Object：The purpose of this study was to investigate that infection with group $A[{\beta}]$ hemolytic streptococcus may associate the mechanisms that cause or exacerbate the tic symptoms in some cases of Tourette's disorder Method：Fourteen cases with abrupt worsening of tics participated in this study：10 males,4 females. The subjects were divided into two groups composing of the group with increasing level of ASO titer and the group with normal level of ASO titer. The subjects were administered Yale Global Tic Severity Scale(YGTSS). Result：The global severity scores and overall TS impairment rating scores of YGTSS in the group with increasing level of ASO titer were more higher than in the group with normal level of ASO titer Conclusion：These results suggest that increasing level of ASO titer, resulting from group $A[{\beta}]$ hemolytic streptococcal infection has affected worsening the tic symptoms in Touette's disorder.

The objectives of the present study were to provide comprehensive assessment of the impact of epilepsy on the psychological well-being of children with epilepsy and to identify the neurological factors associated with the psychopathology. The participant patients were recruited from the population of children and adolescent aged 7 to 16 attending the OPD of department of pediatric neurology in Seoul National University Hospital in Korea. We exclude mental retardation, pervasive developmental disorder and brain organic pathology. As control group, formal students were chosen and their sex, age, achievement, socioeconomic status were matched to patients. The first author interviewed the children and their family members and obtained the developmental history and family information. We used the following 10 scales for assessing psychological and behavioral problems in patients and their family member. The scales were standardized and their validity and reliability were confirmed before. Parent rating scales : Yale children's inventory, Disruptive behavior disorder scale, Parent's attitude to epilepsy questionnaire, Family environment scale, Symptom check-list-90 revision, Children behavior check-list. Children's self rating scales : Children's depression inventory, Spielberger's state-trait anxiety anxiety, Piers-Harris self-concept inventory and Self-administered Dependency questionnaire for Mother. The result showed the risk factors associated depression were early onset, complex partial seizure, lateralized temporal focal abnormality on EEG, Drug polypharmacy, high seizure frequency and sick factors associated anxiety were old age of patient, lateralized temporal focal abnormality EEG, Drug polypharmacy, high seizure frequency. Also the result of this present study indicated that risk factors associated oppositional defiant disorder, conduct disorder and attention deficit hyperactivity disorder were young age, male, early onset, lateral temporal EEG abnormality and high seizure frequency. According to these results, common risk factors associated psychological and behavioral problems were lateralized EEG temporal abnormality, high seizure frequency in neurological factors.

Objectives: An outbreak of dermatosis occurred at a city gas manufacturing factory in Pohang in Aug, 1998. The authors conducted a study to find the cause and prevent the dermatosis, Methods: We conducted a questionnaire survey of 73 workers in the factory twice, once or Aug. 14th and then Sept. 11th, 1998. Also, a dermatologist examined their skin lesions. We suspected ants as the cause, so we collected them for identification. Results: Twelve cases of dermatosis were identified with an attack rate of 16.4%. The attack rates were not different by age, educational level or tenures. The attack rates were 66.6% among production workers, 2.0% among clerical workers, 16.7% among tank trailer drivers and 0% among guards. The attack rate among production workers was significantly higher than that of the others (<0.01). There were no histories of the same dermatosis for the past one year. Histories of other skin diseases and allergies were very rare in both cases with skin diseases and control. Multiple, pruritic, rice-grained to bean sized erythemafous macules or papules with a central biting point could be found after initial severe itching occurred, Three cases showed signs of dermatosis with an allergic nature. The onset of dermatosis was between July 30 and Aug 12 and the durations varied from 5 days to over a month. The most frequent sites of stir lesions were the chest and abdomen (60.6%), and they were also observed on the neck (33.3%), arms (33.3%), shoulders (16.7%) and back (16.7%). Over 10 ants with their wings were collected in the work place and identified as Pachycondyla chinensis, subfamily Ponerinae. Conclusions : We thought that the outbreak of dermatosis was brought about by the ants flying into the work place through the open windows. Further studies on the factors contributing to the prosperity of the ants in this area are needed.

Objective : Accumulating evidence suggests a greater number of subcortical hyperintensities in the brain of patients with bipolar disorder. We studied the Clinical correlates of subcortical hyperintensities on magnetic resonance imaging in patients with Bipolar Disorder : Methods : Magnetic resonance images of the brain were obtained for 32 patients with bipolar disorder. The presence and location of hyperintensities were assessed. We compared clinical variables between patients with subcortical hyperintensities and patients without them. Results : Seven patients(21.8%) had subcortical hyperintensities, but among 8 patients who were 40 years or older, 5 patients(62%) had them. Age and age at onset of patients with subcortical hyperintensities were significantly older than patients without them. Psychotic symptoms were more frequent in patients with hyperintensities. Patients without hyperintensities had more familial loadings. Conclusion : Given the limitations of the study, our results should be seen as preliminary. This study, however, provides preliminary evidence supporting the notion that the onset, clinical feature and course of some bipolar disorders of late onset may be determined by underlying subcortical abnormalities, with such abnormalities being the consequence of factors related to aging or neurodegeneration(such as impaired cerebral circulation) rather than genetic factors which predispose to early-onset bipolar disorders.

This study was arranged to investigate effects of maternal nursing potential on immune metabolites in blood, body weight gain and occurrence of disease in Hanwoo calves. Forty experimental calves were used and allocated into two groups with different maternal nursing potential. Thus, high or low maternal nursing potential group had twenty calves, respectively. The concentrations of IGF-I, RBC, Ca and IP in blood were similar between two groups, except for RBC. RBC concentration in blood from high maternal nursing potential group was significantly higher compared with low maternal nursing potential group at 5 days after birth (p<0.05). The concentrations of IgG, albumin, total protein and GGT in blood were similar between two groups during the whole experimental period. The days from birth had no effects on the concentration of IgG, albumin and GGT in blood from two groups, except for total protein. Similarly, the maternal nursing potential had no direct effect on body weight of calves, but body weight in high maternal nursing potential group tended to be higher compared with low maternal nursing potential group at 6 months age. The occurrence of respiratory disease and diarrhea in high maternal nursing potential group was relatively lower compared with low maternal nursing potential group. Therefore, the present study indicating that maternal nursing potential had effect on growth, and immune system in relation to disease in calves.

