Abstract
The level of interferon-gamma (IFN-gamma) in pleural fluid has been reported to be increased in pleural tuberculosis. Nevertheless, its diagnostic value has not yet been well-established, and immunocompromised patients have not previously been evaluated. The aim of this study was to determine the value of the IFN-gamma level in pleural fluid for diagnosing tuberculous pleurisy in immunocompetent and immunocompromised patients. Three hundred and eighty eight consecutive patients were studied prospectively (73 with tuberculous pleural effusions, including nine with concurrent human immunodeficiency virus (HIV) infection and one after liver transplantation, and 315 with nontuberculous effusions). IFN-gamma was measured by radioimmunoassay. The sensitivity of the test, using a 3.7 U.mL-1 cut-off point, was 0.99 (95% confidence interval (95% CI) 0.93-1.00) and the specificity was 0.98 (95% CI 0.96-1.00). The sensitivity of the test did not differ in HIV-positive and HIV-negative patients. Patients with lymphoma, vasculitis or vascular connective tissue disease did not have abnormal IFN-gamma values. In conclusion, the level of interferon-gamma in pleural fluid is a very good diagnostic marker of tuberculous pleural effusion, even in immunocompromised patients.

Abstract
Combining cytomorphology and immunophenotypic data in evaluation of effusions for lymphomatous involvement is reliable, non-invasive, and expeditious. In this study, 30 effusion specimens from 30 patients with clinically suspected or previously diagnosed non-Hodgkin's lymphoma (NHL) were evaluated cytomorphologically and by flow cytometric immunophenotyping with a large panel of monoclonal antibodies. Of 11 patients with a previous diagnosis of NHL, 50% had cytomorphologic and immunophenotypic evidence of lymphomatous involvement of effusion specimens; therefore, flow cytometric immunophenotyping is recommended in these cases since there may be substantial therapeutic impact. In addition, 69% of the effusions positive for lymphomatous involvement represented newly diagnosed NHL; in 36% of these cases, tissue biopsy was not necessary since they were either high-grade (lymphoblastic or small, non-cleaved cell type) or of the small lymphocytic lymphoma cell type.

Abstract
OBJECTIVE To evaluate the efficacy of Ber-EP4 in distinguishing epithelial cells from mesothelial cells in routine cytologic preparations. STUDY DESIGN Paraffin-embedded cell blocks of serous effusions from 32 patients (11 metastatic adenocarcinomas, 16 reactive mesothelial proliferations and 5 malignant mesotheliomas) were immunostained with Ber-EP4. For comparison, cell block preparations of adenocarcinomas and mesotheliomas were also immunostained with the most commonly applied markers of adenocarcinoma: carcinoembryonic antigen (CEA), B72.3 and Leu-M1. In addition, cytocentrifuge preparations of 14 reactive effusions and 2 metastatic adenocarcinomas were stained prospectively with Ber-EP4. RESULTS All adenocarcinomas showed intense membrane staining, while all mesothelial proliferations, both benign and malignant, were negative. The Ber-EP4-positive immunostaining was remarkably clean, with very minimal nonspecific staining. CEA stained 11/11 adenocarcinomas, B72.3 stained 10/11, and Leu-M1 stained 8/11; mesotheliomas were negative with all three antibodies. CONCLUSION Ber-EP4 is at least as useful as CEA, B72.3 and Leu-M1 in the diagnosis of serous effusions. It has the advantage of high sensitivity and ease of interpretation because of the high percentage of tumor cells stained, characteristic membranous staining and lack of cross-reaction with background inflammatory cells.

Abstract
OBJECTIVE Natural killer (NK) cells are cells of undefined lineage that are capable of lysing certain tumor cell lines in vitro. Determination of NK cell percent (NK%) in effusions by flow cytometry could aid in the detection of malignancies. STUDY DESIGN Over a six-month period at the Houston Veterans Affairs Medical Center, fresh effusions were routinely processed for cytology, and a portion was submitted for lymphocyte immunophenotyping using the FACScan and a panel including CD16/CD56 for NK cells. Seventy fluids (42 pleural, 28 peritoneal) from 62 men were examined. RESULTS NK cell percents were markedly increased in 15 cases (29-68%, mean 45.5) and low in 55 (2-20%, mean 8). Fourteen of the 15 cases with increased NK% were positive for carcinoma (93%), while 54/55 cases with low ones were negative for carcinoma (98%). Mesotheliomas, lymphomas and leukemias had low NK%. CONCLUSION Using the Mann-Whitney U test, an increase in NK% predicts metastatic carcinoma with a P level of < .00001.

