Objectives: The purpose of this study is to retrospectively evaluate the postoperative complication rates for absorbable type-I collagen sponge (Ateloplug; Bioland) use in third molar extraction. Materials and Methods: From January to August 2013, 2,697 total patients undergoing third molar extraction and type-I collagen sponge application in the Department of Oral and Maxillofacial Surgery at Yonsei University Dental Hospital (1,163 patients) and Dong-A University Hospital (1,534 patients) were evaluated in a retrospective study using their operation and medical records. Results: A total of 3,869 third molars in 2,697 patients were extracted and the extraction sockets packed with type-I collagen sponges to prevent postoperative complications. As a result, the overall complication rate was 4.52%, with 3.00% experiencing surgical site infection (SSI), 1.14% showing alveolar osteitis, and 0.39% experiencing hematoma. Of the total number of complications, SSI accounted for more than a half at 66.29%. Conclusion: Compared to previous studies, this study showed a relatively low incidence of complications. The use of type-I collagen sponges is recommended for the prevention of complications after third molar extraction.

The purpose of this study is to report the effect of combined acupuncture treatment on acute ankle sprain patients. The subjects included in this study were 15 acute ankle sprain patients who visited Jaseng Hospital of Korean Medicine from Oct. 15th, 2012 to Feb. 8th, 2013. We treated 15 patients with combined acupuncture treatment. The treatment con-sisted of Hwangrunhaedok-tang (Huanglianjiedutang) pharmacupuncture, electroacupunc-ture (applied to GB39, ST36 on the affected side), acupuncture (applied to TE17, SI6 on the unaffected side with Dong-Qi therapy). To assess the effect of treatment, the numeric rating scale (NRS) was applied before and after treatment. After first combined acupuncture treat-ment, the NRS scores significantly decreased from 8.33±0.94 to 2.26±0.44 (p<0.01). We suggested that Combined acupuncture treatment are effective and useful on acute an-kle sprain. And, further studies will be needed. (J Korean Med Rehab 2014;24(1):119-123)

The recognition of the esthetics as well as their function of the teeth in the dental field is growing. Evaluating the esthetics of a tooth concerns shape, texture, and color. And among these, color has been the most difficult element to make natural expression. Color is a very subjective element affected by many different factor like light source, object, observer. Numerous efforts to quantifying color has been made. Currently the use of colorimeter and spectrophotometercolor that the color measuring device has been suggested. In this study, the normal range of the tooth color in canines, lateral incisors and central incisors for Koreans was evaluated with a modified spectrophotometer for intraoral use. The color differences in terms of teeth positions, age and area within the tooth was evaluated and comparatively analyzed. Results were as follow ; 1. In all age groups, the central incisors are most bright and least yellowish opposit to the canines are most dark and yellowish. The central incisors and lateral incisors showed the similar color patterns. 2. In the comparison between gender, it showed that in the 10's group male have more yellowish, the 20's female have lighter and more redness, the 30's indicated more redness in female and in the 40's the lightness is more in female. 3. With aging, there was no significant change in L^* and a^* coordinates but a shift was in b^* to yellowish in the 30's and 40's in central incisors. Lateral incisors and canines showed a lighter and more yellowish tooth color with an irregular change of color coordinate in a^*. 4. In all teeth the middle and cervical portion showed close correlation with over 0.7(0.05>p) but color (a^*, b^*) showed higher correlation than lightness(L^*). 5. It has been shown that through the regression test the cervical color could be calculated by the middle color value.

생선회용 해산물에 오염되어, 생식한 경우 발생되는 패혈병의 원인균주인 Vibrio vulnificus의 생육 및 독성생성을 억제할 목적으로 천연 항균제인 Grapefruit종자추출물(GPSE)을 이용하여 그 항균효과를 검토하였다. In vitro 시험결과, Vibrio vulnificus에 대한 GFSE의 생육최소저해농도는 50~100 ppm 정도이었으며, Vibrio vulnificus 균체세포틀 100 ppm 농도의 GFSE 용액으로 처리하고 전자현미경 촬영시료로 조제하여 촬영한 후, 미생물형태을 무처리대조구와 비교, 검토한 결과, GFSE 처리로 세포막 기능이 파괴되어 세포내용물이 균체외부로 유출되어 균체의 생육이 억제되고 균체내부가 빈 ghost 형태의 균체수가 증대되어 GFSE의 항균효과를 확인할 수 있었다. 한편, 생선회용 해산물에 GFSE를 근육주사하고 Vibrio vulnificus를 접종한 수조내에서 사육하여 채취한 어육부를 마쇄하여 일정량씩을 표준사료에 첨가해서 통닭용 병아리를 실험동물로 하여 사양실험을 실시한 결과. 체중증가율, 단백질이용효율, 혈청내 효소활성, 혈청의 주요성분함량 등에 있어서, GFSE 처리수조내에서 사육한 해산물을 첨가한 시료시험구의 경우, 무첨가사료처리구와 비교할 때 뚜렷한 차이를 목격할 수 없었으며, GFSE 첨가에 따른 실험동물의 성장저해 또는 독성현상을 유발하지 않음을 알 수 있었다. 아울러, 각 처리구에서 사양한 해산물의 어육부에 오염된 Vibrio vulnificus의 균수를 측정한 결과, 250ppm 이상의 GFSE 처리구에서는 Vibrio vulnificus를 전혀 검출할 수 없었다. To prevent food-poisoning outbreaks by Vibrio vulnificus the antimicrobial efficacy of grapefruit seed extract (GFSE) was examined. Minimal inhibitory concentration (in vitro) for the microorganism was found to be 50~100 ppm. Transmission electron micrographs of Vibrio vulnificus showed the biocidal action of this natural antimicrobial agent would be related to specific respiratory effect coupled with the destruction of permeable function of microbial cell membrane. After Anguilla japonia GFSE-injected to the body was incubated in the seawater contaminated by Vibrio vulnficus the fish meats were taken up, mixed with control diet and used as a diet in the feeding experiment. In this experiment the effect of GFSE treated with fish muscle on body weight protein efficiency ratio, serum enzymes and serum blood component of broiler chicks was investigated. It is proved from this study that there is neither Vibriosis nor toxicity associated with GFSE itself and fish meats treated with it when it is injected to the fish body at a level of 250 ppm or less.

In this study, the characteristics of organics and nutrient removal from municipal wastewater with various operation conditions using modified intermittent aeration combined with HBR process was investigated. This system was operated with HRT of 10hr at COD/N 1.96, COD/P 75.3, sludge recycle of 50% to 100% and 18℃ to 25℃. It has been the best operating condition to control, Oxic/Anoxic time ratio setting rate has been set 40min/20min and 100% of sludge recycle, under the conditions such as 2hr HRT at the anoxic reactor, 6hr HRT at the aeration tank. In that conditions, the removal efficiency of BOD, COD, T-N and T-P were 97.5%, 91.7%, 75% and 76.2%, respectively. The SNR(Specific Nitrification Rate) was 3.213mgNH4-N/gMv/hr and the SDNR(Specific Dinitrification Rate) was 4.5mg NO3-N/gMv/hr. T-P removal efficiency is due to biological phosphorus removal and formation of chemical precipitates by pellet. The performance of wasted sludge dewatering in this process is better than wasted activated sludge.
