Esophageal perforation is one of the most grave prognostic problems among thoracic and general surgical emergencies which necessitate urgent operative measures. In Korea,there are still many persons ingesting lye for suicidal attempt and thoracic surgeons in Korea have more chances to deal with lye burned esophagus with or without instrumental perforation than those in Western countries. Main cause of esophageal perforation in Korea is instrumental perforation in patients with lye stricture of the esophagus during diagnostic endoscopy or therapeutic bouginage. Other causes are corrosion of the esophagus due to ingestion of caustic agents, pathologic perforation, surgical trauma, stab wound and spontaneous rupture of the esophagus in our series. Therapeutic measures are various,and depend on duration of perforation, severity of its complications, pathology of perforated portion of the esophagus and degrees of inflammation at the point of perforation. The most important therapeutic measures are prevention of this grave condition during esophagoscopy, bouginage and surgical procedures on lungs and mediastinal structures and to make early diagnosis with prompt therapeutic measures. During the period of January, 1959, to December, 1971, the authors experienced 65 cases ofesophageal perforation including acquired esophagorespiratory fistula at Dept. of Chest Surgery, the National Medical Center in Seoul, and obtained following results in the series. 1. Female were 35 cases, and peak age incidence was 2nd and 3rd decades of life. 2. Among 65 cases, 43 were corrosive esophagitis or benign stricture of the esophagus due to caustic agents, 7 were patients with esophageal cancer. and there were 5 cases of esophageal perforation developed after pneumonectomy or pleuropneumonectomy. 3. Causes of perforation are instrumental perforation in 45, acute corrosion in 7, pathologic perforation in 7, surgical trauma in 3, stab wound in 2 cases, and one spontaneous rupture of the esophagus. 4. Most frequent sites of esophageal perforation were upper and mid thoracic esophagus, and 8 were cases with cervical esophageal perforation. 5. Complications of esophageal perforation were mediastinitis in 42, empyema or pneumothorax in 35, esophagorespiratory fistula in 12, retroperitoneal fistula or abscess in 5,pneumoperitoneum in 3, and localized peritonitis in 1 case. 6. Cases with malignant esophagorespiratory fistula were only 3 in the series which is predominant cause of acquired esophagorespiratory fistula in Western countries. 7. Various therapeutic measures were applied with mortality rate of 27.7% in the series. 8. In usual cases early treatment gave better prognosis, and least mortality rate in cases with perforation in mid thoracic esophagus. 9. Main causes of death were respiratory complications,acute hemorrhage with asphyxia, and septic complications. 10. Esophageal perforation developed after pneumonectomy gave more difficult therapeutic problems which were solved in only 1 among 5 cases.

Impaired fasting glucose (IFG) is one of significant risk factors of developing diabetes. The persons with IFG are, thus, an important target group for primary prevention of diabetes. It is well known that plasma homocysteine concentration may be increased in poor folate nutritional status. Elevated level of plasma homocysteine is considered as a marker of enhanced oxidative stress. In addition, the protective effect against oxidative stress may be diminished in poor antioxidative nutrient status as vitamin C. It is, therefore, important to maintain adequate nutritional status of folate and vitamin C in the patients with type 2 diabetes or IFG. This study was performed to determine the effects of supplementation of folic acid or vitamin C on plasma concentrations of homocysteine, oxidized LDL, and lipids and on the activity of plasma anti-oxidative enzyme in patients with IFG. A total of 97 patients with IFG were participated voluntarily with written consents. They were divided into one of the four experimental groups; Control (C), Folatesupplemented (F), Ascorbate-supplemented (A), and Folate plus ascorbate-supplemented (FA). The subjects in C were taken placebo, those in F were supplemented 1 mg of folate, those in A were received 1,000 mg of vitamin C, and those in FA were given 1 mg of folate plus 1,000 mg of vitamin C daily for 4 weeks. No change in plasma concentrations of vitamin C, lipids, and oxidized LDL and the activity of GSH-Px were observed in vitamin C-supplemented group (A + FA) and folate-supplemented group (F + FA) compared to the placebo group (C + A). Only the folate-supplemented group (F + FA) had significantly increased average serum folate concentration and lowered plasma homocysteine concentration compared to the placebo group (C + A). Thus, it should be recommended the patients with IFG to increase folate intake through diets and, if it is not sufficient, to take folic acid supplements to prevent the development of complications induced by hyperhomocysteinemia as well as oxidative stress.

