N-Methyl-D-aspartate (NMDA) antagonists reduce ischemic brain damage and associated hypermotility. Two potent, selective and competitive NMDA antagonists, cis-4-(phosphonomethyl)-2-piperidine-carboxylic acid (CGS 19755) and 4-(3-phosphonopropyl)-2-piperazine-carboxylic acid (CPP), were characterized in the gerbil ischemia model with respect to dose-response(More)
Apomorphine HCl (Apo) (0.25, 0.5 or 0.75 mg sc), a dopamine (DA) receptor agonist, induced penile erections (PEs) (monitored by mercury strain gauges and continuous recording on paper strip charts) in 7 out of 9 normal subjects and placebo in 1 of these 9 (p less than 0.05). Apo-induced PEs recurred in each of the 6 subjects retested. Benztropine (2 mg iv)(More)
BACKGROUND A phase II trial of alternating i.v. and oral vinorelbine in combination with cisplatin was designed to determine the response rate, safety profile, progression-free survival, overall survival and quality of life (QoL) in advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Fifty-six chemotherapy-naïve patients received cisplatin(More)
Sulpiride (100 mg IM), an atypical neuroleptic, which does not block dopamine (DA) receptors that are linked to adenylate cyclase, abolished the growth hormone (GH) response to the DA receptor agonist, apomorphine (Apo) HCl (0.5 mg SC) in seven healthy male subjects. These results suggest that Apo increases GH secretion in man by an effect on DA receptors(More)
All our advanced, severe cases of Alzheimer's disease have dramatic cholinergic cell losses in the nucleus basalis of Meynert even after correction for cell or nucleoli shrinkage. There is a good correlation between choline acetyltransferase activity and "healthy" cell number in the nucleus basalis of Meynert. Half of the Alzheimer disease cases have(More)
Multiple neurotransmitter systems are affected in senile dementia of the Alzheimer's type (SDAT). Among them, acetylcholine has been most studied. It is now well accepted that the activity of the enzyme, choline acetyltransferase (ChAT) is much decreased in various brain regions including the frontal and temporal cortices, hippocampus and nucleus basalis of(More)
All our advanced severe cases of Alzheimer's disease had dramatic cholinergic cell loss in the basal forebrain, even after correction for cell or nucleolus shrinkage. We examined the relation between cell loss in the various subdivisions of the nucleus basalis of Meynert and plaque counts in corresponding and noncorresponding projection areas. This relation(More)
CCK-33 (225 Ivy Dog Units iv) antagonized the growth hormone response to the dopamine receptor agonist, apomorphine HCl (0.5 mg sc), and increased basal prolactin secretion in normal male volunteers. A stress mediated prolactin effect could not be excluded. CCK-8 (5 ug iv) antagonized the growth hormone response to apomorphine but had no effect on basal(More)
