BACKGROUND
Polycystic ovary syndrome(PCOS) is characterized by the presence of chronic anovulation and hyperandrogenism, The prevalence of PCOS in premenopausal women of about 5~ 10%. There may be significant ethnic and racial variations in the prevalence and clinical presentation of PCOS. The current study was undertaken to determine the prevalence of PCOS and to identify the clinical characteristics of PCOS in Korea. METHODS: From March 2003 to March 2004, medical students from Ewha Womans University were investigated for the prevalence of PCOS. The evaluation included a history and physical examination, a modified Ferriman-Gallwey hirsutism score and screening for hyperandrogenemia. PCOS was diagnosed by the presence of the following: 1) oligomenorrhea, 2) hyperandrogenemia and/or hirsutism(a modified Ferriman-Gallwey score> or =6), and 3) the exclusion of related disorders. Hyperandrogenemia was defined as a free testosterone level above the 95th percentile of that for normal cycling nonhirsute women. RESULTS: Out of 492 students, 386 replied to the questionnaire and 203 students(19~31 yr of age) participated in the physical examination and blood sampling. Eumenorrhea without hirsutism was present in 133 students(65.5%), oligomenorrhea was present in 39 students(19.2%), hyperandrogenism was present in 21 students(10.3%) and hirsutism was present in 3(1.5%) of the 203 women. The prevalence of PCOS was 4.9%(10 of 203 students), and only 2 of 10 women with PCOS were hirsute. The mean body mass index of students with PCOS was 22.7+/- 4.3kg/m2, and two women was obese. The plasma insulin levels during the 75g oral glucose tolerance test in women with PCOS was significantly higher when compared to the age and body mass index of the controls. CONCLUSION: The prevalence of PCOS was 4.9% in college students from Seoul. This rate is similar to those rates reported by other investigators in Greece(6.7%) and United States(4%). Obesity and hirsutism are not common in Korean women with PCOS. We are planning to survey a more diverse age groups to determine the prevalence of PCOS

BACKGROUND
To evaluate the effects of alendronate in preventing bone loss at the spine and hip in Korean cases of primary osteoporosis, we treated 138 patients with 10 mg of alendronate daily. Of the 138 patients treated, 50 were treated for one complete year, and at their final visit, measurements were taken to assess the completed outcome of the reatment, and the results from this small group were compared with those of the rest. The way this has been written causes ambiguity concerning exactly who was being studied. Check that my rewrite of this section conveys correctly the group that was studied, and how. METHODS: The serum levels of calcium(Ca) and phosphorous(P), total alkaline phosphatase(ALP), the urine calcium creatinine ratio(Uca/cr) and urine deoxypyridinoline(DPD) were measured before, during, and after the 1 year treatment period. The bone mineral densities(BMDs) at the spine and hip were also measured before and after the treatment period. New clinical fractures and side effects, were evaluated during the treatment period. RESULTS: The total serum ALP and urine DPD were decreased significantly, after the treatment period, by 38.3 and 40.5% respectively. The bone mineral density at the spine and hip were significantly increased after 1 year, by 6.7 and 2.0%, respectively. Of the 50 subjects who had completed a full year of treatment, only 4(8%) had developed new clinical fractures. Of the 138 patients who had been treated, 8(5.8%) discontinued the medication due to side effects. Of these, 7 had gastrointestinal symptoms, and 1 had skin eruption. CONCLUSION: Alendronate significantly decreased the total serum ALP and urine DPD and significantly increased spine and hip bone mineral density. Alendronate 10mg was effective in preventing bone loss in Korean cases of primary osteoporosis.

AbstractAbstract PDF
BACKGROUND
The glucose uptake rate is the limiting step in glucose utilization and storage. The failure of insulin to stimulate glucose uptake in muscle appears to be a primary defect of insulin resistance. This study was undertaken to examine the effect of physiological hyperinsulinemia on the phosphorylation of the insulin receptor (IR-beta), insulin receptor substrate (IRS), Akt kinase and GSK-3 in isolated skeletal muscle, in people with type 2 diabetes (n=9) and control subjects (n=11). METHODS: 75g OGTT and euglycemic hyperinsulinemic clamp test were done. And vastus lateralis muscle was obtained before and 30 min into the euglycemic clamp. Western blots were performed for tyrosine phosphorylation of insulin receptor substrate (IRS) and phosphorylation of the insulin receptor(IR-beta), Akt and GSK-3. RESULT: There were no statistical differences in the mean age, BMI and body fat between the control subjects and diabetic patients. The fasting blood sugar and HbA1c in controls and diabetic patients were 98.+/-1.3 and 208.1+/-16.5 ng/dl, and 5.4+/-0.5 and 9.2+/-0.6%, and 1.4+/-0.2 in the control subjects, and 72.2+/-52.3% (p<0.01) and 10.2+/-6.3 (p<0.01) in the diabetic patients, respectively. The insulin resistance from the euglycemic hyperinsulinemic clamp tests were 8.2+/-0.6 mg/kg/min and 3.7+/-1.1 ng/kg/min in the control subjects and in the diabetic patients, respectively (p<0.01). Compared with the normal controls, insulin-stimulated IR phosphorylation was no different to that in the diabetic patients. However, insulin-stimulated IRS phosphorylation, insulin-stimulated Akt phosphorylation and insulin-stimulated GSK-3 phosphorylation were reduced in the diabetic patients compared with the normal controls by 24, 43 and 25%, respectively (p<0.05). CONCLUSION: In korean type 2 diabetic patients, the insulin resistance may be due to the impairment of the upstream insulin signal molecular network. Further studies will focus on determining whether these signaling defects are the cause of the development of insulin resistance, or secondary to the altered metabolic state, associated with type 2 diabetes mellitus

AbstractAbstract PDF
BACKGROUND
Dehydroepiandrosterone (DHEA) is an androgen precursor, and is known to be decreased by the aging process. DHEA has been known to have a protective effect on insulin resistance and cardiovascular disease in men, but remains controversial in women. The aim of this study was to elucidate the role of DHEA on insulin resistance, and the risk for cardiovascular disease, in women. METHODS: We analyzed the relationship between DHEA sulfate (DHEAS), known to have a longer half-life and less diurnal variation than DHEA, and insulin resistance syndrome (IRS) in 471 non-diabetic women from an urban community diabetes prevalence study. Serum DHEAS concentrations were measured using a commercially available radioimmunoassay kit. RESULTS: 1. The frequencies of obesity, impaired glucose tolerance, hypertension and dyslipidemia were 25.3, 8.5, 21.9 and 6.2%, respectively, and the frequency of IRS was 16.5%. 2. DHEAS was significantly inversely correlated with age (r=-0.47, p<0.001), systolic blood pressure (r=-0.18, p<0.001), diastolic blood pressure (r=-0.10, p<0.05), fasting serum glucose (r=-0.10, p<0.05), postchallenge 2 hour glucose (r=-0.12, p<0.01) and triglycerides (r=-0.16, p<0.01). 3. As serum DHEAS concentrations, by quartiles, were decreased, the age-adjusted frequency of hypertension was significantly increased (p<0.05). 4. A Multiple linear regression analysis revealed that DHEAS was significantly associated with age (p<0.0001) and BMI (p<0.05). 5. A Logistic regression analysis showed that DHEAS was not associated with IRS after adjustment for age. CONCLUSION: DHEAS is inversely associated with age. DHEAS has no harmful effect, and may even have a protective role, on insulin resistance syndrome. Prospective examinations of DHEAS and insulin resistance syndrome in women are needed to confirm the mechanism for the association between DHEAS and the development of cardiovascular disease.
