Occupational exposure to carbon disulfide (CS2) has been associated with an increased rate of spontaneous abortions. Animal experiments have shown that CS2 is embryotoxic and teratogenic. In the present study, the embryonal and foetal distribution of CS2 and its metabolites was studied after administration of 35S- or 14C-labelled CS2 to pregnant mice in different stages of gestation. CS2 and its metabolites passed the placenta at all stages of gestation. High levels of metabolites of CS2 were registered in the embryonic neuroepithelium. In mid and late gestation CS2 itself accumulated in the cerebrospinal fluid (CSF) of the brain. 14C-labelled metabolites of CS2 showed affinity for bone and were retained in the liver even at long survival times (24 hours). These localizations may be of significance for some of the reported teratogenic effects of CS2, such as hydrocephalus, ossification defects and foetal liver injury, and support the idea that CS2 and/or its metabolites are embryotoxic and teratogenic by acting directly on embryonal and foetal structures.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
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

D005333	Fetus	The unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. In humans, the unborn young from the end of the eighth week after CONCEPTION until BIRTH, as distinguished from the earlier EMBRYO, MAMMALIAN.

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
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
