Leukocyte-endothelial interactions in pial arterioles and venules on development of cerebral ischemia in rats.

Abstract

In vivo microscopy was used to study the interaction between leukocytes and the pial venular and arteriolar endothelium in rats during cerebral ischemia evoked by bilateral ligation occlusion of the carotid arteries. Specimens were obtained from 40 arterioles and 30 venules (diameter up to 40 micron) of the pia mater from Wistar rats (n = 7) subjected to ischemia for 5 h to respiratory arrest. The experimental data demonstrated significant differences in changes in the adhesion of leukocytes to the endothelium of arterial and venous microvessels during the development of hypoxia.
