This study was conducted to induce somatic embryogenic callus (SEC) derived from petals in rose. The petal explants of 3 cultivars ('Ice Wing', 'Orange Eye' and 'Pink Beauty') with different flower colors were placed on three types media (MS, SH and WPM) supplemented with 11 mg/L 2,4-D, respectively, and then cultured in the dark for 47 days. Calluses were formed at explants of all three cultivars. Also, 'Ice Wing', which were cultured in the SH as the basal medium, showed the highest callus formation rate. However, somatic embryos were generated from only petal-derived callus of 'Ice Wing', which were induced on the WPM as the basal medium, transferred it to SH basal medium supplemented with 3 mg/L 2,4-D, and 300 mg/L L-proline, and cultured for 5 weeks. The SEC has been proliferated every four weeks at the subculture interval. In addition, as a results of making a comparison of expression of RhSERK3 and RhSERK4, which is used as signal for generation of somatic embryo from callus in rose, between the SEC and petal-derived callus from 'Ice Wing' by RT-qPCR, the former showed 10 times higher RhSERK3 expression and 700 times higher RhSERK4 expression than the latter.

혈장 혈액응고인자 XIII(프로트란스글루타미나제)의 비촉매 사슬의 반감기

이수영,박란숙,Lee, Soo-Young,Park, Lan-Sook 생화학분자생물학회 1982 한국생화학회지 Vol.15 No.4

혈장혈액응고인자 XIII은 $a_{-2}b_{-2}$형의 효소원으로서, 트롬빈에 의해 활성화되어 효소형인 transglutaminase가 된다. transglutaminase는 ${\epsilon}-({\gamma}$-glutamyl) lysine cross-link를 통한 피브린의 cross-link반응을 촉매한다. $a_{-2}b_{-2}+b_{-2}*{\rightleftharpoons}a_{-2}b_{-2}*+b_{-2}$반응이 일어남을 in vivo 및 in vitro에서 확인하였고, $a_{-2}$ 결핍토끼에서의 $b_{-2}$의 반감기는 4.5시간이었다. 이 사실은 순환혈액속에서 $a_{-2}b_{-2}$형만이 오래 머무를 수 있음을 보여주었다. Rabbit plasma blood coagulation factor XIII(protransglutaminase), like the human zymogen, is a tetramer $(a_{-2}b_{-2})$ as is the enzyme$(a_{-2}b_{-2})$(transglutaminase, E.C. 2.32 13) formed by thrombin activation in the absence of $Ca^{2+}$. Transglutaminase from its zymogen, blood coagulation factor XIII, catalyzes the covalent intermolecular polymerization of fibrin through formation of ${\epsilon}-({\gamma}$-glutamyl) lysine crosslink. Since $a_{-2}b_{-2}+b_{-2}*{\rightleftharpoons}a_{-2}b_{-2}*+b_{-2}$ occurs both in vitro and in vivo, the half-life of $b_2$ in $a_2$-deficient rabbit is 4.5 hours. These results suggest that only tetramer form$(a_{-2}b_{-2})$ of a plasma coagulation factor XIII could sustain longer in blood plasma.

Due to the irregularity of walking ground and the inaccuracy in trajectory control of a leg, the mechanical shock and slip on the ground can be caused in the landing and supporting legs of a walkin g robot, and the robot may lose walking stability. Especially in a jointed-leg type walking robot, those problems are much more severe than in the pantograph type since the leg-weight of the jointed-leg type walking robot is relatively heavier than that of the pantograph type in general. In order to secure the walking stability for the jointed-leg type quadrupedal robot under development in KIST(Korea Institute of Science and Technology), a balancing algorithm consisting of the leg compliance control and the body posture control is implemented in this paper, and the effectiveness of the algorithm is verified through experiments.

