  • A gray mold disease occurred on Cryptotaenia japonica in Korea. All the isolates of Botrytis sp. from the lesions of the diseased plants were identified to be B. cinerea based on the morphological characteristics. Conidia formed on conidiogenous cells were not in chains, hyaline to pale brown, unicellular, ellipsoidal to obovate with a single hilum at the base, entirely verruculose, and $6.3-11.3{\sim}6.3-10.0{\mu}m$ in size. Pathogenicity of the fungus was proved by artificial inoculation on C. japonica. This is the first record of gray mold on C. japonica caused by B. cinerea in Korea.

  • The hemal nodes of the Korean native cattle were studied by gross anatomy and light microscopy. Hemal nodes were spherical or ovoid in shape, and red or black in colors. A hemal node consisted of a thick capsule and a hilum, and had extensive subcapsular and deep sinuses distended by a great number of erythrocytes. Although a few lymphatic nodules and tissues were seen in the parenchyma, no typical cortex and medulla was defined. Blood vessels occurred, but lymph vessel was not observed in nodes. The stroma of the hemal node was composed of reticular cells and fibers. The parenchyma consisted of many erythrocytes and lymphocytes, and a few macrophages and megakaryocytes. The capsule and trabecula was a collagenous connective tissue with smooth muscle cells. B-lymphocytes were principally located in the lymphatic nodules of the hemal node. T-lymphocytes were scattered in the diffuse lymphatic tissues of the hemal node.

  • 선천성 기관지 폐쇄증은 단순촬영에서 폐 결절로 보여 악성 종양으로 오인될 수 있다. 그러나 흉부단순촬영과 특히 전산화단층촬영에서는 늘어난 기관지 내의 점액고착, 구역 과팽창 등이 특징적으로 보여 더 이상의 침습적 검사 없이 선천성 기관지 폐쇄증으로 진단할 수 있다.

  • Eight patients underwent tracheal resection and reconstruction for tracheostomy and postintubation injuries from 1971 to early 1981. The ages ranged from 12 years to 59 years. The patients had 7-cuff stenosis and one stomal lesion in whom intubated long. Four male and four female patients were treated. Cervical approach was used in one, cervicomediastinal in 3 and transthoracic in four. The longest length of resection extended to 4 cm in whom cervico-upper half mediastinal incision and neck flexion were applied. Techniques for obtaining tension-free anastomosis included cervical flexion or division of the inferior pulmonary ligament and mobilization of the right hilum. Concurrent tracheostomy was not needed in all. There was one death at the end of emergency operation from anesthetic accident. Granulations at the anastomosis line, necessitating bronchoscopy, were noted in two and the lesion did not recurred after removal. No restenosis or other complications occurred during long follow-up.

  • Pulmonary hamartoma is relatively common among the benign tumors of lung, and is credited to Albrecht who In 1904 described a disorganized arrangement of tissue normally present In an organ. But hamartoma has rare incidence of total pulmonary tumors, and especially endobronchial origin is extremely rare. We have experienced three cases of pulmonary hamartoma Including one bronchial origin. First case was a 27 years old woman who had multiple hamartomas, located all in right middle lobe and middle lobectomy was performed. Second case, a 56 years old woman, had endobronchial hamartoma, l x l .5x l .8cm in size and located at right intermediate bronchus. Right pneumonectomy was Inevitable because of It`s proximal location near the hilum. Third case, a 55 years old man, revealed sclerosing hemangioma microscopically, 4x4x5 cm In size, in right lower lobe and right lower lobectomy was performed. Postoperative course of all of them were uneventful and discharged with good general condition on the ~ 4th to 26th day postoperatively.

