[Alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamate dehydrogenase (GLDH), alkaline phosphatase (AP) and gamma-glutamyltransferase (GGP) in intestinal diseases of dogs]

Abstract

331 dogs, suffering from different intestinal diseases with diarrhea, were classified into the groups of "acute noninfectious", "infectious", "chronic" and "secondary enteropathies". The serum enzymes ALT, AST, GLDH, AP and GGT were determined. In all groups increases of enzyme activities were to be found. The highest and most frequent increases have been observed in acute noninfectious and in secondary enteropathies. The enzyme pattern in acute noninfectious enteropathies indicate a secondary liver disturbance in consequence of the intestinal disease, whereas the liver participation in secondary enteropathies is the effect of the primary disease other than intestinal disturbances. In comparison to this the height and number of increases of liver enzyme activities were low in acute infectious and in chronic enteropathies.
