[11C]-p- and m-octopamine hydrochloride were synthesized from [11C]HCN in a two-step sequence. Chemical and enzymatic approaches were used for the formation of the [11C]cyanohydrin intermediates as the key step. Isolated radiochemical yields of 0.7-2.3% at the end-of-synthesis were obtained with

Functions of octopamine in the mammalian brain are still not well known. An important aspect of this problem is the relationship between octopamines and catecholamines. Previous data have shown that their respective ontogenic evolutions are not parallel. Do the changes

A 71-year-old man was admitted because of treatment-resistant orthostatic hypotension of unknown aetiology. When aged 64 years he developed some impotence and later urinary incontinence and urinary frequency. At 68 years he noted vertigo on physical activity, and a year

Phenolamines, particularly octopamines, are of special importance in avoidance behavior. In the Roman low avoidance (RLA) strain, p-octopamine can induce locomotor behavioral activity that is normally observed in the Roman high avoidance (RHA) strain. For these reasons, the levels of
We investigated the effects of the calcium entry blocker nimodipine on cerebral autoregulation, BBB, and vasogenic edema in animal experiments. In the first series of rats, ICBF was measured with H2 clearance using a balanced multiwire surface electrode. Variations in
