Stroke-Prone Spontaneously Hypertensive Rats
Background and Purpose We examined metabolic and functional changes when forebrain ischemia was induced in strokeprone spontaneously hypertensive rats by bilateral carotid artery occlusion. In addition, the protective effect of clentiazem was evaluated in this model. Methods Rats were anesthetized with urethane. Cerebral blood flow was measured with a laser Doppler fkrwmeter. Cerebral high-ener...
متن کاملCerebral plasminogen activator activity in spontaneously hypertensive stroke-prone rats.
BACKGROUND AND PURPOSE In the spontaneously hypertensive stroke-prone rat, it is unclear whether plasminogen activator plays a role in the development of stroke. The present study was undertaken to investigate brain levels of plasminogen activator activity in spontaneously hypertensive stroke-prone rats and Wistar-Kyoto rats. METHODS Plasminogen activator was purified from the brains of rats ...
متن کاملPlatelet survival studies in stroke-prone spontaneously hypertensive rats (SHRSP).
Platelet survival was studied by using 51Cr-labeled platelets in stroke-prone spontaneously hypertensive rats (SHRSP), stroke-resistant SHR (SHRSR) and normotensive control rats of the Wistar-Kyoto (WK) strain. Relatively young animals of the same age prior to the development of cerebrovascular lesions (cerebral infarction and/or hemorrhage) were used. Platelet half-life time in SHRSP was sligh...
متن کاملInhibition of NOS enhances pulmonary vascular changes in stroke-prone spontaneously hypertensive rats.
To determine the effects of chronic nitric oxide (NO) blockade on the pulmonary vasculature, 58-day-old spontaneously hypertensive rats of the stroke-prone substrain (SHRSP) and Wistar-Kyoto rats (WKY) received N(omega)-nitro-L-arginine (L-NNA; 15 mg. kg(-1). day(-1) orally for 8 days). Relaxation to acetylcholine (ACh) in hilar pulmonary arteries (PAs), the ratio of right ventricular (RV) to b...
متن کاملVascular permeability precedes spontaneous intracerebral hemorrhage in stroke-prone spontaneously hypertensive rats.
BACKGROUND AND PURPOSE Stroke-prone spontaneous hypertensive rats (SHRsp) fed a high-salt diet develop malignant hypertension, blood-brain barrier breakdown, and spontaneous intracerebral hemorrhage (ICH). The precise spatial and temporal relationship between these events has not been well-delineated. METHODS Ten SHRsp male rats, fed a high-salt diet, were imaged weekly using MRI, starting at...
