Aim: Alendronate enhances bone morphogenetic proteins (BMP)-mediated osteoblast differentiation. A balanced regulation of inhibitors of DNA binding/differentiation (Ids) plays an important role in BMP-induced osteoblast differentiation. However, there are no studies on the possible roles of Id genes in alendronate-induced osteoblast differentiation. This study investigated the effect of alendronate on the expression of Id genes in osteoblast differentiation. ...

Introduction: This study aims to assess 25-hydroxyvitamin D—25(OH)D—status in perimenopausal women to analyze its relationships with serum PTH levels and bone mineral density (BMD).Methods: A total of 102 individuals who visited to climacteric clinic in Sanggye paik hospital participated in the study. Serum 25(OH)D and intact parathyroid hormone (PTH) were measured. BMD was determined by dual x-ray absorptiometry (DXA) at lumbar spine, femoral ...

Objectives: To find the predicting factors for bone density in premenopausal women.Methods: Two hundred and forty-five premenopausal women without factors that can cause secondary osteoporosis were analyzed. Age, height, weight, change of height from peak height, history (Hx) of fracture, family Hx of hip or other fracture, Hx of estrogen use, calcium or vitamin D supplementation, smoking and previous Hx of amenorrhea more than 3 months were questioned. ...

Objectives: To evaluate the effect of hormone therapy on the change of bone mineral density in women who showed early menopause after pelvic radiation therapy for uterine cervical cancer.Materials and methods: Through retrospective chart review, the changes of bone mineral density in 63 women with early menopause after pelvic radiation therapy for uterine cervical cancer were evaluated. After the diagnosis of early menopause which was defined as level of...

Objective: Bone is one of endocrine organ and osteocytes secretes FGF23, Sclerostin and DKK1. FGF23 inhibits renal phosphate reabsorption and suppresses 1-α hydroxylase activity. Calcitriol stimulates FGF23 synthesis in bone. We aimed to determine the effect of single bolus injection of vitamin D on serum FGF23, DKK1 and Sclerostin concentrations in vitamin D-deficient subjects.Design and methods: The study group was composed of placebo group with s...

Introduction: The significance of sarcopenia and low muscle mass are especially emphasized in these days. Sarcopenia is well known to highly correlate with fragility and increases the risk of falling in the elderly and an important risk factor for disability and mortality. Evidence of inter-relaionship of muscle with bone metabolism is increasing. Therefore we investigated the relationship between BMD and muscle mass among healthy Korean premenopausal women.<p class="abste...
