Purpose : The purpose of this study was to investigate characteristics of the forced pulmonary function test effect by changes in lung function related to postures and by Transverse Abdominis(TrA). Contraction in standing position during forced inspiration and expiration with young female adults. Methods : 10 young female adults were recruited this study. pulmonary Function test was measured with a Master-screen Body (VIASYS Inc., CA, 미국). To check the changes in lung function with different postures, we tested pulmonary function in the standing and supine position each. In the standing position, while the transversus abdominis was activating, we compared the forced inspiration with the forced expiration. Statistical analysis was used Independent t-test to know difference between forced inspiration and expiration of activated TrA. Results : According to the study, the change of pulmonary function were statistically significant difference in the standing compared to the supine position. The contraction of the transversus abdominis causes decrease in the change of forced inspiration and increase in the change of forced expiration. Conclusion : These results indicate that spontaneous contraction of the TrA in standing position helps pulmonary function. And the selective contraction of the transversus abdominis at the end of forced inspiration makes increases in the forced expiration.

Atelectasis may be defined as collapse of the lung due to absence of air within the alveoli. It may involve anatomic segments, lobes, or whole lungs but also may be a diffuse miliary process, as in the adult respiratory distress syndrome. The key to treatment are the anticipation and prevention of atelectasis in various clinical situations, the recognition and treatment of underlying disease, and the prompt initiation of vigorous treatment once atelectasis is found. Repeated assessment by physical examination is necessary to determine the presence of atelectasis and its response to treatment. During the period of January, 1981 to October, 1990, 100 patients with atelectasis were treated in the department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital. There were 70 males and 30 females ranging from 3 days to 79 years of age. The occurrence ratio of right to left side was 2.1 : 1. The underlying pathologic lesions of atelectasis were pneumonia with effusion(28), lung ca.(24), pulmonary tuberculosis(24), and chronic empyema(9), The treatment procedure for atelectasis were closed thoracostomy in 26 cases, ressection in 21 cases, therapeutic bronchoscopy in 14 cases and etc.

Post-pneumonectomy empyema thoracis is an uncommon, but very serious problem. Early diagnosis & adequate drainage followed by thoracoplasty and or myoplasty are very important principles for the management of the empyema thoracis & will enable patient to recover from the toxic effects. During the period of January, 1985 to December, 1990, 13 patients with post-pneumonectomy empyema thoracis were treated in the department of Thoracic and Cardiovascular Surgery, Yonsei University College of Medicine. There were 10 males % 3 females ranging from 31 years to 79 years of age. The occurrence ratio of left to right side was 8: 5. The underlying pathologic lesions of empyema thoracis were pulmonary tuberculosis[7], lung ca. [2] pneumothorax[2], lung abscess[1] pneumonia[1]. We treatment procedure for post-pneumonectomy empyema thoracis were open window thoracostomy in 10 cases, Clagett procedures in 2 cases, one thoracoplasty, and two cases of Clagett procedures followed by open window thoracostomy in one cases.

일측폐장을 절제한 뒤 대상성증식기의 폐장을 태아폐장증식의 모델로 삼고 이때 steroid가 대상성증식중의 폐장내 제II형폐포세포의 폐포표면활성물질의 분비에 미치는 영향을 알아보기 위한 본 실험의 결과를 요약하면 다음과 같다. 1. 잔류폐장의 무게 및 체중에 대한 폐장무게의 비는 폐절제후 betamethasone을 투여한 군에서 폐절제군에 비해 감소하는 경향을 보였다. 2. 폐세척액내의 인지질인의 함량은 폐절제후 betamethasone을 투여한 군에 있어서는 무처치대조군에 비해서는 유의한(p<0.01) 증가를 보였고 폐절제군에 비해서는 증가하는 경향을 보였다. 3. TLC(thin layer chromatography)를 통해 폐세척액내의 인지질의 조성을 조사한 결과, 폐절제후 betamethasone을 투여한 군은 무처치대조군 및 폐절제군과는 다른 양상을 보였다. 이상의 실험결과로 미루어 steroid는 태아폐장의 대상성증식기에 폐포표면활성물질의 분비를 증가시키며 동시에 제II형폐포세포에서 분비되는 폐포표면활성물질의 주성분인 인지질의 조성에도 변화를 일으켜 폐장의 융압률을 증가시킨다고 사료된다.

CA19-9의 상승은 췌장 및 담도계 악성 종양을 시사하는 소견이다. 하지만, 최근에 양성 소화기계 질환 뿐 아니라 특발성 간질성 폐렴, 교원성 폐 질환, 미만성 범세기관지염, 기관지확장증 등 다양한 양성 폐 질환에서도 혈중 CA19-9 수치가 증가되어 있다고 보고된다. 저자들은 최근 지속적으로 혈중 CA19-9 수치는 증가되어 있지만, 내시경적 역류성 담도 췌장 조영술, 복부 전산화 단층 촬영, PET-CT에서 악성 종양이 발견되지 않은 기관지확장증 1예를 경험 하였다. 3년 10개월의 추적 관찰 기간 중에도 췌장암과 같은 악성 종양은 발견되지 않아서, 혈중 CA19-9 수치의 상승은 기관지확장증에 의한 것으로 추정 되었다. 혈중 CA19-9 수치의 상승은 환자의 임상 양상과 연관하여 조심스럽게 판단하여야 될 것으로 생각된다.

