This study examined whether adult bovine muscle satellite cells from 30-month-old Hanwoo cattle are multipotential. The satellite cells were found to have the potential to proliferate and differentiate into myoblasts with the formation of multinucleated cells. In addition, treatment with the peroxisome proliferator activating receptor-${\gamma}$ ($PPAR{\gamma}$) agonist, rosiglitazone, promoted their trans-differentiation into adipocytes with significant increases in glycerol accumulation and glycerol-3-phosphate dehydrogenase activity. Western blot analysis revealed that increased levels of the adipocyte fatty acid-binding protein, $PPAR{\gamma}$ and of CCAAT/enhancerbinding protein were closely related to rosiglitazoneinduced differentiation of the cells. These findings demonstrate that satellite cells from adult Hanwoo cattle are multipotent, and that their trans-differentiation into adipocytes can be induced by rosiglitazone.

The purpose of this study was to determine the drinking behaviors and drinking problems of adult, mentally retarded persons over 18 years old. It was also investigated whether gender, age, and pattern of employment create different result of drinking behaviors and drinking problems, and the variables explaining drinking problems were analyzed. One hundred forty adults, mentally retarded persons were surveyed in Seoul and KyeongGi area. The major findings were as follows; The majority of respondents ($58.2\%$) reported that they had consumed alcohol beverages sometimes prior to their having been interviewed. The average age of respondents who had consumed alcohol was 26.4 years and average age of first-use of alcohol was 22 years. For consumption frequency, $39.2\%$ of respondents reported that they drink alcohol once a month. Average alcohol consumption per occasion was 1.5 cups, and $10.9\%$ of respondents answered more than 5 cups per occasion. Regarding problems associated with drinking, $16\%$ of respondent of AUDIT and $51.4\%$ of Family CAGE answered that their children have drinking-related problems. Men drink more than women and experience more alcohol problems. Supervised employment group was the group with the greatest prevalence for drinking. For the amount of drinking, gender and employment pattern showed significant differences. Drinking problems (AUDIT and Family CAGE) of adult, mentally retarded persons were influenced by age of first-use of alcohol, frequency of alcohol use, and alcohol consumption.

The objective of this study was to investigate the fit preference for ready-to-wear clothes(jackets and slacks) of adult men and to determine the respective differences by the age range and obesity level. The study method was a questionnaire survey with 465 male subjects aged from 20 to 59 years old. The questionnaire was composed of fit preference tendency, physical measurements, age, and occupation. The findings were as follows. 1. Regarding the fit preferred for each part of jackets and slacks, among ready-to-wears, the 'thing with some extra width' in every part was most favored, followed by the 'thing fitting perfectly'. 2. Differences were found in the fit preference tendency by the age of adult men. The fit preference tendency was higher among those in their 20's than among those of the other age ranges. 3. Differences were also found in the fit preference tendency by the obesity level of adult men. The fit preference tendency was higher in the order of the emaciation, normalcy, and obesity types. 4. The fit preference tendency was more affected by age than by obesity level. Clothing companies should consider ease to offer the proper clothing desired by consumers.

Adult fibrosarcoma is a malignant tumor comprising of spindle-shaped fibroblasts with variable collagen production. Due to their aggressive nature and high probability of local tumor recurrence, these tumors require accurate diagnosis and resection according to guidelines. A 57-year-old male presented to the clinic with a complaint of a palpable growing mass in the left scapular area. Examination of the back revealed a 6 cm protruding tumor with a nodular surface. We performed a wide excision, including the infraspinatus fascia layer and subsequent reconstruction using a parascapular island flap. Histopathological analysis demonstrated the typical microscopic features of adult fibrosarcoma. At the 3-year follow-up, there was no evidence of local recurrence and the resection margin was completely clear of tumor.

