1.Detection of Mycobacterium tuberculosis in Sputum by using Polymerase Chain Reaction.
Korean Journal of Clinical Microbiology 1999;2(2):144-151
BACKGROUND: The recently developed nucleic acid amplification methods may provide us with very sensitive, specific and rapid tests for the detection of M. tuberculosis. So the aim of this study was to compare the commercial Amplicor M. tuberculosis kit and our in-house polymerase chain reaction (PCR) with the conventional culture and direct AFB staining method. Materials and METHODS: Among the total of 2,340 clinical specimens, 1,314 sputum samples were tested for the presence of M. tuberculosis by Amplicor PCR and 1,026 sputum samples were tested by in-house PCR performing with resin matrix preparation and DNA extraction, synthesized primer pair, detection using agarose gel electrophoresis. RESULTS: One hundred-seventeen specimens were positive by Amplicor PCR, 105 were positive by in-house PCR, 185 were positive by culture. The sensitivity of the Amplicor PCR for all of the specimens and for smear-positive and smear-negative specimens was 92.9%, 97.9% and 88.2%, respectively after discrepant analysis. The sensitivity of the in-house PCR for all of the specimens and for smear-positive and smear-negative specimens was 80.0%, 93.6% and 65.5%, respectively after discrepant analysis. The specificity of the Amplicor PCR and in-house PCR for all of the specimens was 97.9% and 99.0%, respectively. CONCLUSIONS: Amplicor PCR was more sensitive than in-house PCR, but there was another problems such as high false positive rate and high cost. So PCR may certainly become very useful in microbiological laboratories if PCR method is selected according to the laboratory conditions.

2.The effects of health education on health promoting lifestyle of college students.
Journal of Korean Academy of Adult Nursing 1997;9(1):70-85
This study has been undertaken in order to 1) test the effect of health education on the performance of health promoting lifestyle, self efficacy, control and perceived health status in college students, 2) assess whether pretreatment level of self-efficacy, control, and perceived health status predict post-treatment health promoting lifestyle, 3) assess whether pre-to post-treatment changes in self-efficacy, control, and perceived health status predict post-treatment health promoting lifestyle, and 4) examine the correlation between changes in subscales of health promoting lifestyle. One-group pretest-posttest design was used. Fifty eight college students at T college in T city were studied. They attended a health education, which is composed of 13 sessions(one session per week, 130 minutes per one session). This study was conducted from August 26 to December 2. The instrument used for this study included a survey of general characteristics, self-efficacy, control, perceived health status and health promoting behavior. Analysis of data was done by use of mean, percentage, paired t-test, pearson correlation coefficient and stepwise regression. The results of this study are summarized as follows : 1) The average item score for the health promoting lifestyle was low at 2.301. In the sub-categories, the highest degree of performance was interpersonal support(2.87), following self actualization, nutrition, stress management, exercise, and the lowest degree was health responsibility(1.67). Female students had lowest degree in exercise subscale(1.48). A significant correlation between self-efficacy and control, self-efficacy and perceived health status, self-efficacy and health promoting lifestyle, control and health promoting lifestyle. Self-efficacy was the highest factor predicting health promoting lifestyle of college students(38.31%). 2) No significant difference among total health promoting lifestyle and subcategories of health promoting lifestyle. Self-efficacy was increased after health education than that of before education(T=2.33, P=.023). Control was decreased after education than that of before education(T=-2.03, P=.046). 3) Pretreatment self-efficacy, control, and health status did not predict post-treatment health promoting lifestyle. 4) Pre-to post-treatment changes in self-efficacy predicted post-treatment stress management subscore. 5) Pre-to post-treatment changes in control predicted post-treatment self actualization and exercise subscale. A significant correlation between changes in self-actualization and changes in exercise, changes in self-actualization and changes in nutrition, changes in health responsibility and changes in exercise, changes in exercise and changes in interpersonal support, changes in exercise and changes in stress management, changes in nutrition and changes in interpersonal support, and changes in interpersonal support and changes in stress management.

