Comprehensive review of the literature was conducted to determine 1) selected risk factors and its impact that affect pregnancy outcome such as smoking, alcohol consumption, and substance abuse 2) these factors can facilitate future strategies for health promotion and prevention for both pregnant women and fetus. Review of literature were extracted from searching MEDLINE(1966 - Oct. 2000). CINAHL (1982 - Oct. 2000) and the domestic literature. The following factors were identified: 1. The effects of risk behaviors on pregnancy. ${\cdot}$Maternal smoking was associated with the occurrence of premature or LBW delivery, fetal growth retardation, extremities defects, heart defects and sudden infant death syndrome. ${\cdot}$Maternal alcohol consumption was associated with spontaneous abortion, premature or LBW delivery, morphologic/neurologic problems, especially fetal alcohol syndrome. ${\cdot}$Heroin was associated with withdrawal after birth in which were born to heroine addicts for gestational age and lung maturation in animal studies. ${\cdot}$Cocaine was associated with spontaneous abortion, abruptio placenta and a poor response to environmental stimuli. ${\cdot}$So far, the effects of caffeine on pregnancy was controversial, but severe caffeine consumption was associated with premature or LBW delivery, spontaneous abortion, still birth and dystocia. 2. Intervention methods and its effects identified were as follows ${\cdot}$Conducted intervention for smoking, alcohol and drug consumption were single or combined. ${\cdot}$Intervention methods were counseling, phone contact, mailing, use of educational videotape, booklet, support person and alternatives such as nicotine patch. ${\cdot}$The interventions increased the rates of smoking cessation during pregnancy and awareness of the risk of drug consumption, and decreased amount of alcohol consumption. ${\cdot}$The intervention outcome found positive effect on birth weight and length. 3. Our recommendations were as follows ${\cdot}$The personal and social cognition should be enhanced through education and the mass media. ${\cdot}$It's necessary to educate and give information of preconceptional care, planned pregnancy and early prenatal care for optimal pregnancy outcome. ${\cdot}$It's necessary to develop comprehensive assessment tool which is reliable and valid on smoking, alcohol consumption and substance abuse to identify supportive or interventional program.
The author obtained index of red cell volume distribution width(RDW) and other red cell indices in 210 patients of various hematoncologic conditions and 200 healthy control group using, an automated blood analyzer, Coulter Counter Model S-plus II. This study performed to classify various etiologic anemia based on the MCV and RDW, to evaluate availability to the differential diagnosis in korean anemic distoders somewhat different from etiologies of anemias in foreginers. In the most of cases, the increase or decrease of MCV were always combined the pararell changes of MCH and MCHC. But the values of MCV and RDW were not correlated in control group and patient group. So the terms of heterogenous of homogenous anemia were meaningful morphologic classification than hypochromic or normochromic anemia. The heterogenous microcytic anemia contained iron deficiency anemia. In heterogenous normocytic anemia, myelophthisic anemia, acute leukemia were contained. In heterogenous macrocytic anemia, megaloblastic anemia, hemolytic anemia were contained. The homogenous microcytic anemia was observed in anemia of chronic disorders. In homogenous normocytic anemia, acute blood loss, chronic leukemia, multiple myeloma were contained. The aplastic anemia was belonged to homogenous macrocytic anemia. The diagnostic significance of RDW in hemoglobinopathies is most important. But this study was not contained hemoglobinopathies. Instead RDW was very helpful to differential diagnosis of most common anemias, iron deficiency anemia and anemia due to chronic disorders in Korea.
Objective : We determined whether the expression of GRIM-19 is correlated with pathologic types and malignant grades in gliomas, and determined the function of GRIM-19 in human gliomas. Methods : Tumor tissues were isolated and frozen at $-80^{\circ}C$ just after surgery. The tissues consisted of normal brain tissue (4), astrocytomas (2), anaplastic astrocytomas (2), oligodendrogliomas (13), anaplastic oligodendrogliomas (11), and glioblastomas (16). To profile tumor-related genes, we applied RNA differential display using a $Genefishing^{TM}$ DEG kit, and validated the tumor-related genes by reverse transcription polymerase chain reaction (RT-PCR). A human glioblastoma cell line (U343MG-A) was used for the GRIM-19 functional studies. The morphologic and cytoskeletal changes were examined via light and confocal microscopy. The migratory and invasive abilities were investigated by the simple scratch technique and Matrigel assay. The antiproliferative activity was determined by thiazolyl blue Tetrazolium bromide (MTT) assay and FACS analysis. Results : Based on RT-PCR analysis, the expression of GRIM-19 was higher in astrocytic tumors than oligodendroglial tumors. The expression of GRIM-19 was higher in high-grade tumors than low-grade tumors or normal brain tissue; glioblastomas showed the highest expression. After transfection of GRIM-19 into U343MG-A, the morphology of the sense-transfection cells became larger and more spindly. The antisensetransfection cells became smaller and rounder compared with wild type U343MG-A. The MTT assay showed that the sense-transfection cells were more sensitive to the combination of interferon-$\beta$ and retinoic acid than U343MG-A cells or antisense-transfection cells; the antiproliferative activity was related to apoptosis. Conclusion : GRIM-19 may be one of the gene profiles which regulate cell death via apoptosis in human gliomas.

