The antigenicity of intralipidos was investigated in guinea pig, mice and rats. Antigenicity tests-active systemic anaphylaxis (ASA), passive systemic anaphylaxis (PSA), passive cutaneous anaphylaxix (PCA) of this materials were performed. The results were followed: 1. After sensitizaion with YPL, YPL+intralipidos, and intralipidos, emulsified with complete Freund's adjuvant (CFA), guinea pigs didn's show any anaphylatic shock symptom in the ASA test, 2. These materials didn't show any anaphylatic shock symptom in the PSA test, 3. After sensitization with antisera of YPL, YPL+intralipidos, and intralipidos sensitized mice, blue spots were not observed on the hypodermis of back of rats in the PCA test. From the results of this investigation, the antigenicity of YPL, intralipidos was negative under the present experimental condition.

The potential of three plants extracts, to protect potato plants against bacterial wilt caused by Ralstonia solanacearum was determined under greenhouse and field conditions. All soil drenching treatments of aqueous plant extracts of Hibsicus sabdariffa, Punica granatum and Eucalyptus globulus significantly reduced the disease severity compared with inoculated control. Although the applications of all three plant extracts resulted in similar reductions of disease severity in field up 63.23 to 68.39%, treatment of E. globulus leaf extract was found greater in restricting the symptom development than other the two plant extracts in the greenhouse. More than 94% reduction in the bacterial wilt symptom was observed in potato plants. All tested plant extracts were effective in inhibiting the growth of bacterial pathogen, not only in vitro, but also in stem of potato plants as compared with the inoculated control Potato plants treated with extract of H. sabdariffa reduced bacterial growth more effectively than treatment with P. granatum and E. globulus. Activity of defence-related enzymes, including peroxidase, polyphenoloxidase and phenylalanine ammonia lyase, were significantly increased in plants treated with the plant extracts compared to the control during the experimental period. In general, the higher enzymes activities were determined in both inoculated and non-inoculated treated potato plants after 8 days from plant extracts treatment. These results suggested that these plant extracts may be play an important role in controlling the potato bacterial wilt disease, through they have antimicrobial activity and induction of systemic resistance in potato plants.

Purpose : This study aims to examine hospital employees' subjective symptoms of VDT syndrome (Video display terminal syndrome) and figure out their effects on health conditions and correlations. Materials and Methods : This study used a structured self-administering questionnaire and gained data from 125 subjects. The questionnaire consists of total 62 questions, and they went through real number, percentage, ${\chi}^2$-terst, t-test, one-way ANOVA, and logistic regression analysis. Results : Regarding the difference in the types of subjective symptoms of VDT syndrome by jobs, there was statistically significant difference in ophthalmic symptoms, systemic symptoms, and musculoskeletal symptoms. About the correlation between the subjective symptom points of VDT syndrome by the types of symptoms, there was statistically significant correlation all in skin trouble, backache, upper limb muscle pain, lower limb muscle pain, fatigue in the head and eyes, and depression or anxiety disorders. There was significant correlation between the subjective symptom points of VDT syndrome and subjective health conditions. Conclusion : Hospital employees' subjective health conditions had significant correlation with subjective symptom points of VDT syndrome. This result shows that as radiologists' and also other hospital employees' working conditions change into VDT environment, VDT syndrome gradually appears more and more. This implies that it is needed to designate not only radiologists but also all the other hospital employees as jobs exposed to the working environment of VDT syndrome and provide preventive measures, education, and publicity for it afterwards.

To develop an effective protection strategy against tomato bushy stunt virus (TBSV), tobacco plants expressing single-chain Fv antibodies (scFv), were established. A previous had shown that the replication activity of viral replicase was inhibited by the selected scFvs. Moreover, no systemic symptom was found after virus inoculation on leaves of wt N. benthamiana infiltrated with an Agrobacterium suspension resulting i3l expression of the scFvs. However, control plants showed systemic symptoms. In this study the localization of the scFvs within two transgenic plant lines, (CP28H3, CP-P55) was demonstrated using immunogold labelling. The gold particles, indicating the presence of scFv, were mostly found In the cytoplasm of the plant cells including chloroplasts and in the cell walls. However, they were hardly found in the vacuole, nucleoplasm and intercellular spaces. Gold particles often accumulated in either the cytosol or chloroplasts showing a specific labeling, There was no difference in type of gold labeling between both transgenic lines. The localization of the scFv in the cytoplasm further conforms the inhibition of the RNA-dependent RNA polymerase (RdRp) by the selected scFv because it is known that the RdRp is localized to membraneous cytosolic structures.

