Cordon ombilical. Nouvelles sur l’acétylcholine
2005
Introduction L’acetylcholine (Ach) fut la premiere substance impliquee dans la transmission synaptique. Elle est synthetisee a partir de l’enzyme acetyl-choline transferase (ChAT) et est degradee par l’acetyl-choline esterase (AchE). Il existe des anticorps specifiques diriges contre la ChAT et l’AchE qui ont permis de mettre en evidence la distribution de ce neurotransmetteur au niveau des systemes nerveux central et peripherique. Il faut rappeler que les neurones somato-moteurs, pre-ganglionnaires du tronc cerebral et de la moelle epiniere, les neurones post-ganglionnaires visceraux des ganglions parasympathiques et de quelques ganglions orthosympathiques sont cholinergiques. Ces donnees …
Kinking, coiling, and tortuosity of extracranial internal carotid artery: is it the effect of a metaplasia?
2006
INTRODUCTION: Morphological anomalies of the extracranial internal carotid artery (ICA) cause symptomatic cerebrovascular insufficiency in 4-16% of the cases. The aim of the present study is to evaluate macroscopic and microscopic features of a group of extracranial ICA anomalies, specifically kinking, coiling, and tortuosity, eventually affecting the surgical approach. MATERIALS AND METHODS: From January 2003 to December 2005, 10 out of 169 (6%) revascularized patients (pts) were operated upon because of an ICA anomaly. They were all but two symptomatics. Seven pts were treated by ICA transection and end-to-side reimplantation of the ICA at the level of the carotid bulb; three pts were tre…
