A survey was carried out from August to December 2004 in Pusan, Korea to document the presence of free-living amoeba (FLA), including the genus Acanthamoeba, in both contact lens storage cases and domestic tap water. Acanthamoeba was isolated from 5 (4.2%) in 120 contact lens storage cases. Four house tap water samples from residents, whose contact lens storage cases had been contaminated by Acanthamoeba, were also found to be contaminated with Acanthamoeba. Therefore, the contamination rate of FLA and Acanthamoeba in domestic tap water was investigated in order to examine the role of domestic tap water in Acanthamoeba contamination of contact lens storage cases. FLA and Acanthamoeba were identified in 97 (46.8%) and 16 (7.7%) of the 207 domestic tap water samples, respectively. There were no significant differences between the contamination rates of FLA in tap water according to the filtration plant of origin. No FLA was detected in the tap water directly supplied by the water purification plants. Water storage tanks appear to promote FLA colonization, including Acanthamoeba, in domestic tap water. This increases the risk of Acanthamoeba contamination in contact lens storage cases as well as increasing the risk of Acanthamoeba keratitis.

An appreciation of the normal variation of the Talar Tilt angle under stress roentgenogram on the ankle joint may throw some light on the diagnosis and treatment in an ankle joint injuries. The purpose of this study is to show the normal range of the Talar Tilt angleof the ankle joint under various circumstances and has been to compare the results of each angle. The author have undertaken the neutral ankle mortise view and inversion and eversion stress roentgenogram in all ankles and measured its Talar Tilt angle. The data were based on study of free chosen 50 normal Korean adult male 25 and female 25 respectively. The results were summerized as follows; 1. Talar Tilt angle was O degree in neutral ankle mortise view. 2. In inversion stress roentgenogram, Talar Tilt angle ranged from 0 to 15 degrees, 97% of cases were less than 10 degrees. 3. In eversion stress roentgenogram, Talar Tilt angle ranged from 0 to 7 degrees. 4. In inversion stress roentgenoram, the difference between right and left of same male and female ranged from 0 to 7 degrees. 5. It is very important to check accurately Talar Tilt angle under the same method and same conditions.

The ossification of posterior longitudinal ligament of the spine(OPLL) is newly recongnized clinical entity,although compression of the spinal cord by an OPLL was reported by key as early as in 1839 in Guy's HospitalReport. OPLL was noticeable in lateral tomography as an abnormal dense radiopacity along the posterior margins ofthe vertebral body. Authors retrospectively analysed the diagnostic values and findings of lateral tomography ofthe cervical spine in 11 cases at Kang Nam General Hospital Public Corporation during 1 yr from July 1984 to June1985. The results were as follows; 1. Among suspected 11 cases of OPLL, 9 cases were confiremd as OPLL on lateraltomogram. 2. Age range was 25 years old to 55 years old and more prevalent age was over 5th decades & male wasmore involved than female. 3. Frequent involvement was C2-C5 level and number of vertebral bodies involved was 3.6in average. 4. This ossification developed 4 modes, a continuous type 11%, segmental 33%, mixed type 33%,circumscribed type in 22%. 5. OPLL thickness were from 2mm to 4.5mm and spnal canal narrowing ratio were form 25%to 44% and there were norational relationships between clinical symptom and thicknness of OPLL. 6. On diagnosis ofOPLL, lateral tomography is accurate and recommendable screening study due to easy, noninvasive, indisipensable and less harmful technique, compared to those of myelography or computed tomography.

