고석찬,허인옥,고정군 제주대학교 1993 논문집 Vol.37 No.-

. The properties of concanavalin A(Con A) was investigated in the mature seeds and the quantitative changes of Con A was studied in the cotyledons during germination and growth of Canavalia lineata. Con A was isolated from the crude extract by Sephadex G-50 in mature seeds and the isolated Con A was separated as four subunits with molecular weights of 30 kD, 21 kD, 17 kD and 11 kD by SDS-PAGE, but Con A subunits with 21 kD, 17k/d and 11kF did not have immunoaffinity for 30kD subunit. About 75㎍ of Con A agglutinated 50μ1 of 1% human erythrocytes and Con A was bound to horseradish peroxidase. Con A subunit with 30kD decreased rapidly 8 days after sowing and the subunits with 17 kD and 11kD decreased remarkably 12 days after sowing, indicating that Con A is hydrolyzed by proteases at late stage of germination.

The characteristics of chlorophyll fluorescence were studied in the leaves of Sargent juniper (Juniperus chinensis var. sargentii) and crowberry (Empetrum nigrum var. japonicum) under natural field conditions. The photochemical efficiency of photosystemⅡ(PSⅡ), Fv/Fm, was slightly lower in the leaves of Sargent juniper than in those of crowberry, and the non-photochemical fluorescence quenching (NPQ) was higher in the leaves of Sargent juniper. In both species, the Fv/Fm values decreased temporarily at midday. This midday photoinhibition was more severe in Sargent juniper than in crowberry. Between Fv/Fm and environmental factors, there was no significant relationship with any factor in Sargent juniper leaves, while there were significant relationships with all factors in crowberry leaves. These results suggest that Sargent juniper has the mechanism for protecting or avoiding the photodamage although it is more sensitive to environmental changes than crowberry.

부종휴의 제주도 자생식물 종 발표에 대한 해석과 의의

부종휴에 의해 1964년에 제주도 자생식물로 발표된 333종의 학명을 중심으로 분석한 결과, 102과 220속 322종 2변종 6품종으로 총 330분류군으로 확인되었다. 이중 발표당시의 학명과 현재에 정명으로 정립된 학명과 일치되는 경우는 169분류군으로 51.2%에 불과하였고, 외래식물이 29분류군이 포함된 것이 특징적이었다. 식물 목록 중에는 2000년대 이후 한국 미기록으로 발표된 밤일엽아재비, 털낚시제비꽃, 그늘별꽃, 섬쇠무릎 등의 자생식물뿐만 아니라 외래식물로 1992년에 발표된 주걱개망초 등이 포함된 것으로 나타났다. 또한 아직까지 제주도에서 확인되지 않는 종은 부싯깃고사리등 9분류군이었다. 한국 미기록 종으로 일본, 중국 등에 분포하며 제주도에 분포할 가능성이 있거나 동정에 오류로 보이는 종은 털고사리[Deparia pycnosora (H. Christ) M. Kato]로 추정되는 Deparia acrostichoides (Sw.) M. Kato 등 28분류군으로 판단되 었다. 부종휴에 의해 발표된 제주도 자생식물 목록을 현재의 식물분류체계를 통해 재정립한 결과는 제주도 내 분포하는 종의 실체와 함께 종 분포의 정보를 알리는데 중요한 의미가 있는 것으로 판단된다. This review focuses on 333 scientific names published in 1964 by Jong-Hyu Bu. As a result, a total of 330 taxa including 102 families, 220 genera, 322 species, 2 variants, and 6 varieties were identified. Among them, the percentage of the scientific names at the time of publication corresponding with the accepted names at present accounts for mere 51.2%, 169 taxa including 29 taxa of the alien species. The recently published as unrecorded in Korea, includes native species such as Microsorum buergerianum (Miq.) Ching, Viola grypoceras A. Gray var. pubescens Nakai, Stellaria sessiliflora Y. Yabe, Achyranthes longifolia (Makino) Makino as well as alien species such as Erigeron strigosus Muhl. In addition, the species that have not yet been identified on Jeju Island were 9 taxa including Cheilanthes argenta Kunze. The number of unrecorded species in Korea but distributed in Japan, Chine, etc. amounts to 28 taxa including Deparia acrostichoides (Sw.) M. Kata, which are assumed to inhabit Jeju Island or appear to be in error in identification. The results of re-establishing the list of native plants on Jeju Island announced by Jong-Hyu Bu through the current plant taxonomy are considered to be of high value in forming the knowledge of the species distributed on Jeju Island.

