56. Experimental Studies on Cerebral Swelling (II)

Morphological study on experimental cerebral vasospasm. II. Fluorescence microscopic examination on experimental cerebral vasospasm.

Basilar arteries with experimental vasospasm were studies histochemically using a catecholamine fluorescence technique in 15 cats. Fluorescence microscopy of normal vessels revealed abundant catecholamine fluorescence in the adventitia and in close contact with the media, but none within the media. Experimental subarachnoid hemorrhage resulted in depletion of catecholamine fluorescence in the a...

Ultrastructural studies on mitochondrial swelling.

Mitochondrial swelling induced by valinomycin, calcium chloride and P(i) was studied after potassium permanganate fixation in suspension. Valinomycin induces a rapid K(+) influx, increase of the matrix space and out-folding of the cristae, with good preservation of the matrix material. This swelling is reversible but the cristae do not completely re-form and have a blebbed appearance. On repeat...

Diffuse cerebral swelling.

By means of computerized tomography (CT) diffuse cerebral swelling has been shown to exist in the early stages of severe acute head injury. But, to our knowledge, it has not been intensively studied in blunt head trauma. The purpose of this study is to elucidate the clinical features, pathogenesis and outcome of the patients with diffuse cerebral swelling occurring in the case of blunt head tra...

Ii. Studies in Experimental Tetany

Experimental cerebral infarction. II. Clinicopathological model of deep cerebral infarction.

Experimental Cerebral Infarction. II. Clinicopathological Model of Deep Cerebral Infarction • Injection of silicone rubber cylinders into the internal carotid system permits selective occlusion of the proximal middle cerebral artery segment in the dog. Occlusions of this segment obstruct the mouths of the lenticulostriate arteries and result in deep cerebral hemisphere infarctions. Surface vess...
