An 11-year-old intact female miniature poodle presented with a four-month history of hemorrhagic effusion. The patient was alert on physical examination, although muffled heart sounds were noted upon auscultation of the right hemithorax. The radiographic finding was pleural effusion. Ultrasonography revealed cystic changes in both ovaries and several nodules in the liver. A refractory opacity in the right lung field, as visualized with computer tomography (CT), was diagnosed as right middle lung lobe torsion with a collapsed bronchus. Five days after diagnosis, a right fifth intercostal thoracotomy was performed to remove the right middle lung lobe; the right middle lung lobe was grossly shrunken as a result of chronic lung lobe torsion. Ovariohysterectomy was also performed. Histopathologic examination revealed papillary adenocarcinoma in both ovaries and suspected metastasized ovarian adenocarcinoma cells in the lung lobe. The patient recovered favorably and had been doing well up to two months post-surgery. However, after four months, the dog presented with respiratory difficulty. The radiographic findings were pleural effusion and collapse of the right cranial and left caudal lung lobes. Malignant cells of epithelial origin were observed in the pleural effusion. The tumor cells were suspected to be metastasized cells from the previously resected lung lobe. Although cancer treatment was recommended, the suggestion was suspended and the dog was discharged from hospital. This was a case of lung lobe torsion that had occurred because of hemorrhagic effusion due to tumor. Although ovariohysterectomy and lobectomy were performed, there was a relapse of hemorrhagic effusion because of metastasized tumor from the previously resected lung lobe.

Certain hexavalent chromium compounds when administered via inhalation have the potential to induce lung injury in human and experimental animals. In present study, the inhalation effect of hexavalent chromium on morphological change and weight change of rat organ were investigated. Rats were exposed to hexavalent chromium ($Na_2CrO_4{\cdot}4H_2O$) at concentration of $0.36mg/m^3$ (group 1), $1.8mg/m^3$ (group 2), ascorbic acid and $1.8mg/m^3$ (group 3) and filtered air (group 0, control group) for I week, 2 weeks and 3 weeks. The weight of lung and kidney in group 2 and group 3 significantly higher than in control group at same exposure period. The epithilial cells of bronchiole in group 1, 2, 3 were more flatten than group 0. In the lung, the number of macrophage was significantly increased and morphologically changed macrophages were observed in group 1, 2, 3. The morphological change of the lung did not significant between group 2 and group 3, however, in group 1 was milder than in group 2 and group 3. The severity of morphological change were depend on exposure period in the lung. The morphological changes by hexavalent chromium of the liver and kidney were also observed These results suggest that inhalation of hexavalent chromium effects on not only respiratory organ, but also the liver and the kidney via blood stream.

This study was designed to investigate the effect of a butanol (BuOH) fraction of Alisma canaliculatum (Ac) with/without vitamin E (VE) on glycogen, lipid levels and oxidative stress in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were divided into 5 groups: normal, STZ-control, and 3 diabetic experimental groups. Diabetes was induced by injection of STZ (45 mg) into the tail vein. The BuOH fraction of Ac and VE were administrated orally in rats for 21 days: Ac group (400 mg), Ac-VE group (Ac 400 mg & vitamin E 10 mg) and VE group (10 mg). Liver and muscle glycogen levels decrease in STZ-control group versus normal group and these alteration in glycogen levels were prevented Ac-VE group and VE group. Oral administration of Ac or VE resulted in reduction in liver cholesterol. Liver triglycerides were significantly higher in the VE group than in STZ-control group. Liver malondialdehyde (MDA) was increase in STZ-control group compared to normal group, but that of Ac group and Ac-VE group were similar to normal group. Meanwhile MDA in kidney, lung and pancreas were not significantly different among five groups. Ac-VE group increase lung protein that were significantly higher than diabetic control rats. These results suggest that the VE could increase glycogen and triglyceride levels and BuOH fraction of Ac decrease MDA of liver in the diabetic rats. The use of Ac together with VE did not show better control hyperglycemia-induced oxidative stress.

