Purpose : Acute measles encephalitis(ME) is characterized by an abrupt onset of fever and obtundation, frequently accompanied by seizures and multifocal neurological signs. The aim of this study was to clarify the clinical manifestation, progression and the brain SPECT patterns in patients with acute ME. Methods : This study included 11 children with acute ME admitted to Chonbuk National University Hospital. Ten patients received a first dose of measles vaccine, one patient did not receive a first dose, and no patients received a second dose. ME was diagnosed based on characteristic clinical pictures, measles antibodies by ELISA and abnormal CSF findings. Brain MRI and brain SPECT were performed in 11 patients with acute ME. Results : There were four males and seven females whose ages at onset ranged between 18 months and 14 years(mean : 10.5 years). The main clinical neurologic pictures were loss of consciousness( 10) and seizure(five). The titer of IgG and IgM antimeasles antibodies in serum were positive in 10 patients. In CSF, nine patients had IgG antibodies and one patient had IgM antibodies. The concentration of protein(mean : $124{\pm}60mg/dL$) and WBC counts(mean : $158{\pm}157/{\mu}L$) in CSF were elevated in all patients. In electroencephalographic examination, nine patients showed increased slow waves. Seven of 11 patients(63.6%) revealed high signal intensity on the brain MRI. In contrast, all patients showed hypoperfusion in brain SPECT examination. According to brain SPECT, the perfusion deficits were frequently observed in the frontal lobe(nine), temporal (nine), parietal(eight) and thalamus(eight). Conclusion : Brain SPECT is more sensitive than MRI for the evaluation of brain damage in early stages of acute ME.

Purpose : To determine the differences in clinical characteristics, blood chemistry and coronary artery complications between patients with Kawasaki disease who received intravenous immunoglobulin (IVIG) within the fourth day of illness and after the fifth day of illness. Methods : A retrospective chart review was conducted of all children with Kawasaki disease who were admitted to Ewha Mokdong Hospital between January 2001 and June 2002. The early treatment group received IVIG within the fourth day of illness(n=34) and the control group received IVIG after the fifth day of illness(n=53). Clinical manifestations, fever duration, hospitalization days, CBC, blood chemistry and coronary artery complications were compared between two groups. Results : No demographic differences were noted between the two groups(P>0.05). Total duration of fever was significantly shorter in the early treatment group than the control group($4.8{\pm}2.5days$ vs $7.4{\pm}3.0days$, P<0.05), but there were no differences in fever duration after IVIG treatment and hospitalization days between two groups(P>0.05). No significant differences were noted in the level of hemoglobin, WBC, ESR, CRP, AST, ALT and albumin between two groups(P>0.05). No significant differences in the incidence of IVIG retreatment were noted between the two groups(11.8% vs 5.7%, P>0.05). No significant differences in the incidence of coronary artery complications were noted between the two groups(11.7% vs 18.9%, P>0.05). No significant differences in the recurrence rate were noted between the two groups(3% vs 2%, P>0.05). Conclusion : Early IVIG treatment in patients with Kawasaki disease reduces the total fever duration. Coronary artery complications were not increased in patients with early IVIG treatment.

