Purpose: The Purpose of this study was to explain the effects of aromatherapy massage on the preoperative anxiety of hemorrhoidectomy patients, and to provide the effective and holistic nursing care to them. Method: The research design was a nonequivalent control group non-synchronized design. The data were collected during the period from November 1 to November 30, 2003 at K-Hospital in Seoul. The subjects were fifty patients who were to have a hemorrhoidectomy under general anesthesia. They were assigned to two groups, 25 subjects to the experimental group and 25 subjects to the control group. The State Anxiety Inventory tool was used to measure state-anxiety on all patients the day before surgery. Systolic and diastolic blood pressure, and pulse rate were measured on the day before surgery and the preoperative period. The experimental group received aromatherapy massage on the hand with lavender oil. Data were analyzed by x^(2) test, independent t-test, paired t-test. Result: 1. Hypothesis 1, that the level of preoperative state-anxiety of the experimental group who received aromatherapy massage would be lower than that of the control group who did not received aromatherapy was supported(p=.047). 2. Hypothesis 2was that the Physiological index of the preoperative anxiety of the experimental group who received aromatherapy would be lower than that of the control group who did not received aromatherapy. The 1st subhypothesis that "the level of the preoperative systolic and diastolic blood pressure of the experimental group would be less than that of the control group" was not supported. Conclusion: Aromatherapy massage can be regarded as a partially effective nursing intervention that relives the preoperative anxiety of surgical patients and stabilizes vital signs.

The purpose of this study is to investigate the effect of training program for tactile sensation on the change of retarded children's stereotype behaviors. The subjects were two five-year-old boy and girl who were autistic retarded children. The training program for tactile sensation was applied among sense integration activities by learning materials of early treatment for autistic children (Kang Ui Hong, Bo In chung and Sang Bok Lee, 1998). As a method, single subject AB design was executed in the periods of foundation, arbitration and maintenance for 38 times and visual analysis was used by observing and recording the frequency of stereotype behaviors. The summary of the results of the study is as follows: First, the training program for tactile sensation for retarded children had an effect on the decrease of frequency of stereotype behaviors regarding behaviors. Second, the training program for tactile sensation for retarded children had an effect on the decrease of frequency of stereotype behaviors regarding language. Third, the training program for tactile sensation for autistic retarded children had a greater effect on the decrease of frequency of stereotype behaviors regarding behaviors than stereotype behaviors regarding language. The suggestions as results of the study are as follows: First, age distribution of the subjects and place in this study was confined to generalization. Therefore, further study of verification on the effect of various age groups and places is needed. Second, further study of the level of stress that stereotype behaviors of retarded children has on the families and the level of stress after the arbitration of training program for tactile sensation is needed actively.

