Kinetic rate assay of urinary N-acetyl-beta-D-glucosaminidase with 2-chloro-4-nitrophenyl-N-acetyl-beta-D-glucosaminide as substrate.
In this new procedure for determining the activity of N-acetyl-beta-D-glucosaminidase (EC 3.2.1.30; NAG) in urine, a new synthetic substrate, 2-chloro-4-nitrophenyl-N-acetyl-beta-D-glucosaminide is used. No sample blank is required because the activity is determined kinetically. Very high precision is possible, with CVs of less than 3.8% both within-run and between-run. Glucose, ascorbic acid, bilirubin, bromosulfonphthalein, and phenosulfonphthalein do not interfere. The reference interval (mean +/- 2 SD) for healthy subjects was 1.9-11.1 U per gram of creatinine. NAG activity can be determined over a wide range (2-500 U/L) with high sensitivity. The method is suitable for use with various automated analyzers, and it should be useful for screening for renal diseases.

Malignant thymoma with distant metastases: a case report and review of the literature.
A patient, a 46-year-old female, with a malignant thymoma spreading to the extrathoracic region is described. She underwent a thoracotomy and received radiation therapy, but the myasthenic symptoms did not disappear. A metastatic thymoma of the right mandibula was removed 9 months after thoracotomy. Further examination revealed metastatic thymomas of the bone and liver. After the operation the patient received combination chemotherapy (vincristine, cyclophosphamide, 6-mercaptopurine, prednisone) and remained asymptomatic for 31 months. She was found to have a metastatic thymoma in the occipital lobe of the brain 3.5 years after thoracotomy, and died from infection of the lung. Distant metastases and chemotherapy in malignant thymoma are reviewed.
