ABSTRACT
Lead (Pb) is a corrosion-resistant, heavy, non-ferrous metal. Several metal chelators have been used for the treatment of Pb poisoning. However, the efficacy of sodium para-aminosalicylic acid (PAS-Na) in enhancing Pb excretion has yet to be fully characterized. Healthy male mice (90) were divided into six groups, the normal control group was intraperitoneally (i.p.) injected with saline and the remaining group of mice i.p. 120 mg/kg Pb acetate. Four hour later, mice were subcutaneously (back) injected (s.c.) with (80, 160, 240 mg/kg) PAS-Na or 240 mg/kg edetate calcium disodium (CaNa2EDTA) or an equivalent amount of saline, once per day for 6 days. After 24-h urine sample collections, the animals were anesthetized with 5% chloral hydrate and sacrificed in batches on the 2nd, 4th, or 6th day. Levels of Pb [including manganese (Mn) and copper (Cu)] in the urine, whole blood, and brain tissues were analyzed by graphite furnace atomic absorption spectrometry. The results showed that Pb exposure increased its levels in urine and blood, and PAS-Na treatment may afford antagonistic effect on Pb poisoning, suggesting that PAS-Na is a potentially effective treatment to promote excretion of Pb.
