Hemangiopericytoma of the lung is a very rare malignant tumor despite it's high vasculities of the lung, because, this tumor arises from the pericytes enveloping capillaries. A pulmonary hemangiopericytoma was diagnosed in a 63-year-old female who had complained of cough, sputum, and intermittent chest pain for about 8 years. She was admitted to our hospital, because of progressive severe dyspnea on exertion and orthopnea for about 3 months. She was taken explothoracotomy and left pneumonectomy including evacuation of lots of blood clots due to ruptured large tumor and ineffective drainage with closed thoracic tube. She was discharged at post-operative 7 days under very good condition. She has been treated with radiotherapy&chemotherapy since then.

This study carried out to investigate the antimicrobial resistance and biochemical characteristics of Staphylococcus aureus (S. aureus) isolated from reproductive and respiratory tract in Thoroughbred horse. The specimens were collected from equine vaginal mucosa and upper respiratory tract from March to December 2006 using a culture swab in Korea. S. aureus suspected colonies on blood agar plates were selected and identified as standard biochemical tests and PCR (Applied Biosystems, USA). Antimicrobial resistance test of S. aureus isolates was performed with 30 antimicrobial agents (BBL, USA) by using the agar disk diffusion method. S. aureus isolates were isolated 58 (39.2%) strains of 148 samples: wound 64.7% (11/17), genital discharge 37.0% (37/100) and nasal discharge 32.2% (10/31). Almost isolates showed high resistance to spectinomycin, sulfonamides, erythromycin, tetracyelin, ciprofloxacin and penicillin. These results may provide the basic information to establish strategies for treatment and prevention of reproductive and respiratory disease in Thoroughbred horses in Korea.

This research aims to increase the extent of utilization of soybean curds coagulated with $Glucono-{\delta}-lactone$ (GDL) as a protein soarce by analyzing nutritive guality and preference to them. The curds were made from two kinds of soybean, domestic and imported. The results were as follows; 1. The yield of the domestic soybean curd was higher than that of the imported. 2. The total nitrogen and amino acid content of the GDL soybean curd were higher in the do- mestic while lipid and ash were higher in the imported one. 3. Rheological properties such as hardness, toughness, springiness and chewiness were higher in the domestic soybean curds than those of tile imported. 4. The 'L' values of the GDL soybean curds were higher in the domestic. However, there were no significant differences in the 'a' and 'b' values between the domestic and the imported soybeans. 5. According to the organoleptic the GDL soybean curds were not so favorable to our preferences .

A 75-year-old male patient without any significant medical and habitual risk factors for acute atherosclerosis obliterans except for hypertension was diagnosed with coronavirus disease 2019 with dyspnea, coughing, and mild fever. After a week of hospitalization, he complained of right foot pain and numbness. The symptoms were aggravated during the next week, resulting in a complete toe color change and loss of dorsalis artery pulse. Enhanced 3-dimensional computed tomography angiography revealed thrombus formation in the right common iliac artery and a loss of blood flow below the popliteal artery on both sides. The patient underwent percutaneous balloon angioplasty with stent insertion followed by medical therapy for anticoagulation. The clinical symptoms immediately were improved after the intervention, but the great toe necrosis was not recovered. Finally, amputation of the great toe was performed.

Persistent sciatic artery (PSA), a rare congenital vascular anomaly, increases susceptibility to aneurysms and accounts for 40-61% of the cases. Here, we describe a case of PSA in a 70-yearold man with a history of alcoholic liver cirrhosis. Bilateral complete PSAs were detected incidentally on computed tomography angiography during evaluation for spontaneous intramuscular bleeding in the thigh due to cirrhosis-related coagulopathy. Selective angiography of the left PSA revealed aneurysmal dilatation and thrombotic occlusion of the PSA, which was partially removed with aspiration thrombectomy. Intramuscular bleeding was succesfully managed with empirical embolization of the deep femoral artery.

