  • It is well known that soy isoflavones play beneficial roles in the prevention of chronic diseases such as breast cancer, cardiovascular disease and osteoporosis. However current data are not sufficient for estimating the level of isoflavone intake. To use the urinary isoflavone excretion as a maker of isoflavone intake,26 participants consumed the isoflavone extract capsule (90 mg soy isoplavones/capsule) daily for 3 months. The study compared effects of pre- and post-isoflavone supplement in the following parameters; physical examination, dietary recalls, and urinary isoflavon excretion. The average age, height and weight were 65.7 years, 149.4 cm, and 57.3 kg. Subjects maintained regular diet pattern, and average daily nutrient intakes between pre- and post- supplementation were not significantly different except vitamin A, carotene and vitamin C. There was no significant difference between pre- and post- supplementation in terms of daily isoflavone intake. The basal urinary isoflavone excretion was 8.37 mg/day (daidzein 6.23 mu genistein 2.14 mg), and average daily excretion rate was IS.8%. Urinary isoflavone excretion was significantly increased, after isoflavone supplementation for 3 months as compared the basal level (p<0.01). Our data suggest that urinary isoflavone level, especially daidzein and genistein, may be a useful maker to estimate isoflavone intake.

  • Bone cells produce multiple growth factors and cytokines that have effects on bone metabolism and can be incorporated into the bone matrix. The present study was designed to extend these observations by examining the interactions between transforming growth factor-$\beta$(TGF-$\beta$) or interleukin-$1\beta$(rhIL-$1\beta$) and bone cells in a rat long bone culture model. IL-$1\beta$ regulates several activities of the osteoblast cells derived from rat long bone explants in vitro. IL-$1\beta$ stimulated cellular proliferation as well as the synthesis of prostaglandin $E_2$ and Plasminogen activator activity in the cultured cells in a dose-dependent manner. TGF-$\beta$ is present in the bone matrix and potentially released during bone resorption. TGF-$\beta$ reduced basal bone resorption and inhibited vitamin $D_3[1,25(OH)_2D_3]$-induced bone resorption in rat long bone cells. These results support the role of IL-$1\beta$ in the pathological modulation of bone cell metabolism, with regard to implication in the Pathogenesis of osteoporosis by IL-$1\beta$, and that TGF-$\beta$ positively inhibits the bone resorption.

  • Excessive and hyperactive osteoclast activity causes bone diseases such as osteoporosis and periodontitis. Thus, the regulation of osteoclast differentiation has clinical implications. We recently reported that dehydrocostus lactone (DL) inhibits osteoclast differentiation by regulating a nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), but the underlying mechanism remains to be elucidated. Here we demonstrated that DL inhibits NFATc1 by regulating nuclear factor-κB (NF-κB), activator protein-1 (AP-1), and nuclear factor-erythroid 2-related factor 2 (Nrf2). DL attenuated IκBα phosphorylation and p65 nuclear translocation as well as decreased the expression of NF-κB target genes and c-Fos. It also inhibited c-Jun N-terminal kinase (JNK) but not p38 or extracellular signal-regulated kinase. The reporter assay revealed that DL inhibits NF-κB and AP-1 activation. In addition, DL reduced reactive oxygen species either by scavenging them or by activating Nrf2. The DL inhibition of NFATc1 expression and osteoclast differentiation was less effective in Nrf2-deficient cells. Collectively, these results suggest that DL regulates NFATc1 by inhibiting NF-κB and AP-1 via down-regulation of IκB kinase and JNK as well as by activating Nrf2, and thereby attenuates osteoclast differentiation.

  • The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.

  • The purpose of this study is to investigate the effects of indoor and outdoor exercise environments on bone mineral density and body composition in old women. A total of 26 old women were randomly divided into two groups: an indoor exercise group (IE, n=13) and an outdoor exercise group (OE, n=13). The exercise groups performed moderate exercise (HR max 50~70%; RPE 11-15) three times a week for 60 minutes over 20 weeks. After exercise training, bone mineral density was significantly improved in the OE group as compared with the IE group. Body fat mass was significantly decreased in the IE group. Weight, lean body mass, and body fat mass were significantly decreased in the OE group. Body mass index was significantly decreased in the outdoor exercise group as compared to the IE group. Our findings show that a 20-week program of outdoor exercise training improves bone mineral density and body composition in old women. As mentioned above, it has been found that engaging in an outdoor exercise program for 20 weeks has a positive effect on bone mineral density and body composition in old women. In conclusion, engaging in the outdoor exercise program, including aerobic and resistance exercises, for 20 weeks improved bone mineral density and inhibited bone loss in old women and had a positive influence on vitamin D levels, thereby potentially lowering the risk of osteoporosis.

