Objective: To study the effects and mechanism of Guizhi Fuling Wan on inhibiting angiogenesis in a rat model of endometriosis. Method: Rat endometriosis model was induced by autologous transplantation. The rats with endometriosis were divided into control group (negative control)
low dose Guizhi Fuling Wan group (4.13 g·kg-1)
high-dose Guizhi Fuling Wan group (8.26 g·kg-1) and gestrinone group (positive control
0.23 g·kg-1). There was also a sham-operated group. After treatment for 28 days
the rats were killed by cervical dislocation. The expression of prolifarating cell nuclear antigen(PCNA) and CD31 in ectopic endometrium was assessed by immunohistochemistry. The level of vascular endothelial growth factor(VEGF) in peritoneal fluid (PF) was determined by ELISA. The mRNA expression of VEGF and hypoxia inducible fuctor-1 HIF-1α in ectopic endometrium was evaluated by real-time PCR. Result: After treatment
Guizhi Fuling Wan could suppresse the expression of PCNA and CD31 in ectopic endometrium
decline concentration of VEGF in PF (P<0.05)
and reduce mRNA expression of VEGF and HIF-1α in ectopic endometrium (P<0.01). Conclusion: Guizhi Fuling Wan significantly suppress angiogenesis in a rat endometriosis model
and the mechanism may be related to the inhibition expression of VEGF and HIF-1α.
