Background: Diagnosis of subpulmonary effusion is thought to be somewhat difficult more than pulmonary effusion. Clinical course and pathophysiology are thought to be different from typical pulmonary effusion. This study was done for increasing high suspicious index and early diagnosis of subpulmonary effusion. Method: Among the patients at dept. of chest medicine, National Medical Center from January 1990 to Dec. 1993, 232 cases of typical pulmonary effusion and 42 cases of subpulmonary effusion were studied. Result: 1) The ratio of subpulmonary effusion and typical pulmonary effusion was about 1:5. 2) Male to Female ratio was 1:1 in both effusion. 3) Rt. side pleural and subpleural effusion were slightly predominant. 4) Subjective symptoms are chest pain, cough and exertional dyspnea. There is no difference between subpulmonary and typical pulmonary effusion. 5) Duration of symptom was slightly longer in subpulmonary effusion. 6) The most common cases of pleural effusion is tuberculosis in both subpulmonary & typical pulmonary effusion. Non-specific pleuritis was more common in subpulmonary effusion. 7) Pleural effusion was recurred about one fifth in both subpulmonary & pulmonary effusion. Conclusion: We studied clinical course and laboratory findings between subpulmonary & pulmonary effusion. However there are no definite difference between subpulmonary & pulmonary effusion. Duration of symptom was slightly longer in subpulmonary effusion. Most common cause was tuberculosis. Non specific pleuritis was more prevalent in subpulmonary effusion.

Background: Etiologic diagnosis of pleural effusion is usually made by clinical characteristics, pleural fluid analysis and pleural biopsy. But, despite careful diagnostic study, the cause of pleural effusion cannot be found in about 20 percent of patients, especially in loculated pleural effusions. Tuberculous pleurisy is one of the most common cause of pleural effusion in Korea. But, pleural fluid culture for Mycobacterium tuberculosis are positive in only 20 to 30 percent of patients and typical pleural biopsy finding in less than 50 percent of patients with this disease. In recent studies, adenosine deaminse(ADA) and its isoenzymes were proposed to be a useful diagnostic tool for differential diagnosis of pleural effusion. We investigated the pattern of ADA and its iscenzyme activities in various cause of pleural effusions to evaluate the diagnostic value of measuring ADA and its isoenzymes. Method: We measured total ADA and its isoenzyme activities in pleural fluid and serum from 54 patients with pleural effusion(25 tuberculous pleural effusion, 10 parapneumonic effusion, 14 malignant pleural effusion, 5 transudative pleural effusion), including 5 loculated tuberculous pleural effusions and 6 loculated parapneumonic effusions. Total ADA activity was measured by the spectrophotometric method and ADA2 isoenzyme activity was measured with same method using EHNA, potent inhibitor of ADA1 isoenzyme activity. Result: Total ADA activity of tuberculous pleural effusion was higher than malignant pleural effusion(p<0.01), but no significant difference was found between tuberculous pleural effusion and parapneumonic effusion(tuberculous pleural effusion: $148.9{\pm}89.9IU/L$, parapneumonic effusion: $129.0{\pm}119.4IU/L$, malignant pleural effusion: $48.7 {\pm}39.7IU/L$). Percentage of ADA2 activity to total ADA activity(ADA2%) of pleural effusion of tuberculous pleurisy was higher than parapneumonic effusion(p<0.05). but no significant difference was found between tuberculous pleural effusion and malignant pleural effusion(tuberculous pleural effusion: $57.2{\pm}10.7%$, parapneumonic effusion: $35.9{\pm}17.8%$, malignant pleural effusion: $60.7{\pm}4.1%$). In loculated pleural effusion, ADA2% of tuberculous pleural effusion was higher than parapneumonic effusion(tuberculous pleural effusion: $53.3{\pm}3.9%$, parapneumonic effusion: $27.8{\pm}7.9%$). Conclusion: Measurement of ADA isoenzyme activity is useful for differentiating tuberculous pleural effusion from parapneumonic effusion, especially in loculated pleural effusion.
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.
Objectives: We report one patient with pleural effusion and effusion-related symptoms in small cell lung cancer (SCLC) successfully treated with Gunreyngtang-gagambang. Methods: Gunreyngtang-gagambang was administered at 30 minutes after mealtime, three times a day, for two months. Except for herbal medicine, the patient did not take any treatment including pharmaceutical or non pharmaceutical for effusion. Result: Two months later, the symptoms and the pleural effusion had disappeared from chest X-ray. Conclusion: Gunreyngtang-gagambang was effective for treatment of malignant pleural effusion due to small cell lung cancer.
Background : Cytokines are chemical mediators that control and modulate many inflammatory processes. They work in different fashions in a variety of diseases. Discriminating between malignant effusion, tuberculous effusion, and parapneumonic effusion are crucial from the clinical view-point in Korea. In the current study, interferon-gamma (IFN-${\gamma}$), soluble interleukin-2 receptor (IL-2R), interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured for this purpose. Methods : Pleural fluids from patients with malignant disease, tuberculosis, parapneumonic effusion and lung empysema were collected and gauged using commercial ELISA kits. Results : 34 patients were enrolled in this study. Among these 15 cases were malignant effusions, 12 were tuberculosis pleurisy and 7 were parapneumonic effusion and lung empyema. The levels of cytokines measured in this study were as follows, in order of frequency, malignant effusion, tuberculous effusion, parapneumonic effusion and lung empyema. The levels of INF-${\gamma}$ were higher in tuberculous effusion than in malignant or parapneumonic effusion ($295.5{\pm}585.5$ vs. $16.7{\pm}50$ vs. $10.0{\pm}0$ pg/ml, p>0.05). The levels of IL-2R were higher in tuberculous effusion than in malignant or parapneumoruc effusion ($7423.5{\pm}3752.8$ vs. $3247.4{\pm}1713.3$ vs. $3790.2{\pm}3201.1$ pg/ml, p<0.05). No significant differences were found in the levels of IL-6 between the groups ($600{\pm}12.8$ pg/ml in malignant effusion, $556.4{\pm}161.7$ pg/ml in tuberculous effusion, $514.4{\pm}224.8$ pg/ml in parapneumoruc effusion). IL-10 levels were higher in parapneumoruc effusion than in malignant or tuberculous effusions ($98.4{\pm}141.7$ vs. $28.2{\pm}55.5$ vs. $11.3{\pm}11.7$ pg/ml, p<0.05). Conclusion : These results suggest that the measurement of IL-2R levels in pleural fluids may be a useful means of differentiating between tuberculous effusion and pleural effusions of other origins, and that the measurement of IL-10 levels in pleural fluids may be useful to differentiate between parapneumonic effusion and pleural effusions of other origins.
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.
