  • Objective: The purpose of this study was to develop a standard tool for pattern identification of radiation pneumonitis. Methods: Textbooks, published studies, and references with comments about patterns were reviewed. Through the Delphi method, we determined pattern identifications based on advice from a committee of experts composed of 13 Korean respiratory internal medicine professors. Results: Using the Delphi method, four pattern identifications were chosen: Qi Deficiency (氣虛), Yin Deficiency (陰虛), Heat Toxin (熱毒), and Phlegm Dampness (痰濕). The tool was developed in a question-and-answer format with 35 questions. Conclusions: A pattern identification tool that can discriminate the patterns of radiation pneumonitis for standardized diagnosis was developed through expert consultation. Further study of its validity and reliability is necessary.

  • Background: Traditionally, interferon-${\gamma}$ (IFN-${\gamma}$) was regarded as a pro-inflammatory cytokine, however, recent reports suggested role of IFN-${\gamma}$ in immune tolerance. In our previous report, we could induce tolerance to male antigen (HY) just by male islet transplantation in wild type C57BL/6 mice without any immunological intervention. We tried to investigate the influence of IFN-${\gamma}$ deficiency on tolerance induction by male islet transplantation. Methods: To examine the immunogenicity of male tissue in the absence of IFN-${\gamma}$, we transplanted male IFN-${\gamma}$ knock-out (KO) skin to female IFN-${\gamma}$ KO mice. Next, we analyzed male IFN-${\gamma}$ KO islet to streptozotocin-induced diabetic female IFN-${\gamma}$ KO mice. And, we checked the functionality of grafted islet by graft removal and insulin staining. Results: As our previous results in wild type C57BL/6 mice, female IFN-${\gamma}$ KO mice rejected male IFN-${\gamma}$ KO skin within 29 days, and did not reject male IFN-${\gamma}$ KO islet. The maintenance of normal blood glucose level was dependent on the presence of grafted male islet. And the male islet recipient did not reject 2nd challenge of male islet graft also. Conclusion: Deficiency of IFN-${\gamma}$ does not have influence on the result of male skin graft and male islet transplantation. Conclusively, male islet transplantation induced T cell tolerance is not dependent on the presence of IFN-${\gamma}$.

  • Insects mount a robust innate immune response against a wide array of microbial pathogens. The hallmark of the Drosophila humoral immune response is the rapid production of anti-microbial peptides in the fat body and their release into the circulation. Two recognition and signaling cascades regulate expression of these antimicrobial peptide genes. The Toll pathway is activated by fungal and many Gram-positive bacterial infections, whereas the immune deficiency (IMD) pathway responds to Gram-negative bacteria. Recent work has shown that the intensity and duration of the Drosophila immune response is tightly regulated. As in mammals, hyperactivated immune responses are detrimental, and the proper down-modulation of immunity is critical for protective immunity and health. In order to keep the immune response properly modulated, the Toll and IMD pathways are controlled at multiple levels by a series of negative regulators. In this review, we focus on recent advances identifying and characterizing the negative regulators of these pathways.

  • Objective : Hyperhidrosis is a condition characterized by excessive sweating. Some studies suggest that hyperhidrosis is associated with autonomic nervous system dysfunction. Hyperhidrosis is often accompanied by hypersensitivity, tension, irritability, heat flashes, fatigue, etc. This study was designed to evaluate the correlation between Oriental Medicine diagnosis and the autonomic nervous system function in patients with hyperhidrosis using Heart Rate Variability (HRV) analysis. Methods : 23 palmar and plantar hyperhidrosis patients and 10 systemic hyperhidrosis patients were recruited and evaluated by Oriental Medicine diagnostic questionnaire and HRV analysis. The Oriental Medicine diagnostic questionnaire used a three-dimensional diagnosis that classified patients into Cold or Heat Syndrome, Yin or Yang Syndrome, and Deficiency or Excess Syndrome. Measured indices of HRV used the frequency domain analysis(i.e. TP, VLF, LF, HF and LF/HF ratio). Also, measure indices of HRV adjusted for aging effects were evaluated. Results : Cold/Heat Syndrome was not associated with hyperhidrosis prevalence nor the HRV analysis in hyperhidrosis patients. The Yang Syndrome group(78.8%) was more strongly correlated than the Yin Syndrome group(21.2%), and character of Yang was correlated with the adjusted TP and adjusted LF. The LF/HF ratio in the Excess Syndrome group was significantly higher than the LF/HF ratio in the Deficiency Syndrome group. Conclusion : Hyperhidrosis was not associated with the Cold/Heat Syndrome, but was found to be closely associated with the Yang Syndrome. The LF/HF ratio was significantly higher in the Excess Syndrome group than in the Deficiency Syndrome group in hyperhidrosis patients.

