Abstract

Abstract

The regulation of three biogenic amines over the reproductive neuroendocrine activity of male Scylla serrata was investigated by invivo injection and invitro incubation.The testicular index,the ratio of the mature sections among the seminiferous tubules,and the ratio of Type Bcells among the androgenic glandular cells were taken as the quantitative indexes.In vivo injections indicated that:5-HT can significantly promote the testicular development and the secretion of the androg enic gland in S.serrata;DA can inhibit the testicular development,but no influence on the secretion of the androgenic gland is found;no significant difference was observed between the OA-injected group and the concurrent control.In vitro incubations showed that:5-HT can stimulate the secretion of the brain and the thoracic ganglia,thus accelerate that of the androgenic gland;in the OA and the DA groups,however,no significant influence on the secretion of the brain and the thoracic ganglia was observed.As to the optic ganglia,the three biogenic amines hardly have any effects on the secretion.It is the first time for invitro experiments to report the regulation of biogenic amines over the reproductive neuroendocrine of male crustaceans.Our results corrobo rate that 5-HT first activate the brain and the thoracic ganglia to secret GSH,then promote the testicular development through the androgenic gland.