Abstract
Expression of CD44 isoform that contains variant exons (v1-v10) has been implicated in tumor progression and metastasis. Especially, CD44 isoform containing v6 (CD44v6) and that containing v7 (CD44v7) were shown to confer full metastatic behavior on tumor cells. We examined the expression of CD44v6 and CD44v7 in malignant pleural effusions (13 lung cancers and 4 non-lung cancers) and in benign pleural effusions (7 tuberculosis and 3 pneumonia) with Southern blot analysis of reverse transcription (RT)-polymerase chain reaction (PCR) products. CD44v6 was expressed not only in malignant pleural effusions (12 of 13 lung cancers and 4 of 4 non-lung cancers), but also in benign pleural effusions(9/10). In contrast, although expression of CD44v7 was found in most malignant pleural effusions (12 of 13 lung cancers and 4 of 4 non-lung cancers), it was found in only a few cases of benign pleural effusions. These results suggest that the expression of CD44v7 may be correlated with a tumor-specific event such as metastasis or dissemination in malignant pleural effusion, while no such correlation can be found with CD44v6.

Abstract
STUDY OBJECTIVE Human immunity has been found to have two major components, cellular and humoral immunity. T-helper type 1 (Th1) pathway favors cellular immunity and Th2 pathway favors humoral immunity. Early determination toward Th1 and Th2 cells in the immune response is dependent on the balance between interleukin-12 (IL-12), which favors Th1 responses, and IL-4, which favors Th2 responses. IL-2 and interferon-gamma (IFN-gamma) are produced in the Th1 pathway, and IL-4 and IL-10 are produced in the Th2 pathway. Lack of cellular immunity, IL-2, and IFN-gamma had been reported in malignant pleural effusions. However, to our knowledge, there are no previous reports on other cytokine components involving Th1 or Th2 pathway. The present study was designed to answer these questions. DESIGN Cytokine levels in peripheral blood and pleural fluid of 21 patients with malignant pleural effusion, including IL-4, IL-10, and IL-12, were analyzed with enzyme-linked immunosorbent assays. Lymphocyte subpopulations of peripheral blood and pleural effusion were also studied by using flow cytometry. MEASUREMENTS AND RESULTS The results showed a significant increase in IL-10 level as compared with blood samples. IL-4 and IL-12 were below minimal detectable concentrations both in the blood and the effusion. The ratio of pleural helper T cells was significantly higher than in the blood (p = 0.0002). The ratio of pleural natural killer (NK) cells was significantly lower than in the blood (p = 0.0001). The ratio of pleural suppressor T cells was lower than blood with borderline significance (p = 0.0522). No significant change in B-lymphocyte ratio between blood and pleural effusion was found (p = 0.2471). There was no correlation between difference in IL-10 level and lymphocyte subpopulation of pleural effusion and blood samples. CONCLUSIONS Helper T-cell subpopulations were increased while NK and suppressor T-cell subpopulations were decreased in malignant pleural effusions. The decrease in NK cell subpopulations with elevated IL-10 and minimal IL-12 concentration in neoplastic pleural effusion would suggest the usage of IL-12 or antibody of IL-10 to improve local cellular immunity. Further study is needed.

