INVERTED MATTRESS SUTURE를 이용한 선천성 이개연골 변형의 교정

하지운,최병욱,서인석 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.1

There are many kinds of congenital auricular deformities but some congenital deformities have no lack or excess of cartilage, which are mild to a moderately constricted ear, cryptotia and Stahl's ear etc. Even if some kinds of surgical treatments, such as cartilage graft, cartilage turn over and cartilage flap were reported for the correction of them but they were comlex and sometimes unsatisfactory. The method of inverted mattress suture to correct the cartilage deformities is not a new method and some authors reported it previously to correct ear cartilage deformities. Authors have tried to correct several kinds of congenital ear deformities, 2 constricted ears, 5 cryptotias, 2 stahl's ears. 1 satyr ear by using of simple inverted cartilage mattress suture and added Z-plasty or V-Y advancement to corrcet the auricular skin in each cases, respectively. The result was promising without recurrences during average 3 months folloe up periods. This method is immediative, simple, easy to perform and a very useful procedure for the correcton of congenital ear auricular cartilage deformities.

정병운,서운교,정지천,한영환 동국대학교 한의학연구소 1999 東國韓醫學硏究所論文集 Vol.7 No.2

韓藥材 중 肺炎의 치료효과가 기대되는 淸熱化痰, 止咳平喘藥을 중심으로 23種의 藥材를 사용하여 肺炎을 유발하는 K. pneumoniae, S. pyogenes 및 S. pneumoniae 세균의 생육을 억제하는 藥材를 탐색하고, 탐색된 藥材의 추출물에 대한 세균의 最小生育抑制濃度를 측정하였다. 韓藥材의 水溶性 추출물 중 黃連, 胡黃蓮, 敗醬, 黃芩이 K. pneumoniae에서, 黃連이 S. pyogenes에 대해서 생육억제 효과가 있었으며, S. pneumoniae에 대한 比較沮止環의 直徑은 黃連, 鳥梅, 五味子, 黃芩이 우수하였으나 黃連 추출물 사용시 병원균 모두에서 生育沮止環의 크기가 가장 크게 나타났으며 對照群로 사용된 大腸菌과 枯草菌에서도 어느 정도의 抗細菌 효과를 볼 수 있었다. 에탄올 추출물에서는 敗醬, 黃芩, 五味子, 鳥梅가 K. pneumoniae 세균의 생육을 억제하였으며, S. pyogenes 세균은 黃連, 五味子, 鳥梅, 馬兜鈴찾, 黃芩에 의하여 생육이 억제되어 黃連은 水溶性 및 에탄올 溶解性 주출물에서 모두 우수한 抗細菌 효과를 보여주고 있다. 각 세균에 대한 最小生育沮止濃度(MIC)는 K. pneumoniae 세균일 경우 黃連 및 黃芩의 水溶性 추출물과 鳥梅 및 敗醬의 에탄올 溶解性 추출물이 유의성을 보였으며, S. pyogenes 세균은 黃連의 水溶性 및 에탄올 溶解性 추출물과 鳥梅의 에탄올 溶解性 추출물, S. pneumoniae 세균은 黃連과 鳥梅의 水溶性 및 에탄올 溶解性 주출물에서 유의성이 나타났다. 이상의 결과를 통하여 黃連, 五味子, 鳥梅, 黃芩, 胡黃蓮, 敗醬의 水溶性 및 에탄올 溶解性 추출물이 肺炎 誘發菌f K. pneumoniae, S. pyogenes, S. pneumoniae에 對하여 우수한 生育抑制 作用을 나타냄을 알 수 있었다. The various oriental herbal medicines, which have usually been used for treatment of reducing fever, purging intense heat and detoxication, were screened to determine the antibacterial activity and the minimal inhibitory concentration against pulmonary disease-causing Klebsiella pneumoniae, Streptococcus pyogenes, and Streptococcus pneumoniae. The results obtained were as follows: 1. Among the 23 oriental medicines tested, the water-soluble extracts of Coptis japonica, Scutellaria baicalensis and Picrorrhiza kurroca showed the antibacterial activity against K. pneumoniae and that of C. japonica against S. pyogenes. The antibacterial activities of C. japonica, Prunus mume, Schizandra chinesis, Scutellaria baicalensis were also found against S. pyogenes. When C. japonica was used, the high antibacterial activity was shown against Bacillus subtilis and other extracts showed a little activity against B. subtilis and E. coli as a control. 2. The ethanol-soluble extracts of Patrinia scabriosaefolia, P. mume, S. baicalensis, S. chinensis showed the antibacterial activity against K. pneumoniae and those of S. baicalensis, C. japonica, S. chinensis P. mume against S. pyogenes and S. pneumoniae. However, those extract showed a little antibacterial activity against B. subttilis and E. coli except for that the extract of C. japonica showed comparatively high growth inhibition of B. subtilis. 3. Among the medicinal herbs tested, the water- and ethanol extracts of C. japonica showed very extcellent antibacterial activity against the pathogenic bacteria and controls. 4. When the water-soluble extracts of C. japonica and S. baicalensis, minimal inhibitory concentrations (MICs) against K. pneumoniae were 10 ㎎/㎖ and 22 ㎎/㎖, respectively. The MICs of the ethanol-soluble extracts of P. mume and P. scabriosaefolia were 5 ㎎/㎖ and 20 ㎎/㎖, respectively. 5. For the MICs against S. pyogenes, C. japonica showed 15 ㎎/㎖ with the water-soluble extract and P. mume and C. japonica with the ethanol-souble extract did 5 ㎎/㎖ and 10 ㎎/㎖, respecitively. 6. For the MICs against S. pneumoniae, C. japonica and P. mume with the water- and ethanol-souble extract showed 5 ㎎/㎖ and 10 ㎎/㎖, respecitively. As a result, the highest antibacterial activity was found in the water- and ethanol-soluble extracts of C. Japonica against pulmonary disease-causing bacteria, K. pneumoniae, S. pyogenes, and S. pneumoniae. Also, the water- and ethanol-soluble extracts of S, chinensis, P. mume, S. baicalensis and P. kurrooa showed high antibacterial activities.

