Objectives : The purpose of this study is to explore research trends in gold implantation therapy performed on the animal and human body, through a review of clinical studies focused on gold thread, gold needle and gold bead. Methods : Medical databases, including Pubmed, CENTRAL, MEDLINE, EMBASE, RISS4u, KISTI, OASIS and KTKP, were searched for relevant articles published from their launch to December 31, 2015 using the key word 'gold' with '$thread^*$', '$needle^*$', '$acupuncture^*$', '$wire^*$', '$bead^*$', '$embed^*$', '$implant^*$', or '$insert^*$'. The results were classified into in vivo studies, clinical trials and clinical reports. Analysis of the results was conducted in several research areas, from the identity of studies such as nationality and published year, to the gold preparations-features and implanted locations and to the outcomes that reflect the clinically favorable or adverse effect of gold implantation therapy. Results : A total of 30 studies including 11 in vivo studies, 4 clinical trials and 15 case reports, were found in the search. We observed certain research trends according to the research time, nationality and target indication of the studies. The studies primarily revealed a chronic local inflammatory response which could be a useful mechanism for pain-relief in musculoskeletal diseases and facial rejuvenation. Researches concerning long-term reactions or adverse effects were rare. Conclusion : The results show that the efforts to discover the level of clinical efficacy of gold implantation therapy were steady and worldwide. However, further researches on the longterm effect, and more importantly, the safety of gold implantation therapy are required.

Background: To explore the relationship between persistent post-radiotherapy pain and locoregional recurrence in head and neck cancer patients. Methods: Five year retrospective data was reviewed of 86 patients of head and neck cancer treated with radiotherapy who continued to have pain at 6 weeks after completion of treatment. At follow-up after 3 months, these patients were stratified into: Group A (n = 39) constituted of patients whose pain subsided and Group B (n = 47) were patients who continued to have persistent pain. Results: At median follow-up time of 25 months (range: 8-47), one patient (2.6%) and 18 (38.3%) patients in group A and group B had locoregional recurrence respectively (P < 0.0001). Furthermore, group B patients had higher mean pain score levels as compared to group A (P = 0.03). Patients in whom pain subsided within 3 months had statistically much greater disease-free survival in comparison to those with persistent pain (P < 0.0001). Conclusions: Pain in head and neck cancer is an important symptom and should be considered a poor prognostic factor. In the current study, the majority of the patients with persistent pain had recurrent disease as compared to those in whom pain subsided within 3 months of post-treatment. It is suggested that patients with persistent pain need more intense follow-up and should be investigated thoroughly to detect recurrence at an early stage to provide a better quality of life.

Restenosis remains a major limitation of percutaneous coronary interventions. Numerous studios including pharmacological approaches and new devices failed to reduce the restenosis rate except coronary stenting. Since the results of $BENESTENT^{1)}\;and\;STRESS^{2)}$ studies came out, coronary stenting has been the most popular interventional strategy in the various kinds of coronary stenotic lesions, although the efficacy of stenting was shown only in the discrete lesion of the large coronary artery. The widespread use of coronary stenting has improved the early and late outcomes after coronary intervention, but it has also led to a new and serious problem, e.g., in-stent restenosis. Intravascular radiation for prevention of restenosis is a new technology in the field of percutaneous coronary intervention. Recent animal experiments and human trials have demonstrated that local irradiation, in conjunction with coronary interventions, substantially diminished the rate of restenosis. This paper reviews basic radiation biology of intracoronary radiation and its role in the inhibition of restenosis. The current status of intracoronary radiation therapy using Re-188 liquid balloon is also discussed.

Objective: To compare black rice (Oryza sativa L) extract with three different staining methods for human sperm head assessment. Methods: Semen samples were collected from 34 volunteers. Four smears of each ejaculate were prepared for staining using the rapid Papanicolaou (PAP) stain, SpermBlue, DipQuick, and black rice extract. The percentage of defective sperm heads (mean${\pm}$standard deviation) was compared. Results: Black glutinous rice extract, a natural dye, was used instead of hematoxylin to stain the nuclei of the sperm heads. The percentage of defective sperm heads showed a significant difference between black rice extract and DipQuick (p= 0.000). In contrast, black rice extract and rapid PAP showed no statistically significant difference (p= 0.974). A strong correlation (r = 0.761) was found between the findings obtained using rapid PAP and black rice extract. In contrast, a weak correlation (r = 0.248) was obtained between DipQuick and black rice extract for the percentage of defective sperm heads. Conclusion: The results showed good agreement and a strong correlation between the rapid PAP and black rice extract stains. The advantages of black rice extract as a novel substitute for hematoxylin for nuclear staining include ease of preparation, local availability, and favorable nuclear staining properties. Further studies could also focus on comparing staining techniques in clinical samples.