  • Lipoxygenase and Kunitz trypsin inhibitor protein of mature soybean [Glycine max (L.) Merr.] seed are main anti-nutritional factors in soybean seed. A new soybean cultivar, "Gaechuck#1" with the traits of black seed coat, green cotyledon, lipoxygenase2,3 and Kunitz trypsin inhibitor protein free was developed. It was selected from the population derived the cross of "Gyeongsang#1" and C242. Plants of "Gaechuck#1" have a determinate growth habit with purple flowers, brown pubescence, black seed coat, black hilum, oval leaflet shape and brown pods at maturity. Seed protein and oil content on dry weight basis have averaged 39.1% and 16.2%, respectively. It has shown resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. "Gaechuck#1" matured on 5-10 October with a plant height of 50 cm. The 100-seed weight of "Gaechuck#1" was 23.2g. Yield of "Gaechuck#1" was averaged 2.2 ton/ha from 2005 to 2007.

  • Lipoxygenase and Kunitz trypsin inhibitor protein are the main antinutritional factor in mature soybean seed. A new soybean cultivar, "Gaechuck#2" with yellow seed coat, lipoxygenase2,3-free and Kunitz trypsin inhibitor protein-free was developed. It was selected from the population derived from the cross between "Jinpumkong2ho" and C242. Plants of "Gaechuck#2" have determinate growth habit with purple flowers, tawny pubescence, yellow seed coat, yellow hilum, oval leaflet shape and brown pods at maturity. Seed protein and oil content on a dry weight basis were 40.7% and 18.7%, respectively. It has shown a resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. Gaechuck#2 matured in 4 October with plant height of 54cm and a 100-seed weight of 24.4g. Average Yield of Gaechuck#2 was 230 - 250 kg/10a in 2005 - 2007.

  • We have discovered Vicia grandiflora Scop., a newly invasive alien species in Baekun-ri, Okcheon-gun, Chungcheongbuk-do, Korea. This species is native to regions from Central and Southeast Europe to Central Asia and Iran and is reported as an invasive species in North America and Japan. This species is similar to the Vicia sativa complex (V. sativa subsp. sativa, V. sativa subsp. nigra) but can be readily distinguished by the undivided ovate to semi-hastate stipules of the upper leaves, yellowish petals, large size of its flower, and elongated hilum. In the field, V. grandiflora grows in disturbed sites near cultivated land, suggesting that their seeds are typically transported by vehicles along with fertilizer or livestock feed. Here, we present the morphological description, photographs, and sites of V. grandiflora growth, which will be useful in guiding the management of this invasive alien plant.

  • Soybean sprouts have been a considered a nutrient-rich vegetable for hundreds of years. To evaluate the seedlot quality of soybean sprouts grown, and to evaluate a method for reducing the presence of improper seeds in soybean seedlots, microbes associated with soybean sprout rot were isolated from samples collected. Morphological characteristics and gas chromatography profiles of the cultured fungal and bacterial strains were identified. Eight types of improper seeds were identified: purple stain(Ps), black rot(Br), seed coat black spot(Cb), wrinkled seed(Ws), brown hilum(Bh), seed coat fracture(Cf), unripe seed(Us), and brown seed coat(Bc). The improper seeds were also dipped into 15%, 20%, and 25% NaCl solutions, as well as a saturated solution of NaCl, for 1min. As the NaCl concentration increased, the number of floating improper seeds increased as well. The highest floating rates were observed for the Cf seeds.

  • A 64-year-old man was admitted due to jaundice for 2 weeks. Radiologic findings revealed biliary stricture at the hepatic hilum with intrahepatic duct dilation suggesting Bismuth type IV Klatskin tumor. Jaundice improved spontaneously several days after hospitalization. Surgical treatment was considered but he only wanted to observe without specific treatment. Ten months later, he was re-admitted due to the recurrence of jaundice. Computed tomography (CT) showed no significant difference compared to previous results. Serum cancer antigen 19-9 and Immunoglobulin G4 were normal. Endoscopic forcep biopsy during endoscopic retrograde cholagiopancreatography (ERCP) revealed chronic inflammation. After steroid use under possible diagnosis of IgG4 related cholangiopathy, biliary stricture improved slightly. Four years later, he was hospitalized with the occurrence of acute cholangitis. Endoscopic retrograde biliary drainage was performed following endobiliary forcep biopsy. Pathology revealed well-differentiated adenocarcinoma at this time. Combined chemotherapy based on gemcitabine and cisplatin was performed. Six months later, CT revealed partial response.
