OBJECTIVE: In Korea, control activities against the endemic malaria due to Plasmodium vivax had been done in 1960s. It is now widely accepted in Republic of Korea that indigenous malaria stopped its endemicity in the mid-1970s. But a vivax malaria case without history of being abroad was recognized in 1993. In addition to this case, 20 cases of indigenous malaria were detected in 1994. And they were progressively increased to about 80 cases in 19%. We report these recently developed cases. METHODS: In a 7-month period between June and December 1995, high fever patient were examined. Patients having a narcotic drug injection or those who had blood transfusion were excluded. Laboratory studies including blood cell count, peripheral blood smear and abdominal sonogaphy were taken. RESULTS: Over 3-month period from July through September 19%, 26 cases of new indigenous malaria were diagnosed. In a blood smear, plasmodium vivax was diagnosed. CONCLUSION: The twentysix new indigenous malaria cases occured. Because all the detected patients had no history of visiting endemic countries, they were not imported cases. Vivax malaria in the present patients can be contracted by infected mosquitos which came across the militarized zone (DMZ). Officially speaking, DMZ is a 4 km wide between the north and south borders, Hut the width is much narrower in many parts. However, we do not have any information on the malaria situation in the north Korea. In order to evaluate a significance of the recent indigenous malario occurrence, a surveillance system should be operated in these areas.

OBJECTIVES: This study was performed to determine the levels of psychosocial distress among clerical public officers to reveal the various related factors. METHODS: A self-administered questionnaires was administered between Dec. 5th, 2005 and Jan. 31st, 2006, to 1,005 individuals in the service of general administration located in Daejeon City. The survey items included the subjects'socio-demographic and job-related characteristics, health-related behavior, degree of job demand, job autonomy, social support in work, type A behavior pattern, locus of control, sense of self-esteem, and psychosocial distress. RESULTS: The results showed that 24.8% of subjects were categorized as high risk stress, 64.9% as latent stress, and 10.3% as normal. The level of psychosocial distress was influenced by various sociodemographic characteristics, such as personality traits (type A behavior pattern, locus of control, selfesteem) and whether performing health-related behavior or not, as well as according to job-related characteristics such as rank in work, job career, job specifications, job demand, job autonomy, social support in work. CONCLUSIONS: The effective strategy for stress reduction among governmental employees requires additional programs focusing on innovated job specifications and managed personality traits.

Turnip yellow mosaic virus (TYMV) is a spherical plant virus that has a single 6.3 kb positive strand RNA as a genome. Previously, we have made the recombinant TYMV construct containing a 0.7 kb eGFP gene or a 1.8 kb GUS gene. The genomic RNAs from these constructs were efficiently encapsidated. To examine in more detail whether size constraint exists for replication and packaging of TYMV, we have inserted into the TY-GUS an extra sequence derived from either eGFP or GUS. We also made a recombinant containing RNA1 sequence of Flock house virus. These TYMV recombinants were introduced into Nicotiana benthamiana leaves by agroinfiltration. Northern blot analysis of the viral RNAs in the agroinfiltrated leaves showed that the genomic RNA band from the recombinant TYMV became weaker as longer sequence was inserted. The result also showed that the efficiency of genomic RNA encapsidation decreased sharply when an extra sequence of 2.2 kb or more was inserted. In contrast, the recombinant subgenomic RNA containing an extra sequence of up to 3.2 kb was efficiently encapsidated. Overall, these results show that size constraint exists for replication and encapsidation of TYMV RNA.

