Objectives The purpose of this study is to understand the intention expressed as Jeubjeubhanchul(濈濈汗出) unlike the aspect of perspiration in 『Sanghanlun(傷寒論)』 and 『Donguibogam(東醫寶鑑)』. Methods We examined Sibjo-tang(十棗湯) and the aspect of perspiration focusing on the Chip(漐) and Jeub(濈) in 『Sanghanlun(傷寒論)』, 『Donguibogam(東醫寶鑑)』, and 『Donguisusebowon(東醫壽世保元)』. Moreover, we examined the connection between the quoted purpose of Sibjo-tang and the aspect of perspiration. Results and Conclusion 1. When Leejema quoted Sibjo-tang to explain the Chestbind disease(結胸) of the Soyang pattern, he used Jeubjeubhanchul (濈濈汗出) instead of Chipchiphanchul(漐漐汗出). 2. About the aspect of perspiration in 『Sanghanlun』 and 『Donguibogam』, the Chip(漐) is used in a situation when the disease progressed from Pyo(表) to Li(裏) and Taeyang-byeong(太陽病) to Yangmyung-byeong(陽明病), and it is expression of physiological perspiration. The Jeub(濈) is used in a situation related to interior(內), Li(裏), and Yangmyung-byeong. 3. Leejema understood Sibjo-tang in relation to the Chestbind disease of the Soyang pattern caused by aggravation of Liyeol (裏熱). Therefore, Leejema used the Jeub(濈) related to interior, Li and Yangmyung-byeong, and it is expression of perspiration caused by aggravation of Liyeol in the Soyang pattern. 4. At first time, Leejema mentioned perspiration and short of breath(短氣) in the symptoms of Sibjo-tang, but he mentioned dry vomiting(乾嘔) and short of breath in 『Sinchukbon(辛丑本)』. Thus, his perspective of perspiration related to Sibjo-tang was appeared in 『Gabobon(甲午本)』, and he paid attention to perspiraion as a major symptom of the Chestbind disease in the early. After clinical experience was built up, It was not that important as the past.

Objectives : The purpose of this study was to evaluate effects of taping therapy on recovery of behavioral symptoms and neural excitability of the lumbar spinal cord in rat model for ankle sprain. Methods : Adult Sprague-Dawley rats was used and divided into 3 experimental groups: normal group(n=6), ankle sprain(n=6), and ankle sprain with taping treatment(n=6). In order to induce ankle sprain the right ankle joint was injured with 4~5 repetitive over-flexions and over-extensions manually. The severity of joint pain was evaluated by measuring foot weight bearing force ratio(FWBRF) of the hind limb and the injury-induced edema formation by diameter of the joint following ankle sprain. The changes of neural excitability in the lumbar spinal cord was tested by observation of cFos protein expression, a metabolic marker for neural excitation. Results : Severity of ankle injury induced in this experiment coincided with Grade 1 ankle sprain. Compared with ankle sprain group, ankle sprain＋taping showed a significant reductions of joint pain as well as of edema formation at the ankle joint following ankle sprain. There was significant upregulation of cFos-immunoreactive neurons in the lumbar spinal cord 24 hours after ankle sprain. In contrast, taping therapy resulted in significant inhibition of cFos-immunoreactive neurons in the lumbar spinal cord. Conclusions : Collectively, these results suggest that taping therapy may be an alternative therapeutic intervention for symptom recovery of the mild ankle sprain.

Tobacco mosaic virus(TMV) coat protein cDNA was transformed to Nicotiana tabacum cv. NC82 and the transgenic tobacco plants resistant to TMV infection were isolated in the next generation. The expression of TMV coat protein cDNA and genetic stability of the fifth generation of TMV resistant transgenic tobacco plants at the higher temperature were investigated. The TMV coat protein cDNA was amplified by genomic PCR in all the TMV resistant transgenic tobacco plants. The TMV coat protein expressed in the transgenic tobacco plants was detected at very low level by immunoblot hybridization. Even in tansgenic plants that showed the viral symptom only on very late sucker growth (delay type plants), the coat protein expression in the suckers was much less than that of susceptible tobacco infected with TMV. The TMV coat protein expressed in the transgenic tobacco plants was below 0.01% of total protein. Transcription and expression of the coat protein cDNA in delay type plants were observbed at high temperature (38$^{\circ}C$), and TMV replication was suppressed at both 28$^{\circ}C$ and 38$^{\circ}C$. This indicates that unlike the resistance conferred by 'N' gene. TMV resistance of transgenic tobacco plant won't break down at high temperature.

In this study, resistance responses were investigated during the interaction of Botrytis fabae with two faba bean cultivars expressing different levels of resistance against this pathogen, Nubaria (resistant) and Giza 40 (susceptible). Disease severity was assessed on leaves using a rating scale from 1 to 9. Accumulation levels of reactive oxygen species (ROS), lipid peroxidation and antioxidant enzymes (superoxide dismutase, catalase and ascorbate peroxidase) were measured in leaf tissues at different times of infection. The expression profiles of two pathogenesis-related proteins (PRPs) encoded by the genes PR-1 and ${\beta}$-1,3-glucanase were also investigated using reverse transcription RT-PCR analysis. The accumulation of these defense responses was induced significantly in both cultivars upon infection with B. fabae compared with un-inoculated controls. The resistant cultivar showed weaker necrotic symptom expression, less ROS accumulation, a lower rate of lipid peroxidation and higher activity of the enzymatic ROS scavenging system compared with susceptible cultivar. Interestingly, ROS accumulated rapidly in the resistant leaf tissues and peaked during the early stages of infection, whereas accumulation was stronger and more intense in the susceptible tissues in later stages. Moreover, the response of the resistant cultivar to infection was earlier and stronger, exhibiting high transcript accumulation of the PR genes. These results indicated that the induction of oxidant/antioxidant responses and the accumulation of PRPs are part of the faba bean defense mechanism against the necrotrophic fungus B. fabae with a different intensity and timing of induction, depending on the resistance levels.

