  • Objectives : We search the contents about Bi disease in Huang Di Nei Jing(黃帝內經), to analyze the significance of Bi disease, etiopathogenisis and pathogenesis of Bi disease, treatment of Bi disease. Methods : We find that the key feature of Bi disease is joint pain induced by impatency of Qi and blood. Exterior and interior etiological factors are involved in, such as exogenous evil of cold and dampness, emotional disorders, intemperance of taking food, dysfunction of yingqi and weiqi, strong or weak constitution, etc. Results : The important pathogenesis are invaded by exogenous evil because of deficiency, disharmony of yingqi and weiqi and disharmony of five viscera. The key points of treatments are the individual concerned therapy and climate concerned therapy, selecting the acupoint according to the differentiation of symptoms and signs. Conclusions : The combined therapy should be used such as acupuncture and moxibustion, hot application of medicine, massage, Daoyin, outside apply, etc. These supply the theory foundation for etiological factor, pathogenesis, syndrome and treatment, and to direct the diagnosis and treatment of Bi disease later generations.

  • Exogenous putrescine of 0.5 mM or higher concentratons applied during a 16 h inductive dark period could elevate putrescine content in cotyledons of Pharbitis nil Choisy cv. Violet, a short-day plant, resulting in complete blocking of photoperiodic floral induction. Titers of putrescine, spermidine and spermine in the cotyledons were traced throughout a 16 h dark period. While non-induced cotyledons under continous light slightly increased levels of polyamines, induced tissue maintaiend its putrescine, spermidine and spermine levels as low as 66.4%, 60.9% and 84.9% of non-induced levels respecitvely. Endogenous polyamines kept at lower levels in the inductive dark period were found to upsurge by a night break treatment of 10 min light in the middle of the dark and consequently the inductive dark effect was canceled. Elevation of polyamine titers could also be induced by 100 $\mu$L/L ethylene treatment which completely suppressed floral induction. Compared to untreated cotyledons, ehtylene-treated tissues increased putrescine content by as much as 136.5% in 12 h and spermidine level by up to 130.1% in 8 h. Ethylene-treated cotyledons not only increased endogenous polyamine content but also liberate ethylene in the second half of the inductive dark period accumulating up to three to fourfold level supporting a hypothesis that ethylene-treated tissues are stimulated to produce ethylene which in turn accelerates polyamine biosynthesis in the tissues. It is postulated that substantially low polyamine titers in the inductive dark period would be one of the necessary factors controlling photoperiodic induction of flowering in Pharbitis nil and the inhibitory effects of night break and exogenous ethylene treatment may be atributed to their action to stimulate endogenous polyamine production.

  • This study has been carried out to investigate the cause and originative mechanism of vertigo by referring to 46 literatures. The results were as follows; 1. The 1st factors causing vertigo are exuberance of fire in the Liver (肝火偏亢). and ascending of Yang of Wind (風陽升動) resulting from thought excess (思慮太過) and melancholy (憂鬱). 2. The 2nd factors causing vertigo is a malnurtrient of the brain resulting from dispersion of the Liver function (肝血虛) and failure in ascending of the Clear Yang (淸陽不升) due to hemorrhage and so on. 3. The 3rd factors causing vertigo are failure in ascending to the Brain and deficiency of blood of the Liver (肝血虛) resulting from the injury of the essence of the Kidney (肝精虧損). 4. The 4th factors causing vertigo is a ascending of exogenous pathogenic factors (外邪) to the Brain on deficiency state. 5. The 1st factors causing vertigo are Stagnatum of clear Yang (淸陽不振) and pershing of Yang (亡陽) resulting from loss of water and damage of active thin body fluid (津氣虧損). 6. The obesity is beonged to excessiveness Symptom-Complex (實證) and the thin to deficiency Symptom-complex (虛證). 7. The vertigo is connective with the Live (肝), Spleen (脾) and the Kidney (腎), but among those, most intimative viscera is the Liver (肝).

  • The intestinal environment plays a critical role in maintaining swine health. Many factors such as diet, microbiota, and host intestinal immune response influence the intestinal environment. Intestinal alkaline phosphatase (IAP) is an important apical brush border enzyme that is influenced by these factors. IAP dephosphorylates bacterial lipopolysaccharides (LPS), unmethylated cytosine-guanosine dinucleotides, and flagellin, reducing bacterial toxicity and consequently regulating toll-like receptors (TLRs) activation and inflammation. It also desphosphorylates extracellular nucleotides such as uridine diphosphate and adenosine triphosphate, consequently reducing inflammation, modulating, and preserving the homeostasis of the intestinal microbiota. The apical localization of IAP on the epithelial surface reveals its role on LPS (from luminal bacteria) detoxification. As the expression of IAP is reported to be downregulated in piglets at weaning, LPS from commensal and pathogenic gram-negative bacteria could increase inflammatory processes by TLR-4 activation, increasing diarrhea events during this phase. Although some studies had reported potential IAP roles to promote gut health, investigations about exogenous IAP effects or feed additives modulating IAP expression and activity yet are necessary. However, we discussed in this paper that the critical assessment reported can suggest that exogenous IAP or feed additives that could increase its expression could show beneficial effects to reduce diarrhea events during the post weaning phase. Therefore, the main goals of this review are to discuss IAP's role in intestinal inflammatory processes and present feed additives used as growth promoters that may modulate IAP expression and activity to promote gut health in piglets.

  • This study aims to confirm which factors related to technology acceptance affect generation MZ's use of luxury fashion platforms. For this purpose, Internet self-efficacy and technology readiness were added as new exogenous and moderating variables using extended UTAUT. Then, performance expectancy, effort expectancy, social influence, and facilitating condition as a factor of UTAUT were set as mediating factors. Response data were collected through questionnaires for generation MZ with experience in using luxury fashion platforms, and a factor analysis, reliability analysis, correlation analysis, and path analysis were conducted using the SPSS and AMOS statistical programs. According to the results, the Internet self-efficacy of generation MZ significantly affected on performance expectancy, effort expectancy, social influence, and facilitating conditions on the luxury fashion platform. Moreover, performance expectancy and social influence had a significant effect on the use intention of luxury fashion platforms, but effort expectancy and facilitating condition did not have a significant effect on use intention and use behavior. Additionally, as the moderating effect of technology readiness affects only the relationship between social influence and behavioral intention, it was confirmed that social influence is an important variable with the characteristics of MZ consumers. Therefore, it is deemed necessary to recognize the importance of social influence when trying to use new technologies targeting generation MZ in the fashion industry.

  • Purpose: This study was done to develop a predictive model for quality of life of elderly residents in long-term care facilities (LTCF). The study was based on Brofenbrenner's ecological system theory and a literature review. Methods: Data were collected using a convenience sample of 205 elderly residents in 2 nursing homes located in D city and 1 nursing home located in K province. The exogenous variables were individual factors, family support, and facility environmental factors. The endogenous variables were self-esteem, accommodation adaptation and quality of life of elderly residents in LTCF. Collected data were analyzed through structural equation modeling using AMOS 20.0. Results: Eleven of the twelve hypotheses were supported, but the hypothesis that facility environment factors effect self-esteem was not supported. Quality of life of elderly residents in LTCF was explained first by facility environmental factors, followed by self-esteem, individual factors, accommodation adaptation, and family support with an explanatory power of 83.0%. Conclusion: To improve the quality of life of elderly residents in LTCF, the service and environment preparation provided by facilities is important, and it is necessary to provide emotional counseling to improve the self-esteem of these elders.
