The 8 kDa antigenic protein of Clonorchis sinensis was partially purified by ammonium sulfate precipitation and subsequently by a column chromatographic steps. The purified protein was separated into 7 and 8 kDa protein bands through SDS-tricine gel electrophoresis, while the protein was fecund to migrate to a 8 kDa band in 7.5-15% SDS-PAGE. The molecular weight of the antigen was estimated to be 110 kDa by Superose 6 HR 10/30 gel filtration. The purified antigen strongly reacted with the human sera of clonorchiasis. The hyperimmune sera of BALB/c mice immunized against the 8 kDa protein were reacted with both the crude extract and the excretory-secretory product of adult worms, but not with the metacercarial extract. Immunohistochemical staining demonstrated that the protein was distributed to the tegument and subtegumental cells and also to the seminal receptacle. The present findings suggest that the 8 kDa protein is a partition of the multicomplek protein originating from various organs of adult C. sinenis, and that it is composed of several 7 and 8 kDa proteins.

While the threat from traditional communicable diseases have been decreasing non communicable chronic diseases are increasing due to the aging of population and change in life pattern of the people such as over intake of cholesterol and lack of physical exercise etc. On the other hand, since 1980s, AIDS is spreading rapidly throughout the globe and environmental pollution, accidents, addictive diseases such as drug abuse and alcoholism are becoming serious factors to hinder the health promotion of the people. In order to improve general public health and promote individual health status, existing program for communicable disease control by the government such as tuberculosis, leprosy, STD and acute communicable diseases should be effectively continued. In principle, effort should be placed on eradication of source of infection, reduction of communicability of source in infection, treatment of source of infection as well as increase of individual registance to the diseases through immunization and improvement of physical status. Since the pattern of illness is being shifted from communicable diseases to non communicable chronic diseases such as cancer, cerebral hemorrhage, heart disease and hypertention etc., special emphasis should be placed on the prevention and control of those adult diseases. Early detection of the patients, registration and treatment of patients and health education should be systematically developed for effective control of the diseases. In addition, program activities on MCH, nutrition, dentistry, mental health, environmental health, accident prevention. medical delivery system, health insurance. and all other health issues should be improved in order to achieve our goal of health promotion.

Background: Niemann-Pick disease type C (NPC) is caused by the mutation of NPC genes, which leads to the abnormal accumulation of unesterified cholesterol and glycolipids in lysosomes. This autosomal recessive disease is characterized by liver dysfunction, hepatosplenomegaly, and progressive neurodegeneration. Recently, the application of induced neural stem cells (iNSCs), converted from fibroblasts using specific transcription factors, to repair degenerated lesions has been considered a novel therapy. Objectives: The therapeutic effects on NPC by human iNSCs generated by our research group have not yet been studied in vivo; in this study, we investigate those effects. Methods: We used an NPC mouse model to efficiently evaluate the therapeutic effect of iNSCs, because neurodegeneration progress is rapid in NPC. In addition, application of human iNSCs from NPC patient-derived fibroblasts in an NPC model in vivo can give insight into the clinical usefulness of iNSC treatment. The iNSCs, generated from NPC patientderived fibroblasts using the SOX2 and HMGA2 reprogramming factors, were transplanted by intracerebral injection into NPC mice. Results: Transplantation of iNSCs showed positive results in survival and body weight change in vivo. Additionally, iNSC-treated mice showed improved learning and memory in behavior test results. Furthermore, through magnetic resonance imaging and histopathological assessments, we observed delayed neurodegeneration in NPC mouse brains. Conclusions: iNSCs converted from patient-derived fibroblasts can become another choice of treatment for neurodegenerative diseases such as NPC.

An increase in serum cholesterol is directly associated with high incidences of cardiovascular diseases (CVD) and atherosclerosis. Serum lipid profiles are highly dependent on dietary fatty acids and age. The purpose of this study was to examine the age-related effects of polyunsaturated/saturated fatty acid ratios and antioxidant supplementation under the control of the dietary peroxidizability index (PI) value on serum lipid profiles in rats. While the PI level of dietary fatty acids was controlled at 81.22, the P/S ratios of fatty acids were 0.38 and 4.81 (LP and HP). The diets were supplemented with a vitamin E 1000 mg/kg diet and a selenium 2.5 mg/kg diet (LPS and HPS). Female Sprague-Dawley rats ages 3 weeks (young) and 16 weeks (adult) were fed four different experimental diets for 4 weeks. The serum triglyceride concentration of LPS was significantly higher in young rats than in adult rats. The total-cholesterol concentration of LP and HPS were higher in young rats than in adult rats. The high-density lipoprotein-cholesterol (HDL-C) concentration of LP, LPS and HP was higher in adult rats than in young rats. The low-density lipoprotein-cholesterol (LDL-C) concentration was higher in young rats than in adult rats. T-C/HDL-C and LDL-C/HDL-C ratios were much higher in young rats than in adult rats. In conclusion, P/S ratios and antioxidant supplementation did not affect T-C/HDL-C and LDL-C/HDL-C ratios as risk factors of CVD in adult rats when we controlled the PI value in the diet Probably, the invisible and confounding effects of dietary PI value implicate the beneficial roles of dietary P/S ratios and antioxidants in CVD. Accordingly, controlling the dietary PI value may be advantageous to lower the risk of CVD in adult rats.

Purpose: The purpose of this study was to analyze the characteristics and effects of the forest therapy programs for adult patients. Methods: Six databases (PubMed, Cochrane library, CiNii, PsychoInFO, AGRICOL, EMBASE) and six domestic databases were systematically searched with language restrictions of Korean, English, and Japanese. The systematic review was based on the Preferred Reporting Items Systematic Reviews and Meta-Analysis (PRISMA) flow diagram. Results: Twenty five studies met the inclusion criteria. A systematic review identified adult patients classified as 1) disease of the circulatory system, 2) mental and behavioral disorders, 3) malignant neoplasms, 4) etc. (diabetes mellitus, chronic pain). This integrative review showed a positive effect of the forest therapy program for adult patients on physiological indices such as blood pressure, heart rate, heart rate variability, level of stress hormone, and natural killer cells as well as social·psychological indices such as the Profile of Mood States (POMS), anxiety, depression, and quality of life. Conclusion: The results of this study could be useful key principles in developing and applying the forest therapy programs in nursing intervention. Further research should be conducted to develop the forest therapy programs suitable for each patient group and measure its effectiveness.

Acute eosinophilic pneumonia is a severe and rapidly progressive lung disease that can cause fatal respiratory failure. Since this disease exhibits totally different clinical features to other eosinophilic lung diseases (ELD), it is not difficult to distinguish it among other ELDs. However, this can be similar to other diseases causing acute respiratory distress syndrome or severe community-acquired pneumonia, so the diagnosis can be delayed. The cause of this disease in the majority of patients is unknown, even though some cases may be caused by smoke, other patients inhaled dust or drugs. The diagnosis is established by bronchoalveolar lavage. Treatment with corticosteroids shows a rapid and dramatic positive response without recurrence.
