OBJECTIVES: This study was performed to investigate the prevalence of nontuberculous mycobacteria (NTM) species and to determine the clinical significance of NTM isolates. METHODS: From January 2003 to July 2011, NTMs were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or reverse blot hybridization assay (REBA). And pulmonary NTM infection was diagnosed by clinical history, underlying disease, radiological and microbiological findings according to the diagnostic criteria of 2007 American Thoracic Society (ATS). RESULTS: Of the 697 AFB culture-positive specimens, NTM was detected in 149 (21.4%) specimens. Among 154 NTM isolates from 149 specimens, M. avium-intracellulare complex (MAC) (48.1%) was the most frequently isolated organisms followed by M. abscessus (13.6%), M. gordonae (9.1%), M. kansasii (8.4%), M. szulgai (3.9%), M. fortuitum complex (3.3%), M. scrofulaceum (2.0%), M. malmoense (1.3%), M. chelonae (1.3%), M. marinum (1.3%), M. genavense (1.3%), M. lentiflavum (1.3%) and M. mucogenicum (0.6%). Among 147NTM isolates from 142 respiratory specimens, 54 NTM isolates (36.7%) were causative organisms in NTM pulmonary infection. CONCLUSIONS: The isolation rate of NTM was 21.4% in clinical specimen, and in some cases NTM species results in pulmonary NTM infection. Because the treatment of pulmonary NTM infection depends on the infecting species, accurate identification and clinical significance of NTM are required for adequate treatment.

Proteomic Analysis of the Increased Proteins in Peroxiredoxin Ⅱ Deficient RBCs

양희영,이태훈 사단법인 한국동물생명공학회 2012 Reproductive & developmental biology Vol.36 No.1

Peroxiredoxin Ⅱ (Prdx Ⅱ; a typical 2-Cys Prdx) has been originally isolated from erythrocytes, and its structure and peroxidase activity have been adequately studied. Prdx Ⅱ has been reported to protect a wide range of cellular environments as antioxidant enzyme, and its dysfunctions may be implicated in a variety of disease states associated with oxidative stress, including cancer and aging-associated pathologies. But, the precise mechanism is still obscure in various aspects of aging containing ovarian aging. Identification and relative quantification of the increased proteins affected by Prdx Ⅱ deficiency may help identify novel signaling mechanisms that are important for oxidative stress-related diseases. To identify the increased proteins in Prdx Ⅱ—/— mice, we performed RBC comparative proteome analysis in membrane fraction and cytosolic fractions by nano-UPLC-MSE shotgun proteomics. We found the increased 86 proteins in membrane (32 proteins) and cytosolic (54 proteins) fractions, and analyzed comparative expression pattern in healthy RBCs of Prdx Ⅱ+/+ mice, healthy RBCs of Prdx Ⅱ—/— mice, and abnormal RBCs of Prdx Ⅱ—/— mice. These proteins belonged to cellular functions related with RBC lifespan maintain, such as cellular morphology and assembly, cell-cell interaction, metabolism, and stress-induced signaling. Moreover, protein networks among the increased proteins were analyzed to associate with various diseases. Taken together, RBC proteome may provide clues to understand the clue about redox-imbalanced diseases.

The purpose of our study was to investigate whether the intrapulpal temperature during cavity preparation of enamel or dentin with Er:YAG laser still remained in range of safety for dental pulp protection when combined with appropriate water flow rate. The effect of different pulse repetition rates at the same pulse energy during ablation was evaluated as well. Caries-free, restoration-free extracted human molar teeth were prepared for the specimen and divided two experimental groups of enamel and dentin. Each group comprised 5 specimens and each of tooth specimens were embedded into a resin block each and measuring probe was placed on the irradiated pulpal walls. For experiments of dentin ablation, enamel layers were prepared to produce dentin specimen with a same dentin thickness of 2 mm. A pulse energy of Er:YAG laser was set to 300 mJ and three different pulse repetition rates of 20 Hz, 15 Hz and 10 Hz were employed. Laser beam was delivered with 3 seconds and less per application over enamel and dentin surfaces constant sized by $3\;mm{\times}2\;mm$ and water spray added during irradiation was a rate of 1.6 ml/min. Temperature change induced by Er:YAG laser irradiation was monitored and recorded While enamel was ablated, there was no significant difference of temperature related to pulse repetition rates(p=0.358) and temperature change at any pulse repetition rate was negligible. Significant statistical difference in temperature changes during cavity preparation in dentin existed among three different pulse groups(p=0.001). While temperature rise was noticeable when the dentinal wall was perforated, actual change of temperature due to Er:YAG laser irradiation was not enough to compromise safety of dental pulp when irradiation was conjugated with appropriate water spray. Conclusively, it can be said that cavity preparation on enamel or dentin with an Er:YAG laser is performed safely without pulp damage if appropriate volume of water is sprayed properly over the irradiated site.

