Eight species of Marssonina parasitic on 21 species of host plants from Korea are described and illustrated. They are Marssonina brunnea (Ellis & Everh.) Magnus, M. capsulicola (Rostr.) Magnus, M. celastri H.D. Shin & H.T. Lee, M. coronaria (Ellis & Davis) Davis, M. fragariae (Lib.) Kleb., M. juglandis (Lib.) Magnus, M. rosae (Lib.) Died. and M. sennenis (Gonz. Frag.) Vassiljevsky & Karak. Of these, M. capsulicola and M. coronaria sometimes poss three-celled conidia and M. sennenis is characterized by a short appendage at the basal end of the conidia. Morphological features of conidia and host ranges were of taxonomic values for species delimitation.

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.

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.

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.

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.

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.

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.

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.

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.