Allergic contact dermatitis is a common skin disease resulting from specific immumologic sensitization to topically applied various allergen. Purpose of this study was to investigate skin morphologic chganges by light microscopic, changes of protein band by SDS-PAGE in the skin treated on the surfactant. Furthermore, lectin histochemistry is used to know the chagnges of the terminal sugar of the glycoconjugate in the skin treated on the surfactant. The results were as follows : The 1 day of treated group was indicated the enlargement of capillary, the 3 days of treated group was showed that the cytoplasm was eosinophlic by the pyknotic of nucleus. The 6 days of treated group was observed hyperkeratinoid, increased of inflammation cells to epithelium. The 9 days of treated group was appeares that serum crust was sheded and formed a acanthosis. But dermis layer was cytoplasmic vaculation and enlargement of intercellular space. The 12 days treated group made up new epidermis layer of seven layer and of observed an decreased in quantity of inflammation cells. The mast cell of degranulated type was increased in treated surfactnat. It was secreating granules hold histamin, serotonin and heparin. Accordingly, protein band of electrophortic phase was observed a sudden changes since 3 days treated group. At observeation of the cell-surface glycoconjugates, LCA, PNA, SBA and WGA lectin positive cells but inducated lectin negative cells in Con-A. Furthermore, PNA and SBA showed stroger positive reaction as treated surfactant group.
Digital Mammography is an efficient imaging technique for the detection and diagnosis of breast pathological disorders. Six mammographic criteria such as number of cluster, number, size, extent and morphologic shape of microcalcification, and presence of mass, were reviewed and correlation with pathologic diagnosis were evaluated. It is very important to find breast cancer early when treatment can reduce deaths from breast cancer and breast incision. In screening breast cancer, mammography is typically used to view the internal organization. Clusterig microcalcifications on mammography represent an important feature of breast mass, especially that of intraductal carcinoma. Because microcalcification has high correlation with breast cancer, a cluster of a microcalcification can be very helpful for the clinical doctor to predict breast cancer. For this study, three steps of quantitative evaluation are proposed : DoG filter, adaptive thresholding, Expectation maximization. Through the proposed algorithm, each cluster in the distribution of microcalcification was able to measure the number calcification and length of cluster also can be used to automatically diagnose breast cancer as indicators of the primary diagnosis.
Cervical dysplasia induces morphologic changes in the cervical epithelium which involve changes in the nuclear/cytoplasmic (N/C) ratio. Since the nucleus is one of the significant scattering sources, the N/C ratio change reflects the degree of circular polarization (DOCP) with the depth of signals. Therefore, we used the polarization-sensitive OCT (PS-OCT) technique to measure the polarization changes caused by scattering. Cervical tissues were obtained from a high-grade squamous intraepithelial lesion (H-SIL) of one woman and from low normal women. We obtained the mean of the DOCP as a function of depth in the cervix and quantified the change ratio of the DOCP using slopes that were determined by linear fits in the epithelium layer. We found that DOCP of H-SIL decayed faster than that of normal tissue because of the higher scattering in H-SIL as expected. This result indicates that the PS-OCT system might be useful in measurements of change ratio of DOCP with depth for screening of cervical dysplasia.
