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.

It is been known that the deltoid ligament of the ankle joint plays an important role in the stabiliy of the ankle joint. In cases of deltoid ligament rupture, associated with lateral malleolar fractures, cannot be maintained the integrity of the mortise and the stability of the talus. Controversy remains about the treatment of deltoid ligament injuries. Many authors advocate an operative repair for deltoid ligament ruptures for optimal reduction of lateral malleolar fracture. However, according to recent cadaveric studies and many satisfactory results of clinical studies, excellent results have been reported regarding the ankle joint stability by anatomical reduction of the lateral structure, but only without surgical repair of the medial structure. Fourteen patients with lateral malleolar fractures with associated deltoid ligament injuries treated at Sun General Hospital between January 1990 and June 1995. There were examined clinically and radiologically. We concluded that deltoid ligament repairs should be considered unnecessary as long as fibular fracture are stabilized anatomically with normal medial joint space. However, in cases with higher fracture levels of lateral malleolus, associated with syndesmotic injury, we recommend syndesmotic screw fixation or deltoid ligament repair.

PURPOSE: In most cases, myelodysplastic syndrome(MDS) transforms into a more aggressive state or acute myelogenous leukemia; it's prognosis is very poor. It is believed that hematopoietic stem cell transplantation(HSCT) is the only curative treatment of MDS, but available data in children are very sparse. In this report, the short term outcome of HSCT in childhood MDS was analyzed. METHODS: Ten children with MDS(CMMoL 5, RAEB 3, RAEBt 2) underwent HSCT(HLA- matched sibling transplantation 4, HLA-matched unrelated transplantation 4, cord blood transplantation 1, HLA-mismatched familial transplantation 1) between November 1995 and January 2001 at St. Mary's Hospital. Median follow-up duration was 11 months. RESULTS: Engraftment was successful in all cases and 8 patients are alive without disease. Three cases of VOD were observed and improved without complication. Four cases of grade II and 1 case of grade III acute GVHD were observed and well controlled with treatment. Three patients relapsed after transplantation. One patient is alive without disease after cytoreduction with allogenic stem cell rescue and 2 patients died of relapse. CONCLUSION: HSCT is a curative strategy of MDS and the survival rate is relatively higher than that of adults. But there is an obvious need for more studies because of the small number of patients and the short duration of the follow-up.

PURPOSE: The Roux en Y method has rarely been performed due to longer operation time and high risk of complication, despite several merits including prevention of bile reflux. We conducted a retrospective review of the result of Roux en Y reconstruction using two circular staplers after subtotal gastrectomy. MATERIALS AND METHODS: From December 2008 to May 2009, a total of 26 patients underwent Roux en Y reconstruction using two circular staplers after subtotal gastrectomy, and seventy-two patients underwent Billroth-I reconstruction. Roux en Y anastomosis was performed using two circular staplers without hand sewing anastomosis. We compared clinicopathologic features and surgical outcomes between the two groups. All patients underwent gastrofiberscopy between six and twelve months after surgery to compare the bile reflux. RESULTS: No significant differences in clinicopathologic findings were observed between the two groups, except for the rate of minimal invasive surgery (P=0.004) and cancer stage (P=0.002). No differences in the rate of morbidity (P=0.353) and admission duration (P=0.391) were observed between the two groups. Gastrofiberscopic findings showed a significant reduction of bile reflux in the remnant stomach in the Roux en Y group (P=0.019). CONCLUSIONS: When compared with Billroth-I reconstruction, Roux en Y reconstruction using the double stapler technique was found to reduce bile reflux in the remnant stomach without increasing postoperative morbidity. Based on these results, we planned to begin a randomized controlled clinical trial for comparison of Roux en Y reconstruction using this method with Billroth-I anastomosis.

BACKGROUND: The diagnosis of malaria has been usually made using microscopic examination of Wright stained thin blood films in Korean army. This method is labor-intensive, time consuming and requires the microscopic expertise. Therefore, the alternative techniques, rapid diagnostic test, have been sought for use in Korean army. We performed a comparison of the OptiMAL test with GENEDIA Malaria (P. vivax) Ab Rapid I, II to assess its sensitivity and specificity of Plasmodium vivax malaria. METHODS: Blood specimen were collected from 51 patients who were presented and initially diagnosed for P. vivax by the microscopy of blood smears and from 30 control patients without malaria infection at the Capital Armed Forces General Hospital (CAFGH) between October 2000 and February 2001. Among the 51 patients, we also collected 24 samples from 24 patients at 2 or 3 days after therapy. The OptiMAL test and GENEDIA Malaria (P. vivax) Ab Rapid I, II were performed according to the manufacturer's instructions on all samples respectively. RESULTS: Compared with the blood film, sensitivities and specificities of the OptiMAL test, GENEDIA Malaria (P. vivax) Ab Rapid I and GENEDIA Malaria (P. vivax) Ab Rapid II were 94.1~100% (29/29), 80.4~83.3%, 96.1~96.7% respectively. One case was interpreted as 'undetermined' by OptiMAL test. In 24 patients during therapy, the sensitivities of the OptiMAL test, GENEDIA Malaria (P. vivax) Ab Rapid I and GENEDIA Malaria (P. vivax) Ab Rapid II on 8 specimens with mean 120/microliter parasitemia and 16 specimens with negative parasitemia were 75~43.8%, 87.5~81.3%, 100~100% respectively. CONCLUSION: Our data demonstrated that the sensitivity and specificity of the GENEDIA Malaria (P. vivax) Ab Rapid I were not satisfactory, but the sensitivity and specificity of the OptiMAL test and GENEDIA Malaria (P. vivax) Ab Rapid II were relatively high and useful diagnostic tests for diagnosis of P. vivax in areas like the militaries where laboratory facilities are poor or non-existent.

Ehlers-Danlos syndrome (EDS) is a rare inherited connective disease. Among several subgroups, type IV EDS is frequently associated with spontaneous catastrophic bleeding from a vascular fragility. We report on a case of carotid-cavernous fistula (CCF) in a patient with type IV EDS. A 46-year-old female presented with an ophthalmoplegia and chemosis in the right eye. Subsequently, seizure and cerebral infarction with micro-bleeds occurred. CCF was completely occluded with transvenous coil embolization without complications. Thereafter, the patient was completely recovered. Transvenous coil embolization can be a good treatment of choice for spontaneous CCF with type IV EDS. However, every caution should be kept during invasive procedure.

Myasthenia gravis has been associated with a variety of autoimmune diseases, but the association of myasthenia gravis with idiopathic thrombocytopenic purpura has been rarely reported. A previously healthy 33-year-old female presented with a 10-month history of easy fatigability, motor weakness, diplopia and menorrhage. Clinical and labora-tory findings supported the diagnosis of myasthenia gravis and idiopathic thrombocytopenic purpura. After a thymecto-my, there were surprising improvements not only in muscle strength, but also of thrombocytopenia. Though this associ ?ation may be incidental, the patient's progress suggests that idiopathic thrombocytopenic purpura may be closely relat-ed to myasthenia gravis immunologically because both diseases developed simultaneously and showed good therapeu-tic responses after a thymectomy.
