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: Cicletanine bydrochloride is a newly developed anti-hypertensive agent. The presence of a furopyridine group characterizes its uncommon chemical structure as an antihypertensive molecule. This clinical trial was performed to confirm the efficacy and safety of cicletanine for the treatment of hypertension as a monotherapy. METHODS: In order to investigate the efficacy and safety of oral cicletanine, a now class of antihypertensive durgs, the furopyridines, on essential hypertension, a single daily dose of 50mg to 100mg cicletanine was administered in 46 hypertensive patients with diastolic blood pressure in the range of 95mmHg-115mmHg. The patients were asked to cut off other anti hypertensive agents for 10 weeks prior to this clinical trial. Blood pressure and heart rate were measured every 4 weeks. The complete blood count, blood chemistry done by SMA-12, serum electrolytes and urinalysis were performed at the 12th week of therapy. RESULTS: 1) Baseline blood pressures after 2 weeks of placebo at sitting and standing positions were 158.7+/-16.1/102.9+/-6.2 and 148.7+/-14.5/102.7+/-6.7mmHg, respectively. The overall slope which represents the tendency of blood pressure decline over the treatment period with cicletanine for all the patients in each position are as follows ; -0.726(SE : 0.150) for sitting systolic blood pressure(BP), -0.390(SE : 0.080) for sitting diastolic BP, -0.214(SE : 0.183) for standing systolic BP and -0.341(SE : 0.139) for standing diastolic BP. 2) The slope of sitting systolic BP line in cicletanine 100mg treated group was significantly stiffer than that of cicletanine 50mg treated group(-0.445 vs -1.021, p=0.0336). 3) There were no significant interval changes in heart rate over the treatment period. 4) There were no significant interval changes in blood chemistry, electrolytes, hematologic findings and urinalysis over the treatment period. 5) Several side effects were observed in six patients(epigastric discomfort in 4, easy fatigue and insomnia in one patient, respectively). CONCLUSION: Treatment with cicletanine was well-tolerated and the incidence of side effects was relatively low. Because of its unique anti-hypertensive mechanism and moderated antihypertensive effects, cicletanine may be well suited in the treatment of hypertension combined with other classes of antihypertensive agents.
