Platelets in the subarachnoid space
Autor: D. J. Boullin, G. H. DuBoulay, J. T. Hughes, V. Aitken
Publikováno v: Acta Neurochirurgica. 89:64-70
In nine baboons following intracisternal injection of a suspension of their own washed platelets, biphasic spasm was demonstrated by vertebral angiography. Constriction of the intra-arachnoid portion of the vertebral artery and the basilar artery was

Simplified determination of serotonin in plasma by liquid chromatography with electrochemical detection
Autor: P C Tagari, D J Boullin, C L Davies
Publikováno v: Clinical Chemistry. 30:131-135
This simplified determination of serotonin in human plasma involves "high-performance" liquid chromatography with electrochemical detection. Deproteinated samples of platelet-poor plasma are injected directly into the chromatograph without preliminar

Human Blood Platelets Accumulate Radioactivity from the Dipeptides 14C-glycylglycine and 14C-glycylproline
Autor: Christine E Heading, D. J. Boullin
Publikováno v: Thrombosis and Haemostasis. 31:142-148
SummaryHuman blood platelets were suspended in plasma or Krebs solution and incubated with radiolabeled glycylglycine or glycylproline in order to study cellular uptake. Platelets accumulated radioactivity against a concentration gradient. In the cas

The calibre of cerebral arteries of the rat studied by carotid angiography: A model system for studying the aetiology of human cerebral arterial constriction after aneurysmal rupture
Autor: Victoria Aitken, G. H. du Boulay, D J Boullin, P. Tagari
Publikováno v: Neuroradiology. 21:245-252
Rupture of human cerebral arterial aneurysms is followed by prolonged cerebral arterial constriction; there is evidence that cerebrospinal fluid (CSF) from such patients contains vasoconstrictor substances which may cause the arterial constriction. T

Responses of human and baboon arteries to prostaglandin endoperoxides and biologically generated and synthetic prostacyclin: their relevance to cerebral arterial spasm in man
Autor: S Moncada, D J Boullin, W P Blaso, S Bunting, T M Hunt
Publikováno v: British Journal of Clinical Pharmacology. 7:139-147
1 Isolated strips of human or baboon basilar, middle cerebral, vertebral or common carotid arteries were set up in an isolated organ bath or in a superfusion cascade system. 2 These arteries relaxed to prostacyclin but contracted to prostaglandin end

Evidence for the presence of a vasoactive substance (possibly involved in the aetiology of cerebral arterial spasm) in cerebrospinal fluid from patients with subarachnoid haemorrhage
Autor: D. G. Grahame-Smith, D J Boullin, J. Mohan
Publikováno v: Journal of Neurology, Neurosurgery & Psychiatry. 39:756-766
Cerebrospinal fluid from patients with subarachnoid haemorrhage and cerebral arterial spasm contracted the isolated basilar artery and potentiated contractions produced by 5-hydroxytryptamine, noradrenaline, and six prostaglandins. The unidentified s

Single and repeated administration of neuroleptic drugs to rats: Effects on striatal dopamine-sensitive adenylate cyclase and locomotor activity produced by tranylcypromine and L-tryptophan or L-dopa
Autor: D. G. Grahame-Smith, D. J. Boullin, A.R. Green, D.J. Heal
Publikováno v: Psychopharmacology. 49:287-300
Injection of tranylcypromine and L-tryptophan results in rats displaying behavioural changes including hyperactivity, probably due to stimulation of post-synaptic 5-hydroxytryptamine (5-HT) receptors. Increased locomotor activity of a different type

Relationship between presence of vasoconstrictor activity in cerebrospinal fluid and time after subarachnoid haemorrhage from rupture of cerebral arterial aneurysms
Autor: G. H. Du Boulay, D J Boullin, D M Forster, T M Hunt, W P Blaso
Publikováno v: Journal of Neurology, Neurosurgery & Psychiatry. 42:625-634
The relationship between clinical condition and vasoconstrictor factors in cerebrospinal fluid was studied in 19 patients for up to six weeks after subarachnoid haemorrhage. Vasoconstrictor activity was assayed biologically. Sixteen of 19 patients im
