N-Acetyl-beta-D-glucosaminidase (NAG) activities in the urine of men and rats were measured with methods recommended as procedures without pretreatment of the urine sample. Four different derivatives of NAG were compared for determination: 4-nitrophenyl; 3,3-dichlorophenylsulfonphthaleinyl; 3-cresolsulfonphthaleinyl, and 2-methoxy-4-(2-nitro-vinyl)phenyl. The conventional test using the 4-nitrophenyl derivative showed the highest activities and correlated very well with the other tests. There… CONTINUE READING
