1.Immunologic reactivity of a lipopolysaccharide-protein complex of type A Pasteurella multocida in mice.
Journal of Veterinary Science 2000;1(2):87-95
The immunologic reactivity of a lipopolysaccharide (LPS)-protein complex isolated from a potassium thiocyanate extract of a Pasteurella multocida (capsular type A and somatic type 3) strain was evaluated in mice. The LPS-protein complex provided 100% protection in mice against a challenge with the homologous strain. However, when the complex was fractionated into LPS and protein moieties by phenol-water treatment, both components lacked immunogenicity. The complex and extracted components were mitogenic for mouse B lymphocytes with the protein moiety the most active. Although immune serum against the LPS-protein complex protected mice against challenge thereby indicating a role for humoral immunity, the LPS-protein complex of P. multocida was also found to induce cell-mediated immunity. This cell-mediated immunity was demonstrated in mice immunized with the complex by: (1). mitogenic responses of T lymphocytes, (2). induction of delayed type hypersensitivity reaction in the hind footpads, and (3). enhanced resistance to challenge infection with Salmonella enteritidis.

Primary pericardial tumors are rare than those originating within the myocardium or endocardium and, moreover, primary benign pericardial tumors are much rare in occurrence. Fine(1986) was able to collect only 43 cases of lipoma. Most cases are diagnosed only at autopsy. One fourth of the cardiac lipoma arise subepicardially, where they suggest the presence of pericardial effusion with compression or displacement of the heart. A case of primary intrapericardial lipoma simulating pericardial effusion is presented. This tumor originated in left anterior aspect of pericardium. The tumor was measured 30x30x5cm in size and 2,200mg in weight. Total excision of the mass was accomplished by posterior lateral thoracotomy incision, resulting in complete cure. This is the first case of primary benign lipoma of the pericardium in literatures in our knowledge.

5.A Case of Leukemia Cutis in Myelodysplastic Syndrome Evolving into An Atypical Chronic Myeloid Leukemia.

We report a patient who had been initially diagnosed as a myelodysplastic syndrome in 1998 presenting purpuric patches on the left arm that started to develop about a year prior. The purpuric lesions were diagnosed as leukemia cutis by skin biopsy. Her subsequent bone marrow biopsy showed progression into an atypical chronic myeloid leukemia with increased numbers of leukocytes in the peripheral blood. Leukemia cutis typically is regarded as a sign of progression of disease or a manifestation of recurrent disease in treated patients with an established diagnosis of leukemia. We suggest that the skin lesion in this patient could have been a sign of con-version into atypical chronic myeloid leukemia.

Bicoronal approach is adopted as an universal method for reduction and internal fixation of the fractured zygomatic arch in the treatment of complex zygomatic fracture. However bicoronal approach leaves many disadvantages, such as long incision, alopecia, prolonged edema, and paresthesia. Nowadays endoscopically assisted minimal invasive technique has been widespread not only for the aesthetic surgery, but also for the reconstructive surgical fields because of the benefits. We have been recently trying to apply endoscopic surgery to facial bone fracture surgery. Endoscopically assisted minimal invasive technique has been applied to 14 patients who admitted to Chosun university hospital from March 1996 to July 1997. We used 4 mm, 30' endoscope and two 1.5-2 cm temple incisions and a subciliary incision for approaching to the zygomatic arch. Protected drill bit and driver had access to fractured zygomatic arch though tiny(5 mm) stab incision over the zygomatic arch. We have been able to successfully reduce and make fixation of the fracture of zygomatic arch by using endoscopically assisted minimal invasive technique. Follow up for 3 months revealed good maintenance of the reduction. We think that application of the endoscopic technology to midfacial bone fracture will result in significant reduction in morbidity and improve postoperative results.

9.Preliminary Results of Neoadjuvant M-VAC(Methotrexate, Vinblastine, Adriamycin, Cisplatin) Chemotherapy for Bladder Carcinoma.
Korean Journal of Urology 1990;31(1):59-64
The trend in chemotherapy of bladder carcinoma has evolved from the single agent to the combination chemotherapy. In 1985 Sternberg et al. reported 71 per cent of significant tumor regression and 50 per cent of complete clinical remission with M-VAC(methotrexate, vinblastine, adriamycin and cisplatin) combination chemotherapy of treatment for advanced urothelial transitional cell carcinomas. Therefore, the effects of neoadjuvant systemic M-VAC chemotherapy in 23 patients with bladder carcinoma at the Department of Urology, Chonnam University Hospital from January 1987 to June 1989 were evaluated. The following results were obtained. 1. The average number of cycle were 2.1 and the cycle length varied from 28 days to 52 days (average: 32.8 days). 2. Clinical complete and partial remission rate were obtained in 11 patients( 47.8 per cent), while 6 patients( 26.1 per cent) had a minor response, 4 patients( 17.4 per cent) stabilization and 2 patients (8.7 per cent) progression. 3. After chemotherapy, 13 patients underwent operation (radical cystectomy 8, partial cystectomy and lymph node dissection 4, transurethral resection of bladder tumor 1) and there were no lymphatic metastasis except only one advanced case. 4. Toxicity included leukopenia in 21 patients and all patients had experienced alopecia, nausea, vomiting and general weakness. It was suggested that neoadjuvant M-VAC chemotherapy may be effective as treatment for patients with invasive bladder carcinoma and we need to define further and extend the potential roles of neoadjuvant chemotherapy for carcinoma.

OBJECTIVES: To investigate the relationship of serum uric acid to cardiovascular risk factors in Korean male workers. METHODS: We screened 522 male workers at an electrical manufacturing company by a periodic health examination and a questionnaire survey in 2000. We collected data relating to age, smoking status, alcohol drinking status, body mass index (BMI), blood pressure, serum lipid, fasting blood glucose and serum uric acid. The data were analyzed using a variety of methods, including ANOVA, Pearson's correlation, and multivariate regression analyses, to examine the association between uric acid and cardiovascular risk factors with a cross-sectional study design. RESULTS: The concentration of serum uric acid showed positive associations with BMI, total cholesterol, triglyceride, and LDL-cholesterol; it was also significantly correlated to systolic and diastolic blood pressures. Life-style characteristics, such as smoking and alcohol drinking showed no significant association. From the multivariate regression analyses, BMI, total cholesterol and fasting blood glucose levels were found to be independent positive predictors of uric acid; while age, blood pressure and smoking status give no independent contribution explaining the variability of serum uric acid levels. Conclusions : This study demonstrates that serum uric acid level have a significant association with cardiovascular risk factors, such as BMI, total cholesterol and blood glucose in some Korean male workers.