An infectious full-length clone of Soybean mosaic virus (SMV) strain G5H was constructed under the control of the cauliflower mosaic virus 35S promoter. The cloned SMV G5H established infections upon simple rub-inoculation of soybean leaves with intact plasmid DNA. We demonstrated that this SMV G5H infectious DNA clone caused typical characteristic symptoms and virulence of SMV strain G5H in twelve tested soybean cultivars. Soybean cultivars Lee74, Somyungkong and Sowonkong developed systemic mosaic symptom while Kwanggyo, Taekwangkong, Hwangkeumkong and Geumjeongkong-l showed systemic necrosis. In contrast, Geumjeongkong-2, Jinpumkong-2, L29, V94-5152 and Ogden showed resistant response against SMV-G5H infection. We also determined full-length sequence of cloned SMV-G5H. The phyogenetic analyses reveal that SMV-G5H is most closely related to SMV-G5, and support that SMV-G5H might be derived from SMV-G5 by recombination rather than mutation.

Systemic acquired resistance is a form of inducible resistance that is triggered in systemic healthy tissues of local-infected plants. Several candidate signaling molecules emerged in the past two years, including the methylated derivatives of well-known defense hormones salicylic acid (SA) and jasmonic acid (JA). In our present study, the symptom on Cucumber mosaic virus (CMV) infected Arabidopsis leaves in 0.1 mM SA or 0.06 mM JA pre-treated plants was lighter (less reactive oxygen species accumulation and less oxidative damages) than that of the control group. JA followed by SA (JA${\rightarrow}$SA) had the highest inhibitory efficiency to CMV replication, higher than JA and SA simultaneous co-pretreatment (JA+SA), and higher than a JA or a SA single pretreatment. The crosstalk between the two hormones was further investigated at the transcriptional levels of pathogenesis-related genes. The time-course measurement showed JA might play a more important role in the interaction between JA and SA.

A 42-year-old male patient with prolonged throat pain and discomfort, dry mouth, and general weakness and recently diagnosed with tonsillitis, pulmonary embolism, and venous thrombosis was admitted to the internal Korean medicine department. A sudden onset of diabetic ketoacidosis with hyperammonemia was diagnosed on the second day of treatment. During admission, the patient received insulin therapy, hydration, and traditional Korean medicine treatment, including herbal medicine. Subjective symptom change was evaluated daily and blood glucose level checked five times per day. At discharge, the patient's fasting and postprandial blood sugar levels were adequate. After an additional two weeks of herbal treatment, the symptoms were significantly ameliorated. Thus, having been admitted with dysregulated glucose metabolism leading to a hyperglycemic crisis after a series of inflammatory events, the patient showed symptomatic improvements and decreased blood glucose after 18 days of hospitalization and treatment.

전신 홍반 루푸스는 다양한 증상으로 발현되는 자가면역질환이다. 위장관 증상도 질환의 경과 중에 나타날 수 있으나, 장 가성 폐쇄로 처음 진단되는 경우는 소아에서 매우 드물다. 장 가성 폐쇄는 원발성 또는 속발성으로 장의 평활근이나 신경계에 이상이 있어 해부학적 원인 없이 장폐쇄의 증상과 징후가 나타나는 것이며, 장폐쇄로 인하여 수술을 하였다는 보고도 있다. 그러나 장 가성 폐쇄가 전신 홍반 루푸스에 속발한 경우 장간막 혈관의 폐쇄와 장괴사로 진행하기 전에 조기에 진단하고 치료하면 합병증을 예방하고 수술을 피할 수 있다. 저자들은 장 가성 폐쇄의 증상으로 내원한 13세 여아에서 전신 홍반 루푸스를 진단하여, 불필요한 수술을 피하고 조기에 치료한 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Arabidopsis infected with beet curly top virus (BCTV) has the systemic symptoms like stunting of Plant growth, curling of leaves and shoot tips, and callus induction. The regulation of sucrose metabolism by BCTV infection is essential for obtaining the energy source in the process of virus replication and symptom development. Sucrose metabolism-associated gene expression and biochemical enzyme activity were analyzed with the rossette leaves and inflorescencestems of BCTV infected Arabidopsis by the time course of 1, 7, 14, 21 day postinoculation. The expression of invertase and sucrose synthase genes ( encoding sucrose-cleaving enzymes )was increased and reversely the level of Atkin10a ( sucrose non-fermenting gene ) was decreased, resulting by semi-quantitative reverse transcription polymerase chain reaction. The biochemical analysis of invertase and sucrose synthase activity was performed. The activity of neutral invertase in the inflorescence stems was elevated remarkably. The photosynthetic response in the source of sucrose metabolism was consistent with the down-regulation of ribulose 1,5 bisphosphate carboxylase gene, and lower activity than mock-inoculated plants. The levels of genes pertaining to the cell cycle, hormone, and biotic stress-related pathway showed an increase or a decrease dependent on viral symptoms. Therefore, sucrose sensing by BCTV infection can regulate the expression of sucrose metabolism-related key enzymes such as invertase and Atkin10a, and these gene products might influence to symptom development.