Purpose : Bronchial hyperresponsiveness(BHR) in asthma is thought to be a consequence of underlying airway inflammation. But the mechanism responsible for persistent BHR in adolescents with long-term asthma remission is poorly understood. The aim of this study was to examine whether BHR in adolescents with asthma remission is associated with peripheral blood eosinophilia and/or increased serum levels of eosinophil cationic protein(ECP). Methods : We studied 35 adolescents with long-term asthma remission(neither symptoms nor medication during the previous two years) who have persistent BHR(remission group) and 35 adolescents with symptomatic asthma(symptomatic group) who were matched for methacholine provocative concentration producing a 20% fall in $FEV_1(PC_{20})$ with subjects in the remission group. The peripheral blood eosinophil counts and serum ECP concentrations were compared between these two groups. Correlations between $PC_{20}$ and peripheral blood eosinophil counts or serum ECP concentrations were assessed in these two groups. Results : Peripheral blood eosinophil counts and serum ECP concentrations were significantly lower in the remission group than in the symptomatic group($273{\pm}108$ vs. $365{\pm}178/{\mu}L$; $16.3{\pm}9.4$ vs. $26.5{\pm}15.1{\mu}g/L$, both, P<0.05). $PC_{20}$ was correlated with peripheral blood eosinophil counts and serum ECP concentrations in the symptomatic group(r=-0.385, P=0.022; r=-0.439, P=0.008), but not in the remission group(r=-0.292, P=0.089; r=-0.243, P=0.159). Conclusion : BHR in adolescents with long-term asthma remission is not associated with peripheral blood eosinophilia or an increase in serum ECP concentration, which suggests that BHR in this clinical setting may not be attributed to airway eosinophilic inflammation. Further studies including direct assessment of airway inflammation are needed to confirm this conclusion.

The stone Buddhas and Shrine of Unjusa temple (Korea Treasure No. 797) in Hwasun formed in Koryo Dynasty are unique style which the Buddha faces each other the back parts of south and north within the stone Shrine. The stone Buddhas and Shrine are highly evaluated in historical, artistic and academic respects. But, the stone properties have been exposed in the open system various aspects of degradations weathered for a long time without specific protective facilities. The rock materials of the stone Buddhas and Shrine are about 47 blocks, and total press load is about 56.6 metric ton. The host rocks composed mainly of white grey hyaline lithic tuff and rhyolitic tuff breccia. In addition, biotite granite used as part during the restoration works. The chemical index of alteration for host tuffaceous rocks and the replacement granites range from 52.1 to 59.4 and 50.0 to 51.0, respectively. Weathering types for the stone Buddhas and Shrine were largely divided with physical, chemical and biological weathering to make a synthetic deterioration map according to aspects of damage, and estimate share as compared with surface area. Whole deterioration degrees are represented that physical weathering appeared exfoliation. Chemical weathering is black coloration and biological weathering of grey lichen, which show each lighly deterioration degrees. According to deterioration degree by direction of stone Buddhas and Shrine, physical weathering mostly appeared by 39.1% on the sorthern part, and chemical weathering is 61.2% high share on the western part. Biological weathering showed 38.3% the largest distribution on the southern part. Therefore, it is necessary to try hardening for the parts with serious cracks or exfoliations, remove secondary contaminants and organisms through regular cleaning. Also necessary to make a plan to remove moisture of the ground which causes weathering, and estimate that need established and scientific processing through clinical demonstration of conservation plan that chooses suitable treatment.

The rock properties of the West pagoda in the Gameunsaji temple site are composed mainly of dark grey porphyritic granodiorite with medium grained equigranular texture and developed with small numerous dioritic xenoliths. These xenoliths occurred with small holes due to different weathering processes. As a weathering results, the rock properties of this pagoda occur wholly softened to physical hardness because of a complex result of petrological, meteorological and biological causes. Southeastern part of the pagoda deteriorated seriously that the surface of rock blocks showed partially exfoliations, fractures, open cavities in course of granular decomposition of minerals, sea water spray and crystallization of salt from the eastern coast. The Joint between blocks has small or large fracture cross each other, contaminated and corrupted for inserting with concrete, cement mortar, rock fragments and iron plates, and partially accelerated coloration and fractures. There are serious contamination materials of algae, fungus, lichen and bryophytes on the margin and the surface on the roof stone of the pagoda, so it'll require conservation treatment biochemically for releasing vegetation inhabiting on the surface and the discontinuous plane of the blocks because of adding the weathering activity of stones and growing weeds naturally by soil processing on the fissure zone. Consisting rock for the conservation and restoration of the pagoda would be careful choice of new rock properties and epoxy to reinforce for the deterioration surfaces. For the attenuation of secondary contamination and surface humidity, the possible conservation treatments are needed.

