Surveys about attitudes towards those with epilepsy have been performed since 1949, in order to
understand the social stigma toward epilepsy. This review aims to demonstrate the variation in public
attitudes towards epilepsy and its associated factors, with a critical review of the methodology used
to examine attitudes towards epilepsy. There was marked variation of attitudes between Western and
non-Western populations, and these attitudes were positively correlated with the standard of living.
Besides the general public, studies were also performed within specifi c groups, particularly teachers
and students. However absence of a standardized questionnaire makes direct comparison diffi cult. A
few quantitative methods were developed but these were limited by cultural variations and thus lack
of global acceptance. Short-term intervention studies demonstrate an improvement of attitude with
knowledge. Nonetheless, the cultural and social reasons underlying the attitudes, and how this affects
the life of people with epilepsy, are understudied. Therefore, surveys on attitudes should continue to be
carried out, particularly in populations prone to have negative attitudes with emphasis on underlying
reasons, and such progress should be monitored longitudinally. Attitudes of people such as parents,
teachers, school counselors, health care professionals, and employers, which have a direct impact on
people with epilepsy, should be more extensively studied.

PURPOSE: The purpose of this study was to determine whether Fas-L expression is associated with increased apoptotic induction of tumor-infiltrating lymphocytes (TIL) in human gastric carcinomas. MATERIALS AND METHODS: The author analysed 38 cases of early gastric carcinoma (EGC) and 61 cases of advanced gastric carcinoma (AGC) who received gastric resection, in whom the number of diffuse type was 38 cases and the number of intestinal type was 61 cases. The author used immunohistochemical staining for Fas, Fas-L and CD45, and TUNEL in situ apoptosis detection kit. TIL were detected by CD45 and apoptosis of TIL were detected by CD45 expression and TUNEL positivity on serial histologic sections. RESULTS: Fas-L was localized to neoplastic cells in 61% (23/38) of EGC group and 66% (40/61) of AGC group. The extent of Fas-L expression was variable, with both Fas-L positive and negative neoplastic region occuring within tumors. TIL adjacent to Fas-L expressing tumor region were decreased in number and TIL adjacent to FasL-negative tumor region were increased in number; apoptotic induction of TIL showed just the opposite pattern (p<0.05). Fas expression was found essentially homogeneously throughout the tumor mass independent of tumor stage. Fas expression showed 64% (39/61) of intestinal type and 68% (26/38) of diffuse type. Labeling indices for tumoral apoptosis in EGC and AGC were 6.72% and 7.13%, respectively and this difference was statistically insignificant. Co-expression of Fas-L and Fas, which occurred over large areas of the tumors, did not result in an enhanced rate of tumor cell apoptosis. In addition, factors such as tumor stage and other prognostic factors were not concerned in Fas and Fas-L expression, number of TIL and apoptotic induction. CONCLUSION: These findings suggest Fas-mediated apoptotic depletion of TIL in response to Fas-L expression by stomach cancers, and provide the evidence to support the Fas counterattack as a mechanism of immune escape in gastric cancer. In addition, gastric carcinoma cells of the intestinal and diffuse type did not differ in their expression of the apoptotic receptor Fas.

3.Cyclic Exotropia: One Case of Clinical Report.
Journal of the Korean Ophthalmological Society 1999;40(12):3536-3539
Cyclic strabismus is now well recognized, but remains a rare entity. This heterotropia represents an interesting ocular motility problem in which the ocular deviation is present on a rhythmic basis, usually a 48 hour cycle. On the strabismic day, constant heterotropia is large and associated with suppression and no diplopia. On the nonstrabismic day, no deviation or only a small heterophoria is present with good binocular function. Most of these strabismus were presented with esotropia, but in our case, the pattern of deviation is cyclic exotropia. This is a very rare and unique feature.

