One hundred eighty-eight patients with avascular necrosis of the femoral head in adults, who were admitted and treated in Department of Orthopedic Surgery, Seoul National University Hospital between January of 1965 and May of 1985 are investigated in terms of the history, clinical data and laboratory examinations. And, the following results were obtained. 1. The incidence was higher in the 5th decade and the sex ratio between male and female was 3.3:l. 2. 106 cases (56%) had the bilateral hip involvement. 3. The most frequent etiological factor was alcohol (72 cases, 38%), followed by trauma (35 cases, 19 %), and steroid (32 cases, 17%). 4. Underlying diseases in steroid-induced avascular necrosis of the femoral head were dermopathy (9 cases), nephropathy (4 cases), pain over other joints (5 cases), systemic lupus erythematosus (2 cases), etc. 5. The time intervals between etiological events and appearances of clinical symptoms were 2 years and 3 months in the steroid induced cases, 1 year and 1 month in trauma induced ones, 2 years and 1 month in femur neck fracture cases, 2 years and 2 months in Caissons disease, and 3 years in post-irradiation 6. Bone scan was valuable in the early diagnosis of avascular necrosis of the femoral head. 7. Selective femoral head angiography show narrowing of lateral femoral circumflex artery, narrowing or obstruction of medical femoral circumflex artery, and obstruction of superior retinacular artery. 8. It is suggested that minor trauma and osteoporosis could make micro-fracture, resulting avascular necrosis of the femoral head, and the vascular change is secondary to the avascular necrosis.

We describe an ovarian mucinous cystadenocarcinoma with a sarcoma-like mural nodule. In the literature, rare cases of ovarian mucinous tumors have been described which contain foci of undifferentiated carcinoma, sarcoma, and sarcoma-like nodules. The distinction between these lesions is important because of poorer prognosis of true sarcoma and anaplastic carcinoma than sarcoma-like mural nodules. This case shows different results of immunohistochemical stain for anaplastic carcinoma.

Lipomas of the heart are benign neoplasms and have rarely been described. Due to the fact that they normally cause no symptoms, diagnosis is often purely accidental. Because of the rarity of these tumors, it seems worthwhile to present an example studied at autopsy. It was associated with the sudden death of a 15-year-old boy. The tumor arose from the wall of the left ventricle and occupied the pericardial cavity, measuring 13x7x6 cm in size. The tumor was whitish-yellow, translucent, and soft. Microscopically, the tumor was composed of mature adipose tissue which extended between muscle fibers. This current case, the giant cardiac lipoma is believed to produce disturbances of the conduction system and distrubances of cardiac filling.

The purpose of this study was to investigate the morphologic changes of the bile canaliculi and its associated structures of the liver induced by common bile duct ligation(CBDL) in the rat. The canalicular surface and lateral surface of the dry-fractured hepatocytes was studied with scanning electron microscopy at 1~6 weeks post ligation. The first week after CBDL, the bile canaliculi were dilated. The microvilli were increased in number and the lumens contained granular materials After 2 weeks or more, the bile canaliculi were dilated to a variable degree, and with irregularity, measuring from 1.5 to 5 micrometer in diameter, and in the advanced stage, the canaliculi showed blunting and the disappearance of microvilli. Some canaliculi had sprouting side branches. At 4~6 weeks post-ligation, the lateral surface of the hepatocytes also showed some irregularity and a tortuous appearance, and numerous small sized microvillous projections were formed. The tubular structures of the proliferated SER distributed adjacent to the lateral surface of the hepatocytes, and the direct connection of a tubular structure and the cytoplasmic membrane was observed. These results suggest that the deformity and loss of microvilli of bile canaliculi reflect the disturbance of bile secretion from the hepatocytes. And prolonged obstruction of bile flow may result in bile excretion via the lateral surface of hepatocytes.

PURPOSE: The study was to get basic data on the well-being of middle-aged people concerning their preparation for their upcoming old age and their quality of life. METHODS: The subjects were 440 people aged between 40 and 59 living in Seoul and Gyeonggi-do. RESULTS: First, physical preparation for old age was affected by religion, children, health, monthly income, and economical status, and these factors were shown statistically significant. Emotional preparation and spiritual preparation were also related to the above-mentioned factors. Secondly, in the subjects' mental picture, a nursing home was a place for the aged without anyone who is going to take care of them and without abilities to care of themselves. Preference for nursing home was based on two factors, i.e., nursing and treatment care, and the cost was about one million won per month. Also they wanted that the government should pay a certain amount for private users. CONCLUSION: Therefore, people should lead a life of good health-related habits along with economical preparation for their old age.

PURPOSE: The purpose of this study was to analyze differences in health behaviors among adolescents in order to provide fundamental data to develop an effective body weight control program. METHODS: Secondary analysis was done using data from the 9th (2013) Online Survey on Ado-lescents' Health Behaviors by the Korea Centers for Disease Control and Prevention. The adolescents were divided into low weight, normal weight, overweight, and obesity groups according to body mass index (BMI). Differences in health behaviors were analyzed. RESULTS: Gender, grade, socioeconomic status, perceived-health status, exercise, breakfast, fast food, ramen noodles, snacks, carbonated soft drinks, fruits and vegetables, satisfaction with sleep, stress, smoking, and alcohol consumption were significantly different among the groups. Ingestion of carbonated soft drinks and snacks was significantly higher in the low weight group compared to the normal weight group. Eating fast foods, ramen noodles, and snacks was significantly lower in the overweight and obesity groups compared to the normal weight group. CONCLUSION: Findings indicate that health behaviors among the groups differ from traditional knowledge about obesity. To develop optimal programs and improve efficacy, prior knowledge should be used to think differently and individualized programs should be based on an understanding health behaviors of adolescents.
