Arthroscopic Treatment of Elbow Osteoarthritis and Arthroscopic Ulnar Nerve Decompression

Seok Won Chung 대한견주관절의학회 2016 대한견주관절의학회지 Vol.19 No.4

Although arthroscopic surgery has been used conventionally, it has not been widely adopted yet due to the risks of complications, including nerve damage, technical difficulties, and limited indications. As shown in other joints, however, the use of an arthroscope will gradually increased in the elbow joint (‘Arthroscopy always wins’). Herein, arthroscopic treatments and arthroscopic ulnar nerve decompression will be discussed in cases of elbow osteoarthritis.

생균제로서 가능성 있는 유산균 선별을 위해 발효식품인 동치미로부터 분리된 균주들의 내산성, 내담즙성, 내췌장액성 및 유해균 억제능을 조사하였다. 특히 분리된 균종 중에서 FF-3가 인공위액과 담즙산에 대한 높은 내성을 나타내었을 뿐만 아니라, Salmonella sp.과 Escherichia coli에 대하여 높은 항균 활성을 나타내었다. FF-3유래 박테리오신은 그람 양성 및 음성 세균에서 넓은 항균범위를 나타내었다. 본 연구에서 최종선별된 FF-3 균주들 16s rDNA sequence 동정한 결과 Lactobacillus sp.으로 확인되어 FF-3으로 명명하였다. For selection of lactic acid bacterial for probiotics, we have examined isolated strains from Korean Dongchimi to assess the acid, bile, and pancreatic tolerance and the growth inhibition on the pathogens, Expecially, a kind of isolated strains, FF-3 showed the highest resistancy to both of HCI and bile sale, as well as the highest inhibitory activities against Salmonella sp. and Escherichia coil. Further the bacteriocin of FF-3 showed relatively wide range of inhibition spectrum against gram positive and some gram negative bacterias. By using 16s rDNA sequencing method, FF-3 of the selected lactic acid bacteria were found to be identified as genus Lactobacillus.

文化的 側面에서 본 古代中國의 天道思想

鄭錫元 漢陽大學校 人文科學大學 1998 人文論叢 Vol.28 No.-

For a long time mankind has faced the challenge of survival and one way to meet it was to understand the nature and adapt to it. The first historical evidence of Chinese view of nature appears in Eun-sang(殷商) Dynasty. Therefore, understanding the view of nature of people in Eun-sang(殷商) Dynasty is important in understanding the Chinese 'view of nature'(自然觀) in the Old Chinese period. The more important 'view of nature'(自然觀), however, is that of Chu(周) Dynasty which follows Eun-sang(殷商) Dynasty. The 'view of nature'(自然觀) in Chu(周) Dynasty deeply influences philosophy, literature, arts, life, science as well as Chinese national characters of the modern period. Therefore, this study investigates into the Chinese view of nature in Eun-sang(殷商) Dynasty and Chu(周) Dynasty in order to understand how "Chondokwan" (the view of the way of Heaven.天道觀) has affected the 'Chinese national characters in the modern period.

慶北 漆谷郡 東明 貯水地에서 採集한 淡水魚에서의 吸蟲類 被囊幼蟲 奇生狀의 變動

李元碩,鄭東一,崔東翊 慶北大學校 醫科大學 1991 慶北醫大誌 Vol.32 No.3

1989年 4月부터 同年 9月까지 慶北 漆谷郡 東明貯水池에서 採集되는 各種 淡水魚에서 吸蟲類 被囊幼蟲의 寄生狀을 調査하여 1983年 同貯水池에서 調査한 成績과 比較하였다. 東明貯水池에서 採集된 魚種은 붕어(Carassius carassius), 납지리(Paracheilognathus rhombea), 참붕어(Pseudorasbora parva), 피래미(Zacco platypus)의 4種으로 1983年 少數 採集되었으던 몰개(Gnathopogon atromaculatus)는 採集되지 않았다. 1983年에는 5種의 淡水魚중 2種 즉 몰개와 참붕어에서 2種의 吸蟲類 被囊幼蟲, 肝吸蟲과 Exorchis oviformis 被囊幼蟲을 檢出할 수 있었다. 물개와 참붕어에서의 肝吸蟲 被囊幼蟲의 寄生率은 各各 7.4%와 15.6%였고 魚肉 1g當 被囊幼蟲數로 나타낸 그 寄生程度는 各各 0.1個와 0.2個였고 E.oviformis 被囊幼蟲의 寄生率은 各各 18.5%와 26.7%, 그 寄生程度는 各各 0.2個와 0.4個였다. 그러나 이번 調査에서는 全魚種에서 吸蟲類 被囊幼蟲을 전혀 찾아볼 수 없었다. In order to compare the infestation status with larval trematodes with that in 1983, fresh-water fish were collected in the Tongmyung pond from April to September, 1989, and examined for the presence of the encysted larvae of digenetic trematodes. Four species of fresh-water fish, the crusian carp, Carassius carassius, the flat bitterling. Paracheilognathus rhombea, the southern top-mouthed minnow, Pseudorasbora parva and the pale chub, Zacco platypus, were collected in the pond. Gnathopogon atromaculatus which had been collected in 1983 was not collected in 1989. In 1983, two species of the metacercariae, Clonorchis sinensis and Exorchis oviformis, were demonstrated from G. atromaculatus and P. parva. The incidences of C. sinensis cyst in G. atromaculatus and P. parva were found to be 7.4% and 15.6%. The intensity of infestation, the numbers of metacercariae per gram of flesh, were 0.1 and 0.2, respectively. The incidences of E. oviformis cyst in G. atromaculatus and P. parva were 18.5% and 26.7% with the intensity, 0.2 and 0.4, respectively. However, no larval trematodes was demonstrated from fresh-water fish collected in 1989.

