Objective:
To explore the correlation among some biochemical indexes in the fluoride workers.
Methods:
The activities of superoxide dismutase(SOD), glutathione peroxidase (GSH-Px), catalase (CAT), alkaline phosphatase (AKP) and the level of calcitonin (CT), parathyroid hormone (PTH), IgG, IgA, IgM, Cu2+, Zn2+, Ca2+, Mg2+ and Se2+, F- in serum and in urine were measured in fifty male fluoride workers and fifty controls.
Results:
The levels of F-, CT, PTH, AKP and GSH-Px in serum and F- in urine in exposed group were significantly different from that in control group. Correlation analysis indicated that F- in urine and CAT(r = 0.3133, P < 0.05), CT and PTH(r = 0.5173, P < 0.01), Se2+ and CAT(r = 0.4354, P < 0.05) were positively correlated. There were significantly negative correlation between F- in serum and GSH-Px (r = -0.5202, P < 0.01) and positive correlation among Cu2+, Zn2+, Ca2+ and Mg2+ in serum.
Conclusion:
(1) Excess of fluoride may affect secretion of calcium adjusting hormone (CT, PTH); (2) Changes of AKP and GSH-Px may be regarded as health monitoring indexes; (3) The correlation of biochemical indexes plays an important role in studying the mechanism and the early prevention and treatment of industrial fluorosis.
