주관절 손산 중 상완골 내 상과 골절은 단독으로 혹은 주관절 탈구와 동반되어 발생하는 것이 일반적이다. 저자들은 15세 남자 환자의 좌측 요골 두 아탈구가 동반된 상완골 내 상과 골절을 경험하였다. 도수 정복을 시도하였으나 요골 두 아탈구의 정복을 얻을 수 없어 관혈적 정복술로 치료하엿다. 6개월추시 결과 후휴증이 없는 정상적인 관절 상태를 확인할 수 있었다. 연령, 원인 , 손상 기전으로 분석해 보면 이 동반 손상은 발생하기 매우 어렵고, 문헌 탐색 결과 현재까지 동일한 증례를 찾아볼 수 없었으므로 보고하는 바이다. It has been known that fracture of medial epicondylar apophysis of distal humerus may be isolated of associated with elbow deslocations. We have experienced a case which medial epicondylar fracture of the distal humerus was associated with subluxation of the radial head. Initially, we had tried reduction of subluxated radial head by closed method, but failed. Finally open reduction gad been performed. At 6 month after open reduction, clinical and radiological result were excellent. As it is difficult for those associated injuries to occur simultaneously and the similar cases never have been reported yet, we would like to present this case with a review of the literature.

목적: 골종양 환자나 외상, 골수염, 인공관절 치환술 등의 환자 등의 환자 치료에 많이 사용하는 장관골의 동종 이식에 대한 PRP (Platelet-Rich Plasma)의 효과를 토끼를 이용한 실험으로 알아보고자 하였다. 대상 및 방법: 20마리의 토끼를 대상으로 각각에 일련번호를 붙이고, 각 토끼의 양측 척골에 약 2㎝ 길이의 골편을 얻어 장관골 결손을 만들고 동시에 동종 장관골을 얻어, 홀수 토끼의 척골 골편을 짝수 토끼의 골결손 분위에 이식하고, 반대로 짝수 토끼의 척골 골편을 홀수 토끼의 골결손 분위에 이식하였다. 그 후 각 토끼의 좌측 척골 이식 부위에는 아무런 처치를 하지 않고 대조군으로 삼고, 우측 척골 이식부에는 PRP 0.7cc를 처치하여 실험군으로 삼았다. 술 후 0, 4, 8, 12주에 골이식부에 대한 방사선 촬영을 통하여 골유합 성적을 평가 비교하였다. 결과: 실험군의 척골 분절 결손부에서는 대조군에서보다 동종 분절골 이식부의 골유합이 방사선학적으로 향상된 것을 관찰 할 수 있었다. 결론: 동종 장관골 분절 이식시 PRP를 병용하여 사용할 경우 더욱 효과적인 신생조직 형성을 유도할 수 있으며, 임상에도 유용하게 적용할 수 있으리라 사료된다. Purpose: The purpose of this study was to evaluate the effect of Platelet-Rich Plasma(PRP) on the healing of the allograft for the treatment of the segmental bone defect of the ulna in Rabbits. Materials and Methods: About 2 ㎝-sized segmental bone defects were created on both ulna of twenty rabbits. The rabbits were divided into two groups, even and odd number groups after numbering them from 1 to 20. The segmental bone from the odd numbered animal was transplanted to the even numbered animal, and the even numbered to the odd numbered. The left side of the ulna was grafted with a segmental allograft only. The right side of the ulna was grafted with a segmental allograft and 0.7cc of PRP. Radiographs obtained at 0, 4, 8, and 12 weeks postoperatively were graded for radiologic union. Result: The use of the combination of PRP and segmental allograft demonstrated improved healing on radiographic study compared with that demonstrated after use of allograft alone. Conclusion: The results of the study suggests that the use of the combination of PRP and segmental allograft can be considered as an alternative method to manage the segmental defect of the long bone.

Mun, Jeong Ho,Chang, Yun Hee,Shin, Dong Ok,Yoon, Jong Moon,Choi, Dong Sung,Lee, Kyung-Min,Kim, Ju Young,Cha, Seung Keun,Lee, Jeong Yong,Jeong, Jong-Ryul,Kim, Yong-Hyun,Kim, Sang Ouk American Chemical Society 2013 Nano letters Vol.13 No.11

<P>Nanoscale alloys attract enormous research attentions in catalysis, magnetics, plasmonics and so on. Along with multicomponent synergy, quantum confinement and extreme large surface area of nanoalloys offer novel material properties, precisely and broadly tunable with chemical composition and nanoscale dimension. Despite substantial progress of nanoalloy synthesis, the randomized positional arrangement and dimensional/compositional inhomogeneity of nanoalloys remain significant technological challenges for advanced applications. Here we present a generalized route to synthesize single-crystalline intermetallic nanoalloy arrays with dimensional and compositional uniformity via self-assembly. Specific electrostatic association of multiple ionic metal complexes within self-assembled nanodomains of block copolymers generated patterned monodisperse bimetallic/trimetallic nanoalloy arrays consisting of various elements, including Au, Co, Fe, Pd, and Pt. The precise controllability of size, composition, and intermetallic crystalline structure of nanoalloys facilitated tailored synergistic properties, such as accelerated catalytic growth of vertical carbon nanotubes from Fe–Co nanoalloy arrays.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2013/nalefd.2013.13.issue-11/nl403542h/production/images/medium/nl-2013-03542h_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl403542h'>ACS Electronic Supporting Info</A></P>

