Steady-state sublimation vapour pressures of anhydrous bismuth trichloride have been measured by the continuous gravimetric Knudsen effusion method from 370.6 to 488.8 K. Additional effusion measurements have also been made from 438.2 to 495.7 K by the torsion effusion method. Based on a correlation of ${\Delta}_H0298$.15 and ${\Delta}_H0298$.15, a recommended p(T) equation has been obtained for BiCl3(s); log(p/Pa)=－C/(T/K)－2.838log(T/K)－8.097${\times}$10-2(K/T)2＋22.588, where p is in Pa, T in Kelvin and ${\Delta}_H0298$.15 in kJmo1-1 and C=(${\Delta}_H0298$.15＋5.9988)/1.9146${\times}$10-2. Condensation coefficients and their temperature dependence have been derived from the effusion measurements.

The study was performed to investigate the comparison of relative signal intensity of normal- and abnormal-side retrodiscal tissue, and relationship between clinical examination, joint effusion and relative signal intensity of retrodiscal tissue in patients with unilateral TMJ internal derangement. The study group comprised 19 females and 9 males, with a mean age of 29 years. After measurements of the signal intensity were made on the MR imager for the T2 weighted images on retrodiscal tissue and brain gray matter, we calculated relative value and tried to find relationship between clinical examination, joint effusion and relative signal intensity on normal- and abnormal-side. The results are as follows. 1. The gray matter is an appropriate reference point. 2. The relative signal intensity is high significantly in abnormal-side retrodiscal tissue compared with normal-side retrodiscal tissue. 3. The relative signal intensity is high significantly in painful joints compared with nonpainful joints and in joints with joint effusion compared with joints without joint effusion. 4. The relative signal intensity in normal joints, joints with reduction and joints without reduction is increased in order significantly.

In Korea. many people enjoy eating raw or underkooked freshwater crayfish and crabs which unfortunately may cause paragonimiasis. Here, we describe a case of pulmonary and abdominal paragonimiasis in a 9-year-old girl, who presented with a 1-month history of abdominal pain, especially in the right flank and the right inguinal area, with anorexia. A chest radiograph revealed pleural effusion in both lungs, and her abdominal sonography indicated an inflammatory lesion in the right psoas muscle. Peripheral blood analysis of the patient showed hypereosinophilia (66.0%) and an elevated total serum lgE level (>2,500 IU/ml). The pleural effusion tested by ELISA were also positive for antibodies against paragonimiasis. Her dietary history stated that she had ingested raw freshwater crab, 4 months previously. The diagnosis was pulmonary paragonimiasis accompanied by abdominal muscle involvement. She was improved after 5 cycles of praziquantel treatment and 2 times of pleural effusion drainage. In conclusion, herein, we report a case of pulmonary and abdominal paragonimiasis in a girl who presented with abdominal pain and tenderness in the inguinal area.

A 3-year-old castrated male Korean domestic short-haired cat (weighing 5.2 kg) was referred to the Kangwon National University Veterinary Teaching Hospital, with primary complaints of ascites, pleural effusion and respiratory distress. Diagnostic studies revealed marked chylous and hemorrhagic pleural effusion, cardiomegaly, restrictive filling pattern of transmitral flow and mitral annular tissue Doppler profiles and minimally thickened left ventricular free wall. Based on the echocardiographic findings, the case was tentatively diagnosed as restrictive cardiomyopathy. The case was treated with removal of pleural effusion and medical therapy including furosemide, enalapril, sildenafil, clopidogrel. This is the first case report of restrictive cardiomyopathy in Korea.

Angiosarcoma is a very rare malignant tumor of endothelial cell origin. We experienced a case of angiosarcoma presented with massive pleural effusion, which was considered as a metastasis from right kidney. A 44-year-old male patient was admitted due to dyspnea for one month. He had a history of transient hematuria 3 months before admission, which disappeared spontaneously. Chest roentgenography showed total haziness in left hemithorax with multiple nodular shadows in right lung. Abdominal ultrasonogram showed a single heterogeneous hyperechoic mass, measuring about $7.3{\times}7.1{\times}6.5cm$ in size in the upper and mid-pole of the right kidney, involving renal sinus. Computed tomography of the chest revealed highly enhanced multiple pulmonary and subpleural nodules with loculated pleurisy. In bronchoscopic finding, a fungating, hypervascular tumor mass was noticed at the orifice of anterior basal segment of left lower lung after removal of tenaceous mucus. Pleural and bronchoscopic biopsies showed findings of angiosarcoma confirmed by immunochemical stains with factor VIII related antigen(+), laminin(+) and vimentin(+), and by characteristic electronmicroscopic findings. Massive pleural effusion was controlled with several times of pleurodesis in both pleural spaces.

We report the patient presented with a left-sided pleural effusion. Pleural fluid analysis revealed lymphocyte-dominant exudates with lower level of adenosine deaminase and negative cytologic malignancy. Thoracoscopic examination and histologic examination revealed metastatic nodules on pleurae, proven to be from the papillary thyroid cancer. There were no other sites of distant metastases. Though papillary thyroid cancer is characterized with slow progression and relatively good prognosis, metastatic pleural effusion as an initial manifestation of undiagnosed papillary thyroid cancer can be considered.

