Hepatitis G virus (HGV) is a single-strand RNA virus in the Flaviviridae family, it was recently identified from the plasma of a patient with chronic hepatitis. HOV infection may cause acute and chronic liver disease by blood transfusion, drug addicts, hemophilia, and multiple sexual partners. But clinical significance of infectious pathway is still unclear. In this report, we amplified HGV RNA by reverse transcription-PCR (RT-PCR) by primers within the highly conserved 5'-noncoding region (NCR) and used restriction fragment length polymorphism (RFLP) method for the polymorphism analysis of amplified HGV gene. HGV was shown to be present in 7 of 78 (9.0%) from HCV RT-PCR positive serum samples and 5 of 58 (8.6%) from HCV RT-PCR negative serum samples. From the RFLP method HGV divided into four genotypes in 12 positive samples. Therefore, HGV genotype was distributed at least four different types in Korea.

Objective: Cerebral white matter changes (WMCs) and silent brain infarcts (SBIs) are common radiological findings in neurologically asymptomatic elderly people. Their presence is associated with an increased risk of stroke or dementia. Homocysteine (Hcy) can cause atherosclerosis and may thus act as a useful marker of stroke prior to symptom onset. This study aimed to evaluate the utility of Hcy as a surrogate marker for early intervention for stroke in community-dwelling healthy elderly persons with cerebrovascular lesions such as WMCs and SBIs. Methods: We assessed the relationship between the Hcy level and presence of WMCs/SBIs on brain computed tomography (CT) in 554 elderly individuals aged ≥65 years with no history of stroke or dementia. Results: The mean age of the participants was 74.43±7.32 years. Of the 554 patients, 106 (19.1%) had WMCs and/or SBI findings on brain CT. The mean Hcy level was higher in participants with WMCs/SBIs (P=0.001). The WMCs/SBIs group had a significantly greater number of participants with high Hcy levels than the non-WMCs/SBIs group (P<0.001). High Hcy levels (≥12.3 μmol/L) was significantly associated with WMCs and SBIs even after adjusting for age, Korean Mini Mental Status Examination score, education level, and vascular risk factors such as hypertension, diabetes, hyperlipidemia and smoking status. Conclusion: The result of our study suggests that regular monitoring of homocysteine level as a modifiable risk factor may be helpful for predicting the association of cerebrovascular lesions such as WMCs and SBIs for the prevention of future ischemic stroke and cognitive impairment.

The accidents which occurred in the workers with experience of less than one year was 69.4 percent of the total accidents, otherwise, the longer the workers have worked the less accident they have. 8.The most accidents occurred in the shift between 10 to12 o'clock, and 16 to 18 hour. 9. The primary causes of the industrial accidents were found to be collisions, machinery, falling objects and falls. 10. The site of injury by type of industry were quit different, and the major site of injury was finger. 11. The laceration and open injuries of the accidents related to industry were 37.2 percent of the total ceases, and fractures or dislocations were 28.5 percent, and contusions were 6.5% percent. 12. Death rate of industrial accident was 5.0 per 1,000 workers, and those of industry were 47.6 in transportation, 42.8 in construction industry, 24.4 in mine industry, and 2.0 in manufacturing industry.

PURPOSE: The present study purposed to investigate Korean adults health status, smoking perception. and self-efficacy of smoking cessation according to whether smoking or not. METHODS: This study conducted a questionnaire survey of 694 adults at D County in Korea during the period from the 10th of June to the 10th of July 2004. The instruments used for this study were scales on health status, smoking perception and self-efficacy: of smoking cessation. Data was analyzed by frequency and percentage, mean and SD, chi2-test, t-test, ANOVA using SPSS 11.0 program. RESULTS: The subjects of this study were 503 men and 191 women, and 60.8% of the male subjects and 6.8% of the female subjects were smokers. With respect to health status (t=-2.58, p=0.010), smoking perception (t=10.59. p<0.000) and the self-efficacy of smoking cessation (t=-23.04, p<0.000), there were significant differences according to whether smoking or not. CONCLUSIONS: It is necessary to make repeated study to find other variables that affect adults smoking and to develop smoking cessation programs that enhance the self-efficacy of smoking cessation.

