title: Trace elements analysis of urine and hair in tuberculous pleurisy.
abstract: In this study, copper, zinc, magnesium, manganese, selenium, and iron of urine and hair were measured in the patients with tuberculous (TB) pleurisy (n = 24) and in the control group (n = 20). Selenium, magnesium, and zinc of hair were found to be significantly lower in TB pleurisy cases than those in the control group (p < 0.05, p < 0.001, and p < 0.01, respectively). On the contrary, selenium and magnesium of urine were found to be significantly elevated in TB pleurisy cases than those in the control group (p < 0.05 and p < 0.001, respectively). There was no significant difference in the value of manganese and iron between TB pleurisy and the control group (p > 0.05). Copper level were significantly increased in hair and decreased in urine of the patients (p < 0.01). The occurrence of these abnormalities constitutes new information regarding trace elements in TB pleurisy patients. These results may provide an additional disease correlate for assessing TB pleurisy risk.
