ABSTRACT
AIM:Damaging of Endothelial cells and adhesion of leukocytes and platelets were studied in rat mesentery microvessels after ischemia-reperfusion.METHODS:The model was made by losing blood and reperfusion from carotid artery in rat. Changes in mesentery microvessels were observed by high magnify microscope.RESULTS:
Leukocyte and platelet adhesions were found in venules and co-capillaries 1-3 hours after ischemia-reperfusion. Endothelial cells were edema and vascular walls were thickening. Vacuoles formed in intracytoplasm of some vascular endothelium and some bigger endothelial vacuoles prominenced toward the luminal surface. Vacuoles had the shape of circle and the diameter was 10-30 μm. More vacuoles were found in arterioles, even there were several vacuoles in a arteriole. The biggest vacuole almost occupied 2/3 of vascular lumen.CONCLUSION:Edema and vacuole formation in vascular endothelium showed endothelial cells were damaged seriously after ischemia-reperfusion.