Abstract
Generation of soluble cytokine receptors is a general phenomenon, and the roles of several such receptors have been investigated in clinical settings. Unlike other soluble cytokine receptors, soluble interleukin-6 receptor (sIL-6R) can act as an agonist and thus is implicated as an important modulator in the acute-phase reaction of prolonged inflammation. The purpose of the present study was to determine the roles of pleural sIL-6R in both differential diagnosis of pleural diseases and in the induction of acute-phase protein. Specific sandwich enzyme-linked immunosorbent assays were used to determine sIL-6R and IL-6 in 19 tuberculous, 48 malignant and 10 transudative effusions. Although IL-6 levels in pleural effusions were strikingly different, no significant differences in pleural sIL-6R levels were found between the groups. Pleural levels of IL-6 were invariably much higher, whereas those of SIL-6R were invariably lower than serum levels. Furthermore, IL-6, but not sIL-6R, levels in effusions correlated significantly with serum C-reactive protein levels. These results suggest that: (1) pleural levels of sIL-6R are not increased even in strong inflammation such as tuberculous pleurisy, nor significantly different among pleural diseases; and (2) the local levels of sIL-6R are not as important as expected for the induction of acute-phase proteins in patients with pleural diseases.

Abstract
Interleukin (IL)-1 is a key cytokine in inflammatory reactions. To clarify the mechanism of inflammation in the pleural cavity, we investigated the contribution of IL-1 and its antagonism to inflammatory processes in the pleural cavity. Interleukin-1 receptor antagonist (IL-1Ra) levels as well as IL-1 beta and interferon-gamma (IFN-gamma) levels were measured by enzyme immunoassay in pleural effusions from 70 patients. Pleural macrophages were also examined as possible sources of these cytokines in 10 patients. IL-1Ra was detectable in 28 patients (40%) out of 70 patients with pleural effusions. Patients with tuberculosis had significantly higher IL-1Ra as well as IFN-gamma levels in pleural effusion than patients with lung cancer. Transudative pleural effusions had low or undetectable IL-IRa levels. On the other hand, IL-1 beta levels were low, except in cases of parapneumonic pleural effusion. Spontaneous production of IL-1Ra pleural macrophages was observed in six patients, and IL-4 significantly augmented its production. Although spontaneous production of IL-1 beta was observed in only two patients, pleural macrophages produced significant amounts of IL-1 beta in response to lipopolysaccharide in all 10 patients examined. These results suggest that interleukin-1 receptor antagonist regulates various reactions by interleukin-1 in pleural effusion, and that pleural macrophages may act in situ as a source of interleukin-1 receptor antagonist.

Abstract
Interleukin-8 (IL-8) is a recently described potent chemotactic factor that may be involved in the pathogenesis of pleural effusions. To understand the actual mechanisms mediating the inflammatory response, changes in cellular components and IL-8 level in pleural fluid of different aetiologies were evaluated. Thirty-four patients (19 male, 15 female) with a mean age of 46 +/- 22 years (range 16-92) were included in the study. Of these, 13 had tuberculous pleural effusion, seven had empyema/parapneumonic pleural effusion, and 14 had malignant pleural effusion (seven adenocarcinoma, three ovarian carcinoma, two lymphoma, one chronic myeloid leukaemia, and one small cell carcinoma) with positive cytology. Differential cell counts in the pleural fluid were obtained using cytocentrifuge preparations. The concentrations of IL-8 in pleural fluid were measured by the ELISA method. Interleukin-8 was detected in all 34 pleural fluid samples. The serum IL-8 level was analysed only in the empyema/parapneumonic pleural effusion group. The mean IL-8 levels of tuberculous, empyema/parapneumonic, and malignant pleural effusions were 1420 +/- 1049 pg ml-1, 4737 +/- 2297 pg ml-1, and 1574 +/- 1079 pg ml-1, respectively. The IL-8 levels in the empyema/parapneumonic group were significantly raised over malignant and tuberculous groups (P < 0.02). The mean pleural fluid neutrophil counts in tuberculous, empyema/parapneumonic and malignant pleural effusions were 315 +/- 575 cells mm-3, 11,136 +/- 12,452 cells mm-3, and 635 +/- 847 cells mm-3, respectively (P < 0.003). There was a significant positive correlation between pleural IL-8 levels and neutrophil counts (r = 0.46, P < 0.006). The levels of IL-8 in paired samples of serum and pleural fluid in the empyema/parapneumonic effusion group were compared, and the concentration of IL-8 was higher in the pleural effusion than serum (means, 4737 +/- 2297 pg ml-1 and 130.0 +/- 62.5 pg ml-1, respectively, P < 0.03). There was a significant negative correlation between IL-8 concentrations in serum and pleural fluid (r = -0.80, P < 0.03). This data suggests that production of IL-8 in pleural effusion may play a key role in initiation and maintenance of inflammatory reactions, especially in empyema/parapneumonic pleural effusions. It may offer the basis for introduction of novel anti-inflammatory agents in treatment.