Among oriental medicine,s literatures, through Hwang-Je-Nae-Kyung(黃帝內徑) to Chung(淸), I extracted contents related to atrophy syndrome(?證). And studied it,s pathophysiology, therapy and treatment. Then, I concluded that result same below 1. The pathophysiologies of atrophy syndrome are lung heat(肺熱) & decreasing of it,s circulation, making liver and stomach weaken & difficulty it's circulation, injurious to liver and kidney & atrophy of bonemarrow and muscle. 2. The most important point of atrophy syndrome therapy is Yang-Myung(陽明). The Priority of therapy is stomach & liver,s balance. And then we must protect acquired human function & clean humidity & temperature of Yang-Myung(陽明). under the principle of decreasing south organ,s function & protecting north organ,s function, we should Ja-Yeum-Chung-Yeul(滋陰淸熱). so remove temperature of lung & protect liver and kidney & make strong stomach. 3. Among the therapy of atrophy syndrome in literatures Yi-Jin-Tang(二陳湯), Sa-Gun-Ja-Tang(四君子湯), Sa-Mul-Tang-Je(四物湯劑), Ho-Jam-Hwan(虎蠶丸), Dong-Won-Geun-Bo-Hwan(東垣健步丸) and Chung-Jo-Tang(淸燥湯) were many. These make strong spleen & dry humidity organ using Sa-Gun-Ja-Tang(四君子湯)and Yi-Jin-Tang(二陳湯) by Dog-Cheu-Yang-Myung(獨取陽明) method. Sa-Mul-Tang(四物湯), Phellodendri cortex(黃柏), Radix sophorae flavescentis(苦蔘), Carapax Testudinis(龜板) bitter taste make strong Yeum(陰) & decrease Yang(陽) so important human muscle powerful. Ho-Jam-Hwan(虎蠶丸), Dong-Won-Geun-Bo-Hwan(東垣健步丸), Chung-Jo-Tang(淸燥湯) make Chung-Yeul-Jo-Seup(淸熱燥濕), protect liver and kidney & strong muscle and bone. Besides Gum-Gang-Hwan(金剛丸), Yi-Myo-Hwan(二妙丸), Nok-Gak-Geu-Hwan(鹿角膠丸)&Ga-Mi-Sa-Geun-Hwan(加味四斤丸) were used in treatment of atrophy syndrome.

Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.

A 70-year-old female diagnosed with pancreatic ductal adenocarcinoma was treated by pylorus-preserving pancreaticoduodenectomy (PPPD) and adjuvant concurrent chemoradiotherapy with 5-fluorouracil. Pancreatic ductal adenocarcinoma pT3N0 (stage IIA) was pathologically confirmed. Abdominal computed tomography (CT) findings 14 months after PPPD showed 10 mm sized solitary liver metastasis in segment 3. After 12 cycles of gemcitabine and 9 cycles of capecitabine plus oxaliplatin, the metastatic nodule increased in size to 27 mm. Tumorectomy at segment 3 of liver was done. 25 months after tumorectomy, chest CT showed 23 mm sized cavitary nodule in right upper lobe of lung. The result of percutaneous biopsy favored metastatic adenocarcinoma. Two sets of stereotactic body radiation therapy were done and the patient has survived without further disease progression for 6 years after initial diagnosis. This case suggests that selected population of recurrent pancreatic cancer patients with solitary liver or pulmonary metastasis can be treated by resection of metastatic site and ablative therapies.

Hitiocytosis X, recently termed Langergans cell histiocytosis, is a rare disease histologically characterized by an abnormal proliferation of histiocytes, and of which the pathophysiology is still ambiguous. The clinical presentation is highly varied. Typically, there is a solitary or multiple bony involvements, and less frequently, lesions are found in other organs such as the lungs, liver, lymph nodes, skin, and mucosae. Interestingly, so far, there has been no report which shows multiple developments in both soft and hard tissues. In this report, we present a case of hitiocytosis X in both mandible and lung. This may provide some information for understanding the pathophysilogy of the histiocytosis X.

Fibrosis is characterized by excessive accumulation of extracellular matrix components. The fibrotic process ultimately leads to organ dysfunction and failure in chronic inflammatory and metabolic diseases such as pulmonary fibrosis, advanced kidney disease, and liver cirrhosis. Idiopathic pulmonary fibrosis (IPF) is a common form of progressive and chronic interstitial lung disease of unknown etiology. Pathophysiologically, the parenchyma of the lung alveoli, interstitium, and capillary endothelium becomes scarred and stiff, which makes breathing difficult because the lungs have to work harder to transfer oxygen and carbon dioxide between the alveolar space and bloodstream. The transforming growth factor beta (TGF-β) signaling pathway plays an important role in the pathogenesis of pulmonary fibrosis and scarring of the lung tissue. Recent clinical trials focused on the development of pharmacological agents that either directly or indirectly target kinases for the treatment of IPF. Therefore, to develop therapeutic targets for pulmonary fibrosis, it is essential to understand the key factors involved in the pathogenesis of pulmonary fibrosis and the underlying signaling pathway. The objective of this review is to discuss the role of kinase signaling cascades in the regulation of either TGF-β-dependent or other signaling pathways, including Rho-associated coiled-coil kinase, c-jun N-terminal kinase, extracellular signal-regulated kinase 5, and p90 ribosomal S6 kinase pathways, and potential therapeutic targets in IPF.