Purpose : The clinical characteristics of renovascular hypertension (RVHT) in children were analyzed. Methods : Medical records of 16 children diagnosed as RVHT on the basis of angiography during Jan. '86 to Jun. 94 in our hospital were reviewed retrospectively. Results : The mean age at the onset was 8.5 yrs and the sex ratio(M:F) was 7:9. The causes of RVHT were Takayasu arteritis in 6, Moyamoya disease in 5, and fibromuscular dysplasia in 3 patients. Abdominal bruit was noted in 6 patients (38%). Peripheral renin activity was raised in all tested patients. Bilateral renal arterial involvemnent was found in 9 patients (56%). Captopril renal scans showed good correlation with angiographic findings. Five patients were treated with antihypertensives only, and blood pressure was controlled completely in 2 and incompletely in 3. Percutaneous transluminal angioplasty was performed in 10 patients with 50% of success rate. However, hypertension was recurred due to restenosis or accompaning aortic stenosis in 3 patients. Surgical treatment was performed in 4 patients, and the blood pressure was controlled partially in 1 and poorly in the remaining 3. Conclusions : Takayasu arteritis, Moyamoya disease and fibromuscular dysplasia are the major causes of childhood RVHT in our country. The diagnosis of RVHT in children should be based on a set of tests individually selected for case by case. For the low curability of the current treatment modalities available, RVHT in children should not be regarded as 'curable' so far. We expect, however, that the outcome will be improved by more extensive application of the newly developed surgical technique.

One hundred forty-four patients underwent operation for coarctation of the aorta at Seoul National University Children's Hospital between June 1986 and Decembsr 1995. Age ranged 0.1 to 191 months. Of these 78.5%(113) were infants. We classified the patients in terms of the anatomic location of coarctatiln and the associatCd anomalies(I[401= primary coarctation, 11(741=isthmic hypoplasia, lIIf30)=tubular hypoplasia involving transverse arch, Ar63 =with ventricular septal defect, B(28)=with other major cardiac defects). Subcalvian flap coarctoplasty(60), resection & anastomosis(44), extended aortoplasty(26), and onlay patch(14) were used as surgical methods. Overall operative mortality was 16.0(23/144)%. The hospital mortality was signific'antly higher in patheints with type 111, subtype B, younger age(under 3 months), extended aortoplasty(p(0.01). However, one-stage total repair in patients with subtype A or B were not found to be a predictor of hospital death. Restenosis had occured in 18 patients among 121 survivals(14. 9%). The mean follow-up period was 29.1 $\pm$28.8(0~129.2) months. Preoperative, immediate postoperative(within 3 months after operation) and postoperative(later than 6 months after operation) echocardiographic data on the dimensions of ascending aorta(AA), transverse arch(TA), an4 aortic isthmus(Al) were available in 77 patients(I=20, ll=42, 111= 15). Preoperative and postoperative aortic isthmus(All) and tra sverse arch indices(TAI), defined as TAIAA & AIIAA respectively, were compared. Immediate postoperative All in type 1, II and TAI in type 111 were significantly smaller in stenotic than non-stenotic group suggesting incomplete relieves of stenotic segment Younger age, subclavian coarctoplasty in patient under 3 months of age were round to be the risk factors for restenosis in this series. In conclusion, We found that aortic arch index and transverse arch index can be a useful tool to figure out the anatomic and clinical characteristics of the patients with aortic coarctation, and that anatomy, associated anomalies, age, and surgical methods may influence the surgical outcome of the coarctation repair.