The purpose of this study is to prepare black ginseng and evaluate its antitumor activity. In order to achieve such aim, 5 year fresh ginsenges were steamed at 95'E for 3 hr in pottery apparatus and dried at $60^{\circ}C$ for 12-36 hr. This process was repeated again nine times in same condition. Among the ginseng saponins in black ginseng, the amount of Ginsenoside $Rg_3$ was examined by HPLC. 10.05 mE of Ginsenoside $Rg_3$ was obtained from 1 g of dried black ginseng prepared. The extract of black ginseng exhibited stronger cytotoxic activity against MCF-1, HT-1080 and Hepa 1C1C7 tumor cell lines in vitro than the extract of red ginseng. Also, the extract of black ginseng exhibited stronger antitumor activity(33%) in BDFl mice bearing Lewis lung carcinoma cells(LLC) than the extract of red ginseng(23%). From these results, it was concluded that Black ginseng had antitumor activity suggesting its application for the prevention and treatment of cancer.

Sarcopenia, a common clinical syndrome in older adults, is defined as decreased muscle mass, strength, and physical performance. Since sarcopenia is associated with the incidence of functional decline, falls, and even mortality in older adults, researchers and health care providers have been keen to accumulate clinical evidence to advocate the screening and prevention of sarcopenia progression in older adults. The factors that may accelerate the loss of muscle mass and function include chronic diseases, inactivity, and deficiency in appropriate nutritional support. Among these, nutritional support is considered an initial step to delay the progression of muscle wasting and improve physical performance in community-dwelling older adults. However, a nationwide study suggested that most Korean older adults do not consume sufficient dietary protein to maintain their muscle mass. Furthermore, considering age-associated anabolic resistance to dietary protein, higher protein intake should be emphasized in older adults than in younger people. To develop a dietary protein recommendation for older adults in Korea, we reviewed the relevant literature, including interventional studies from Korea. From these, we recommend that older adults consume at least 1.2 g of protein per kg of body weight per day (g/kg/day) to delay the progression of muscle wasting. The amount we recommend (1.2 g/kg/day) is 31.4% higher than the previously suggested recommended daily allowance (i.e., 0.91 g/kg/day) for the general population of Korea. Also, evidence to date suggests that the combination of exercise and nutritional support may enhance the beneficial effects of protein intake in older adults in Korea. We found that the current studies are insufficient to build population-based guidelines for older adults, and we call for further researches in Korea.

Background/Aims: To investigate the predictive factors for improvement of atrophic gastritis (AG) and intestinal metaplasia (IM). Materials and Methods: A total of 778 subjects were prospectively enrolled and followed up for 10 years. Histological analysis of AG and IM was performed by using the updated Sydney system. To find the predictive factors for reversibility of AG and IM, 24 factors including genetic polymorphisms and bacterial and environmental factors were analyzed. Results: In all subjects, the predictive factor by multivariate analysis for improvement of both antral and corpus AG was successful eradication. The predictive factors for improvement of antral IM were age and successful eradication. The predictive factor for improvement of corpus IM was successful eradication. In patients with Helicobacter pylori infection, age and cagA were predictive factors for improvement of AG and IM. In patients with H. pylori eradication, monthly income and cagA were predictive factors for improvement of AG and IM. Conclusions: H. pylori eradication is an important predictive factor of regression of AG and IM and would be beneficial for the prevention of intestinal-type gastric cancer. Young age, high income, and cagA are additional predictive factors for improving AG and IM status. Thus, various factors affect the improvement of AG and IM.

Plasmodium vivax exhibits dormant liver-stage parasites, called hypnozoites, which can cause relapse of malaria. The only drug currently used for eliminating hypnozoites is primaquine. The antimalarial properties of primaquine are dependent on the production of oxidized metabolites by the cytochrome P450 isoenzyme 2D6 (CYP2D6). Reduced primaquine metabolism may be related to P. vivax relapses. We describe a case of 4 episodes of recurrence of vivax malaria in a patient with decreased CYP2D6 function. The patient was 52-year-old male with body weight of 52 kg. He received total gastrectomy and splenectomy 7 months before the first episode and was under chemotherapy for the gastric cancer. The first episode occurred in March 2019 and each episode had intervals of 34, 41, and 97 days, respectively. At the first and second episodes, primaquine was administered as 15 mg for 14 days. The primaquine dose was increased with 30 mg for 14 days at the third and fourth episodes. Seven gene sequences of P. vivax were analyzed and revealed totally identical for all the 4 samples. The CYP2D6 genotype was analyzed and intermediate metabolizer phenotype with decreased function was identified.

