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: Diabetes mellitus is a heterogeneous group of disorders characterized by high serum glucose levels and by disturbances of carbohydrate and lipid metabolism. There are many cutaneous signs of this common endocrinopathy, such as nercobiosis lipoidica diabeticorum, diabetic bullosis, shin spot, diabetic pruritus, etc. OBJECTIVE: In this study, we investigated whether extracellular matrix gene expression in cultured skin fibroblast is influenced by insulin and Insulin-like growth factor-I(IGF-I). METHOD: Total RNA was isolated from insulin or IGF-I treated human skin fibroblasts. The Northern blot and slot-blot hybridization were then conducted. RESULTS: The mRNA levels of pro α1(I) collagen, pro α1(I11) collagen, fibronectin in insulin and IGF-I treated normal skin fibroblasts increased compared with untreated normal skin fibroblasts. CONCLUSION: Our results show that insulin and IGF-I stimulate collagen formation in normal skin fibroblast at physiological concentrations. Therefore, these demonstrate that insulin can modulate the expression of extracellular matrix gene.

For many years permanent soft denture liners has been widely used in dental practice directly or indirectly because of its function in absorbing and distributing the impact force. However, it reveals problems such as lack of permanency and decreased bond strength in long term use. The purpose of this study is to measure the bond strength and failure between denture base resin and several permanent liners. Lucitone 199 was used as denture base resin with soft acrylic liners (Triad, Tokuso Rebase) and silicone elastomers (Tokuyama, Ufi Gel C) bonded to measure the tensile strength before and after thermocycling. The thermocycling was done in 2000 cycles at 5degrees C, 26degrees C and 55degrees C and the measured tensile strength values before and after thermocycling were compared. The mode of failure was investigated in the separated specimens. The results are as follows. 1. As to tensile strength, the strongest material is Tokuso Rebase followed by Triad, Tokuyama, Ufi Gel C in before thermocycling and the order of Triad, Tokuso Rebase, Tokuyama, Ufi Gel C in after thermocycling state. There was significant difference between the values of Triad, Tokuso Rebase and Tokuyama, Ufi Gel C(p<0.05). 2. As to degree of displacement, Ufi Gel C showed most displacement with or without thermocycling treatment and also the difference was significant with the other materials(p<0.05). 3. As to comparisons before and after thermocycling, Tokuso Rebase and Tokuyama showed significant difference in bond strength, whereas Triad and Tokuso Rebase showed significant difference in the degree of displacement(p<0.05). 4. In debonded specimens, Triad and Ufi Gel C showed adhesion failure and Tokuyama showed cohesion failure. Both failures were observed in Tokuso Rebase with adhesion failure up to 70%. The results of this study showed that degree of bond strength between permanent soft denture liner and denture base resin were variable. There was a significant difference between soft acrylics and silicone elastomers with regard to bond strength. Further research in improving bond strength of widely used silicone elastomers and in developing the method of measuring bond strength between denture base resin and the lining materials is needed.