4.Stratum Corneum Ceramides and Free Amino Acids in the Lesion of Scaly Hand Eczema.
Korean Journal of Dermatology 2000;38(7):893-901
BACKGROUND: Lipids of horny layer forming multiple lamellar structure in the intercellular space acts as a skin barrier having a primary protective function and keeps softness and flexibility of the skin by absorbing and maintaining moistures. Among the intercellular lipids, ceramides mainly contribute to this important role. In xerotic eczema, atopic dermatitis, psoriasis, ichthyosis, and experimentally induced scaly lesion showing dryness and scales, the amount of ceramides is decreased or distribution of ceramide is changed. In addition to lipids, free amino acids, a component of NMFs, serve as a water retainer and are decreased in ichthyosis or experimentally induced scaly lesion. Hand eczema has dry and scaly lesion showing impaired skin barrier and low water content. So, changes of ceramides or free amino acids can be considered in the lesion of hand eczema. OBJECTIVE: The purpose of this study was to confirm the relationship between the development of hand eczema and changes of ceramides or free amino acids. METHOD: The lipids and free amino acids in scales from lesion of hand eczema were analyzed by using high performance thin layer chromatography and amino acid analyzer. RESULTS: Amounts of total lipids extracted were 0.63+/-0.33 microgram/cm2 in hand eczema and 0.44+/-0.26 microgram/cm2 in control. There was no difference between the two groups. Cholesterol sulfate, glucosyl ceramide, cholesterol, triglyceride, sterol ester, and n-alkane showed no difference between hand eczema and control. But ceramides were significantly decreased in hand eczema(11.0+/-5.5%) compared with control(21.4+/-8.0%)(p<0.05). Especially, ceramide type IV was significantly decreased in hand eczema (6.6+/-5.3%) compared with control(15.6+/-6.2%)(p<0.05) but ceramide type III in hand eczema did not differ from control. Amounts of total free amino acids in 10mg of scale were 10.4+/-3.1nmol in hand eczema and 9.5+/-3.0nmol in control. There was no significant difference between the two groups. CONCLUSION: Dry skin and scales in hand eczema are related to the decrease of total amount of ceramides and ceramide type IV than amino acids in horny layer. To clarify the exact pathogenesis of hand eczema, further investigations on all types of ceramides and their defect in the process on biosynthesis of ceramides will be necessary.

BACKGROUND: The diagnosis of tuberculosis has been based on the detection of tubercle bacilli by acid-fast stain of smear or cultures, and recently the serologic diagnosis of tuberculosis has been provided a means of sensitive and specific detection of Mycobacterium tuberculosis. We evaluated the utility of enzyme immunoassay using determiner Tuberculosis Glicolipids(TBGL) antibody kit(Kyowa Medex Co. Ltd, Japan) to detect anti-TBGL antibody for diagnosis of pulmonary tuberculosis. METHODS: Anti-TBGL antibody assay was performed to the form 44 patients with active pulmonary tuberculosis(17 patients with smear positive, 7 patients with only culture positive, 20 patients with clinically active tuberculosis) and 80 controls (30 healthy controls, 24 patients with non-tuberculous respiratory diseases, 26 patients with inactive tuberculosis). We compared the sensitivity and specificity of anti-TBGL antibody with culture and AFB stain. RESULTS: Anti-TBGL antibodies were detected in 16 of 17(94%) smear positive patients, 4 of 7 patients with only culture positive and 16 of 20(80%) smear negative patients who had been clinically diagnosed as active pulmonary tuberculosis. Nine(35%) out of 26 patients with inactive tuberculosis, one(4%) out of 24 patients with non-tuberculous respiratory diseases and no one of healthy control had a positive antibody response. Overall sensitivity, specificity of the anti-TBGL antibody assay were 82%, 88%, respectively and sensitivities and specificities of culture and AFB smear 64%, 97%, and 49%, 100%, respectively. Anti-TBGL antibody titers in patients with active tuberculosis were significantly higher than control grup(P<0.05). Conclusions : The anti-TBGL antibody assay was sensitive, rapid and convenient. This assay will be useful as a tool for the diagnosis of tuberculosis in combination with other conventional methods.

