Congenital lipoid adrenal hyperplasia, the most severe form of congenital adrenal hyperplasia, is caused by mutations in the steroidogenic acute regulatory protien (StAR). It is characterized by failure of synthesis of all three classes of adrenal steroids and massive accumulation of lipids and cholesterol in the adrenal cortex. The computed tomography (CT) unequivocally delineated massively enlarged adrenal glands of fat-tissue attenuation, enabling early diagnosis and replacement therapy. We report a case of congenital lipoid adrenal hyperplasia, in which CT established that lipoid deposition at the adrenal cortex disappeared after the adrenal hormone replacement therapy.

The purposes of this study were to investigate the perception and needs of community nutrition programs for 379 community residents of 23 health centers where the pilot community nutrition programs are intervening. The awareness rate of the nutrition programs was 54.3% and the reason of the awareness was mainly happened to know when visiting health centers'. More than 90% of the respondents responded that public health nutrition services are necessary. But the residents who experienced the nutrition services showed higher needs of the programs(97.3%) and improved the impression about the roles of health centers(93.6%). They also showed a higher rate of balanced dieting, stronger intentions to change their inappropriate eating style and a higher practicing rate. The more they believed in the provided nutrition information, the more they showed concerns about their diet and practicing rate of the advices from nutritionists. These results show the positive and successful impact of the pilot nutrition programs on the community residents. We need strategies for a more active improvement of the programs and to maintain more qualified public health nutritionists to carry out targeted community nutrition programs.

The uptake of glucose for metabolism and growth is essential to most animal cells and is mediated by glucose-transporter (GLUT) proteins. The aim of this study was to determine which class of glucose transporter molecules was responsible for uptake of glucose in the mouse early embryo and at which stage the corresponding genes were expressed. In addition, co-culture system with vero cell was used to investigate the effect of the system on GLUT expression. Two-cell stage embryos were collected from the superovulated ICR female and divided into 3 groups. As a control, embryos were cultured in 0.4% BSA-T6 medium which includes glucose. For the experimental groups, embryos were cultured in either co-culture system with vero cells or glucose-free 76 medium supplemented with 0.4% BSA and pyruvate as an energy substrate. 2-cell to blastocyst stage embryos in those groups were respectively collected into microtubes (50 embryos/tube). Total RNA was extracted and RT-PCR was performed. The products were analysed after staining ethidium bromide by 2% agarose gel electrophoresis. Blastocysts were collected from each group at 120hr after hCG injection. They were fixed in 2.5% glutaraldehyde, stained with hoechst, and mounted for observation. In control, GLUT1 was expressed from 4-cell to blastocyst. GLUT2 and GLUT3 were expressed in morula and blastocyst. GLUT4 was expressed in all stages. When embryos were cultured in glucose-free medium, no significant difference was shown in the expression of GLUTI1, 2 and 3, compared to control. However GLUT4 was not expressed until morular stage. When embryos were co-cultured with vero cell, there was no significant difference in the expression of GLUT1, 2, 3 and 4 compared to control. To determine cell growth of embryos, the average cell number of blastocyst was counted. The cell number of co-culture (93.8+/-3.1, n=35) is significantly higher than that of control and glucose-free group (76.6 +/- 3.8, n=35 and 68.2+/-4.3, n=30). This study shows that the GLUT genes are expressed differently according to embryo stage. GLUTs were detectable throughout mouse preimplantation development in control and co-culture groups. However, GLUT4 was not detected from 2- to 8-cell stage but detected from morula stage in glucose-free medium, suggested that GLUT genes are expressed autocrinally in the embryo regardless of the presence of glucose as an energy substrate. In addition, co-culture system can increase the cell count of blastocyst but not improve the expression of GLUT. In conclusion, expression of GLUT is dependent on embryo stage in preimplantation embryo development.

