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.

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.

Tumor-draining lymph node (TDLN) lymphocytes contain immunologically sensitized to tumor but functionally deficient T cells. The 30 kDa protein antigen, a major secreted protein antigen of Mycobacterium tuberculosis, exhibits strong T cell stimulatory effect. In this study, it examined that the feasibility of using M tuberculosis 30 kDa antigen to stimulate tumor-draining lymph node cells for the generation of specific immune effector cells. Freshly isolated TDLN lymphocytes could directly respond to the 30 kDa antigen alone and their proliferative responses were markedly augmented by stimulation with rIL-2. TDLN cells were stimulated with the 30 kDa antigen for various time intervals and examined for the induction of IFN-r and IL-4 mRNA using RT-PCR. The expression of IFN-r mRNA was greatly augmented after 1 wk, whereas IL-4 mRNA is markedly decreased after 1 wk. Cytotoxic T cell activities induced by the 30 kDa antigen was also evaluated. TDLN cells stimulated with the 30 kDa antigen alone were able to generate remarkable cytotoxic response to K562 or Daudi cell lines after 6 days of culture. And their cytotoxic effects were highly augmented by stirnulation with rIL-2. These results suggest that the 30 kDa antigen of M. tuberculosis may selectively activate Thl cells of TDLN lymhocytes and induce the cytotoxic T cell activities. In conclusion, the 30 kDa antigen can be used as a biologic response modifier in tumor immunology.

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.

8.Characterization of a Replication Element in the Coat Protein ORF of Turnip Yellow Mosaic Virus.
Journal of Bacteriology and Virology 2012;42(1):49-55
Turnip yellow mosaic virus (TYMV) is a non-enveloped icosahedral virus that has a single 6.3 kb positive-strand RNA as a genome. Previously, it was observed that the recombinant construct TY-eGFP2, where an eGFP gene was inserted at the position downstream of the coat protein (CP) ORF of TYMV genome, barely replicated. The inhibition of replication was relieved by insertion of an additional copy of the 3' quarter of the CP ORF after the foreign sequence. In this study, we have examined if the 3' quarter of the CP ORF contains any replication elements. M-fold analysis predicted three stem-loop structures in this region. Analysis of the TY-eGFP2 constructs containing one or two of these stem-loop structures indicates that the secondary structure predicted in the region between nt-6139 and nt-6181, termed SL2, is essential for TYMV replication. The critical role of SL2 was confirmed by the observation that deletion of the 3' quarter of the CP ORF from the wild-type TYMV genome nearly abolished replication and that insertion of SL2 into the deletion mutant restored the replication. Mutations disrupting the stem of SL2 greatly reduced viral RNA replication, indicating that the secondary structure is essential for the enhancing activity.

9.A Sequence in Coat Protein Open Reading Frame Is Required for Turnip Yellow Mosaic Virus Replication.
Journal of Bacteriology and Virology 2011;41(2):109-116
Turnip yellow mosaic virus (TYMV) is a spherical plant virus that has a single 6.3 kb positive strand RNA genome. Information for TYMV replication is limited, except that the 3'-terminal sequence and 5'-untranslated region are required for genome replication. When a foreign sequence was inserted at the position upstream of the coat protein (CP) open reading frame (ORF), replication of the recombinant TYMV was comparable to wild type, as long as an RNAi suppressor was provided. In contrast, when the foreign sequence was inserted between the CP ORF and the 3'-terminal tRNA-like structure, replication of the recombinant virus was not detected. This result suggests that the CP ORF contains an essential replication element which should be appropriately spaced with respect to the 3'-end. Analysis of TYMV constructs containing a part or a full additional CP ORF indicates that the 3' quarter of the CP ORF is required for TYMV replication.

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.
