Hen brain microsomal preparation has phenyl valerate-hydrolyzing activity associated with neurotoxic esterase activity. Part of that activity is due to paraoxon-insensitive esterases and a sub-part of this is sensitive to neurotoxic organophosphates, i.e., mipafox and leptophosoxon. This neurotoxic agent sensitive

Recent investigation into a possible association between exposure to Leptophos and neurological symptoms in insecticide factory workers makes study of the neurological effects of Leptophos in the experimental situation particularly important. The present study utilizes a single oral dose of

In comparing neurotoxic esterase (NTE) inhibition properties of a series of phenylphosphonates, it was discovered that certain compounds including leptophos inhibited mipafox-insensitive phenylvalerate hydrolases. This leads to erroneous values for NTE inhibition which can be corrected by a differential assay:

The toxic and teratogenic effects of 4 organophosphorus compounds (phenyl saliginen cyclic phosphate (PSCP), leptophos-oxon (LPTO), tri-o-tolyl phosphate (TOTP), and paraoxon (PXN] were investigated in the embryos of 3 species of frogs. Developmental abnormalities were observed in surviving embryos of

Five organophosphorous insecticides: Leptophos, EPN, Cyanofenphos, trichloronate and salithion proved to cause irreversible ataxia not only to chicken but also to mice and sheep. TOCP was included as a reference. Cyanofenphos blocked the catecholamine B-receptor binding activity with 3H-norepinephrine at