Alternanthera mosaic virus (AltMV) is a member of the genus Potexvirus which has been known for less than twenty years, and has been detected in Australasia, Europe, North and South America, and Asia. The natural host range to date includes species in at least twenty-four taxonomically diverse plant families, with species in at least four other families known to be infected experimentally. AltMV has been shown to differ from Potato virus X (PVX), the type member of the genus Potexvirus, in a number of ways, including the subcellular localization of the Triple Gene Block 3 (TGB3) protein and apparent absence of interactions between TGB3 and TGB2. Differences between AltMV variants have allowed identification of viral determinants of pathogenicity, and identification of residues involved in interactions with host proteins. Infectious clones of AltMV differing significantly in symptom severity and efficiency of RNA silencing suppression have been produced, suitable either for high level protein expression (with efficient RNA silencing suppression) or for Virus-Induced Gene Silencing (VIGS; with weaker RNA silencing suppression), demonstrating a range of utility not available with most other plant viral vectors. The difference in silencing suppression efficiency was shown to be due to a single amino acid residue substitution in TGB1, and to differences in subcellular localization of TGB1 to the nucleus and nucleolus. The current state of knowledge of AltMV biology, including host range, strain differentiation, host interactions, and utility as a plant viral vector for both protein expression and VIGS are summarized.

Typical susceptible symptoms of the bacterial pustule disease caused by Xanthomonas axonopodis pv. glycines are pustule and chlorotic haloes that usually occur in leaves of Glycine max plants. The soybean genotype 'PI96188' showed an atypical response to all tested races X. axonopodis pv. glycines, accompanied with necrosis without chlorotic haloes on the underside of the necrotic symptoms. X. axonopodis pv. glycines 8ra grew to levels from 10 to 100 fold lower on PI96188 than on susceptible cultivar Jinjoo1, but 10-fold higher than on the resistant cultivar CNS. The chlorophyll content in PI96188 leaves remained unchanged until 12 days after bacterial infection. Ultrastructural observation showed that the infected leaf cells of PI96188 had intact normal chloroplasts compared to those of the susceptible cultivar Jinjoo1. Chloroplast degradation or the absence of chloroplasts in cells of the infected tissues was observed in Jinjoo1. Senescence-related ACS7 gene was significantly induced in PI96188 compared to those in Jinjoo1 at 2 days after inoculation. While photosynthesis-related rbcS gene showed the dramatic change in Jinjoo1, this gene was constitutively expressed in PI96188. However, expression of the defense-related genes, such as peroxidase and isoflavone synthase in the infected PI96188 leaves was similar to that in Jinjoo1. Together, these results suggest that the novel necrotic symptom in PI96188 is a kind of resistant response different from a typical hypersensitive response in the resistant genotypes.

Background and Objectives: Embryologically, mesodermal development is closely related to the development of various organs such as muscles, blood vessels, and hearts, which are the main organs that make up the body. However, treatment for mesoderm developmental disorders caused by congenital or acquired factors has so far relied on surgery and drug treatment for symptom relief, and more fundamentally, treatment for mesoderm developmental disorders is needed. Methods and Results: In our study, microRNA (miRNA), which plays an important role in the mesoderm development process, was identified and the developmental function was evaluated. miRNAs consist of small nucleotides, which act as transcription factors that bind to the 3' untranslated region and suppressed target gene expression. We constructed the human embryonic stem cell (hESC) knockout cell line and analyzed the function and characteristics of miR-5739, which plays an important role in mesoderm lineage. miR-5739 acts as a transcription factor targeting SMA, Brachyury T, Hand1, which controls muscle proliferation and differentiation, and KDR gene, which regulates vessel formation in vitro. In vivo results suggest a role in regulating muscle proliferation and differentiation. Gene ontology analysis confirmed that the miR-5739 is closely related to genes that regulate muscle and vessel proliferation and differentiation. Importantly, abnormal expression of miR-5739 was detected in somatic cells derived from patients with congenital muscle disease. Conclusions: Our study demonstrate that miR-5739 gene function significantly affects transcriptional circuits that regulate muscle and vascular differentiation during embryonic development.

The aim of this study was to characterize the interactions of rice and Burkholderia glumae, a causal agent of bacterial grain rot of rice, at molecular levels using whole genomic sequences and to identify genes important for pathogenicity and symptom development. To do these, we sequenced whole genome of the bacterium and constructed cosmid clone profiles. We generated pools of mutants using various transposons and determined mutation sites by sequencing rescued plasmids. We focused on studying toxoflavin biosynthetic genes, quorum sensing regulation, and Hrp type III protein secretion systems. We found that two possible operons consisting of five genes are involved in toxoflavin biosynthesis and their expression is regulated by quorum sensing and LysR-type regulator, ToxR. We have isolated the nn PAI of B. glumae and characterized by mutational analyses. The hrp cluster resembled most the putative Type III secretion systems of B. pseudomallei, which is the causative agent of melioidosis, a serious disease of man and animals. The Hrp PAI core region showed high similarity to that of Ralstonia solanacearum and Xanthomonas campestris, however some aspects were dissimilar.

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.
