대구시와 경산시의 하수에서 음이온계 합성세제인 sodium dodecyl sulfate(SDS)와 sodium dodecylbenzene sulfonate(SDBS)를 유일한 탄소원으로 이용하는 균주 289종을 분리하고 이중 합성세제 분해력이 강한, 그람음성 간균으로 운동성인 8균주를 선정하여 그 선정균들의 특성을 조사하였다. 선정균은 40℃ 이상에서는 생육하지 못하였으며 생육 최적 pH는 균주간에 다소 차이가 있었으며 pH 4.0 이하에서는 선정균 모두 생육치 못하였다. 질소원으로는 SDS분해균의 생육에는 potassium nitrate가, SDBS 분해균의 생육에는 soytone이 좋았다. SDS 분해균인 DS-3, 6, 8, 24 및 SDBS 분해균인 BS-7, 8은 세제농도가 5.0% 이상에서도 생육이 가능하였다. 선정균들은 tetracycline에 감수성이 강한 것으로 나타났지만 penicillin에는 강한 내성을 띠는 것으로 나타났고, ??와 ??금속이온은 모든 선정균들의 생육을 억제하는 것으로 나타났다. On purpose to isolate the organisms, which would utilize detergents(sodium dodecyl sulfate, SDS and sodium dodecylbenzene sulfonate, SDBS) as a sole carbon source, from the waste water of Kyungsan and Taegu city 289 strains were isolated. Among them 8 strains, which are gram negative rods with motility and produce strong enzyme to biodegrade the synthetic detergents, were selected. The characteristics of them were investigated as follows, 8 strains were failed to grow above the temperature of 40℃ and below the pH 4.0 even though they have variable optimum pH. Potassium nitrate was very effective for the growth of SDS-biodegradable strains and soytone was effective for the growth of SDBS-biodegradable strains as a sole nitrogen source. Among 8 strains especially DS-3, DS-6, DS-8 and DS-24(SDS-biodegradation strains) and BS-7 and BS-8(SDBS-biodegradation strains) could grow above 5.0% of detergent concentration. All of 8 strains were very sensitive to tetracycline but resistant to penicillin. Selected 8 strains were inhibited by metal ions of ??(0.156mg/㎖) and ??(0.156mg/㎖).

To determine the characteristic double contrast barium enema findings of ileo-cecal and colonic tuberculosis and to make differential diagnosis from other bowel inflammatory disease. Sixty-seven patients confirmed as ileo-cecal and/or colonic-tuberculosis in six hospitals were evaluated retrospectively. The diagnosis was proven by endoscopic biopsy, surgery, and clinical follow up. Nine of 67 patients were excluded because radiologic findings were normal though endocopic biopsy examinations resulted in tuberculosis. Histopathological diagnosis were madein 58 cases as follows: endoscopic biopsy(n=29), operation(n=12), follow up examination(n=14), tissue culture(n=1), laparoscopic biopsy(n=2). There were 30 men and 28 females. The mean age were 36 yrs(range:16-67), 34 patients were in the second and third decade. The distribution of lesions, morphological characteristics, mucosal changes, ulcer shape and depth, associated with other tuberculous lesion, multiplicity were retrospectively analyzed in the findngs of double contrast barim enema. The commonest clinical symptoms were abdominal pain(n=35, 60%) and diarrhea(n=18, 31%). The chest radiography revealed association of pulmonary tuberculosis in 39 cases. Tuberculous lesions of other organs except chest were present in five cases. Double contrast barium enema findings showed a thickening and irregularity of intestinal mucosal fold(n=29, 50%), bowel contraction and/or shortening(n=26, 45%). There were small, nodular, superficial ulcers in the case of ulcer depth less than 2 mm in the depth. As many as 39 cases(67%) in this series had two or more lesions in the intestinal tuberculosis. The involved segment revealed symmetrical feature(n=21, 36%). Inflammatory pseudopolypoid lesions were noted in 30 cases(52%). The ileo-cecal region was involved in 38 cases(66%). The ascending colon(n=25, 43%) was the second commonest site with or without contiguous cecal involvement. Lesions in terminal ileum, ileo-cecal valve, transverse colon, descending colon and appendix were seen in 19, 18, 18, 12 and seven cases, respectively. Among 18 cases of ileo-cecal valve lesions, there were incompetency in nine cases(16%) and wide gapping in four cases(7%). In 14 cases, tuberculous enterocolitis was diagnosed by clinical follow-up and double contrast barium enema study. 12 out of 14 cases, the findings of double contrast barium enema of tuberculous enterocolitis were normalized after anti-tuberculous medication. However, two cases showed more aggravated state than before due to inappropriate treatment. Double contrast barium enema plays an important role in the diagnosis of tuberculous enterocolitis, determines the type, site and extent of the involvement and helps in treatment guide by using sequential studies.

Objective: This study was designed to evaluate the effect of premedication of ramosetron orally disintegrating tablet (ODT), a potent 5-HT3 receptor antagonist, for prophylaxis and treatment of postoperative nausea and vomiting (PONY) undergoing breast cancer surgery using patient controlled analgesia (PCA). Material and Method: 130 women classified ASA physical status Ⅰ-Ⅱ, aged 24-60 yr, undergoing elective breast cancer surgery, were randomized. A standard general anesthetic technique and postoperative PCA using fentanyl and ketorolac were used. Patients were assigned to one of three groups; group A (no prophylactic antiemetics were administered), group B (4 mg of ondansetron ODT was administered 30 minutes before induction), and group C (0.1 mg of ramosetron ODT was administered 30 minutes before induction). Episodes of nausea and vomiting, the use of rescue antiemetics, degree of pain, adverse events, and level of satisfaction were checked during 24 hr after the operation. Results: The overall incidence of PONY during the 24 hours after the operation in group B and C were decreased. The incidence of nausea after 6 hours after the operation and the frequency of the use of rescue antiemetics were significantly lower compared with group A and B. The patients in group C were more satisfied with control of PONY than others. Conclusion: This study results suggest ramosetron ODT was an effective way to prevent PONY in breast cancer surgical patients using PCA.

