1.Motor Evoked Potential in Normal and Ischemic Stroke Patients.
Journal of the Korean Neurological Association 1989;7(2):266-275
Motor evoked potentials (MEP) were elicited with transcranial cortical stimulation using a magnetic coil in 33 normal subjects and 12 ischemic stroke patients with variable degree of motor weakness. Significant side effects or pain were not encountered. Normal thenar and tibialis anterior (TA) MEP latency measured 20.9+1.4msec and 29.3+1.9msec respectively. Thenar latency correlated with arm length more than height and TA latency correlated with height. The variability of MEP amplitude was great but thenar MEP amplitude exceeded 11% of the maximum thenar M wave. Thenar and TA MEP were evoked in all uninvolved site of ischemic stroke patients to contralateral cortical stimulation. No potentials were noted in involved site of 6 among 12 patients studied thenar MEP and 5 among 7 patients studied TA MEP and their motor powers were lower than those with elicited MEP. All involved site with motor power grade 2 or less in arm and grade 3 or less in leg elicited no potential. These findings suggest that the MEP is very sensitive to ischemic injury.

This study was undertaken to make current fetal growth curve throughout later part of pregnancy. 5,110 normal singleton deliveries at Il Shin Christian Hospital were included. The 10th, 25th, 50th, 75th, 90th percentiles of birth weight were calculated from 21 to 42 weeks' gestation and the 10th, 50th, 90th percentiles of birth weight compared by fetal sex, maternal parity and height were graphed to know the potency of factors. There was a linear growth pattern between 28 and 38 weeks' gestation. During last month of prgnancy, three factors have significant effect on median birth weight but no significant differences in 10th percentiles. Maternal height & parity significantly affeect on 90th percentiles. So, these factors must be considered when diagnosing large for date.

The hepatitis C vims(HCV) is now known to be the chief cause of transfusion-associated non-A, non-B hepatitis. The ultimate goal of blood donor screening for anti-HCV antibodies is the specific exclusion of vital carriers from the blood donor population. Recently, a third generation anti-HCV screening(Green Cross Center Innotest HCV 3.0 Genedia HCV 3.0 ) and immunoblot assay, Inno-Lia HCV Ab III (Innogenetics) using antigens derived from the core and different nonstructural regions(NS3, NS4 and Ns5) of the HCV viral genome were developed. To evaluate the usefulness of these assays, anti-HCV reaction patterns of the Inno-Lia HCV Ab III or presence of HCV-RNA detected by reverse transcriptase-polymerase chain reaction(RT-PCR) were examined samples in which were repeatedly positive or discrepant with Abbott EIA-2, Innotest HCV 3.0 Genedia HCV 3.0 The reaction intensity of Innotest HCV 3.0 Genedia HCV 3.0 was higher than that of Abbott EIA-2. The sensitivity and specificity of Innotest HCV 3.0 and Genedia HCV 3.0 were 92.9% and 86.8%, respectively, and the positive and negative predictive values were 72.2% and 97.1%. both. The sensitivity and specificity of Abbott EIA-2 were 100% and 78.9%, respectively, and the positive and negative predictive values were 63.6% and 100%, respectively. We concluded that the new third generation HCV EIA reagents can decrease a false positivity of second generation EIA reagents and correlate well with detection of HCV-RNA by RT-PCR.

Since the first description of the trisomy 9p in 1970, over one hundred cases have been described with the advanced chromosomal banding technique. Clinical findings include growth and mental retardation and facial dysmorphism. Crucial determinants of the classical features of this syndrome lie within the distal half of the chromosome 9 short arm. But this syndrome has not been reported in Korea, we are reporting a boy diagnosed by clinical features and chromosomal study that is trisomic for a partial short arm of a chromosome 9. A brief review of the literature is included.

OBJECTIVES: This study was for analyzing the research about international marriage immigrant women and a trial to find the right direction for future research. METHODS: Sixty articles published from June, 2004 to June, 2009 were reviewed and analyzed according to the general characteristics, major of author, and theme of health domains. RESULTS: Most of them were master's thesis(71.7%) and journals(21.7%) and doctoral dissertation(6.7%) have been published mostly after thesis. Among 83.3% for quantitative research, descriptive(33.3%) and descriptive correlation(41.7%) methods were the most used and there were some qualitative researches(16.7%). The most frequently used data gathering method was questionnaire(81.7%) and the next was interview(16.7%). The major rates of the author were 61.7% for social welfare and 2.1% for nursing. The investigated variables in social health domain were adaptation(28.3%), and communication(1.7%). In psychological health domain, marriage satisfaction(16.7%), life satisfaction(11.7%), and depression(10.0%) were most researched. Utilization of medical center(5.0%) and health promotion behavior(1.7%) were investigated in physical health domain. CONCLUSIONS: Above this, most articles were researched about the adaptation of international marriage immigrant women. But the life in foreign countries can cause physical and psychosocial unhealthy conditions, so many-sided health related researches are supposed to be conducted for adaptation and prevention health problems of international marriage immigrant women.

