the natural cytotoxicity of cells prepared from the blood of human neonates and women at the time of parturition was investigated, using a 4 hr 51Cr release assay and two established cell lines as targets. Although cord cells proved to be cytotoxic, the overall level was distinctly lower than that of normal adult cells. Whereas adult cells from males gave(More)
This study reports the activity of neurotoxic esterase (NTE) and acetylcholinesterase (AChE) in the blood and central nervous system (CNS) of swine 6, 12, 24 and 48 h after a single oral dose of 800 mg tri-o-cresyl phosphate (TOCP)/kg. At all evaluated intervals, inhibition of NTE activity in leukocytes and the CNS was 88% or higher, with only slight(More)
We report the clinical signs and the effects on leukocyte neurotoxic esterase and red blood cell and plasma acetylcholinesterase (AChE) activities in swine orally administered a single dose of tri-o-cresyl phosphate (TOCP) at 400, 800 or 1000 mg/kg. Swine in all dosage groups exhibited signs consistent with inhibition of nervous tissue cholinesterase 3-48 h(More)

Given my own experiences with similar issues as a researcher, reviewer, and editor, and my(More)
