BACKGROUND: Korea is, known to be an endemic area of viral hepatitis B, and 5-6% of population are carriers. Immunization can reduce the spread of hepatitis B infection. Hower, not all people respond to hepatitis B immunsation. 5-15% of primary vaccinees fail to be immunized. After revaccination, only 37.5 44% of the primary failures elicit antibody response. Recent studies have reported that it is effective to inject a double dose vaccination in immunocompromsed patients. In some country, they recommend that neonate whode mother is HBV carrier shoud receive double dose vaccination. This study documented the results of double dose vaccintion only once to nonrsponders toward the HBV immunzation. METHODS: Healthy nonresponders to Hepatitis B immunization were recuited from Sep. 1995 to Aug. 1996. Subjects with their AST/ALT level over 40, or over 65 years old were excluded. They were received 2ml of plasma-derived vaccine(Hepavax-B) intramuscularly in the deltoid muscle. Anti-HBs antibody testing were performed at 1 to 3 months after vaccintion. RESULTS: 17 healthy nanreponders to Hepatitis B immunization(male 10, female 7) were included. Their mean ages were 47(32 to64), AST/ALT level 20/19(16 to 28/11 to 35), smoking 4.3pys(1 to 7). Seroconversion occured in 13 of them(76.5%). CONCLUSIONS: Nonresponders to Hepatitis B vaccintion respond well to double dose vaccination once.

PURPOSE: Actinomycosis is still a relatively rare infection, characterized by multiple abscesses, draining sinuses and the appearance of sulfur granules, which are valuable in aiding the diagnosing the discharge of involved tissues. In most instances, the onset of an abdominal disease is preceded by inflammatory or a traumatic incident resulting in the perforation of the mucosa of the gastrointestinal tract. Intensive and prolonged antimicrobial therapy, and wide surgical excision of involved tissues are the two general principles of therapy. METHODS: We experienced 8 cases of abdominal actinomycosis after a laparotomy between March 1997 and February 2002. RESULTS: The results were as follows: 1) There was a 1: 1 male to female ratio of abdominal actinomycosis, and a mean age of 47 years. 2) The clinical features were different for each involved organ, -but, most of the clinical symptoms were nonspecific to suspect actinomycosis. 3) The frequently involved organs were mainly located lower abdomen, such as the appendix and cecum, sigmoid colon and small bowel. 4) In 60% of the patients, the predisposing factors were identifiable, these being: a previous abdominal operation, IUD and abdominal injury. 5) The preoperative diagnoses included: acute appendicitis, and periappendiceal and intra-abdominal abscesses. The pre-exploratory diagnoses were made by ultrasound and abdominal CT. 6) Explorations were performed in all patients, depending on their diagnosis, to afford the proper surgical treatment and correct diagnosis. After the operation, all the patients were treated with oral antibiotics for long period. CONCLUSION: The authors conclude that pre-exploratory cytological or culture studies, with careful history taking, for low abdominal tumors or abscesses may increase the rate of correct diagnosis, as could proper explorations.

The Psychopathology of schizophrenia is composed of many heterogeneous symptom complex, and multifaceted approaches have been done on this subject. It is so simplified a method that the complex symptoms of schizophrenia are classified into only positive and negative symptoms. Preceded studies of other researchers said cognitive deficit of the schizophrenics played important roles in the symptom formation. The purpose of this study is the evaluation of the relationship between the symptoms of schizophrenia and the memory function and low level of cognitive function. In this study, 30 subacute and chronic schizophrenic patients were included. PANSS(Positive and Negative Symptom Scale) was applied to evaluate the clinical symptoms in each subject. The memory function and low level cognitive function were evaluated using WMS-R(Wechsler Memory Scale-revised version) and Decision-reaction timer. The results showed negative correlations between cognitive factor of PANSS(5 factor model) and delayed recall of WMS-R. These results suggest the possibility that symptom evaluation using PANSS can be a preliminary estimation of cognitive function in schizophrenia.