본 연구는 교정환자의 브라켓과 치아 경계부 및 브라켓으로부터 2 mm 이상 떨어진 치아 평활면의 치면세근막에 존재하는 mutaus streptococci의 종 및 생물형에 차이가 있는지를 알아보고자 시행되었다. 조선대학교 치과병원에 내원한 13세 이상 35세 미만의 환자 28명으로부터 브라켓을 장착하고 있는 61개 치아에서 치균세균막을 채취하여 mutans streptococci를 MSB 배지에서 선택적으로 분리한 다음, 이들의 지놈 DNA를 추출하여 dextranase 유전자를 표적으로 하는 중합효소연쇄반응법을 시행하고, 그 증폭물을 Hae Ⅲ로 소화하고, 이를 전기영동하여 제한효소절편길이에 따라 그 종을 식별하였다. 또한 생물형을 조사하기 위하여 생화학적 검사를 실시하였다. 그 결과 브라켓과 치아 경계부 및 브라켓으로부터 2 mm 이상 떨어진 평활면의 치면세균막에 존재하는 mutans streptococci 종은 서로 비슷한 검출 빈도를 보이나 두 곳에 존재하는 mutans streptococci 생물형은 서로 차이가 있는 것으로 나타났다. 향후 브라켓과 치아 경계부 및 치아 평활면의 치면세균막의 mutans streptococci 생물형의 차이와 브라켓 주위의 법랑질 탈회 및 치아우식증 발병과의 상관관계에 대한 연구가 필요하다. The aim of this study was to compare the species and biotypes of mutans streptococci isolated from dental plaques sampled from the interfaces between the bracket and tooth surface and smooth tooth surfaces in orthodontic patients. Dental plaque was collected from the interfaces between brackets and teeth (test group), and from smooth tooth surfaces distant from brackets by more than 2 mm (control group). The dental plaque collected by a sterilized curette was transferred into a vial of 1 X PBS. The sample in the vial was vigorously vortexed for1 min and plated on mitissalivarius bacitracin (MSB) agar plate using cotton tips. The agar plates were incubated at 37℃ in a candle jar for 2 days, and again incubated for 1 more day at anambient temperature. Individual colonies were cultured in TH broth at 37℃ CO₂ incubator. The PCR-RFLP based on dextranase gene was performed for the identification of mutans streptococci at the species-level. For biotyping of mutans streptococci, biochemical tests were performed. There was no significant difference of the species of mutans streptococci isolated from both test and control groups. However, the biotypes of the mutans streptococci isolated from test and control groups were different. These results may offer the basic data to verify the relationship between the mutans streptococci biotype and enamel decalcification or dental caries in orthodontic patients with fixed appliances.

Objectives: To investigate the rate of first-line eradication and the rate of second-line eradication of Helicobacter pylori (H. pylori) from 2001 to 2010 in a single institute in Seoul. Methods: Among the 2,717 patients who received H. pylori eradication treatment from 2001 to 2010 at Ewha Womans University Mokdong Hospital, the medical records of 1,466 patients who satisfied the condition of execution of upper gastrointestinal endoscopy, positive H. pylori eradication results at 6~8 weeks after eradication therapy were reviewed retrospectively. Then the first-line and second-line eradication rates and the eradication rates according to endoscopy findings were also compared. Results: The first-line eradication rate was 77% H. pylori eradication rate for the last 5 years was continuously increasing and no sign of decline was observed even for the whole 10 years. The rates of eradication related to endoscopic findings showed statistical significance (P<0.001) of 79.8% and 70.1% each for peptic ulcer and non-ulcerative gastric diseases, respectively. Conclusion: In this study, no decrease in tendency of first-line eradication rate could be found. In addition, the patients with the non-ulcerative gastric disease seemed to show significantly lower eradication rate. This finding suggests eradication treatment may be affected by the category of gastric diseases, and careful considerations should be taken assessing the effects and needs for the H. pylori eradication treatment.

This comparative study was designed to ascertain whether any differences existed between skeletal class Ⅱ malocclusion (<ANB 5°) and skeletal class Ⅲ malocclusion (<ANB -1°) with respect to the craniofacial morphology and nasopharyngeal area. A total of 121 males and 125 females representing different ages were examined. For the purpose of comparison, each malocclusion was classified by sex, and further subdivided into three different age groups; 12-years-of-age-and-under, 13-to-15-years-of-age, 16-years-of-age-and-over. The conclusions were as follows; 1.There were no differences in the area of bony nasopharynx between both types of malocclusion. 2. As a whole, the areas of adenoids of skeletal class Ⅲ malocclusion tended to be larger than those of skeletal class Ⅲ malocclusion. However, statistically significant differences were found only in the 12-years-of-age-and-under groups of both sex. 3. The areas of nasopharyngeal cavity of skeletal class Ⅲ malocclusion were in general larger than those of skeletal class Ⅱ malocclusion. Statistically significant differences, however, were discovered in the 12-years-of-age-and-under group as well as the 13-to-15-years-of-age group of male. 4. There were significant differences with respect to the rate of area of adenoids to nasopharynx in the 12-years-of-age-and-under groups of both sex and 13-to-15-years-of-age group of male. 5. Cranial base angle showed positive correlation with the depth of nasopharynx and negative correlation with the height of bony nasopharynx. 6. <SNA, <SNB and <ANB were not associated with the size of bony nasopharynx, adenoids and pharyngeal cavity.