  • Pi(Spleen, 脾) corresponds to central earth and is called as the basis of acquired essence as it has the function of transforting and transforming the nutrients, keeping the blood circulating, and nourishing the muscle and limbs. Recently many studies to research the nature and deficiency of Pi are actively carried out. Especially functional deficiency of Pi(脾虛證) which occupies 60 to 70% or 88% in miscell aneous disease is divided into deficiency of Qi(脾氣虛), Yang(脾陽許), and Yin(脾陰虛), and tought to be positive when three or more such symptoms as anorexia, abdominal distension, loose bowels, pale face and weakness are present. Investigating the resent studies on the nature of the deficiency of Pi shows that Pi has the function of digestive system and also should be considered as functional unit of mult system related immune, metabolic, hematic, muscular, rnddocrine and nervus system. Various experiments as ptyaline activity test and xylose absorption test are used as an indication to deficiency of Pi and would be helpful to understand its nature. As deficiency of Pi appears in many disease and has various manifestations, further studies to diagnose the symptom of Pi using various experiments and oriental medical diagnostic method should be ensued.

  • The purpose of this paper is to review the literature of AIDS/HIV (acquired immune deficiency syndrome/human immunodeficiency virus) and to introduce physical therapy of the AIDS client. It was first reported that five young homosexual men, in 1981 in Los Angeles, died of pneumonia caused by pneumocystis carinii - called "pest of twentieth century". AIDS was implied a fatal breakdown of the functioning of the normal human immune system. The major routes of transmission has occurred via l)sexual contact between men, 2)heterosexual intercourse, 3)contaminated blood and blood products, and 4)intrauterine or pre-natal infection from mothers. AIDS clients who may require physical therapy for a wide range of problems due to respiratory, neurological, musculoskeletal and painful syndromes as well as general decline in fitness and function. AIDS is growing rapidly in our contury as well as all over the world. Therefore, physical therapist has to correct his understandings of AIDS in order to protect himself and to give proper physical therapy to the AIDS clients.

  • Human Immune Deficiency Virus (or simply HIV) induces a persistent infection that leads to AIDS causing death in almost every infected individual. As HIV affects the immune system directly by attacking the CD4+ T cells, to exterminate the infection, the natural immune system produces virus-specific cytotoxic T lymphocytes(CTLs) that kills the infected CD4+ T cells. The reduced CD4+ T cell count produce reduced amount of cytokines to stimulate the production of CTLs to fight the invaders that weakens the body immunity succeeding to AIDS. In this paper, we introduce a mathematical model with discrete time-delay to represent this cell dynamics between CD4+ T cells and the CTLs under HIV infection. A modified functional form has been considered to describe the infection mechanism. Characteristics of the system are studied through mathematical analysis. Numerical simulations are carried out to illustrate the analytical findings.

  • Objectives In this study, we divided Korean asthma patients into excess syndrome or deficiency syndrome groups according to clinical phenotype. Genetic analysis was conducted to investigate the association of exonic SNPs in the CD46 gene polymorphism with the clinical phenotype based on the differentiation syndrome of the bronchial asthma patients.Methods There were 95 healthy patients (control group) and 53 asthma patients. (The deficiency syndrome group included 24 and the excess syndrome group 29). We searched the exonic areas of the CD46 gene in the NCBI website SNPs with <0.01 minor allele frequency (MAF) and <0.01 heterozygosity. We finally selected two SNPs: rs138843816, Ser13Phe and rs7144, 3’-UTR. Hardy-Weinberg equilibrium was calculated using SNPStats.Results There were significant differences in the codominant 1 model and the dominant model between the healthy group and the asthma group. There were significant differences between deficiency syndrome group and the excess syndrome group in the genotype frequencies and in the codominant 1 model, the dominant model, and the log-additive model. The allele frequency of rs7144C showed a significant difference between the deficiency syndrome group and the excess syndrome group. Two-SNP haplotype analysis showed a significant difference in frequency in the deficiency syndrome group and in the excess syndrome group. There were significant differences between the healthy group and the excess syndrome group in the codominant 1 model, the dominant model, and the log-additive model. The frequency of the rs7144 C allele exhibited a significant difference in the demonstration. SNP haplotype analysis between the healthy group and the excess syndrome group showed a significant difference in the frequency of the CT haplotype and the CC haplotype.Conclusions The results indicate that two CD46 SNPs (rs138843816, Ser13Phe and rs7144, 3′–UTR) might be associated with the symptomatic excess syndrome in Korean asthma patients.
