  • Extracutaneous mastocytoma is a rare benign tumor composed of mature mast cells and is located in tissues other than the skin. We report the case of a 61-year-old male who was diagnosed with extracutaneous mastocytoma via colonoscopic polypectomy and biopsy. To our knowledge, this was the first case of a solitary extracutaneous mastocytoma of the colon. We reported this case and reviewed the literature.

  • A potyvirus causing chlorotic mottle and yellow spots on leaves of Dianthus barbatus was isolated and identified as an isolate of Carnation vein mottle virus (CVMV). Purified preparations of Chenopodium quinoa infected with CVMV-K showed filamentous particles between 695 and 785 om long. Many cytoplasmic inclusions were observed, and these consisted of pinwheels, dense bands, loops, and circles. The coat protein of CVMV-K was about 32 KDa in western blot analysis using a CVMV antibody. The nucleotide sequence of coat protein gene showed 97.6% homology with a Japanese isolate. The genome size of CVMV-K was about 9.0 kb by dsRNA analysis. These results indicate that the virus is an isolate of CVMV. This is the first report on CVMV in Korea.

  • Most plants of commercial poinsettia cultivars grown from cuttings develop mosaic and chlorotic dot symptoms on leaves. Reverse transcription-polymerase chain reaction (RT-PCR) test showed that they were infected with Poinsettia mosaic virus (PnMV). In a survey of commercially grown poinsettias conducted in Korea, PnMV was detected in ten of ten poinsettia cultivars sampled and in 100% of 178 samples tested. The virus has isometric particles and about 29 nm in diameter. Crystalline virus particles were observed in cytoplasm of cells of diseased plants by transmission electron microscopy. Nucleotide sequence of coat protein gene of PnMV- Kl showed 97.3% homology with that of a German isolate. This is the first report on PnMV in Korea.

  • 일본 남부지역과 대만에만 분포하는 것으로 알려진 난과의 영주제비란(Platanthera brevicalcarata Hayata)가 제주도에서 발견되었다. 이 분류군은 근연종인 제비난초에 비해 식물체의 크기가 작고, 곁꽃받침에 한 개의 녹색맥이 뚜렷하게 있으며, 짧은 원통형의 거를 갖는 특징에 의해 구별된다. 국명인 영주제비란은 한라산의 지방명에 따라 명명하였다. 이 분류군에 대한 형태적인 특징과 도해를 생태 사진과 함께 제시하였다.

  • As the adult population continues to increase, orthodontic treatment for adult patients is becoming more common. This case report describes comprehensive orthodontic treatment of a middle-aged patient with closure of the extraction space without prosthetic restoration. A 55-year-old woman with her maxillary left first premolar extracted because of a periodontal problem, wanted to close the space with orthodontic treatment. Since she had generalized crowding and mild skeletal discrepancy, we planned comprehensive orthodontic treatment, including closure of the extraction space by protraction of the left maxillary molars using miniscrews and aesthetic alignment of anterior teeth. The total treatment period was 28 months. As a result of these treatments, the extraction space was successfully closed, good tooth alignment and satisfactory occlusion were achieved.

  • Bitter rot caused by the fungal genus Colletotrichum is a well-known, common disease of apple and causes significant yield loss. In 2013, six fungal strains were isolated from Fuji apple fruits exhibiting symptoms of bitter rot from Andong, Korea. These strains were identified as Colletotrichum fructicola and C. siamense based on morphological characteristics and multilocus sequence analysis of the internal transcribed spacer rDNA, actin, calmodulin, chitin synthase, and glyceraldehyde-3-phosphate dehydrogenase Pathogenicity tests confirmed the involvement of C. fructicola and C. siamense in the development of disease symptoms on apple fruits. This is the first report of C. fructicola and C. siamense causing bitter rot on apple fruit in Korea.

  • In October 2014, an occurrence of gray mold was observed on young fruits of sponge gourd (Luffa cylindrica) in Sachunmun, Gangneung, South Korea. Symptoms included abundant mycelia growth with gray conidia on young fruits and finally rotting the fruits. The fungus was isolated from symptomatic fruits and its pathogenicity was confirmed. Based on the morphological features and sequence analysis of ITS-5.8S rDNA, G3PDH, HSP60, and RPB2 genes, the pathogen was identified as Botrytis cinerea Pers. This is the first report of gray mold caused by B. cinerea on L. cylindrica in Korea.

  • Purpose: Dermatofibrosarcoma protuberans is a rare tumor, accounting for 0.1% of all malignant tumors. Although metastasis is very uncommon, local recurrence occur frequently. Dermatofibrosarcoma protuberans occurring in children is even more rare; this is the first case report of congenital dermatofibrosarcoma protuberans in Korea. Methods: The patient is a 14-month-old male infant with a lesion that was first thought to be a birthmark. The lesion grew larger, and a punch biopsy revealed dermatofibrosarcoma protuberans. A wide local excision was performed with a 2 cm peripheral resection margin beyond the gross tumor lesion. Deep fascia and a portion of muscle underneath the central part of the lesion were also taken. The surgical defect was covered by a split-thickness skin graft. Results: There has been no clinical sign of recurrence over one year after the surgery. Conclusion: A patient with congenital dermatofibrosarcoma protuberans detected at an early stage underwent a wide local excision of the tumor after accurate diagnosis was carried out by biopsy and immunohistochemical studies. There was no clinical evidence of tumor recurrence during over a 1-year follow-up.

  • Esophageal atresia and tracheoesophageal fistula may occur as separate entities but usually occur in combination.The first report of esophageal atresia with tracheoesophageal fistula was done by Thomas Gibson in 1696.In1941, Haight and Towlseg performed the first successful primary repair,recently we were experienced a case of esophageal atresia with distal tracheoesophageal fistula in infant patient who presented the symptoms of dyspnea and vomiting.The operation was performed transpleurally through right 4th intercostal space.Patient tolerated all the operative procedure and recovered uneventflly.He was well-being without other problem.

  • Prosthetic valve replacement has resulted in marked improvement in the functional status of many patients with valvular heart disease. But valve failure from various causes has necessitated re-replacement of prosthetic valve in some of these patients. This selective group of patients has many inherent problems. This report presents our experience with seven patients who received re-replacement of prosthetic valve in the Seoul National University Hospital from 1981, to 1983. The patients included one woman and six men in the range of 9 and 49 years old. As the first valve operations, there were five MVR using tissue valves, one DVR [Bjork-Shiley and Ionescu-Shiley valve] and one case of modified Bentall operation with composite graft [Ionescu-Shiley valve]. Reoperations on prosthetic valve failure were performed 17 to 54 months after the first operation [mean 34 months]. Amon8 seven patients, there were two cases of prosthetic valve endocarditis and five cases of primary tissue failure. Gross calcification of the xenograft was found in two children with Ionescu-Shiley valve. All except one had relatively successful operative results. The unsuccessful one died intraoperatively from low output syndrome.