The experimental study for extracorporeal preservation of the heart-lung preparation by autoperfusion system was performed in 10 dogs. Under intravenous Pentothal endotracheal anesthesia bilateral thoracotomies were performed. A 24F cannula connected to a plastic reservoir bag located 100 cm above the level of the heart was introduced into the aortic arch. Left subclavian, innominate artery, and descending aorta were ligated and divided. Both vena cavae were ligated and divided after the bag was half filled with blood. A 24F catheter inserted into right atrium and connected to the plastic bag in order to keep constant the preload. The thoracic trachea was intubated and the lungs were ventilated. The heart-lung preparations were removed en bloc and floated in a $34^{\circ}C$ bath of Hartmann solution. The preparations were observed for from 2 hours to 8 hours, with the average of 5.2 hours. Hemodynamic and hematologic variables were measured during preharvest and autoperfusion. The pH revealed severe respiratory alkalosis due to very low $PaCO_2$ during autoperfusion ; $PaO_2$ remained constant for 130-140 mmHg; $A-aDO_2$ increased markedly. The static inspiratory pressure [SIP] at late autoperfusion [6hr] increased significantly as compared with at early autoperfusion [2hr]. There was no difference between white blood cell counts from right atrium and those of left atrium. Heart rates remained constant for 110-120/min; cardiac outputs maintained to approximately 0.6L/min; mean aortic pressures, 75 mmHg; mean pulmonary arterial pressures, 15-18 mmHg; mean right atrial pressures, 9-13 mmHg; mean left atrial pressures, 12 mmHg lower than those of right atrium. Serum Na maintained with normal range during autoperfusion; K increased significantly; Ca decreased progressively. Hemoglobin and hematocrit decreased significantly during autoperfusion. The study demonstrated that stable hemodynamics could be maintained throughout the experiment and the preparation of the lung seemed to be inadequate, especially after 3-4 hours, such as high $A-aDO_2$, increased SIP, and scattered atelectasis and edema in their gross appearances.

배경: 최근 항암화학요법의 발달에도 불구하고 전이성폐암에 대한 예후는 불량하다. 이에비해 전이성폐암에 대한 외과적 요법후 좋은 결과를 보이는 보고가 증가하고 있다. 그래서 전이성 폐암에 대한 치료에 도움이 되고자 본원의 경우를 관찰하였다. 대상 및 방법: 1983년부터 1997년까지 수술적 치료를 했던 17례를 분석하였고 Kaplan-Meier 방법으로 5년생존률을 구하였다. 결과: 평균연령은 42.8세였고 남녀비는 10:7이었다. 수술은 단일폐엽절제술이 8례, 전폐적출술이 3례, 부분절제술이 1례, 쌍폐엽절제술이 1례, 폐엽절제술 및 부분절제가 3례있었다. 술후 5명이 사망하였고 이중 재발로 인한 것은 3례였다. 나머지 12례의 환자들중 3명은 재발하여 현재 외래추적관찰중이며 9명은 재발없이 건강한 상태로 외래추적 관찰중에 있다. 술후 평균 생존기간은 40.5개월이었다. Kaplan-Meier 방법으로 구한 5년생존율은 60.4%였다. 결론: 앞으로 더많은 경험이 필요하지만 전이성폐암에 대해서 더 적극적인 수술적치료를 하는 것이 필요하다고 생각한다.

This study was conducted to examine the chemical composition of kiwifruit skin, and to est its anti-microbial activities and cytotoxicities, thus, exploring ways for the economic utilization of kiwifruit skin. Four varieties of kiwifruit were examined: Daeheung, Bidan, Haegeum No.1 and Hayward. Vitamin C content in the fruit skins of Bidan, Daeheung, Haegeum No.1 and Hayward were 72.44, 67.22, 62.51 and 61.44mg/100g, respectively. Total amino acids content in the fruit skins of Bidan, Haegeum No.1, Hayward and Daeheung ere 808.31, 706.02, 629.07 and 464.83mg/100g dry weight, respectively. K and Ca content ere $17.20-45.70{\mu}g/mL$ and $4.58-10.15{\mu}g/mL$. While, other inorganic matter contents were below $4.89{\mu}g/mL$. Anti-microbial activity of kiwifruit skin extracts, in terms of the diameter of inhibition zone when tested against five gram positive and three gram negative microbial trains (even in the concentration of 2,000mg/L), was less than 14.1mm. The hyperplasia inhibition of lung cancer cells by methanol extracts from Bidan and Haegeum No.1 using concentrations of 800mg/L were 27.7% and 14.5%, however, those from Daeheung and Hayward were below 3% Consequently, it will be useful to know that kiwifruit skin can be added to processed goods which demand for higher concentrations of vitamin C, amino acids, K and Ca.

High Electromagnetic Field (EMF) with an intensity of 1 mT (Tesla) inhibited the growth of both human normal lung and immune T cell down to $20-30\%$, compared to that of an unexposed case. The human T-cells, Jurkat, were more severely affected by EMF than the human lung cells, which showed a relatively slow cell growth and substantial releas of $Ca^+2$ (3.5 times higher than the human T-cells). However, the growth of hepatoma carcinoma, Hep3B, was enhanced by twice that of an unexposed case. The EMF intensity and exposure time did not affect the growth of the cancer cells very much, while it significantly affected the growth of normal cells. Accordingly, it is possible that EMFs may play a role in the initiation of cancer. The EMFs disturbed the signal transduction and membrane systems, such that a five times higher amount of PKC-${\alpha}$ was released from the cell membrane than in the control. Extended exposure to EMFs, for more than 48 hours, also led to 1 $90\%$ necrotic death pattern from apoptotic cell death. Finally, EMF at an intensity of 1mT with a 24-T exposure promoted the differentiation of HL-60 cells to monocytes/macrophages, possibly causing potential acute leukemia.
