In an acute neurotoxicity study (MRID [number]), groups of (fasted), (age) (strain) (species) (#/sex) were given a single oral dose of (chemical name (% a.i.) in (name of vehicle) at doses of x, x, or x mg/kg bw and observed for (#) days. Neurobehavioral assessment (functional observation battery and motor activity testing) was performed in [number] animals/sex/group [at what time points]. [If applicable] Cholinesterase activity was determined by the [?] method in X rats/sex/dose in plasma and erythrocytes [at what time points], and in [# of regions or whole] brain [at what time points]. At study termination, [how many?] animals/sex/group were euthanized and perfused [in situ] for neuropathological examination. Of the perfused animals, [how many from which groups?] were subjected to histopathological evaluation of brain and peripheral nervous system tissues.
[any additional measures should be included in procedures section above]
Discuss findings at low, mid- and high doses. Include only major treatment related clinical signs, body weight or brain weight changes or gross and histopathology or neuropathology, including onset and/or duration if any, or the following statement: There were no treatment related effects on mortality, clinical signs, body weight, brain weight or gross and histologic pathology or neuropathology. FOB testing revealed no treatment-related effects. Note if there was a NOAEL for acute neurotoxicity (for Acute reference dose consideration during subsequent risk assessment.)
Based on the effects seen in this study, the LOAEL was [xxx (based on xxx]), with a NOAEL of [xxx].
The LOAEL for plasma cholinesterase inhibition was [xxx], with a NOAEL of [xxx].
The LOAEL for erythrocyte cholinesterase inhibition was [xxx], with a NOAEL of [xxx].
The LOAEL for brain cholinesterase inhibition was [xxx], with a NOAEL of [xxx].
