Pleurisy, an inflammation of the lining around the lungs, is associated with a common complication of several different medical conditions, the most pervasive being viral and mycobacterial infections. We evaluated the relevance of pleurisy and high blood pressure, diabetes. This study is a survey of 136 patients in whom pleural aspiration was performed to confirm the relationship with hypertension or diabetes mellitus and pleurisy. In the 136 patients, 47.8% were normal people (without hypertension and diabetes mellitus), 32.3% were hypertension patients, 7.4% were diabetes mellitus patients, and 12.5% were patients with hypertension and diabetes mellitus. Odds ratio of normal and hypertension group by pleurisy was 2.524 and the confidence interval was 1.050, 6.069, odds ratio of normal and hypertension group was 4.417 and the confidence interval was 1.101, 17.714. According to these results, hypertension and diabetes mellitus may increase the risk of pleurisy.

Immunotherapy has been used in support of trimethoprim-sulfamethoxazole treatment for Pneumocvstis corinii pneumonia. The present study investigated the therapeutic or preventive effects of heterogeneous hyperimmune IgG antibody (HIA) in experimental rats. Their immunity was suppressed by steroid injection, and they were also injected peritoneally with HIA which reacted with 40-55, 92, 116, and 200 kDa bands of the crude antigen. All rats were infected by p. ccrinii and the cystic forms on lung impression smears were counted. The count was 20.5-76.5 (mean 52.5 ± 19.)1 in those which received steroid only, but decreased to 6.0-21.0 (mean 13.5 : 10.6) in those of group 3 which received HIA for the same duration. In other groups, the mean count ranged from 29.9 t 32.9 to 54.1 t 47.7, and in those which received 13.7 mg HIA the reduction effect was greater than in those which received 6.8 mg or 20.5 mg HIA. The present finding confirmed that in rats during the early stage of infection, the heterogeneous HIA to MSG antigen bands had a partial effect on p. cori,nii pneumonia, both prophylactically and therapeutically.

This paper dealt with the clinical and pathological observations on the experimental rabbit viral hepatitis. Rabbits with 2-14 months of ages were intramuscularly inoculated with virus suspension. The results were summarized as follows. Ninety percents of experimental rabbits inoculated with virus died within 96 hours postinoculation. Common clinical signs were inappetence, increase in body temperature, depression, mild diarrhea and in three cases, bloody foam from nostrils was recognized. At necropsy, in most of the experimental cases, there were hyperemia or haemorrhages in many organs and pale liver. Intestinal catarrh and retention of turbid urine in urinary bladder were seen in some cases. Histopathologically, liver necrosis was found in all the cases died of this disease. However, there was a difference in the severity of hepatic necrosis. Haemorrhages were Iecognized in lungs, heart, liver, spleen, kidneys and thymus, in order. Liver necrosis was marked even in the cases with no haemorrhage. Perivascular cuffing in brain and catarrhal enteritis in small intestine were seen in many cases. From these results, consistent and primary lesion in this viral disease is hepatitis in susceptible rabbits. It was concluded that rabbit hepatitis virus might have the properties of hepatotropism and consequently induce peripheral necrosis in the liver leading to acute viremia with haemorrhages.

