Involvement of the vena cava by direct vascular extension of renal cell carcinoma occurs in approximately 5% of patients undergoing nephrectomy for this neoplasm. While successful, removal of caval neoplastic thrombi has been reported occasionally, it has been general impression that renal cell carcinoma extending into the vena cava carried an extremely poor prognosis. A 45 years-old male patient was admitted with painless gross hematuria and palpable mass on fight upper quadrant. Surgical exploration was done through 10th thoracoabdominal incision. A right nephrectomy and retroperitoneal lymph node dissection were done for renal cell carcinoma. It was evident on palpation that the tumor was in the It was evident on palpation that the tumor was in the inferior vena cava Partial resection of the inferior vena cava and removal of intra vena cava thrombus were performed. This patient has led a normal life for 18 months following surgery without clinical evidence of tumor. And so, we were presented with review of the literature.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

We report a case of primary cutaneous mucinous adenocarcinotna in a 64-year-old female. The tumor was about 2cm in size, forminga round dome-shaped alopecic scalp mass which had gradually increased in size over about 5 years, Histalogic examination revealed that the tumor was divided into numerous compartments by strands of fibrous tissue. In each compartment, abundant amounts of pale-staining mucin surrounded nests or cords of moderately anaplastic epithelial cells. We couldn't find any evidence of internal neoplasms as a source of metastasis. We resected the tumor with approximately a 1 cm margin and then performed a split thickness skin graft.

6.Read-through Mutation in the Coat Protein ORF Suppresses Turnip Yellow Mosaic Virus Subgenomic RNA Accumulation.
Journal of Bacteriology and Virology 2013;43(1):54-63
We have previously observed that a sequence in coat protein (CP) ORF of Turnip yellow mosaic virus (TYMV) is required for efficient replication of the virus. The sequence was predicted to take a stem-loop structure, thus termed SL2. While examining various SL2 mutants, we observed that all the modifications resulting in extension of translation beyond the CP ORF significantly suppressed subgenomic RNA accumulation. The genomic RNA level, in contrast, was not affected. Introduction of an in-frame stop codon in the CP ORF of these constructs restored the level of subgenomic RNA. Overall, the results suggest that the read-through makes the subgenomic RNA unstable.

BACKGROUND: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. METHODS: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index (MEPI). RESULTS: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final follow-up (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. CONCLUSIONS: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

Bezoyl peroxide, a powerful oxidizing agent, has been uaed topically in the treatment of acne vulgaris as a cream or lotion and has been shown to he effective for this codition. In 1972 Fulton emphaaized the importance of the vehicles used to obtain. maximum potential of benzoyl peroxide and for this, the gel formulation has been examined in many clinical trials. The present study was undertaken to evaluate the therapeutic effect of Fanoxyl 2.5, a 2.5% . benzayl peraxide gel, in patients with acne vulgaris. A total of 31 patients entered this study at the Departrnent of Dermatology, Jeoul National University Hospital rluring 3 rnanths period, from Decemher, 1978 through February, 1979, All patienta were instructed to apply Fanoxyl 2.5' on their affected areas once or twice a day and the nurnber of lesions on two or three t fixed areas were counted before and onee weekly after initation of the treatment. The reaults observed in the 3I patients were as follaws; 1. The percentage decrease in total nurnber of lesions in 4 weeks after treatment was 56.9%. 2. The authors could follow up for 6 weeks in 6 cases. In 6 case, the mean percentage in total number of lesions in 6 weeks after treatment was 81.7%. 3. Clesed and open eomedones were gradually eliminated; and their numbers were decreased in 4 weeks after treatment by 46.5% and 56.8% respeetiveIy. The papules were rapidly eliminated and their numbers were decreased in 4 weeka, after treatment by 79.8%. 4. Although most patients felt a mild burning sensation and tightness at the begining of the treatment, only a minority of the patients complained of discomfort due to pain(l case), erytherna(l case), tightness(2 cases),burning sensation (1 case), scaling(1 case). But all were tolerable without taking any specific measures or discontinuance of application. In one case, contact dermatitis developed after 4 weeks treatment. The authors concluded through this experiment that Panoxyl 2.5' (2.5% benzoyl peroxide gel) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

This study was performed to investigate the effect of endotoxin to the CCl4-induced liver injury. Twelve Sprague-Dawley rats were intraperitoneally injected 1.6 g/kg CCl4 as control group. Another 24 rats were orally administrated 300 mg/kg of neomycin at 16 and 3 hours prior to CCl4 injection as experimental group. Twelve among them were intraperitoneally infected 1.0 mg/kg of endotoxin(E-Coli, 0111:B4, No L-2630, lipopolysaccharide, Sigma, USA) and CCl4 simultaneously for offsetting neomycin effect. The rats were sacrificed at 1, 4, 10, and 24 hours after CCl4 injection. The liver tissues from all experimental groups were observed by light and electron microscopy. The results obtained were summarized as follows: In the CCl4 only group, the hepatocytes revealed sweling of ER and mitochondria with many lipid droplet in the cytoplasm. Focal cellular necrosis was seen at the later phase. The Kupffer cells were activated and showed many cytoplasmic processes, secondary lysosomes, and vaculoles. The endothelial cells were edematous. Several neutrophils, platelets, and microthrombi were scattered in the sinusoid. In the neomycin-CCl4-endotoxin administrated group, both hepatocytic destruction and intrasinusoidal microthrombi formation were more pronounced. In the neomycin pretreated group, the hepatocytes revealed mild cellular destruction without necrosis. There is no intrasinusoidal microthrombi. According to these results, it would be concluded that the small dosage of gastrointestinal tract-derived endotoxin affects to the liver injury caused by CCl4. The synergistic effects of CCl4 and gastrointestinal tract-derived endotoxin which can not be detoxified by damaged Kupffer cells, may be more important in the pathogenesis of CCl4-induced liver injury.
