N-acetyl-beta-glucosaminidase activity in normal and malignant leukocytes.

Studies on glucosaminidase; N-acetyl-beta-glucosaminidase in rat kidney.

Studies on glucosaminidase. 2. Substrates for N-acetyl-beta-glucosaminidase.

the oxygen uptake and acetoacetate oxidation when added alone or with fumarate, but not in the presence of a-oxoglutarate. The reasons for these differences are discussed. Anaerobically, relatively slight inhibitions of the reduction of acetoacetate were observed. 6. The oxidation of L( + )-p-hydroxybutyrate is inhibited by dinitrophenol, whereas that of the D(-)-form is not. This is related to...

Normal values for urinary N-acetyl-beta-glucosaminidase excretion in preterm and term babies.

Urinary N-acetyl-beta-glucosaminidase (NAG) excretion was measured in 14 healthy, preterm, male neonates with gestational ages between 32 and 35 weeks. Daily NAG excretion increased significantly during the first four weeks of life. No correlation was observed between urinary NAG:creatinine ratio and postnatal age regardless of whether measurements were taken from the whole 24 hour urine collec...

Is urinary N-acetyl-beta-D-glucosaminidase a marker of urological abnormality in children?

  Abstract   Background: Hydronephrosis is the most common congenital condition that is detected   by prenatal ultrasonography. Moreover, the widespread use of prenatal ultrasonography   results in an increased recognition of fetal hydronephrosis. Prenatal hydronephrosis   is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. The presence of hydronephrosis is not synonymou...

Lysosomal N-acetyl-beta-D-glucosaminidase: interneuronal differences in activity and molecular forms.

The lysosomal N-acetyl-fl-D-glucosaminidase (EC 3.2.1.30) of brain tissue 1~ has been extensively studied in our laboratory 7,15-1s, with particular emphasis on the distinction between its neuronal and glialT,10,19 components. Evidence for two neuron-al components in the immature rat cerebral cortex, each with distinct characteristics, was presented in 1973 (ref. 18). More recently, we demonstr...
