  • This study was performed to investigate the effect of promoting gastrointestinal function and inhibiting of decreasing body temperature of ginger extract(Zingiber officinale) in rats. In order to elucidate the gastrointestinal function and inhibiting effect of body temperature of native ginger and improved ginger, water extracts of ginger were orally administrated into rats. The results are as follows: The gastrointestinal transit time was significantly decreased in native ginger(7.66hrs) and improved ginger(7.72hrs) extract administrated groups compare to control group(8.44hrs). The mean red faecal weight was increased in native ginger(30.6%) and improved ginger(31.1%) extract administrated groups compare to control group(24.9%) for 24hrs. Inhibiting effect of decreasing body temperature induced by serotonin was increased in native ginger($1.116^{\circ}C$) and improved ginger($1.416^{\circ}C$) extract administrated groups compare to positive control group($0.384^{\circ}C$) during 40 minutes. Gastrin and CGRP immunoreactive density was more strongly expressed in native ginger and improved ginger extract administrated groups compare to control group. Serotonin immunoreactive density was more weakly expressed in native ginger and improved ginger extract administrated groups compare to control group. These results suggest that ginger extracts may enhance physiological activity such as gastrointestinal motility, protection of mucosa and gastric acid secretion in gastrointestinal tracts, and inhibits decreasing body temperature

  • The vascular endothelial growth factor (VEGF), or VEGF-A, is intimately involved in both physiological and pathological forms of angiogenesis. VEGF-A is now recognized as the founding member of a family of growth factors that has expanded to include VEGF-B, VEGF-C, VEGF-D, VEGF-E, and placental growth factor (PIGF). This family of cytokines binds differentially to at least three receptor tyrosine kinases, however, the extent to which family members other than VEGF-A contribute to physiological and pathological angiogenesis remains unclear. Issues that are of relevance include uncertainty regarding the consequences of signaling through VEGF - RI in particular, and the ability of some family members to heterodimerize, leading to the possibility ofheterodimeric receptor complexes. Structural characterization is one approach that can be used to address these issues, however, the vast majority of previous structure-function studies have only focused on VEGF-A. While these studies may provide some clues regarding the structural basis of the interaction of other family members with their receptors, studies using the ligands themselves are clearly required if highly specific interactions are to be revealed. With the recent progress toward refolding and purifying substantial' quantities of other VEGF family members, such structural studies are now possible. Here, these ~ssues are addressed with a particular emphasis on VEGF-B and its receptors.

  • Polydnavirus genome is segmented and dispersed on host wasp chromosome. After replication, the segments form double- stranded circular DNAs and embedded in viral coat proteins. These viral particles are delivered into a parasitized host along with parasitoid eggs. A serine-rich protein (SRP) is predicted in a polydnavirus, Cotesia plutellae bracovirus (CpBV), genome in its segment no. 33 (CpBV-S33), creating CpBV-SRP1. This study explored its expression and physiological function in the diamondback moth, Plutella xylostella, larvae parasitized by C. plutellae. CpBV-SRP1 encodes 122 amino acids with 26 serines and several predicted phosphorylation sites. It is persistently expressed in all tested tissues of parasitized P. xylostella including hemocyte, fat body, and gut. Its physiological function was analyzed by injecting CpBV-S33 and inducing its expression in nonparasitized P. xylostella by a technique called SERI (segment expression and RNA interference). The expression of CpBV-SRP1 significantly impaired the spreading behavior and total cell count of hemocytes of treated larvae. Subsequent RNA interference of CpBV-SRP1 rescued the immunosuppressive response. This study reports the persistent expression of CpBV-SRP1 in a parasitized host and its parasitic role in suppressing the host immune response by altering hemocyte behavior and survival.

  • Objective & Method : We investigated the identity of tri-energizer, which was originally described in Huang Di Nei Jing and claimed by traditional scholars, and drew the following conclusions. Result & Conclusion : According to Huang Di Nei Jing tri-energizer is one of the six hollow-organs and is called hollow organs for digestion and elimination, water guffer organ, or solitary hollow organ. It is believed that tri-energizer is regarded as the existing entity based on following several different sources; it functions as the course of channels, regulates wind and link and physiological function-especially intrinsic function of upper, middle, lower internal organs. It also controls syndromes and dysfunction of an illness, the surface of the body, and the cracked surface of the skin. Finally, bold and timidity depend on the tri-energizer. Experts determined the true nature of tri-energizer types. Experts include: Yu Tuan from the Ming dynasty, Tang Jong Hai and Ye Lin from the Qing dynasty, and Zhang Xi Chun from the Zhunghua Minguo period. These experts' claims are based on shape and forms of tri-energizer. Our examinations of anatomical and physiological basis on tri-energizers showed that, in a narrow sense, tri-energizer indicates visceral and parietal peritoneum and omentum surrounding the internal organs, and in a broad sense, indicates the overall membrane wrapping around the whole internal organs including five visceral organs and six hollow organs.

