BACKGROUND: It is now thought that the earliest manifestation of idiopathic pulmonary fibrosis is alveolitis, that is, an accumulation of inflammatory and immune effector cells within alveolar walls and spaces. Inflammatory cells including alveolar macrophages and resident normal pulmonary tissue cells participate through the release of many variable mediators such as inflammatory growth factors and cytokines, which contribute to tissue damage and finally cause chronic pulmonary inflammation and fibrosis. This study was performed to investigate the source and distribution pattern of transforming growth factor-beta1(TGF-beta1), platelet derived growth factor(PDGF), basic fibroblast growth factor(bFGF), interleukin 1(IL-1), interleukin 6(IL-6), tumor necrosis factor-alpha(TNF-alpha) and the role of these mediators on bleomycin(BLM)-induced pulmonary injury and fibrosis in rats. METHOD: Wistar rats were divided into three groups(control group, BML treated group, BML and vitamine E treated group). Animals were sacrifices periodically at 1, 2, 3, 4, 5, 7, 14, 21, 28 days after saline or BLM administration. The effects were compared to the results of bronchoalveolar lavage fluid analysis, light microscopic findings, immunohistochemical stains for six defferent mediators(TGF-beta1, PDGF, bFGF, IL-1, IL-6 and TNF-alpha) and mRNA in situ hybridization for TGF-beta1. RESULTS: IL-1 and IL-6 are maximally expressed at postbleomycin 1~7th day which are mainly produced by neutrophils and bronchiolar epithelium. It is thought that they induce recruitment of inflammatory cells at the injury site. The expression of IL-1 and IL-6 at the bronchiolar epithelium within 7th day is an indirect evidence of contribution of bronchiolar epithelial cells to promote and maintain the inflammatory and immune responses adjacent to the airways. TNF-alpha is mainly produced by neutrophils and bronchiolar epithelial cells during 1~5th day, alveolar macrophages during 7~28th day. At the earlier period, TNF-alpha causes recruitment of inflammatory cells at the injury site and later stimulates pulmonary fibrosis. The main secreting cells of TGF-beta1 are alveolar macrophages and bronchiolar epithelium and the target is pulmonary fibroblasts and extracellular matrix. TGF-beta1 and PDGF stimulate proliferation of pulmonary fibroblasts and TGF-beta1 and bFGF incite the fibroblasts to produce extracellular matrix. The vitamine E and BLM treated group shows few positive cells(p<0.05). CONCLUSION: After endothelial and epithelial injury, the neutrophils and bronchiolar epithelium secrete IL-1, IL-6, TNF-alpha which induce infiltration of many neutrophils. It is thought that variable enzymes and O2 radicals released by these neutrophils cause destruction of normal lung architecture and progression of pulmonary fibrosis. At the 7~28th day, TGF-beta1, PDGF, bFGF, TNF-alpha secreted by alveolar macrophages sting pulmonary fibroblasts into proliferating with increased production of extracellular matrix and finally, they make progression of pulmonary fibrosis. TNF-alpha compares quite important with TGF-beta1 to cause pulmonary fibrosis. Vitamine E seems to decrease the extent of BLM induced pulmonary fibrosis.

A clinical study was made on 85 cases of prematurity under 37 weeks of gestational age who had history of blood transfusion during their admission at the National Medical Center from January 1989 to June 1992. The results were as follows: 1) Among 339 prematurity patients, 85 patients(25.1%) received blood transfusion once at least. 2) Male to female ratio was 1.13:1 and mean gestational age was 32.5 2.7weeks (range:25~36 weeks). 3) Most of blood transfusion(66/85 cases) were performed within first week of life. 4) 67 patients(78.8%) received blood transfusion 3 times or less. 5) Combined diseases were hyaline membrane disease(69.4%), jaundice(51.8%), sepsis(30.6%), PDA (14.1%), DIC (8.2%), pulmonary hemorrhage(7.1%), intraventricular hemorrhage (7.1%), pneumonia(7.1%) and hepatitis(4.7%). 6) Clinical manifestations at the time of blood transfusion were pallor (47.1%), decreased activity (44.7%), bradycardia (23.5%),apnea (21.2%), tachypnea (20.0%), lethargy (4.7%), poor weight gain (3.5%) and tachycardia (3.5%). 7) The values of hematocrit were significantly increased after transfusion(42.4 +/-7.2 vs 34.6 +/- 6.8vol%). 8) The episodes of bradycardia were significantly decreased after blood transfusion(0.09 +/- 0.39 vs 0.23+/- 0.78)while the episodes of apnea were not (0.15 +/-0.71 vs 0.27+/- 0.84).

