BACKGROUND AND PURPOSE We have previously reported that galantamine, a weak acetylcholinesterase inhibitor, improves prepulse inhibition (PPI) deficits in mice reared in social isolation. ACh receptors are involved in the underlying mechanism of PPI, but whether rearing in social isolation causes dysfunction of the cholinergic system is unknown. In this(More)
We have found that galantamine, but not donepezil, reversed isolation rearing-induced deficits of prepulse inhibition (PPI) via an activation of muscarinic M1 receptors. To explain this difference, the present study examined the effects of these acetylcholinesterase inhibitors on muscarinic receptor-mediated responses in in vitro and in vivo systems. Ca(2+)(More)
Galantamine, a drug for the treatment of Alzheimer’s disease, has neuroprotection in several experimental models and stimulates adult neurogenesis in the rodent brain, but the exact mechanism remains unclear. This study examined whether galantamine affects the expression of neurotrophic/growth factors in the mouse hippocampus and prefrontal cortex.(More)
We investigated expression of the Na(+)-L-carnitine cotransport system and its role in transport of tetraethylammonium in a kidney epithelial cell line, LLC-PK(1). L-Carnitine uptake in the LLC-PK(1) cells was markedly stimulated in the presence of Na(+). The uptake was saturable, with Michaelis constant and maximal uptake velocity values of 7.8 microM and(More)
Four unconjugated metabolites, which were produced through the oxidation of the isopropyl chain of 2-isopropylnaphthalene (2-IPN), were isolated from the urine of rabbits receiving 2-IPN orally and identified: 2-(2-naphthyl)propionic acid, 2-(2-naphthyl)-2-propanol, 2-(2-naphthyl)-1,2-propanediol, and 2-(2-naphthyl)-2-hydroxypropionic acid, together with a(More)