Despite the remarkable advancements of the modern medicine, the traditional system of medicine (TSM) still serves as a potential primary health care modality in the in low- and middle-income countries. The recent reports suggest that there is a renewed interest has been observed towards TSM in the developed countries too, because of the adverse side-effect of modern medicines. Medicinal plants have been widely serving as a rich source of therapeutic agent. Ethiopia is one of the most reserves rich countries in the world. It is renowned for well-diversified and natural resources in terms of its unique flora and fauna. Ethiopian deep-rooted tradition and culture largely depends on the usage of plants for their religious ceremonies, impressive festivals, traditional medicinal uses and other basic necessities. The present scrutiny is an attempt to understand the omnipotent nature of an Ethiopian Ethnomedicinal plant called Tinjute [vernacular name (local native language, Amharic); Otostegia integrifolia]. There are several studies suggest that Tinjute can be used as a natural medicine or health-promoting agents for various disorders and ailments. Nevertheless, in Ethiopia, it is renowned as an insect repellent to drive-away insect vector of diseases, particularly mosquitoes in the early evening. However, there are many more issues and challenges which must be urgently addressed to scientifically formulate various potent, efficacious, safe and highly selective phytotherapeutic agents and insects' repellent from the Tinjute plant in the near future.

The early glottic cancers are traditionally treated by radiotherapy or endoscopic surgery. The excellent effectiveness of both treatment modalities for local control, larynx preservation, and disease specific death is similar. Therefore, functional voice outcome after treatment is one of the most important factors in the choice of treatment for early glottic cancer. To assess the functional outcomes and compare the voice quality in patients with early glottic cancer treated with curative intent with radiotherapy or laser cordectomy, we performed literature review. Most studies showed that the voice quality after radiation therapy is slightly better than that after laser cordectomy. Subanalysis according to types of laser cordectomy, however, indicates that voice quality depends on type of laser cordectomy. Especially, type I or type II laser cordectomy might be superior to other types of laser cordectomy and radiation therapy. We conclude that the laser cordectomy is a good surgical alternative for properly selected early glottic cancer including professional voice users.

Background: Alzheimer's dementia is the most common dementia. However, recently, choline alfoscerate is prescribed for treating Alzheimer's dementia, although it is not a treatment for this disease. Purpose: To analyze the prescription patterns of choline alfoscerate as a dementia treatment for patients with Alzheimer's disease and to analyze, as well as the factors affecting choline alfoscerate prescription. Method: The 2016 HIRA-NPS data was used in this study. The code of Alzheimer's dementia is F00 in the ICD-10 disease classification code. We analyzed the demographic, clinical, and regional characteristics associated with donepezil, rivastigmine, galantamine, memantine, and choline alfoscerate prescriptions. All statistical and data analyse were conducted by SAS 9.4 and Excel. Results: For patients with Alzheimer's disease, choline alfoscerate was the second most prescribed after donepezil. Analysis results showed that choline alfoscerate was more likely to be prescribed to men than to women, and more likely to be prescribed by local health centers than by medical institutions. Moreover, choline alfoscerate was highly likely to be prescribed at neurosurgical departments, among medical departments. Conclusions: This study confirmed that choline alfoscerate was prescribed considerably for patients with Alzheimer's dementia. Further studies valuating its clinical validity should be performed to clarify whether choline alfoscerate prescription is appropriate for treating Alzheimer's dementia.

In molecular imaging studies via magnetic resonance imaging, in vivo cell tracking is an important issue for the observation of cell therapy or disease behavior. High resolution imaging and longitudinal study are necessary to track the cell movement. Since the field inhomogeneity extends over several voxels, we have performed the numerical analysis using the sub-voxel method dividing a voxel of MR image into several elements and the information about the field inhomogeneity distribution around the micro-beads. We imbedded ferrite-composite micro-beads with the size of $20-150{\mu}m$ in the subject substituted for cells to induce local field distortion. In the phantom imaging with the isotropic voxel size of $200{\mu}m^3$, we could confirm the feasibility of sub-voxel tracking in a 3.0 T MRI.
