摘要: The osmoregulatory and metabolic role of testosterone (T) in the euryhaline teleost Sparus auratus was examined. Fish were implanted with a slow-release coconut oil implant alone (control) or containing T (2 5microgg(-1) body weight) sampled 1, 3, 7 days after implantation. Gill Na(+),K(+)-ATPase activity increased fish treated lower dose treatment. Kidney enhanced at first day post-implantation group higher but values diminished by 3. Plasma levels metabolites (glucose, lactate, triglyceride, protein) This availability plasma reflected several changes within different tissues T-treated such as (i) glycogen capacity for gluconeogenesis, ketogenesis, glucose exporting, amino acid catabolism liver, (ii) lipogenic gills, (iii) oxidizing acids kidney, (iv) glycogen, aceotacetate, triglycerides, phosphorylating brain. These results provide evidence regarding an S. that could be related to both processes during sexual maturation.
