Mice were exposed to mercuric chloride (HgCl(2)) (1 mg/kg, subcutaneously) for two weeks. After that, mice received (PhSe)(2) (15.6 mg/kg), or DMPS (12.6 mg/kg), or a combination of both for one week. Thiobarbituric acid-reactive substances (TBARS), ascorbic acid and Hg(2+) levels and glutathione S-transferase (GST) and catalase (CAT) activities were carried out in kidney. Hematological parameters, plasmatic billirubin, uric acid, urea and creatinine levels as well as lactate dehydrogenase (LDH) activity were determined. (PhSe)(2) or DMPS restored the increase in LDH activity and TBARS, bilirubin, uric acid, urea and creatinine levels caused by HgCl(2). The levels of erythrocytes, hemoglobin and hematocrit reduced by HgCl(2) exposure were restored by (PhSe)(2) or DMPS administration in mice. Leukocyte and platelet counts modified by HgCl(2) exposure were restored by (PhSe)(2) or DMPS therapy. DMPS restored the increase in Hg(2+) levels induced by exposure to HgCl(2). Concomitant administration of (PhSe)(2) and DMPS reduced the effectiveness of DMPS in restoring damage induced by HgCl(2). Combined therapy with (PhSe)(2) and DMPS was less effective than isolated therapies in restoring the damage induced by HgCl(2) in mice. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
