To estimate the delayed neurotoxic effect of OPs on the next generation, we tried two examinations; one was on the distribution of leptophos in tissues and eggs of hens which are highly susceptible to the delayed neurotoxic effect of OPs
F Y Piao et al.
The Journal of toxicological sciences, 20(5), 609-617 (1995-11-01)
Delayed neurotoxicity induced by leptophos, an organophosphorus insecticide, was intensified in hens when phenylmethylsulfonyl fluoride (PMSF) at dose of 30, 60, and 120 mg/kg body weight was administered at different time intervals (24 hr, 3 days, and 5 days) for

Journal of toxicology and environmental health, 23(2), 217-228 (1988-01-01)
The effects of multiple doses of desbromoleptophos, fenitrothion, and pure fenthion on brain acetylcholinesterase (AChE), brain neurotoxic esterase (NTE), and walking were investigated in immature chicks, below the age of sensitivity to organophosphorus ester-induced delayed neurotoxicity (OPIDN). Ten milligrams per

Changes in acetylcholinesterase (AChE) levels in the brain and various segments of the spinal cord of birds fed subchronic repeated oral doses of 0-(4-bromo-2,5 dichlorophenyl) 0-methyl phenylphosphonothioate, (leptophos, 15 mg/kg/day) is reported. The effect of leptophos on the histological structure
