Tissue Sources and Diagnostic Value of Circulating Enzymes in Cetaceans
Tissue activities of alanine aminotransferase (AlAT), aspartate aminotransferase (AspAT), sorbitol dehydrogenase (SDH), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), and creatine kinase (CK) were determined in three cetacean species: the bottlenosed dolphin, Tursiops truncatus, belug...