While previous epidemiological studies on temporomandibular disorders (TMD) have been based on a given health center or population sample, no study has been performed on general population of Korea, especially concerning about treatment pattern such as clinician’s specialty involved in TMD treatment, types and amount of prescription medication and cost. This study aimed to investigate magnitude of health visits and treatment patterns for Korean patients with TMD through the computerized database of Health Insurance Review and Assessment Service (HIRAS). Inclusion criteria were all patients registered on the HIRAS database over 3 years' period from 2003 to 2005 and the medical records of patients with TMD as a main diagnosis were extracted. Information collected was as follows; distribution related to gender, age and region and type of hospital the patients visited, treatment duration, clinicians' specialty involved in treatment, cost, types of prescription medication and surgical treatment. The results of this study indicated that 0.15% of the population yearly sought TMD treatment, presenting with increase of incidence over the three years. Most of TMD patients were women (99.8%) and the biggest age group was second and third decades and decreased with age. Seoul and Kyeonggi province presented with higher incidence of TMD compared to the other regions of Korea, which seems to be related with magnitude of population. 56% of TMD patients visited primary care sector and the numbers of treatment visits was the highest in dental clinic (38.4%), followed by orthopedics (28%) and ENT (13.6%) clinics in order. Duration of prescription medication was the longest for anti-inflammatory analgesics, followed by antipsychotic drugs and muscle relaxants. Inpatient care related to TMD was primarily performed in dental hospital compared to medical hospital. Medical database of HIRAS provided comprehensive and vast information on epidemiologic characteristics and treatment patterns for patients seeking TMD treatment, which can be more reliable data to expect medical demand for TMD in condition that accurate diagnosis and standardized treatment is delivered in clinical settings.

양희영,이태훈 사단법인 한국동물생명공학회 2012 Reproductive & developmental biology Vol.36 No.1

Ovarian cancer is the most lethal gynecological malignancy, and specific biomarkers are important needed to improve diagnosis, prognosis, and to forecast and monitor treatment efficiency. There are a lot of pathological factors,including reactive oxygen species (ROS), involved in the process of cancer initiation and progression. The oxidative modification of proteins by ROS is implicated in the etiology or progression of disorders and diseases. In this study,a labeling experiment with the thiol-modifying reagent biotinylated iodoacetamide (BIAM) revealed that a variety of proteins were differentially oxidized between normal and tumor tissues of ovarian cancer patients. To identify cysteine oxidation-sensitive proteins in ovarian cancer patients, we performed comparative analysis by nano-UPLC-MSE shotgun proteomics. We found oxidation-sensitive 22 proteins from 41 peptides containing cysteine oxidation. Using Ingenuity program, these proteins identified were established with canonical network related to cytoskeletal network,cellular organization and maintenance, and metabolism. Among oxidation-sensitive proteins, the modification pattern of Collagen alpha-1(VI) chain (COL6A1) was firstly confirmed between normal and tumor tissues of patients by 2-DE western blotting. This result suggested that COL6A1 might have cysteine oxidative modification in tumor tissue of ovarian cancer patients.

1794년 7월 27일 -‘테르미도르 9일’과 로베스피에르의 실각-

양희영 한국프랑스사학회 2020 프랑스사연구 Vol.- No.42

This article examines the process from the purges of the political factions in the spring of 1794 to the fall of Robespierre on 9 Thermidor, focusing on the choices and actions of the persons involved. In this process, attention is paid to the contingency and improvisation of events rather than to the class conflicts between the bourgeoisie and the sans-culottes or the structural contradictions. The article then examines the political features of the period of the Thermidorian Convention, not as a single period of ‘reaction’ but as a period with a series of different phases. Finally, by introducing studies that question the concept of ‘reaction’ and that reevaluate this period, the article expands our understanding of ‘9 Thermidor’ and the ‘Thermidorian Reaction.’ 이 글은 1794년 봄 당파들의 숙청에서 테르미도르 9일 로베스피에르의 실각에 이르는 과정을 인물들의 선택과 행위를 중심으로 살펴본다. 그 과정에서 부르주아지와 상퀼로트의 계급적 갈등이나 구조적 모순보다는 사건들의 우발성과 즉흥성에 주목한다. 이어 테르미도르파 국민공회 시기를 일관된 ‘반동’기가 아니라 동질적이지 않은 몇몇 단계로 이루어진 시기로 보고 이 시기의 정치적 특성을 검토한다. 마지막으로 ‘반동’이라는 개념에 의문을 제기하고 이 시기를 새롭게 평가하는 연구들을 소개함으로써 ‘테르미도르 9일’과 ‘테르미도르 반동’에 대한 이해를 확장하고자 한다.