Background: Many chronic diseases are associated with the lifestyle such as smoking, alcohol drinking and exercise. Attention is increasingly paid on the effect of exercise for the management of chronic disease these days. Objective: The purpose of this study was to evaluate the status of the smoking habit, alcohol drinking and physical exercise of the patients with chronic diseases. Methods: Total 793 persons(normal:422, chronic disease patients:371) in a hospital were questioned regarding the habits of smoking and alcohol drinking, and a practice of physical exercise in 1999. The patients with chronic illness were divided into three groups(Group I included the patients of hypertension and diabetes mellitus. Group II includes respiratory disease and cancer. Group III included liver disease ). The rate of exercise, the rate of smoking cessation and the rate of abstinence were assessed. In logistic regression analysis with each independent variables in each disease groups(I, II and III), odds ratio for the presence of disease was controlled for age and education. Results: The rate of exercise, the rate of smoking cessation and the rate of abstinence was 31.5%, 27.3% and 9.5% in the patients with chronic disease, respectively. In control group, those were 31.5%, 21% and 2.1%, respectively. In logistic regression analysis with exercise as independent variable, odds ratios(95% CI) for age and education were significantly high, with smoking cessation, odds ratio for age was high and with abstinence, odds ratio for disease was high in all disease groups. Conclusion : It was suggested that an effort for proper changes of lifestyle related to disease such as smoking, alcohol drinking and exercise should be intervened in the patients with chronic diseases.

In this study, we evaluated genotoxicity of heavy metals among particulates with Tradescantia-micronucleus (Trad - MCN) assay in the various working environment. In a synthetic fiber factory and a rubber factory, chromium concentration was higher than any other heavy metals. On the other hand, nickel concentration was the highest in a semi-conductor factory. The difference in genotoxicity among the working environment was statistically significant as Trad-MCN frequencies were 4.67±0.35 MCN/100 tetrads (p<0.01) for the synthetic fiber factory, 5.73±0.81 MCN/100 tetrads (p<0.0I) for the rubber factory, and 15.60±2.58 (p< 0.01) (p< 0.001) for the semi-conductor factory. As a result, heavy metals among particulates in the working environment can be considered to have hazardous potential to human health, although they cannot directly induce DNA damage to the workers in the working environments.

Secretory ducts in the pedicel of Cosmos bipinnatus were studied with the light and electron microscope to investigate fine structure of the secretory cells. Secretory ducts were composed with five to twelve cells and secretory cavity. It is thought that secretory ducts were developed as schizogenous type of development, with separation of neighbouring cell walls. We observed characteristic polarity of secretory cells, cytoplasm near the apical pole and vacuoles near basal pole. A group of several tens to hundreds of globular shaped secretory materials were observed in the cytoplasm. We could not observe cell organelles except chloroplast with well developed thylakoids. Eccrine secretion is thought to be the type of secretion in cosmos pedicel. 코스모스 화경의 분비관은 5-12개의 분비세포로 이루어져 있었으며 이생적으로 발달하는 것으로 생각된다. 분비세포의 세포질은 분비내강 쪽으로 모여서 분포하고 있었으며 기저부 쪽에는 액포가 다수 위치하여 분비세포의 세포질 분포는 극성을 나타내고 있었다 분비세포의 분비물질은 구형으로써 수 십 수 백개가 모여서 집단을 이루고 있었으나 분비내강으로 분비된 이후에는 불규칙한 모양을 하고 있었다. 분비세포 내에서는 엽록체를 제외한 다른 세포소기관을 관찰 할 수 없었으며 엽록체에는 thylakoid가 잘 발달되어 있었다. 코스모스 화경의 분비관에서 일어나는 분비기작은 누출상 분비에 의한 것으로 사료된다.

The purpose of this study is to investigate the urban housewives and the level of their consciousness and management in the problems of living environment, and to analize the major factors which make various effects. On the findings of these data, author myself is to inspire the environmental accountability and the role in environment preservation, and to provide the grounding materials, by which housewives are realistically awakened to their new significance in the environment problems in the life area. The period of investigation was a month in august, 1993, and the subject of it was limited to the housewives who were living in Kwang-Ju. the 650 sheets of questionnaires were distributed to them and the 536 sheets of them were used in research materials. The data which was obtained got the frequency percentage and the arithmetic mean by way of SAS, and were analyzed by F-test, Duncan's multiful rangement, Pearson's coefficient analysis and stepwise multiful regression. The major findings is summarized as follows: 1) The average score of housewives consciousness and management behavior on the problems of living environment are 74.14 on the scale of 115 (64.46 on the scale of 100) and 69.80 on the scale of 115 (60.69 on the scale of 100). 2) Housewives'age, education and income, the attitude on the household labor, the satisfaction in the family life and the perceptibility in the time pressure are the variables which have an influence on their consciousness in the problems of the living environment, while their age, education, the satisfaction of the family life and the attitude on the household labor are the variables which have an influence on their management behavior in them. 3) There are relatively a positive correlationship between their consciousness and management behavior in the problems of the living environment. 4) It appears that their management behavior on the problems in the living environment has a major correlationship with the consciousness on them, the education, the income and the attitude on the household labor. Based on the above result, the change of consciousness are required in the problems of the living environment. Accordingly, we should develop enough programs and materials in the environment education, and take the lifelong education and the data development.
