Expression Of Endocan And Vascular Endothelial Growth Factor In Recurrent Minor Aphthous Ulcers, Enji Ahmed Mahmoud, Wesam Abdelmonem, Olfat Gamil Shaker, Dalia Mohey-Eldien Ghalwash

Dentistry

Background: Recurrent aphthous ulcers (RAU) are common painful inflammatory lesions of the mucous lining of the mouth. Endocan, previously identified as endothelial cell specific molecule-1, is implicated as a vital player in the regulation of several inflammatory processes. A number of inflammatory cytokines and pro-angiogenic growth factors including VEGF upregulate endothelial cells synthesis and expression of endocan. Material and Methods: Clinical scores of pain and ulcer size as well as level of endocan and VEGF were determined in swaps from aphthous ulcer and contra lateral normal mucosa in 30 patients (nine males and twenty one females) with age ranging from …