OBJECTIVES: On the basis of the relationship between positron emission tomography and symptom profiles in schizophrenia by Liddle et al, the authors attempted to investigate the related brain regions associated with clinical symptoms by studying the correlations between the performance of neuro-psychological tests likely to reflect functioning of dorsolateral preftontal, orbitofiontal or cingulate, parietal, and temporal cortices and 3 dimensions (psychotic or reality distortion, negative, and disorganization) of symptoms. METHODS: 41 subjects with a confirmed diagnosis of schizophrenia were scored for each of the three dimensions by Positive and Negative Syndrome Scale. Subjects performed 12 neuropsychological tests designed to measure impairment in specific areas of the brain. RESULTS: According to partial co-rrelations to remove possible confounding variables, the neuropsychological correlates of psychotic(reality distortion) and disorganization dimensions were some tests considered to be related to dorsolateral prefrontal and parietal lobes, and cingulate and dorsolateral preliontal cortices, respectively. CONCLUSION: The results support a part of hypotheses, a specific relation between disorganization and cingulate cortex. In addition our results suggest the possibile relations between a psychotic dimension and functions of dorsolateral prefrontal and parietal lobes, and between a disorganization one and functions of cingulate and dorsolateral prefrontal cortices. The authors believe that our study supports different neural circuits associated with each of dimensions of symptoms, particularly psychotic and disorganization, in schizophrenia.

To investigate the mechanism of monocrotaline-induced pulmonary arterial hypertension, authors performed immunohistochemical study using antibody to von Willebrand factor(vWF), cell kinetic study using 5-bromodeoxyuridine and ultrastructural study after single subcutaneous injection of monocrotaline(MCT) to Wistar rats. The results of this study demonstrated that the expression of vWF by pulmonary endothelial cells was markedly increased from day 3 until 2 months after MCT injection. The labeling index of pulmonary microvessel endothelium began to increase after six days and was maximal on the third weeks, and thereafter it remained slightly increased above basal level. Electron microscopic study revealed attachment of inflammatory cells an platelets to endothelium from 6 hours and degranulation of attached platelets 24 hours after MCT injection. Evidences of endothelial injury began to appear from 12 hours after MCT injection. Evidences of endothelial injury began to appear from 12 hours and was maximal after 48 hours. From the third day, ultrastructural change of cell regeneration and hypertrophy began to appear and was continuosly observed until 2 months. In addition, we evaluated the changes in the number of pulmonary neuroendocrine cells using antibody to gastrin releasing peptide but it demonstrated no change until 2 months suggesting no role of neuroendocrine cells in the development of pulmonary hypertension of Wistar rats at early stage. In conclusion, the results indicate that pulmonary hypertension by MCT injection is due to increased vascular resistance caused by vasoconstriction and hyperplasia of endothelium with musculariz ation of the pulmonary arterioles induced by endothelial dysfunction and some biologic substances released form endothelium and platelets.

BACKGROUND AND OBJECTIVE: The outcome of asthma treatment has traditionally been assessed by measuring the conventional clinical parameters such as symptoms, expiratory flow rates and needs for medications. But none of them tells us whether the patients are actually able to function properly in their lives. Only assessment of the quality of life (QOL) can reflect the parts of patients lives affected by the disease. However, there is no measure to assess the quality of life of patients with any chronic diseases in Korea yet. We developed the QOL Questionnaire for Korean Asthmatics and evaluated its measurement properties. METHOD: The questionnaire was composed of 18 items in four domains : i.e. activity limitation (6 items), symptoms (5 items), emotional function (3 items) and environmental stimuli (4 items). At our out-patient clinic, 32 adults with moderate to severe persistent bronchial asthma were enrolled. The study design consisted of 4 week unblinded single cohort with visits at 0 and 4 weeks, and the patients were asked to answer the questionnaire by self administration method at the two separate visits. Forced expiratory volume for 1 second (FEV1) and peak expiratory flow rate (PEFR) were recorded at each visit. According to the patients and physicians global assessment, the patients were divided into two groups, i.e. stable and changed (improved). The responsiveness, reproducibility and validity of the questionnaire were evaluated. RESULTS: The total QOL scores at the second visit in the changed group were significantly higher than those at the first visit. The score differences between the two visits in the changed group were higher than in the stable group. In the stable group, the responses to the questionnaire were reproducible. The QOL scores showed good longitudinal correlation with the expiratory flow rates, whereas FEV1 did not correlate with the QOL in cross-sectional analysis. CONCLUSION: The questionnaire proved to be reproducible, responsive and valid in the subjects. It could be recommended for the outcome evaluation of Korean asthmatics.
