Alternaria tenuis, Arthrobotrytis sp. Aspergillus spp. Chaetomium sp. Caldosporium sp. Cuvularia lunata, Mucor sp. Nigrospora sp. Pencillium spp. Phoma sp. Rhizopus sp. Stachybotrytis sp. Stemphylium sp. Trichotehcium sp. and Ulocladium sp. were saprophytic fungi and Drechslera graminea, D. rostrata, D. sorokiniana, D. tetramera, and Fusarium graminearm were pathogenic fungi detected from 40 seed samples of wheat and barley. Initial symptoms caused by D. graminea, D. sorkiniana and F. graminearum on seedlings from naturally infected seed by the test tube agar method have been described and discussed. Surface-sterilized barley seedlings became diseased in the test tube agar artificially inoculated with D. graminea, D. sorokiniana, D. tetramera and F. graminearum isolated from naturally infected barley seeds. But wheat seedlings became diseased with D. rostrata, D. sorokiniana and F. graminearum when artificially inoculated. New records for Korea are D. tetramera from barley seeds and D. rostrata from wheat seeds. Seed disinfectants of Sisthane and Benlate Thave equal effect to Vitathiram against Ustilago nuda and D. graminea. Baytan U was effective against loose smut but inferior to leaf stripe of barley. Prolaz was effective against leaf stripe but inferior to loose smut of barley.

The problem of sound radiation from infinite elastic beams under the action of harmonic moving line forces is studied. The reaction due to fluid loading on the vibratory response of the beam is taken into account. The beam is assumed to occupy the plane z=0 and to be axially infinite. The beam material and elastic foundation are assumed to be lossless and to follow Bernoulli-Euler beam theory including a tension force (T), damping coefficient (C) and stiffness of foundation (K_S). The non-dimensional sound power is derived through integration of the surface intensity distribution over the entire beam. The expression for sound power is integrated numerically and the results are examined as a function of Mach number(M), wavenumber ratio(r) and stiffness factor(T). Here, the purpose is to explain the response of sound power over a number of non-dimensional parameters describing tension, stiffness, damping and foundation stiffness.

Background & objectives : An increase of calcium influx during alcohol withdrawal state may contribute to neuronal hyperexitability, which cause delirium tremens(DT). Some investigators have found calcium channel blockers effects in prevention of DT in experimental animals. Therefore we evaluated the preventive effects of calcium channel blocker(nimodipine) and benzodiazepine(chlordiazepoxide) on the development of DT in alcohol withdrawal seizure(AWS) patients. Method : A total 59 patients with AWS were divided into three groups according to the management nimodipine-treated, chlordiazepoxide-treated, and control(no specific medication) groups. We compared the incidence rates of DT in the three groups. Results : Total incidence rate of DT was 30.5%(18 of 59 patients). There were 6 DTs of 18 patients(33.5%) in nimodipine-treated group, 4 of 21 patients(22.5%) in chlordiazpoxide-treated group, and 8 of 20 patients(44.0%) in control. Conclusion : The control group(44.0%) showed the highest incidence rate of DT. And nimodipine-treated(33.5%) and chlordiazepoxide-treated group(22.5%) were followed. However, this result failed to demonstrated statistically significant differences due to small numbers size.

Three species of Colletotrichum Corda and Glomerella cingulata(Stonem). Spauld. & v.Schr. known to cause ripe fruit rots of apple, peach and pepper in Korea are compared with respect to culture characteristics, morphology, temperature reactions and pathogenicity determined by field collection and artificial inoculation. The following 4 species and 3 strains of anthracnose fungi reconized : C. coccodes (Wallr). Hughes, C. dematium (Pers. ex Fr.)Grove, C. gloeosporioides(Penz.) Sacc. G, chromogenic, and non-chromogenic strain and G. cingulata. The characteristic features of these organisms are discussed and on the evidence available it is found desirable to designate a new form of C. gloeosporioides or new species of Colletotrichum. It appears that the differences in virulence is not only among the different species of Colletotrichum and G. cingulata but also between isolates of the same species. C. dematium, G. gloeosporioides and G. cingulata are detected in seed samples of red pepper (Capsicum annuum) and C. gloeosporioides are the predominant species in seeds of red pepper which are naturally infected with anthracnose in field conditions. Plating of seed components showed that three species of anthracnose fungi are detected from seed coat, endosperm and plumule bud. C. dematium, C. gloeosporioides and G. cingulata caused seed rot, damping-off and seedling blight. In the effect of some fungicides to C. dematium and C. gloeosporioides on red pepper, Difolatan was the most effective to the fruit rot followed by Orthocide and Phaltan.

Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.

Damping-off and wilting diseases in sesame plant(Sesamum indicum L.) occurring severely in Korea have been studied for incidences of disease from seeds, diseased plants and soils. Alternaria longissima, A. tenuis, Aspergillus. spp, Cephalosporium sp., Cuvuaria lunata, Drechslera sp.,sp., Fusarium equiseti, F. moniliforme, F. semitectum, F. solani, Mucor sp., Myrothecium roridum Penicillium spp., Phoma sp., Rhizopus sp., were saprophytic fungi and Alternaria sesami, A. sesamicola, Macrophomina phaseolina, Rhizoctonia solani were pathogenic fungi detected from 66 seed samples of sesame. Initial symptoms caused by pathogenic fungi on seedlings from naturally infected seed by the test tube agar method have been described and discussed. Except Alternaria sesamicola, A. tenuis and Macrophomina phaseolina, all fungi were completey wiped out the infection by pretreatment with Benlate-T. The pathogenic fungi isolated from sesame soil were Fusarium oxysporum and Rhizoctonia solani. F.oxysporum occurred less frequently in upland rice and ground nut soils than in sesame soil, but R. solani not decreased by upland rice and ground nut soils. The differences of the isolation frequency of F.oxysporum and the incidence of the wilting plants were found among the fields which varied in their cropping histories. F.oxysporum isolated most frequently from stems and roots of wilting sesame plants followed by R. solani. Nematodes also isolated from the wilting sesame plants.

Background: The management of vertiginous patients is a great challenge to emergency physicians. We evaluated the diagnostic value of a diffusion-weighted image(DWI) in differentiating central vertigo from the peripheral vertigo in patients who presented no neurological symptoms other than risk factors for stroke. Methods: From March 2000 to February 2001, we retrospectively analyzed the cases of 68 patients who visited the emergency department with symptoms of isolated vertigo and who had risk factors for stroke. DWIs, computed tomograms(CT), and medical records were reviewed, and the final diagnose, the DWIs and the CT readings, the risk factors for stroke, and the time it took waiting for a DWI or CT scan were analyzed. Results: Of the 68 patients, 21(30.8%) had central vertigo: 15 vertebrobasilar transient ischemic attacks(VB-TIA), 4 brain stem infarctions, 1 cerebellar infarction, and 1 cerebellopeduncular infarction. The DWI showed a 28.6% sensitivity, a 97.9% specificity, and an 85.7% positive predictive value in diagnosing central vertigo. It also had a 100% sensitivity in detecting infarctions. Conclusion: A DWI had a comparable sensitivity to MRI in detecting central vertigo and small, but potentially, lethal infarctions in our patient population. We recommend clinical application of DWI in the emergency department evaluation of isolated vertigo patients with risk factors for stroke.
