To investigate predictable ultrasonographic findings of early abortion. To investigate objective rules for the screening of abortion Ultrasonographic examination of 111 early pregnancies between the sixth and ninth week in women who had regular 28 day menstrual cycles was performed. Ultrasonographic measurements of the gestational sac. Crown rump length and fetal heart rate were performed using a linear array real time transducer with doppler ultrasonogram. All measurements of 17 early abortions were compared to those of 94 normal pregnancies. Most of early aborted pregnanices were classified correctly by disciminant analysis with G-SAC and CRL (GSAC=0.5 CRL+15. Sensitivity 76.5%, specificity 96.8%). With the addition of FHR, 94.1 of early abortions could be predicted. In conclusion, ultrasonographic findings of early intrauterine growth retardation. Small gestational sac and bradycardia can be predictable signs suggestive of poor prognosis of early pregnancies.

PURPOSE: The purpose of this study was to identify effects of an obesity control program including rhythmical dance exercise, on body composition, knowledge about obesity, life habits and self-esteem among obese elementary school children. This program included obesity related health education and counseling based on behavior modification once a week, 1 hour-rhythmical dance class once a week and 40-minute jump rope classes twice a week for 8 weeks. METHOD: There were 29 students with obesity in the experimental and 28 in the control group. Participated was voluntary. The data were collected from April 16 to July 6 2007. chi-square-test, Fisher's exact test, paired t-test and t-test were used to analyze the data. RESULTS: Students in the experimental group showed significantly lower fat mass (t=-2.16, p=.036) and percent body fat (t=-2.93, p=.005) and significantly higher muscle mass (t=2.05, p=.045) and lean body mass (t=2.71, p=.009) than those in the control group. Knowledge of obesity increased significantly and eating habits changed significantly. But difference in exercise habits and self-esteem were not significant. CONCLUSION: This study provides evidence that an 8 week-obesity control program including rhythmical dance exercise is effective in decreasing body fat, increasing muscle mass and increasing knowledge of obesity in children who are obese.

Early fetal growth delay and early oligohydramnios have been suspected as signs of embryonal jeopardy. However, little information is available for the prediction of early abortion. Sonographic examination of 111 early pregnancies between the sixth and ninth gestational week with regular, 28 day menstrual cycles was performed to investigate predictable sonographic findings of early abortion. Sonographic measurements of the gestational sac (G-SAC), crown-rump length (CRL) and fetal heart rate (FHR) were performed using a linear array real time transducer with Doppler. All measurements of 17 early abortions were compared to those of 94 normal pregnancies to investigate the objective rules for the screening of early abortion. Most of the early aborted pregnancies were classified correctly by discriminant analysis with G-SAC and CRL (G-SAC = 0.5222 CRL + 14.6673 = 0.5 CRL + 15, sensitivity 76.5% specificity 96.8%). With the addition of FHR, 94.1% of early abortions could be predicted. In conclusion, sonographic findings of early intrauterine growth retardation, early oligohydromnios and bradycardia can be predictable signs for the poor prognosis of early pregnancies.

OBJECTIVE: The favored method of preserving fertility in young female cancer survivors is cryopreservation and autotransplantation of ovarian tissue. Reducing hypoxia until angiogenesis takes place is essential for the survival of transplanted ovarian tissue. The aim of this study was to investigate the role of angiopoietin-1 (Angpt-1), angiopoietin-2 (Angpt-2), and vascular endothelial growth factor (VEGF) in ovarian tissue grafts that were cryopreserved using two methods. METHODS: Ovarian tissues harvested from ICR mice were divided into three groups: group I (control), no cryopreservation; group II, vitrification in EFS (ethylene-glycol, ficoll, and sucrose solution)-40; and group III, slow freezing in dimethyl sulfoxide. We extracted mRNA for VEGF, Angpt-1, and Angpt-2 from ovarian tissue 1 week following cryopreservation and again 2 weeks after autotransplantation. We used reverse transcriptase-polymerase chain reaction to quantify the levels of VEGF, Angpt-1, and Angpt-2 in the tissue. RESULTS: Angpt-1 and Angpt-2 expression decreased after cryopreservation in groups II and III. After autotransplantation, Angpt-1 and Angpt-2 expression in ovarian tissue showed different trends. Angpt-1 expression in groups II and III was lower than in group I, but Angpt-2 in groups II and III showed no significant difference from group I. The vitrified ovarian tissues had higher expression of VEGF and Angpt-2 than the slowfrozen ovarian tissues, but the difference was not statistically significant. CONCLUSION: Our results indicate that Angpt-2 may play an important role in ovarian tissue transplantation after cryopreservation although further studies are needed to understand its exact function.

OBJECTIVE: Vitamin D-binding protein (VDBP) mediates various biological processes in humans. The goal of this study was to investigate whether VDBP gene polymorphisms could predispose Korean women to endometriosis. METHODS: We prospectively enrolled women with endometriosis (n = 16) and healthy controls (n = 16). Total serum 25-hydroxyl vitamin D (25(OH)D) concentrations were measured using an Elecsys vitamin D total kit. Levels of bioavailable and free 25(OH)D were calculated. Concentrations of VDBP were measured using a vitamin D BP Quantikine ELISA kit. DNA was extracted using a DNeasy blood & tissue kit. Two single-nucleotide polymorphisms (SNPs; rs4588 and rs7041) in GC, the gene that codes for VDBP, were analyzed using a TaqMan SNP genotyping assay kit. The functional variant of VDBP was determined based on the results of the two SNPs. RESULTS: Gravidity and parity were significantly lower in the endometriosis patients than in the control group, but serum CA-125 levels and the erythrocyte sedimentation rate were significantly higher. Total serum 25(OH)D levels in the endometriosis patients were significantly lower than in the control group. However, serum bioavailable 25(OH)D, free 25(OH)D, and VDBP levels did not differ significantly between the endometriosis and control groups. The genotypes and allele frequencies of GC were similar in both groups. CONCLUSION: Korean women with endometriosis had lower total serum 25(OH)D concentrations than controls. Neither serum VDBP concentrations nor polymorphisms in the gene coding for VDBP were associated with endometriosis. Further studies are needed to investigate the pathophysiology and clinical implications of 25(OH)D and VDBP in endometriosis.