We investigated the flora to study plant distribution characteristics in the craters of Baengnokdam and Dongsuak. The 170 taxa investigated in Baengnokdam crater were composed of 49 families, 124 genera, 169 species and 1 forma, the 180 taxa investigated in Dongsuak crater were composed of 63 families, 135 genera, 179 species, 1 formae. Endemic to Korea or Jeju islands could be seen that there were 28 taxa including Abies koreana in Baengnokdam crater, and 2 taxa including Asarum maculatum in Dongsuak crater. Rare plants could be seen that these were 37 taxa in Baengnokdam crater, 13 taxa in Dongsuak crater. Life form of plants could be seen that phanerophyte took the highest rate which there were 43.6%, 30.1% in Baengnokdam crater and Dongsuak crater respectively, but hydrophyts among the investigated for two wetlands was 2.4%, 9.4% respectively.

한라산 고산식물의 저지대 적응에 관한 연구

고정군,오순자,고석찬 濟州大學校 基礎科學硏究所 2001 基礎科學硏究 Vol.14 No.1

고산식물의 저지대 환경에 대한 적응성을 조사하기 위해 저지대 온실 (150m a.s.l.)에서 고산식물의 생육 및 엽록소형광 특성을 조사하여 자생지 (1,850-1,950m a.s.l.)와 비교하였다. 저지대에서 고산식물의 생장패턴은 유도기가 없이 지수생장기를 거쳐 노화기에 이르렀다. 그리고, 개화기간이 짧고 꽃의 밀도도 낮았으며, 종자발달 기간이 길었다. 관계Ⅱ의 광화학적 효율, 즉 Fv/Fm은 저지대 온실에서 3종 모두 낮시간(12:00-15:00)에 다소 낮아졌으며, Fo의 증가와 Fm의 감소를 동반하여 만성적인 광억제를 야기하는 것으로 판단되었다. 그리고, Fv/Fm은 저지대의 온도와 광량과는 음의 상관을, 상대습도와는 정의 상관을 보였다. 따라서, 저지대 환경에서 고산식물의 적응력을 높이기 위해서는 강한 광선을 차단시키는 것은 물론 생장기간 동안 낮은 온도를 유지시키는 것이 중요한 것으로 해석되었다. The characteristics of growth and chlorophyll fluorescence was studied from three alpine plants ( Tofieldia fauriei, Adenophora taquetii, Chrysanthemum zawadskii ssp. coreanum) from March, 1998 to August, 1999, in order to develop the adaptation of alpine plants to low altitudes. In the low altitude (150m a.s.l.), the growth patterns of alpine plants showed sigmoidal growth curves without lag phase. Flowering periods are shorter while seed development periods are longer, in contrast to them in alpine habitats (1,850-1,950m a.s.l.). The photochemical efficiency of PSII, Fv/Fm, was slightly depressed in midday (12:00-15:00) in low altitude. This midday depression resulted from decrease in Fm combined with increase in Fo, suggesting that alpine plants are chronically photoinhibited in low altitude. The Fv/Fm values of alpine plants under low altitude showed negative relationships with temperature and light intensity, with positive relationships with relative humidity. Therefore, in order to develop the adaptation of alpine plants to low altitudes, it seems to be important to screen the strong light and to keep the temperature low.

N/A Background : Gallbladder (GB) polyps are now increasingly detected by ultrasonography. We investigated the prevalence and risk factors of GB polyps in health screening population. Methods : An ultrasonographic study of GB polyps were conducted in 35,012 subjects who received a paid health screening examination at Samsung Medical Center. Controls, twice the subjects with GB polyp, were randomly selected from the cases with normal GB. The demographic characteristics and biochemical parameters were recorded. Results : The overall prevalence of GB polyps was 2.94% (1,330/15,573). Among them, 3.63% were men, 2.09% were women. In both males and females, the prevalence was highest in their 40s. The diameter of GB polyps ranged from 2 mm to 20 mm (mean 4.5 mm). Most polyps (98.3%) were less than 10 mm in diameter. Of 1,030 subjects, 64% had a single polyp and 36% had multiple polyps. Multiple logistic regression, with reference group of body mass index (BMI, <22.5 kg/m2), showed odds ratio of 1.074 and 1.864 for BMI groups of 22.5-24.9 and 25 or more respectively. In contrast, other demographic characteristics and biochemical parameters, such as age, smoking, alcohol use, glucose, liver function tests, lipid profiles and HBsAg carriage were lack of any relation to GB polyps. Conclusions : GB polyps are not likely to be rare in Korean adults despite their low prevalence compared to other reports. The body mass index may be a risk factor for GB polyps.
