Tissue disposition of carbon disulfide: I. Whole-body autoradiography of 35S- and 14C-labelled carbon disulfide in adult male mice. 1984

Occupational exposure to carbon disulfide (CS2) is associated with several adverse effects such as neurotoxicity, atherosclerosis, liver injury and endocrinal disturbances. In the present study, the distribution of CS2 and its metabolites after inhalation of 35S- or 14C-labelled CS2 was studied in adult male mice with whole-body autoradiography. CS2 itself was registered in body fat and in well-perfused tissues at survival times up to 2 hours. Very little CS2 was taken up by the brain. The distribution patterns of CS2 metabolites were very different after administration of C35S2 or 14CS2. 35S-Labelled metabolites were initially concentrated in the liver and kidney, but were rapidly eliminated from the body. There was evidence of an extensive metabolic incorporation of sulfur split off from CS2 during its biotransformation. 14C-Labelled metabolites were likewise concentrated in the liver and kidney, but were also observed in large amounts in the nasal mucosa, bronchi, bone, pancreas, thyroid, adrenal cortex and testis. A marked retention of non-extractable 14C-labelled metabolites was seen in the liver and thyroid. The results point to several sites of specific CS2-induced toxicity due to the tissue disposition of metabolites of CS2.

D002246	Carbon Disulfide	A colorless, flammable, poisonous liquid, CS2. It is used as a solvent, and is a counterirritant and has local anesthetic properties but is not used as such. It is highly toxic with pronounced CNS, hematologic, and dermatologic effects.	Disulfide, Carbon
D002250	Carbon Radioisotopes	Unstable isotopes of carbon that decay or disintegrate emitting radiation. C atoms with atomic weights 10, 11, and 14-16 are radioactive carbon isotopes.	Radioisotopes, Carbon
D005612	Freeze Drying	Method of tissue preparation in which the tissue specimen is frozen and then dehydrated at low temperature in a high vacuum. This method is also used for dehydrating pharmaceutical and food products.	Lyophilization,Drying, Freeze,Dryings, Freeze,Freeze Dryings,Lyophilizations
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.

D001345	Autoradiography	The making of a radiograph of an object or tissue by recording on a photographic plate the radiation emitted by radioactive material within the object. (Dorland, 27th ed)	Radioautography
D001646	Bile	An emulsifying agent produced in the LIVER and secreted into the DUODENUM. Its composition includes BILE ACIDS AND SALTS; CHOLESTEROL; and ELECTROLYTES. It aids DIGESTION of fats in the duodenum.	Biliary Sludge,Sludge, Biliary
D013462	Sulfur Radioisotopes	Unstable isotopes of sulfur that decay or disintegrate spontaneously emitting radiation. S 29-31, 35, 37, and 38 are radioactive sulfur isotopes.	Radioisotopes, Sulfur
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