Control of tuberculosis is threatened by widespread emergence of drug resistance in Mycobacterium tuberculosis. Understanding the molecular basis of resistance might lead to development of novel rapid methods for diagnosing drug resistance. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore, patients who have drug resistance do not convalesce satisfactorily. The molecular mechanism of resistance to rifampin in M. tuberulosis has been elucidated. Substitutions of a limited number of highly conserved amino acids encoded by the rpoB gene are responsible for the ""single-step"" high-level resistance of M. tuberculosis to rifampin. Currently, two genotype-based protocols allow drug test from minimally grown cultured materials: (i)mutation identification by direct sequencing of PCR-amplified material. and (ii)mutation screening by PCR-SSCP. The purpose of this study is to evaluate the usefulness of the both methods. A sample of 75 isolates of M. tuberculosis was studied, and it inculded 36 rifampin-resistant strains and 39 rifampin-sensitive strains by conventional methods. Mutaions were identified in 36 rifampin-resistant isolates but in none of 39 sensitive isolates. All mutations were clustered within a region of 23 amino acids. Both methods allow detection of rifampin resistance in 2 to 3 days and will thus help in the early management of infection by M. tuberculosis.

Most instances of choriocarcinoma of the ovary are gestational in origin. In contrast, nongestational choriocarcinoma of the ovary is an exceedingly rare primary germ cell neoplasm that has worse prognosis than gestational neoplasm. We report a case of pure nongestational choriocarcinoma of the ovary in view of the rarity of its kind. The patient was a 35-year-old Korean unmarried woman who had suffered from vaginal bleeding and feeling of abdominal inflation for two months. The X-ray studies and CT scanning revealed a child head sized cystic mass on the right pelvic cavity and multiple nodular densities in both lung fields and the liver. The mass in pelvic cavity was excised and histologically confirmed to be a nongestational pure choriocarcinoma, arising from the right side ovary.

Control of tuberculosis is threatened by widesread emergence of drug resistant Mycobacterium tuberculosis. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore patients in whom resistance to this drug develop have a poor outlook, particularly if rifampin resistance is associated with resistance to other tuberculosis drugs. The purpose of this study was to detect the mutation in rpoB gene of rifampin resistant M. tuberculosis in Korea and to evaluate the usefulness of the method in clinical aspects. A sample of 80 M. tuberculosis was studied, and it included 40 rifampin resistance isolates and 40 rifampin sensitive isolates by conventional methods. The detection method involved the amplification by polymerase chain reaction (PCR) of the Rif' region and the identification of mutations by single-strand DNA conformation polymorphism analysis (SSCP) of the amplification products (157 bp). Mutation were identified in 39 of 40 rifampin resistant isolates, and in 1 of 40 rifampin sensitive isolates.

PURPOSE: The purpose of this study was to investigate the relationship among nursing work environment, job embeddedness, and turnover intention in order to provide basic data for efficient management of human resources in nursing organizations. METHODS: A cross-sectional, descriptive study design was conducted with 177 nurses who had worked for more than 6 months in five general hospitals on Jeju Island. A self-report questionnaire was used for data collection. RESULTS: About 88% of the participants reported that they were considering a turnover plan because of overload in their jobs and poor salaries. Nursing work environment was significantly related to job embeddedness and turnover intention. Job embeddedness was significantly related to turnover intention. Hierarchical multiple regression analysis showed that factors affecting turnover intention were the organizational embeddedness factors of organization fit and organization sacrifice. CONCLUSION: The results indicate that nurses' turnover intention is associated with nursing work environment and job embeddedness. To reduce nurses' turnover intention and improve nurses' retention, nurse managers should improve the nursing work environment and consider job embeddedness, particularly in relation to the organization fit and sacrifice.

BACKGROUND: Nitric oxide(NO), a multifunctional mediator, is known as a endothelium-derived relaxing factor, a neurotransmitter, and a killer molecule formed by activated immune cells and participates in tissue destruction via apoptosis. In the skin, an increase in apoptotic cells has been desribed in the epidermis in various lichenoid diseases, in response, to ultraviolet radiation, and in neoplasia. OBJECTIVE: The purpose of this study is to investigate whether a positive correlation occurs between iNOS(inducible nitric oxide synthase) expression and apoptosis index in psoriasis vulgaris(PV), lichen planus(LP), and Bowen's disease(BD). METHODS: TUNEL staining and immunohistochemical staining with anti-iNOS antibody were done in paraffin-embedded tissue sections of 4 cases of PV, 4 cases of LP, and 2 cases of BD.