Turnip yellow mosaic virus (TYMV) is a non-enveloped icosahedral virus composed of 20 kDa single coat proteins. In this study, we modified the TYMV coat protein (CP) ORF by inserting an oligonucleotide linker corresponding to T7, HSV, Tat, (Arg)9, or (RxR)4 peptide at the 5'-end of the CP ORF and examined its effect on replication, RNA packaging, and virion assembly. The results showed that the constructs containing (Arg)9 and (RxR)4 sequences were barely capable of replication. The TYMV constructs containing T7 and Tat peptide produced virions that co-migrated with wild-type virions. However, the insertion of T7 and Tat sequences impaired genomic RNA (gRNA) accumulation and packaging, respectively. When only the CP gene was expressed, CPs with (Arg)9 or (RxR)4 successfully produced virus-like particles whose mobility was comparable to that of wild type. In the case of CP having a HSV tag, the virion band was not detected, although a sufficient amount of CP was produced. This indicates that CP with the HSV tag failed to assemble into virions. Overall, the results suggest that TYMV replication, RNA packaging and virion assembly are strongly influenced by the insertion sequence.

Peliosis hepatis is characterized by the presence in the liver of blood-filled cavities, which may or may not be lined with sinusoidal cells. The individual cysts or cavities usually do not exceed several centimeters in diameter. The cysts are typically continuous with adjacent, more normal sinusoids, and they sometimes can be seen in continuity with hepatic venous tributaries. The lesion is usually diagnosed by gross or microscopic examination. When suspected, it can be diagnosed by percutaneous liver biopsy. In the past, peliosis hepatis is primarily associated with wasting diseases, such as tuberculosis, malignancy, and chronic suppurative infection. However, recently peliosis hepatis is seen most commonly in association with the administration of anabolic steroids or HIV infection. We report a case of peliosis hepatis that is diagnosed by peritoneoscopic live biopsy and not associated with known disease.

Endoscopic injection therapy using various different agents(ethanol, polidocanol, epinephrine with and without hypertonic saline, etc.) is considered as the least expensive and effective technique to obtain hemostasis in peptic ulcer bleeding, however most of these agents induce tissue necrosis or degeneration. Theoretically the injection of fibrin glue in peptic ulcer bleeding may be safer than that of other agents, however, to date, there have been no data from randomized clinical trials on the comparison of the efficacies between these agents. To compare the hemostatic efficacy between FG[Beriplast P, Behring, Germany] and HSE[3% saline and epinephrine(1: 10,000)], we conducted a prospective, randomized, clinical trial among one hundred twenty-seven patients with peptic ulcer bleeding from March, 1992 to December, 1993 and in whom a visible vessel or active bleeding was identified.

BACKGROUND: Platelet plays an important role in the pathogenesis of acute coronary syndrome. Platelet glycoprotein IIb III a is the receptor for fibrinogen, and it plays an important role in the platelet aggregation. It was reported that polymorphism of the platelet glycoprotein III a (PlA1/A2) is related to acute coronary syndrome, especially in young patients. The aims of this study is to evaluate the relationship between platelet glycoprotein III a polymorphism and acute coronary syndrome in Koreans. METHOD: We studied total 208 patients (M: F=131 : 77, mean ages : 57.2+/-9.7). Acute coronary group comprised 110 patients, who underwent coronary angiography with the impression of acute myocardial infarction or unstable angina. Normal group comprised 98 patients who had no significant angiographic lesion. Genomic DNA was extracted from peripheral blood. To determine the frequency of PlA1/A2 genotype, polymerase chain reaction (PCR) was done and the product was restricted with Msp I. 3% gel electrophoresis showed Restriction Fragment Length Polymorphism (RFLP). Clinical profile and risk factor were also reviewed. RESULT: One patient in the acute coronary group is PlA1/A2 heterozygote and all the other are PlA1 homozygote. In normal group, all patients are PlA1 homozygote. The genotypic frequency of PlA1/A2 is consistent with the previous study. CONCLUSION: The genotype frequency of platelet glycoprotein III a gene polymorphism in Koreans is different from that of Caucasian. The allele frequencies of platelet glycoprotein III a is not different between acute coronary syndrome patient and normal control group. Platelet glycoprotein III a polymorphism may not be an hereditary risk factor in Koreans.
