[Several synovial enzymes in rheumatoid arthritis]

The authors show that although the enzyme variations are nil or unimportant in the mechanical joint fluids, they are of some importance in the inflammation fluids, particularly in cases of rheumatoid arthritis. Of those studied so far, the variations are most notable in the dehydrogenases and the phosphatases, the variations being highly significant and related to one another and to the sedimentation rate.
