In the final experiment, the adenosine A 2A antagonist MSX-3 significantly attenuated the tremulous jaw movements induced by the 3.0 mg/kg dose of galantamine, which is consistent with the hypothesis that co-administration of adenosine A 2A antagonists may be beneficial in reducing parkinsonian motor impairments induced by anticholinesterase treatment.", In two additional studies, analyses of freeze-frame video and electromyographic activity recorded from the lateral temporalis muscle indicated that the local frequency of these galantamine-induced jaw movements occurs in the 3-7 Hz frequency range that is characteristic of parkinsonian tremor. In a second study, co-administration of the muscarinic antagonist scopolamine (0.0156-0.25 mg/kg I.P.) produced a dose dependent suppression of tremulous jaw movements induced by a 3.0 mg/kg dose of galantamine, indicating that galantamine induces these tremulous oral movements through actions on muscarinic acetylcholine receptors. The first experiment demonstrated that systemic injections of galantamine (0.75-6.0 mg/kg I.P.) induced a dose-related increase in tremulous jaw movements in rats. The present studies were conducted to determine if galantamine induces tremulous jaw movements, a rodent model of parkinsonian tremor, and to investigate whether these oral motor impairments can be reversed by co-administration of adenosine A 2A antagonists. Although these drugs improve cognitive symptoms, they also can induce or exacerbate parkinsonian symptoms, including tremor. In the final experiment, the adenosine A 2A antagonist MSX-3 significantly attenuated the tremulous jaw movements induced by the 3.0 mg/kg dose of galantamine, which is consistent with the hypothesis that co-administration of adenosine A 2A antagonists may be beneficial in reducing parkinsonian motor impairments induced by anticholinesterase treatment.Ībstract = "Anticholinesterases are the most common treatment for Alzheimer's disease, and, in recent years, a new group of cholinesterase inhibitors (i.e. Parenting style and child outcome research (baumrind: authoritarian- restrictive parenting, insist on obedience, rigid rules.Anticholinesterases are the most common treatment for Alzheimer's disease, and, in recent years, a new group of cholinesterase inhibitors (i.e. Mothers are more avoidant and inconsistent with a lack of sensitivity to infant"s needs: some cultural variations with attachment.