Kelpak^® 침지 처리에 의한 형질전환 장미 기내 식물체 발근 촉진

이수영,권오현,이혜진,김원희,Lee, Su Young,Kwon, O Hyeon,Lee, Hye Jin,Kim, Won Hee 한국식물생명공학회 2014 식물생명공학회지 Vol.41 No.4

도입 유전자의 영향으로 발근유도배지(NAA $0.03mg{\cdot}L^{-1}$ 첨가 MS배지)에서도 발근이 잘 되지 않는 SOD2유전자 도입 장미 형질전환체의 $Kelpak^{(R)}$ 침지에 의한 발근 촉진가능성을 조사하였다. $Kelpak^{(R)}$ 액에 침지 후 발근유도배지에 배양 4주 후 장미 SOD2형질전환체의 기내뿌리 유도 및 뿌리생장이 촉진되었다. 또한 대조식물체인 비형질전환식물체도 $Kelpak^{(R)}$ 침지 처리후 발근유도배지에 배양하는 것이 $Kelpak^{(R)}$ 처리 없이 발근유도배지에 배양하는 것보다 뿌리수도 증가했을 뿐 아니라 뿌리길이 생장도 증진된 것으로 볼 때 $Kelpak^{(R)}$이 장미 기내식물체의 발근 촉진에 효과적인 것은 분명하다. In order to promote in vitro rooting in SOD2-transgenic rose plantlets, which were not well rooted in a rooting medium (MS medium with NAA $0.03mg{\cdot}L^{-1}$), we dipped the plantlets into liquid $Kelpak^{(R)}$ before placing them in the rooting medium. After 4 weeks, $Kelpak^{(R)}$ significantly promoted in vitro rooting in the plantlets. Therefore, $Kelpak^{(R)}$ can be used successfully to aid in the in vitro rooting of rose plantlets with roots that are not well-generated.

Purpose: To compare the efficacy of intravitreal gatifloxacin with intravitreal vancomycin in the treatment of Staphylococcus epidermidis endophthalmitis in a rabbit model. Methods: Albino rabbits (n=30), infected with an intravitreal inoculum of S. epidermidis (105 colony forming unit/0.1 mL), were divided into 6 groups (n=5). Groups I and IV received 200 μg/0.1 mL of intravitreal gatifloxacin, and groups II and V were injected 1000 μg/0.1 mL of vancomycin intravitreally. Intravitreal balanced salt solutions (untreated control) were given to Groups III and VI. Intravitreal antibiotic therapy commenced 24 hours after bacterial inoculation. The bactericidal efficacy was determined by electroretinography (ERG), clinical grading, bacterial culture of vitreous aspirates and histopathologic grading. ERGs and clinical gradings were performed only for groups I, II, and III and bacterial cultures were done only for groups IV, V, and VI. Results: Eyes in the gatifloxacin groups showed similar appearance to those in the vancomycin treated groups clinically, histologically, and functionally as proved with ERG. All aspirates from the gatifloxacin and vancomycin groups were culture‐negative at 5 days after bacterial inoculation, whereas all eyes in the untreated control group were culture‐positive. Conclusions: This study demonstrated that intravitreal injection of 200 μg /0.1mL gatifloxacin appeared to be equally effective compared to intravitreal 1000 μg /0.1 mL vancomycin in the treatment of S. epidermidis endophthalmitis. If proven safe and efficacious after further study in humans, intravitreal injection of gatifloxacin could be considered an effective alternative to vancomycin for the treatment of S. epidermidis endophthalmitis.

