Donepezil hydrochloride (donepezil: (+/-)-2-[(1-benzylpiperidin-4-yl)methyl]-5,6-dimethoxy-indan-1-one monohydrochloride) is a potent acetylcholinesterase inhibitor used for treatment of Alzheimer's disease. Although acetylcholinesterase inhibitors are used as a symptomatic treatment for Alzheimer's disease, it is not clear whether or not they are effective(More)
Intercollicular decerebration in animals induces sustained facilitation of muscle tone of the limbs and this animal model has been used to assess centrally acting muscle relaxants. We have examined the involvement of central and spinal cord serotonergic pathways in the onset of excessive muscle tone in an intercollicularly decerebrated rat. Descending(More)
Cerebral ischemia induces a massive efflux of glutamate causing delayed neuronal death in stroke-prone spontaneously hypertensive rats (SHRSP) but not in Wistar Kyoto rats (WKY). It is obvious that L-N-nitroarginine (L-NNA; NO synthase (NOS) inhibitor), benzamide (poly(ADP-ribose) synthetase inhibitor), and growth factors are involved in reducing neuronal(More)
The axolemma is considered a well-established mitogen, responsible for Schwann cell proliferation during Wallerian degeneration in the peripheral nerve. However, very little is known about the role of macrophages in Schwann cell proliferation. To test the possible influence of macrophages on Schwann cell proliferation during Wallerian degeneration,(More)
The effects of a new analgesic drug, ciramadol, on single neuronal activities of lamina V-type cells of the spinal dorsal horn were investigated in spinal rats when applied microelectrophoretically to the cells or administered systemically. In the majority of lamina V-type cells examined, ciramadol inhibited the activities induced by intra-arterial(More)