BACKGROUND: To determine the molecular structure of type II collagen-specific T-cell receptors associated with rheumatoid arthritis (RA). METHODS: We generated CII-specific T-cell lines of 8 RA patient s by prolonged in vitro culture with bovine CII (bCII) and the immunogenic peptide (256-270) of human CII. The proliferation response towards CII stimulation was measured from the uptake of 3 H-thymidine. Changes in the secretion of Th 1 and Th2 cytokines in the culture supernatent were measured by ELISA. The TCR clonotypes of these T-cells were examined by RT-PCR/ SSCP analyses of all 22 V beta chains. RESULTS: T-cells from patients' tissue exhibited strong proliferation index upon CII stimulation, which was maintained up to 6 months in the culture. The secretion of INF-gamma from these T-cells increased along with the duration of culture time, while the amount of IL-4 production did not show significant changes. The SSCP band patterns of patients' T-cells appear as discrete bands unlike the smeary streak produced from normal samples. Some SSCP bands, each representing selected expansion of a TCR containing certain subtype of V beta peptides, appeared to be identical in more than one patients. Among these, the expansion of SSCP band representing the V beta 14 CDR3 region persisted after switching the antigen to the immunogenic human peptide (256-270). CONCLUSION: CII-reactive T-cells expressing distinct CDR3 motifs are selectively expanded in the peripheral blood and synovial fluid of RA patients, and their persistent proliferation upon CII stimulation, as well as the production Th 1-type cytokines, may play pivotal roles in RA pathogenesis.

PURPOSE: This study was to investigate the effect of music therapy as intervention on peripheral neuropathic pain and anxiety of gynecologic cancer patients who were undergoing paclitaxel chemotherapy. METHODS: Hospitalized 62 patients were assigned to an experimental group (n=30) and a control group (n=33) in this quasi-experimental study. The experimental group participated in music therapy that includes listening, singing and song writing during 1 hour. The peripheral neuropathic pain, anxiety and depression were examined as pre-intervention evaluation by using pain scale, anxiety scale (20 questions) and depression scale (20 questions) in both groups. There were no further treatments for the control group while the experimental group involved in music therapy. The peripheral neuropathic pain and anxiety were evaluated in both groups as post-intervention evaluation. RESULTS: Outcomes were verified through hypothesis testing. The level of peripheral neuropathic pain and anxiety in the experimental group was decreased, compared to the control group. CONCLUSION: According to the study, music therapy is a beneficial intervention that reduces peripheral neuropathic pain and anxiety in gynecologic cancer patients. These findings are encouraging and suggest that music therapy can be applied as an effective intervention for minimizing chemotherapy related symptoms.

PURPOSE: The incidence of retinopathy of prematurity(ROP) which is one of the most common cause of childhood blindness has not decreased despite the restricted use of oxygen. There may be other factors responsible for ROP which could not be explained solely by improved survival of very low birth weight infants. We tried to clarify perinatal risk factors that are nrelated to the occurrence of ROP. METHODS: We enrolled 239 infants with gestational ages less than 33 wks or with birth weight less than 1,800 gm who had received ophthalrnologic examination between Jan. 1995 and Dec. 1997. The patients were categorized into two groups,' "No ROP" group as control(n=185) and ROP group as study population(n=54), and we compared the perinatal risk factors between the two. RESULTS: 54(22.6%) out of 239 infants were diagnosed as having ROP. The annual incidence of ROP decreased but the incidence of treated ROP increased. The incidence of ROP decreased with longer gestation and higher birth weight. Mean gestational age was 30.3 weeks in the study group vs 31.0 weeks in the control group, and mean birth weight was 1,390 gm and 1,586 gm, respectively. Significant factors contributing to increased incidence of ROP included: duration of oxygen therapy, ventilator therapy, total parenteral nutrition and hospitalization, frequency of hyperoxia, hypercarbia, and transfusion and respiratory distress syndrome, umbilical artery catheterization, intraventricular hemorrhage, sepsis, bronchopulmonary dysplasia, use of dexamethasone and aminophylline, pneumonia, air leak syndrome, and hyperglycemia. The incidence of ROP and treated ROP was not influenced by the mode of surfactant treatment(prophylactic vs rescue) in RDS patients and the mode of dexamethasone treatment(short vs long) in BPD patients. CONCLUSION: The risk factors for retinopathy of prematurity included gestational age, birth weight and duration of oxygen, as well as other aforementioned perinatal factors. The occurrence of ROP can be decreased by preventing preterm birth, minimizing the use of oxygen, and further morbidity can be prevented by performing proper ophthalmologic examination and doing an appropriate follow-up.

Invasive aspergillosis usually does not occur in immunocompetent patients. Recently, however, the incidence of invasive aspergillosis has been increasing in immunologically competent patients. It is difficult to diagnose neuroaspergillosis because of its varied radiological findings and clinical manifestations. We report a case of aspergillosis of the central nervous system, presenting as a mass-like lesion, in an immunocompetent patient. The patient was diagnosed after a surgical biopsy and treated with antifungal agents. The clinical outcome was good.
