Sep corticali e midollari nel ratto dopo trauma spinale
No full textUn gruppo di 10 ratte e' stato sottoposto a trauma spinale per compressione epidurale secondo il metodo di Tator. Dopo 4 mesi dal trauma sono stati registrati i SEP corticali e midollari, sopra e sottolesionali, ed e' stato esaminato il midollo leso tramite microscopia elettronica. E' stata evidenziata una maggiore sensibilita' dei SEP midollari rispetto a quelli corticali nel valutare il danno funzionale. Inoltre, e' stata riscontrata una maggiore correlazione dei SEP midollari con i dati clinici ed anatomo-patologic

Intra-extracranial thrombosis of the internal carotid artery associated with meningioma
No full textCases of internal carotid artery occlusion associated with an intracranial tumor are rare. The authors report two cases of complete occlusion of the internal carotid artery. In one case the thrombosis was probably caused by direct compression of the carotid siphon by a large meningioma arising from the inner third of the sphenoid wing. In the other it was associated with multiple meningiomatosis although there was no contiguity between the intracranial tumors and the occluded carotid artery. After a review of literature we think they are of some interest, and we have found an interesting incidence of association between thrombosis and meningiomaCases of internal carotid artery occlusion associated with an intracranial tumor are rare.

Chronic damage after spinal trauma in rat: neurophysiological and ultrastructural investigations.
No full textA group of 10 rats underwent spinal trauma by epidural spinal compression according to Tator's procedure. After 4 months from injury cortical and spinal SEP were recorded, and the spinal injured tract was examined by electronic microscope. We studied morphologic and functional changes showed after some months behind the trauma. This report demonstrates and compares the varying sensitivity of cortical and spinal SEP for revealing functional spinal damage; ultrastructural investigations testify to the existence of reparative processes of the nervous tissue