  • Purpose: The purpose of this study was to determine factors related to regular walking exercise in the elderly using KNHNES data. Method: The study subjects, a total of 1437 adults over age 65, were classified into two groups based on their type of walking exercise: regular walking exercise group or irregular walking exercise group. The study variables were measured using scale physiological function, mental health status, chronic disease and quality of life. Results: The data was analyzed by $x^2$-test, t-test, and logistic regression using the SPSS 18.0 program. The factors related to regular walking exercise were male (OR=0.628, 95%CI=0.503-0.783), subjective health state (OR=0.832, 95%CI=0.751-0.921), thoughts of suicide (OR=0.753, 95%CI=0.586-0.967), hypoHDL-cholesterolemia (OR=0.742, 95%CI=0.591-0.930), and stroke (OR=0.604, 95%CI=0.366-0.997). Conclusion: The findings indicate that regular walking exercise in the elderly is related to physiological function, mental health status, and chronic disease. Therefore, providing for the education and awareness of health promotion for the elderly will may improve the quality of life in old age.

  • The aim of study is to contribute to this knowledge-base by investigating the respiratory function, the metabolic rate and the difference of physiological responses un-der low water temperature ($20^{\circ}C{\rightarrow}15^{\circ}C$) stress be-tween diploid and triploid far eastern catfish, Silurus asotus. During the 48 hrs of water temperature stress exposure time, the respiratory frequencies, $CO_2$ and ${NH_4}^+$ concentrations of diploid had higher values than those of triploid (p<0.05). However, pH of triploid was higher than those of diploid (p<0.05), and oxygen consumption rate was not different between diploid and triploid (p>0.05). The level of plasma cortisol and plasma glucose of triploid was lower than those of the diploid (p<0.05). However, in case of lactic acid, there were not significant between triploid and diploid (p>0.05). These results suggest that diploid was more sensitive for low water temperature stress response than triploid in this species.

  • Thick films of carbon fiber were prepared by a heating element of plan shape made in Darin co., We have investigated surface morphology of the specimen depending on heat-treatment temperatures. Scanning electron microscope(SEM) image of carbon fiber thick films of the specimen heat treated shows a grain growth at $1200^{\circ}C$ and becomes a poly-crystallization at $1350^{\circ}C$. The variation of resistivity at the thermally annealed specimen above $600^{\circ}C$ depends on type of the substrates. It may be due to a variation of film thickness and a difference of interfacial phenomena. A heating element of features was affected significantly by skin blood and quantity of heat of the body physiological function. After radiation of farinfrared for plate heating element, the function of biometric physiological is considered of skin blood flow and calorie which greatly affects on individuals. Electromagnetic wave was not influence on the body.

  • We investigated the structure-activity relationships on use of multi-layer neural networks. The relationships are techniques required in developments of medicines. Since many kinds of observations might be adopted on the techniques, we discussed some points between the observations and the properties of multi-layer neural networks. In the structure-activity relationships, an important property is not that standard deviations are nearly equal to zero for observed physiological activity, but prediction ability for unknown medicines. Since we adopted non-linear approximation, the function to represent the activity can be defined by observations; therefore, we believe that the standard deviations have not significance. The function was examined by "leave-one-out" method, which was originally introduced for the multi-regression analysis. In the linear approximation, the examination is significance, however, we believe that the method is inappropriate in case of nonlinear fitting as neural networks; therefore, we derived a new index fer the relationships from the differential of information propagation in the neural network. By using the index, we discussed physiological activity of an anti-cancer medicine, Mitomycine derivatives. The neuro-computing suggests that there is no direction to extend the anti-cancer activity of Mitomycine, which is close to the trend of anticancer developing.

  • This study addresses the physiological functions of the Ran-binding protein homolog NbRanBP1 in Nicotiana benthamiana. Virus-induced gene silencing (VIGS) of NbRanBP1 caused stunted growth, leaf yellowing, and abnormal leaf morphology. The NbRanBP1 gene was constitutively expressed in diverse tissues and an NbRanBP1:GFP fusion protein was primarily localized to the nuclear rim and the cytosol. BiFC analysis revealed in vivo interaction between NbRanBP1 and NbRan1 in the nuclear envelope and the cytosol. Depletion of NbRanBP1 or NbRan1 reduced nuclear accumulation of a NbBTF3:GFP marker protein. In the later stages of development, NbRanBP1 VIGS plants showed stress responses such as reduced mitochondrial membrane potential, excessive production of reactive oxygen species, and induction of defense-related genes. The molecular role of RanBP1 in plants is discussed in comparison with RanBP1 function in yeast and mammals.

  • When full denture is being fabricated, pronounciation, recovery of aesthetics of function and mastificatory function should be satisfies for patients. To satisfy for the function of denture, following is the difference between this new way of fabricating and formerly one of it. 1. The size of fabricating tooth which is harmony of original oral structure for patients is deaded by manufacturing labial index and artificial tongue. 2. By the use of artificial tongue and labial index, the arranges of artificial tooth is to become harmony of oral structure. 3. Formation of gingival decided functional impression which is used by impression paste, is harmony of oral structure. Therefore, this full denture can be satisfied with pronouncing oral function of recovery of aesthetics as well as mastificatory through physiological movement of oral tissue not disturbed with anything but cooperated drastically. In manufacturing of this full denture, both dentist and dental technician under cooperation need to proceed the work on the base of importance of communication.
