[Histochemical changes in leukemia in cattle].
Histochemical investigations were carried out to demonstrate the activity of succinic dehydrogenase, diphosphopyridine-nucleotid-diaphorase, alkaline phosphatase, and acid phosphatase in the liver, kidneys, lymph nodes, and heart muscle of a total of 20 cows with positive serologic response for leukosis as well as in organs of 2 normal controls. It was found that the lymphoid cells of the leukotic proliferations and the activated endothelial and adventitial cells of the blood vessels had high alkaline phosphatase activity and negligibly expressed acid phosphatase activity. Dehydrogenase activity was low in the lymphoid-cell proliferations and in the activated cell of the vessels. The cell metabolism of the leukotic proliferations was like-wise disturbed. Histochemical methods of investigations could be used test-like in the diagnosis of bovine leukosis.
