterations in millepede (Spirostreptus asthenes) carbohydrate metabolism.
Following intersegmental injection of the hyperglycemic hormone (HGH) obtained from fresh water crab (Oziotelphusa senex senex) and marine tiger prawn (Penaeus monodon), hemolymph sugar concentration was significantly increased in millepede (Spirostreptus asthenes). Glycogen and total carbohydrates of fat body decreased in injected animals indicating that the source of hyperglycemia was carbohydrates from the fat body. Correlating with the decreased glycogen content, phosphorylase activity of the fat body was elevated. The results strongly suggest that crustacean hyperglycemic hormone exerts influence on non-crustacean species also.