  • Menopause is often associated with the incidence of several chronic diseases including osteoporosis, cardiovascular disease, and obesity. Hormone replacement therapy (HRT) is an effective regimen that has been found to prevent these diseases in postmenopausal women. However, HRT is accompanied by an increased risk of unfavorable outcomes. Therefore, this study was conducted to evaluate the effects of Ecklonia cava, a kind of seaweed, extract on bone turnover markers in symptomatic menopausal women. For this study, the following four groups of 9-week-old Sprague-Dawley rats were evaluated over 6 weeks: normal rats (SHAM), ovariectomized rats (OVX-CON) and ovariectomized rats that were treated with Ecklonia cava extracts. The optimum extraction temperature and solvent of Ecklonia cava were found to be $80^{\circ}C$ and 80% ethanol. We measured the osteocalcin and CTx content, enzyme ALP activity in serum and collagen content in the cartilage, bone, skin and lungs. We found that the levels of indicators of bone metabolism such as ALP, osteocalcin and CTx were lower in rats in the Ecklonia cava extract group than the OVX-CON group. In addition, the collagen contents in the bone, cartilage, skin and lungs decreased in response to ovariectomy, but the levels of collagen were greater in the bone of rats that were treated with Ecklonia cava extract than in the bone of rats in the OVX-CON group. According to these results, we were able to know the effects of Ecklonia cava extract on bone aging in ovariectomized rats. Consequently, we expect Ecklonia cava extract to have an effect on bone aging in postmenopausal women.

  • Osteoporosis is one of the major health problem affecting postmenopausal women. Estrogen deficiency results in an increase in bone turnover, lead to bone resorption and an increase risk of fracture. The aim of this study was to evaluate the effects of Platycodon grandiflorum A. extract (PG) in bone metabolism in ovariectomized estrogen-deficient rats. Two groups were surgically ovariectomized (OVX). The third group was sham operated. Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with PG at 50mg/kg body wt (OVX-PG50) The Platycodon grandiflorum extracts were orally administrated at 1mL per day. The ovariectomy caused a decreasing in the levels of collagen content in bone, cartilage and skin tissues. However PG group, supplementation with Platycodon grandiflorum extract, were increased the level of collagen content in bone, cartilage and skin tissues than OVX-control group. PG group had a higher content of pyridinoline in collagen than OVX-control group. Alkaline phosphatase activity on serum were decreased after supplemented with the PG extract. These results might be expected that Platycodon grandiflorum is believed to be possible protective effects in postmenopausal bone loss.

  • Glycogen storage disease type Ib (GSD Ib) is one of the rare inherited metabolic disease caused by mutation of SLC37A4 gene. Clinical characteristics include hepatomegaly, hypoglycemia, lactic acidosis, hyperlipidemia and high serum uric acid concentration. The authors analyzed clinical and molecular characteristics of three Korean patients (one male and two females) with GSD Ib by retrospective review of medical records. Two patients were diagnosed in toddler period by hypoglycemia and hepatomegaly. One patient was diagnosed by growth retardation and short stature in puberty. c.412T>C (p.Trp138Arg) (3/6 alleles, 50.0%) was most frequently observed, following by p.Leu348Valfs*53 (1 allele), p.Pro191Leu (1 allele), p.Ala148Val (1 allele) in molecular analysis. Uncooked corn starch and allopurinol was administered. Because all three patients had neutropenia and recurrent infections, G-CSF was administered. Two patients had severe osteoporosis needing calcium supplement. The patient who diagnosed at puberty had relatively poor prognosis demonstrated by having severe infection and complications in liver and kidney.

  • Background: As the population is aging, chronic diseases and depression are becoming the main problems in a country's healthcare system. In this study, we aimed to explore the associations between chronic diseases and depression among the elderly in South Korea. Methods: We analyzed 9,975 (men, 4,147; women, 5,828) respondents obtained from the 2014 National Survey of Living Conditions and Welfare Needs of Korean Older Persons. Our dependent variable was either 1 or 0 according to whether a respondent had depression or not, where depression was defined when the Short Form of Geriatric Depression Scale score was 8 or more points. Variables of interest were 24 types of chronic diseases and covariates included various socio-demographic and health behavior characteristics. We performed Rao-Scott chi-square tests and hierarchal logistic regression analyses by gender, reflecting the characteristics of the survey. Results: A significant difference was found in the proportion of having depression between genders (men 18.9% vs. women 23.4%). According to fully adjusted, multivariable analyses, for elderly men, relative to those without any chronic disease, the odds ratio of depression was 1.56 (95% confidence interval [CI], 1.10-2.22) in the stroke patients group and 1.82 (95% CI, 1.01-3.25) in the osteoporosis patients group. For elderly women, the odds ratio was 1.96 (95% CI, 1.28-3.00) in the fracture/dislocation and aftereffects patients group and 1.30 (95% CI, 1.03-1.64) in the group of patients with other diseases. Conclusion: Even after being adjusted for diverse characteristics, some chronic diseases were significantly associated with depression in the elderly and the association differed between genders. Therefore, public health and medical interventions are needed to manage such chronic diseases together with curing depression symptoms.
