ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of Sanlengwan (SLW) on adhesion molecules expression and the accretion in ectopic endometrium of rats.</p><p><b>METHOD</b>Endometriosis was established by surgical implant of endometrial tissue which belong to its body. Forty EMS model rats were randomly divided into five groups: model control group, three dose of SLW groups and anastrozole group. Meanwhile, eight normal rats were used as the normal group. All the rats were treated for 4 weeks respectively, and the volume of grafts were measured by vernier caliper, morphological changes were measured by HE stain, and the adhesion molecules, ICAM-1 and CD44 protein, were also measured by immunohistochemical test before and after treatment of SLW.</p><p><b>RESULT</b>SLW markedly reduced the volume of grafts, improve the morphological characters and decreased the expression of ICAM-1 and CD44 in ectopic endometrial tissue.</p><p><b>CONCLUSION</b>SLW can inhibit the accretion of ectopic endometrium tissue of rats, and its mechanism might be associated with inhibiting the expression of ICAM-1 and CD44 protein.</p>
