Experimental phenylketonuria was induced in male rats by daily injections of alpha-methylphenylalanine and phenylalanine on postnatal Days 3-31. Beginning at 8 weeks of age, the animals were subjected to a test of observational learning followed by a test of latent learning (two tests of "advantageous" learning). The animals subjected to the PKU treatment(More)
Anxiolytics specifically increase the number of exploratory transitions in a two-chambered model system for anxiety in mice. Characterization of parameters to optimize and standardize this model required analysis of multiple use of test animals, intertrial interval, and circadian variability. Time of day did not affect exploratory activity in mice treated(More)
Cholecystokinin coexists with dopamine in mesolimbic neurons in mammalian brain. When injected directly into the nucleus accumbens, cholecystokinin (CCK) potentiated dopamine (DA)-induced hyperlocomotion and apomorphine-induced stereotypy. These effects were not mimicked by nonsulfated CCK, but were blocked by proglumide, a putative CCK antagonist, as well(More)
The nucleus accumbens contains many neuropeptides whose functions are presently unknown. The purpose of this study was to determine the extent to which these neuropeptides act in conjunction with the mesolimbic dopamine system. Microinjections of cholecystokinin, neurotensin, met-enkephalin, somatostatin, bombesin, as well as glutamate and muscimol, were(More)
OBJECTIVE To determine whether parent health behavior changes and feeding practices were associated with child changes in body mass index z-score and related health behaviors over the course of 1 year.  METHODS  Anthropometric data from 590 child-parent dyads of ethnic/racial minority groups were collected at baseline, 14 weeks (postintervention), and(More)
Fominoben, a centrally acting antitussive, has been shown recently to bind to the brain benzodiazepine binding site and to antagonize pentylenetetrazol-induced seizures. The present study reports the ability of fominoben to produce anti-anxiety effects analogous to diazepam in a mouse exploratory model for anxiolytics. This action of fominoben was blocked(More)