4.Quantitative cine-left ventriculography
Journal of the Korean Radiological Society 1981;17(3):484-491
The volumetry by cineangiocardiography is known to have the most diagnostic and prognostic value in theevalutaion of various valvular heart diseases and ischemic heart diseases. Athough many authors favor thearea-length method for the voulmetry of left ventricle, 45degrees RAO projection seems to be more simple,inexpensive and acurate technique, considering the positional relationship of cardiac valves and obliquity of thelong axis of left ventricle within the chest cage. Authors present the anatomical, geometrical and radiologicalbasis for the superiority of 45degrees RAO projection by analyzing 20 normal heart specimen and 115cineangiocardiograms of valvular heart disease, and the results as follows; 1. Blood flow and motility of themitral and aortic valves can be more clearly demonstrated by 45degrees RAO projection than by AP view. 2. The longdiameter of left ventricular silhouette made 45degrees RAO projection reflects 90% or more of real diameter. 3. InRAO 45degrees position, patient's left nipple is optimal and convenient level for the ruler offering accuratemagnification coefficient of left ventricle. 4. Ejection fration after the extrasystole is exaggerated regardlessof the left ventricular function, so it is desirable to exclude the 2 or 3 beats after extrasystole.

Accurate reproduction of intraoral tissue is essential in the fabrication of fixed prosthesis. This selection of impression material and method is very important. In this study, vinyl polysiloxane type impression material Panasil was used. Three impression methods ; one-step technique, individual tray technique, and individual tooth tray technique using the vinyl polysiloxane type bite registration material Futar Occlusion, were used to take horizontal and vertical impression. Improved stone models were fabricated. The amount of occlusal surface discrepaneies, interabutment distance discrepancies, amount of marginal defect were evaluated with the X-PLAN360d and photoscanning. The results were as follows. 1. There was no significant difference in occlusal surface according to the directions and techniques of impression taking. 2. There was no significant difference in interabutment distance discrepancies according to the directions and techniques of impression taking 3. There was no significant difference in marginal discrepancies according to the direction of impression taking but there was significant difference between one-step technique and individual tray technique, individual tooth tray technique (P<0.05). Taken together, these results suggest that individual tray technique and individual tooth tray technique are more accurate for impression taking than one-step technique.

PURPOSE: This study was performed to evaluate the features of pulmonary lobes and fissure in Korean and to compare with the previous results. MATERIALS AND METHODS: HRCT scans of 82 healthy Korean adults, performed with scan interval of 1.5/2.0 cm, were reviewed. RESULTS: Located mostly on inner aspect, incidences of incomplete oblique and horizontal fissure were 60% (Rt 48%, Lt 39%) and 51% respectively, lower than 70--80% and 60--75% of western studies. Superolateral oblique fissure, inferior accessory fissure, left horizontal fissure and other accessory fissure were shown in 1%, 13%, 7%, and 8% respectively. Lower lobe upper part faced laterally (Rt 91%, Lt 82%) while lower part faced medially (Rt 61%, Lt 79%). Right middle lobe ws highest posteromedially (49%) and was convex (97%). CONCLUSION: Features of pulmonary lobes and fissure in Korean were similar to the results of previous reports but with lower incidence of variation.

Dental porcelain should have adequate strength and similar esthetics as natural teeth. Recently esthetics has become a high priority in clinical dentistry. Thus the evaluation of color stability of dental porcelain has become an important part in dental research. The purpose of this study was to evaluate the difference in color stability of 3 types of porcelain (Vintage, VMK 95, CERAMCO II). The porcelain were divided into groups by 2 types of treatment (Glazing or non-glazing and thermocycling or non-thermocycling). The porcelain wee dyed with methylene blue and distilled water, and then the color stability was evaluated with a spectrophotometer. The results were as follow ; 1. The color change of porcelain increased in the order of VMK 95, Vintage, CERAMCO II. But there was no significant difference. 2. The color change decreased in the glazing group compared to the non-glazing group(p<0.05). 3. The color change increased after thermocycling But there was no significant difference. 4. The color change according to dye method was significantly larger with methylene blue copared to distilled water(P<0.05).

With development of immunochemical methods for anlysis of serum proteins, quantitative determination of serum immunoglobulin levels and purification of them have been made possible in recent years. There are numerous reports about immunoglobulin levels in various diseases. A search of the literature reveals very few reports of quantitative immunoglobulin determinations in allergic dermatoses. The present study was conducted to find quantitative changes of serum immunoglobulins in a few allergic dermatoses. To quantify the IgG, IgA and IgM, one hundred and two sera were analysed form 30 normal control group, 30 contact dermatitis patients, 12 stopic dermatitis patients and 30 urticaria patients by modified Oudin's capillary tube method. The results are as follows. 1.In contact dermatitis the IgG was significantly increased to compare with control group(p<0.01) 2.In atopic dermatitis the IgA was significantly increased to compare with control group(p<0.01) 3.In urticaria the IgG was increased (p<0.05) 4.The IgM has no differences between allergic dermatoses and control group.

