Abstract

The total activity of lactate dehydrogenase (LDH) and the percentage distribution of its isoenzymes in the tissues and sera of clinically normal adult dogs are presented. Total LDH activity was greatest in skeletal muscle followed by heart muscle, kidney, small intestinal mucosa, liver, lung, pancreas and bone. Each tissue had a unique isoenzyme pattern and the proportions of the isoenzymes in serum suggested that liver is the source of normal serum LDH. The tissue isoenzyme patterns were similar to those obtained by other authors in human beings, horses, cattle, sheep and cats although in liver, differences between ruminants and monogastric animals including dogs were evident. The data presented provide a basis for the interpretation of serum LDH isoenzyme patterns in canine disease.
