Sodium dimercaptosuccinate (Na-DMS) ip 1 g.kg-1, dimercaptosuccinic acid (DMSA) ig 1 g.kg-1, DMSA ig 1 g.kg-1 with NaHCO3 or Na-citrate ig 3 g.kg-1 was given to mice, separately. It enhanced the excretion of 210Pb in urine about 3.4, 3.8, 3.6, and 2.3 times vs control, respectively within 24 h. It enhanced the excretion of 203Hg in urine about 2.4, 2.3, 3.3, and 2.7 times, respectively within 24 h. Fecal excretion was not significantly elevated vs control. Tissue radioactivities showed a remarkable decrease in the levels of 210Pb and 203Hg in most organs, but DMSA increase the 210Pb content in kidney. The therapeutic effect of ig DMSA was similar to that of ip sodium dimercaptosuccinate.

UI MeSH Term Description Entries
D007854 Lead A soft, grayish metal with poisonous salts; atomic number 82, atomic weight 207.2, symbol Pb.
D007855 Lead Poisoning Poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of LEAD or lead compounds. Poisoning, Lead,Lead Poisonings,Poisonings, Lead
D008297 Male Males
D008628 Mercury A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
D008630 Mercury Poisoning Poisoning that results from chronic or acute ingestion, injection, inhalation, or skin absorption of MERCURY or MERCURY COMPOUNDS. Poisoning, Mercury,Mercury Poisonings,Poisonings, Mercury
D004113 Succimer A mercaptodicarboxylic acid used as an antidote to heavy metal poisoning because it forms strong chelates with them.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014018 Tissue Distribution Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios. Distribution, Tissue,Distributions, Tissue,Tissue Distributions