목적 : 본 연구는 중등도 정도의 오심 및 구토의 발생 위험도를 가지는 복부 방사선치료를 받는 환자들을 대상으로 오심 및 구토에 대한 항구토제의 효과와 부작용 여부를 비교하는 전향적 무작위 임상연구로, 예방 목적으로 항구토제를 사용할 때 현재 통상적으로 많이 처방되는 항구토제인 메토클로프라미드(metoclopramide)에 비하여 온단세트론(Ondansetron; $Zofran^{\circledR}$)을 사용하는 것이 더 나은 효과를 가져오는지 알아보고자 하였다. 대상 및 방법 : 대상 환자의 포함 기준은 병리학적으로 암으로 확진되고 전이성 원인이 아닌 원발 부위에 치료를 받는 환자, 신체수행도가 ECOG 기준으로 2기 이하인 환자, 항암 화학요법이나 방사선치료를 받은 과거력이 없는 환자로 하였다. 1997년 3월부터 1998년 2월까지 총 60명의 환자가 덜 연구에 참여하였다. 내원한 순서에 따라 미리준비된 난수표에 의하여 각각 온단세트론 투약군(O군)과 메토클로프라미드 투약군(M 군)으로 할당하였다. O군의 온단세트론 용량은 8 mg, bid 로 하였고, M군의 메토클로프라미드 용량은 5 mg, tid 로 하였다. 평가 항목은 오심의 정도, 구토 회수, 식욕감소의 정도로 하였다. 환자에게 일일 기록카드를 교부하여 환자의 주관적인 증상인 오심의 정도, 구토의 횟수, 식욕감소의 정도를 기록하도록 하였다. 치료기간을 일주일 간격으로 나누어 각 주별 오심 및 식욕감소의 정도, 평균 구토횟수를 구하였다. 결과 : 본 연구에 참여한 60명의 대상 환자 중 55명의 환자에서 분석이 가능하였다. M군은 28명, O군은 27명이었다. 환자 특성 및 방사선치료에 관한 특성은 연령을 제외하면 차이가 없었다. 연령은 M 군이 $52.9{\pm}11.2$세, O군이 $46.5{\pm}9.6$세로 통계적으로 의미 있는 차이가 있었다. M군에 비해 O군에서 오심의 정도, 구토의 횟수, 식욕감소의 정도의 세 항목 모두 낮은 점수 분포를 보였다. M군의 경우 방사선치료를 시작한 후 5주째 각 항목별 점수가 가장 높은 경향을 보였다. 혼합모형을 이용한 반복측정 자료의 분석 결과 오심의 정도에는 원발암의 종류, 투약군이 의미 있게 영향을 미치는 요소였다. 구토의 횟수에는 성별, 연령, 총선량, 투약군이 의미 있게 영향을 미치는 요소였다. 식욕감소의 정도에는 연령, 투약군이 의미 있게 영향을 미치는 요소였다. 따라서, 투약군이 유일하게 세 가지 항목 모두에 통계적으로 의미 있는 영향을 미치는 요소임을 알 수 있었다. 전 치료기간 동안 양 투약군 모두 약제의 투여로 인한 부작용은 없었으며, 일반혈액검사 및 일반화학검사에서도 이상 소견을 보이지 않았다. 결론 : 연령이 적으면 오심 및 구토의 위험도가 증가하는 점을 고려하면, 양 투약군 간에 연령의 차이가 있었던 점이 통계적 변별력을 저하시켰을 가능성이 있다. 상기 결과를 토대로 본 연구자들은 중등도 정도의 오심 및 구토의 발생 위험도를 가지는 상복부 및 전복부조사를 전통적인 분할조사법을 이용하여 치료하는 경우 현재 흔히 사용되는 항구토제인 메토클로프라미드에 비해 온단세트론이 오심 및 구토, 식욕의 저하 등의 급성 부작용을 더 효과적으로 억제함을 알 수 있었다. 하지만, 온단세트론을 투여하는 경우에도 오심 및 구토가 호전되지 않는 경우도 많이 있으므로 이 부작용을 더욱 경감하기 위한 여러 가지 방안들이 강구되어야 한다고 생각된다.