Abstract
Pleural effusion in chronic lymphocytic leukemia (CLL) is a relatively rare phenomenon. We report a case of a pleural effusion associated with B-cell CLL but with predominantly reactive T lymphocytes in the effusion. A cell surface phenotype study showed that T lymphocytes predominated in the pleural effusion, although B lymphocytes were predominant in the peripheral blood. Genotypic analysis of the cells in the peripheral blood, bone marrow, lymph node, and pleural effusion showed the same rearrangement pattern of the immunoglobulin heavy chain genes consistent with a B-lymphocytic neoplasm (CLL). A pleural biopsy demonstrated diffuse infiltration of lymphoid cells. Most of the cells demonstrated T cell markers, although some cells revealed B cell markers by immunologic staining. These results suggested that the pleural involvement by B-CLL may have caused a reactive T-lymphocyte proliferation in the pleura and pleural effusion. To our knowledge, this is the first published case indicating that genotypic analysis of immunoglobulin heavy chain gene rearrangement may be useful in the diagnosis of a pleural effusion associated with B-cell CLL.

Abstract
Thoracentesis is a procedure often performed in children with pleural effusions to assist in diagnosis and management. Its safety and utility for immunocompromised patients with neutropenia (absolute neutrophil count, <1,500 polymorphonuclear leukocytes and band forms per microL) is unclear. We reviewed our experience over a 10-year period to evaluate the role of thoracentesis for neutropenic children with cancer who had pulmonary effusions of presumed infectious etiology. Twenty-two patients were identified, and 18 had absolute neutrophil counts of < or = 500/microL. Empirical antibiotics had been administered to 95% of these patients and antifungal agents to 72%. Two patients' cultures were positive for fungal organisms: Aspergillus terreus in one case and Candida albicans in the other. Both of these patients had been receiving antifungal therapy. Therapy was altered for these two patients plus one additional patient in whose pleural fluid tumor cells were unexpectedly found. Eight of the remaining 19 patients underwent another diagnostic procedure, yielding five additional diagnoses. In conclusion, thoracentesis is safe and should be considered as a diagnostic test for febrile neutropenic patients with pulmonary effusions of presumed infectious etiology, although more invasive tests may be warranted.

Abstract
Twenty-one patients with malignant peritoneal or pleural effusions of gastric carcinomas were treated with intracavitary injection of lentinan (LNT). LNT was injected at a dosage of 4 mg/week for 4 weeks. In total, fifteen (71%) of twenty-one patients demonstrated clinical responses. Toxicity caused a high fever in only one case. LAK and ATK activities induced from peritoneal exudate cells (PEC) after culture with autologous tumor and interleukin-2 were examined before and after LNT injection. ATK activity was augmented, but LAK activity was reduced after LNT injection. These results indicate that intracavitary injection of LNT is a useful treatment for malignant effusions, and that LNT augments the induction of cytotoxic T-lymphocytes.

Abstract
We analyzed the T cell receptor (TCR) V beta repertoire of lymphocytes obtained from patients with malignant effusion treated by locoregional immunotherapy. Polymerase chain reaction using a panel of V beta subfamily specific oligonucleotide primers(V beta 1-20) was employed after reverse transcription of mRNA isolated from the locoregional cells. No major oligoclonality of TCR repertoire was observed in effusion lymphocytes before the treatment. The expression level of V beta 13.1 repertoire was significantly higher in effusion lymphocytes than in peripheral blood lymphocytes before treatment. V beta 20 gene expression increased significantly after locoregional administration of OK-432. It is suggested that TCR V beta 13.1 may be responsible for effusion lymphocytes and TCR V beta 20 for OK-432-related antigenic stimulus.

