We experienced three young patients with diffuse lymphoid hyperplasia of the gastric antrum. The peculiar nodularity of the stomach in tliese patients is another cause of etat mammelanne in addition to hypertrophic gastritis and prominence of the areae gastricae. The etiology of the diffuse lymphoid hyperplasia of the gastric antrum is not known. The symptqm is not specific and not related to hitologic and gastroscopic finding but rather to psychological disturbance. We propose longstanding observation for the change of the nodularity.

In order to investigate the level of lead exposure of workers in litharge making industry and to evaluate how lead exposure, personal habit such as smoking and drinking affect the prevalence of lead related symptoms and other study variables, we investigate 114 workers(24 office workers and 90 lead exposed workers) in a litharge making industry. Study variables chosen were blood lead(PbB), zinc protoporphyrin in whole blood(ZPP), Hemoglobin(Hb), hematocrit (Hct), SGOT and SGPT. symptom questionnaires which had 15 lead exposure related symptoms were provided to all workers and filled up by themselves and reconfirmed by physician. The results obtained were as follows; 1. The mean value of PbB, ZPP and SGOT in lead exposed group were higher than those of non-exposed group, and there were no differences of means in other study variables. 2. The smoking and drinking rate of study subjects were 65.8% and 71.0% as a whole. Smoking rates were lower in non-exposed group than exposed group, but drinking rate were not. 3. There were no differences of mean values of study variables between smoker and non-smoker in non-exposed and exposed group, but there was a difference of mean value of SGOT between drinker and non-drinker in lead exposed group. 4. while the symptom prevalence of lead exposed group were higher in neuromuscular category than non-exposed group, those of non-exposed group were higher or same with exposed group in gastrointestinal and general symptom category. 5. The symptom prevalence of smoker were higher than non-smoker regardless of exposure. 6. The symptom prevalence of drinker were only higher in gastrointestinal symptom category than non-drinker. 7. In multiple stepwise regression analysis of lead related symptoms as dependent variable and blood lead, smoking habit, drinking habit and work duration as independent variables, drinking habit contributed to the gastrointestinal symptom category, whereas blood lead and smoking contributed to the neuromuscular symptom category. For the total symptoms work duration and smoking habit contributed significantly.

Antifungal bacteria for biological control of plant diseases or production of novel antibiotics to plant pathogens were isolated in 1997 from various soils of Ansung, Chunan, Koyang, and Paju in Korea. Sixty-four bacterial strains pre-screened from approximately 1,400 strains were tested on V-8 juice agar against eight plant pathogenic fungi using in vitro bioassay technique for inhibition of mycelial growth. Test pathogens were Alternaria mali, Colletotrichum gloeosporioides, C. orbiculare, Fusarium oxysporum f. sp. cucumerinum, F. oxysporum f. sp. lycopersici, Magnaporthe grisea, Phytophthora capsici, and Rhizoctonia solani. A wide range of antifungal activity of bacterial strains was found against the pathogenic fungi, and strain RC-B77 showed the best antifungal activity. Correlation analysis between inhibition of each fungus and mean inhibition of all eight fungi by 64 bacterial strains revealed that C. gloeosporioides would be best appropriate for detecting bacterial strains producing antibiotics with potential as biocontrol agents for plant pathogens.

Objectives:
To compare the white matter microstructure alterations in schizophrenia with auditory verbal hallucinations (AVHs) with normal persons using diffusion tensor imaging.
Methods:
Thirty-five schizophrenia patients with AVHs and 33 normal control persons were recruited from the National Forensic Hospital in Korea. The fractional anisotropy (FA) values of arcuate fasciculus (AF), Broca’s area, and Wernicke’s area were estimated from the diffusion tensor imaging data of each subject using the Johns Hopkins University-white matter tractography atlas to determine the difference in white matter integrity between schizophrenia patients with AVH and normal persons.
Results:
Compared to the normal control group, the FA values of AF (t=4.349, p<0.001) were higher in the normal control group. On the other hand, there were no significant differences in Broca’s area and Wernicke’s area.
Conclusion
Microstructural changes of AF are certainly involved in schizophrenia patients with AVHs.

