Biochemical alterations in skeletal muscle induced by 2,4-dichlorophenoxyacetic butyl ester during chick embryonic development.
Biochem. Pharmacol. 40(11) , 2433-40, (1990) 2,4-Dichlorophenoxyacetic butyl ester (2,4-D b.e.) (3.1 mg/egg) was applied on fertile hen eggs before starting the incubation. Chicks hatched from treated eggs showed motor dysfunctions, postural troubles and edematous muscles. The electromyography revealed ... |

Formulation and food deprivation affects 2,4-D neurobehavioral toxicity in rats.
Neurotoxicol. Teratol. 9(5) , 363-7, (1987) The herbicide 2,4-Dichlorophenoxyacetic acid (2,4-D) is a commonly used herbicide and one component of Agent Orange. The herbicide is commonly formulated as the butyl ester. The effects of a 50:50 mixture of n-butyl and iso-butyl esters of 2,4-D (2,4-D mixed ... |

Neurobehavioral toxicity of 2,4-D-n-butyl ester (2,4-D ester): tolerance and lack of cross-tolerance.
Neurotoxicol. Teratol. 10(1) , 75-9, (1988) Daily administration of 2,4-dichlorophenoxyacetic acid-n-butyl ester to rats (2,4-D ester, 150 mg/kg/day SC) initially produced depressions in photocell locomotor activity and increases in landing foot splay. Maximal tolerance developed to these effects follo... |

Nucleic acid content and residue determination in tissues of chicks born from 2,4-dichlorophenoxyacetic butyl ester treated eggs.
Drug Chem. Toxicol. 10(3-4) , 339-55, (1987) The effects of 2,4-dichlorophenoxyacetic butyl ester (2,4-D b.e.) on protein and nucleic acid contents of different tissues of chicks born from externally treated hen's eggs were studied. Residues of 2,4-D b.e. were also determined and quantified by gas liqui... |

2,4-D-n-butyl ester (2,4-D ester) induced ataxia in rats: role for n-butanol formation.
Neurotoxicol. Teratol. 10(1) , 81-4, (1988) Three formulations of 2,4-D were tested in rats for their ability to increase landing foot splay, a measure of ataxia. When administered for three to four consecutive days, 2,4-D-n-butyl ester (150 mg/kg/day SC) produced significant increases in landing foot ... |

Chick brain hypomyelination produced by 2,4-dichlorophenoxyacetic butyl ester treatment.
Neurotoxicology 6(3) , 133-7, (1985) Fertilized hens' eggs were externally treated with 2,4-dichlorophenoxyacetic (2,4-D) butyl ester (2.4 mg/egg) before starting incubation. The specific activity of 2',3'-cyclic nucleotide 3'-phosphohydrolase (CNPase) was diminished in the whole brain of animal... |

Effects of 2,4-dichlorophenoxyacetic acid butyl ester on chick liver.
Arch. Environ. Contam. Toxicol. 25(2) , 204-11, (1993) Fertilized hen eggs were externally treated with 3.1 mg 2,4-dichlorophenoxyacetic acid butyl ester (2,4-D ester) before starting incubation. Liver lipid composition, (14C)2,4-dichlorophenoxyacetic acid (14C-2,4-D) subcellular distribution and covalent binding... |

Penetration studies and residue determinations of 2,4-dichlorophenoxyacetic acid butyl ester in fertile hen eggs and chicks hatched from treated eggs.
Drug Chem. Toxicol. 12(2) , 137-46, (1989) Fertilized hen eggs were topically applied with 2,4-Dichlorophenoxyacetic acid butyl ester (3.1 mg/egg) before starting incubation. During the incubation time 20% of the compound applied on eggs was lost by volatilization. At different incubation times (0, 1,... |

Neurotoxicity of 2,4-dichlorophenoxyacetic butyl ester in chick embryos.
Neurochem. Res. 18(3) , 353-9, (1993) Fertilized hens' eggs were externally treated, before starting incubation, with a single dose of 2,4-Dichlorophenoxyacetic butyl ester (2,4-D b.e., 3.1 mg/egg). Chicks at different developmental stages were examined, extending from 10 day embryos to one day a... |