The purpose of this study was to investigate the effect of Paecilomyces japonica mycelia(PJM) on pH, titrable acidity and microbiological quality of Jeungpyun(fermented rice cake). Jeungpyun prepared with 0?7% of PJM stored at 5℃ and 20℃ for 4 weeks and 7 days respectively. Before fermentation of Jeungpyun dough, viable cells of total bacterial counts(TBC), yeasts and lactic acid bacteria(LAB) were 6.0~9.8×10^6, 5.3~9.0×10^(6), 5.4~8.5×10^(6) CFU/g, respectively. During the fermentation of dough, viable cells of TBC, yeasts and LAB increased 0.3~0.4 log cycle and pH was decreased whereas acidity incresed as the progress of fermentation. Total viable cells in Jeungpyun before storage were 5.0×10¹ CFU/g. During storage of Jeungpyun, TBC, yeasts and LAB of control group increased 2.6, 2.4, 2.1 log cycle at 5℃ and 4.8, 4.6, 4.5 log cycle at 20℃, respectively, when reached at maximum level. Major microflora of Jeungpyun was composed of yeasts and LAB during fermentation of dough and storage at 5℃ and 20℃. Addition of PJM, inhibited the growth of microorganisms, the changes of pH and titrable acidity of Jeungpyun during storage at both of 5℃ and 20℃. From these results, the addition of PJM extended the shelf-life of Jeungpyun during storage at 5℃ and 20℃.

미강의 세포독성을 hepalclc7, CHO-Ki, MCF-7세포에 대하여 crystal violet 염색법, MTT 방법, 직접세포수 측정법등 3가지 방법으로 평가하였다. Crystal violet 염색법과 MTT 방법을 사용할 경우 직접세포수 측정법에 비하여 모델화합물인 t-BHQ의 세포독성이 과소평가되는 경향을 보였다. 한편 미강 메탄을 추출물의 hepalclc7, CHO-Ki, MCF-7세포에 대한 ED(50)값은 0.125∼0.5㎎/㎖ 범위였다. 미강추출물을 hexane, ethylacetate, n-butanol 및 물로 순차용매분획하였을 때, 세포독성이 높은 성분은 ethylacetate층에 존재하는 것으로 확인되었다. 이를 박층크로마토그래피 방법으로 분리한 결과, Rf-0.73의 단일 때를 얻을 수 있었으며, 여기서 분리한 세포독성은 ED(50)값이 25∼50㎎/㎖으로 매우 독성이 강한 것으로 나타나 임상적학적 유용성을 평가하기 위하여 순수분리하여 구조를 결정하는 연구가 필요할 것으로 판단된다. The cytotoxicity of rice bran extract was investigated using crystal violet assay, MTT assay and direct cell count method for three cell lines including hepalclc7, CHO-Ki, MCF-7 cells. Crystal violet and MTT assays appear to underestimate the cytotoxicity of tert-butyl hydroquinone (t-BHQ), a known inducer of quinone reductase, when compared to direct count method. ED(50) values of methanol extract of rice bran against hepalclc7, CHO-Ki, MCF-7 cells ranged from 0.125 to 0.5㎎/㎖. When rice bran extract was subjected to sequential fractionation with hexane, ethyl acetate, n-butanol, and water, most of cytotoxic activity was recovered in ethyl acetate-soluble fraction. Thin layer chromatography of ethyl acetate layer in n-butanol: propanol: 2N ammonia water(10:60:30) produced a single major band which showed strong cytotoxic effect on the cells, with ED(50) of 25∼50㎍/㎖. Further purification of active component(s) is needed to properly evaluate the clinical usefulness of rice bran. to cereal brans and cereal bran dietary fibres. Mutat Res, 412(3), 323 (1998)