Background: The treatment results of the advanced lung carcinoma is not satisfactory with the present therapeutic modalities: surgical resection, anti-cancer chemotherapy, and radiotherapy or combination therapy. To predict the prognosis of the non-small-cell lung carcinoma, TNM classification has been was as the basic categorization; however, it has been not satisfactory. It is necessary to consider the causes and the prognosis of the lung carcinoma from another points of view rather the conventional methods. We intended to find out the relationship between the major apoptotic factor, p53 gene and the prognosis of the patient with lung carcinoma. Material and Method: Three hundreds and fifty-nine patients with lung carcinoma who underwent surgery were analysed. We observed p53 protein accumulated in the cellular nuclei. The p53 protein was detected by immuno-histo-chemical method. We collected information of the patient retrospectively. Result: p53 protein densities were observed in 40% in average as a whole. The protein density was 44 percent in man, 25 percent in woman, 49 percent in the squamous cell carcinoma, and 38 percent in the adenocarcinoma. There were significant correlations between the p53 protein density and the mortality in the squamous cell carcinoma (p=0.025), follow-up duration in TNM stage I group (p=0.010), and follow-up duration in the lobectomy patient group (p=0.043), and tumor cell differentiation (p=0.009). p53 protein densities were significantly different between the lobectomy and the pneumonectomy group (p=0.044). Conclusion: The authors found that p53 protein had some correlations with the prognosis of the lung cancer partially in some factors. We suggest the p53 protein density could be used as a marker of prognosis in the non-small-cell lung carcinoma.

This research examined the effects of Compositae extract on the inhibition of proliferation and apoptosis in human breast and human gastric cancer cells. Compositae extracts which is used in the experiment are Taraxacum coreanum (TC), Youngia sonchifolia (YS) and Ixeris dentata (ID). The proliferation of SK-BR-3, MDA-MB-231 and AGS cells were investigated by MTT assay. ID and YS extracts inhibited proliferation of SK-BR-3, MDA-MB-231 and AGS cells in a dose-dependent manner, but TC have barely affected. In addition, the most effective extract was ID. To assess the apoptosis of ID extract, the nuclei of human cancer cells were stained with DAPI solution respectively. Chromatin condensation, indicated apoptosis, was increased in a dose-dependent manner. We investigated change of ID extract-induced apoptosis proteins on human cancer cells by western blot analysis. The level of Bcl-2 decreased, whereas the level of Bax, cleaved-PARP increased in dose-dependent manner compared with non-treatment. Also Bax/Bcl-2 ratio, which is used in clinical indicator of apoptosis, was increased at ID extract treatment group compared with non-treatment. Moreover the Bax/Bcl-2 ratio of MDA-MB-231 cell was significantly increased as against SK-BR-3, AGS cells. These results indicated that ID extract have anti-proliferation effect better than YS or TC, and induced apoptosis in human breast cancer MDA-MB-231 cell better than human breast cancer SK-BR-3 cell, human gastric cancer. Even if further research is needed, ID can be developed as a chemopreventive or therapeutic agent of breast cancer.

This study was undertaken to determine the normal appearance of the postpartum uterine involution. Postpartum changes in uterine shape, architecture, echogenicity and diameter were monitored with ultrasonography in 8 Cocker spaniel bitches. The excretory period of vaginal discharges in 8 normal bitches of uterine involution was finished completely at 23.20$\pm$2.77 days (Mean$\pm$SD) postpartum. The short axis shape of the uterus was varied from polygonal to circular. This lasted until 1600$\pm$2.12 days Postpartum, during which time the short axis uterine shape gradually changed to circular. Also, the long axis shape of the uterus was created a beaded appearance of the horns until 25.60$\pm$2.51 days postpartum. The uterine diameter was decreased not only in the placental sites from 24.20$\pm$2.06mm at 1 day to 13.18$\pm$0.84mm at 7 days postpartum, but also in the interplacental sites 14.26$\pm$2.22mm at 1 day, 9.81$\pm$0.7mm at 7 days postpartum. There was a general trend of decreasing uterine diameter, which occurred more rapidly at the placental sites. In conclusion, normal postpartum uterine involution in Cocker spainel bitches appeared to be completed around 68 days postpartum by gross findings such as vaginal discharges, and by ultrasongraphic findings, uterine shape and echogenicity.
