Biodegradable retinal fixation devices obtain mechnical fixation of the retina with desirable chorioretinal scarring and with the potential for local, sustained release of antimetabolites and steroids to inhibit proliferative vitreoretinopathy. We manufactured a biodegradable retinal tack with barb that was designed in order to prevent intrusion from implantation of retinal tacks. This study was carried to evaluate the efficacy for retinal fixation and the capability for sustained release of drugs with a newly designed biodegradable retinal tack Biodegradable retinal tacks were made of polymers of glycolic acids and were designed with barbs in a shape to prevent the disinsertion. Biodegradale retinal tacks are divided into 3 parts, a conical portion that is inserted into the sclera, a cylinder portion that remains in the vitreous, and a neck portion between the pin and the cylinder. The tapered conical end was manufactured to allow easy insertion through the retina and choroid into the sclera. A cylinder portion was manufactured with a tapered angle that fixes firmly into the orifice of 19 gauge spinal needle. A neck portion, 0.4 mm in diameter, was designed to prevent disinsertion from following implantation of retinal tack. The applicator was a 19 gauge spinal needle and its orifice was prepared to 15°angle to accept the tapered cylinder portion of the retinal tack. The retinal tacks, secured in the needles, were passed through the formed vitreous and inserted into the retina, choroid, and sclera and were released by pushing the internal needle, usually within 2-3mm of the medullary ray of the posterior rabbit retina A retinal tack was placed in each of 8 pigmented rabbit eyes. Slit-lamp biomicroscopy, indirect ophthalmoscopy and fundus photography were performed periodically from 1 day to 8 weeks after surgery. Eight eyes were enucleated and studied by light microscopy at 8 weeks. Biomicroscopic evaluation of the animals revealed edemas adjacent to the retinal surfaces immediately after insertion of the biodegradable retinal tacks in all the animals. These edemas disappeared after 1 week. The first noticeable change in the size of retinal tacks was shown after 2weeks. The size of the retinal tacks gradually got smaller, decreasing to about one-half at 4 weeks and about one-third at 8 weeks. All retinal tacks remained in inserted places without any movement for an 8 week period. On light microscopy, epiretinal proliferations were seen to extend into the vitreous cavity. Cellular capsules that lined the inner aspect of the scleral defect caused by tack insertion were found. However the adjacent retina had a normal cytologic appearance and architecture in all specimens. We manufactured a biodegradable retinal tack that is designed to prevent intrusion from implantation of retinal tacks. All biodegradable retinal tacks reduce in size with time, but no retinal tacks extruded from the inserted place. The newly designed biodegradable retinal tack can be used for retinal fixation and may be used as a vehicle for the introduction of pharmacologic agents to prevent the cellular events that promote proliferative vitreoretinopathy.

Responses to chemotherapy correlate with the increased dose of chemotherapeutic agents in some cancers, e.g. breast cancer, Ewing's sarcoma, Hodgkin's disease(HD) and non-Hodgkin's lymphoma(NHL), then for the improvement of the chemotherapy responsiveness, high-dose chemotherapy(HDCT) was proposed. But, it's application was limited due to complications, especially bone marrow suppression. HDCT and succeeding autologous peripheral blood stem cell transplantation(APBSCT) was introduced to overcome this problem. This study was designed to determine the clinical pictures including clinical parameters and the responsiveness of HDCT followed by APBSCT in Hanyang University Hospital. Ten patients were enrolled. They were 8 adults (3 breast cancers, 3 multiple myelomas, 1 HD, 1 NHL) and 2 children (1 acute myelogenous leukemia (AML), 1 neuroblastoma). Mobilization chemocherapy(MCT) followed by Granulocyte Colony Stimulating Factor(G-CSF) was administered to mobilize stem cells from bone marrow to peripheral blood. The stem cells were collected by using CS-3000 and cryopreserved at -196℃ with programmed controlled rate freezer as the mixture with 10% dimethyl sulfoxide(DMSO). HDCT was administered and cryopreserved peripheral stem cells were infused on day 0 as planned. Patients' mean age was 41 years old. After induction chemotherapy three patients achieved complete response and 5 partial response. The median time for bone marrow recovery after MCT was 11.5 days for neutrophil(〉500/㎣) and 4.8 days for platelet(〉20,000/㎣). There were three cases of neutropenic fever and one case of gingivitis. After HDCT with APBSCT, one patient was converted partial response to complete response, and one patient achieved complete response after HDCT without induction chemotherapy. The median time for bone marrow recovery was 12.7 days for neutrophil(〉500/㎣) and 14.7 days for platelet(〉20,000/㎣). Eight patients developed neutropenic fever and required systemic antibiotics. Transfusion was required 1.6 pints for packed red cell and 23.4 pints for platelet concentrates. Toxicity consisted mainly of vomiting, diarrhea, and mucositis which were mild. HDCT with APBSCT can be performed safely with minimal complications. For the evaluation of the exact role of HDCT with APBSCT in malignant diseases, further studies are required as a large scale of patients and lung-term follow up.

