PURPOSE: Activated charcoal (AC) has been widely used as a universal antidote. Currently, emergency medical centers in Korea cannot administer AC due to discontinuation of the supply of commercial ready-mixed AC suspension. This study was conducted to investigate the proportion of emergency medical centers that administer AC to poisoning patients and provide basic information for emergency physicians and toxicologists. METHODS: A prospective telephone survey of all of the included emergency medical institutions was conducted. The type of emergency medical institution, average annual number of patients admitted to the emergency department, annual average number of patients who were poisoned and whether the hospital currently utilizes gastric lavage and administration of AC were determined. RESULTS: AC was administered to poisoning patients in 40% of regional emergency medical centers, 59.3% of local emergency medical centers, and 45.9% of local emergency medical rooms. Overall, 37% of total emergency medical institutions did not administer AC due to discontinuation of the commercial ready-mixed AC suspension. Additionally, 77% of emergency physicians in institutions without AC knew AC is necessary for poisoning patients. The rate of vomiting experienced by the medical staff according to types of charcoal showed that the average rate of vomiting was 33% for commercial ready-mixed activated charcoal suspension and 51% for self-prepared charcoal powder (p=0.02). CONCLUSION: AC should be secured promptly in emergency medical institutions. Before the supply of commercial ready-mixed AC suspension becomes again it is essential to develop a standardized regimen for self-preparation of charcoal powder and to educate emergency physicians and toxicologists to its use.

OBJECTIVES: This study was performed to study the way of thinking and satisfaction level of North Korean defectors in South Korea on various topics and their relationship with each other. METHODS: Direct interview was performed for 553 North Korean defectors in South Korea. 44 items of life satisfaction were rated. Satisfaction level was rated on a 5 point scale (1-unsatisfactory and 5-fully satisfied). Factor analysis and correlation of the factors were performed. RESULTS: The average level of satisfaction was 3.39. Relatively high satisfaction items were adjustment of their children, family life, and residence area. But relatively low satisfaction items were psychological and mental area, leisure, and income. In governmental support systems, medical support was the most satisfactorily rated item, but financial support for settlement and support for employment or job training were the most dissatisfied. In the factor analysis, 44 items of satisfaction were grouped into 13 factors. The correlation of these factors showed that general satisfaction is significantly correlated with satisfaction with housing, economic status, governmental support and lower degree of confusion on the sense of value. Confusion on the sense of value was high when defectors do not have close friends, have difficulties in understanding South Korean people, and are not satisfied with their economic status. Religion did not have significant correlation with the their sense of value. And self and social consciousness of the defectors were strongly correlated with the their employment status. CONCLUSION: This result showed that the satisfaction of North Korean defectors is correlated not only with material aspects, but also psychological and mental aspects. The results of study should be considered in helping defector to adjust to living in South Korea.

Environmental studies regarding Paragonimiasis have been done in Sulak-Myun, Kapyung-Goon (I district) and Yongmoon-Myun, Yangpyung-Goon (II district), both of which are considered "active" endemic areas, and in Byukje-Myun, Koyang-Goon (III district) an "arrested" area. 1. Paragonimiasis is still active in the Uhmos River, Sulak-Myun, Kapyung-Goon, where 49% of crayfish contained Paragonimus metacecaria. Snails which are the first intermediate host of Paragonimus westermani were moderately present. In the Oonke River, Yongmoon-Myun, Yangpyung-Goon, crayfish which are the second intermediate host of Paragonimus westermani, were found in every area of the river, but snails were not found in any area of either branch of the river. They were caught in areas which are located below the junction. In the Daeja river, Bykje-Myun, Koyang-Goon, crayfish were found only in the upper stream of the river and snails were not caught in any area of the river. 2. The results described above are attributed to the fact that snails, which have minimal mobility and vitality, were complete1y obliterated by the long, unprecedented drought in 1965. In contrust, crayfish with great mobility and vitality survived. Thus without the snail, the life cycle of Paragonimus western1ani become incomplete, and the clinical disease disappeared. 3. Rainfall is very important in maintaining water flow in the river, a necessary factor for the life cycle of Paragonimus westermani. Therefore we have charted tile amount of rainfall in the Seoul and Choonchun areas in 1965, compared with the average of the past 30 years, in order to ascertain the degree of drought which influnced the Paragonimus westermani hosts and cohabitants. 4. Geographic conditions which are also very important in maintaining water flow in small rivers was investigated. The conclusion was drawn, that a long river has an advantage over a short during drought; a tortuous river provides a better opportunity for miracidia of Paragonimus westermani eggs to migrate to snails, and for Pargonimus cercaria to invade crayfish than a straight rapidly flowing river. 5. We must conclude that man may ingest Paragonimus metacercaria by drinking water from shallow wells and streams in areas endemic to paragonimiasis, when we note that one crayfish of four caught in shallow wells in Kapyung-Goon contained many Paragonimus metacercaria. 6. Other factors are the increase in traffic due to the expanding population in Korean farm areas, and the increase in the use of farm chemicals, which seep into the rivers and reduce the number of snails, crayfish and crabs available as potential hosts. 7. In recent years, the wild fauna in the mountains, one of the important terminal hosts of Paragonimus westermani, have been markedly reduced in number. This may have contributed to decreasing paragonimiasis as directly infective to man. 8. Health education on paragonimiasis, informing the people of the dangers of eating raw or inadequately cooked crayfish and crabs, or those soaked less than 10 days in soysauce, and drinking the water from shallow wells and streams, is demonstrated to have decreased the incidence of this disease. 9. Because of the preceding facts, paragonimiasis in Kyunggi-Prvince is being decreased.

