Histological and immunohistochemical aspects of cerebral vessels of the elderly.

The central nervous system is considered the most complex morphological structure of the human body. Between nervous tissue and cerebral circulation is a very close relationship, so transient vascular meningocerebral disturbances cause changes in neuronal function clinically expressed as various neurological signs and symptoms, especially in the elderly. In this study, we examined from the histological and immunohistochemical point of view encephalon fragments collected from 24 patients aged between 46 and 85 years.

Clinical and morphological correlations in acute ischemic stroke.

We studied the clinical and histopathological changes in twenty-seven cases of acute ischemic stroke, aged between 65 and 75 years. All deaths occurred within 30 days after stroke. The aim of our study was to establish the clinical and histological correlations in acute ischemic stroke to detect prognostic factors.
