Study on Urinary N acetyl β D glucosaminidase(NAG)and Cadmium Metallothionein(Cd MT)in A Population Exposed to Environmental Cadmium

In order to investigate the relationship of urinary cadmium with other indices of renal effects,the samples of 90 cases living in a cadmium-polluted area for more than 30 years were collected. Urinary cadmium、NA G、Cd-MT and creatinine were determined. The result showed that urinary Cd-MT corrrelated with urinary cadmium and NA G.Urinary Cd-MT can be used as a sensitive and spectific indicator of renal damage at early stage urinary of nephrotoxity.
