The purpose of this study was to explore the relationship between dietary behavior and the nutrient intake status in the youth of rural areas, based on their personal characters such as their sex, age, family type, number of family members, mother's age, occupation, and school career. This study was made by use of a self-administrated questionnaire with a 24-hour recall for 5days as an instrument with 439 randomly selected students. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-wallis test, x2-test by contingence table, and Spearman's correlation coefficient in non parametric statistical cases. Some of the interesting results are as follows : 1) The correlation between sex and breakfast is highly significant. That is, over 80% of male students had breakfast every day, whereas only about 60% of female students had breakfast every day. Bad table manners and some other problems are insignificant with respect to the personal characters in the relations between the personal characters and eating behaviors. However, the regularity of every meal, the frequency of having meals with other family members, and the frequency of meals eaten out and snacks show significant differences. 2) The mother's occupation does not have any influence on the nutrient intake of their students when the relationship between personal characters and nutrient intake was analysed. On the other hand sex, the mother's school career, the numbers of family members, the type of family, and the income of the family showed significant differences nutrient intakes. 3) The regularity and the frequency of having meals, meals eaten out with their family members, and the table manners during meals showed significant differences in the intake of nutrient elements such as calorie, protein, fat, fiber, calcium, iron, phosphorus, vitamin B1, vitamin B2, niacin and vitamin C. However some consideration during meals and problems in eating habit are insignificant with regard to nutrient intake.

Dyke-Davidoff-Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-avidoff-Masson Syndrome, in a 6/12 year-old boy and a 1, 10/12 year-old girl who were admitted to our department of pediatrics, because of convulsion and hemiparesis The brain CT scan showed marked dilatation of lateral ventricle, prominent sylvian fissure and cortical sulci. So we report two cases of Dyke-Davidoff-Masson syndrome with review of literature.

BACKGROUND: Pulmonary Langerhans cell histiocytosis forms part of a spectrum of diseases that are characterized by a monoclonal proliferation and infiltration of organs by Langerhans cells. Several organ systems may be involved in Langerhans cell histiocytosis, including the lungs, bone, skin, pituitary gland, liver, lymph nodes and thyroid. Pulmonary histiocytosis X represents 2.8% of interstitial lung disease. Here we present the clinical, radiological, therapeutic aspects of pulmonary histiocytosis X. METHOD: Fourteen cases of biopsy-proven pulmonary histiocytosis X patients who were diagnosed in Seoul National University Hospital during the period from January 1990 to December 1998 were analyzed retrospectively. RESULT: There were 12 men and 2 women in this study. The initial presenting symptoms were dyspnea, cough, chest pain, which was associated with the pneumothorax, and chest radiography abnormalities. Only 8 patients (57%) were smokers. There were 5 patients with extra-pulmonary histiocytosis (pituitary, bone, skin). Eight patients had received the chemotherapy. There were no mortalities and only one patient experienced an aggravation of symptom during the follow-up period. CONCLUSION: In contrast to previous reports from other countries, the patients with pulmonary histiocytosis X in this study presented with several different clinical characteristics, such as a male predominance, relatively low smoker's rate, and a better prognosis.

BACKGROUND: Numerous studies of safe, long term preservation for lung transplantation have been performed using ex vivo models or in vivo single lung transplantation models. However, a safe preservation time which is applicable for clinical use is difficult to determine. We prepared LPDG solution for lung preservation study. In this study we examined the efficacy of LPDG(low potassium dextran glucose) solution in 24-hour lung preservation by using a sequential bilateral canine lung allotransplant model. MATERIAL AND METHOD: Seven bilateral lung transplant procedures were performed using weight-matched pairs(24 to 25kg) of adult mongrel dogs. The donor lungs were flushed with LPDG solution and maintained hyperinflated with 100% oxygen at 10C degrees for a planned ischemic time of 24 hours for the lung implanted first. After sequential bilateral lung transplantation, dogs were maintained on ventilators for 3 hours: arterial resistance were determined if the recipients hourly after bilateral reperfusion and compared with pretransplant-recipient values, which were used as controls. After 2hours of reperfusion, the chest X-ray, computed tomogram and lung perfusion scan were performed for assessmint of early graft lung function. Pathological examinations for ultrastructural findings of alveolar structure and endothelial structure of pulmonary artery were performed. RESULT: Five of seven experiments successfully finished the whole assessments after bilateral reperfusion for three hours. Arterial oxygen tension in the recipients was markedly decrased in immediate reperfusion period but gradually recovered after reperfusion for three hours. The pulmonary artery and pulmonary vascular resistance showed singificant elevation(p<0.05 versus control values) but also recovered after reperfusion for three hours(p<0.05 versus immediate period value). The ultrastructural findings of alveolar structure and endothelial structure of pulmonary artery showed reversible mild injury in 24 hours of lung perservation and reperfusion. CONCLUSION: This study suggests that LPDG solution provides excellent preservation in a canine model in which the dog is completely dependent on the function of the transplanted lung.

