Mucinous tumor are cystic tumors with loculus lined with mucin-secreting epithelium constitute approximately 8-10% of primary epithelial ovarian tumors. Of all mucinous neoplasms, 75-85% are benign. It is often reach very large size particularly with the benign counterpart being reported on occasion to have exceed 100 lbs. Malignancy develops in 5-10% of benign mucinous cysts. About 15-20% of neoplasms are bilateral. We experienced a huge ovarian mucinous tumor of 155 ㎏. measured 42 × 30 × 28 ㎝ in size, and the volume of cystic contents was about 10 L in a nulligravida 36-year-old woman. Pathologic diagnosis was moderately differentiated mucinous cystadenocarcinoma of right ovary. So, we presented with a brief review of literatures.

The purpose of this study was to estimate the proportion of user charges out of total treatment costs and to investigate the occuring status of the charge of non-benefit service. The data were collected from 6 hospitals in 3 cities (Seoul 2, Incheon 3, Shihung 1), which containing 1,752 discharge-bills of discharged patients insured by health insurance. The data were analyzed after standardization of the items of non-benefit services. The result are as follows; 1. the average percent of the cost-sharing of discharged patients was 38.1%(benefit : 15.5%, non-benefit : 22.6%) and the proportion of the cost-sharing due to non-benefit services was greater than that due to benefit services. 2. The occurrence rate and the occurred number of non-benefit services were different among hospitals and showed characteristic occurrence rate in individual hospitals. 3. In acute appendicitis, the characteristics of the occurrence rate and the occurred number of non-benefit services by individual hospitals was similar to those of hospitals. It suggest that the hospitals intentionally applied non-benefit item to patients in order to increase their profit. These findings suggest that the burden of cost-sharing is still high especially due to non-benefit services, so it is necessary to extend the coverage of insurance benefits and to develop management system for the appliance of non-benefit services. Regarding the discharge-bill, all service charges should be included in the bill.

This work carried out the removal of aniline by wet oxidation in aqueous solutions like a industrial wastewater using Ozone. UV, and Ozone - UV. The main features of this experiment are as follows : the aniline was decomposed by OH and HO2 radicals which produced from the reaction of water with UV and Ozone, when the Ozone and Ozone - UV used the aniline was decomposed completely. The decomposition of aniline was very fast reaction and the reaction times were 10 min. and 20 min. in case of for Ozone and Ozone-UV respectively. Assumed simplified reaction mechanism from the aniline oxidation model, and then we are calculated the theoretical reaction rate constants by computer simulation, and then compared with experimental data. We suggest that this simulation program is applicable to estimate of the aniline decaying concentration and removal efficiency of aniline - contaminated wastewater.

A retrospective study of clinical feature, tumor location, histopathologic finding, operative results and prognosis were carried out in a series of 55 patients who were performed operation between January 1, 1989 and December 31, 1998 at the Department of Neurosurgery of Soonchunhyang University Hospital. The results were summurized as followings 1) The incidence of spinal cord tumors varies with the age of affected patients who are 2 to 75 years of age. Peak incidence occurs in the 5th & 7th decade of life, and the ratio of male to female was 1.2 : 1. 2) The most common histopathologic type was neurinoma in 23 cases(41.9%), and the rests were metastatic tumor in 12 cases(21.8%), meningioma in 8 cases(14.6%), lipoma in 3 cases(5.5%), astrocytoma in 2 cases(3.6%), ependymoma in 2 cases(3.6%). 3) The tumors were located most frequently in the thoracic area(22 cases, 40.0%), in the intradural extramedullary space(30 cases, 54.5%), extradural space(19 cases, 34.5%), intramedullary space(5 cases, 9.1%), and intradural and extradural space(1 case, 1.8%) according to location into spinal canal. 4) The most common initial clinical feature was pain in 20 cases(36.4%), and the rest were motor disturbance(15 cases, 27.3%), motor & sensory disturbance(10 cases, 18.2%), sensory disturbance(6 cases, 10.9%), sphincter disturbance(2 cases, 3.6%), no symptom(2 cases, 3.6%). In neurologic status on admission, 30 cases(54.5%) were motor disturbance and the rest were radiculopathy or sensory changes(21 cases, 38.2%), sphincter disturbance(1 case, 1.8%), no symptom(3 cases, 5.5%). 5) In radiologic study, there were abnormal finding in 21 cases of plain X-rays among 37cases. The entire 20 cases of myelography showed subarachnoid blockade, complete or incomplete. The magnetic resonance imaging, regard as the most accurate diagnostic method, showed the exact location of the tumor and the relationship of the tumor with the adjacent anatomical structure in entire 29 cases. 6) The total removal was possible in 36 cases(65.5%), subtotal removal was in 17 cases(30.9%) and biopsy was in 2 cases(3.6%). Postoperative 31 cases(56.3%) were recovery or improved, 21 cases(38.2%) were stationary state, and 3 cases(5.5%) were progression of clinical symptom and neurologic status. Nineteen cases(90.5%) among 21 cases of preoperative radiculopathy group were recovery or improvement but only 11 cases(36.7%) among 30 cases of preoperative motor weakness group were recovery or improvement, that was statistically significance(p 0.01). Pathologically, 26 cases among 31 cases of neurinoma and meningioma were postoperative recovery or improved, but only 1 case(6.3%) among 16 cases of metastatic tumor, astrocytoma and ependymoma were recovery. Also, that was statistically significance(p <0.05). Postoperative complication were in 5 cases(9.1%) that were postoperative hematoma, pneumonia, pulmonary edema, and spinal cord infarction. According to the above results, preoperative neurologic status and histopathologic finding were important factor of postoperative outcome in spinal cord tumor.

