BACKGROUND: Recently, according to many studies, variable factors have been known to be associated with physical fitness. The factors such as obesity and inactivity are associated with poor physical fitness, but regular exercise is associated with good physical fitness. In our country, these studies are not yet reported. And so, this study was designed to investigate the factors associat,ed with physical fitness. METHODS: From May 1st, until July 30th 1996, we recruited the 411 subjects who visited the Health Promotion Center at Seoul National University Hospital. Data related to sex, age, exercise, job, cigarette smoking, alcohol consumption were obtained by self-administered Questionnaire. Obesity index was calculated by the percentage of standard body weight. And VO2max were obtained by submaximal bicycle ergometer test. High level exercise group was defined as the persons who had taken exercise more than 3 times a week and 20 minutes per session, and moderate exercise group was defined as the persons who had taken exercise one or two times a week and 20 minutes per session, and sedentary group was defined as the persons who had taken exercise more than 20 minutes less than one time per week. RESULTS: The subjects were 230 males(56%), total numbers were 411. The results were as follows. Compaired to women and nonexercise group, men and exercise group had high VO2max(p<0.005). The relationship between VO2max and age showed negative, and the VO2max of obese group(obesity index>_120) was greater than that of nonobese group. Any significant relationships between VO2max and job, disease were not found. In multiple regression analysis, significant relationships between VO2max and age, sex, exercise type, and obesity index were observed(p<0.01). CONCLUSIONS: We concluded that there were significant relationships between VO2max and obesity index, exercise group.

Permanent neonatal diabetes mellitus refers to diabetes that occurs before the age of 6 months and persists through life. It is a rare disorder affecting one in 0.2-0.5 million live births. Mutations in the gene KCNJ11, encoding the subunit Kir6.2, and ABCC8, encoding SUR1 of the ATP-sensitive potassium (K(ATP)) channel, are the most common causes of permanent neonatal diabetes mellitus. Sulfonylureas close the K(ATP) channel and increase insulin secretion. KCNJ11 and ABCC8 mutations have important therapeutic implications because sulfonylurea therapy can be effective in treating patients with mutations in the potassium channel subunits. The mutation type, the presence of neurological features, and the duration of diabetes are known to be the major factors affecting the treatment outcome after switching to sulfonylurea therapy. More than 30 mutations in the KCNJ11 gene have been identified. Here, we present our experience with a patient carrying a novel p.H186D heterozygous mutation in the KCNJ11 gene who was successfully treated with oral sulfonylurea.

This study was undertaken to investigate the protective effect of rice bran oil (RBO) on amyloid β protein (Aβ) (25-35)-induced memory impairment and brain damage in an ICR mouse model. Memory impairment was produced by intracerebroventricular microinjection of 15 nmol Aβ (25-35) and assessed using the passive avoidance test. Treatment with RBO at 0.1, 0.5, or 1 mL/kg (p.o. daily for 8 days) protected against Aβ (25-35)-induced memory impairment. Furthermore, Aβ (25-35)-induced decreases in glutathione and increases in lipid peroxidation and cholinesterase activity in brain tissue were inhibited by RBO, and Aβ (25-35)-induced increases of phosphorylated mitogen-activated protein kinases (MAPKs) and inflammatory factors, and changes in the levels of apoptosis-related proteins were significantly inhibited by RBO. Furthermore, Aβ (25-35) suppressed the PI3K/Akt pathway and the phosphorylation of CREB, but increased phosphorylation of tau (ptau) in mice brain; these effects were significantly inhibited by administration of RBO. These results suggest that RBO inhibits Aβ (25-35)-induced memory impairment by inducing anti-apoptotic and anti-inflammatory effects, promoting PI3K/Akt/CREB signaling, and thus, inhibiting p-tau formation.

Oak tree death caused by symbiosis of an ambrosia beetle, Platypus koryoensis, and an ophiostomatoid filamentous fungus, Raffaelea quercus-mongolicae, has been a nationwide problem in Korea since 2004. In this study, we surveyed the yeast species associated with P. koryoensis to better understand the diversity of fungal associates of the beetle pest. In 2009, a total of 195 yeast isolates were sampled from larvae and adult beetles (female and male) of P. koryoensis in Cheonan, Goyang, and Paju; 8 species were identified by based on their morphological, biochemical and molecular analyses. Meyerozyma guilliermondii and Candida kashinagacola were found to be the two dominant species. Among the 8 species, Candida homilentoma was a newly recorded yeast species in Korea, and thus, its mycological characteristics were described. The P. koryoensis symbiont R. quercusmongolicae did not show extracelluar CM-cellulase, xylanase and avicelase activity that are responsible for degradation of wood structure; however, C. kashinagacola and M. guilliermondii did show the three extracellular enzymatic activities. Extracelluar CM-cellulase activity was also found in Ambrosiozyma sp., C. homilentoma, C. kashinagacola, and Candida sp. Extracelluar pectinase activity was detected in Ambrosiozyma sp., C. homilentoma, Candida sp., and M. guilliermondii. All the 8 yeast species displayed compatible relationships with R. quercus-mongolicae when they were co-cultivated on yeast extract-malt extract plates. Overall, our results demonstrated that P. koryoensis carries the yeast species as a symbiotic fungal associate. This is first report of yeast diversity associated with P. koryoensis.

Townes-Brocks syndrome (TBS) is a rare genetic disorder characterized by the classic triad of congenital anomalies of the anus, thumbs, and ears, with variable expressivity. Additionally, renal malformations, cardiac anomalies, and endocrine and eye abnormalities can accompany TBS, although less frequently. TBS is inherited in an autosomal dominant fashion; however, about 50% of patients have a family history of TBS and the remaining 50% have de novo mutations. SALL1, located on chromosome 16q12.1, is the only causative gene of TBS. SALL1 acts as a transcription factor and may play an important role in inducing the anomalies during embryogenesis. Clinical features of TBS overlap with those of other multiple anomaly syndromes, such as VACTERL syndrome, Baller-Gerold syndrome, Goldenhar syndrome, cat eye syndrome, and Holt-Oram syndrome. Consequently, there are some difficulties in differential diagnosis based on clinical manifestations. Herein, we report a Korean family with two generations of TBS that was diagnosed based on physical examination findings and medical history. Although the same mutation in SALL1 was identified in both the mother and the son, they displayed different clinical manifestations, suggesting a phenotypic diversity of TBS.

Langerhans cell histiocytosis is a rare disease in children. However, Langerhans cell histiocytosis encompasses a wide spectrum of clinical presentations and mimics other conditions. A 1-year-old boy presented with signs of periorbital cellulitis that initially responded to antibiotics, but remained as a same-sized mass with serial orbital computed tomography. The lesion was partially excised. Histopathology and immunohistochemical staining confirmed the diagnosis of Langerhans cell histiocytosis. This case demonstrates that in patients with periorbital cellulitis which has relapsed or responded inadequately to antibiotics, further investigation should initiated to rule out other inflammatory causes.
