    Abstract:
    OBJECTIVE: To study the early indicators for renal damages in mercury workers and the clinical significance. METHODS: Eighty-five mercury workers were divided into 2 experimental groups: the normal & subject-under-surveillance group and the mercury-poisoning group. Sixty-five healthy adults with no mercury exposure history were assigned as the control group. Any subjects with history of renal diseases or concurrent renal diseases were excluded. The results from physical examinations and measurements of HgU, B-Cr, U-Cr, BUN, N-acetyl-beta-D-glucosaminidase (NAG), beta2-microglobulin (beta2-MG), urinary alpha1-microglobulin (alpha1-MG), and retinol-binding protein (RBP) in all the groups were analyzed. RESULTS: The levels of HgU, NAG, alpha1-MG, beta2-MG, and RBP were significantly higher in the experimental groups than in the control group. The levels of NAG, beta2-MG and RBP were significantly higher in the nomal & subject-under-surveillance group than in the control group. However, there was no statistically significant difference between the levels of B-Cr and BUN in the experimental groups and those of the control group. CONCLUSIONS: Long-term exposure to mercury can cause renal damages. The level of NAG, alpha1-MG, beta2-MG, and RBP can be used as sensitive indicators for detecting early renal damages caused by mercury.
