Objectives: To review and analyze clinical and preclinical evidence of effectiveness, safety, and underlying mechanisms of yokukansan (YKS), a herbal medicine, in alleviating aggression. Methods: Classical records on YKS were searched in the Korean Traditional Medicine Knowledge Database (KTMKD). By searching five electronic databases, prospective clinical studies and preclinical studies of YKS for alleviating aggression/agitation published up to March 30, 2021 were included. Results: Only two classical records on YKS were found from the KTMKD. A total of 11 clinical studies and 15 preclinical studies were found from the five electronic databases. Among 11 clinical studies, seven enrolled patients with dementia and four enrolled patients with other neuropsychiatric disorders. Most clinical studies reported significant improvement in one or more outcomes related to aggression in the YKS group after treatment. Among 15 preclinical studies, all studies except two reported a significant decrease in aggression/agitation-related behavior of YKS or yokukansankachimpihange. Suggested underlying mechanisms of YKS or yokukansankachimpihange for aggression/agitation in these studies included regulation of serotonin receptor, amelioration of abnormal glucocorticoid level related to the hypothalamic-pituitary-adrenal axis, regulation of orexin secretion, amelioration of degeneration in brain cells including glia cells, and suppression of excessive glutamatergic or dopaminergic activity. Conclusions: There were some clinical and preclinical evidence supporting the effectiveness and safety of YKS for alleviating aggression. Given that aggression is the most frequent and destructive symptoms of behavioral and psychological symptoms of dementia, applicability of YKS as a herbal medicine should be further investigated in future high-quality research.

Objectives: To overcome the limitations of randomized controlled trials, many other trials design is tested. The n-of-1 trial is a promising research method in the field of Korean medicine because of this methodology can examine the optimal treatment for each patient strictly. Therefore, we reviewed the status of N-of-1 studies on herbal medicine. Methods: A systematic literature review was conducted based on the pubmed database. The search term were 'N-of-1 Trial', 'Chinese Medicine', 'Herbal Medicine', 'Kampo'. There was no restriction in year. Results: Four clinical trials have been identified to demonstrate the effectiveness of herbal medicines for Kidney-yin-deficiency syndrome, bronchiectasis and gastric cancer. These studies suggest that the N-of-1 design is a study that encourages patient involvement, demonstrates the effectiveness of herbal medicines and helps reduce unnecessary medication. Conclusion: The N-of-1 clinical trial may be a rigorous methodology suitable for the clinical setting and may help the development of evidence-based Korean medicine. Attention is also needed in this research method in Korea.

This study was conducted to evaluate the clinical effectiveness of proton therapy as an advanced convergent cancer therapy. Clinical data of proton therapy were analyzed. As proton enters patient's body, it releases low dose of energy and shows an increasing energy deposition as it reaches certain point unlike x-ray. It may therefore reduce the radiation dose to the normal tissues in front and beyond the lesion and minimize the radiation damage. Proton therapy is expected to improve clinical outcomes and reduce treatment related toxicities. It is used in various cancers. Further studies are necessary.

Objective : Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluated the effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH). Methods : Between July 2008 and July 2013, 234 patients were included in this study. The LD group consisted of 126 patients, 108 patients in the non LD group. We investigated outcomes as follow : 1) clinical vasospasm, 2) angioplasty, 3) cerebral infarction, 4) Glasgow outcome scale (GOS) score at discharge, 5) GOS score at 6-month follow-up, and 6) mortality. Results : Clinical vasospasm occurred in 19% of the LD group and 42% of the non LD group (p<0.001). Angioplasty was performed in 17% of the LD group and 38% of the non LD group (p=0.001). Cerebral infarctions were detected in 29% and 54% of each group respectively (p<0.001). The proportion of GOS score 5 at 6 month follow-up in the LD group was 69%, and it was 58% in the non LD group (p=0.001). Mortality rate showed 5% and 10% in each group respectively. But, there was no difference in shunt between the two groups. Conclusion : LD after aneurysmal SAH shows marked reduction of clinical vasospasm and need for angioplasty. With this technique we have shown favorable GOS score at 6 month follow-up.

Clinical examination, photometric evaluation, & radiographic analysis have been used to evaluate the asymmetry of the face. Commonly used skull radiographs to assess skeletal asymmetry include poatero-anterior cephalometries, submentovertex view, & panoramic view. The purpose of this study is the comparison of the reliance of the postero-anterior cephalometric view, submentovertex view, & panoramic view in the asymmetry evaluation. All measurements were performed on the each radiographs of 31 control group & 30 asymmetric group. The measurements are MSL(midsagittal plane)-Co, MSL-Go, MSL-Me, MSL-Al, MSL-Bl, Mn. Ramus Height(Co-Go), Mn. Body Length(Go-Me), and Total Mn. Length(Co-Me). The results were as follows: 1. The lack of either a right-sided or left-sided asymmetric dominant was found. 2. The postero-anterior cephalometric view & submentovertex view relatively agreed with each other in the result. The postero-anterior cephalometric view & submentovertex view had the clinical reliability & effectiveness in the diagnosis of the skeletal asymmetry(p<0.05). 3. The panoramic view showed more magnification compared to the other radiographs. In the vertical measurements the panoramic view had clinical reliability relatively(p<0.05). But we cannot rely on the horizontal measurements in the panoramic view(p>0.05).

Objectives: Previous in vitro studies determined the whitening effects of bleaching products on stained resin composite surfaces. This in vitro study aimed to verify the effectiveness of a whitening system on composite resin previously subjected to pigmentation, specifically examining the depth of whitening effectiveness within the material structure. Materials and Methods: A commercially available nano-filled composite resin was used. Specimens were stained using a coffee-based solution and a 10% carbamide peroxide-based gel was employed as the whitening agent. The pigment's penetration and the effect of the bleaching gel were evaluated by measuring color (CieLab values) from the outer edge to the inner part of the specimens. Color measurements were taken at 14 points, starting from 0.1 mm from the external perimeter up to 3.0 mm. Results: Analysis of variance tests showed a statistically significant difference between the Control Group (CG), Pigmentation Group, and Whitening Group. The whitening agent was effective up to 1.5 mm in depth, with Whiteness index (W) values not statistically different from those of CG up to 0.5 mm in depth. Conclusions: Whitening agents on nano-filled resin composite previously pigmented appear effective in restoring the W to values similar to the original, particularly in the superficial layers of the sample.
