[Expression of bcl-2 in the normal endometrium and endometrium of adenomyosis].
Using immunohistochemical ABC staining, we detected the expression and role of bcl-2 in normal endometrium(n = 17) and eutopic and ectopic endometrium with adenomyosis(n = 16) during the menstrual cycle. The first result was that the expressions of bcl-2 in the eutopic endometrium were the same as the normal endometrium, showing predominantly in the glandular epithelial cells, and obviously cyclic changes throughout the menstrual cycle. This result suggests that these changes may be regulated by ovarian hormone and play an important role in the proliferation and physiologic death of normal endometrial glandular epithelial cells to regulate the menstrual cycle. Bcl-2 expression in the glandular cells of ectopic endometrium of adenomyosis had no cyclic change and bcl-2 staining had remained in the whole menstrual cycle. The second result suggests that the above mentioned phenomena may play an important role in the pathogenesis of adenomyosis.
