표준균주를 포함한 230여개의 김치유래 젖산균에 대한 균체지방산(FAMEs)을 분석하였다. FAMEs profiles는 Euclidian Distance 17.5에 의해 7개의 Major Cluster와 1개의 Single Cluster로 나뉘어졌다. 이중 A, B, C 및 Cluster는 Leuconostoc속으로 분석되어졌고, F는 Lactobacillus속으로 분석되어졌다. 그리고 E와 G cluster는 두개의 Genus가 혼재되어 나타났으며 보충적인 연구가 필요하다. 앞으로 김치유래 젖산균의 균체지방산 분석결과를 기반으로 한 데이타베이스에 95가지 탄소원을 이용하는 수치분류학적 접근방법 및 Pyrolysis Mass Spectrometry 등의 화학적 분석 방법과 분자친화적 연구를 통한 종합적 분류정보 체계가 갖추어지면 젖산균의 신속, 정확한 동정 및 연구에 활발히 이용되어질 것이다. Two hundreds and thirty lactic acid bacteria, mostly isolated from Kimchi, including type strains were sued for analysis of cellular fatty acids. The 230 test strains were recoverd in 7 major and 1 single clusters defined a Euclidian distance of 17.5. These aggregate taxa were equivalent to the genus Leuconostoc (aggregate group A, B, C and D), and the genera Leuconostoc and Lactobacillus (aggregate group G). It is concluded as evident that FAMEs (Fatty Acid Methyl Esters) profile of cell can be used as a criterion in classification of lactic acid bacterial from kimchi. Additional comparative taxonomic studies need to be carried out on well chosen representative strains to determine the most appropriate methods of value.

The anemometer is one of the sensors that can measure the aircraft speed. This paper describes that the development of the system for measuring the aircraft speed for low-speed, low-height using anemometer. This system can compensate in order to the linearized zone for measuring aircraft speed. The wind tunnel test has been carried out with the hardware of the constand current anemometer and constand temperature anemometer using wheaston bridge circuit. The control Algorithm which selects the data for a linearized zome in a wide range of the wind speeds has been adopted. The system were formed and tested by introducing the mixed algorithmic approach used constant current circuit and constant temperature circuit in order to measure the aircraft speed in a wide range of the wind speed.

Trauma is one of the most common causes of death. Recently, injury severity score(ISS) is widely used to evaluate and classify the patients with multiple injury. Trauma score(TS) was developed as a means of providing rapid accurate assessment of the injured patient. Authors conducted a review of trauma patients who visited the emergency department of YongDong Severance Hospital from September 1992 to August 1993. ISS and TS were collected from comprehensive initial evaluation. The results were as follows : 1) The subjects were 10.2%(2,666 patients) of total 26,202 emergency patients. 2) Male to female ratio was 2.1 : 1. The age distribution was highest under 10 year(24.9%). The mean ISS was 3.5, and the mean ISS increased with ago. 3. Analysis of injury mechanism showed high incidence of traffic accident(35.3%), blunt trauma 25.7%, fall 24.2%, stabbing 10.7%, and others 4.3% in order. 4. The 8.0% of patients were admitted after initial management and their mean Iss was 12.6 mean TS was 15.5. 5. Among admitted traffic accident patients, the mean ISS of passenger T.A., pedestrian T.A. and driver T.A. were 19.0 ±9.9, 14.4 ±10.6, and 11.3 ±7.7 respectively. 6. Among 42 mortality cases, 25 patients were D.O.A. and 17 were expired. The mean ISS of D.O.A. Patients was 30.0; the mean Iss and mean Iss and mean TS of expired patients were 28.3 and 11.8 respectively. 7. The most common cause of death was head trauma(66.7%). 8. By comparing the ISS and TS of admitted and expired patients, mortality occurred above 16 point of ISS. The mortality increased with increasing ISS, but it was influenced by the trauma site and the severity of the particular injury site. Mortality also occurred below 15 point of TS, the mortality increased inversely with TS, and the mortality with TS, and the mortality was high below 13 point (above 40%).

Lupus erythematous panniculitis is a chronic inflammatory disease of subcutaneous fat that occurs in 2-3% of patients with systemic lupus erythematosus. Lupus erythematous panniculitis typically presents with firm, indurated subcutaneous nodules or plaques commonly developed in proximal extremities, trunks, head and neck. Face, breast and upper extremities involvement with lupus erythematous panniculitis has been infrequently reported. We report a case of lupus erythematous panniculitis developed in a 27-year-old female confirmed by histologic features and laboratory findings.

姜?榮,李重根 中央醫學社 1977 中央醫學 Vol.33 No.6

The offending fungal allergens in six hundred twelve cases of korean patients (male 344 cases, female 268 cases) with allergic respiratory diseases such as bronchial asthma and allergic rhinitis were analyzed by the intradermal skirt test with diagnostic standard allergen extracts. The incidence of positive skin test in allergic respiratory diseases were 67.6 % : 66.7% in bronchial asthma, 67.8% in allergic rhinitis and 89. 5% in combined. Cases. In allergic respiratory diseases, the incidence of positive skin tests against one species of fungus was 50.5%, 42.5% against 2^-3 species, 5.8% against 4?6 species, and 1.2%' against 7?9 species respectively. In allergic respiratory diseases, the incidence of the positive skin reactions to fungal extracts were: 27.1% against Candida albicans, 19. 3% against Trichophyton species, 8.7% against Rhizopus nigricans and 7.5% against Fusarium species.

The aim of this study was to estimate the minimum irradiation time for dental composites using a dynamic mechanical analyzer (DMA) and FT-IR. Six commercially available dental composites with A3 shade were tested: Heliomolar RO (Vivadent, Liechtenstein), Charisma (Kulzer, Germany), Herculite XRV Enamel (Kerr, USA), Aelitefil (Bisco, USA), Z100 (3M, USA), and Z250 (3M, USA). Storage modulus was measured by using DMA (StressTech Rheometer, Rheologica Instrument, Sweden) with fast oscillation mode (1 Hz). After disk-type (4 ㎜ ?1 ㎜) samples were irradiated with 500 mW/cm2 for 1, 2, 3, 4, 5, 10, 15, 20, and 30 s, storage modulus was recorded continuously for 60 min. Degree of conversion was also measured using FT-IR spectroscopy (FTS-165, Biorad Win-IR, Perkin-Elmer, USA) at 60 min after irradiation with same curing condition as DMA test. Sample irradiated with 500 mW/cm2 for 120 s was used as a control. The average of results for five specimens was compared using Tukey multiple comparison test (p=0.05) and the minimum irradiation time of composites was determined. The minimum irradiation time to get adequate polymerization was different depending on the dental composites. Both Z100 and Z250 require short irradiation times (5 s) and Charisma requires long irradiation time (15 s).

We desceribe a case of pulmonary capillary hemangiomatosis in a 52-year-old woman with history of hemoptysis. Pulmonary capillary hemangiomatosis is a locally aggressive benign neoplasm of the lung characterized by the presence of numerous cytologically benign thin walled capillary-sized blood vessel proliferating diffusely through the pulmonary interstitium, in and around pulmonary vessels and airway. Pulmonary capillary hemangiomatosis is characterized by a slow progressive clinical course with sign and symptom of pulmonary hypertension, hemoptysis and right heart failure. The cause of capillary hemangimatosis is as yet unknown. Definitive diagnosis can only be made histologically. Complication may occur in the form of necrosis, shunting, inflammatory process, and local compression or obstruction leading to respiratory failure. We experienced a case of pedunculated capillary hemagioma of the bronchus, and report with review of literatures.