Production of circulating specific antibodies to the lung fluke (Paragenimus westermani) by its host is well known and used in various kinds of immunodiagnostic methods, However, it has not been well documented which compartments (or structures) of the lung fluke are most responsible for the production of specific antibodies. The present immunohistochemical study was undertaken to demonstrate the antigenicity of each body compartment of p. westermani such as suckers, tegument, spines, vitelline glands, intestine, reproductive organs(male and female), and eggs. Indiret immunoperoxidase(IP) stain technique was applied, using formalin-fked, paraffin- embedded lung tissues of P westermani-infected cats sectioned in 4 Um thickness as the antigen and cat antisera (11~20 weeks of infection) as the primary antibody. Peroxidase-conjugated goat anti-cat IgG was used as the secondary antibody and diaminobensidine(DAB) as the coloring agent. Strong yellow or yellowish brown staining was regarded positive. The primary and secondary antibody dilutions were made at 1 : 500~1 : 2, 000 and 1 : 200~1 : 500 respectively, and IP stain was repeated 10 times for each dilution. A consistent result obtained was that the intestinal epithelial border, intestinal content, vitelline glands, and eggs scattered around the worm capsule showed strong positive staining, while uterine eggs and some parenchymal portions showed weak positive reaction. On the other hand, the suckers, tegument, spines, subtegumental cells, cytoplasm of intestinal epithelial cells, male reproductive organs, and ovary revealed negative staining. The body compartments showing higher antigenicity were, in the decreasing order, the intestinal epithelial border, intestinal content, eggs in the worm capsule, vitelline glands, uterine eggs, and parenchymatous portions. The intestinal epithelial border and luminal contents revealed positive staining even at a few concentration of 1 : 4, 000 primary antibody(secondary ab., 1 : 200) whereas the parenchymatous portion showed positive reaction only at higher concentrations than 1'500 (secondary ab., 1 : 200). The results suggest that the specific antibody responses of the host to p. westermani occur most strongly upon the excretes from the intestinal epithelium of the worm and e99s Produced around the worm capsule,

Purpose : Atopic findings may be associated with severity of pneumonia in 2009 pandemic influenza A (H1N1) infection, which could suggest a possible association between atopic findings and the severity of viral infections. Thus, we studied association between atopic findings and severity of disease in children with H1N1 influenza infection. Methods : A retrospective study was performed in 74 children admitted in a single tertiary institute and confirmed as H1N1 patients by reverse transcriptase (RT) - polymerase chain reaction (PCR). They were divided into 2 groups according to the severity of pneumonia. We evaluated whether the atopic finding is risk factor between the two groups. Results : Children with severe pneumonia had higher percentages of serum eosinophilia (88% vs 40%, P <0.001), asthma (65% vs 35%, P =0.011), allergic rhinitis (71% vs 40%, P =0.009), and IgE level (P =0.007). We found positive correlations between aeroallergen sensitizations and severity of pneumonia (82% vs 53%, P =0.007). Conclusion : Among patients with H1N1 pneumonia, asthma and atopic findings are risk factors for severity of pneumonia.

Bronchiolitis obliterans is a clinical syndrome of chronic obstruction associated with inflammatory changes in the small airways. There are marked variations in the epidemiology of this disease. In childhood, bronchiolitis obliterans has been described as a result of a number of infections such as adenovirus, measles, Bordetella pertussis, Mycoplasma pneumoniae, and influenza A infection. Most common agents are adenovirus types 3, 7, and 21. Diagnosis of bronchiolitis obliterans can be made based on clinical findings, high resolution computed tomography (HRCT) and lung biopsy. In addition to diagnosis, treatment is not yet clearly established. The authors experienced a case of bronchiolitis obliterans developed in 3 year-old girl who suffered from type 7 adenoviral pneumonia. She had been hospitalized and treated for 15 days due to pneumonia. After discharge, productive cough was not improved and auscultation revealed wheezing. HRCT demonstrated multifocal mosaic patterns suggesting bronchiolitis obliterans. She was managed with inhaled steroid and bronchodilator, and her symptoms were improved. However, follow up HRCT showed no interval change.

A broad spectrum of antibiotic action was studied with Centipedin purified from centipede Scolopendra subspinipes multilans L. Koch aganist gram-positive, gram-negative bacteria and fungi. The minimal inhibitory concentrations(MICs) were determined in liquid medium. The significant antibiotic activity was obtained aganist gram-negative Klebsiella pneumoniae ATCC 8308 responsible for causing infection at lung and intestine. The MIC value against Klebsiella pneumoniae ATCC 8308 was $2{\mu}g/ml$, and this Centipedin was active against Proteus vulgaris NRRL B-123. In addition, it has been shown that Centipedin blocks procaryotic RNA transcription and a little of DNA replication system in vitro. Centipedin did not exhibit any significant cytotoxicity against animal cells such as human blood leukemia (HL-60) and mouse B lymphocyte myeloma cell.

