Description
Summary:Stimulation of ovarian growth was accomplished by administration of leucine-enkephalin in the fresh water field crab Oziotelphusa senex senex. The ovarian index was significantly increased in the crab after leucine-enkephalin injection, but the oocyte diameters were not significantly altered, indicating that leucine-enkephalin stimulated more oocytes to mature. In contrast, injection of methionine-enkephalin significantly decreased the ovarian index and oocyte diameters.
