  • In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional photon beam radiation during treatment. The relative biological effectiveness (RBE) is used for many biological, clinical endpoints among different radiation types and is the only convenient way to transfer the clinical experience in radiotherapy with photons to another type of radiation therapy. However, the RBE varies dependent on the energy of the beam, the fractionation, cell types, oxygenation status, and the biological endpoint studied. Thus this review describes the concerns about RBE related to particle beam to increase interests of the Korean radiation oncologists' society.

  • Peroxisome proliferator-activated receptor gamma (PPAR-${\gamma}$), a ligand-dependent nuclear transcription factor, has been found to widely exist in tumor tissues and plays an important role in affecting tumor cell growth. In this study, we investigated the effect of PPAR-${\gamma}$ on aspects of the cervical cancer malignant phenotype, such as cell proliferation and apoptosis. Cell growth assay, Western blotting, Annexin V and flow cytometry analysis consistently showed that treatment with troglitazone (TGZ, a PPAR-${\gamma}$ agonist) led to dose-dependent inhibition of cervical cancer cell growth through apoptosis, whereas T0070907 (another PPAR-${\gamma}$ antagonist) had no effect on Hela cell proliferation and apoptosis. Furthermore, we also detected the protein expression of p53, p21 and Mdm2 to explain the underlying mechanism of PPAR-${\gamma}$ on cellular apoptosis. Our work, finally, demonstrated the existence of the TGZ-PPAR-${\gamma}$-p53 signaling pathway to be a critical regulator of cell apoptosis. These results suggested that PPAR-${\gamma}$ may be a potential therapeutic target for cervical cancer.

  • Hadron therapy, such as carbon and helium ions, is increasingly coming to the fore for the treatment of cancers. Such hadron therapy has several advantages over conventional radiotherapy using photons and electrons physically and clinically. These advantages are due to the different physical and biological characteristics of heavy ions including high linear energy transfer and Bragg peak, which lead to the reduced exit dose, lower normal tissue complication probability and the increased relative biological effectiveness (RBE). Despite the promising prospects on the carbon ion radiation therapy, it is in dispute with which bio-mathematical models to calculate the carbon ion RBE. The two most widely used models are local effect model and microdosimetric kinetic model, which are actively utilized in Europe and Japan respectively. Such selection on the RBE model is a crucial issue in that the dose prescription for planning differs according to the models. In this study, we aim to (i) introduce the concept of RBE, (ii) clarify the determinants of RBE, and (iii) compare the existing RBE models for carbon ion therapy.

  • Purpose: This study was to identify the effects of laughing and music therapy on depression and the activities of the autonomic nervous system in the elderly with dementia. Methods: The participants were 61 seniors over 65 years old with dementia, admitted to nursing homes. Twenty of them received laughing therapy, 21 received music therapy and 18 were in the control group. A total of 59 patients' data were analyzed. Depression was measured by Cornell Scale for Depression in Dementia tool, and the activities of the autonomic nervous system by the heart rate variability measuring device. The data were analyzed by frequency and percentage, Chi-square test, t-test, ANOVA, and Tukey test. Results: The depression of the music therapy group was more significantly decreased than the laughing therapy group and the control group. The activities of the autonomic nervous system of the laughing therapy group were more significantly increased than the music therapy group. The magnitude of the activities of the autonomic nervous system of the laughing therapy group were more significantly increased than the music therapy group. Conclusion: This study showed that music therapy was more effective than laughing therapy for the decrease of depression. Laughing and music therapy were more effective than in the control group for increasing the activities of the para-sympathetic nervous system and decreasing the activities of the sympathetic nerve system.

  • Purpose: This study was conducted to ascertain the effectiveness of forest healing therapy by analyzing researches on forest healing therapy applied to Korean adults and to confirm that forest healing therapy can be used as a therapeutic intervention program for elderly nursing or rehabilitation nursing. Methods: We searched 972 research papers on forest therapy applied to Korean adults. We reviewed appropriate 25 research papers with experimental design among them in the final analysis. Results: Forest healing therapy had physiological and psychosocial effects. First of all, it showed physiological effects to reduce stress index such as heart rate variation. Forest therapy also improved melatonin level in blood of middle-aged women with menopause and increased alpha wave in electroencephalogram and decreased lipid level and superoxide dismutase in blood. Second, forest healing therapy showed psychosocial effects to reduce depression and to improve mental health. But the effects appeared differently depending on the implementing type, period of forest healing therapy, and the professionalism of therapists. Therefore, if forest healing therapy would be applied to nursing, it should be based on its key principle, in other words, its principle of action-interaction-response of forest healing therapy. Conclusion: The results of this study could be used to develop a forest healing program as an intervention of nursing.

  • Purpose: The purpose of this study was to examine the effect of music therapy on pain, depression in terminally-ill patients. Methods: The subjects for this study were collected from 44 patients who were admitted in F hospital, located in D city from July 1 to July 31 in 2008. The subjects were divided into two groups: 23 experimental group members and 21 control members. While the control group was not received any additional intervention, the experimental group was received music therapy intervention. Data analysis were performed by the chi-square test, t-test and ANCOVA with SPSS/WIN 12.0 Program. Results: The 1st hypothesis is, "the experimental group who received music therapy would have less pain score than the control group who did not receive music therapy", was rejected (F=2.33, p=.14). The 2nd hypothesis is, "the experimental group who received music therapy would have less depression score than the control group who did not receive music therapy", was supported (F=11.616, p=.001). These results demonstrated that music therapy to terminally patients was an effective method in decreasing depression. Conclusion: Based on the results of this study, Music therapy can be utilized as an effective nursing intervention for the terminally ill.