An Investigation on the usage of herbal clinics in public health centers reveals that 63.7% have received three times or more medical treatments previously and 61.8% have had their illness treated at other medical institutions. In regard to illness 32.1% have had arthritis or muscle aches. 50.9% have taken insurance medication after having had treatments at the public health centers. 66% have assessed acupuncture and moxa cautery the most satisfying. 2. To a question regarding whether herbal health treatment costs higher than that of physician's, the highest response at 31.6% is 'No'. And to a question regarding whether herbal medicines administered at public health centers have more side effects than that of physician's, the highest response at 39.6% is 'No'. 3. To a question regarding whether herbal treatment of public health centers has little effect against acute disease, 48.1% of responses are 'Fair'. To a question regarding whether herbal treatments, when compared with physician's treatments, boost better recovery of patients, 48.1% of responses are 'Fair'. To a question regarding whether herbal medicine is unscientific, when compared with that of western medicine, 38.2% of responses are 'Fair', To a question regarding whether herbal medicine has faster effect on disease than western medicine, 41.0% of responses are 'Fair'. To a question regarding whether herbal medicine is more effective on disease prevention and promotion of health than disease treatment, 38.2% of responses are 'Fair'. And to a question regarding whether the lack of various types of physical therapy devices in herbal medicine, when compared with western medicine causes inconvenience in herbal treatment, 42.0% of responses are 'Fair'. Those responses take up highest portion at each questionnaire. 4. A comparative study between herbal treatments and physician's treatments has also been conducted. To questions regarding which one of the two considering types of disease is the better, responses are the latter accounted for 43.9% against 'Cancer', the latter accounted for 45.3% against 'Endocrine disorders', the former accounted for 30.7% against 'Psychiatric disorders', the latter accounted for 38.2% gainst 'Otolaryngological(ENT) disease', the former accounted for 47.6% against 'Post traumatic stress disorder', and the former accounted for 52.4% against 'Muscle-skeletal disease'. 5. An investigation on frequency of patients' visits via (p<0.05) of subjects show a statistically significant difference. 6. First, an investigation on frequency of reasons of medical treatments reveal that age, occupation, monthly income, and insurance type (p<0.05) of subjects show a statistically significant difference. Secondly, an investigation on frequency of subjects taking insurance medicines after herbal health treatments reveal that monthly income (p<0.05) of subject shows a statistically significant difference. 7. First, an investigation on frequency of a claim that herbal treatments of public health center does not have great effect on acute disease reveals that age, education, and insurance type (p<0.05) of subjects show a statistically significant difference. Secondly, an investigation on frequency of analysis that herbal treatments has faster effect on disease compared with western treatments reveals that education level, religion, monthly income, and insurance type (p<0.05) of subjects show a statistically significant difference. 8. When herbal clinics of public health centers and general herbal medicine institutions are compared, a survey on additional treatments that herbal clinics need the most reveals that education level, monthly income, and insurance type (p<0.05) of subjects show a statistically significant difference. Secondly, an investigation on frequency of subjects who want various forms of herbal medicines reveals that occupation and insurance type (p<0.05) of subjects show a statistically significant difference. Conclusion : In order to improve efficiency of treatments and enhance patient's satisfaction level, this study suggests measures such as providing a differentiated acupuncture treatments as a whole, streamlining an reception procedure, adopting more elaborated computer system for a patient to get proper medical attention, standardizing a treatment duration in order for a maximum result, keeping regular office hours, and optimizing a consultation time for a patient.