A muscular calf is esthetically unappealing in Asian women. Treatment by liposuction alone has poroven to be difficult due to a small amount of fat. We established a new method of transecting half of the gastrocnemius tendon in order to improve the contour of the calf. Thirty-five patients were operated on during the past 3 years. The medial or lateral half of the gastrocnemius tendon was cut using an endoscopic-guided 3M AGEE blade through a 1cm-sized incision. The portion of the muscle above the site of the transection was elevated from the underlying soleus muscles. We checked the calf circumference and evaluated the clinical results at 6 months postoperatively. An average 10% reduction in calf circumfernce was measured, showing a significant esthetic improvement. There were no significant changes in gait analysis or in the Cybex test. There were no specific complications related to the procedure. Through our clinical experience in 35 cases, we were able to prove that tenotomy is a effective, simple and easy method without severe morbidity.

A high performance liquid chromatographic method using tetrathiocyanatocobaltate [Ⅱ] ion as a complexation reagent was developed for the determination of berberine in crude drugs, pharmaceutical preparations and serum of rats. When berberine is added to a solution containing Co[Ⅱ] and excess thiocyanate ion, a green 1,2-dichloroethane-soluble substance precipitates. This green substance was transferred to 1,2-dichloroethane and injected to HPLC system for determination of berberine. Retention time(flow rate : 1.0 ml/min) was approximately 6.5min. on a μ-bondapak C_18 column(3.9 x 300mm) with an eluent of acetonitrile : methanol : H_2 H(2.5 : 2.5 : 5, containing KH_2 PO_4 2g/L), and detection wavelength was 340 nm. Standard plots were linear for 1 - 500 ppm of berberine soln.(0.1 - 50 ppm as berberine-TCR complex 1,2-dichloroethane soln.). The average recovery of berberine standard soluton was 99.98% and coefficients of variation for berberine content in standard soln, coptidis rhizoma, phellodendri cortex, pharmaceutical preparation, serum were found to be less than 0.59%, 3.26% 1.05%, 1.23%, 1.17% respectively. This method is rapid and precise.

