[Quantitative variation in lysosomes in the epithelium of the human uterine tube in the menstrual cycle and after the menopause]

Abstract

Quantitative variation of the lysosomes in the epithelium of the human uterine tube in the menstrual cycle and in post-menopausal period. The authors counted the lysosomes in the human uterine tube in the menstrual cycle and in post-menopausal period. The post-menopausal women were separated in two groups: one received oral estrogens during twenty one day and the other did not. Fragments of uterine ampullae were removed, fixed and submitted to Gomori acid phosphatase method. Results show that the number of lysosomes during the proliferative phase was significantly greater than in secretory phase and post-menopausal period. The number of lysosomes in post-menopausal period was significantly greater in women treated with estrogens. Our result show that estrogens are responsible for the increase of the number of lysosomes.
