Effects of Acitretin on Angiogenesis induced by Vascular Endothelial Growth Factor (VEGF) in Patients with Psoriasis / 中华皮肤科杂志

ABSTRACT

Objective To investigate the mechanism of effects of acitretin on the treatment of psoriasis. Methods The expression of vascular endothelial growth factor (VEGF) and micro-vascular density (MVD) were detected by immunohistochemical technique before and after treatment with acitretin in 32 patients with psoriasis. Serum level of VEGF was measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). Results The expression of VEGF protein and MVD were significantly higher in psoriatic lesions before treatment with acitretin than those after treatment (P