가상 환자 데이터 세트는 단일 환자로부터 획득한 구강스캔 안면스캔 전신스캔 하악운동경로데이터 등 다양한 소스의 진단 데이터를 하나의 3차원 좌표계로 정렬한 데이터의 집합이다. 치과의사는 가상 환자 데이터 세트를 사용하여 효과적으로 치료 계획을 수립하고 다양한 치료 계획을 가상공간상에서 시뮬레이션 할 수 있으며, 가상 환자 데이터 세트에서 환자의 미소를 디자인 후 그 결과를 시뮬레이션하고 최적의 치료결과를 선택할 수 있다. 가상공간에서 선택된 치료 계획은 3D 프린팅, 밀링, 사출 성형과 같은 제조 기술을 사용하여 환자에게 동일하게 전달될 수 있다. 이러 치료 계획의 전달은 임시 수복물 제작 및 환자의 구강 내에서 목업 확인을 통해 최종 보철물 제작으로 연결할 수 있다. 이와 같이 진단 데이터, 중첩 및 가공의 정확도가 보장된다면 3차원 가상공간 상에서 시뮬레이션된 3D 디지털 스마일 디자인을 실제 환자에게 정확하게 전달할 수 있다. 가상환자데이터세트의 임상적용방법으로 동기능적교합측정 검사를 통해 교합조정치료를 치료계획에서 배제할수 있는 의사결정방법과, 턱관절질환을 가지고 있는 청소년기 특발성 척추측만증 환자의 턱관절 치료전후 전신스캔 비교분석방법, 그리고 전악수복증례인 상하악 총의치환자 진료시 가상환자데이터세트에 기반한 교합평면분석 및 디지털심미분석방법을 제시하였다. The virtual patient dataset is a collection of diagnostic data from various sources acquired from a single patient into a coordinate system of three-dimensional visualization. Virtual patient dataset makes it possible to establish a treatment plan, simulate various treatment procedures, and create a treatment planning delivery device. Clinicians can design and simulate a patient's smile on the virtual patient dataset and select the optimal result from the diagnostic process. The selected treatment plan can be delivered identically to the patient using manufacturing techniques such as 3D printing, milling, and injection molding. The delivery of this treatment plan can be linked to the final prosthesis through mockup confirmation through provisional restoration fabrication and delivery in the patient's mouth. In this way, if the diagnostic data superimposition and processing accuracy during the manufacturing process are guaranteed, 3D digital smile design simulated in 3D visualization can be accurately delivered to the real patient. As a clinical application method of the virtual patient dataset, we suggest a decision-making method that can exclude occlusal adjustment treatment from the treatment plan through the digital occlusal pressure analysis. A comparative analysis of whole-body scans before and after temporomandibular joint treatment was suggested for adolescent idiopathic scoliosis patients with temporomandibular joint disease. Occlusal plane and smile aesthetic analysis based on the virtual patient dataset was presented when treating patients with complete dentures.

This case report describes a patient with olivopontocerebellar atrophy accompanied by sleep disorder and gait disturbance whose condition was improved by treatment with Korean medicine. The 61-year-old woman, who was diagnosed with olivopontocerebellar atrophy (Multiple Systemic Atrophy-Cerebellum), was admitted to hospital twice and treated with Korean medicine (acupuncture and herbal medicine) and rehabilitation. The Korean medicine was Gwibiondam-tang-gami and Jaeumgeonbi-tang-gami. Clinical symptoms were assessed by the Modified Bathel index, functional independent measurement, Berg balance scale, and Unified Multiple System Atrophy rating scale. A brain MRI at the one-year follow up after onset showed similar progress but clinical symptoms were improved after treatment, and the evaluation index score increased. Multiple system atrophy, a type of degenerative neurological disease, has no targeted treatment. In this situation, although this report describes a single case, Korean medicine treatment could provide a meaningful improvement in the sleep disturbance and gait disorder symptoms of patients with olivopontocerebellar atrophy.

