PURPOSE: Osteoporosis is generally regarded as disease of women and there are extensive data about post-menopausal osteopotosis, but there is relatively little information concerning the osteoporosis in aging male. We aimed to determine the relationships between age ,androgen and bone mineral density (BMD) in elderly korean men. MATERIALS AND METHODS: We evaluated the sex hormones and BMD of 82 elderly men between May 1999 and April 2000. Serum free testosterone (FT), total testosterone (TT), DHT, LH, FSH and Prolactin were measured by RIA. BMD at anteroposterior L2-4, femoral neck, ward's triangle, femoral trochanter and femoral shaft were determined by dual-energy X-ray absorptiometry. We defined group I as free testosterone <10ng/dl and group II as 10ng/dl. RESULTS: Serum LH and FSH increased with age. There was a significant decrease in serum FT with age, but T concentrations remained unchanged. There were significant declines with age in BMD at femoral neck, Ward's triangle, femoral trochanter, femoral shaft. Serum FT were significantly correlated to BMD at anteroposterior L2-4, femoral neck, Ward's triangle, femoral trochanter, femoral shaft. After controlling for age, serum FT were significantly correlated to BMD at femoral trochanter, femoral shaft. Mean BMD was significantly lower in group I than group II at anteroposterior L2-4, femoral shaft. CONCLUSIONS: We suggest that FT is a male osteoporotic marker in man older than 50 years and bone mineral density should be considered for diagnosis of male osteoporosis associated with PADAM, especially when FT is lower than 10ng/dl.

BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.
