ABSTRACT

Ganoderma lucidum is a hard, bitter mushroom with many ethnomedicinal uses, including conditions similar to lead (Pb) toxicity. The aim of this study was to evaluate the protective effects of a G. lucidum aqueous extract (GL) when concurrently administered with Pb. Adult Wistar rats were administered oral doses of Pb (100 mg/kg) daily for 25 consecutive days. Of the Pb-treated rats, 3 groups received 100, 200, or 400 mg/kg/day GL, respectively; one group was given only 50 mg/kg/day 2,3-dimercaptosuccinic acid (DMSA); and another group was given 400 mg/kg/day GL and 50 mg/kg/day DMSA. Body weight, Pb levels in organs, enzyme and lipid levels in serum, and antioxidant capability were evaluated. Body weights were not significantly altered by GL. All doses of GL significantly reduced the amount of Pb in the liver (P < 0.01) and kidneys (P < 0.05), but not in the spleen. Doses of GL significantly reduced (P < 0.05) amounts of low-density lipoprotein, but not high-density lipoprotein or triglycerides, in serum. Pb-induced increases in amounts of serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase were significantly (P < 0.01) attenuated by GL. Also, a Pb-induced reduction in the amount of superoxide dismutase was significantly (P < 0.05) reversed, but the nitric oxide level was not significantly elevated. An increased malondialdehyde level, which had been induced by Pb, was significantly (P < 0.01) reversed. In conclusion, GL protects against some of the deleterious effects of Pb ingestion, possibly through antioxidant and other mechanisms. DMSA did not enhance the beneficial effects of GL.