하우스 베드재배 시 상토조성이 복령의 생육에 미치는 영향

Yong Mun Lee,Jeong Seop Mun,Song Hui An,Jong Yeop Kim,Hui Jun Kim 한국약용작물학회 2017 한국약용작물학술대회 발표집 Vol.2017 No.05

Background : The hyphal growth of Poria cocos are known to grow well under medium temperature(25 - 28 ℃) and acidic(pH 4.0 - 5.0) conditions. Also, it is known that a large difference in the yield of Poria cocos depending on the cultivation method and environment. Therefore, this research was carried out to secure stable yield of Poria cocos using plastic house and bed soil. Methods and Results : The inoculation time was in mid-April 2016 and the inoculation amount was 3/4 lb each in pine trees of 60 (L) × 10 (D) ㎝. The inoculated wood was buried directly in the bed by soil composition and growth characteristics investigated after cultivating in plastic house from April to September, 2016. The composition of the bed soil was 6 treatments using peatmoss, cocopeat and perlite. The combination ratio ranges of peatmoss, cocopeat and perlite were 0 to 80 %, 0 to 60 % and 20 to 60 %, respectively. We assumed that the combination ratio of peatmoss (organic material) 60 % : perlite(inorganic material) 40% is good for the growth of the Poria cocos. In this ratio, instead of peatmoss, the amount of cocopeat was replaced by 20, 40, and 60 %, respectively. The pH and EC range of bed soil was 4.8 - 5.6, 0.7 - 2.2 dS/m, respectively. pH and EC tended to be lower in treatments with only peat moss and perlite. On the other hand pH and EC tended to raise with increasing cocopeat content. Volumetric soil water content and soil temperature were in the range of 13 - 28 % and 20 - 29℃, respectively, during the period of July to September. Soil water content tended to be higher with increasing cocopeat and peatmoss content and soil temperature tended to be lower. The degree of initial hyphal development and sclerotia formation were good in all treatments compared to the control. However, the number of sclerotia was 6 times higher in the ② treatment than in the control. The size of sclerotia was also the best at 12 (L) × 8 (W) ㎝ in the ② treatment. Conclusion : As a result of cultivating Poria cocos in plastic house, growth characteristics were different according to composition of bed soil. The first reason for this result is that the difference of soil moisture content depending on organic matter content affected the soil temperature. Actually, the average soil water content and soil temperature of ① treatment (organic material 80% ) showed 24% and 22℃ respectively during July to September, and no sclerotia was formed. However, in the ② treatment(organic material 60%), the average soil moisture and soil temperature were 14% and 26℃ during July to September, respectively and sclerotia formation was good. Another reason is that the pH of the bed soil affects the formation of sclerotia. Overall, the degree of hyphal development was good in low pH treatments, but no significant difference was found between the pH and the formation of sclerotia.

Sacrococcygeal teratoma is the most common congenital tumor in neonates, and is reported in approximately 1/35,000 to 1/40,000 live births. Oligodendroglioma is a rare central nervous system tumor that is usually found in the cerebral hemisphere of young and middle aged adults. When associated with a teratoma, it is mainly identified in ovarian teratoma in adolescents and adults. We describe a rare case of a preterm infant with oligodendroglioma in a mature sacrococcygeal teratoma. The male neonate was born at a gestational age of 30 weeks with a protruding mass in the sacrococcygeal region. Pelvic magnetic resonance imaging showed a sacrococcygeal teratoma of approximately 11 cm comprising fat components and skeletal structure, that extended from the anterior part of the sacrum to the abdominal cavity. Radical resection was performed at 36 days of age. Macroscopically, the resected intra-abdominal mass had the characteristics of a cystic lesion, and the intrapelvic mass was a predominantly solid mixed cystic-solid lesion. Histologically, this solid lesion in the intrapelvic mass was composed of mature glial tissue, which comprised as a proliferation of monotonous cells with small and round nuclei, surrounded by a perinuclear halo (“fried egg” appearance). Additionally, these cells were immunohistochemically positive for glial fibrillary acidic protein. These findings confirmed the diagnosis of oligodendroglioma in sacrococcygeal mature teratoma. After the treatment, no recurrence was observed during the follow-up period, and no additional intervention was required. However, the patient is undergoing treatment for voiding dysfunction caused by a neurogenic bladder.
