Interleukin-6 (IL-6) is introduced as a marker of disease. At present, a variety of method may be used to quantify expression of this protein. Antigen capture-ELISA is a sensitive and accurate quantification method previously used with ovine, rat, and human IL-6 proteins. However, it has never been reported to quantify porcine IL-6 protein using capture ELISA. In this study, we generated and characterized a set of IgY and mono-specific polyclonal antibodies to recombinant porcine IL-6 (rpIL-6), and combining these with a sensitive and specific capture-ELISA for a diagnostic purpose. cDNA encoding the mature protein coding region of porcine IL-6 was cloned and expressed with pQE-30UA expression vector. rpIL-6 was then expressed and purified by using Ni-NTA resin. Protein mass of 24 kDa was found with SDS-PAGE and the identity of the protein was confirmed by Western-blot. Production of polyclonal antibodies against rpIL-6 was performed using the purified rpIL-6 in mice and hens. An antigen capture-ELISA was developed with the antibodies after their extraction. To compare the IL-6 level in the different sanitary state of farms, pig sera were randomly collected and concentration of IL-6 in the sera was measured with the antigen capture-ELISA. The capture-ELISA with the optimal concentration of antibodies, in this study, was able to detect about 10 ng/ml of rpIL-6. IL-6 levels determined with the capture-ELISA in pig sera showed positive correlation with the sanitary states of the farms. These results suggested that the developed antigen capture-ELISA could be a good tool for the screening of microbial infection in pig farms.

Spontaneous cervical epidural hematoma (SCEH) is a rare condition that causes paraparesis or
quadriparesis. As spontaneous resolution is seldom expected, it usually requires surgical treatment
for relieve symptoms. Even if spontaneous resolution occurs, relief from symptoms usually requires
several hours to days. In contrast, hemiparesis is the most common symptom of a transient ischemic
attack (TIA), and usually resolves over minutes to hours. We report here two patients with SCEH
who presented with hemiparesis with severe neck pain. Both patients were taking antiplatelet drugs.
Their neurological symptoms recovered spontaneously over a very short time. They were initially
misdiagnosed as TIA. These cases show that patients with transient hemiparesis may have SCEH if
there is severe neck pain and no cranial nerve involvement.

Pancoast syndrome (PS) is characterized by a malignant neoplasm of the superior sulcus of the lung with destructive lesions of the thoracic inlet and involvement of the brachial plexus and cervical sympathetic nerves. The most common initial symptom of PS is shoulder pain; however, cough, dyspnea, and hemoptysis, signs often associated with lung cancer, are not as common. Investigation of PS can be difficult even with plain radiographs of the chest because it is surrounded by osseous structures such as the ribs, vertebral bodies, and manubrium. Due to these characteristics, orthopedic surgeons tend to make a misdiagnosis resulting in delay of appropriate treatment. Here we report on a patient who was supposed to undergo rotator cuff repair for his shoulder pain and weakness, and was eventually diagnosed with PS.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

In complication of infective endocaditis splenomegaly and splenic infarction are not uncommon but splenic rupture is very rare. We report a case of splenic rupture complicated by infective endocarditis in 1 71-yr-old man who had been suffered from rheumatic heart disease (aortic regurgitation and stenosis and mitral regurgitation). The patient was admitted to mild fever and generalized weakness for 20 days. Diagnosis of infective endocarditis due to Staphylococcus epidermidis was made by clinical manifestaions and blood culture study.On 34th day of admissionthe patient suddenly displayed the symptoms and signs of massive intraperitoneal hemorrhage. Splenic rupture was revealed by paracentesis and radiologic studies. Rupture of spleen is an uncommon and usually fatal complication of infective endocarditis. Therefore early diagnosis and prompt treatment must be performed.

Paraneoplastic pemphigus is a distinct and rare autoimmune disease characterized by extensive and painful mucosal ulcerations and polymorphic desquamated skin lesions in the setting of an underlying neoplasm, typically of lymphoreticular origin. Thus difficulties in the management of anesthesia can be expected. A 66-years-old man was scheduled for removal of intraabdominal sarcoma associated with paraneoplastic pemphigus. Physical examination showed multiple erythematous bullae, crusts, plaques and target-like lesions on the whole body and desquamated erythematous skin lesions on the back and extremities. In the operating room, his right femoral artery was cannulated with a 20 G, 12.7 cm CVP catheter and left femoral and subclavian veins with 14 G, 20 cm CVP catheters, respectively. After application of 4 % lidocaine spray, his oropharynx and supraglottic area were evaluated under direct laryngoscopy and revealed multiple ulcerations on oral mucosa, but no distinct lesion on supraglottic area. Anesthesia was induced by rapid-sequence method with fentanyl, thiopental sodium and succinylcholine followed by endotracheal intubation. The endotracheal tube was held by a roll gauze around the neck and its cuff was minimally inflated to avoid overpressure against his tracheal wall. After the end of surgery, his oral cavity was suctioned with no remarkable bleeding, and tracheal wall including cuff-contacted area was evaluated under fiberoptic bronchoscopy, revealed intact wall without any bulla or ulceration. The patient was transferred to intensive care unit for proper postoperative management after extubation of endotracheal tube.

Gold preparation had been used frequently in the past in the treatment of rheumatoid arthritis, tuberculosis and lupus erythematosua, etc. It is still used. when other more potent remedies, such as steroid, failed. We report a case of drug eruption following the use of gold preparation. A 38 year-old female was referred to our department from orthopedic surgery because of generalized, multiple, pin head sized, violaceous and flat topped papules of 1 x 2 mm in size and mucosal erosions and ulcers following gold therapy for rheumatoid arthritis. She had received 5 intramuscular injections of gold preparation (Myochrysine'), 220mg in total amounts. Our clinical impression was lichen planus like drug eruption, but histopathological picture disclosed nonapecific dermatitis. The eruption had disappeared gradually following oral administration of antihistaminics and prednisolone and daily starch tub baths.

Double primary cancer is defined as the case of primary malignant tumors in one person, which must be arisen in different sites and have a different histologic appearances in each other. The number of reported cases of multiple primary malignant tumors has increased in recent years, because of more developed diagnostic procedure and long survival of cancer patients, We have experienced 4 cases of double primary malignant tumors which were stomach cancer with colon, bronchus and esophagus cancer, and report these cases with review of literatures.
