N/A Objective : The goal of this study was to determine the relationship between peak bone density and polymorphism of estrogen receptor gene in Korean premenopausal women. Method : We amplified Estrogen receptor by polymerase chain reaction and its digestion pattern of Pvu II and Xba I was examined from the 172 women who were in premenopause. The genetic subtype was classified by its digestion pattern and its combination genotype, e.g. PP, Pp, pp, XX, Xx, xx, PPXX, PPXx, PPxx, PpXx, Ppxx, xxpp. Bone mineral density of each genetic subtype were compared. Results : The genotype distribution was as follows: PP; 16.3%, Pp; 45.9%, pp; 37.8%, XX; 1.2%, Xx; 25.0%, xx; 73.8%, PPXX; 1.1%, PPXx; 8.7%, PPxx; 6.4%, PpXx; 16.3%, Ppxx; 29.7%, ppxx; 37.8%. ER gene polymorphism was associated with bone mineral density at forearm bone mineral density (p<0.05) with the xx genotype having the less BMD than Xx genotype. Conclusion : Xba I estrogen receptor gene polymorphism is associated with bone mineral density in premenopausal women. Estrogen receptor gene polymorphism may have a modulatory role in bone metabolism in premenopausal women. And it can be used as predictor of forearm peak bone density.

N/A Objective : To determine the frequency and degree on change in mammographic densities, and calcification in the breast tissue, during different types of hormone replacement therapy and to evaluate the factors that play a role on the breast cancer. Method : A retrospective review of 268 cases menopausal women for HRT group and 52 cases menopausal women for unmatched control group. Mammographic evaluations for the distribution of breast densities and calcification, new solid mass and cyst in four different type of HRT were performed each every year during 5 years. The significant increase of breast densities and calcifications and new formation of neoplasm were taken with breast sonogram. 10 cases were biopsied for the confirmation of maliganancy. Result : Compared with the conrol groups, the hormone user group have a significant increase in the breast densitiy for 5 years (p<0.05), and the addition of progesterone in HRT showed a significant increase in the breast densities during 5 years (p<0.05), but we cannot find the correlation for new formation of solid mass and cyst and HRT (p>0.05). Among 10 cases in suspicious malignancy, 9 cases were confirmed to the malignancy by biopsy. Conclusion : The results of this study revealed that not only progesterone combined HRT but also estrogen only HRT significantly increased mammographic density. There is no relationship on the calcification and HRT in this study. The annual checking of mammography is necessary to HRT.