An anomalous systemic arterial supply to the normal basal segments of the left lower lobe without sequestration is a rare congenital anomaly. It differs from classical bronchopulmonary sequestration in that the involver lung retains a normal connection to the bronchial tree, although some place this entity exists within the broad framework of pulmonary sequestration. We experienced a case of a woman who presented with a nodular lesion on a chest X-ray. Contrast-enhanced CT diagnosed her as having an anomalous systemic arterial supply to the normal basal segments of the left lower lobe. This case is reported with a brief literature review.

For those with allergy, vaccination with a specific allergen has often been used as a major therapeutic measure. However, the universal application of this technique in clinics have been restricted due to its low success rates and the risk of active systemic anaphylactic shock (ASAS). In this regard, we constructed a fusion protein (OVA-DT), ovalbumin (OVA) fused with diphtheria toxin protein (DT), which may exert a specific cytotoxicity to cells bearing OVA-specific IgE. Its therapeutic effect was evaluated in mice (BALB/c) sensitized with OVA (Os-mice). OVA challenges to the OVA-sensitized mice (Os-mice) caused ASAS to death within 30 min, but OVA-DT treatment afforded mice complete protection. When OVA-DT was treated to the Os-mice, none showed the signs of ASAS when re-challenged 48 h after the treatment. OVA-DT itself was not found to be toxic or allergenic in normal mice. The effect of OVA-DT on the biological functions of mast cells was also studied. Binding of OVA-DT to OVA-specific IgE bearing mast cells and the inhibition of histamine release from these cells were observed. In addition, OVA-DT treatment inhibited the proliferation of OVA-specific B cells in mice. In Os-mice treated with OVA-DT, levels of anti-OVA IgG2a in serum and the production of IFN-gamma by splenic lymphocytes were found to increase, but the production of IL-4 by these cells decreased. Re-direction of cytokine profiles from OVA-specific Th2 to OVA-specific Thl is suggested. These results indicate that OVA-DT can protect Os-mice from ASAS due to OVA challenge, because it inactivates OVA-specific IgE-expressing cells, including mast cells and B cells.

PURPOSE: Prognosis of papillary thyroid carcinoma (PTC) is very favorable, but PTC frequently invade adjacent soft tissue and metastases to cervical lymph node. We evaluated the pattern of cervical neck lymph node metastasis in PTC according to tumor size. METHODS: From August 2005 to January 2009, 353 patients were underwent surgery for PTC. Among these patients, total thyroidectomy with cervical neck lymph node dissection were done in 266 patients. We subdivided patients into four groups according to size and compared the clinicopathologic characters between groups. And we confirmed the factors affecting central neck node metastasis. RESULTS: The mean age of patients of diagnosis was 49.1 years and female to male ratio was 5.8:1. Cervical lymph node metastasis were in 47.0% of the total cases. Cervical lymph node metastases and invasion to adjacent structure increased with tumor size. But, there were no significant differences in tumor size, invasion to adjacent structure, multifocality or bilaterality according to cervical lymph node metastasis. Early diagnostic age and sexuality were significantly related to cervical lymph node metastasis of PTC. CONCLUSION: PTC showed the aggressiveness with increasing tumor size. Tumor size was not related to cervical lymph node metastasis. These findings suggest that tumor size can help treat PTC, can`t be used by prediction factor of cervical lymph node metastasis.

BACKGROUND: Varenicline is now very useful medication for cessation; however, there is only little result of researches with varenicline for cessation of hospitalized patients. This research attempted to analyze the cessation effect of medication and compliance of hospitalized patients. METHODS: This research included data for 52 patients who were prescribed varenicline among 280 patients who were consulted for cessation during their admission period. This research checked whether smoking was stopped or not after six months and analyzed their compliance, the factors for succeeding in smoking cessation. RESULTS: One hundred and ninety hospitalized patients participated in smoking cessation counseling among 280 patients who included consultation from their admission departments. And varenicline was prescribed for only 80 patients after counseling. Nineteen smokers were successful in smoking cessation among 52 final participants representing the rating of success of 36.5%. The linkage between compliance of varenicline and rate of smoking successful has no statistical significance. The factors for succeeding in smoking of hospitalized patients are admission departments, diseases, and economic states. CONCLUSION: Smoking cessation program has low inpatient compliance. Cooperation of each departments is very important for better compliance. Success rate of cessation was relatively high (36.5%). Cessation attempt during hospitalization is very effective strategy.