본 연구에서는 저염화 사업의 성과 평가 지표의 현황을 분석하고, 델파이 조사를 통하여 저염화 사업 성과 평가지표의 적절성 및 측정방법의 타당도와 수행용이성을 검증하였으며, 그 결과를 요약하면 다음과 같다. 1) 보건소에서 사용하고 있는 저염화 사업 성과 평가지표로는'소금 섭취량', '적정 소금 섭취 인구비율', '싱겁게 먹는 인구 비율', '나트륨 감소법 인지율', '가공식품 구입시 영양표시 정보 확인율', '국의 염도 감소율', '저염 실천하는 모범음식점 증가율', '참가자 만족도', '소금 판매량', '뇌졸중 사망률' 등으로 다양하게 사용하고 있었다. 2) 델파이 조사 결과, 저염화사업 성과 평가지표로서 영양학적 평가지표로는 1일 소금 섭취량이 가장 적절한 것으로 나타났으며, 적정 소금 섭취 인구비율과 싱겁게 먹는 인구 비율 등도 적절한 것으로 나타났다. 보건학적 지표로는 뇌졸중 사망률과 위암사망률이 적절한 것으로 조사되었다. 3) 영양학적 성과 지표 측정방법 중 24시간 소변 수집법이 타당성은 가장 높았으나, 수행용이성은 가장 낮은 것으로 나타났고, 짜게 먹는 식태도 조사 방법이 수행용이성이 가장 높았으며, 짜게 먹는 식행동 조사와 미각판정 방법이 수행용이성이 그 다음으로 높은 것으로 나타났다. 4) 영양학적 성과지표 측정방법의 타당성과 수행용이성을 동시에 고려하기 위하여 이들의 평균 점수에 가중치를 부여하여 순위를 비교하였을 경우 식행동 조사와 식태도 조사가 1, 2순위로 가장 높았고 음식섭취빈도 조사, 미각판정법이 그 다음 순위인 것으로 나타났다. 5) 미각판정법의 신뢰도를 조사한 결과 5개의 시료 농도별 짠맛에 대한 미각판정 결과 남자의 경우 검사자간 판정 결과의 상관계수가 0.774 (p < 0.01)였으며, 여자의 경우도 0.781 (p < 0.01)로 모두 높은 상관성을 보여주었다. 검사자내 신뢰도 조사에서는 짠맛에 대한 미각판정 결과 남자의 경우 첫 번째, 두 번째 판정결과에 대한 상관계수가 0.591 (p < 0.01), 여자의 경우 0.399 (p < 0.01)로 모두 통계학적 유의성을 보여주어 신뢰도가 높은 것으로 나타났다. 본 연구에서 델파이 조사를 1회 실시한 것이 한계점이라할 수 있으나, 이제 막 저염화 사업이 활성화되고 있는 현 시점에서 저염화 사업의 성과 평가지표개발에 대한 중요성을 인식시켰다는데 그 의미를 둘 수 있을 것이다. 또한 본 연구에서 제시된 싱겁게 먹는 인구비율은 적정 소금 섭취 인구비율과 함께 보건소 단위에서 저염화 사업을 할 때 특히 교육 효과를 평가할 수 있는 유용한 지표가 될 수 있을것으로 사료되며, 향후 저염화 사업에서 이 지표의 적합성 여부를 살펴보기 위한 실질적인 적용 연구가 필요할 것이다. 또한 본 연구에서는 제시하지 못하였으나, 미각판정 도구의 농도에 대한 선호도와 강도를 점수화하여 판정과정과 결과 판정을 컴퓨터 프로그램으로 개발함으로써 미각판정법의 표준화를 확보하는 추구 연구가 필요할 것이다.

최근 의공학과 의학기술의 발달로 인간의 수명이 늘어나고 있으며, 이제는 수명에 대한 관심보다는 건강한 노후에 대한 관심에 초점을 맞추어 항노화 산업과 의과학 및 스포츠 과학이 발달하고 있다. 노화의 자연스런운 과정동안 노인들은 면역기능과 생리학적인 기능이 소실되고, 제2형 당뇨병, 고혈압, 골다공증, 골관절염, 심혈관 질환 및 인지감소 등을 경험하게 된다 하지만 규칙적인 운동을 참여할 때 건강한 노후를 맞이할 수 있다. 하지만 이제까지 노인들에게 규칙적인 운동활동의 참여가 건강체력, 정신건강, 인지기능 및 면역력의 변화를 확인하는 연구가 부족한 것으로 여겨진다. 따라서 본 연구는 노인에게서 일상생활도 관리 및 규칙적인 운동활동의 참여가 건강한 노후와 면역력유지에 미치는 효과를 분석하고자 한다. 본 연구를 수행하기 위하여 최근 20여년간 국내,외 이 분야에서 수행된 최신 연구결과들은 펍메드 데이터 베이스를 활용하여 비교 및 분석하고자 한다. 본 연구결과 레저활동을 포함하는 규칙적인 운동활동은 노인의 근육량과 골밀도를 증진시키고, 아울러 당뇨병, 고혈압, 동맥경화, 관절염 등과 같은 성인병을 예방하며, 아울러 인지기능 증가에 따른 치매의 예방과 치료 뿐만 아니라 면역력의 증진을 통한 만성질환과 암의 예방에도 필수적인 것으로 사료된다. 특히 노인에게는 요가나 필라테스를 기반으로 하는 수행하기 쉬운 운동이 좋으며, 흥미있고 자주 할 수 있는 운동이 권장된다. 체력이 전반적으로 약하기 때문에 무리한 운동은 오히려 심혈관계의 부담, 항상성의 교란, 및 면역저하를 동반할 수 있으므로, 레저스포츠 활동, 근력운동을 포함하는 저항운동, 및 일상생활도 증가를 통한 체력증진, 충분한 휴식, 최적의 영양관리가 필요하며 추후 건강한 노인에 최적화된 스포츠 장비, 영양소 섭취와 스포츠 음료 등의 계발에 관한 연구가 이루어져야 할 것이다.