BACKGROUND: Guillain-Barre syndrome is defined as a recognizable clinical entity that is characterized by rapidly evolving symmetric limb weakness, the loss of tendon reflexes, absent or mild sensory signs, and variable autonomic dysfunctions. This study evaluated the clinical and electrophysiological findings retrospectively. MATERIALS AND METHODS: Forty-five patients with Guillain-Barre syndrome, who were admitted to the Yeungnam University Hospital for six years from Jan. 1994 to Dec. 1999 were investigated. The correlation between the clinical manifestation and the electrophysiological study was evaluated. RESULTS: The male to female ratio was 1.8: 1 and there was a peak seasonal incidence in the winter. A preceding illness was noted in 66.7% of cases, and an upper respiratory tract infection was the most common one. The most common clinical manifestations were a loss of tendon reflex and ascending muscle weakness and paralysis. The cerebrospinal fluid examinations revealed, albuminocytologic dissociation in 33 cases (73.3%). Intravenous immunoglobulin therapy was performed in 29 cases (64.4%). The sequential electrophysiological abnormalities were most marked at 2 to 4 weeks after onset. At that time the most significant change was a decrease in the compound muscle action potential amplitude. These 45 patients with Guillain-Barre syndrome were subclassified using the clinical and electrophysiological data. CONCLUSION: The result in this study, concured with other research on the clinical and electrophysiological data of Guillain-Barre syndrome. However, an extensive and dynamic investigation is necessary to determine the reason for the peak seasonal incidence in winter.

To evaluate the follow-up management state and related factor of lead battery workers in periodic health examination as part of program of group occupational health service, author studied 293 workers with questionnaire on knowledge of results and follow-up management state and related factors, and compared the responses to their periodic health examination result charts. The results were as follows: 1. 252(86%) workers responsed that they had received the health examination result chart, but only 116(39.6%) workers responsed that they had been educated or explained about the result of health examination, and 11(57.9%) workers among 19 workers with non-occupational disease D, 101(44.3%) workers among 228 workers with non-occupational disease C, and 19(28.4%) workers among 67 workers with occupational disease C knew accurately their health examination results. 2. 78(24.8%) of the workers responsed that they had follow-up management, and contents of follow-up management were follow-up(36.6%), out-patient treatment(31%), change worksite(8.5%), temporary retirement(7.0%) and others(16.9%). 3. Most of the workers responsed that the health examination were necessary, but three-fourths of the workers responsed that the health examination had been superficial or that they didn't know. 4. In this study, follow-up management show significant association with only explanation or education about health examination result chart.

Three dimensional analysis of malocclusion and craniofacial deformation is essential for the successful orthodontic treatment. But the orthodontists are not familiar with diagnosis and treatment plane based on lateral cephalometric analysis. Since orthodontists do not posses a sufficient knowledge in standard value of posteroanterior cephalometric anaysis and of clinical importance for transverse jaw growth. In this study male(n=130) and female(n=171) aged from 6 to 16 and diagnosed as Class I malocclusion were selected to analysis width of cranium, maxilla and mandible on the posteroanterior cephalogram. The changes as a function of chronologic age and cervical vertebrae maturity index(CVMI) were examined. The proper regression model was selected by sex with polynominal regression models and method of variable selection. Mean of each measurements and 70% confidence interval of individual measurement according to age was assesed and a graphs were made. Results are as follows : 1. All the measurements for the width are gradually incresed as increase in chronologic age and CVMI. From the total amount of change between age 6 and 16, there is a tendency that mandibular width is broader than maxillary width and the width of male is broader than female. 2. There is no statistically significant sexual difference in Mx-Mn difference, Mx-Mn width differential, Mx/Mn ratio according to age and CVMI. 3. Mean of each measurement and 70% confidence interval of individual measurement according to age and sex were assessed and graphs were made for maxillary width, mandibular width, Mx-Mn difference, Mx/Mn ratio. 4. The width of maxilla and mandible in Korean children are broader than Western children during growth period.

