The reports of sarcoidosis have increased in Korea since 1968. Osseous sarcoidosis is 3%-5% of sarcoidosis, but it is not reported upto date in Korea. So, we report a case of sarcoid dactylitis. A 47-year old woman who complained of painful swelling in her fingers was admitted in Korea University Guro Hospital. She had visited local clinics 3 years ago for chronic cough, multiple subcutaneous nodules and erythematous elevated regions on extensor sides of both extremities, and taken medicine under the diagnosis of pulmonary tuberculosis for 3 years. On admission her distal phalanges showed fusiform swelling, and multiple 1 cm-sized papules were found on the extensor area of extremities. The chest CT scan and the skin biopsy which had been performed in local clinics were reviewed to examine whether it was tuberculosis or not, but the results were compatible to sarcoidosis. So, under the impression of sarcoidosis chest CT and biopsy of hand lesions were performed again. And the patient was prescribed prednisolone 30 mg, and Hydroxychloroquine 400 mg per day, and then showed improvement of pain and skin lesions.

Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive neoplastic proliferation of B and T lymphocytes commonly involving the lungs. Epstein-Barr virus is commonly detected in lesional cells. We report a case of a 54-year-old female with underlying monoclonal gammopathy of unknown significance who presented with a 4 week history of dyspnea and cough. Computed tomography scan of the chest showed multiple lung nodules as well as endobronchial narrowing causing atelectasis at the left upper lobe. Bronchoscopic findings revealed obstruction at the lingula segment due to endobronchial mass as a rare presentation. Bronchoscopic biopsy was diagnosed with LYG grade 1. After treatment, the endobronchial mass and lung lesions were completely resolved. However, the patient eventually evolved to malignant lymphoma after 1 year.

Objectives : Ojeok-san, a traditional herbal formula, has been used for the treatment of cold illness and its related symptoms such as headache, nausea and indigestion. This study was performed to compare effects of water (OJSW) and 70% ethanol extracts (OJSE) of Ojeok-san on inflammation and its related diseases atopy, asthma and obesity in vitro. Methods : We performed HPLC to investigate contents of index components of OJSW and OJSE. We investigated the effects of OJSW and OJSE with an in vitro model, using 5 cell lines, specifically RAW 264. 7, HaCaT, MC/9, BEAS-2B and 3T3-L1. Results : HPLC analysis displayed that the contents of index components were higher in OJSE than OJSW. In lipopolysaccharide (LPS)-treated RAW 264.7 macrophages, OJSE significantly inhibited productions of interleukin (IL)-6, nitrite and prostaglandin $E_2$ ($PEG_2$). In TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT keratinocytes, OJSE significantly lowered levels of macrophage-derived chemokine (MDC) as well as regulated and normal T cell expressed and secreted (RANTES). OJSE also had a protective effect on inflammatory response by decreasing RANTES secretion in TNF-${\alpha}$-stimulated BEAS-2B cells. Conclusions : We conclude that OJSE could be more appropriate to enhance the biological activities against inflammation and its related diseases, and could be applied as a bioactive material for developing the potent anti-inflammatory agents.

Nonspecific interstitial pneumonia (NSIP) was first described as a new category of idiopathic interstitial pneumonia in 1994. This is a disease with a more insidious onset and has a chronic course. The histological findings are unusual for other idiopathic interstitial pneumonia cases (usual interstitial pneumonia, diffuse interstitial pneumonia, and acute interstitial pneumonia). In contrast to NSIP, acute interstitial pneumonia (AIP) has an acute onset and a fulminant course with the rapid development of respiratory failure. A pathological examination demonstrated characteristic diffuse interstitial fibrosis, hyaline membranes, thrombi, and architectural derangement. Here we report a 48-year-old woman who was diagnosed pathologically NSIP, but with a rapid progressive course similar to AIP.

We experienced a rare case of trachea diverticula combined with the sequela of tuberculosis and a fungus ball. The patient had complained of coughing and hemoptysis for a long time after experiencing tuberculosis. He was admitted due to hemoptysis and the aggravation of coughing. The CT scan showed a variable sized trachea diverticula combined with tuberculosis sequela and a fungus ball in the right lung fields. The diagnosis was made by bronchoscopy and a CT scan. After bronchial artery embolization and conservative treatment, the patient's symptoms improved and the patient was discharged.

Cryptococcosis is an invasive fungal infection, which is more common in immunocompromised patients. However, pulmonary cryptococcosis can occur in immunocompetent patients and should be considered on a differential diagnosis for nodular or mass-like lesions in chest radiograph. Recently, we experienced a patient with pulmonary cryptococcosis, successfully treated with oral fluconazole therapy. A 74-year-old female patient was referred for an evaluation of abnormal images, a large consolidative mass with multiple nodular consolidations and small nodules that mimics primary lung cancer with multiple lung to lung metastases. Computed tomography-guided lung biopsy confirmed the diagnosis of pulmonary cryptococcosis. The follow-up image taken after 4 months with oral fluconazole treatment showed marked improvement.

Asparagus oligoclonos is one of the endemic halophytes used folk medicine in Korea. We isolated the main compound rutin from methanol extracts of A. oligoclonos based on nuclear magnetic resonance and TOF ESI-MS data. We have investigated the quantitative analysis method of main compound using HPLC and the results exhibit that rutin content of A.oligoclonos were 1.816%. To explore anti-oxidant from A. oligoclonos ethanol extracts (AOE), we investigated the antioxidant effects of AOE on $H_2O_2$-induced oxidative stress in RAW 264.7 cell. AOE were reduced $H_2O_2$-induced oxidative stress via enhancement of cell viability, and AOE significantly decreased ROS production depending on concentration. Next, to screen for anti-inflammatory activity of AOE, we investigated the inhibitory effects of AOE in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. AOE had no effect on cell viability at a concentration of $500{\mu}g/mL$. Nitric oxide (NO) production inhibited in a dose-dependent manner. These results suggest that AOE may be a useful antioxidant and anti-inflammatory agent.
