Abstract

Twenty nine cases of oral hemangiomas composed of capillary hemangioma, cavernous hemangioma and pyogenic granuloma were examined with lectin histochemistry using ulex europaeus agglutinin I, ricinus communis agglutinin I, wheat germ agglutinin, concanavalin A, dolichos biflorus agglutinin, soybean agglutinin and peanut agglutinin, and immunohistochemistry using anti von Willebrand factor antibody in order to understand the nature of each endothelial cell. The following results were obtained; 1. UEA-I that specifically bound alpha-L-fucose was observed mainly in the endothelial cells of capillary hemangioma and hemangioma of granulation tissue type. 2. RCA-I which had specific affinity to beta-D-galactose was so identified in all endothelial cells of all type hemangiomas and normal blood vessels that it was supposed to be a useful marker of the cells. 3. WGA with specific affinity to N-acetyl-glucosamine was also found in various endothelial cells. 4. Con A which had specific affinity to alpha-D-mannose was not observed in various endothelial cells. 5. DBA, SBA and PNA that were specific bound up with N-acetyl-galactosamine were seen in the normal micro-vessels, especially in subepithelial regions. 6. Immunohistochemically, von...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