The purpose of this study was to investigate the effects of tooth enamel dissolution by commercial beverages. Five kinds of beverages(cola, cider, aquarius, boribori and sunkist orange) were selected for test medium and sixteen of extracted 3rd molar were used for tooth enamel specimens. The acidity of each beverage was determined with pH meter and the concentration of total glucose was checked with Glucose kit and U-V spectrophotometer. The dissolved calcium was determined by Atomic Absoprtion Spectrophotometer and the change of enamel surfaces were observed with Scanning Electron Microscopy(× 400 & × 1,000 magnification). All collected data were analyzed by one-way & two-way ANOVA in SPSS/PC^+ program. The obtained results were as follows: 1. The major containing acid type of cola beverage was phosphoric acid but the other beverages(cider, aquarius, boribori and sunkist) were citric acid. The pH of each beverage was lowest in cola and sport drink, cider, boribori, fruit juice in ascending order(F=205.85, p<0.001), the average pH of 5 kinds of beverage was 2.84 ±0.04, all beverages used in this experiment were low enough to decalcify the tooth enamel. The total glucose concentration of each beverage was 2.74% in aquarius, 2.78% in cider, 3.96% in sunkist, 4.23% in boribori and 4.27% in cola. 2. The average dissolved calcium concentration in 5cc of beverage was 1.54±0.12ppm/5㎖ of HNO_3 in cola, 1.76±0.38ppm in sunkist, 1.90±0.09ppm in boribori, 3.03±0.09ppm in aquarius, 3.59±0.38ppm in cider and the final calcium contents, which is extrated original calcium contents from total calcium contents after 120 minutes were highest in cola(1.27ppm) and aquarius(1.02ppm), cider(0.58ppm), sunkist(0.45ppm), boribori(0.33ppm) in the order(p<0.05). 3. The direct proportional relationship was not found between the degree of surface change on Scanning Electron Microscopy and the amount of dissolved calcium per immersion time. But the more the immerging time was lengthened, the more surface change was observed. The surface change of 120 minutes group was more remarkable than 30 and 60 minutes immerged group in each beverage.

