The study was carried out to investigate the effects of dietary carotenids and β-carotene on the hematological changes caused by alcohol administration into the rats. The results were analyzed using several statistical methods; SPSS computer program for measuring the mean values and standard deviations, one way ANOVA for the test of significance, Duncan method for post HOC multiple comparison, and Pearson method for measuring the correlation coefficient. The following are the conclusion from those statistical analysis. 1. ALB and TB were shown to have the most significant correlation among the blood compositions f개m the basic dietary groups. 2. BUN and CHO were shown to have the most positive correlation among those from the carrot-fed groups. 3. CA and AG were shown positively correlated, and CHO and IP negatively correlated, respectively among those from the cheese-fed groups. 4. AP was shown positively correlated among those from the alcohol-administrated groups. 5. CHO, CA and BUN were shown positively correlated, and CA was negatively correlated among those from the β-Carotene -fed groups. 6. TB and TP were not affected by the correlations between the blood composition from all the experimental groups.

This study has been conducted to investigate the genetic and ecological variation of wheat culm length measured from those plants grown at greenhouse. The results are as following. 1. The clum length of the winter wheat was higest under 12hrs daylength, while that of the spring wheat was highest under 8hrs daylength. Standard errors of culm length was larger under 12 and 8hrs daylength than that of 24hrs daylength condition. 2. The culm length was shortest under the 24hrs daylength compare to under 12 or 8hrs while it was highest under 12hrs. Short and medium culm length varieties were photo-insensitive but those of long culm length were photo-sensitive. 3. There are many types of varietal differences for the culm length under the daylength conditions. Highest culm length group under 12 and 8hrs conditions was classified. The semi-dwarf varieties that did not change their plant heights under i and 12hrs conditions were Hira, Yecora Resel, Sava, Sturdy, Saric 70, Sekidorisai 66etc. 4. Varietal difference of culm elongation was noticed between 8hrs and 12hrs daylength condition. On the basis of the evidences obtained from this experiment, it may be concluded that the genetic studies related to culm length should be carried out under the most favorable conditions for culm elongation. 5. Correlation coefficients estimated between culm length and heading or maturity were negative but insignificant, but their correlations were highly significant between photo treatments. 6. Culm length of F_1 was intermediate to the range of F_2 population which seems to be distributed normally. In this regard the gene involved with culm length seemingly inherit additively. Statistical analysis for the involved genes for culm length suggested 2 genes for the semidwarf variety Robin #2.

Purpose : This study aimed to investigate the luminal stenosis of the internal carotid artery with calcification detected on panoramic radiographs. Materials and Methods : This study used fifty carotid arteries of 36 dental patients whose panoramic radiograph and computed tomography angiography (CTA) revealed the presence of carotid artery calcification. A neuroradiologist interpreted CTA to determine the degree of stenosis of the internal carotid arteries. The degree of stenosis was stratified in four stages; normal (no stenosis), mild stenosis (1-49%), moderate stenosis (50-69%) and severe stenosis (70-99%). Results : Among the fifty carotid arteries with calcification detected on both panoramic radiography and CTA, 20 carotid arteries (40%) were normal, 29 carotid arteries (18%) had mild stenosis, 1 carotid artery (2%) had moderate stenosis, and there was none with severe stenosis. Conclusion : Sixty percent of the carotid arteries with calcification detected on both panoramic radiography and CTA had internal luminal stenosis, and two percent had moderate stenosis. When carotid atheroma is detected on panoramic radiograph, it is possible that the dental patient has luminal stenosis of the internal carotid artery.

The objective of this study was to remove organics and color in livestock wastewater using coagulation and Fenton oxidation process. After coagulation process as 1^(st) treatment, organics in 1^(st) treatment water were removed by using OH radical produced in Fenton oxidation process. Removal efficiencies of COD_(Mn) and color were 87.2% and 95.7% separately. At that time, the ratio of Fe^(2+)/ H₂O₂ was 0.8∼1.0, and range of reaction pH was effective at the pH of 3.5∼3.8. The Reaction time of 120min more than 60min or 90min was sufficient in Fenton process. Removal efficiency of organics was higher two- or multi-stage treatment than one-stage treatment.

