Objectives: To prevent future osteoporosis, it is important to identify factors that affect bone health in adolescents as well as adults. This study aimed to examine the relationship between lipid profiles and insulin resistance and BMC in Korean adolescent population.Methods: Data from 706 boys and 621 girls who participated in the Korea National Health and Nutrition Examination Survey from 2008 to 2011 were analyzed. Lipid profiles were measured, and h...

Many reports have proposed significant role of vitamin D on immune mediated disease. This study analyzed lymphocyte subsets according to serum 25(OH) vitamin D levels in postmenopausal women to determine the potential effect of vitamin D on immune-mediated disease.On a prospective observational basis, we enrolled 31 postmenopausal women who underwent health checkup in our hospital. Peripheral blood drawn for the estimation of total T, B cell, NK cell cou...

We have reported femoral osteopenia in short term-vitamin D restricted rats without deterioration in tibial cortical bone volume (CBV), geometry or strength1. This study aimed to establish the effect of extended vitamin D deficiency in aged rat tibial volume and strength. Female Sprague-Dawley rats (9 m, n=6/group) were fed a diet containing varying vitamin D3 (D) levels (0, 2, 12, and 20 IU/day) with either low (0.1%, LCa) or high (1%, HCa) diet...

The purpose of this study was to investigate the effects of fitness program with vitamin D supplementation for biochemistry related to vitamin D, muscle mass and physical functions in elderly women.The subjects were elderly women aged 65 or older, regularly visiting a senior welfare center and a senior citizen center in city. A total of 65 subjects were divided into experimental group (n=34) and control group (n=31). The intervention fo...

Background: There have been many studies on the association between vitamin D and testosterone in the world. But it has not been fully clarified. Furthermore, data in Korean men is limited. This study aimed to determine the association between vitamin D and testosterone levels in korean men.Methods: This cross sectional study analyzed serum 25-hydroxyvitamin D (25(OH)D) and total testosterone in 365 Korean men over 25 years of age who visited a local uni...

The aim of this study was to evaluate the adsorption of salivary proteins on giomer (Beautifil II) and composite resin (Filtek Z350).Three discs (5 mm diameter and 1 mm height) were prepared for each material. Three discs were immersed in 1 ml? of human saliva within polyethylene tube and stored at room temperature. Evaluations were performed by Bradford method and SDS gel electrophoresis for analysis of salivary protein adsorbed on giomer and composite ...

Human skeletal dysplasias consist of over 450 distinct conditions that affect the development and maintenance of bone and cartilage. Broadly they can be characterized by those that affect primarily bone, i.e., the osteodysplasias, vs those that affect cartilage, i.e., the chondrodysplasia. However, the lines dividing these two are increasingly blurred as we recognized them to be a spectrum of osteochondrodysplasias. Importantly, the advent of next generation sequencing has led...

Introduction: To compare serum vitamin D levels in elderly patients with or without osteoporotic spinal compression fractures (OSCF) and to evaluate a correlation between serum vitamin D level and several variables such as age, and bone mineral density (BMD), bone turnover markers.Methods: The medical records of 78 patients with OSCF (fracture group) and 84 age-matched control patients who were diagnosed osteoporosis without OSCF (control group) were rev...

Purpose: The purpose of the present study was to characterize the extent of sarcopenia among orthopaedic surgery patients.Methods: This retrospective cross-sectional study identified 222 patients immediately after or before an orthopaedic surgery including elective total hip and knee arthroplasty and hip fracture surgery at a single institution. 364 patients from an outpatient department who did not have an orthopaedic surgery were also examined as a con...

Aging is associated with a loss of systemic bone mass and an increased risk of especially the spine and hip. Therefore bone loss of teeth and ridge resorption can occur in the mouth. However, results of several studies investing association between systemic bone density and oral health have varied. In this study, we investigated the relationship between osteoporosis and dental caries with the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2008&#1...
