Identification and Characterization of Alternaria iridiaustralis Causing Leaf Spot on Iris ensata in China

In 2016, a severe leaf spot disease was found on Iris ensata Thumb. in Nanjing, China. The symptom was elliptical, fusiform, or irregularly necrotic lesion surrounded by a yellow halo, from which a small-spored Alternaria species was isolated. The fungus was identified as Alternaria iridiaustralis based on morphological characteristics. The pathogenicity tests revealed that the fungus was the causal pathogen of the disease. Phylogenic analyses using sequences of ITS, gpd, endoPG, and RPB2 genes confirmed the morphological identification. This study is the first report of A. iridiaustralis causing leaf spots on I. ensata in China.

Alternaria brassicifolii sp. nov. Isolated from Brassica rapa subsp. pekinensis in Korea

A new species belonging to the genus Alternaria was isolated from the necrotic leaf spots of Brassica rapa subsp. pekinensis in Yuseong district, Daejeon, Korea. It is an occasional isolate, not an etiological agent, which is morphologically similar to A. broccoli-italicae, but differs in conidial size and conidiophore shape. Phylogenetic analysis using the sequence datasets of the internal transcribed spacer (ITS) region of the rDNA, glyceraldehyde-3-phosphate dehydrogenase (gpd), and plasma membrane ATPase genes showed that it is distantly related to A. broccoli-italicae and closely related to Alternaria species in the section Pseudoalternaria, which belonged to a clade basal to the section Infectoriae. Morphologically, the species is unique because it produces solitary conidia or conidial chains (two units), unlike the four members in the section Pseudoalternaria that produce conidia as short branched chains. It exhibits weak pathogenicity in the host plant. This report includes the description and illustration of A. brassicifolii as a new species.

Characterization and Pathogenicity of New Record of Anthracnose on Various Chili Varieties Caused by Colletotrichum scovillei in Korea

The anthracnose disease caused by Colletotrichum species is well-known as a major plant pathogen that primarily causes fruit rot in pepper and reduces its marketability. Thirty-five isolates representing species of Colletotrichum were obtained from chili fruits showing anthracnose disease symptoms in Chungcheongnam-do and Chungcheongbuk-do, South Korea. These 35 isolates were characterized according to morphological characteristics and nucleotide sequence data of internal transcribed spacer, glyceraldehyde-3-phosphate-dehydrogenase, and β-tubulin. The combined dataset shows that all of these 35 isolates were identified as C. scovillei and morphological characteristics were directly correlated with the nucleotide sequence data. Notably, these isolates were recorded for the first time as the causes of anthracnose caused by C. scovillei on pepper in Korea. Forty cultivars were used to investigate the pathogenicity and to identify the possible source of resistance. The result reveals that all of chili cultivars used in this study are susceptible to C. scovillei.

Identification and Characterization of New Record of Grape Ripe Rot Disease Caused by Colletotrichum viniferum in Korea

In 2016, grape fruits showing ripe rot symptom were found in fields of Korea. The fungus was isolated and identified as Colletotrichum viniferum based on morphological characteristics and nucleotide sequence data of the internal transcribed spacer, glyceraldehyde-3-phosphate dehydrogenase and β-tubulin. To our knowledge, this is the first report of C. viniferum causing grape ripe rot disease of grape fruits in Korea.

First Report of Anthracnose Caused by Colletotrichum fioriniae on Chinese Matrimony Vine in Korea

A fungus, Colletotrichum fioriniae, was isolated for the first time from fruits of Chinese matrimony vine (Lycium chinense Mill.) in Korea. It was classified as C. fioriniae based on the morphological characteristics and nucleotide sequence of glyceraldehyde-3-phosphate-dehydrogenase and β-tubulin. To the best of our knowledge, this is the first report of C. fioriniae causing anthracnose of Chinese matrimony vine in Korea.

