Origin of Enzymes in Urineood plasma, blood cells, bacteria, epithelium of the urinary tract, and seminal fluid. A classification of diagnostically relevant urinary enzymes according to their origin and handling by the kidney is given in Table 1.

Distribution of Diagnostically Relevant Enzymes Along the Nephronnter the urinary compartment by glomerular filtration, tubular or postrenal release. From the study of renal morphology, biochemistry and function, our knowledge concerning the intranephron and intracellular origin of enzymes has greatly increased over the past decades [15, 31]. Because of their rel

SPASM

Mechanisms of Enzyme Release and Causes of Altered Enzyme Excretion basic principles can be deduced for changes of enzymuria: (a) abnormal composition of the primary urine, independent of the cause for any alterations, which may be pre-renal (e.g., increased level of lysozyme) or renal (e.g., increased glomerular permeability), and (b) structural and functional abe

The cytosolic enzyme, the “classic” leucine aminopeptidase [6], hydrolyzes .-peptides with an N-terminal leucine residue. The recommended substrates are .-leuc

It must be considered that these values may vary significantly due to methodological differences as especially observed in all cases of enzyme activity measurements. Thus, the methods are briefly characterized by

Clinicians demand cost-efficient tests which sensitively and specifically reflect renal function and do not annoy patients.
