TISSUE ENZYME ACTIVITIES IN KEMP'S RIDLEY TURTLES (LEPIDOCHELYS KEMPII).

This study determined the tissue distribution and activities of eight enzymes in 13 juvenile Kemp's ridley turtles (Lepidochelys kempii) that died after stranding. Samples from the liver, kidney, skeletal muscle, cardiac muscle, pancreas, lung, small intestine, and spleen were evaluated for activities of alanine aminotransferase (ALT), alkaline phosphatase (ALP), amylase, aspartate aminotransferase (AST), creatine kinase (CK), γ-glutamyl transferase (GGT), lactate dehydrogenase (LDH), and lipase. AST, CK, and LDH activities were highest in cardiac and skeletal muscle but were also found in all other tissues. Amylase and lipase activities were highest in the pancreas and low in all other tissues. ALP activity was highest in the lung. ALT activity was highest in liver, kidney, and cardiac muscle, and GGT activity was highest in the kidney, but activities of these enzymes were low in all tissues. These data may assist clinicians in interpretation of plasma enzyme activities of Kemp's ridley turtles.