Abstract
This work was designed to study the proliferative response of tumor-associated lymphocytes (TAL) from neoplastic effusions against autologous tumor cells and the immunophenotype pattern of TAL from neoplastic effusions and that of PBMC of the same patients. We also compared the serum levels of the cytokines interleukin (IL) 1 beta, 2 and 6, tumor necrosis factor-alpha (TNF alpha) and soluble IL-2 receptor (sIL-2R) with those present in neoplastic effusions of the same patients. Moreover, we examined the ability of TAL and peripheral blood mononuclear cells (PBMC) to produce and release the cytokines and sIL-2R and to express membrane CD25 following their stimulation with phytohemagglutinin (PHA) in vitro. Finally, we compared the cytokines/sIL-2R production and membrane CD25 expression by PHA-stimulated PBMC of the patients with neoplastic effusions with a series of 90 cancer patients without neoplastic effusions and 20 normal healthy subjects. Thirteen neoplastic pleural and eight peritoneal effusions were collected from 11 patients with primary lung cancer, 7 with primary epithelial ovarian cancer, 1 with breast cancer, 1 with pleural mesothelioma, and 1 with pancreatic cancer. The proliferative response of TAL from neoplastic effusions against autologous tumor cells was lower than the response to PHA, IL-2, and anti-CD3, but significant. The percentage distribution of CD3+ and CD8+ lymphocyte subpopulations was higher in peritoneal than in pleural effusions, while the CD16+ subset was higher in pleural than in peritoneal effusions. The percentage distribution of CD16+ was significantly lower in pleural effusions than in PBMC of patients with pleural effusions.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Differentiation of reactive and/or atypical mesothelial cells from malignant epithelial cells in serous effusions remains a frequent diagnostic problem. Since epithelial membrane antigen (EMA) positive malignant cells in serous effusions have been reported in almost all adenocarcinomas and most malignant mesotheliomas, immunoreactivity for EMA is felt to be less useful than other antibodies in the workup of problematic serous effusions. However, immunostaining of reactive and/or atypical benign mesothelial cells for EMA has not been well studied, with only a few series reporting either weak or negative staining for EMA. This study was undertaken to evaluate how often reactive and/or atypical appearing mesothelial cells stain positively for EMA. One hundred eighty serous effusions (115 pleural, 55 peritoneal, and 10 pericardial) from 123 females and 57 males ages 20 to 89 yr were evaluated in which an antibody panel including EMA was performed on cell blocks (141 cases), cytospins (36 cases), or both (3 cases). Of the 100 cytologically positive cases, EMA immunoreactivity was present in 97/100 (97%) cases. One EMA negative case suspicious for a metastatic renal cell carcinoma was lost to follow-up and not included in the analysis. The remaining three negative cases consisted of malignancies not expected to have EMA positive cells (small cell carcinoma, neuroblastoma, and synovial sarcoma). Therefore, EMA was positive in virtually 100% of the remaining malignant cases. In the 78 cytologically negative cases, EMA positivity was present in 3/78 (3.8%) cases. Clinical follow-up of up to 14 mo in these three cases revealed no evidence of malignancy.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The diagnostic value of the novel tumor marker CYFRA 21-1 in malignant pleural fluid was assessed in comparison to carcinoembryonic antigen (CEA). CYFRA 21-1 and CEA were measured in pleural fluid obtained from patients with 108 malignant and benign diseases. The levels of pleural fluid CYFRA 21-1 in malignant diseases (median: 84.5 ng/ml) were statistically higher than those in benign diseases (median: 13.9 ng/ml; p < 0.01). The CYFRA 21-1 test was able to discriminate significantly between squamous cell lung cancer and pneumonia (p < 0.01), while pleural fluid CEA levels could not. Receiver operating characteristic (ROC) curve analysis showed that the CYFRA 21-1 test has an advantage over CEA because of its higher specificity. These results indicate that measurement of CYFRA 21-1 in pleural fluid is a new tool, in addition to cytologic examination, to discriminate between malignant and benign diseases.

