GPT and hydrops fetalis: The same pattern was observed in some of the cellular damage plasma marker levels, with a significant increase of amylase, aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio, AST and creatine kinase (CK) only in HF/DDE animals (interaction; p = 0.0156, p = 0.0376, p = 0.0484 and p = 0.0241, respectively).
