TI  - Ultrastructural and histochemical study on the interrenal cells of the male 
      stickleback (Gasterosteus aculeatus, Teleostea), in relation to the reproductive 
      annual cycle.

AB  - The steroidogenic interrenal cells in the adrenal homologue of the male 
      stickleback (Gasterosteus aculeatus) were studied in relation to the reproductive 
      cycle by means of histological and ultrastructural observations, and using 
      histochemical methods for the localisation of 3beta-hydroxysteroid dehydrogenase 
      (3betaHSD) and 17beta-hydroxysteroid dehydrogenase (17betaHSD). To determine the 
      various stages of the reproductive cycle, the testes were also examined by 
      histological and histochemical methods (3betaHSD). The results indicate that in 
      this teleost the interrenal cells can undergo a cycle in which phases 
      characterised by different cytological aspects are observed. During this cycle 
      there is a renewal of organelles, in particular mitochondria and SER. Periodic 
      degenerative processes are also found. Organelle cytology showed that the cell 
      cycle has at least 3 different aspects during the year. An analogy with some 
      cytological aspects of the adrenal zonation in mammals is possible. It is 
      postulated that the interrenal gland activity could substitute or supplement 
      androgen production by the testes.