Central pain after thalamic stroke: clinical and radiological characteristics

BACKGROUND AND OBJECTIVES: Although pain resulting from thalamic stroke was described by D jerine & Roussy in 1906, its pathomechanism & anatomical substrate have not been defined yet. Several clinical & experimental studies suggest that laterality of lesion for generation of central pain is as important as location of lesion. We performed this study to evaluate clinical features of thalamic pain syndrome, including incidence, onset interval from stroke, nature, distribution, accompaniments, and to assess the relationships between laterality & location of lesion and occurrence of pain. METHODS: We reviewed the medical records and brain imaging of all patients with thalamic stroke from 1990 to 1997. Patients with thalamic pain syndrome due to a single well-demarcated thalamic stroke were included, and excluded tumoral, non-vascular etilogy, and patients with sensory deficit without pain and excluded patients who had multiple cerebral lesions even they have thalamic pain syndrome. RESULTS: One-hundred one cases were selected under the inclusion criteria, and twenty-four patients(24%) with thalamic pain syndrome were identified from 101 thalamic stroke. Pain onset within the first week poststroke was 17(71%). The patients with allodynia were 8(33%), increased by movement, stress, and thermal contact. The painful area distributed mainly limbs(50%), especially arm(35%), face plus hemibody(34%), and hemibody below face(8%). Thalamic pain syndrome accompanied with the pain and temperature loss was 17(71%). Thirteen patients had a right-sided lesion, 11 left-sided lesion. The lesion causing thalamic pain syndrome mainly located in the posterolateral areas(75%). CONCLUSIONS: We conclude that the thalamic pain syndrome resulting from mainly posterolateral thalamic lesion cause the spontaneous pain on the contralateral body, especially upper extrimity, and accompanied with pain & tempterature loss. The laterality of lesion is not represent for generation of thalamic pain syndrome. Key word : thalamic stroke, central pain.

A Clinical Study on Ipsilateral Fracture of the Femur and Tibia / 대한정형외과학회잡지

Thirty-three cases of the fracture of the femur and tibia on the same limb were treated at the Orthopedic Department of the Chosun University Hospital during the period from January 1977 to December 1983. The following results were obtained. 1. The incidence of trauma was high in the young man, most frequent in the third decade (45.4%). 2. The most common cause of the fracture was traffic accident (81;8%). 3. The most common shape of the fracture was comminuted in both femur and tibia. 4. The common fracture site were middle one-third in both femur and tibia. 5. Eight patients were treated by conservative means on both femxr and tibia. The patients were treated by internal fixation on femur and by conservative means on tibia. Internal fixation was .done in ten patients on both femur and tibia. Two patients were treated by inteinal fixation on tibia and by conservative means on femur. Three patients were amputated. 6. Average healing time of fracture was 21 weeks in femur and 24.2 weeks in tibia. 7. Functional end results were assessed and rated with satisfactory results in rigid internal fixation of the femur and tibia.

A Clinical Analysis of the Fracture of the Forearm Bone / 대한정형외과학회잡지

From January 1979 to December 1983, eighty-five patients who had forearm bone fracture were treated by four different methods at the Department of Orthopedic Surgery, Chosun University Hospital. The results were as follows: 1. Among 85 patients, 12 patients were radius fractures, 19 patients were ulna fractures, 54 patients were both forearm bone fractures. 2. Closed fractures were 70 patients and the open fractures were 15 patients. 3. The mst common fracture site was middle third of the both radius and ulna. 4. The treatments were closed reduction with cast immobilization, intramedullary nailing or plate and screw fixation. 5. The time required for radiological bone union were shorter in compression plate fixation gmup, than those treated with other fixation device. 6. Functional result was claasified according to the rating system of Smith and Sage. The open reduction and internal fixation group had better results than the conservatively treated group.

Clinical Study for Open Fracture of Tibia / 대한정형외과학회잡지

118 Cases of open tibia fractures treated in Chosun university Hospital were survayed and evaluated. Results: 1. The cases are predominantly male(80%) and most often in their 4th decade. 2. They were very often comminuted(44%) 3. Treatments consists of debridement with or without initial internal(plate and screws) or external (Hoffmann's device) fixations. The end results seems to be better in cases with initial fixations of bone(internal or external)than those treated with initial debridement and plaster cast immobilization only and osteosynthesis later.