Melanoma B-16 에서 IL-1β 유발 GnT-Ⅲ,ⅴ 활성에 대한 瓜蔞仁 , 黃芩 추출물의 影響

徐雲敎,鄭智天 대한한방종양학회 1999 대한한방종양학회지 Vol.5 No.1

The activity of N-acetylglucosamitnyltransferase(GnT) Ⅲ and V on a Melanoma B-16 was examined after incubation with interleukin 1 (IL-l ). While augumatting cell proliferation, IL-1 resulted in a decrease of GnT-Ⅲ activity and an increase of GnT-V activities. Consist-u with this, Mdamnu B-16 cultured with IL-l showcd increased affinlity to Daturam stramonium latin, which raogfuzes asialo-tri- and asialeo-tetra-antenery N-linked oligosaccharides. These results indicate that IL-1 modulate glycosyloaderse activity and the oligosaccharide sVtuture of target cells. On the omer hand, to investigate whether or not TKM-SG affect GnT-V gene expression in lung metastatic carcinoma, we used RT-PCR methods. TKM-SG treated cell lines showed low leve1s of secretion of GnT-V mRNA transcription·as elucidated by RT-PCR. Thus, with together lower GnT-V acnuty levels in the medium, TKM-SG was highly enative for lung cancer metastasis treatment and it was concluded that the medicine can be used as a potent anti-lung cancer metastasis medidcine.