This case underscores the rarity of bilateral subcapsular renal hematoma (SCH) as a complication of acute pyelonephritis, and this is the first reported case in South Korea. SCH can have various underlying causes, including cysts, bleeding tendencies, cancer, vascular diseases and, less commonly, infections. A patient with uncontrolled diabetes mellitus and alcohol dependency presented with weakness. Bilateral SCH from acute pyelonephritis was diagnosed and treated with antibiotics and renal replacement therapy. Despite improved renal function, 30-day bilateral percutaneous drainage was necessary due to a persistent fever and elevated infection markers, resulting in a bloody, pus-like discharge. This case report sheds light on the rare etiology of bilateral SCH as a result of acute pyelonephritis. It serves as a reminder of the critical importance of timely intervention, to prevent deteriorating outcomes.

Purpose : Pathologically, Kawasaki disease (KD) is associated with widespread vascular endothelial damage in the acute phase. The vasculitis induced endothelial injury leads to coagulation abnormalities. Abnormalities of endothelial function, platelet activation, and fibrinolysis are present during acute phase and long after the onset of KD. The aim of study is to evaluate the change of hemostatic markers in the clinical stages of KD and to assess the hemostatic markers to be a useful indicator of the development of coronary artery lesion (CAL). Methods : Seventy four KD patients diagnosed in Chungnam National University Hospital from November 2004 to June 2007. Eleven febrile control and eleven healthy children were selected for healthy control. All blood samples were collected before and after Intravenous gammaglobulin (IVGG), $2^{nd}$ week, and $4^{th}-8^{th}$ week of illness of KD. Results : Initial D-dimer level of Kawasaki disease showed meaningful difference compared to control group (P<0.05). D-dimer and fibrinogen degradation products (FDP) before IVGG increased compared with normal control group and decreased after IVGG administration. It is normalized until 2 weeks later, and continue to decreasing. D-dimer and FDP were significantly different according to the CAL before IVGG. Conclusion : The hemostatic markers may change to the clinical stage of KD, which may suggest the degree of endothelial injury. Increased some hemostatic markers may be the predictors for development of CAL.

Background: The aims of the present study were to assess and compare mid-term clinical outcomes including recurrences between endovenous laser therapy (EVLT) and stripping. Material and Method: Between January 2007 and February 2010, 318 limbs in 237 patients with saphenous truncal varicosities were treated by laser energy using a 980 nm diode or were treated with conventional stripping. At the initial visit and at 1, 2, 6, 12, 18, 24, and 36 months postoperatively, clinical examination and questioning for Venous Clinical Severity Score (VCSS) as well as duplex ultrasonography were done. In order to compare clinical outcomes between the two treatment groups, EVLT versus stripping, all data were processed and analyzed. Result: There were no significant differences between the two treatment groups in the extent of the reflux and the number of insufficient perforating veins. The in EVLT and the stripping group at 12 months were $90.3{\pm}4.5%$ and $93.9{\pm}4.2%$, respectively (p>0.05). Total recurrence rates were 4.4% in the EVLT group and 1.5% in the stripping group (p>0.05). In both groups, the VCSS scores were significantly reduced at week 1, 1 month, and 2 months after EVLT or stripping (p<0.001). Conclusion: Efficiency in eliminating truncal saphenous vein incompetence and reducing venous clinical severity were equal in the two treatment groups.

This study was conducted to evaluate the quality characteristics of mugwort-tofu prepared by purified salt (A1), sun-dried salt (A2), bamboo salt (A3), and deep ground water salt (A4) in addition to $CaCl_2$ as coagulants. Addition of various salts with $CaCl_2$ increased yield of the tofu resulting in high content of lipid, protein and mineral contents of mugwort-tofu. Sun-dried salt was most effective in yield of the tofu among tested salts. It was also most efficient in increasing protein, and lipid contents of the tofu. The amounts of Ca, K, Mg, and Na were highest in mugwort-tofu prepared with sun-dried salt, while they were lowest in the tofu with deep ground water salt. The texture analysis showed the tofu prepared with various salts generally increased the hardness and gumminess of the tofu significantly. The sensory evaluation of the tofu with various salts demonstrated that the saltiness, tastiness, chewiness, and overall acceptance were enhanced significantly. Among tested salts, bamboo salt showed the highest overall acceptance in mugwort-tofu, followed by deep ground water salt, purified salt, and sun-dried salt.
