OBJECTIVES: Hypertension provokes left ventricular diastolic dysfunction due to decreased elasticity of the ventricular myocardium at first. It has been proposed that the Doppler echocardiography might provide information concerning diastole because of its ability to measure the blood flow velocities across the mitral valve noninvasively. But Doppler mitral velocity may be "normalized" in hypertensive patients in different conditions. The purpose of this study is to evaluate diastolic function in hypertensive hearts using Doppler echocardiography of the pulmonary venous flow in conjunction with mitral flow velocity pattern. METHODS: We measured the mitral flow velocity curves and the pulmonary flow velocity curves in fifty hypertensive patients(mean age : 56.3+/-10.0, man : 19, woman : 31) nad forty healthy adults(mean age : 51.6+/-12.5, man : 14, woman : 26) from March 1995 to December 1995 by using the SONO 1000 of Hewlett Packerd. RESULTS: 1) The mitral flow velocity pattern in 50 hypertensive patients was characterized by the decrease in the peak early diastolic filling velocity(E : 0.59+/-0.12m/sec) and the ratio of E to peak filling velocity(A : 1.00+/-0.46m/sec). Isovolumetric relaxation time and deceleration time were 127.2+/-33.3msec, 258.9+/-40.9msec respectively. They were longer than normotensive patients(P < 0.05). 2) The pulmonary venous flow velocity pattern in hypertensive patients was characterized by the decreased peak diastolic forward velocity(D : 33.7+/-9.8cm/sec) and the ratio of peak systolic forward velocity(S) to D(S/D : 1.60+/-0.5)(P < 0.05). 3) There was no relation between the flow velocity integral parameters and the peak flow velocity parameters of pulmonary venous flow pattern in hypertensive patients. 4) The dofference in the pulmonary venous duration and the mitral A wave duration at atrial contraction (DA-DR) was 20.9+/-29.4 msec in hypertensive patients. DA-DR in normatensive patients was 24.3+/-32.9msec. DA-DR was not significant in hypertensive patients compared with that of the healthy subjects (P < 0.05) CONCLUSION: Analysis of pulmonary venous flow velocity pattern in conjunction with mitral flow velocity pattern in hypertensive patients provides more accurate assessment of left ventricular diastolic function.

Clinical observation was performed on 23 children with Guillain-Barre syndrome which were hospitalized at the Pediatric ward of Han Yang University Hospital, from July 1975 through May 1991.@ES The results were as follows: 1) The ratio of male patient to female was 2.8:1 and 47.8% of total GBS patients were between the ages 1 to 5 years. 2) The highest seasonal incidence of GBS was seen in summer and there was no significant variation of GBS annually.3) Preceding illness of GBS was found in 60% of the total patients, and upper respiratory infection was the most common (65%). 4) Muscular paralysis or weakness in extremities was the most common chief complaints on admission, and repiratory difficulty, vomiting, diarrhea, swallowing difficulty and myalgia were followed. 5) The sites of paralysis on admission were upper and lower extremities in 14 GBS patients (60.8%), lower extremities in 7 GBS patints (34.8%) and respiratory muscle in 4 GBS patints (17.3%), respectively. 6) The protein content of cerebrospinal fluid was elevated in 18 GBS patients of total (78.3%) on admission and remnant 5 GBS patients showed increased protein later. 7) There was a tendency that recovery time in 5 GBS patients with muscular fibrillation on E.M.G. was longer than in 4 GBS patients without muscular fibrillation. We thought further studies on critical evaluation and better treatment for GBS were needed.

Due to recent upsurge in international marriages, the socio-cultural adaptation, the reinforcement of family stability, and the social integration support of marriage-based immigrant family have been the major social issues. This paper tries to show the current status of marriage-based immigrants and their children nation-wide. Specifically, it analyzes the statistical trends in international marriages, traits of marriage-based immigrants and their children, their attitudes towards child raising and education, and presents policy measures to enhance their life quality.

The aim of this study was to determine the photocatalytic effect of doped-TiO 2 nanoparticles (NPs) on teeth bleaching with an aid of 3% H2O2 and laser irradiation. For the study, Mo-N-TiO2 NPs were prepared. The characteristics of the prepared NPs, NPs morphology and light absorbance, were evaluated. Photocatalytic reactions of NPs were tested using 10 ppm methylene blue (MB) solution. Extracted teeth were pasted using carbomer gel for color differences measurements. Mo-N-TiO2 NPs have close to round shape with some tens nm size. Their absorbance was higher and longer than that of TiO 2 NPs. For MB solution, Mo-N-TiO2 with 3% H2O2 condition showed much decrease in absorbance after laser irradiation for 20 min. Also, regardless of wavelength, Mo-N-TiO2 NPs produced much greater color difference (whitening) on teeth after 3 h than that by 15% H2O2 .

Gastric cancer is the most common gastrointestinal malignancy in Korea. Identification and evaluation ofgastric mass lesions and regional-distant metastases by abdominal CT scan are important for the treatment planningand prognostic implications of gastric cancer patients. Author reviewed CT scan are important for the treatemntplaning and prognostic implications of gastric cancer patients. Author reviewed CT scan of 61 cases of pathologyproven gastric cancer, retrospectively, for recent 20 months from July 1983 to Feb. 1985 at department ofradiology, Korea University, Hae Wha Hospital. The results were as follows: 1. There were 50 cases of advanced adenocarcinoma, 8 cases of early gastric cancer, 2 cases of leiomyosarcoma, and 1 case of lymphoma in total 61cases. 2. The sex ratio of male to female was 2:1. Age distribution was from 24 to 75 year old and peak incidencewas in 6th decade. 3. The most frequent site of involvement with gastric cancer was gastric antrum in 51%. 4. 48of the 50 patients with advanced gastric adenocarcinoma(96%) had a wall thickness greater than 1 cm, and all of 8cases of early gastric cancer had a wall thickness less than 1 cm. Regional lymph node tumor infiltration wasfound in 100% of gastric wall thickness greater than 2.0cm, in 64% of cases of 1.5 to 2.0cm, in 50% of cases of1.9 to 1.5cm, and 12.5% of cases of less than 1.0cm. 5. In a comparison of enlargement of reginal lymph node by CTscan to tumor infiltration of regional lymph node by histology, senitivity was 52%, specificity was 87%, and reliability was 66%. 6. The structures involved by distant metastases of these cases were the retroperitoneallymph node in 15, liver in 8, and pancrease in 3. 7. The diagnostic accuracy of CT staging was considered about68% by correlation of the surgical and histological findings. 8. The CT scan is one of the accurate and simpletool for evaluation of size, shape, extent, as well as distant metastases in the cases of gastric malignancies.
