Inhibition of Angiotensin-Converting Enzyme Reduces Cerebral Infarction Size in Experimental-Induced Focal Cerebral Ischemia in the Rat

Background: The role of Renin Angiotensin System (RAS) in ischemic/reperfusion (I/R) injuries is not fully elucidated. Furthermore, it is not clear whether inhibition of RAS by Angiotensin-Converting Enzyme (ACE) inhibitors has beneficial effects in terms of protecting the brain from I/R injuries. In this study enalapril is used as an ACE inhibitor to evaluate the role of RAS in I/R injuries in...

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...

In vivo antiplatelet aggregatory activity of Aloe vera juice on mice cerebral micro vessels

Aloe vera plant (A. vulgari and A. barbadensis) has being used traditionally as a medicinal plant for centuries. Gel from the inner central zone of the leaves and latex from pericyclic cells are used for medicinal purposes. The present study was conducted to elucidate the beneficial effects of Aloe vera juice on the platelet aggregation in cerebral microvessels of mice. Male mice were injected ...
