  • IL-10 is an important anti-inflammatory cytokine that can inhibit the production of many pro-inflammatory cytokines. Both human and animal studies have shown that pro-inflammatory cytokines play an important role in pneumonia and other inflammatory lung diseases. In the present study, IL-10 knockout(KO) and wild-type mice were infected with Corynebacterium kutscheri to determine whether the severity of pathogenesis and whether protective immunity could be altered in the absence of IL-10. The survival rate was significantly lower in IL-10 KO mice than wild-type mice. The number of neutrophils in bronchoalveolar lavage fluid and blood were found to be higher in IL-10 KO mice than wild-type mice. IL-10 KO mice showed greater neutrophil infiltration, excessive inflammation, and weight-loss compared with wild-type mice. Furthermore, upregulation of IFN-$\gamma$ in bronchoalveolar lavage fluid, and upregulation of MIP-$1{\alpha}$ and IP-10 mRNA in the lungs of IL-10 KO mice compared with wild-type mice after C. kutscheri infection were observed. These results suggest that IL-10 plays an important role in the anti-inflammatory properties against C. kutscheri infection, and that lack of IL-10 leads to a more severe pulmonary inflammatory response. This increased susceptibility to C. kutscheri pneumonia is at least in part caused by IL-10 deficiency and severe recruitment of neutrophils.

  • Oroxylum indicum has long been used in Asian traditional medicine to prevent and treat respiratory diseases, diabetes, diarrhea and other conditions. Oroxylin A is a flavone that is present in Oroxylum indicum and in Scutellaria baicalensis. Because the root extracts of both plants have been shown to have anti-allergic effects, the authors investigated whether oroxylin A is likely to have beneficial effects on allergic asthma using female Balb/c mice and rat RBL-2H3 mast cells. Antigen-induced degranulation was measured in vitro by measuring b-hexosaminidase activity. A murine ovalbumin-induced allergic asthma model was used to test the in vivo efficacy of oroxylin A. Sensitization and challenge of ovalbumin induced allergic asthma responses, the accumulations of eosinophils and Th2 cytokine levels in bronchoalveolar lavage fluid and lung tissues. Oroxylin A administration decreased numbers of inflammatory cells, especially eosinophils, and reduced the expression and secretion of Th2 cytokines, including IL-4 and IL-13, in lung tissues and bronchoalveolar lavage fluid. Histologic studies showed oroxylin A reduced inflammatory signs and mucin production in lungs. These findings provide evidence that oroxylin A has potential use as an anti-allergic therapeutic.

  • A 4-year-old, neutered male Shih-tzu dog weighing 5.4 kg was referred due to anorexia and chronic coughing. Based on history, physical examination, laboratory tests, radiographic findings, echocardiography, and bronchoscopic examination, the dog was diagnosed as tracheobronchial foreign body. The foreign body was steamed rice debris, which was removed by bronchoalveolar lavage (BAL) with vacuum suction of bronchoscopy. Bacterial and fungal culture of collected BAL fluid was negative. Baermann test for lungs parasites also was negative. The dog was treated with bronchodilator, antibiotics, anti-inflammatory agent, and mucolytics for 7 days. Appetite increased and coughing sign was clearly improved after removal of foreign body and medical therapy. This case report describes that bronchoscopic techniques are available for the evaluation and management of airway foreign bodies.