Experimental model which are able to determine the deviation between weld line and weaving center by measuring the weld current during welding were proposed for the gas metal arc welding process. The models were developed by using the filtered current signals and filtered-averaged ones for the various welding conditions. The models were used for developing a weld seam tracking system which controls the weaving speed of a welding torch. It could be shown that there is a successful capability of seam tracking in flat welding of V-grooved butt Joints. Comparing the weld current signal processing methods, the models of filtered signal showed better tracking ability than those of filtered-averaged signal.

Vocal cord dysfunction (VCD) is a respiratory disorder characterized by the abnormal adduction of the vocal cords upon inspiration, expiration, or both, leading to a diverse array of acute obstructive airway signs and symptoms (wheezing, chest tightness, shortness of breath, and cough). VCD frequently mimics or confounds asthma. Misdiagnosis as asthma has led to inappropriate treatment, most notably with high-dose corticosteroids. Mistaken for anaphylaxis or angioedema, VCD has led to intubation and tracheostomy. VCD should be suspected in patients who are treated aggressively for asthma but continue to experience dyspnea. The diagnosis of VCD is made from direct visualization of the vocal cords during an attack. Inspiratory, anterior vocal cord closure with a posterior glottic chink is seen. On pulmonary function testing, a pattern of "saw-toothing", or fluttering of the inspiratory limb, representing fluctuations in the abnormal cord motion is seen in VCD patient. Treatment includes discussion of the diagnosis with the patients, discontinuing unnecessary medications, using of a helium-oxygen mixture in acute attack. Speech therapy and psychotherapy are the mainstays of long-term treatment. Here in we report a case of VCD in company with asthma.

Silicon alkoxides(TEOS:tetraethylorthosilicate and TMOS:tetramethylorthosilicate) were synthesized from silicon tetrachloride and ethanol or methanol with the variation of the mole ratio (alcohol/SiCl_4) and the water contents in the alcohol. The optimum mole ratios of alcohol/SiCl_4 were measured to be betweem 4 and 5 and the reactions completed within one hour. The yield of TEOS decreased from 70% to 48% as the water contents increased from 0.1% to 1.0% in ethanol.

관상동맥조영술중 비이온성 조영제 Iodixanol (Visipaque®)에 의해 발생한 아나필락시양 반응 1예

흉통을 주소로 내원한 45세 남자에서 관상동맥조영술 중 비이온성 조영제에 의하여 아나필락시양 반응이 발생한 증례를 경험하였기에 보고하는 바이다. Radiocontrast agent infusion is the most common cause of non-IgE mediated anaphylactoid reaction in the modern medical procedures. The newer lower-osmolar nonionic contrast agents cause significantly lower adverse reactions than the high-osmolar ones. However, anaphylactoid reaction to nonionic contrast agent can cause life-threatening events and even death has been rarely reported. Iodixanol (Visipaque®) is a nonionic, dimeric contrast agent, which is currently used in cardiac catheterization. Here we report a case of anaphylactoid reaction to Iodixanol, a nonionic radiocontrast agent, during cardiac catheterization. A 45-year-old male patient underwent cardiac catheterization for evaluation of substernal pain during exercise. Five minutes after this contrast injection to the left coronary artery, he complained itching and dizziness. Subsequently, generalized urticaria, cyanosis and hypotension were developed. His coronary angiogram showed normal findings. He was treated with intravenous fluids, intravenous diphenhydramine, sucutaneous epinephrine and sympathomimetics and one hour later he recovered. This case suggests that anaphylactoid reaction to a radiocontrast media, iodixanol, should be considered in the list of differential diagnoses for cardiopulmonary arrest during cardiac catheterization.
