Experimental studies have been carried out to evaluate the effects of carbaryl (l.-naphthyl-methyl-carbamate)- an anticholinesterase pesticide - on the morphogenesis and development of the chick embryo. A solution containing 0.5 mg of carbaryl has been injected in the allantoic sac of the embryos treated (n = 130), at the 5th or 6th incubation day. In comparison with a control group (= 70), some morphological alterations have been found in the embryos treated, at the expense of the skeleton apparatus, particularly in the most distal portions of the lower limbs, as tibial and metatarsal angulations, with their curtailment. Such effects might be related to an interference in the synthesis of NAD (nicotinamide-adenine-dinucleotide), as reported for other organophosphoric pesticides.

D002642 Chick Embryo The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching. Embryo, Chick,Chick Embryos,Embryos, Chick

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