  • Ischemia reperfusion injury occurs in various diseases. The role of oxygen free radicals in IR injury of the lung has been spotlighted and many studies have been performed. In this study, we tried to prepare a stable rat lung model for IR injury, focusing on surrounding conditions as hilar stripped left lung, clamped left pulmonary artery and bronchus,and declamped after determined period was passed, and right main pulmonary aretery was clamped. Arterial blood gas analyes were performed at 1, 10, 20, 30, minutes after reperfusion. Before clamping, PaO2 was 95 to 120 mmHg in all animals. There were six groups; Group I : temperature 15o C, and 120 minutes clamping, Group II: 20 oC, and 120 minutes clamping, Group III : 25 oC, and 120 minutes clamping, Group IV : 15oC, 90 minutes clamping, Group V : 20 oC, 90 minutes clamping,Group VI: 20 oC, 75 minutes clamping. Each groups contained 10 Sprague Dayley rats. The humidity was maintained 100 % as circulation imerged isotonic Hartmann`s solution of the pleural cavity. In group IV, V, and VI, PaO2 decreased significantly in all animals immediately after reperfusion, but 43 % survived till 10 minutes after reperfusion, it was 74.0$\pm$5.7, 73.3$\pm$10.8,and 88.2$\pm$17.7 mmHg. Pulmonary edema was observed histologically in 2/10 animals in group IV, 6/10 in group V , 3/10 in group VI, 9/10 in group I, and the other lungs showed all edema. We established a stable model by setting ischemic time,and temperature, between 75 to 90 minutes,15 to 20o C, and isotemperature Hartmann`s solution immersion of the pleural cavity.

  • Objectives: Radix Ginseng has been used for thousands of years to treat a wide variety of diseases. Radix ginseng has also been used as a traditional medicine for boosting Qi energy and tonifying the spleen and lungs. Traditionally, its effect could be obtained orally. Nowadays, a new method, the injection of herbal medicine, is being used. This study was performed to investigate the single-dose intravenous toxicity of water-soluble ginseng pharmacopuncture (WSGP) in Sprague-Dawley (SD) rats. Methods: All experiments were carried out at Biotoxtech, an institute authorized to perform non-clinical studies under the regulation of Good Laboratory Practice (GLP). At the age of six weeks, 40 SD rats, 20 male rats and 20 female rats, were allocated into one of 4 groups according to the dosages they would receive. The WSGP was prepared in the Korean Pharmacopuncture Institute under the regulation of Korea-Good Manufacturing Practice (K-GMP). Dosages of WSGP were 0.1, 0.5 and 1.0 mL/animal for the experimental groups, and normal saline was administered to the control group. The rat's general conditions and body weights, the results of their hematological and biochemistry tests, and their necropsy and histopathological findings were investigated to identify the toxicological effect of WSGP injected intravenously. The effect was examined for 14 days after the WSGP injection. This study was performed under the approval of the Institutional Animal Ethics Committee of Biotoxtech. Results: No deaths were found in this single-dose toxicity test on the intravenous injection of WSGP, and no significant changes in the rat's general conditions and body weights, the results on their hematological and biochemistry test, and their necropsy findings were observed during the test. The local area of the injection site showed minial change. The lethal dose was assumed to be over 1.0 mL/animal in both sexes. Conclusion: These results indicate that WSGP is safe at dosages up to 1 mL/animal.

  • Wegener's granulomatosis(WG) is a necrotizing granulomatous small vessel vasculitis with a clinical predilection for involvement of the upper airways, lungs and kidneys. The disease usually manifests in adults between 25 and 50 years of age, but it can also rarely occur-in childhood with some features different from those of adults. WG may be easily overlooked in young patients by misinterpretion of the symptoms as caused by an infectious disease of the respiratory tract. Delayed diagnosis and treatment of the disease may cause more rapid progression of the glomerulonephritis to end stage renal disease. We report a boy who was diagnosed with WG with involvement of multiple organs at 13 years of age.