A 46-year-old man presented with a six-month history of recurrent episodes of abnormal behaviors characterized by agitation, anxiety, aggression, impulsion, and depression. They were not accompanied by obvious convulsions. Brain MRI demonstrated cerebromalacia from previous traumatic brain injury in both frontal and left anterior temporal lobe. Interictal EEG showed a focal seizure disorder arising from both temporal areas. Following antiepileptic medication, the abnormal behaviors disappeared. These results suggest that non-convulsive status epilepticus or a cluster of seizures could account for prolonged behavioral disturbances.

PURPOSE: alpha-Galactosylceramide (alpha-GalCer)-stimulated human Valpha24 natural killer T (NKT) cells exert antitumor activity against some leukemia in a CD1d dependent and TCR-mediated manner, but could not kill CD1d-negative neuroblastoma (NB) cells. There are few reports about the direct antitumor effect of highly secreted cytokines by these cells on activation. In this study, using a cell-free supernatant (SPN) collected from plate bound hCD1d/alphaGalCer tetramers-stimulated NKT cells, we examined whether they could be helpful in the immunotherapeutic treatment of NB. METHODS: Cells were cultured in IMDM. The cytokines produced by NKT cells were measured with Cytometric Bead Array (CBA) analysis. Cell viability was evaluated by calcein-AM fluorescence with digital image microscopy scanning (DIMSCAN). The percentage of specific apoptosis was calculated by flow cytometric detection of apoptosis using annexin V and 7-AAD. RESULTS: The activated NKT cells secreted high levels of IL-2, INF-gamma, TNF-alpha. The SPN was significantly cytotoxic against four out of eight tested NB cell lines, through mainly apoptosis as evidenced by annexin-V staining and inhibition with the pretreatment of pancaspase blocker. This apoptosis was significantly inhibited when anti-TNF-alpha and anti-IFN-gamma neutralizing mAbs were used separately and it was completely abolished when the two mAbs were combined. CONCLUSION: IFN-gamma and TNF-alpha produced by NKT cells could exert synergistically direct anti-tumor activity through apoptosis on some NB cell lines.

High mobility group-1 (HMGB-1) enhances the DNA interactions and possesses a transcriptional activation potential for several families of sequence-specific transcriptional activators. In order to examine the effect of HMGB-1 on the cell cycle progression in MCF-7 cells, the HMGB-1 expression vector was transfected into synchronized MCF-7 cells, and the effect of HMGB-1 overexpression on the cell cycle was examined. The HMGB-1 protein level in the transfected cells increased 4.87-fold compared to the non-transfected cells. There were few changes in the cell cycle phase distribution after HMGB-1 overexpression in the MCF-7 cells. Following the estrogen treatment, the cell cycle progressed in both the HMGB-1 overexpressed MCF-7 and the mock-treated cells. However, a larger proportion of HMGB-1 overexpressing MCF-7 cells progressed to the either S or G2 phase than the mock-treated cells. The mRNA levels of the cell cycle regulators changed after being treated with estrogen in both the HMGB-1 overexpressing MCF-7 and the mock-treated cells, but the changes in the expression level of the cell cycle regulator genes were more prominent in the HMGB-1 overexpressing MCF-7 cells than in the mock-treated cells. In conclusion, HMGB-1 overexpression itself does not alter the MCF-7 cell cycle progression, but the addition of estrogen to the HMGB-1 overexpressing MCF-7 cells appears to accelerate the cell cycle progression.

PURPOSE: The purpose of this animal and clinical study was to compare intra-arterial(IA) scintigraphy withangiography in the localization of gastrointestinal (GI) bleeding. MATERIALS AND METHODS: After sedation withintramuscularly administered ketamine, lower GI bleeding was induced in ten rabbits. Using inguinal cut-down, anarterial femoral 3F catheter was placed in the proximal mesenteric artery. Following abdominal incision to exposethe bowel, lower GI bleeding was caused by incising the antimesenteric border of the small bowel wall. Initialangiography was performed, and this was followed by Tc-99m pertechnetate IA scintigarphy. Tc-99m RBC IAscintigraphy involved two patients who had undergone selective mesenteric arterial catheterization for theevaluation of acute lower GI bleeding. RESULTS: Ten rabbits, bleeding at a mean rate of 0.7g/min, were studied.IA scintigraphy was superior to angiography in four cases and equal in six. The sensitivity of angiography was40%(4/10), and IA scintigraphy 80%(8/10). In one patient, Tc-99m RBC was administered directly into the superiormesenteric artery and ulcer bleeding in the transverse colon was identified. Prior to conventional angiography,the bleeding had been occult. In a second patient, in whom angiography had revealed a hypervascular mass,selective injection of Tc-99m RBC into the superior mesenteric artery revealed tumor(leiomyoma) bleeding in thejejunum. CONCLUSION: Selective IA scintigraphy was valuable for detecting intestinal bleeding, occult duringconventional studies and may be useful for detecting acute bleeding at the time of negative angiography.