BACKGROUND: It is traditiqnally considered that the non-bullous fonn of impetigo is primarily of streptococcal origin and the bullous form is of staphylococcal origin. However, recent reports have shown that Staphylococcus aureus (SA) has become the predominant cauative pathogen of non-bullous impetigo as well as of bullous impetigo. Objective. Our purpose was to evaluate the predominant causativi. pathogen, and to establish a therapeutic guideline for impetigo. METHOD: We described the characteristics of lesions and gerformed bacterial culture and susceptibility tests in patients with impetigo. Patients were treatecl by one of three frequently used antibiotics(erythromycin, cefuroxime, fusidic acid). RESULTS: Of 77 patients, there were 47 cases of crusted type(61.9%), 18 cases of mixed type with crusted and bullous lesiona(23.3%), 7 cases of mixed type with crusted and pustular lesions(9.1%) and 5 cases of bullous type(6.6%). SA was grown from 90.1% af the cases, in 83.1% of cases it was the only organism to be foind and no gowth of streptococcus was faund even in mixed infections. An antimicrobial susceptibility test of 63 strains of SA demonstrated high susceptibility to vancomycin(98.4%), cefuroxime(97.1%), oxacillin(96.4%), cephalothin(95.2%), fusidic acid(91.7%) etc, and high resistance to penicillin(93.7%), gentamicin(90.5%), tobramycin(88.9%) and erythromicin(80.9%). Of 19 patients treated with erythrornycin, 12(63.1% ) showed treatment failure at a weeks, while no treatment failure occured in groups treated with cefuroxime and usidic acid. There were statistically significant differences iri therapeutic effect between cefuroxirne and erythromycin(P=0.005 by two tailedy test), and betweer fusidic acid and erythromycin(P=0.0040. But there was no significant difference between cefuroxime and fusidic acid. CONCLUSION: The predominant pathogen of non-bullous impetigo a well as bullous impetigo was SA which were highly resistant to erythromycin and highly sensitive to efuroxime and fusidic acid. In the clinical response, cefuroxinie and fusidic acid treatment were most effective and erythromycin was inadequate for treatment of impetigo.

BACKGROUND: Ischemic preconditioning reduces the infarct size and the severity of arrhythmia in a post-ischemic reperfused heart although the detailed mechanism is unknown. In the ischemic heart, a large amount of catecholamine is released from the adrenergic nerve terminal and this aggravates cell destruction and arrhythmia. In this study, the possibility for ischemic preconditioning to inhibit the release of endogenous catecholamine from the ischemic heart was tested to investigate the probable cardioprotective mechanism of ischemic preconditioning. METHODS: In the isolated, Langendorff perfused rat hearts, we observed the protective effect of ischemic preconditioning against post-ischemic reperfusion injury, and measured the amount of catecholamine released into coronary effuent. In addition, we observed the effect of catecholamine depletion on reperfusion injury in non-preconditioned and preconditioned hearts. RESULTS: During the reperfusion(20min) after ischemia(30min), the cardiac function was markedly depressed with the development of severe contracture. In the heart preconditioned by three sequential episodes of 5min ischemia and 5min reperfusion, the reperfusion contracture decreased significantly and the cardiac function was almost recovered to normal after 20min reperfusion. The release of lactate dehydrogenase was also decreased in the preconditioned heart. The release of endogenous catecholamine was abruptly increased immediately after the reperfusion and the release was exponentially decreased throughout the reperfusion period. THe pattern of catecholamine release was much different from that of lactate dehydrogenase release. In the preconditioned heart, the release was significantly decreased to about half of that in non-preconditioned t\heart. Endogenous catecholamine depletion by reserpine treatment did not affect the post-ischemic functional recovery in both non-preconditioned and preconditioned hearts. CONCLUSION: It is suggested from these results that ischemic preconditioning inhibis the release of endogenous catecholamine during ischemic period, which may be partly related to cardioporotective effect of preconditioning in ischemic and reperfused heart.