External lyogels containing prostaglandin E₁ethyl ester(PGE₁-EE), a produrg of prostaglandin E₁(PGE₁) as a therapeutic agent for erectile dysfunction, were formulated to overcome the aqueous instability and enhance the percutaneous absorption. Lyogels of PGE₁-EE were prepared with ethanol (EtOH)/proplyene glycol (PG) cosolvent system as a vehicle, cineol as an enhancer, and hydroxypropylcellusose as a gelling agent. In vitro percutaneous absorption studies were performed to determine the rate of PGE₁ absorption through rat or hairless mouse skin. The permeability of PGE₁-EE lyogel with enhancer was 16-fold greater than that of lyogel without enhancer. Cosolvent produced 9-fold increase in percutaneous absorption. Pharmacodynamic effects of lyogels were evaluated in mature male cats in terms of intracavernosal pressure (ICP). Lyogles containing 0.01% of PGE₁-EE showed higher ICP compared to intraurethral preparation of PGE₁(1%) and enhancer-free control lyogel. The shelf-life (t_(10%) of lyogel at refrigerated condition (4℃) was calculated as 928 days, which is 4.2 times longer than that of control hydrogel. As a result, PGE₁-EE was formulated successfully to a lyogel system with a selective enhancer and cosolvent system for the topical delivery of PGE₁.

강지혜,윤영삼,김상운,성기창,박광재,강병근 한국의료복지시설학회 2006 의료·복지 건축 Vol.12 No.2

The wealth of Korean disability people’s paradigm has developed by the meaning of whole rehabilitation of the small society for acception and protection. Today, that meaning has been changed to make and choose disability people’s future plans by themselves. The CENTER FOR INDEPENDENT LIVING in Korea has been accepted through the American and Japanese’s activity systems with no objection. Following result of the real reserching, because the CENTER FOR INDEPENDENT LIVING in Korea have no legal basement, so there are little support for these centers and no proper rules and check systems. Therefore, we have to make the legal basement of CENTER FOR INDEPENDENT LIVING and separate by each parts of system and to specialize about them. That means, each parts of system have to mark role mode for doing well, and each systems have to develop new programs and services, and to specialize for in Korea. To add, we should have more small CENTER FOR INDEPENDENT LIVING in each area, and the CENTER FOR INDEPENDENT LIVING which are already started should make network system to contact with other centers in society for giving support of proper information.

목적 : 본 연구는 수근관 증후군의 발생위험이 높은 작업형태에 종사하는 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장과 목재소 근로자에서 근전도검사를 이용하여 수근관 증후군의 유병률을 조사하고자 하였다. 방법 : 상지 단순반복작업근로자로서 육류 및 어류 가공 사업장 근로자 69명과 목재소 근로자 17명을 실험군으로, 관리직, 경리, 경비등 상지의 단순반복작업이 없는 근로자 28명을 대조군으로 선정하여, 작업적 및 병력조사, 이학적 검사와 근전도검사를 통해 수근관 증후군의 유병률을 조사하였다. 결과 : 수근관 증후군의 유병률은 육류 및 어류 가공 사업장과 목재소에서 각각 26.09 % (18명)와 29.41 %(5명)로 조사되었으며, 육류 및 어류가공사업장과 목재소 근로자를 '7년 이상과 미만의 작업기간'으로 층화하여 비교한 결과 '상지부위의 통증 호소 유무', 'Visual Analogue Scale(VAS: 총 10점) 4점 이상 여부', 'Tinel teat 양성 유무', 'Phalen test 양성 유무'는 모두 단기 작업근로자군에서 양성의 빈도가 증가되었고 '수근관 증후군 유무'는 장기작업근로자군에서 양성의 빈도가 증가되었다. 결론 : 육류 및 어류 가공 사업장과 목재소의 수근관 증후군 유병률은 각각 26.09 %와 29.41 %로 육류 및 어류 가공 사업장과 목재소는 1996년 OSHA가 지정한 바와 같이 위험한 작업요인이 있는 작업장으로 분류하여 관리되어야 할 것으로 생각된다. Objectives : This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method. Methods : Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS. Results : 18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms (complaint of upper extremities, Visual Analogue Scale ≥4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group(p<0.05). The prevalence of symptoms and signs were higher in short term workers(<7 years), but the prevalence of CTS was higher in long term workers(≥7 years). Conclusions : The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996
