Transfer of leptophos in hen eggs and tissues of embryonic rats.
Piao FY, Xie XK, Kitabatake M, Yamauchi T. Piao FY, et al. J Toxicol Sci. 1997 May;22(2):99-109. doi: 10.2131/jts.22.2_99. J Toxicol Sci. 1997. PMID: 9198007
Three out of 4 hens treated with leptophos showed OPIDN. The concentration of leptophos decreased sharply in the blood, liver, brain and spinal cord from 24 to 48 hr after leptophos administration, but clearance of leptophos was relatively slow in the …

[Pharmacokinetics of the organophosphorous insecticide leptophos in the hen].
Yamaguchi Y. Yamaguchi Y. Nihon Eiseigaku Zasshi. 1989 Feb;43(6):1159-68. doi: 10.1265/jjh.43.1159. Nihon Eiseigaku Zasshi. 1989. PMID: 2473232 Japanese.
The decline patterns of leptophos in tissue were considerably different from each other. While leptophos concentrations in adipose tissue and sciatic nerves decreased mono-exponentially, leptophos in other tissues (liver, kidney, heart muscle, leg muscle, bra …

Ecotoxicology of phenylphosphonothioates.
Francis BM, Hansen LG, Fukuto TR, Lu PY, Metcalf RL. Francis BM, et al. Environ Health Perspect. 1980 Jun;36:187-95. doi: 10.1289/ehp.8036187. Environ Health Perspect. 1980. PMID: 6159210 Free PMC article.
The phenylphosphonothioate insecticides EPN and leptophos, and several analogs, were evaluated with respect to their delayed neurotoxic effects in hens and their environmental behavior in a terrestrial-aquatic model ecosystem. ...Desbromoleptophos, a contaminant and metabo …

Neurotoxicity of organophosphorus insecticides Leptophos and EPN.
El-Sebae AH, Soliman SA, Elamayem MA, Ahmed NS. El-Sebae AH, et al. J Environ Sci Health B. 1977;12(4):269-87. doi: 10.1080/03601237709372071. J Environ Sci Health B. 1977. PMID: 72768
Additional particular properties of both Leptophos and EPN were found in their ability to cause delayed neurotoxic ataxia in chickens and sheep fed once on sublethal doses of these compounds. It is believed that the phosphonate ester configuration of EPN and Leptophos …
