Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Codonopsis lanceolata. Three tetraploid plants of C. lanceolata were produced from seeds which absorbed 0.1 % colchicine solution for 12 hours, and 0.5% colchicine solution for 1 and 6 hours from seedlings, respectively. But tetraploid was not produced from shoot tips treated by colchicine solution. Compared to diploid, tetraploid plants had larger stomata, but less number of stomata. Fresh weight of tetraploid plants was 1.4∼3.6 times heavier than diploid plants.

Kim,Ik-Hwan,Kim,Hag-Hyun,Hong,Eui-Yon,Yun,Jong-Sun,Yun,Tae,Hwang,Ju-Kwang,Lee,Cheol-Hee 한국자원식물학회 2003 Plant Resources Vol.6 No.3

Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Platycodon grandiflorum in Campanulaceae. The most successful colchicine treatment for tetraploid production in P. grandiflorum was soaking treatment using 0.01 and 0.5% colchicine solution for 1 hour and 12 hours, respectively. Morphological characteristics of both diploid and tetraploid were similar, but tetraploid plants had more leaves. Compared to diploid, tetraploid had the larger stomata, but less number of stomata. Fresh weight of tetraploids was 20∼40% heavier than that of diploid.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Days to flowering and maturity had a get tendency to be short according as delaying the seeding, the number of pods and 100 seed weight had a tendency to increase by the early seeding, although there were no significant differences of seeding time on the stem length, number of branches, and number of main stem nodes, respectively. Yield of each soybean variety showed the highest value at the plot seeded on 20th June, and the corresponding value was low at the plot seeded on 5th June. Oil contents in both tested soybeans had a tendency to increase according as delaying the seeding, however, proteins showed an increasing tendency according as the earlier seeding date. The contents of histidine, valine, tryptophan, and alanine had also a tendency to increase according as the earlier seeding date. On the contrary, the contents of theronine, methionine, lysine, serine, and proline were respectively increased according as delaying the seeding. The contents of glycine and threonine showed the highest level at the plot seeded on 20the June. Among the contents of minerals in each tested soybean, potassium content was low at the plot seeded on 20th June, although there were no regular tendency of the treatments.

金護哲,朴珠瑛,安德均 대한본초학회 1999 大韓本草學會誌 Vol.14 No.1

Balsanpungyeolyak, Expelling Pathogenic Wind-Heat Drug, have been used to treat the symptoms such as fever, headache, neck stiffness and skin disturbance which are commonly shown in systemic fever disease like influenza. We thought that the symptoms from the actions of wind and heat in Traditional Korean Medicine are similar to the ones of hypertensive patients in clinic. We chose five drugs among expelling pathogenic wind-heat drugs, Puerariae Radix, Chrysanthemi Flos, Menthae Herba, Mori Folium, and Arctii Fructus, to investigate their antihypertensive effects on S.H.R. and normotensive S.D rats, direct relaxant activity on isolated rabbit aorta, and ACE inhibitory activity. Menthae Herba and Arctii Fructus decreased blood pressure significantly in SHR, but not in normotensive rats, Direct vasodilatative effects on isolated rabbit aorta was not observed in any group. Chrysanthemi Flos, Menthae Herba, Mori Folium, and Arctii Fructus inhibited the actions of ACE dose-dependently. Therefore it is concluded that expelling pathogenic wind-heat drugs has not direct correlation with antihypertensive activity. However, it can be suspected that some drugs for dispersing the actions of wind and heat may regulate blood pressure through ACE inhibition and further study will be helpful to understand the mechanism.

구치부 복합레진의 인장강도에 관한 실험적 연구

김재곤,이용희,양철희,백병주 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.3

1960년대 수복재로서 복합레진이 소개된 이래, 심미성이 우수하고 치질에 대한 접착성이 있는 복합레진이 전치부 수복용 재료로서 널리 사용되어 왔으며, 최근 레진과 필러의 개선에 의해 기계적 성질 내마모성 등의 물리적 성질이 크게 증가하면서 구치부 수복용 재료로서도 점차 그의 응용이 확대되고 있지만. 높은 음력이 작용하는 구치부의 경우 그 사용이 제한적이고 임상적인 예후가 불확실하다는 단점이 있어왔다. 초기의 구치용 복합레진의 예후의 보고에 의하면 비교적 초기에 변연파절이 발현하고 있는 듯하다. 이런 원인으로써는 재료 자신의 강도 접착기법,환경요인등 여러 가지 물성이 복잡하게 영향하고 있다고 생각되어지기 때문에 간단히는 설명할 수 없지만, 일반적으로 취성재료가 인장응력으로 파단하는 것을 생각하면 구치용 복합레진의 인장강도에 대해서 상세히 검사할 필요가 있다고 생각한다. 본 연구에서는 구치부 수복용 복합레진의 인장강도를 평가하기 위해. 5종의 광중합 복합레진(Denfil(Vericom, Korea), P6O(3M,U.S.A.), Unifil S(GC, Japan), ZIOO(3M, U.S.A.), Z250(3M, U.S.A.))을 시험재료로 선택하여 소형인장시험편을 제작한 다음 thermal cycyling과 시효처리를 시행한 후 직접 인장시험법에 의해 인장강도를 측정하고 다음과 같은 결론을 얻었다 1.P6O의 인장강도는 타 실험군인 Denfil, Unifil S, Z1OO에 비해 유의성 있게 높은 수치를 보였다(p<0.05). 그러나 Z25O과는 유의한 차이를 보이지 않았다(p>0.05). 2.Denfil은 타 실험군인 P6O, Unial S, ZIOO. Z25O 모두에 비해 유의성 있게 낮은 수치를 보였다(p<0.05) 3.Unifil S와 Z100은 P6O과 Z250보다 낮은 수치를 나타냈으나(p<0.05). Denfil보다는 증가된 수치를 나타냈다. (p<0.05): Unifil S와 Z100간의 유의한 차이는 없었다(p<0.05). The purpose of this study was to evaluate the tensile strength of light-cured restorative posterior resin-based composites. Five commercially available light-cured composites(Denfil : DF, P6O : PS, Unifil S : US, Z100 : ZH, Z250 : ZT) were used. Rectangular tension test specimens were fabricated in a teflon mold giving 5mm in gauge length and 2mm in thickness. Specimens were subjected to the 5,000 thermal cycles between 5℃ and 55℃ and the immersion time in each bath was 15 second per cycle. Tensile testing was carried out with Instron at a crosshead speed of 0.5mn/min and fractured surface were observed with scanning electron microscope. The obtained results were summarized as follows ; 1. The tensile strength of PS was highest. PS was significantly higher than DF, US and ZH(p<0.05). but in the case of ZT was similar to PS(p>0.05) . 2. The tensile strength of DF was lowest. DF was signigicantly lower· than PS, US, ZH and ZT(p<0.05) . 3. The tensile strength of US and ZH were significantly lower than PS and ZT(p<0.05) but were significantly. higher than DF(p<0.05) . The tensile strength of US and ZH were similar(p>0.05).