The purpose of this study was to evaluate the reproducing accuracy of stone casts made from complete arch impressions using different impression materials. The impression materials studied were 1) polyether, 2) polysulfide, 3) polyvinyl siloxane, and 4) irreversible hydrocolloid. Impressions were made from a partially edentulous acrylic resin model with metal inserts in canine, first molar region bilaterally and mid palatal vault region. Each distance between 2 out of 5 meauring points was measured by using 3dimensional measuring machine. Impressions were poured at once with a type IV dental stone. Data were analyzed using t-test with a sample size of six. The results were as follow : 1. Polysulfide and polyether were significantly superior to polyvinyl siloxane and irreversible hydrocolloid in reproducing full arch model(p<0.05), but there were no statistical differences in amount of dimensional reproducing accuracy for full arch impression between polysulfide and polyether(p>0.05). 2. There were statistical differences in amount of dimensional reproducing accuracy between edentulous area and tooth bound area for polysulfide and polyether(p<0.05). but no statistical differences were observed for polyvinyl siloxane and irreversible hydrocolloid(p>0.05).

Purpose : This study was undertaken to evaluate the immunogenicity and reactogenicity of Td booster immunization in early preadolescents of Korea. Methods : Healthy preadolescents, who had been vaccinated with 4 or 5 doses of DTaP vaccines until 6 years old age, were enrolled in this study from August 2006 to April 2007. Diphtheria and tetanus anti-toxoid antibodies in sera were measured by ELISA just before vaccination and 4 weeks after vaccination to evaluate immunogenicity. Local and systemic adverse reactions observed for 4 weeks after vaccination to access reactogenicity. Results : 183 preadolescents were enrolled and mean age was $11.40{\pm}0.51$ years old. All subjects achieved seroprotective diphtheria and tetanus anti-toxoid antibodies (titers ${\geq}0.1IU/mL$) after Td booster vaccination. Among 183 vaccinees, 73.8% showed local adverse reactions and 37.2% systemic adverse reactions. Pain at injection site (66.1%) was the most common local reaction, and the most commonly shown systemic reaction was myalgia (17.5%). The adverse reactions were spontaneously relieved within three days after vaccination. Conclusion : Td vaccine in this study was high immunogenic and showed an acceptable tolerance in Korean preadolescents. Td booster vaccination at 11-12 years old is the most effective method to increase compliance of the vaccination and to decrease the incidence of diphtheria and tetanus. 목 적: 11-12세 연령에 Td 백신 1차 추가접종을 하는 방법에 대한 면역원성과 안전성을 평가하기 위해 연구를 계획하였다. 방 법: 2006년 8월부터 2007년 4월까지 연구병원 소아청소년과 외래에 Td 백신 접종을 받기 위해 내원한 11-12세의 소아를 대상으로 하였다. 면역원성을 평가하기 위하여 접종 전 및 접종 4주 후에 혈액을 채취하여 디프테리아 및 파상풍에 대한 항독소 항체가를 측정하였고 이상반응을 평가하기 위해 관찰 일지에 국소 및 전신 이상반응을 기록하였다. 결 과: 총 183명이 연구에 참여하였고 이들의 평균 연령은 $11.40{\pm}0.51$세이었다. Td 백신 접종 전후의 GMC는 디프테리아에 대해서는 10배, 파상풍에 대해서는 26배 이상 증가하였고, 접종 후 디프테리아와 파상풍에 대한 항체 양전율(항체가 ${\geq}0.1IU/mL$ 기준)은 100%이었다. 디프테리아의 접종 전 항체가가 0.1 IU/mL 이상인 피험자는 142명(77.6%)이었고 접종 후 항체가가 1.0 IU/mL 이상인 피험자는 174명(95.1%)이었다. 파상풍의 접종 전 항체가가 0.1 IU/mL 이상인 피험자는 146명(79.8%)이었고 접종 후 항체가가 1.0 IU/mL 이상인 피험자는 181명(98.9%)이었다. 접종 후 국소 이상반응이 73.8%, 전신 이상반응은 37.2%에서 발생하였으나 대부분 3일 이내 소실되었다. 결 론: 매우 높은 면역원성과 심하지 않은 이상반응을 고려할 때, Td 백신의 접종을 11-12세 시행하는 것은 디프테리아와 파상풍에 대한 가장 경제적인 방어 수단이며, 접종 순응도를 효율적으로 높일 수 있는 방법이다.
