Hydration of single or mixed phospholipids or lipid protein mixtures at low ionic strength results in the formation of a population of large, solvent free, single bilayer vesicles with included volumes of up to 300 microliters/mumol lipid. Their size ranges from 0.1 to 300 microns and they can be sorted out according to size by centrifugation. When formed(More)
RATIONALE Nitric oxide (NO) is implicated in the acute locomotor activating effects of some addictive drugs such as amphetamine, caffeine, and PCP, but has not been investigated in the case of toluene. OBJECTIVES This study determined the contribution of the NO-cyclic GMP (cGMP) pathway to locomotor stimulant effects of toluene. METHODS Locomotor(More)
RATIONALE Toluene exposure during brain growth spurt has been shown to elevate the seizure susceptibility induced by N-methyl-D: -aspartate (NMDA). In the present study, behavioral responses to NMDA antagonists were studied to determine whether neonatal toluene exposure produces residual deficits in the NMDA glutamatergic system controlling behaviors. We(More)
Toluene has been reported to antagonize the function of N-methyl-D-aspartate (NMDA) receptors. In this study, the effects of neonatal toluene exposure on NMDA receptors in primarily cultured cerebellar granule neurons were examined. Sprague-Dawley rats were treated with toluene (0, 200, 500, and 1000 mg/kg, i.p.) from postnatal day (PN) 4 to PN 7. Under(More)
Toluene, an industrial organic solvent, is voluntarily inhaled as drug of abuse. Toluene has been shown to inhibit the nicotinic acetylcholine receptors. Nicotinic receptors play an important role in brain development during brain growth spurt and early adolescence. The long-term effects of neonatal and adolescent toluene exposure on behavioral responses to(More)
