[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
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
To study the acute effect of norfenefrine, given orally in aqueous solution, on the urethral closure function, profilometry was performed before and after administration of placebo and increasing doses of norfenefrine in 6 females with genuine stress incontinence. A weak

Administration of p-octopamine by intracerebroventricular (i.c.v.) or intrathecal (i.t.) routes, but not orally, produced antinociception in the acetylcholine-induced abdominal constriction test (ED50 = 24.8 and 3.6 micrograms, respectively). Likewise, i.c.v. and i.t., but not peripheral (up to 200 mg/kg s.c.)
