Objectives Aim of this study was to evaluate the clinical use and the efficacy of Frialit-2 implant system. Experimental Methods Fifty nine patients received placement of Frilalit-2 implants(137 implants) in their maxillary anterior and posterior sites(40 and 97 implants). Intraoral & clinical examination, chart review and radiographs were taken from each patient. Results 1. The total implant survival rate was 92.7% after a mean follow-up period of 19.9 months. 2. The implant survival rate placed in anterior region was 97.5%. 3. The implant survival rate placed in posterior region was 90.7%. 4. The implant survival rate placed in atrophic posterior maxilla with advanced technique (GBR, Sinus elevation) was 87.2%. 5. The implant survival rate placed in type N(D4) bone was 82%, while 95.7% in type III (D3), and 100% in type II(D2) bone. 6. Most of the failed implants(7 of 10) were removed during the maintenance stage after prosthodontic treatment. Conclusion It was concluded that Frialit-2 implant could be used satisfactorily in the esthetic anterior region, but the use in the posterior region, especially with poor bone quality and quantity, further studies are needed.

직장암의 치료에 있어서 골반부위에 대한 수술후 방사선치료의 역할을 검중하기 위하여 1979년 2월부터 1980년 6월사이에 치료를 닫은 modified Astler-Coiler병기 B2+3, C1, 및 C2+3의 직장암 환자189명에 대한후향적 분석조사를 시행하였다. B2+3병기의 환자는 47명이었으며, Cl 병기는 17명, 그리고 C2+3병기는 125명이었다. 근치적 수술로 41명이 전방절제술을, 143명이 복부회음절제술을, 그리고 5명은 골반장기적출술을 시행받았다. 전체환자군의 5년 생존율 및 5년 무병생존율은 각각 $45.3\%$ 및 $44.1\%$였다. 각 병기별 5년 생존율은 B2+3에서 $63.4\%$, Cl에서 $62.4\%$, C2+3에서 $37.2\%$로서 이는 통계적으로 유의한 차이를 보였으며 (p<0.005), 5년 무병생존율은 B2+3에서 $55.7\%$, Cl에서 $65.7\%$, C2+3에서 $36.4\%$로서 이것도 역시 통계적으로 유의한 차이를 보여 (p<0.01) 병기가생존율 및 무병생존율에 있어 중요한 예후인자임을 알 수 있다. 재발시 가장 많이 침범되는 장기는 간이었으며, 그 다음으로는 폐 및 회음부였다. 전방절제술을 시행받은 환자군에서 복부회음절제술을 시 행받은 환자군보다 보다 좋은 무병생존율을 보였고 방사선에 의한 장합병증의 위험 이 더 높았다. 수술후 방사선치료로 국소재발억제에는 좋은 효과가 있었으나 진행된 병기에서 주로 문제가 되는 원격전이의 발생은 예방하지 못하였다.

Background: Extracorporeal life support (ECLS) can be applied in brain-dead donors for organ perfusion before donation, thereby expanding the donor pool. The aim of this study was to examine the benefits and early clinical outcomes of ECLS for organ preservation. Methods: Between June 2012 and April 2017, 9 patients received ECLS with therapeutic intent or for organ preservation. The following data were collected: demographics, purpose and duration of ECLS, cause of death, dose of vasoactive drugs, and need for temporary dialysis before organ retrieval. The early clinical outcomes of recipients were studied, as well as survival and graft function at 1 month. Results: ECLS was initiated for extracorporeal cardiopulmonary resuscitation in 5 patients. The other patients needed ECLS due to hemodynamic deterioration during the assessment of brain death. We successfully retrieved 18 kidneys, 7 livers, and 1 heart from 9 donors. All organs were transplanted and none were discarded. Only 1 case of delayed kidney graft function was noted, and all 26 recipients were discharged without any significant complications. Conclusion: The benefits of protecting the vital organs of donors is significant, and ECLS for organ preservation can be widely used in the transplantation field.

A clinical analysis was performed on 48 cases with mitral stenosis who received open mitral commissurotomy from December 1983 to June 1991 at the Department of Thoracic & Cardiovascular Surgery, Chungnam National University Hospital. Fifteen patients were men and 33 were women. the mean age was 35.6 years with the range of 16 to 61 years. The distribution of preoperative NYHA Functional Classes was as follows; class II, 25 patients; class III, 20 patients; class IV, 3 patients. Three patients had cerebral emboli preoperatively, all of whom were in atrial fibrillation. The preoperative electrocardiographic studies revealed that 32 patients had sinus rhythms and 16 had atrial fibrillations. Twenty-six patients had open mitral commissurotomy alone and 22 patients had additional cardiac procedures. Intraoperatively, there were 6 cases of left atrial thrombosis. There was no perioperative death but early postoperative complications were found in 3 cases. The patients were followed up from 2 to 99 months[mean 33.7 months . There was one case of late unexplained sudden death. There was a case of late postoperative cerebral infarction, 5 cases of mitral restenosis and 3 cases of congestive heart failure and/or arrhythmia. Mitral valve replacements were required in 3 patients.But, it is evident that open mitral commissurotomy has many advantages beyond mitral valve replacement concerning the results of the mitral valve replacement underwent during the same period at the Department of Thoracic & Cardiovascular Surgery, Chungnam National University Hospital.