This experiment was focused on the characterization of anti-Toxoplasma monoclonal antibodies (mAbs) and the effect of mAbs on the parasite invasion of mouse peritoneal macrophages. Twenty eight mAbs including M110, M556, R7A6 and M621 were characterized by Ab titer, immunoglobulin isotyping and western blot pattern. Antibody titer (optical density) of 4 mAbs, M110, M556, R7A6 and M621, were 0.53, 0.67, 0.45 and 0.39 (normal mouse serum; 0.19) with the same IgG1 isotypes shown by Enzyme-linked immunosorbent assay (ELISA). Western blot analysis showed that M110, M556, R7A6 and M621 reacted with the 33 kDa (p30), 31 kDa (p28), 43 kDa and 36 kDa protein. Immunogold labelling of mAbs M110, M556, R7A6 and M621 reacted with the surface membrane, dense granules and parasitophorous vacuolar membrane (PVM), rhoptries and cytoplasm of tachyzoite, respectively. For in vitro assay, preincubation of tachyzoites with four mAbs, M110, M556, R7A6 and M621 resulted in the decrease of the number of infected macrophages (P < 0.05) and the suppression of parasite multiplication at 18 h post-infection. Four monoclonal antibodies including M110 (SAG1) were found to have an important role in the inhibition of macrophage invasion and T. gondii multiplication in vitro, and these mAbs may be suitable for vaccine candidates, diagnostic kit and for chemotherapy.

PURPOSE: In this study we analyzed and compared the orbital anatomy in Korean and Caucasian subjects using computed tomography (CT) measurements. METHODS: Two observers performed a cross-sectional, retrospective analysis of 44 CT scans of subjects (22 Koreans, 22 Caucasians) with no appreciable orbital or globe disease. Ten length measurements and 3 angle measurements of various orbital aspects were obtained. Analysis was performed to determine if changes in these parameters were associated with race. RESULTS: Anterior medial interorbital length was 24.05 +/- 2.00 mm in Korean and 21.96 +/- 1.96 mm in Caucasian subjects. Anterior vertical orbital length was 34.19 +/- 1.67 mm in Korean and 35.03 +/- 1.18 mm in Caucasian subjects. The anterior medial interorbital length and anterior vertical orbital length (p < 0.05) were significantly different. Interorbital angle was 47.69degrees +/- 1.49degrees in Korean and 46.15degrees +/- 2.19degrees in Caucasian subjects; the difference was statistically significant (p < 0.05). CONCLUSIONS: Compared with Caucasians, the orbit of Korean subjects has a narrower orbital opening and longer interorbital distance. The present study regarding the anatomy of Korean and Caucasian orbits will assist physicians with the evaluation and treatment of orbital diseases.

Adenomatoid tumor of the uterus is a rare benign neoplasm which has been known as mesothelial origin. Characteristically, it appears as a small nodular lesion less than 2.0cm in the myometrium of subserosal region. We describe a case of giant adenomatoid tumor of the uterus having multicystic gross appearance. A 49-year-old woman complained of vaginal bleeding. The tumor was an intramural mass with maximum diameter of 10 cm and located at posterior wall of the uterus. Histologically, the tumor was composed of multiple cystic cavities of variable size lined by flattened cells, lying among thin septa of connective tissue. Immunohistochemically, the cells are positive for low molecular weight cytokeratin(CAM 5.2) and are negative for factor VIII.
