13. Excessive sweating: an uncommon sign of basilar artery occlusion.
Excessive sweating of the face and, to a lesser degree, of the thorax and limbs, occurred after basilar artery occlusion in a 15 year old Saudi boy. Magnetic resonance imaging (MRI) showed a limited bilateral paramedian infarction of the rostral ventral pons. Basilar artery occlusion in children and adolescents is a rarity. Excessive sweating following such

14. Role of protein kinase C in constrictor responses of the rat basilar artery in vivo.
1. The goal of this study was to determine the effects of activation and inhibition of protein kinase C on the rat basilar artery in vivo. 2. The diameter of the basilar artery was measured through a craniotomy in rats anaesthetized with pentobarbitone sodium (50 mg kg-1, I.P., supplemented with 20 mg kg-1 h-1). Diameters were measured under control conditio

15. Basilar artery aneurysm and Anderson-Fabry disease.
A case of basilar artery aneurysm is described. The patient had a family history of similar aneurysms and also of a rare spingolipidosis, Anderson-Fabry disease.

16. Recombinant tissue plasminogen activator in two patients with basilar artery occlusion.
Two patients with angiographically proved basilar artery occlusion were treated with systemic recombinant tissue plasminogen activator (rtPA) according to protocol. The first patient was in a locked-in state and gradually deteriorated. On repeat angiography the basilar artery remained occluded. He died and necropsy revealed a pontine haemorrhagic infarction.

17. Vertebro-basilar ischaemia with thrombosis of the vertebral artery: report of two cases with embolism.
Two cases with vertebro-basilar infarcts associated with severe stenosis of the vertebral artery in its cervical part is reported. Complete thrombosis of the vertebral artery was observed after a short delay in both cases. As the carotid arteries were normal and the controlateral vertebral artery was dominant, an embolic mechanism was suspected. No new event

18. Giant cell arteritis with spinal cord infarction and basilar artery thrombosis.
A patient with active giant cell arteritis developed paraparesis and dissociated sensory loss due to infarction in the anterior spinal artery territory at the level of T12. Three days later fatal basilar artery thrombosis occurred. No occlusive lesion was found to explain the anterior spinal artery syndrome but this was associated with active arteritis. Alte

19. Responses of isolated human basilar arteries to 5-hydroxytryptamine, noradrenaline, serum, platelets, and erythrocytes.
The isolated human basilar artery suspended in Kreb's solution contracts to 5-hydroxy-tryptamine, noradrenaline, and histamine, which stimulate specific receptors. Normal human serum contains an unidentified contractile substance, and erythrocytes relax the artery. Serum and erythrocytes potentiate 5-HT contractions. This preparation is suitable for studying

20. Noradrenaline receptors on the rat basilar artery.
1. Intracellular recordings were obtained from the arterial smooth muscle cells of rat basilar artery during perivascular nerve stimulation and during the application of adrenoceptor agonists and antagonists. 2. Perivascular nerve stimulation evoked excitatory junction potentials. Increased stimulation resulted in action potentials which were associated with

21. Transluminal angioplasty for arteriosclerotic disease of the distal vertebral and basilar arteries.
OBJECTIVE: Percutaneous transluminal angioplasty (PTA) for the distal vertebral and basilar artery is now being performed in selected patients with haemodynamically significant lesions of the posterior cerebral circulation. Its effect and overall results were examined. PATIENTS AND METHODS: A balloon dilatation catheter specifically developed for these proce

22. Calcium channel antagonism by pizotifen.
Pizotifen is a clinically effective anti-migraine agent with potent anti-serotonin and anti-histamine properties. Pizotifen is equipotent in blocking contractions of the canine basilar artery induced by serotonin, norepinephrine or calcium chloride. As a result, the primary action of pizotifen in the canine basilar artery system appears to be calcium channel

23. Thrombolytic treatment for acute occlusion of the basilar artery.
Sixteen patients with acute occlusion of the basilar artery were treated with systemic fibrinolysis. Recanalisation was achieved in 10 patients; five patients survived and 11 patients died. Survival was associated with vascular recanalisation in every case. Most of the survivors were younger than 50. An age above 50 and a comatose state on admission seem to
