Objectives : The aim of this study was assessment of the variation of urinary mercury concentrations after removal of amalgam fillings in children. Methods : 10 elemental school children with amalgam filling tooth surfaces were took part in this study. One dentist recorded the number of amalgam filling surface, and general characteristics of subjects were surveyed by questionnaire. Each urine samples were collected before, immediately after and after 24 hours amalgam removal. The statistical analysis was performed using the SPSS 18.0. Results : The mean concentration urinary mercury immediately after amalgam removal was higher ($5.70{\pm}1.20{\mu}g/g$ creatinine) than before amalgam removal ($5.28{\pm}1.53{\mu}g/g$ creatinine). The mean concentration urinary mercury level whose have 1-10 amalgam removal surfaces was increased after amalgam removal compared with before. Conclusions : Mercury concentration in urine was influenced by amalgam removal.

BACKGROUND: The purpose of this study was that serum metabolic and hematological variables were measured to investigate the detoxication effect of Taraxacum mongolicum extract on male albino rat exposed with lead and mercury. METHODS AND RESULTS: For this study, Pb and Hg-exposed( 50 ppm) albino rats was used, and the treatments were carried out in three doses of 100 mg/kg, 200 mg/kg and 500 mg/kg as dry weight of T. mongolicum extract. T. mongolicum extract could improved the body weight gain and feed efficiency ratio, except to food intake. The levels of biochemical factors elevated by Pb-Hg mix exposure, which are Bilirubin, Alkaline phosphatase(ALP), glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase(LDH), ceatinine and blood urea nitrogen(BUN), were significantly reduced in all treated groups as compared to Pb-Hg mix exposure alone. T. mongolicum extract was shown to suppress the accumulation of Hg and Pb in serum by dose dependent manner. CONCLUSION: Therefore, this study suggest that T. mongolicum extract might have the potential effect to minimize the toxic effects of Pb and Hg.
