[Enzyme activities of beta-hexosaminidase in urine from patients with renal diseases (author's transl)].

Enzymatic activities of beta-hexosaminidase and beta-galactosidase were determined in 24 h urine specimens from patients with renal diseases, from individuals with essential hypertension and patients with other diseases. Patients suffering from various renal diseases had significantly higher activities of the beta-hexosaminidase than individuals with essential hypertension or other diseases. However for beta-galactosidase only the mean value of the enzymatic activities was elevated. The possible mechanisms causing an increase of these enzymes in 24 h urine samples are discussed.