Gastritis cystica superficialis (GCS) is a rare lesion which is characterized by glandular hyperplasia with regeneration and degeneration in the mucosa and muscularis mucosa. Recently, GCS is revealed as precancerous lesion, but most report has been associated with those found at the site of a gastroenterostomy. So, we report two cases with GCS who had not previous gastric surgery. A 45-year-old woman visited for epigastric discomfort and another 4Q-year-old woman for epigastric pain. They had not undergone any gastric surgery. The gastroscopy discovered one polyp on anterior wall of greater curvature, upper body and another polyp in the center of the fold of greater curvature, lower body. We removed it by snare polypectomy and the histologic finding showed the character of GCS.

OBJECTIVES: Seoul-Activities of Daily Living(S-ADL) was developed to assess elderly person's basic activities of daily living. This study aims to develop standardized ADL assessment scale and confirm the reliability and validity of the S-ADL. METHODS: It was participated in 336 controls and 145 patients diagnosed Alzheimer's disease. RESULTS: In controls, it was statistically significant to age, but not sex, education, region and presence of spouse. Also, reliability and validity were statistically significant. Principal axis factoring analysis revealed three factors that accounted for 66.67% of the total variance(1.self-care/hygiene, 2.ambulation, 3.toileting). According to each CDR stage, there were significant difference, except for CDR 0.5 and CDR 1 suggesting early dementia. Particularly, it was remarkable for functional impairment in CDR 2 and CDR 3 suggesting moderate to severe dementia. The order of the loss of function was (1) self-care/hygiene, (2) toileting, and (3) ambulation. CONCLUSIONS: Our study showed that the S-ADL could be a very reliable and valid tool for the assessment of functional disabilities of Korean dementia patients. Particularly, S-ADL would be useful in assessing daily function of moderate to severe AD.

It is well known that the bona pellucidae of mouse oocytes become 'hardened' when they are allowed to mature in vitro in the absence of serum components. To see if oocytes already undergone meiotic resumption in vivo exhibit similar zona hardening, hardening of ZP of cumulus-enclosed oocytes(CEOs) was examined after culture in vitro since their release from follicles various hours after hCG injection. When CEOs matured in vivo for 3h or longer were subjected to culture in vitro for 14h with BSA alone, zona hardening was significantly reduced compared to those cultured in vitro from the begining of maturation. However, when CEOs matured in vivo for 5h were freed from cumulus cells and then cultured in vitro with BSA alone, little reduction of zona hardening was observed. Preincubation of CEOs for 5h with fetuin, one of the well known inhibitor of in vitro zone hardening, did not prevent bona hardening during its subsequent culture of CEOs for 14h without fetuin. However, when CEOs precultured with both fetuin and PMSG for 5h and then further cultured with BSA alone for 14h, zona hardening was dramatically reduced. Under these conditions, the expansion of cumulus cell was observed. In addition, CEOs cultured with both BSA and dbcAMP to prevent their meiotic resumption showed a significant increase of zona hardening. Whether the observed zona hardening was correlated with the conversion of ZP2 to ZP2f was examined. Zona pellucida, isolated from CEOs matured for 5h in vivo and then further cultured with BSA alone was subjected to SDS-PAGE. Most of ZP2 molecules from these CEOs did not undergo conversion from ZP2 to ZP2f. From these results, it is concluded that CEOs undergone meiotic resumption in vivo do not exhibit bona hardening when they were subsequently cultured in vitro without serum components. It appears that cumulus cells play an important role in this phenomenon.

