Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28GST plays important roles in phase II defense system and physiological roles in worm fecundity of C. sinensis.

An outbreak of dermatosis occurred at a machinery manufacture factory in kyongju on Aug 1995. Authors conducted a questionnaire survey among 92 workers in the factory and a dermatologist examined their skin lesions. Authors also collected moths and identified them. The results are as follows; 1. Forty-two cases of dermatosis were identified with attack rate of 45.7%. Attack rate was not different by company, age, sex, educational level and duration of employment. Attack rate was 47.8% among productive workers, 25.0% among clerical workers and 100.0% among patrolmen. 2. Two cases among 42 dermatosis cases and three subjects among 50 non-cases had a history of same dermatosis last year. Four of dermatosis cases had a history of dermatosis among their family members. 3. skin lesions of the cases were scattered or grouped rice-sized erythematous papules or vesicles. Duration of dermatosis from the onset to the time of survey was from one day to more than 30 days. The most frequent site of skin lesion was the arms(81.0%), and it was also observed at the neck(47.6%), abdomen(45.2%), chest(42.9%), legs(38.1%) and back(35.7%). skin lesion was aggravated with sweating(31.0%), after shower(16.7%) and with scratching(l1.9%). 4. Moths were collected and identified as Euproetis subflava(Bremer). Many poisons stings were observed on their wngs which is harmful to human. 5. Contact with moths' wing droppings to two authors on their forearms for provocation resulted in severe immediate pain followed by prolonged pruritus. Erythematous macules quickly appeared and suoceeded by firm wheal-like red papules. Authors thought that the outbreak of dermatosis was brought about by Euproetix subflava(Bremer). Further studies on the factors contributing to the prosperity of the moths in this area are needed.

BACKGROUND: The aim of this study was to evaluate the sensitivity of a clinicians' self-report method for the detection of nosocomial infections (NIs) in comparison with a total surveillance method in a neonatal intensive care unit (NICU). METHODS: Two surveillance methods were concurrently performed in the NICU of a university hospital during 5 months in 2003. Clinicians' self-report surveillance (CSRS) was based on the retrospective verification of monthly reports of positive bacteriologic results by NICU clinicians. Total surveillance (TS) was done prospectively by an infection control nurse based on chart review and laboratory data. RESULTS: One hundred fifty nine patients accounting to 2759 patient-days were included in the study. Twenty-seven NIs among 26 patients were identified by TS. The sensitivity of CSRS compared to TS was 14.8% (4 of 27 NIs). The specificity was 98.5% (131 of 133 non-NIs). Kappa measures of agreement were -0.309. CONCLUSIONS: Our results confirm that the retrospective review of charts and laboratory data by clinicians lacks sensitivity and agreement for the surveillance of nosocomial infections.

BACKGROUND: For the diagnosis of malaria, examination of blood smear slides by light microscopy is used as standard, and commercial kits detecting malarial antibodies and antigens are available, and molecular methods such as polymerase chain reaction (PCR) are used additionally. But, these diagnostic methods can be performed when clinicians request them, so problems of misdiagnosing the patients who are not suspected malaria may be occurred. METHODS: In 42 Korean patients with malaria, the author analyzed the characteristic signals of malaria using granularity (90 degrees depolarized) versus lobularity (90 degrees polarized) graph of Cell-Dyn 4000 (CD4000) automatic hematologic analyzer. And, the author examined the presence of malaria in 421 random samples by CD4000 and Giemsa stain. RESULTS: The usefulness of CD4000 in diagnosing malaria are as follows, 93.0% sensitivity, 99.3% specificity, 93.0% positive-predictive value, and 99.3% negative-predictive value. CONCLUSION: CD4000 automatic hematology analyzer has high diagnostic sensitivity and specificity in diagnosing malaria. Because complete blood count (CBC) is the routine test for most patients, this method has advantage of time and cost effectiveness and can even detect malaria in unsuspected cases.

Authors experienced a case of A3B in a 46-year-old patient with liver cirrhosis and two cases of A3 in her children by family study. A3 subgroups were confirmed by delayed and weak positive with anti-A and anti-A,B, negative in anti-A1 lectin, adsorption-elution test, and family study. We report a family case of A3B and A3 with brief review of literatures.

BACKGROUND: This study was performed to improve the working competencies of novice infection control nurses (ICNs) and thereby prevent healthcare associated infection. We developed and implemented an education program and then evaluated its effectiveness. METHODS: The education program was developed by conducting a literature review and four expert group discussions. The program was implemented twice, and included 3 days of lectures and 1 day of practice in Seoul and Pusan, for 157 ICNs with less than 3 years of experience. The knowledge of the participants before and after the educational program and overall satisfaction were measured. Data were analyzed using the SPSS WIN 18.0 program. RESULTS: The education program consisted of 12 lectures and 2 practices in total. The post-program knowledge score increased to 77.99 compared to 45.91 prior to participating in the program (P<.001). The scores for overall satisfaction, knowledge acquirement, and usefulness in field practice were 9.05, 8.97, and 9.01, respectively. The overall satisfaction was higher for the practice component (9.37) than the lectures (9.00). There were significant differences in surveillance knowledge according to age (F=3.94, P=.021), hospital career (F=3.71, P=.027), hospital type (F=5.36, P=.006), and hospital size (F=6.19, P=.003); and there were significant differences in hand hygiene knowledge according to age (F=4.14, P=.018) and hospital type (F=4.84, P=.009). However, there was no difference in overall satisfaction with the program. CONCLUSION: To enhance working competencies and professionalism, education programs considering the characteristics and needs of the ICNs must be developed. Moreover, professional training courses are needed to nurture ICNs in small hospitals.

A 29 year old man without any noticeable past or familial history presented with left ACA and MCA territorial hemorrhagic infarction after consuming an overdose of disulfiram in a drunken state. This hemorrhagic infarction was thought to be caused by cardiac embolism, which developed following cardiac arrhythmia and cardiac injury induced by O form acceptor reductase associated with disulfiram poisoning.