Abstract
AIMS To determine whether the monoclonal antibody (MoAb) 83D4, previously shown to be highly specific for carcinoma cells, can be used as an immunocytological marker to discriminate between benign and malignant cells in serous effusions; and to test for a correlation between expression of the antigen reacting with MoAb 83D4 on effusion cells and the amount of soluble 83D4 antigen in effusion fluids. METHODS Thirty three pleural and 23 peritoneal effusions from 56 cancer patients with metastatic disease were tested for the presence of Tn associated 83D4 antigen by immunocytochemical staining, and for the presence of soluble antigen in supernatants. The patients had undergone various chemotherapy and radiation therapy protocols. RESULTS As a result of the various types of treatment, the cytological characteristics of the cells were often modified and the antigenic epitopes may have been altered. Positive staining for 83D4 MoAb was obtained in 36 (97%) of the 37 malignant effusions, eight (73%) of 11 suspect effusions, and three (38%) of the eight apparently benign effusions (free of malignant cells). In these latter cases, cytological reassessment showed a few suspect cells in two cases. 83D4 soluble antigen was detected in 30 of 37 malignant effusions (81%), five of 11 suspected infusions (46%), and five of eight apparently benign effusions (63%). CONCLUSIONS Immunocytochemical staining with anti-83D4 antibody is useful for differentiating reactive or atypical mesothelial cells from epithelial cells, especially in breast cancer effusions.

Abstract
Complement activation products in pleural effusions were studied to clarify the causes of tuberculous and malignant pleuritis. Pleural SC5b-9, an activation product of complement common pathway, was significantly higher in tuberculous effusions than in malignant ones. In the tuberculous effusions, the levels of SC5b-9 and LDH (a marker of tissue damage) were significantly correlated, but in the malignant effusions these two values were not correlated. In the tuberculous effusions, SC5b-9 and Bb values were significantly correlated, but SC5b-9 and C4d were not, and nor were SC5b-9 and immune complex. In the malignant effusions, SC5b-9 and Bb values were low and were not significantly correlated. These results suggest that complement activation plays a significant role in tuberculous pleuritis, but not in malignant pleuritis.

Abstract
Macrophage surrounded by transformed or untransformed lymphocytes is called immune island. Aimming at this problem, we made a survey of 120 pleural and peritoneal effusion smears with a variety of patients and discovered that this island appeared in 52 (43.3%) cases. The positive results existed in 11 of 14 (79%) cases with tuberculosis and 29 of 60 (48%) cases with malignant diseases. The average number of island on each positive smear (2.0cm x 2.5cm) is 59.6 +/- 12.8 in the former and 39.2 +/- 18.9 in the latter. The mechanism of this phenomenon may be due to the response to foreign stimulus from pathogenic and cancer antigen.

Abstract
An enzyme linked immunosorbent assay was set up by using anti-recombinant human interleukin 1 beta monoclonal antibodies. The interleukin 1 beta, anti-interleukin 1 beta autoantibody and interleukin 1 beta containing immune complex were detected in pleural effusion of 28 patients with bacterial infection cases pleurisy and 13 with lung cancer. The results showed that free interleukin 1 beta could be detectable in the early stage of pleurisy, and then transformed to the immune complex. The interleukin 1 beta containing immune complex were detectable in the pleeural effusions of all the 28 patients with pleurisy, but only two patients with lung cancer. The results suggested that this cytokine behaves differently in these two different kinds of diseases.

Abstract
In malignant pleural effusion, lymphocytes (MPEL) and autologous tumor cells (ATC) were obtained by centrifugation on discontinuous density gradients from 16 patients with malignant pleural effusion. The cytotoxicity of MPEL against ATC were compared with that of peripheral blood lymphocytes (PBL). It was demonstrated that the results for separation with 100%: 60% Ficoll-Hypaque which formed a discontinuous density gradients were the best in three sets of discontinuous density gradients. The cytotoxicity of PBL was higher than that of MPEL (P < 0.001), but the cytotoxicity and expansion of MPEL-activated by rIL2 was much higher than that of PBL-activated by rIL2 (LAK cells) (P < 0.001). This shows that local immune reaction within pleural cavity of patients with malignant pleural effusion was in the state of suppression, but the state could be improved by using rIL2. Therefore, we consider that MPEL could be the better effector cells than LAK cells in tumor adoptive immunotherapy.

