Changes in N-Acetyl-β-D-Glucosaminidase Activity in the Urine and Urinary Albumin Excretion in Magnesium Deficient Rats

Abstract

  To discover the details of the effects of magnesium (Mg) deficiency on kidney function, the course of changes in N-acetyl-β-D-glucosaminidase (NAG) activity in the urine and in urinary albumin excretion were examined in rats fed a Mg-deficient diet. NAG activity in the urine and urinary albumin excretion in rats fed the Mg-deficient diet significantly increased from 7 d until the end of the feeding period. We suggest that Mg-deficient diet rapidly induces kidney function insufficiency.
