Abstract/OtherAbstract:
The goal of the present study was to evaluate the changes in the cell type composition and ATPase activities (total ATPase, ouabain-sensitive Na+/K(+)-ATPase, furosemide-sensitive Na(+)-ATPase) that occur during the different stages of the moulting cycle in the hepatopancreas of the Marsupenaeus japonicus. The results clearly suggest that the number of resorptive and fibrillar cell types changes significantly during the different stages. An inverse correlation between resorptive and fibrillar cells is observed during moulting (both in normally fed and fasted animals). Fasting, but not the moulting cycle, affects the number of blister-like cells. In the resorptive cells the enzymatic activities (total ATPases and ouabain-sensitive Na+/K(+)-ATPase) also change during the moulting in a cyclical manner. All these results are in agreement with and confirm the different functions carried out by the two cell types within the hepatopancreas.