We evaluated the possible clinical application of Non HDL-cholesterol and triglyceride to HDL-cholesterol ratio as a metabolic syndrome predictor for the elderly in Korea. 1,543 elderly persons aged 65 years or older who visited the health examination center of Gyeonggi Regional General Hospital from January 2015 to December 2017 and had a health checkup were enrolled in this study. Metabolic syndrome was diagnosed based on the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) standards. Abdominal obesity was assessed by the Asia-Pacific standards presented at the World Health Organization (WHO) West Pacific Region. Non-HDL-cholesterol was calculated as the difference between total cholesterol and HDL-cholesterol. The metabolic syndrome predictive power was higher for triglyceride to HDL-cholesterol ratio than for Non HDL-cholesterol. After correcting for related factors, triglyceride to HDL-cholesterol ratio was higher in the $4^{th}$ quartile, which had a higher risk of developing metabolic syndrome, than in the $1^{st}$ quartile. The optimal cutoff value for the triglyceride to HDL-cholesterol ratio that predicts the onset of metabolic syndrome was 2.8. triglyceride to HDL-cholesterol ratio can be a simple and practical indicator of the risk of metabolic syndrome.

This study aims to provide important data for community-centered rehabilitation by examining factors influencing community participation after the onset of stroke. The study subjects were 100 patients with a stroke for more than six months. Korean Craig Handicap Assessment and Reporting Technique (K-CHART) was conducted to determine the level of participation of subjects, and Korean-Modified Barthel Index (K-MBI) was conducted to examine the factors influencing the community participation of the subjects to determine the level of independence of activities of daily living. As a result, the relevant factors of community participation in stroke patients were as follows. Physical independence, cognitive independence, mobility, work, and social integration of stroke patients showed higher explanatory power than engagement in activities of daily living, age, and employment. Also, physical independence, cognitive independence, mobility, work, and social integration were factors that affected participation. All items were statistically significant (p <.01). It is considered that this study will contribute to providing information for focusing on occupational therapy for increasing the social participation of stroke patients, and proper evaluation and intervention will work as essential rehabilitation factors for improving participation with respect to the influential factors of participation.

For the development of a multifunctional biocontrol agent, the siderophore-producing strain GL7 was isolated from a rhizosphere on chrome azurol S agar. The GL7 was identified as a strain of Pseudomonas fluorescents on the basis of their reactions to standard physicochemcial tests from Bergey's manual, API diagnostic test, and fatty acid analysis. P. fluorescents GL7 considerably inhibited spore germination and hyphal growth of phytopathogenic fungus Funsarium solani in a dual culture. In pot trials of bean with P. fluorescens GL7, the disease incidence was significantly reduced down to 5% from 70% of incidence in the untreated control. P. fluorescens GL7 also enhanced plant growth to nearly 1.5 times than that of the untreated control, promoting elongation and development of the roots. These results suggest that the plant growth-promoting P. fluorescens GL7 can play an important role in the biological control of soil-borne plant disease in a rhizosphere.

A clinical analysis was done on 134 cases with bronchial asthma who were admitted to the Department of Pediatrics Yeungnam University from May 1987 to October 1991. The results were as followings; 1) The peak age of bronchial asthma was under 2 years. The sex ratio of male to female was 2.9 : 1. 2) The out-break of bronchial asthma was most common in fall, especially in September. 3) The past history of other allergic diseases were present in 22.4% of patients(30/134 cases), and the previous bronchiolitis in infancy were experienced in 12.7% of patients(17/134 cases). 4) According to the skin test for allergens done by RAST, the most common allergens were Mites and House dust. 5) Eosinophilia(T.E.C>250/min) was found in 29.1% of patients, and elevated IgE level(>200 $IU/m{\ell}$) was found in 63.2% of patients. 6) No significant differences in the serum IgE level were found between male and female patients. No significant differences in the serum IgE level were found between asthma patients with and without other allergic diseases. 7) The serum IgE level of school aged patients was significant higher than that of preschool aged(p<0.01).

Purpose : The prevalence of Reye syndrome has decreased since late 1980's. But we report that recently there were concentrative attacks of Reye syndrome after acute enteritis during the neonatal period. Methods : Clinical symptoms and laboratory results(quantitative organic acid analysis, routine chemistry, arterial blood gas analysis, serum ammonia) of seven patients admitted at the Samsung Medical Center, Sanggye Paik Hospital, Wonju Christian Hospital and Chuncheon Sacred Heart Hospital, referred from Jan. 2005 to Apr. 2005, were analysed retrospectively. The major clinical symptoms were derived from the patients' clinical records sended with urine samples and quantification of organic acids were done with gas chromatography and mass spectrometry. Results : The mean age of seven cases is 18 days and the major preceding symptoms were gastrointestinal symptoms(vomiting, diarrhea, refusal to feeding). The major clinical symptoms were clouded conciousness, repiratory difficulty, vomiting, seizures, and diarrhea. One patient died; that patient's serum ammonia was twenty times higher than normal. Conclusion : The seven patients were neonates. Reye syndrome has been known to be closely related with upper respiratory infections as a preceding disease and to internal use of aspirin, but in our study, the major preceding disease of the seven cases was gastrointestinal infection and none of these used aspirin.