Background: The concept of the ideal morphology for the alveolar bone form is an important element to reconstruct or restore the in maximizing esthetic profile and functional alveolar bone restoration. The purpose of this preliminary study is to evaluate the normal alveolar bone structure to provide the standard reference and guide template for use in diagnosing for implant placement, determining the correct amount of bone augmentation in actual clinical practice and producing prostheses based on three-dimensional imaging assessment of alveolar bone. Methods: This study was included 11 men and 11 women (average age, 22.6 and 24.5 years, respectively) selected from among 127 patients. The horizontal widths of alveolar bone of maxilla and mandible were measured at the crestal, mid-root, and root apex level on MDCT (multi-detector computed tomography) images reconstructed by medical imaging software. In addition, tooth dimensions of the central incisors, canines, second premolars, and first molars of maxilla and mandible, including the horizontal width of the interdental alveolar bone crest, were also measured and statistically analyzed. Results: The horizontal alveolar bone width of the palatal side of maxilla showed a distinct increment from the alveolar bone crest to the apical region in both anterior and posterior areas. The average widths of the maxillary alveolar ridge were as follows: central incisor, 7.43 mm; canine, 8.91 mm; second premolar, 9.57 mm; and first molar, 12.38 mm. The average widths of the mandibular alveolar ridge were as follows: central incisor, 6.21 mm; canine, 8.55 mm; second premolar, 8.45 mm; and first molar, 10.02 mm. In the buccal side, the alveolar bone width was not increased from the crest to the apical region. The horizontal alveolar bone width of an apical and mandibular border region was thinner than at the mid-root level. Conclusions: The results of the preliminary study are useful as a clinical guideline when determining dental implant diameter and position. And also, these measurements can also be useful during the production of prefabricated membranes and customized alveolar bone scaffolds.
The purpose of this study was to estimate correlations of craniocervical posture and craniofacial morphology in Korean young adults. The sample consisted of 50 young adults (25 males and 25 females) who had good profile and Class I molar relationship. The analysis of craniocervical posture and craniofacial morphology was performed on lateral cephalograms taken in natural head position. The results were as follows, 1. The mean and the standard deviation of postural and morphologic variables were obtained. 2. Korean young adult had cervical lordosis of which degree between OPT and CVT shows $3.55{\pm}2.58^{\circ}$ 3. Craniocervical posture and each of vertical ratio, facial prognathism, mandibular rotation showed high correlation. 4. Correlation coefficients between postural variables and each of intermaxillary relation, anteroposterior ratio were low. 5. The head positioning error of natural head position was smaller than the inter-individual variability of postural variables.
The purpose of this study was to obtain the lingual morphology(angulation, inclination, horizontal and vertical contour) and lingual arch form of Korean adult with normal occlusion in order to provide the basic datas for lingual brackets and ideal lingual archwire. Dental models of thirty person with normal occlusion(Male : 16, Female :14) were selected for this study. Crown angulation, inclination. horizontal and vertical contour of lingual surfaces from Lt. 1st molar to Rt 1st molar of both upper and lower arch were measured. Lingual arcform was studied from copied papers of dental models attached Fujita lingual bracket. The results of this study were summarized as follows: 1. The average angulation and inclination of lingual surfaces of all tooth types for Korean adults with normal occlusion were obtained. 2. The average horizontal and vertical contour of lingual surfaces of all tooth types were obtained. 3. There were similar figures in horizontal and vertical contour of lingual surfaces between upper and lower molars, upper and lower premolars, upper and lower canines, upper central and lateral incisors and lower central and lateeral incisors respectively. It was possible that the use of those contour of bracket bases in common. 4. The average of lingual archform was provided, which was arch-shaped from canine to canine, linear along the premolars and molars with small offset bend between them, and where canines and premolars met, it was bent in a crank- shape. 3. There was no difference between lingual archform of male and that of female, although lingual archform of female was smaller than that of male in lower arch.
Even though there exist a lot of study about antibacterial effects and reactions of extracted materials from plant, few study exist about oral pathogenic bacteria. Therefore we tried to recognize about the suppression effect to the periodontal pathogenic bacteria and halitosis, when add some kinds of plant extracted materials, myrrh, rhatany, chamomolilla to saliva. We used Crude drug : Myrrh tincture (100mg/ml), Ratanhia tincture (100mg/ml), Chamomile tincture(100mg/ml). We inspected about the cariogenic bateriae, S. mutans GS5 and S. sobrinus 6715, periodontal pathogenic bacteria, P. gingivalis 2561, P. intermedia ATCC 25611, Candida albicans ATCC 18804, and E. feacalis ATCC 4083, then the result follow. The plant extracted material, myrrh, rhatany, chamomomilla, which have convergence effect, bacteriocidal effect and anti-inflammation effect, show an antibacterial effect and reaction to the oral pathogenic bacteria. And with treating rhatany that have the most strong antibacterial effect, through transmission electron microscopy we could see a severe morphologic change of bacteria. This means with the plant extracted material, we can suppress the oral harmful bacteria and prevent periodontal diseases, caries, halitosis and oral inflammations. And within the future studies for the improvement of oral hygiene, our result might be a clinical evidence.
