Corn extracts lower tissue arsenic level in rat

This study was carried out to see whether corn extracts could reduce the accumulation of arsenic in different tissues of rat. Exposure to arsenic (700µg/rat/day) orally for 15 days led to significant accumulation of arsenic and significant reduction in the concentration of reduced glutathione (GSH) in different tissues. While water, salt, ethanol and alkali extracts of corn were co-administered at a dose of 0.5 mL/rat/day orally by stomach tube during last 8 days, arsenic concentration decreased significantly in all tissues and reduced glutathione (GSH) concentration increased significantly in tissues except heart and skin.