Parricide, the crime of murdering a parent, accounts for about 5% of all homicides. Filicide is the crime of murdering one's own child. This study aimed to review demographic features and criminal characteristics of individuals who committed parricide and filicide in Republic of Korea (ROK). This study is based on data from the Korea Police Crime Analysis System, from 2006~2013. We assessed the diverse characteristics of both victims and perpetrators. Over the selected period, 381 parents were killed by their children and 230 children were killed by parents in the ROK. Parricides caused by schizophrenic murders accounted for 39.6% of all cases. Moreover, approximately 44.4% of the perpetrators attempted suicide following the maternal filicide. In our findings, psychiatric illness was a very important predictor in parricide, and these further suggest that young mothers with severe mental illness require careful monitoring by mental health support service.

9.Effect of Home-visit Nutrition Education for the Elderly with High Fasting Blood Glucose Levels.
Korean Journal of Community Nutrition 2006;11(3):346-360
This study was conducted to evaluate the effects of home-visiting nutrition education for the elderly with high fasting glucose level in an urban community. The study subjects were 40 elderly people, whose information on general characteristics, anthropometric measurement, biochemical indices, nutrition knowledge, nutrition attitude, dietary habit, food intake and nutrient intake were obtained at baseline. The education group received 6 weekly visits of home-visiting nutrition education from 15 March to 25 April 2004. In the baseline-survey, the education group and non-education group showed no differences in their general characteristics, health-related characteristics, anthropometric measurements, biochemical indices, nutrition knowledge, nutrition attitudes, dietary habits, and food and nutrient intake levels. The difference of mean change of nutrition knowledge, nutrition attitude and dietary habit after home-visiting nutrition education had been studied. The nutrition knowledge score increased by 1.4 in the education group; however, those in the non-education group which increased by 0.4, thus, the differences of mean change were statistically significant (p<0.05). The nutrition attitude score increased by 1.2 in the education group; however, those in the non-education group decreased by 0.4, thus, the differences of mean change were statistically significant (p<0.01). The dietary habit score increased by 1.7 in the education group; however, those in the non-education group decreased by 2.8, thus, the differences of mean change were statistically significant (p<0.01). The difference of mean change of anthropometric indices and biochemical indices in education group and the non-education group was not significant. Looking over the zcereals and their products, vegetables, seaweeds, meats and their products, and fish than the non-education group. The MAR increased by 0.06 in the education group; however, that in the non-education group increased by 0.01, thus, the differences of mean change were statistically significant (p<0.05). The differences of mean change of fasting blood glucose and biochemical indices after home-visiting nutrition education were studied. Fasting blood glucose decreased by 7.6 mg/dL in the education group; however, in the non-education group which increased by 0.4 mg/dL, the difference of mean change was not significant (p=0.051). The above findings suggest that home visiting nutrition education increases the nutrition knowledge and nutrition attitude, as well as, it is effective to change dietary habits. If the education period is extended, not fasting blood glucose improvement was insignificant, but fasting blood glucose improvement ability could be found by changing dietary habits.

The Korean Journal of Thoracic and Cardiovascular Surgery 1999;32(8):702-708
BACKGROUND: Surgical closure of the PDA in premature infants with complications or contraindications to indomethacin use, or recurrence of symptomatic PDA is a safe and effective procedure with low operative risk and minimal complications. MATERIAL AND METHOD: From April 1996 to August 1998, 11 premature infants with body weight under 1.5 kg at operation underwent operation for a symptomatic PDA (male:5, female: 6). Associated dise ases were congenital heart disease(7), hyaline membrane disease(6), intraventricular hemor rhage(4), pneumonia(4), pneumothorax(3), hyperbilirubinemia(2), necrotizing enterocolitis(2), renal failure(1), epilepsy(1), and hydrocephalus(1). Surgical techniques are hemoclipping(8) and ligation(3). The size of PDA was 3~6 mm (5.0+/-1.2). RESULT: Systolic and diastolic blood pressure rised and heart rates decreased after PDA closure. ABGA improved postoperatively. There were no surgical complications. Six infants with improved ABGA data were weaned from mechanical ventilatory support. The follow-up durations after discharge were 3 month to 12 month. Five deaths were not related to operation. The causes of death were hyaline membrane disease(2), bronchopulmonary dysplasia with pneumonia(1), sepsis(1), and con gestive heart failure with respiratory distress syndrome(1). CONCLUSION: Early operative closure is the treatment of choice in most premature infants with a hemodynamically significant shunt(PDA), recurrence of symptomatic PDA, complications of Indomethacin, or contraindi cations to Indomethacin.
