The toxicity of heavy metals such as mercury (Hg) in humans and animals is well documented. The kidney is the primary deposition site of inorganic-Hg and target organ of its toxicity. The present study investigated the protective efficacy of flaxseed lignan-Secoisolariciresinol diglucoside (SDG) on nephrotoxicity induced by mercuric chloride (HgCl). Rats were intraperitoneally injected with HgCl(2 mg/kg/day) and renal toxicity was induced. Subcutaneous administration of rats with SDG (5 mg/kg/day) as a pre-treatment caused a significant reversal of HgClinduced increase in blood urea, creatinine, glutathione s-transferase and catalase (CAT). On the other hand, administration of SDG with HgClrestored normal levels of albumin and superoxide dismutase (SOD). Histological examination of kidneys confirmed that pre-treatment of SDG before HgCladministration significantly reduced its pathological effects. Thus, the results of the present investigation suggest that SDG can significantly reduce renal damage, serum and tissue biochemical profiles caused by HgClinduced nephrotoxicity. Hence, SDG may be recommended for clinical trials in the treatment of kidney disorders caused by exposure to Hg.