It has suggested that a significant proportion of intraepithelial lesion of the cervix may be related to the influence of human papillomaviurs (HPV). Its etiological relation with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma has recently been proposed. The 131 cases of CIN and 6 condyloma acuminata were stained by immunoperoxidase technique for HPV anigen. The results are as follows: The 18 cases (13.1%) exhibited positive staining, localized in nuclei of koilocytotic cells confined to superficial and intermediate layer of epithelium. HPV antigen was found in 1 case (16.7) of 6 condyloma acuminata, 4 cases (12.5%) of 32 mild dysplasia, 3 cases (13.6%) of 22 moderate dysplasia, 2 cases (14.3%) of 14 severe dysplasia and 8 cases (12.7%) of 63 carcinoma in situ. In the positive cases of mild and moderate dysplasia, HPV antigen was localized directly within the lesion, while those cases of severe dysplaia and carcinoma in situ contained positive cells in areas of mild or moderate dysplasia adjacent to the lesion. Of three distinct morphologic patterns, flat type was most common and papillary type was least. Histologically condylomatous lesions were present in 67 cases (51.1%) out of 131 cases of CIN. The histological and cytological feature encountered most frequently was koilocytotic arypia. Other main histological features are bi- or multinucleation, exocytosis of inflammatory cells, acanthosis, mitotic figures, dyskeratosis and epithelial pearl. On the cervical smear, the evidence of condyloma was proved in 50.0%. Cytologically in the condyloma with high degree of CIN, the nuclear atypia was so prominent that the differentiation from dysplasia or carcinoma in situ was very difficult, although the chromatin appeared somewhat smudged. The mean age of 18 cases was 42.4 years which is older than previous study. The results of this study provide common association with HPV and CIN and add great weight to the suggestion that the infection with HPV plays an important part in genesis of cervical cancer.

Journal of the Korean Pediatric Society 1994;37(10):1333-1339
Exercise induced asthma (EIA) is defined as acute, reversible, usually self-limiting airway obstruction which develop after strenous exercise in patients with asthma. EIA is a bigger problem in children than adults due to more active and smaller airways which obstruct more easily when bronchospasm develops. The exercise elicited many change in pulmonary function of asthmatic children. These change could be measured by measurements of PEFR, FEV1, FVC, or SRaw. The propose of this study is to determine the changes and sensitivity of different pulmonary function test in asthmatic children. 37 asthmatic children exercised on free running and pulmonary function tests were performed before and every 5 minutes during 15 minutes after exercise. The results were as follows. 1) In 37 asthmatic children, EIA developed in 23 children (62%) and did not developed in 14 children (38%). The difference in sex, height, weight, total eosinophil count, serum IgF and test between EIA and Non-EIA were not significant (P>0.05). 2) In EIA group, %PEFR was changed from 109.56% to 83.56%, But in Non-EIA group, %PEFR was not changed before and after exercise loading test. 3) In EIA group, %FEV1 was changed from 90.91% to 74.87%. But in Non-EIA group, %FEV1 was not changed before and after exercise loading test. 4) In EIA group, %FVC changed from 91.83% to 75.35%. But in Non-EIA group, %FVC was not change before and after exercise loading test. 5) There was significant difference in pre-exercise specific airway resistance between EIA (6.7+/-1.7) and normal children (5.8+/-2.2)(p<0.05). In EIA group, %SRaw was changed from 115.7% to 161.2%. But in Non-EIA group, %SRaw was not changed before and after exercise loading test. 6) During the post-exercise observation period, increasement of SRaw was greater than changes in any other pulmonary function test. SRaw is the most sensitive test for the ditection of exercise induced airway obstruction is asthmatic children.

Fungi have been recognized as a significant cause of external otitis and it may be the primary pathogen or be part of a mixed infection. In the immunocompromised host, fungus is capable of producing infection in inner ear or middle ear. Otomycoses are most frequently caused by Aspergillus spp. and Candida sap. There are few reports that Aspergillus species other than A. fumigatus, A. niger and f. flavus have caused chronic otitis media. We report two cases of chronic otitis media caused by Aspergillus ferrous in Korea. One case is a 7-year-old girl who had recurrent serous otorrhea and otalgia for 4 years, was reattended otolaryngology clinics with otorrhea of 3 days durations and another is a 6-year-old girl who had serous otorrhea for 2 months and 3 day fever, was attended otolaryngology clinics with them. Microscopic appearance and colony morphology from ear discharge cultures revealed A. ferrous. The infection responded well to topical ketoconazole therapy. This report should help to raise medical personnel's awareness of such human opportunistic fungal ear infections.