The color change of maxillofacial silicone has been attributed to certain environmental factors such as exposure to the UV component of natural sunlight, wetting and drying of the elastomer, and surface abrasion resulting from the application and removal of cosmetics. The purpose of this study was to evaluate the color change of maxillofacial silicone (Silastic MDX4-4210) according to type of pigment (cadmium yellow, titanium white, cosmetic red), and UV absorber application method after 200, 400, and 600 hours of 350nm UV light irradiation. The results were as follows. 1. According to type of pigments, after 200 hours cosmetic red showed significantly larger color change than cadmium yellow and titanium white, and after 400 and 600 hours color change significantly decreased in the order of cosmetic red, cadmium yellow, and titanium white (p<0.05). 2. In the cadmium yellow group, after 200 hours, the non-treatment group showed significantly larger color change, but after 400 and 600hours, color change significantly decreased in the order of non-treatment, surface application and mixed group (p<0.05). 3. In the titanium white group, there was no significant color change difference between the three groups after 200 and 400 hours, but after 600 hours, the mixed group showed significantly smaller color change than the non-treatment and surface application groups (p<0.05). 4. In the cosmetic red group, there was significant decrease in color change in the order non-treatment, surface application and mixed group (p<0.05). From the results above, the effect of UV light absorber differed according to the type of pigment, but mixing UV light aborber with maxillofacial silicone is thought to give superior resistance against UV light irradiation in the long run.

Breast cancer is one of the leading causes of death attributable to cancer in women. In view of the limitations of conventional predictable factors of the breast cancer, additional second-generation parameters would be valuable in selecting the patients who would be most likely to be beneficial from adjuvant therapy and breast reconstruction. The author investigated the HER2/neu gene amplification and the number of chromosome 17 in 39 cases of paraffin embedded breast cancer tissues, 20 cases without lymph node metastasis and 19 cases with lymph node metastasis, using fluorescent in situ hybridization(FISH) and compared the results with HER2/neu and p 53 protein expression detected by immunohistochemical method. Eleven cases fibroadenoma were used as benign tumor control. Numerical aberrations of chromosome 17 were found in 17 out 39 breast cancer cases (44%)(monosomy in 10 cases, 26%; trisomy in 3 cases, 8%; tetrasomy in 3 cases, 8%; polysomy in 1 case ,3%), and the frequency of each type aberration was not significantly different between the negative and positive groups in lymph node metastasis. Monosomy of chromosome 17 was found in 2 out of 11(12%) fibroadenoma cases. HER2/neu gene amplification was found in 8 out of 39 cases (19%) and other 2 cases revealed HER2/neu gene amplification in lymph node metastatic tumor only, not in original tumor. Fourteen out of 19 cases of breast cancer with lymph metastasis showed HER2/neu protein expression both in original and metastatic tumors. All of the six cases showing HER2/neu gene amplification in original and/or metastatic tumor revealed HER2/neu protein expression. The frequency of HER2/neu gene amplification in the 39 breast cancer cases was not different between metastatic and non-metastatic groups(p= 0.284). However, HER2/neu protein expression was increased significantly in the metastatic group(p=0.028). None of the 11 fibroadenoma cases revealed HER2/neu gene amplification or HER2/ neu protein expression. Nine out of 19 cases of breast cancer with lymph node metastasis showed p 53 protein accumulation in original tumor(47%), but 3 of them revealed p 53 protein accumulation only in original tumor. The frequency of p 53 protein accumulation was not significantly different between metastatic and non-metastatic groups. None of the 11 fibroadenoma cases revealed p 53 protein accumulation. In conclusion, there are no differences between the lymph node metastatic group and non-metastatic groups in numerical aberrations of the chromosome 17 , amplification of the HER2/neu gene expression and accumulation of the p 53 protein in breast cancer. However, the HER2/neu protein expression was increased significantly in lymph node metastatic group, so it could be one of the predictors of the metastasis in breast cancer.
