Magnetic Resonance Imaging(MRI) with 2.0 Tesla superconductive magnet developed by Korea Advanced Institute ofScience was performed in 25 patients with various abdominal diseases and compared with x-ray CT. MRI was obtainedwith spin echo technique using a variety of pulse sequence and various slice orientation including axial, sgittaland coronal section in order to evaluate the diagnostic value, limitation and to determine the optimal pulsesequency in various abdominal diseases. MRI demonstrated the capability of detecting the lesions shown on CT inall cases and also detected one case of diffuse hepatocellular carcinoma which was not seen on CT. MRI showedcapability of differentiation of various liver mass including hepatocellular carcinoma, hemangnioma and simplecyst. MRI showed better anatomical resolution of tumor in retroperitoneum and pelvis, however CT delineatedalimentary tract disease better than MRI did.

The incidence of tracheal stenosis is increased because of the longterm respiratory care with endotracheal intubation and tracheostomy. Present therapeutic modalities for the relief of an tracheal or bronchial stenosis include laser resection, radiotherapy, cryotherapy, bougienation, stent insertion, dilatation with balloon catheter and finally reconstruction surgery. However, reconstruction surgery have some problems in ventilation during anesthetic management. Small sized tube insertion through lesion, high frequency jet ventilation, cardiopulmonary bypass are served to resolve ventilatory problem. We experienced a case of severe tracheal stenosis due to tracheostomy. The stenotic lesion was 2.5 cm above the carina, 3 mm in diameter and length of the stenotic segment was 1 cm. We used bougienation with endotracheal tube replace obturator for the ventilation before the reconstruction surgery and the patient was successfully managed without complications.

To investigate the factors which affecting the cognitive impairment of the 60 or more age group, the authors surveyed for the subjects in some area of Kyungnam Province. 201 studied subjects were tested for cognitive function with mini-mental state examination(MMSE). Information on demographic characteristics and life style has been collected through direct interview. The concentration of Al and Ca of subject's drinking water, which might be related with cognition, was measured by Inductively Coupled Argon Plasma Spectrometer. The main results were summarized as follows. 1. The prevalence rate of cognitive impairment was 18.4% in male and 45.2% in female and this sexual difference was statistically significant(p=0.03). And the uneducated or illiterated showed significantly high prevalence rate of cognitive impairment(p=0.02). 2. In stratified analysis by sex and education year, we can not see significant trend indicating the neurotoxic effects of aluminum and protective effects of calcium to the cognitive function(p>0.05). 3. The correlation between the concentration of aluminum in drinking water and the MMSE score in whole subjects showed weak negative relationship(r=-0.066). But there was no statistical significance(p=0.434).

BACKGROUND: In recent years, the incidence of obesity increased in Koreans. The main cause suggested is the diet style of Korean changed to that of Western. It has been proved that obesity is a risk factor or an aggravating factor of hypertension and diabetes mellitus, cardiovascular disease, etc. Primary physician has been interested in the correlation of blood pressure with relative body weight and aging. The purpose of this study was to focus on the influence of age and relative body weight on blood pressure. METHODS: Subjects were collected from 2,068 adults who had received Adult Health Examination. That subjects were divided according to age, relative body weight and then the relation of blood pressure with age according to relative body weight and relation with relative body weight according to age were investigated. RESULTS: Systolic blood pressure increased significantly according to age in all male and female three weight groups and then increased significantly according to relative body weight in all male and female three age groups except male seventh decade group. Diastolic blood pressure increased significantly according to age in all male and female three weight groups except male obesity group and then increased significantly according to the relative body weight in all male and female three age groups except male and female seventh decade groups. Systolic blood pressure has higher correlation with age than relative body weight and diastolic blood pressure has higher correlation with relative body weight in male. In female, systolic and diastolic blood pressure have higher correlations with age. CONCLUSIONS: It can be suggested that blood pressure increase significantly according to aging process and relative body weight. These two factors have a little different effects to systolic and diastolic blood pressure according to sex. Relative body weight has more effect to diastolic blood pressure than systolic blood pressure in male.