최우성,김원유,최동원,신윤학,김진영 대한골절학회 2003 대한골절학회지 Vol.16 No.2

목적 : 원위 요골 골절에 대해 전방 도달법을 이용한 관혈적 정복 및 수장부 T자형 금속판 내고정술의 방사선학적 및 임상적 결과를 분석하여 문헌 고찰과 함께 보고하고자 한다. 대상 및 방법 : 도수 정복이 되지 않았거나, 심한 분쇄 골절로 인해 도수 정복 상태가 유지되지 못했거나, 부적절한 관절면의 정복 등의 이유로 원위 전완부 전방 도달법을 이용한 관혈적 정복 및 수장부 T자형 금속판을 이용한 내고정술을 시행 후 최소 1년 이상 추시 관찰이 가능하였던 19예를 대상으로, 수술 전 후의 방사선학적인 평가와 최종 추시시의 기능적 평가를 Green과 O'Brein의 방법을 이용하여 평가하였다. 결과 : 수술 직후 모든 예에서 관절면의 해부학적 정복을 얻을 수 있었다. 방사선학적 결과에서 요골 관절면의 요골 길이는 수술 전 평균 8.8 ㎜ (±4.8 ㎜)에서 수술 후11 ㎜ (±3 ㎜)로, 요골 경사각은 평균 15˚ (±5.7˚)에서 20˚ (±5˚)로, 전방 경사는 평균 -11˚ (±13˚)에서 7˚ (±4˚)로, 척골 양성 변이는 평균 4 ㎜ (±3 ㎜)에서 0 ㎜ (±1 ㎜)로 향상되었으며, 기능적 결과에 있어서는 우수 9예, 양호 7예, 보통 2예, 불량 1예 이었다. 추시 중 초기 수상이 심하였던 1 예에서는 정복의 소실과 함께 장 무지 굴건의 파열이 초래하였다. 결론 : 원위 요골 골절의 수술적 치료에서 일부 제한된 범위에서만 적응증이 되었던 수장부 금속판 내고정술로 방사선학적 측면과 기능적인 측면에서도 만족할 만한 결과를 얻었으며, 초기 분쇄 골절이 심할 경우에는 정복의 소실을 예방하기 위하여 외고정기를 부수적으로 장착하는 것이 좋을 것으로 생각된다. Purpose : To analyze the radiologic and clinical results of open reduction and volar plating through anterior approach for distal radius fracture. Materials and Methods : We retrospectively analysed that 19 distal radius fracture, which would not be reduced by closed reduction or too comminuted to maintain reduction or articular surface incongruency, were treated by open reduction and volar plating through anterior approach. The results were evaluated by preoperative and immediate postoperative radiographics and clinical results were analysed using Green and O'Brien scoring system at final follow up. Results : All cases achieved anatomical articular surface reduction postoperatively. In terms of radiologic analysis, mean radial length (8.8 ㎜±4.8 ㎜ vs. 11 ㎜±3 ㎜), radial inclination (15˚±5.7˚ vs. 20˚±5˚), volar tilt (-11˚±13˚ vs. 7˚±4˚) and ulnar plus variant (4 ㎜±3 ㎜ vs. 0 ㎜±1 ㎜) were improved. The clinical evaluation revealed 9 excellent cases, 7 good cases, 2 fair cases and I poor case. The reduction loss and flexor pollicis longus rupture was occurred in one patient, who had severely displaced comminute fracture in initial injury. Conclusion : Using volar plating, authors gain good radiologic and clinical results. But, additional external fixation is recommended to prevent further collapse in severly comminuted fractures.

Foodservice at elementary schools has been povided nation-wide. It is predictable that foodborne diseases would increase continuously. Formation of a counterplan is urgently needed. This study was designed to identify the stage which contains the critical control points (CCPs) for the microbiological management of HACCP(Hazard Analysis Critical Control Point) at the foodservice provided at elementary schools. Foodservice places at four elementary schools in Seoul were sampled and the overall hygiene of cooking, utensils and equipment, employees, and environment by season were examined. The results showed that the number of bacteria in overall samples was increased and that E. coli, Salmonella and Staphylococcus by biochemical test emerged in more diverse samples in summer than in spring. Particularly, the number of aerial bacteria in summer was three-fold greater than that in either spring or winter. E. coli 0157 was not detected, although Salmonella was identified by PCR analysis in the meat Knives, chopping boards, waste bins and meat dish at elementary school foodservice. According to this data, cross-contamination should be managed in the stage of mixing up the ingredients with improper equipments and insanitary treatments. Thus, the establishment of SSOP (Sanitation Standard Operating Procedures) and GMP (Good Manufacturing Practice) at elementary school foodservice is stringently required, along with sanitation education for workers and employees as CCPs.

김지나;홍정연;신원선 한양대학교 2009 韓國 生活 科學 硏究 Vol.28 No.2

In this study, using three different cooking facilities(Vitamin+, conventional non-electric steamer, boiling jar), the effect of cooking method on the degradation of vitamin C will be investigated. Three cooking methods were applied to examine their effects on vitamin C residue. For each batch, 5 vegetables and dumpling were steamed by using Vitamin+, 6 conventionally steamed, 6 boiled and 6 remains raw as a control group. For cabbage, broccoli, spinach, bean sprout, vegetable dumpling and potato, the retention values of vitamin C were 53.30%, 73.07%, 69.48%, 83.93%, 84.17% and 12.53% respectively, when cooked by Vitamin+. On the contrast, the retention was 40.05%, 39.34%, 50.09%, 73.24%, 55.63% and 8.85% respectively, when cooked by conventional steam jar. When the vegetables were boiled for 10 min, the retention was 21.83%, 59.43%, 22.08%, 18.24%, 37.28% and 7.38% respectively. Thus, vitamin C retention in vegetables and processed food(dumpling) cooked by Vitamin+ was significantly higher than cooked by other cooking methods. This implies that Vitamin+ steaming can minimize the vitamin C loss for various vegetables and, even processed food during cooking.
