Title of work: Angiogenesis in the border zones of cerebral ischemia The aims of work: The aim of this diploma thesis was to determinate the parameter of the angiogenesis after focal brain ischemia induced by photothrombosis in P7 rat pups. This thesis should answer the question, if there is some difference in vascular density according to the distance from the lesion and if there is some diference between the vascular density in normal brain and the brain with the lesion. Materials and Methods: Cerebral ischemia was induced in P7 rat pups with photothombic method. Intravenous administration of bengal rose dye was followed by illumination of beam of green laser over the cortex for 5 minutes at 0,5s on/off cycles. Bengal rose dye is potent photosensitive substance and the ilumination resulted in agregation of trombocytes and thrombosis. Cerebral ischemia evolved due to the thrombosis. After two months, the animals were overdosed with urethane and transcardially perfused. Then thein brain were cryoprotected and then cut into 50µm slices and prepaired for histological staining. The stained slices were the investigated under mikroskope. The microvessels in the cortex were counted and the density was estimated by stereological method. Results: Two brain with ischemic lesion and two control brain were...
