연구배경: 흉수의 원인을 규명하는 방법으로는 임상소견, 흉수 분석, 그리고 흉막생검 등이 있다. 그러나 이와 같은 적극적인 검사에도 불구하고 약 20%의 환자에서 흉수의 원인을 모르는 것으로 알려져 있다. 결핵성 흉막염은 우리나라에서 가장 흔히 보는 흉막질환이지만 흉수에서 결핵균 양성율은 20-30%에 불과하고 흉막생검 양성율도 50%를 넘지 않아 감별진단이 어려운 경우를 임상에서 종종 경험하게 된다. 본 연구에서는 흉수의 감별진단에 있어 흉수에서의 ADA(adenosine deaminase) 및 동종효소의 활성도 측정의 유용성을 평가하고자 하였다. 방 법: 1996년 1월 부터 6월까지 단국대병원 내과에 흉수로 입원한 54명의 환자들의 흉수와 혈청에 대해 ADA 및 동종효소의 활성도를 측정하였다. 흉수의 원인으로는 결핵성 흉수가 25명, 부폐렴성 흉수가 10명, 악성 흉수가 14명, 여출성 흉수가 5명이었으며, 이들 중 소방형 흉수를 보인 경우는 결핵성 흉수가 5명, 부폐렴성 흉수가 6명이었다. 총 ADA 활성도와 동종효소 활성도 측정은 spectrophotometry로 시행하였으며, ADA2 동종효소의 활성도 측정은 ADAl의 강력한 억제제인 EHNA(erythro-9-(2-hydroxy-3-nonyl) adenine)을 이용하여 측정하였다. 결 과: 결핵성 흉수에서의 총ADA 활성도는 악성 흉수보다 높았으나 (p<0.l), 결핵성 흉수와 부폐렴성 흉수사이에는 유의한 차이가 없었다(결핵성 흉수 : $148.9{\pm}89.9IU/L$, 부폐렴성 흉수 : $129.0{\pm}119.4IU/L$, 악성흉수 : $60.7{\pm}17.8%$). 흉수에서 총 ADA에 대한 ADA2 동종효소의 활성도의 비 (ADA2%)는 결핵성 흉수에서 부폐렴성 흉수에 비해 유의하게 놓았으나(p<0.05), 결핵성 흉수와 악성 흉수 사이에는 유의한 차이가 없었다(결핵성 흉수: $57.2{\pm}10.7%$, 부폐렴성 흉수 : $35.9{\pm}17.8%$, 악성 흉수 : $60.7{\pm}17.8%$). 소방형 흉수의 경우 총 ADA 활성도는 결핵성흉수와 부폐렴성 흉수 사이에 유의한 차이가 없었으나(결핵성 흉수 : $157.8{\pm}100.8$ IU/L, 부폐렴성 흉수 : $164.3{\pm}132.3$ IU/L), ADA2% 는 결핵성 흉수에서 부폐렴성 흉수보다 유의하게 높았다(p<0.005)(결핵성 흉수 : $53.3{\pm}3.9%$, 부폐렴성 흉수 : $27.8{\pm}7.9%$). 결 론: 흉수에서 ADA동종효소의 측정은 결핵성 흉수와 부폐렴성 흉수의 감별진단에 유용하며 특히 소방형 흉수의 경우와 같이 임상적으로 강별이 용이치 않은 경우에 더욱 유용할 것으로 생각된다

Purpose : The purpose of this study was to investigate the distribution and frequency of temporomandibular joint (TMJ) effusion in magnetic resonance (MR) images of patients with disc displacements. Materials and Methods: On T2 weighted MR images of 148 TMJs taken from 74 patients presenting with TMJ pain and dysfunction, we assessed the cases showing TMJ effusion, defined as an amount of fluid that exceeded the maximum amount seen in a control group of asymptomatic volunteers. The amount of TMJ fluid was graded as: I (none or minimal), II (moderate), III (marked), and IV (extensive), according to a standard set by a reference. Disc displacement categories were also recorded. Results: Of the 148 TMJs examined in this study, 52 joints (35.1%) presented with joint effusion, 24 (16.2%) showing bilateral joint effusion. 38 joints showed upper joint space effusion, 3 showed lower joint space effusion, and 11 showed both upper and lower joint space effusion. 96 joints (64.9%) had grade I joint fluid, 27 (18.2%) grade II, 15 (10.1 %) grade III, and 10 (6.8%) grade IV. 80.0% of the joints presenting with grade IV effusion showed disc displacement without reduction. Conclusion: Joint effusion was found not only in upper, but also in lower joint spaces. The higher the effusion grade, the greater the frequency of disc displacement without reduction.

The authors assessed if there is a relationship between joint effusion and the presence of pain, and between joint effusion and disc displacement in 446 temporomandibular joints of 223 subjects who visited the Department of Oral Medicine, Kyungpook National University Hospital with the complaints of temporomandibular joint problem. The amount of joint effusion and the position of disc were determined from magnetic resonance images of the temporomandibular joints. The position of disc was classified into normal disc position, disc displacement with reduction (DDWR), and disc displacement without reduction (DDWOR). The amount of joint effusion was graded according to the extent of joint area of high signal intensity on T2-weighted MR images. These findings were correlated with one another and statistically analyzed. The results were as follows; 1. The incidence of temporomandibular joint pain Was higher in the joints with higher amount of joint effusion (P<0.001). 2. The proportion of temporomandibular joints with higher amount of effusion increased in the joints with more advanced articular disc displacement (P<0.001).