  • According to "Dongeuibogam(東醫寶鑑)", "the Shinnong Herb Bible(神農本草經)", "Chamdonggo(參同攷)", come to the conclusion about medical thought of "the Zhouyi Cantongxie(周易參同契)". Alchemy is a common field both on the eastern and western civilization, but a process of development is different. Ancient chinese alchemist made a study on external alchemy, but harmful consequences of external alchemy was consecutive, many scholars had turned their interest on internal alchemy which is related in human meridian biology and spirit. In the western alchemy has developed to make a study on analytic psychology and science of religion. Most importantly, the eastern and western alchemy have something in common what at the point of the perfection of self is similar, but the name is different, for example in the eastern alchemy we can be immortals and take a spiritual enlightenment with the elixir of life, in the western we can take a cure of souls as a christian. As for internal alchemy, "Cantongxie(參同契)" gives influence to the theories such as the theory of danjeon(lower part of the abdomen), evolution, aging, and life nurturing. Especially, the theory of danjeon shows such merit for studying since it is similar to triple energizers(三焦) and the theory of qi street(氣街) of oriental medicine. The study on "Cantongxie(參同契)" was achieved in Korea too, especially Chosun dynasty. "Candongkao (參同攷)" by Seo Myung-eung(徐命膺, 1716~1787) are representative. According to "Candongkao(參同攷)", Geon(乾), Gon(坤), Gam(坎), and Ri(離), the four trigrams for divination, each are affiliated with lungs, spleen, kidneys, and heart. Nowadays the study on alchemy correspond with modern trends, which are anti-aging and living without any disease. If processed mineral drugs is assured for stability, it can be used for incurable diseases such as cancer.

  • A case of aspergillosis in 39-day-old layer chickens having a history of gradual emaciation and subsequently death with nervous signs such as torticollis and lack of equilibrium was documented. Based on the results from serology and polymerase chain reaction (PCR) test, this flock was not affected with known viral or bacterial diseases. On postmortem examination of the affected birds, multiple white to yellow nodules measuring 1~5 mm in diameter were observed in the lungs, cerebrum, liver and kidney. Microscopically, these nodules were identified as granulomatous lesions characterized by mixed population of multinucleated giant cells and lymphocytes. By periodic acid-schiff staining and nucleotide sequencing analysis, Aspergillus flavus with characteristic septate and branched hyphae were identified in the granuloma of lung and cerebrum. This case was a chronic and multisystemic aspergillosis specialized to central nervous system caused by Aspergillus flavus infection in the layer flocks.

  • Sj$\ddot{o}$gren's syndrome (SS) is an autoimmune disorder primarily affecting the salivary and lacrimal glands. In addition, extra-glandular manifestations involving the lungs, liver, kidneys, pancreas, skin and central nervous system were reported in patients with SS. These extra-glandular manifestations are not rare in adult patient, but are very rare in pediatric SS. Renal manifestations are relatively common in adult SS, but are rarely reported in childhood SS. We experienced a girl with primary SS manifested with nephrogenic diabetes insipidus and renal tubular acidosis.

  • 1. Objectives The object of this thesis is to find the basis on why Jejo was assigned as a Taeumin medicine, and to understand Taeumin edema. 2. Methods ${\ulcorner}$Dongyisusebowon${\lrcorner}$ 'Shinchukbon', 'Gabobon', 'Chobonkwun', other related Sasang Constitutional Medicine(SCM) books, herbal medicine books such as ${\ulcorner}$Bonchokangmok${\lrcorner}$, and etc. were compared and researched. 3. Results & Conclusions (1) In Sasang Constitutional Medicine, edema is seen as a critical condition. The first cause of edema in Taeumin is fatigue, a condition where the flow of Qi and Fluid Qi is stagnated. Secondly, edema is caused as Taeeumin is mentally stressed(勞心焦思) and he/she is unable to accomplish his/her plans over many trials or as when they find pleasure in striving for greed. When Lungs which is Incline & Small Viscera(偏小之臟) in Taeumin decreases, it diminishes Real Count of Longevity(命脈實數) which leads to edema formation. (2) Perspective of Human Nature & Character(心性學) and Regimen(養生法) became included gradually in the treatment methods and prescription of edema in Taeumin as ${\ulcorner}$Dongyisusebowon${\lrcorner}$ was revised over time. The revisions also lead to more diversity in prescriptions. (3) Jejo didn't appear In ${\ulcorner}$Dongyisusebowon${\lrcorner}$ 'Chobonkwun' and 'Gabobon'. It was first presented in 'Shinchukbon' as a medicine to treat edema in Taeumin. (4) Jejo have effects of easing clumps. Also it has a strong radiating ability(發散力) which induces perspiration to treat diseases. Finally Jejo is used to remove Takki(濁氣) by utilizing powerful Exhale Gathering Qi contained in it.