L-thyroxine (LT4) withdrawal prior to radioactive iodine (RAI) ablation therapy is a commonly used method for successful treatment of patients with papillary thyroid cancer (PTC). However, a prolonged period of hypothyroidism induced by LT4 withdrawal is sometimes associated with impaired quality of life and cardiopulmonary dysfunction in PTC patients. Furthermore, LT4 withdrawal may have a trophic effect on residual cancer by means of increased thyrotropin. We report on 2 cases of metastatic PTC patients with malignant pleural effusion (MPE) whose disease showed rapid worsening after LT4 withdrawal and RAI therapy. The first case is a 65-year-old woman who had PTC with multiple distant metastases and MPE. During LT4 withdrawal for RAI therapy, MPE showed rapid worsening, and the patient required repetitive therapeutic thoracentesis. The second case is a 49-year-old woman with PTC who underwent 3 additional operations for cancer recurrence in the neck lymph nodes and 6 times of RAI treatments. While preparing for the $7^{th}$ RAI treatment by withdrawing LT4, she developed MPE which became progressively aggravated after RAI therapy. Both patients experienced increased pleural effusion during the LT4 withdrawal period and a rise in the thyroglobulin level was observed after RAI therapy. MPE was not controlled with therapeutic thoracentesis and pleurodesis. Eventually, both patients died of rapid disease progression after RAI therapy. In summary, LT4 withdrawal may have an adverse effect on metastatic PTC patients, particularly those with MPE.

Background: Toll-like receptors (TLRs) detect microbial infection and can directly induce innate host defense responses, which are thought to play critical roles in protecting the tubotympanum from infection. However, little is known about the relationship between TLRs, which are related to innate immunity, and immunoglobulins, which are related to adaptive immunity, in recurrent otitis media with effusion (OME). We therefore investigated the expression of TLR2 and TLR4 and immunoglobulin in children with OME. Methods: The study population consisted of 72 children with OME, 31 with more than 4 episodes in 12 months or more than 3 episodes in 6 months (otitis-prone group), and 41 with fewer than 3 episodes in 12 months (non-otitis prone group). The expression in middle ear effusion of TLR2 and TLR4 mRNA, as determined by Real time- -polymerase chain reaction (RT-PCR), and the concentrations of IgG, IgA, and IgM, as determined by Enzyme-linked immunosorbent assay(ELISA), were compared between the two groups. Results: Expression of TLR2 and TLR4 mRNA was lower in the otitis prone than in the non-otitis prone group, but the difference was not statistically significant (p>0.05). Between group differences in the concentrations of IgG, IgA and IgM in effusion fluid were not significant (p>0.05), and there were no correlations between immunoglobulin concentration and the expression of TLR2 and TLR4. Conclusion: Although there was a trend toward lower expression of TLR2 and TLR4 in the otitis-prone group, the differences, and those in immunoglobulin concentration, did not differ significantly between the otitis-prone and non-prone groups.

The author measured IL-2, IL-4, IL-6, TNF-${\alpha}$ and total protein(TP) level of middle ear effusion(MEE) of 24 ears - 13 ears of them had treated by antibiotics, 11 of them by Kami-hyunggyeyungyotang - of pediatric recurrent otitis media with effusion(PROME) using ELISA assay, and compared the level of cytokines(pg/ml)/TP(mg/dl). And investigated the clinical finding in those children. The results were obtained as follows: 1. The level of IL-2／TP in Kami-hyunggyeyungyotang group was significantly higher than that in antibiotics group(P〈0.05). 2. The level of IL-4/TP in Kami-hyunggyeyungyotang group was significantly higher than that in antibiotics group(P〈0.0l). 3. The level of IL-6/TP in Kami-hyunggyeyungyotang group was significantly lower than that in antibiotics group(P〈0.05). 4. The level of TNF-${\alpha}$/TP in Kami-hyunggyeyungyotang group was significantly lower than that in antibiotics group(P〈0.01) 5. 79.1% of children with recurrent otitis media with effusion(ROME) were also complicated to chronic sinusitis. The children's t-test was used to make a statistical comparison between the groups. According to above results, Kami-hyunggyeyungyotang is considered to be used for treatment 'recurrent otitis media with effusion' by control produce of cytokines which are connected with inflammatory reaction.

We report a case of malignant pericardial effusion originated from adenocarcinoma of the lung incidentally diagnosed by bone scintigraphy, prior to echocardiographic detection. A 76 year-old man with adenocarcinoma of the lung underwent Tc-99m MDP bone scintigraphy to evaluate skeletal metastasis. Anterior images of the chest of the bone scintigraphy unexpectedly showed diffuse increased activity in the region of the heart surrounded by an oval-shaped band of increased activity corresponding to the periphery of the cardiac silhouette (Fig. 1). There was no evidence of bony metastasis. Pericardial effusion was confirmed by echocardiography (Fig. 2) and malignant cells were revealed by subsequent microscopic examination of the pericardial fluid. Bone scintigraphy using Tc-99m phosphate compounds is commonly used to detect bony metastasis in cancer patients. Tc-99m phosphate compounds occasionally accumulate in extra-osseous sites, including $pleural^{1,2)},\;pericardial^{3,4)},\;and\;ascitic\;fluids^{5,6)}$. It has been reported that their accumulation in serous effusions should strongly suggest $malignancy^{1-6)}$. The exact mechanism for accumulation of Tc-99m phosphate compounds in serous effusions is unclear. Several investigators have proposed that the radiopharmaceuticals exuded directly from peripheral vessels to the serous cavity due to increased vascularity and vascular permeability, and bleeding by disruption of blood vessels due to cancerous $infiltration^{5,6)}$.