The present study has been conducted to investigate heat/mass transfer characteristics on a target plate fur arrays of circular impingement jets with and without effusion holes. A naphthalene sublimation method is employed to determine local heat/mass transfer coefficients on the target plate. The effusion holes are located at the center of four injection holes in the injection plate where the spent air is discharged through the effusion hole after impingement on the target plate. For the array jet impingement without effusion holes, the array jets are injected into the crossflow formed by upstream spent air because the impinged jets must flow to the open exit. For small gap distances, heat/mass transfer coefficients without effusion holes are very non-uniform due to crossflow effects and re-entrainments of spent air. However, uniform distributions and enhanced values of heat/mass transfer coefficients are obtained by installing the effusion holes. For large gap distances, the crossflow has little influence on heat/mass transfer characteristics on the target palate due to the large cross-sectional open area between the injection and target plates. Therefore, the distributions and levels of heat/mass transfer coefficients are almost the same for both cases.

The present study is conducted to investigate the effect of rib arrangements on an impingement/effusion cooling system with initial crossflow. To simulate the impingement/effusion cooling system, two perforated plates are placed in parallel and staggered arrangements with a gap distance of 2 times of tile hole diameter. Initial crossflow passes between the injection and effusion plates, and the square ribs (3mm) are installed on the effusion plate. Both the injection and effusion hole diameters are 10mmand Reynolds number based on the hole diameter and hole-to-hole pitch are fixed to 10,000 and 6 times of the hole diameter, respectively. To investigate the effects of rib arrangements, various rib arrangements, such as 90$^{\circ}$transverse and 45$^{\circ}$angled rib arrangements, are used. Also, the effects of flow rate ratio of crossflow to impinging jets are investigated. With the initial crossflow, locally low transfer regions are formed because the wall jets are swept away, and level of heat transfer rate get decreased with increasing flow rate of crossflow. When the ribs are installed on the effusion plate, the local distributions of heat/mass transfer coefficients around the effusion holes are changed. The local heat/mass transfer around the stagnation regions and the effusion holes are affected by the rib positions, angle of attack and rib spacing. For low blowing ratio, the ribs have adverse effects on heat/mass transfer, but for higher blowing ratios, higher and more uniform heat transfer coefficient distributions are obtained than the case without ribs because the ribs prevent the wall jets from being swept away by the crossflow and increase local turbulence of the flow near the surface. Average heat transfer coefficients with rib turbulators are approximately 10% higher than that without ribs, and the higher values are obtained with small pitch of ribs. However, the attack angle of the rib has little influence on the average heat/mass transfer.

Pleural effusion is a state, retention of a mount of liquid in pleural cavity. Main causes of pleural effusion is Congestive Heart Failure that is caused by left ventricular heart failure. And that of Congestive heart failure is caused by increase of pleural capillary pressure or remain of effusion in pleural cavity. Bilateral venous pressure of pleura make worse pleural effusion and one way of venous pressure of that bring out pleural effusion. The purpose of this study is to examine the efficacy of oriental treatment for pleural effusion is caused by heart failure. One woman of 86 years old complained the symptom of general weakness, dyspnea, flank pain, anorexia, insomnia, coughing, secretion mixed blood. The symptom is caused by effusion that is brought out acute pneumonia, heart failure. At the time of Admission, in the diagnosis of Admission, in the diagnosis of Hyuneum(懸飮) she had taken Kungha-tang hap pleurisy-bang,(芎夏湯合助膜炎方), so improved dyspnea, flank pain, insomnia, coughing. In views of examination, decrease of heart failure' s symptom and pleural effusion. After 13days of admission, she had taken palmul-tang.(八物湯). As a conseguence of that, the symptom of general weakness. anorexia is improved and she was discharged.

Simultaneous presence of ascites and pleural effusion has been documented in patients with cirrhosis of the liver, renal disease, Meigs' syndrome and in patients undergoing peritoneal dialysis. Mechanisms proposed in the formation of pleural effusion in most of the above diseases are lymphatic drainage and diaphragmatic defect. But sometimes, hepatic hydrothoraxes in the absence of clinical ascites and pleural effusion secondary to pulmonary or cardiac disease are noted. It is not always possible to differentiate between pleural effusion caused by transdiaphragmatic migration of ascites and by other causes based soly on biochemical analysis. Authors performed radionuclide scintigraphy after intraperitoneal administration of $^{99m}Tc-labeled$ colloid in 23 patients with both ascites and pleural effusion in order to discriminate causative mechanisms responsible for pleural effusion. Scintigraphy demonstrated the transdiaphragmatic flow of fluid from the peritoneum to pleural cavities in 13 patients correctly. In contrast, in 5 patients with pleural effusion secondary to pulmonary, pleural and cardiac diseases, radiotracers fail to traverse the diaphragm and localize in the pleural space. Ascites draining to mediastinal lymph nodes and blocked passage of lymphatic drainage were also clarified, additionaly. Conclusively, radionuclide peritoneal scintigraphy is an accurate, rapid and easy diagnostic tool in patients with both ascites and pleural effusion. It enables the causes of pleural effusion to be elucidated, as well as providing valuable information required when determining the appropriate therapy.
