Agrobacterium rhizogenes 에 의하여 유도된 도라지 ( Platycodon grandiflorum DC. ) Hairy Root 의 배양
김병로(Byung Ro Kim),이재혁(Jae Hyuk Lee),황백(Baik Hwnag) 한국식물학회 1990 Journal of Plant Biology Vol.33 No.3
Induction and culture of hairy roots by Agrobacterium rhizoenes A_4 were carried out in Platycodon grandiflorum DC. After 2-4 weeks of inoculation with Agrobacterium rhizogenes hairy roots were formed at root segments in the balloon flower. Optimized growth of hairy roots was obtained in hormone-free MS medium, 6% sucrose and pH 5.8. The pattern of ginsenoside in the transformed roots was not different with that in the ordinary roots.

Understanding of the properties of woods is important in wood utilization. Until now, traditional wooden houses(korean-style house, Buddhist temple, royal palaces) and furniture have been made of domestic woods with the experience of a craftsman rather than the scientific knowledge on woods. Because of concrete-based houses and imported wood products and furniture, even wood craftsmen decrease in number, too. This study was carried out to collect wood samples growing in Korea and to measure wood characteristics. Anatomical, physical and mechanical properties of 37 wood species were investigated.

본 연구는 우리나라에서 주요 용재로 사용되고 있는 소나무의 생장지역에 따른 해부학적 특성을 조사하기 위하여 실시하였다. 지역 간 비교를 위해 태백산맥을 기준으로 영동(고성), 영서(홍천), 영남(봉화) 세 지역을 선정하였다. 같은 연도에 형성된 연륜을 사용하기 위해 연륜연대학의 크로스데이팅법으로 벌채연도를 분석한 결과, 고성, 홍천 및 봉화 산 목재의 벌채연도가 각각 2014, 2012, 2014년으로 나타났다. 분석된 벌채연도를 토대로 각 지역에서 채취된 소나무의 미성숙재(수부터 20번째 연륜까지), 심재(연륜 생성연도: 1955∼1964y), 변재(연륜 생성연도: 2002∼2011y)를 대상으로 가도관 길이와 직경을 측정하였다. 산지 간 가도관 길이는 미성숙재에서는 차이를 보이지 않았으나 심재와 변재부에서는 봉화, 홍천 고성 산 순으로 나타났다. 가도관 직경의 경우도 봉화 산이 높게 나타났다. 가도관 길이의 방사방향변이는 약 20년 전후에 증가하다가 안정되는 경향을 보였다. 현미경을 이용한 목재해부학적 관찰에 따르면 세 지역 모두 전형적인 소나무의 특성을 보였다. This study was fulfilled to investigate the anatomical characteristics according to provinces. In order to compare anatomical characteristics between provinces we selected Goseong, Hongcheon, and Bonghwa as experimental sites. To use the tree rings formed at the same years we dated all tree rings by cross-dating method used in dendrochronology and the cutting years were successfully dated in 2014, 2012, and 2014 for woods from Goseong, Hongchen, and Bonghwa, respectively. Based on the cutting years tracheid lengths and widths were measured considering juvenile wood (tree rings between the pith and first 10 years), heartwood (tree rings formed between 1955 and 1964), and sapwood (tree rings formed between 2002 and 2011). According to the results about differences between tracheid lengths from three provinces, juvenile wood did not show a difference, statistically, but heartwood and sapwood showed differences as the tracheid lengths following Bonghwa, Hongcheon, and Goseong. Bongwha also showed the largest value in the trachied width among three provinces. The tracheid lengths in the radial direction increased up to around the first 20 years, and then they showed stabilized. All wood samples showed typical Korean red pine’s characteristics in anatomical observation under a light microscope.

목탄을 이용한 미네랄수의 제조가능성을 알아보기 위해, 목탄의 무기성분 용출 및 수소이온농도 및 잔류염소흡착 성능을 조사하였다. 무기성분 용출은 탄화온도가 높아짐에 따라 칼륨의 경우 용출량이 높아지나, 나머지 무기성분들의경우 차이가 적었다. 무기성분 용출량은 각 수종에서 칼륨이 가장 높은 값을 나타냈고 다음으로는 나트륨, 칼슘 순으로 나타났고, 수종 간에는 칼륨의 경우 활엽수인 굴참남무와 버즘나무가 침엽수인 소나무, 낙엽송 및 잣나무에 비하여현저히 높게 나타났고, 나머지 무기성분은 수종간 칼륨만큼 큰 차이는 없었으나 칼륨과 같은 경향을 나타냈다. 수소이온농도는 활엽수인 버즘나무(600℃의 경우 pH 8.5)와 굴참남무(pH 8.4)가 높게 나타났고, 낙엽송(pH 7.8), 소나무(pH 7.2), 잣나무(pH 7.0)가 앞의 두 수종보다 낮은 값을 나타냈다. 염소제거량은 모든 수종에서 대조구보다 높은 제거량을 나타냈고, 침엽수인 잣나무와 소나무가 활엽수인 낙엽송, 버즘나무, 굴참나무보다 높은 제거율을 나타냈다. 분말목탄과 각형목탄 간 무기성분 용출량 및 수소이온농도에서 차이가 없으므로, 목탄을 이용한 미네랄수 제조에는 분말목탄보다 제조도 용이하고, 용출 후 처리도 용이한 각형목탄이 좋을 것으로 생각된다. To evaluate wood charcoal as raw material for mineral water production, dissolution of inorganic ions from charcoal to water, pH and adsorption ability of chlorine in water were investigated as main variables. More potassium ion was dissolved in water as higher temperature manufactured charcoal but other ions showed no difference with different charcoal making temperatures. Highest dissolved cation was potassium followed by calcium and sodium. Among wood species, charcoal from Quercus variabilis and Platanus occidentalis showed significantly higher potassium content in water than that of larch, red pine and white pine. Other cations had similar pattern to the potassium but their difference was not apparent as much as potassium. pH value of water treated with charcoal was higher for wood charcoals from Platanus occidentalis (pH 8.5) and Quercus variabilis (pH 8.4) which contained higher inorganic cations. In chlorine removal in water by charcoal, all wood charcoals showed greater chlorine removal than that of the control, but softwood charcoals resulted in higher removal than those of hardwoods. There was no significant difference in the dissolution of cations and pHs between particle charcoal and whole charcoal. With easy of control, whole charcoal is better for mineral water making raw material than particle charcoal does.

N/A Ulcerative colitis is a diffuse inflammatory disease of the mucosal lining of the colon and rectum without apparent cause. Ulcerative colitis is relatively frequent in the western countries but is extremely rare in Korea. This report is an analysis of 26 cases of ulcerative colitis which treated in the Yonsei Medical Center from Jan. 1970 to Aug. 1983. The results were as following: 1) The most prevalent age group was 5th decade and male to female ratio was 1.36:1%. 2) The most common clinical manifestation was bloody diarrhea. 3) According to the ariatomical site of the lesion, pancolitis was most common but proctitis was relatively rare than other reports. 4) By medical treatment, improvement was noted in 68.2%. 5) Operations were performed in 8 cases, and its indications were intractability 1 case, massive bleeding 1 case, suspected carcinoma 2 cases, toxic megacolon 2 cases and perforation 2 cases. 6) Postoperative mortality was 62.5% but all of the 5 cases, treated by emergency, were died and all of the 3 cases, treated by elective operation, were survied. 7) Cause of death was sepsis in all.
