Foetal accumulation of [14C] carbaryl in rats and mice. Autoradiographic study. 1977

C Declume, and P Benard

Pregnant female rats and mice (18th day) received orally 10 mg/kg of 1-naphthyl-N-methyl-[14C]-carbamate (carbaryl), an anticholinesteratic drug. Animals were sacrificed 1, 5, 8, 24, 48, 72 and 960 h after administration and whole-body autoradiography was performed. Autoradiograms of the uterine cavity indicate a placental transfer and a foetal fixation of [14C] carbaryl metabolites. 14C-activity can be clearly seen in the foetus from the fifth hour; it persits till birth. We found 14C-activity in mice 60 h after birth. In both species there are some sites of accumulation in the foetal tissues, mainly in the eyes, central nervous system and liver.

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
D012721	Carbaryl	A carbamate insecticide and parasiticide. It is a potent anticholinesterase agent belonging to the carbamate group of reversible cholinesterase inhibitors. It has a particularly low toxicity from dermal absorption and is used for control of head lice in some countries.	1-Naphthyl-N-methylcarbamate,Antigale,Carbaril,Carbaryl, Manganese (2+) Salt,Carbaryl, Nickel (2+) Salt,Carbyl,Carylderm,Concentrat VO 18,Dog-Net Insecticide Poudre,Fido's Free-Itch,G-Wizz,Joseph Lyddy,Océcoxil,Poudre insecticide Moureau,Poudre insecticide Vetoquinol,Poutic,Sevin,Skatta Tick Flea Louse Powder,Sépou,Tigal,Dog Net Insecticide Poudre,DogNet Insecticide Poudre,Fido's Free Itch,Fido's FreeItch,G Wizz,GWizz,Lyddy, Joseph,Moureau, Poudre insecticide,VO 18, Concentrat,Vetoquinol, Poudre insecticide,insecticide Moureau, Poudre,insecticide Vetoquinol, Poudre
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

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