교정 치료 환자에 있어 항균 varnish 처치 전후의 타액 내 Streptococcus mutans 균주의 변화에 관한 연구

남동석,양원식,장영일,서정훈,정종평,김태우 대한치과교정학회 1994 대한치과교정학회지 Vol.24 No.3

Dental caries is one of the most prevalent dental diseases in Korea and its prevention is very important in orthodontic therapy. For the cleansing action of saliva itself and/or tooth-brushing is lowered in patient with fixed orthodontic appliance, oral hygiene of the patient becomes worse, which provides more favorable environment for micro-organisms. Chlorexidine, one of the series of bisguanide, has been reported to be strong antimicrobial agent and very effective on Streptococcus mutans. The purpose of this study is to evaluate the possibility of chlorhexidine as a anticariogenic agent in fixed orthodontic therapy. We used the varnish containing chlorhexidine as a main ingredient for the chemical control of salivary S.mutans in patients with fixed appliance therapy. We applied the varnish containing chlorhexidine on the labial and interproximal surface of the teeth before bonding and banding teeth of our patients(N=20) and compared to control group patients(N=20). Before the application of chlorhexidine varnish and four times periodically after the completion of fixed appliance set-up, we sampled saliva of both group patients and incuvate S.mutans for 24 hours. In the culture study of sampled saliva, counting the number of S.mutans colonies, we founded as follows : 1. In patients with fixed appliance therapy, the risk of dental caries increase when it compared to that of preorthodontic treatment ; The number of salivary S.mutans increase in patient's oral cavity. 2. The experimental agent that contain chlorhexidine is effective to reduce the number of salivary S.mutans. 3. For the effect of this agent is not ever-lasting, periodical application is needed, and additional study for economical interval and number of application is needed.

오원석,이차수,오규실,정원일,정재용,정다히,정규식 한국임상수의학회 2003 한국임상수의학회지 Vol.20 No.4

To investigate the renal effects of enrofloxacin administration on rats induced with dehydration or hyperoxaluria, male rats were treated with enrofloxacin of 50 mg to 500 mg/kg b.w.. The microscopical observations of kidney and urine sediment were carried out in the experimental groups. The result obtained were as follows; The male rats deprived of water for 72 hours and administered with enrofloxacin. As enrofloxacin administration dose was increased, clinical signs such as loss of appetite, depression, weakness, and loss of urine output became more severe. In the histopathological findings, there were hyperemia and hemorrhage in renal cortex, vacuolation and necrosis of renal tubular epithelia, proteinous casts within renal tubules. The male rats were orally administered with sodium oxalate and injected with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, and weakness became more severe. In the histopathological findings, there are hemorrhage of glomeruli and cortical hyperemia, vacuolation and necrosis of tubular epithelia, proteinous casts in renal tubules. In the microscopical findings of urine sediment, there are calcium oxalate crystal (diamond-like type) and magnesium ammonium phosphate crystals (rhomboid). The male rats were intraperitoneally injected with sodium oxalate and administered with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, weakness were more severe. In the histopathological findings, there were hyperemia and hemorrhage in both glomeruli and renal cortex. Severe necrosis of renal tubular epithelia, bluish materials within renal tubules were also found. In the microscopical findings of urine sediment, there were many calcium oxalate crystals. The present results suggest that enrofloxacin has some injurious effects in rats having dehydration or hyperoxaluria, and clinically, we should consider these renal injury effects when we use enrofloxacin in patients accompanied renal disease, dehydration and hyperoxaluria conditions.

김성원,조정석 대구대학교 과학기술연구소 1998 科學技術硏究 Vol.5 No.3

In this study, L-Moments Method which is almost unbiased and has very nearly a normal distribution is used for drought frequency anlysis of monthly precipitation time series among the parameter estimation techniques in Cheju Island basin. and probability distribution model which is used in this analysis is Pearson Type-Ⅲ(PE3), Generalized Extreme Value(GEV), Generalized Normal(GNO), Generalized Pareto(GPA) and 5-Parametric Wakeby(WKB5). FORTRAN Routines for Use with the Moment of L-Moments developed by Dr. Hosking is used for computation process. As a result of this study, the drought duration time within 15 months in Cheju Island basin is fitted by all probability distribution model except for 5-Parametric Wakeby(WKB5), but beyond 15 months, It is appeared that General Logistic(GLO)model is fitted for drought precipitation estimation. but in this study, because it is not coincident with monthly precipitation time series of rainfall gauge stations in Cheju Island Basin, reliability analysis of drought precipitation is degraded now. therefore, for the exact calculation of drought preciptation series, it is required that preciptation data of long-term series and confidence is collected in drought frequency analysis technique.
