Since then, many observations of patient populations both hospital and community based, with controls, have confirmed the finding. A meta-analysis on selected studies showed the relationship to

ABT — 418, a Novel Nicotinic Agonistities selective for subtypes of nAChRs can be developed which are potentially free of the side effect liabilities associated with (-)-nicotine. Recent data also suggests that neuronal nAChR function can be enhanced at sites distinct from where (-)-nicotine interacts on the a subunit. nAChR agonists

Synaptosomes prepared from mouse brain tissue are loaded with .Rb. ions and then stimulated with nicotine. When the nAchR is activated by nicotine, the io

All neurons tested were activated by three nicotinic agonists with the following rank order: DMPP > Nicotine> ACh. With 100 .M each of these agonists, the peak responses ranged from 100 pA to 4 nA at a membrane potential of —60 mV. The n
