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.

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.

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.

Granulosa cell tumors are uncommon neoplasm of ovary that are characterized by their long natural history and for their tendency to recur years after an aparrent clinical cure. Endometrial cancer occurs in association with these tumor in at least 5% of cases and 25%-50% are associated with endometrial hyperplasia. In this study, we present a case of granulosa cell tumor of right ovary with endometrial cancer after left oophrectomy.

BACKGROUND: The purpose of this study was to evaluate the postoperative magnetic resonance imaging (MRI) results of minimal-tying (one medial-row tie among 4 medial-row sutures) on the medial-row in double-row suture-bridge configuration (2x2 anchor with 4x4 suture stands). METHODS: From 2011 March to 2012 July, 79 patients underwent arthroscopic rotator cuff repair using 2x2 anchor double-row configuration. The mean age was 61.3 years (range, 31-81 years). Two double-loaded suture anchors were used for medial-row. Four medialrow stitches were made with only one medial-row knot-tying (the most anterior suture). Lateral-row was secured using the conventional suture-bridge anchor technique; all 4 strands were used for each anchor. Repair integrity was evaluated with MRI at mean 6.2 months postoperatively. Retear and the pattern of retear, change of fatty infiltration, and muscle atrophy of supraspinatus were evaluated using pre- and postoperative MRI. RESULTS: Repaired tendon integrity was 38 for type I, 30 for type II, 6 for type III, 4 for type IV, and 1 for type V, according to Sugaya classification. Considering type IV/V as retear, the rate was 6.3% (5 out of 79 patients). Medial cuff failure was observed in 4 patients. Fatty atrophy of supraspinatus was significantly improved postoperatively according to Goutallier grading (p=0.01). The level of muscle atrophy of supraspinatus was not changed significantly after surgery. CONCLUSIONS: Minimal tying technique with suture configuration of four-by-four strand double-row suture-bridge yielded a lower retear rate (6.3%) in medium to large rotator cuff tears.

We have examined the regenerative capabilities of the human scalp hair follicle after grafting the lower half of the follicle. Twenty-eight of 32 intact whole-hair follicles isolated from the human scalp regenerated hairs when grafted onto the forehead of the same person. Seven of the 15 lower-half follicles regenerated complete hair follicles 8 months after grafting showed that the lower-half follicle implant reconstituted the complete hair follicle. The sebaceous gland was not regenerated, but there was an outgrowth in the sebaceous gland regPark ion. Some grafts formed epithelial cysts. Two years after grafting, the histological examination of the regenerated follicle from the lower-half implant showed that the sebaceous gland was completely regenerated. While an intact follicle shows prominent naked shaft outgPark Park Parkrowth, the sheath grows concomitantly with the shaft in lower-half follicles in culture. If grafted lower-half follicles were located too deep, the regrown sheath could not reach the epidermal layer. In this situation, the formation of an epidermal cyst was likely.

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.