Ninerty one of Trichoderma spp. were isolated from ginseng growing bed, dead trees and muchroom in Korea from March 1978 to June 1979. Six species were identified as T. hamatum(13 strains), T, roningii(17 strains), T. aureoviride(4 strains), but other six strains(strain No. 111, 125, 127, 130, and 503) unidentified by Rifai's key. The reason which is not identified is as following. According to Rifai's key, phialid, phialospore and colony's colour of four strains (strain No. 125, 126, 127 and 130) are like T. longibrachiatum, but they are different from Rifai's method, because sterile-hypha often appears. the fature of standard strain ATCC no. 13631 T. longibrachiatum is like ster9ile-hypha that is used strains in this experiment. The morphology of strain No.503 is the same as T. hamatum except phialospore. Gnerally, T. hamatum's phialospore is subcylindrical, but strain No. 503 is regular ovoid. Therefore, strain No.503 cannot be identified by Rifai's key. The property, strain No.111's phialid is very irregular $(5{\sim}20{\times}2{\sim}2.5{\mu})$) and its phialospore $(4.0{\sim}6.0{\times}3.0{\sim}4.0{\mu})$) is subcylindrical, is uncomfortable to Rifai's method. The standard strains used in this experiment are 7 kinds of Trichoderma spp. received from ATCC.

Purpose: This study was designed to examine the effects of abdominal meridian(Kyongrak) massage on menstrual cramps and dysmenorrhea. Method: Eighty-five women (of 110 screened) enrolled in this study and were employed full-time with more than 6.0 points(in $0\~10.0$ VAS scale) in menstrual cramps or more than 20 points on the dysmenorrhea scale(range $13\~52$). The forty-two participants in the experimental group received abdominal meridian massage for 5 minutes per day during 6 days from the fifth day before menstruation to the first day of menstruation and the forty-three participants in the control group didn't receive any treatment. Data were collected from June 1st to August 30th, 2003 and analyzed using descriptive statistics, $x^2-test$, and t-test. Result: Menstrual cramps and dysmenorrhea of the experimental group were significantly lower after abdominal meridian massage than those of the control group (p<.001). Conclusion: Abdominal meridian(Kyongrak) massage was very effective for relief of menstrual cramps and dysmenorrhea. Therefore, we suggest that abdominal Kyongrak massage can be a useful nursing intervention for women with menstrual cramps or dysmenorrhea.

The aim of this survey is to investigate the current state of pattern identification, treatment and management on chronic fatigue in the Korean medicine. From May 25, 2017 to June 7, we distributed contents of questionnaires to 17,992 Korean medical doctors via e-mail, and then received answers from 329 people. The surveys were conducted by a specialized research organizations. Researchers were blinded to the participant's personally identifiable information or whether they participated in the investigation. In Korea, almost Korean medicine doctors (94.5%) used pattern identification in the treatment of chronic fatigue patients. The main diagnostic methods were visceral (38.5%), qi-blood-fluid-humor (32.3%), and sasang constitutional pattern identification (14.3%). The high-frequent therapy were herbal medicine (37.0%), acupuncture (27.9%), moxibustion (11.7%), and cupping (8.6%). The primary goals of treatment were Improvement and relaxation of stress condition (18.1%), improvement of quality of life (13.1%), increase of functional vitality (34.0%), and fatigue management (23.3%). The key factors affecting treatment outcomes were the patient's aggressiveness in treatment (23.5%) and his/her lifestyle and environment(22.7%). This study was a pioneering research for chronic fatigue on the aspect of medical service provider in the Korean medicine. We hope that this study can be used as a basis for developing a more appropriate and reasonable practice guidelines for chronic fatigue.

Purpose: Composite neuroendocrine-exocrine carcinomas are malignancies that have two distinct components residing within the same tumor: an adenocarcinomatous portion and a neuroendocrine portion. This is rare in gastric cancers; however, poorly differentiated adenocarcinomas can sometimes reveal evidence of neuroendocrine features (NEF) or be 'mixed endocrine and exocrine carcinomas'. This study aimed to review NEF in gastric adenocarcinoma and to evaluate its prognostic significance. Materials and Methods: We selected 29 patients who were diagnosed with gastric adenocarcinoma with NEF and received gastrectomies at the Department of Surgery, Ajou University Hospital between January 2001 and December 2009. We analyzed the clinicopathologic features of gastric cancer with NEF and the prognosis associated with such tumors. Results: The pathologic result with respect to TNM staging of the gastric cancers with NEF were as follows: 5 cases of T1, 5 cases of T2, 10 cases of T3, and 9 cases of T4. There were 7 cases of N0, 7 cases of N1, 8 cases of N2 and 7 cases of N3. The staging of patients with NEF was higher than that of patients without NEF. Especially tumor lymphovascular invasion rate was 82.8%. The overall survival of patients with gastric cancer characterized by NEF was 73.8 months. Conclusions: Positive NEF status might be correlated with clinicopathologic parameters such as a high stage and high frequency of regional lymph node metastasis.