김주옥,김선영,김관형,서지원,박석영,이종진,박성학 대한감염학회 1995 감염 Vol.27 No.4

목적:폐렴, 기관지염, 만성기관지염에서 fluoroquinolone제제로서 항균력이 강하고, 혈중 반감기가 길고, 객담과 조직내 농도가 높은 sparfloxacin의 안전성과 효과를 enoxacin과 비교하기 위해 본 연구를 시행 하였다. 방법:1994년 10월부터 1995년 4월까지 충남대 부속병원과 대전 성모병원에 내원한 폐렴, 급성기관지염, 만성기관지염이 급성으로 악화된 환자 63명을 대조군(32명)(enoxacin 100 mg 1일 3회 경구투여), 실험군(31명)(sparfloxacin 200mg 1일 1회 경구투여)으로 나누어 임상증상, 세균학적 객담 검사, 혈액검사, 실험실내 항균력검사로 그 치료율 및 안전성을 비교하였다. 결과: 1) 임상종합 평가, 세균학적 균소실, 안전성, 유용성에서 두군간에 의미 있는 차이는 없었다. 2) 시험관내 항균력검사상 MIC가 실험군이 대조군보다 현저하게 낮았다.(p<0.05). 3) 경미한 두통, 식욕감퇴, 상복부 불쾌감, 설사등이 대조군 9예, 실험군 7예에서 발생하였고, 검사실 소견상 SGOT 혹은 SGPT 의 일시적 경미한 상승이 대조군 2명, 실험군 3명에서, 혈중 creatinine 상승이 실험군 2명에서 있었으나 경미하였다. 결론:이상의 결과로 sparfloxacin은 폐렴, 급성기관지염, 만성기관지염의 악화에서 하루 한번 투여로 enoxacin 하루 3번 투여와 유사하게 효과적이고 안전하며, 시험관내 항균력이 enoxacin보다 월등히 우수하여 임상에서도 유용하게 사용될수 있을것으로 생각된다. Background: Sparfloxacin, a new oral quinolone, has a broad spectrum, potent antimicrobial activity, prolonged half life, high concentration in sputum. The clinical efficacy and safety of sparfloxacin have been reported by some previous clinical studies performed in Japan. The objectives of this study were to evaluate the clinical and antimicrobial efficacy of this drug in respiratory tract infections compared to those of enoxacin. Methods:We performed an open controlled, randomized study in 63 patients with acute bronchitis, pneumonia, and exacerbation of chronic bronchitis at Chung Nam University hospital and Dae Jeon St. Mary's hospital from October, 1994 to April, 1995. In the control group(n=32), 100 mg enoxacin was administered orally 3 times a day and in the test group(n=31), 200 mg sparfloxacin once a day. Results: The results were as follows; 1) There were no significant differences between the two groups in clinical efficacy, bacteriological finding, and usefulness. 2) Means and SD of MICs were 0.44±0.89 ㎍/ml in the control group, 0.13±0.24 ㎍/ml in the test group. There was a significant difference in MICs between the two groups(p<0.05). 3) Headache, epigastric discomfort, and loss of appetite were observed in 7 cases of the control group and in 9 cases of the test group, and transient elevations of hepatic enzyme in 2 cases of the control group, and in 3 cases of the test group. There was mild elevation of serum creatinine in 2 cases of the test group. Those laboratory abnormalities by therapy might be associated with their underlying diseases. There were no significant adverse effects caused by the drugs Conclusion:In conclusion, sparfloxacin of 200 mg once a day was as effective and well tolerated as enoxacin of 100 mg three times per day in the treatment of respiratory tract infections. Sparfloxacin is more potent antibiotics because MICs of sparfloxacin were very lower than those of enoxacin.

Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

The purpose of this study is to examine students’ perspectives on two online learning formats: pre-recorded video lectures versus video-conferencing. There were 90 participants who took College English courses in a university in Seoul. Participants took TOEIC tests before taking the classes and were divided into two different proficiency level groups: a high-level group and a low-level group. All participants studied English via both pre-recorded video lectures and video-conferencing (Zoom) for the whole semester. Questionnaires were carried out to explore students’ perspectives on both online formats in accordance with their proficiency levels. The findings of the closed-ended questionnaires revealed that significant differences were not found between the low- and high-level groups regardless of the online learning formats. Regarding students’ perspectives about these online English formats, a statistical difference was not found between the two groups. It is worth noting that students did not show any significantly different perspectives concerning online courses regardless of their proficiency levels. As for the open-ended questionnaires, both groups noted various benefits and drawbacks of the current online learning platforms. Also, they provided constructive suggestions for these online learning formats. The results of this study have pedagogical implications for carrying out successful online courses.

A neural network approach has been developed to determine the depth of a surface breaking crack in a steel plate from ultrasonic backscattering data. The network is trained by the use of feedforward three-layered network together with a back-scattering algorithm for error correction. The signal used for crack insonification is a mode converted 70˚ transverse wave. A numerical analysis of back scattered field is carried out based on elastic wave theory, by the use of the boundary element method. The numerical data are calibrated by comparison with experimental data. The numerical analysis provides synthetic data for the training of the network. The training data have been calculated for cracks with specified increments of the crack depth. The performance of the network has been tested on other synthetic data and experimental data which are different form the training data.
