Abstract

Urine, renal and thoracic duct lymph were collected in dogs before and after clamping both renal arteries. After 30 minutes of renal ischaemia there was a marked increase in concentration of cyto­ plasmic enzymes in renal lymph and urine. Less prominent rises also were observed in plasma and thoracic duct lymph.

After 2 hours of ischaemia in addition to further increase in concentration of cytoplasmic enzymes a rise in activities of mitochondrial (GPT, alc. phosphatase, arylamidase) and lysosomal (acid phos­phatase) enzyines was observed in urine and renal lymph. In some animals a significant arterial-renal venous difference was found in LDH concentration, and in renal lymph the LDH isoenzyme pattern shifted towards more slowly migrating M subunits.

There was marked parallelism between enzyme concentrations in renal lymph and urine.

It is concluded, that determination of intracellular enzymes in renal lymph and urine affords a method to assess severity of ischaemic cell damage in the kidney.
