Method: Rats were randomly divided into five groups (n = 10). Sham: abdomen was opened, and closed. OVX: ovaries were removed. OVX + vardenafil, OVX + tadalafil, and OVX + udenafil groups: ovaries were removed and closed, and after 6 months from postoperative, 10 mg/kg of vardenafil, tadalafil, and udenafil were administrated as daily a single-dose for 60 days, respectively. Histopathologic and immunohistochemical examinations were performed for angiogenesis, and biochemical analysis for vascular endothelial growth-factor (VEGF), VitaminD(3), BMP2 and 4 levels in rat's kidney. Results: VEGF, BMP2 and 4, VitaminD(3), and angiogenesis were high in the all inhibitor groups compared with the sham and OVX (p < .05). However, BMP4 levels were only high in the OVX + tadalafil group (p < .05). Conclusion: The results indicated that vardenafil, udenafil, and especially tadalafil increased VEGF, BMP2, and VitaminD(3) levels.eninfo:eu-repo/semantics/closedAccessAngiogenesisPhosphodiesterase-5 InhibitorOvariectomyBone Morphogenetic ProteinVitamin DArticle1284Q2Q21121112732314927WOS:000527830700001