Abstract
Twenty-two consecutive patients with malignant pleural effusions (MPE) were treated with intrapleural Corynebacterium parvum (CBP) associated with parenteral methylprednisolone (MP) to determine its effectiveness and the frequency and nature of adverse reactions. After thoracentesis, 7 mg of CBP (Coparvax Wellcome) in 20 ml of saline were injected into the pleural cavity. On the day of treatment, the patients were given 1 mg/kg i.m. of MP 30 min before thoracentesis. The effectiveness of pleurodesis was assessed as follows: (1) complete response (CR; total resolution of pleural effusion after 3 injections of CBP at the most); (2) partial response (PR; formation of asymptomatic loculated effusion). In 5 patients leukocytes, lymphocytes and monocytes were determined in pleural fluid (PF) and in blood (B) collected before and 7 days after CBP treatment. Two patients were unevaluable. Of 20 evaluable patients, 18 (90%) had a CR and 2 patients (10%) had a PR. Eleven of 22 patients (50%) had a fever. Three patients had prolonged and/or high fever. Seven of 22 patients (32%) had mild chest pain. None of the patients presented other side effects. Twelve of 21 patients (57.1%) had a PF pH > or = 7.30; 2 of these died a few days after the treatment, and 10 had favorable responses. The other 9 patients had a PF pH < 7.30: all had favorable responses. The leukocytes, the lymphocyte subsets, the monocytes, the NK lymphocytes, and their PF/B ratios did not differ significantly before and after CBP treatment. Our study confirms that intrapleural CBP is an effective and simple method to control MPE.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
There are no known tumor makers of malignant pleural mesothelioma. We measured the concentration of TPA in the pleural effusions from patients with malignant pleural mesothelioma and from patients with other pleural diseases, evaluate its clinical usefulness. The concentration of TPA was more than 7,000 U/l (mean: 18,600 +/- 9,867 U/l, n = 5) in all patients with malignant pleural mesothelioma, but it was less than 4,000 U/l in those with benign asbestos pleurisy and other benign pleural effusion (benign asbestos pleurisy 1,598 +/- 570, n = 5: p < 0.01, tuberculous pleurisy 1.37 +/- 759, n = 11: p < 0.01, others 2,497 +/- 2,152 n = 3: p < 0.05). The concentration of TPA in the pleural effusions was not significantly different between malignant pleural mesothelioma and lung cancer (12,287 +/- 17,070 U/l). However, in all patients with lung cancer and high TPA concentrations, cytologically malignant cells were detected in the pleural effusions. TPA was high in all five patients with malignant pleural mesothelioma, but cytologically malignant cells were detected in only one patient. Only in malignant pleural mesothelioma (not in other benign disease or in lung cancer) was the concentration of TPA more than 4,000 U/l, and no evidence of malignancy was obtained by cytological methods. These findings suggest that assessing TPA in the pleural effusion might contribute to the diagnosis of malignant pleural mesothelioma.

Abstract
We investigated the levels of TGF-beta in malignant pleural effusions (MPE) caused by malignant mesothelioma (MESO) or primary lung cancer. TGF-beta levels in MPE caused by MESO were 283.9 +/- 219.2 pm (mean +/- s.d.) and were three to six times higher than those due to primary lung cancers (P < 0.01 or P < 0.05). We also evaluated TGF-beta 1- and beta 2-like activities in MPE using specific polyclonal antibodies. Although TGF-beta 1-like activity could be detected in all cases, TGF-beta 2-like activities were detected in five of seven in MESO and in a few cases with primary lung cancer. These results demonstrate that the levels of total TGF-beta and TGF-beta 2-like activity may be clinically useful to differentiate MESO from primary lung cancer. Our data also suggest that TGF-beta may help further characterize the clinical features of MESO.
