  • Gastroesophageal reflux disease (GERD) is a disease that stomach contents continually refluxing, and is currently on the rise worldwide. The purpose of this study is to find natural materials that can reduce side effects and effectively treat chronic acid reflux esophagitis (CARE), one of GERD. First, the antioxidant activity was confirmed by varying the mixing ratio of Coptidis Rhizoma and Evodiae Fructus, which are effective against chronic reflux esophagitis. After, animal experiments were conducted using a 1:1 (CE) and 1:2 (CEE) combination ratio of Coptidis Rhizoma and Evodiae Fructus, which had the best antioxidant efficacy. Gross lesion of esophageal mucosa after CE or CEE treatment showed a superior enhancement compared with that of CARE control rats. Additionally, its inhibited MAPK phosphorylation and led NF-κB inactivation through the suppression of IκBα phosporylation by regulating Nrf2/Keap-1, and NF-κB inactivation induced reduced protein expressions including inflammatory mediators and cytokines. Moreover, its improved esophageal barrier function through upregulating protein expressions of tight junction protein, whereas downregulating protein expressions of MMPs. Taken together, a mixture of Coptidis Rhizoma and Evodiae Fructus can attenuate the esophageal mucosal ulcer by inhibiting MAPK and NF-κB pathway, and upregulating proteins associated with tight junction.

  • Objective : This study was designed to investigate anti-oxidative, anti-aging and anti-inflammatory activities of Zingiber officinale Roscoe water (ZD) and 50% ethanol extracts (ZE). Method : The antioxidant capacity of ZD or ZE was analyzed by DPPH, ABTS scavenging activities and reducing power, respectively. The anti-aging efficacy was performed with tyrosinase and collagenase inhibition activities. The anti-inflammatory activities were confirmed through inhibition of nitric oxide production and TNF-�� expression in LPS-treated Raw 264.7 cells. Result : As a result of measuring DPPH and ABTS radical scavenging activities, both ZD and ZE extracts increased in concentration-dependent manners. The ABTS radical scavenging activities of water and 50% ethanol extract were similar to that of positive control at high concentration. On reducing power, both ZD and ZE showed higher activities than the positive control at high concentration. On inhibition activities of tyrosinase and collagenase both ZD and ZE showed the large inhibition rates at low concentration. Also, the inhibitory efficacy of ZD on NO and TNF-�� production was better than ZE in RAW 264.7 cells. Conclusion : These results suggest that ZD and ZE have anti-oxidative, anti-aging and anti-inflammatory effects in vitro. Especially, ZD was more effective than ZE. Thus, Ginger extract is considered to be highly useful as a cosmetic or food material with anti-oxidative, anti-aging (prevention of whitening and wrinkle) and anti-inflammatory effects. Also these effects may vary depending on the extraction solvent.

  • Objectives: To compare bone proportional cun and finger-breadth cun in the head area to clearly distinguish the anterior hairline. Methods: In this study, the head area was measured for 50 adult males and females in their 20s with normal hair condition. We compared bone proportional cun and finger-breadth cun in the head area and calculated the error by analyzing the difference between the actual location of the anterior hairline and the location measured with the two methods. Results: There was a significant difference between bone proportional cun and finger-breadth cun in the head area. The two methods showed significant difference from the actual location of the anterior hairline. In addition, as a result of calculating the error between the actual location of the anterior hairline and the location measured by the two methods, the finger-breadth cun had fewer errors than the bone proportional cun. Conclusions: The finger-breadth cun is better than the bone proportional cun as an alternative when it is difficult to find the anterior hairline.

  • Implant-assisted removable partial denture (IAPRD) can be considered as a simple and cost-effective treatment approach for an edentulous patient with anatomical or financial limitations. Recently, it was reported that the application of IARPD with implant supported fixed prostheses covered by the National Health Insurance Service (NHIS) were increasing. This case report describes the treatment of maxillary fully edentulous patient with anterior four-implant-supported fixed prosthesis and distal extension IARPD. This treatment approach may be advantageous over maxillary implant overdentures in some circumstances. The patient was satisfied with improved function and esthetics in the anterior area and financial benefit from the NHIS. Further long-term clinical studies are needed to establish clinical validity of the treatment approach described in this case report.