OBJECTIVE: To investigate serum 25-hydroxyl vitamin D (25(OH)D) and vitamin D-binding protein (VDBP) concentrations in women with endometriosis according to the severity of disease. METHODS: Women with mild endometriosis (n = 9) and advanced endometriosis (n = 7), as well as healthy controls (n = 16), were enrolled in this observational study. Serum total 25(OH)D concentrations were analyzed using the Elecsys vitamin D total kit with the Cobas e602 module. Concentrations of bioavailable and free 25(OH)D were calculated. Concentrations of VDBP were measured using the Human Vitamin D BP Quantikine ELISA kit. Variables were tested for normality and homoscedasticity using the Shapiro-Wilk test and Leven F test, respectively. Correlation analysis was used to identify the variables related to total 25(OH)D and VDBP levels. To assess the effects of total 25(OH)D and VDBP levels in the three groups, multivariate generalized additive modeling (GAM) was performed. RESULTS: Gravidity and parity were significantly different across the three groups. Erythrocyte sedimentation rate (ESR) and CA-125 levels increased as a function of endometriosis severity, respectively (p= 0.051, p= 0.004). The correlation analysis showed that total 25(OH)D levels were positively correlated with gravidity (r = 0.59, p< 0.001) and parity (r = 0.51, p< 0.003). Multivariate GAM showed no significant relationship of total 25(OH)D levels with EMT severity after adjusting for gravidity and ESR. However, the coefficient of total 25(OH)D levels with gravidity was significant (1.87; 95% confidence interval, 0.12–3.63; p= 0.040). CONCLUSION: These results indicate that vitamin D and VDBP levels were not associated with the severity of endometriosis.

Objective:
The purpose of this study was to investigate the status of bone health in women working in agriculture and analyze the associations between bone health and various vitamin D-related biomarkers.
Methods:
This observational study enrolled women working in agriculture (n = 210) and control occupations (n = 180). The concentration of serum total 25-hydroxy vitamin D [25(OH)D] was measured using the Elecsys Vitamin D Total Kit, and serum vitamin D-binding protein (VDBP) was measured by enzyme-linked immunosorbent assay (ELISA). Along with albumin, 25(OH)D and VDBP were used to calculate the concentrations of bioavailable and free 25(OH)D. Bone mineral density (BMD) and T-score were measured at lumbar 1–4 and the femur neck using dual-energy X-ray absorptiometry. To identify factors affecting BMD, log-linear model and linear regression analysis were performed for statistical analysis.
Results:
Agricultural women workers showed higher serum concentrations of bioavailable 25(OH)D (12.8 ± 3.7 vs. 8.7 ± 5.1 ng/mL) and lower VDBP concentrations (201.8 ± 45.0 vs. 216.0 ± 68.2 μg/ mL) than control women. The association between these two vitamin D related-biomarkers and femur neck BMD were confirmed through univariable and multivariable linear model analysis. Although lumbar BMD did not differ between groups, the agricultural group displayed a lower femur BMD and a 4.3-fold increase in the risk of osteoporosis compared with the control group.
Conclusions
Women working in agriculture showed lower femur BMD than the control group. Of the vitamin D-related biomarkers tested, bioavailable 25(OH)D and VDBP were associated with BMD. As bioavailable 25(OH)D levels are affected mainly by VDBP levels, VDBP may play a role in the lower femur neck BMD values observed in the agricultural group. Thus, the measurement of VDBP concentration might be considered a simple and non-invasive method for measuring bone health status.

OBJECTIVE: The purpose of this study was to evaluate the effect of CCB treatment on the survivability and in vitro development of mouse oocyte frozen by vitrification. METHODS: Mouse oocytes retrieved from cycle stimulated by PMSG and hCG were treated by CCB and then exposed to EFS-30. These oocytes were placed onto an EM grid and submerged immediately in liquid nitrogen. Thawing of the oocytes on EM grid was carried out at room temperature for 5 seconds, then the EM grid was placed into 0.75 M sucrose at 37degrees C for 3 minutes. This was followed by 0.5 M and 0.25 M sucrose for 3 minutes, each. We compared the survivability, cleavage and developmental rate of mouse frozen by vitrification between CCB treated and non-treated groups. Chi-square was used to determine statistical significance. statistical significance was defined as p<0.05. RESULTS: Survivability (79.3%) and developmental rate into blastocyst (52.3%) of mouse oocyte were markedly decreased after vitrification. There were no significant differences between CCB treated and non- treated groups regarding survivability of oocyte frozen by vitrification (80.3% vs 78.5%). The developmental rate into 2-cell in CCB treated group was significantly higher than that in non-treated group (69.7% vs 61.9%, p<0.05). The developmental rate into blastocyst in CCB treated group was higher than that in non-treated group (54.9% vs 51.5%), but the difference was not significant. CONCLUSION: Survivability of mouse oocyte could not be affected by CCB treatment and developmental rate into 2-cell was improved in CCB treated group. It is suggested that CCB treatment prior vitrification improve stability of cytoskeleton and then improve fertilization and early stage embryo development.
