• Inbred strains ofWistar rats that spontaneously develop high blood pressure are used commonly as models of essential hypertension. In two of these strains, the spontaneously hypertensive rat and the genetically hypertensive rat, there is evidence for peripheral neurotrophic abnormalities. In the spontaneously hypertensive rat, there is elevated production of nerve growth factor, but the numbe...

We retrospectively assessed the diagnostic value of cerebral arteriography for the search of an etiology in 102 patients with nontraumatic intracerebral hemorrhages evaluated between 1980 and 1985. Arteriography was diagnostic in 22 of 50 non-hypertensive patients and in only 6 of 47 hypertensive patients. Five patients with a bleeding diathesis had normal arteriography. From the total group, w...

The common carotid arteries of normotensive non-arteriosclerotic Sprague-Dawley (S-D) rats, mildly hypertensive but arteriosclerotic breeder S-D rats, severely hypertensive but non-arteriosclerotic virgin spontaneously hypertensive rats (SHR), and severely hypertensive breeder SHR were ligated to induce injury. Three weeks post-ligation, the animals were killed and histopathological sections of...
