Changes in carbohydrate metabolism of Pila globosa in response to crustacean hyperglycemic hormone.

Hyperglycemia was caused in the snail Pila globosa by the injection of the hyperglycemic hormones obtained from fresh water crabs (Oziotelphusa senex senex) and marine tiger prawns (Penaeus monodon). Tissue glycogen and total carbohydrates presented a significant decrease which indicated that the source of hyperglycemia was the tissue carbohydrates. The hyperglycemic principles also increased the tissue phosphorylase activity and provided evidence for a possible action of the crustacean hyperglycemic hormones in non-arthropod species.