본 연구는 노인이 되어 자신의 노화로 인한 어려움을 지니면서도 여전히 성인 장애자녀의 보호역할의 책임을 지니며 살고 있는 노인부모의 실태와 노후생활을 위한 보건복지 욕구를 고찰하여 향후 고령화가 지속되면서 복합화 되는 노인문제에 대한 체계적 연구와 정책적 관심의 필요성을 제기하고자 시도하였다. 성인 장애자녀를 돌보는 65세 이상의 저소득 노인부모를 대상으로 하였으며, 일반적 특성, 장애자녀특성, 노후생활 준비 및 보건복지 서비스 이용 및 필요성에 대한 욕구를 조사하였다. 성인 장애자녀를 돌보는 저소득 노인 부모는 신체적 노화와 함께 오랜 기간 동안 장애자녀를 돌보면서 치료 및 재활과 관련된 비용의 지속적인 지출, 사회 활동의 단절이라는 복합적 원인에 의해 노후생활 전반에 걸쳐 어려움을 경험하고 있었다. 이러한 노인부모의 경제적 어려움, 신체적 쇠약함, 그리고 여전히 끝나지 않은 자녀 돌봄의 역할은 이들의 노후생활을 위한 보건 복지 서비스 이용 및 욕구형성과 밀접한 관련성을 나타냈다. 성인장애자녀를 돌보는 대부분의 노인부모는 자신의 노후생활을 위한 준비를 전혀 하지 못하는 것으로 나타났으며, 이는 자녀의 장애기간과 관련이 있었다. 제공되고 있는 보건복지 서비스는 현물 형태의 직접적이고 수혜적인 성격이 강한 서비스를 주로 이용하였고, 좀 더 자발적이면서 추가적인 비용이 요구되는 사회정서적 영역에 대한 서비스 이용 및 필요도에 대한 인지는 낮게 나타났다. 따라서 향후 장애자녀를 돌보는 노인부모의 질적인 노후생활을 위한 대응방안 모색은 장애자녀의 사회통합이라는 목표와 함께 장기적인 측면에서 연구될 필요성이 있으며, 이러한 현실과 상황에 대한 이해를 바탕으로 이들을 위한 체계적인 지원프로그램 개발에 대해 지속적인 논의가 진행되어야 할 것이다.

Purpose: The purpose of the present study was to investigate the prevalence and lifestyle factors related to the metabolic syndrome in Korean elderly. Methods: A total number of 122 elderly over 60 yr were recruited from a community elderly center. Elderly were classified into young old (60-74 yr) and old (75-84 yr). Metabolic syndrome was defined by third report of the national cholesterol education program (NCEP) expert panel on Adult Treatment Panel III (ATP III). Abdominal obesity was determined by Korean society for the study of Obesity criteria. The nutritional status was measured by mini nutritional assessment (MNA). Results: The prevalence of the metabolic syndrome was significantly higher in the old than young old elderly (p<0.05, respectively). Abdominal obesity and hypertension were the most common risk factors. The related factors to metabolic syndrome were high Body mass Index (BMI) and currently not participating in exercise. Abdominal obesity, low HDL cholesterol and hypertension were associated with specific nutrient intakes. Conclusion: A strategy to decrease the metabolic syndrome in the elderly is urgently needed particularly so for the old elderly. A nutritional and exercise program for young old elders may be helpful reducing the prevalence of metabolic syndrome in later stage.

Pulmonary hamartoma is often incidental, asymptomatic finding on routine chest roentgenogram. It has been considered a congenital malformation. Since the original description by Albrecht in 1908, it has been classified into two types, a small, fibrocartilaginous mass in adults, and a cystic lobar mass in infants. We experienced two cases of pulmonary hamartoma which proved to be the adult form of hamartoma. One was located in left upper lobe of a 58 year old male patient, the other was located in the perihilar region of the right middle lobe of a 38 year old male patient. The former case was treated by wedge resection: the latter by right middle lobectomy and the postoperative courses of both cases were very good and without complication.

Effects of $\alpha$-difluoromethylornithine (DFMO) and $\alpha$-difluoromethylarginine (DFMA), inhibitors of polyamine syntheic enzymes (ornithine decarboxylase, arginine decarboxylase), on ovary were investigated during pupal-adult development of Helicoverpa assulta. Two inhibitors (DFMO, DFMA) showed definite inhibition effects on ovarian development. The inhibition effect on ovaries weight was more marked in DFMA-injection than that observed in DFMO-injection. Two inhibitors (DFMO, DFMA) gave rise to a peculiar decrease in ornithine decarboxylase (ODC) or arginine decarboxylase (ADC) activity in ovaries, 72 hrs (5-day old pupa) post injection. However, DFMO clearly exhibited supression of ODC activity after 96 hrs (6-day old pupa). In addition, two inhibitors (DFMO, DFMA) diminished putrescine content in the ovary. The spermidine level was slightly decreased by each injection of the inhibitors. However, two inhibitors (DFMO, DFMA) raised the spermine content at certain developmental stages in the ovary. Although the effect of DFMA was less severe, two inhibitors (DFMO, DFMA) caused not only an overall delay in ovarian development, but also abnormalities in cellular differentiation. Noted effects in the pupal ovary were the appearance of irregular nurse cells and partial destruction of follicle epidermal cells. Adult ovary showed rapid degradation of nurse cells, a reduction in the number of follicle epidermal cells and immature oocytes that had a low yolk content.