배경: 본 연구는 1987년부터 1997년까지 원자력병원에서 수술을 시행한 500명의 식도암환자를 대상으로 하여 휴향적 방법을 통해 조기 및 장기성적, 재발양상, 예후인자 등을 보고하고자 한다. 대상 및 방법: 대상환자 중에서 발병암이 있는 경우, 인두식도 경계부위나 위식도 경계부위 암, 고식적 우회술 또는 인공식도 삽입예 그리고 시험적 개흉술이나 개복술 만을 시행한 경우는 제외 시켰다. 식도 절제는 대부분 우측 개흉술을 이용한 Ivor Lewis 술식을 사용하였고 대부분의 문합은 stapler를 사용하였다. Extended lymph node dissection은 1994년 8월부터 시행하였고 그 이전에는 standard lymph node dissection을 하였다. 96.8%에서 위를 식도 대체장기로 사용하였고 경부에서 절제 및 재건술을 시행한 경우를 제외한 모든 식도재건은 후종격동을 통해 시행하였다. 결과: 474예(94.8%)가 편평상피 세포암이었고 대부분(58.2%)은 중부식도에 위치하였다. 술후병기는 47.4%가 stage III이었고 25%가 stage IIA이었다. 392예에서 근치적 절제가 가능하였고 74예는 고식적 절제를 시행하였으며, 식도열공을 통한 식도절제술과 경부에서의 유리공장 이식술을 시행한 34예는 위분류에서 제외하였다. 술후 유병율은 38.4%이었고 수술 사망률은 5.8%로 호흡기 감염, 문합부 유출이 주요 원인이었다. 대상환자의 99.8%에서 추적은 가능하였고 수술사망 예를 포함한 전체환자의 1, 2, 5년 생존율은 각각 63.5%, 38.9%, 19.4% 이었다. Standard lymph node dissection 그룹에서의 1, 2, 5년 생존율이 60.7%, 35.9%, 16.9%이었으나 extended lymph node dissection그룹에서는 1, 2, 4년 생존율이 70.2%, 46.5%, 30.9%이었다. 근치적 절제의 경우는 1, 2, 5년 생존률이 69.4%, 43.9%, 21.9%이었고, 고식적 절제의 경우는 37.8%, 17.6%, 7.3%이었다. 수술사망을 제외한 근치적 절제술과 extended lymph node dissection을 함께 시행한 경우의 4년 생존율은 35.6%이었다. 수술후 재발은 226예에서 발견되었고 주로 국소임파절(69%; 경부, 종격동, 복부)이었으며, 전신재발은 간, 폐, 뼈, 뇌 등의 순이었다. 결론: 저자들은 적절한 술후 환자관리가 선행되어야 하지만 근치적 절제와 광범위한 임파절 절제가 장기성적의 향상에 필수적 요소이고, 진행된 식도암에 있어서는 보다 효과적인 보강적 복합치료가 연구되어야 할 것으로 생각된다.

Aspergillus Infection is a major.cause of mortality in individuals with depressed cell-mediated immunity. Despite therapy with intravenous amphotericin B and oral antifungal agents, high mortality has been reported among heart transplant recipients. We experienced two cases of pulmonary aspergillosis among 15 heart transplantation cases. Both cases were similiar in terms of age, time of diagnosis, and medication. Percutaneous needle aspiration biopsy revealed Aspergillus fumigatus in both cases. The thirst case showed multiple aspergilloma on both lung fields and were treated by IV Amphotericin B and oral itraconazole. After completion of treatment, the lesion completely disappeared and he has been followed up for more than one year in his good condition. The second case showed a single nodule on his right lower lung field and were treated by both medication and surgery. The patient recovered well and had been doing well until 4th postoperative month when he developed humoral rejection and expired.

Most cases of eosinophilic pneumonia reported previously have followed a chronic course. The case presented here was acute in onset, suggesting a acute eosinophilic pneumonia. A model of criteria for acute and chronic eosinophilic pneumonia was made by Umeki in 1992. A previously healthy young man presented with cough, sputum, fever, and multiple small nodules on the chest radiograph. We confirmed eosinophilic pneumonia with bronchoalveolar lavage analysis and transbronchial lung biopsy. This case examplifies the recently descrived acute eosinophilic pneumonia.