Diabetes & Metabolism Journal 2024;48(2):215-230
Background:
Previous studies have reported that oxidative stress contributes to obesity characterized by adipocyte hypertrophy. However, mechanism has not been studied extensively. In the current study, we evaluated role of extracellular vimentin secreted by oxidized low-density lipoprotein (oxLDL) in energy metabolism in adipocytes.
Methods:
We treated 3T3-L1-derived adipocytes with oxLDL and measured vimentin which was secreted in the media. We evaluated changes in uptake of glucose and free fatty acid, expression of molecules functioning in energy metabolism, synthesis of adenosine triphosphate (ATP) and lactate, markers for endoplasmic reticulum (ER) stress and autophagy in adipocytes treated with recombinant vimentin.
Results:
Adipocytes secreted vimentin in response to oxLDL. Microscopic evaluation revealed that vimentin treatment induced increase in adipocyte size and increase in sizes of intracellular lipid droplets with increased intracellular triglyceride. Adipocytes treated with vimentin showed increased uptake of glucose and free fatty acid with increased expression of plasma membrane glucose transporter type 1 (GLUT1), GLUT4, and CD36. Vimentin treatment increased transcription of GLUT1 and hypoxia-inducible factor 1α (Hif-1α) but decreased GLUT4 transcription. Adipose triglyceride lipase (ATGL), peroxisome proliferator-activated receptor γ (PPARγ), sterol regulatory element-binding protein 1 (SREBP1), diacylglycerol O-acyltransferase 1 (DGAT1) and 2 were decreased by vimentin treatment. Markers for ER stress were increased and autophagy was impaired in vimentin-treated adipocytes. No change was observed in synthesis of ATP and lactate in the adipocytes treated with vimentin.
Conclusion
We concluded that extracellular vimentin regulates expression of molecules in energy metabolism and promotes adipocyte hypertrophy. Our results show that vimentin functions in the interplay between oxidative stress and metabolism, suggesting a mechanism by which adipocyte hypertrophy is induced in oxidative stress.

OBJECTIVE: Zarit Burden Interview (ZBI) was the most commonly used measure of caregiver burden for demented older adults. The aim of this study was to investigate dimensions of caregiver burden through factor analysis of ZBI. METHODS: The participants were 706 outpatients with dementia and their caregivers in Korea. We assessed the caregiver burden using the Korean version of ZBI. The participants were randomly divided into two groups, for the purpose of identifying the most optimal factor structure through exploratory factor analysis in group 1 (n=368) and confirmatory factor analysis in group 2 (n=338). RESULTS: The results of exploratory factor analysis in group 1 suggested 3-factor structure, which was labeled ‘personal strain,’‘patient dependency,’ and ‘self-criticism.’ The confirmatory factor analysis results indicated the 3-factor structure which was discovered through exploratory factor analysis was the best-fitting model for explaining the caregiver burden in group 2. CONCLUSION: The current study has significant implications for advancing our understanding of ZBI as multidimensional burden scale. Furthermore, differentiating the dimensions may allow researchers to assess the effects of interventions more precisely.

BACKGROUND AND PURPOSE: Previous studies have reported conflicting results about the prevalence of seizures in Alzheimer's disease (AD). There are few epidemiological studies on this topic in Asia. Thus, the objective of this study was to examine demographic and clinical characteristics as well as incidence for seizures in AD patients compared to non-AD patients in a prospective, longitudinal, community-based cohort with a long follow-up. METHODS: Data were collected from National Health Insurance Service-National Elderly Cohort (NHIS-elderly) Database to define patients with AD from 2004–2006 using Korean Classification Diseases codes G30 and F00. We performed a 1:5 case-control propensity score matching based on age, sex, and household income. We conducted Cox proportional hazards regression analysis to estimate the risk of epilepsy in AD patients. RESULTS: In the cohort study, patients with AD had higher risk for epilepsy than those without AD, with hazard ratio of 2.773 (95% confidence interval [CI], 2.515–3.057). This study also showed that male gender and comorbidities such as hypertension, hyperlipidemia, diabetes, and chronic kidney disease increased the risk of developing epilepsy. Patients with AD had 1.527 (95% CI, 1.375–1.695) times higher mortality rate than those in the control group. CONCLUSIONS: AD patients have significantly higher risk of developing epilepsy than non-AD patients.
