한국산(韓國産) Pinus속(屬)의 Diploxylon아속(亞屬)의 소나무, 중곰솔, 곰솔, 금강소나무에 대(對)한 류별(類別)을 알아보기 위(爲)하여 GLC에 의(依)한 monoterpene 조성(組成)을 분석(分析) 연구(硏究)하여 다음과 같은 결과(結果)를 얻었다. 소나무, 중곰솔, 곰솔, 금강소나무의 monoterpene은 ${\alpha}$-pinene, camphene, ${\beta}$-pinene, myrcene, limonene, ${\beta}$-phellandrene, terpinolene 외(外)에 2개의 미지(未知)의 조성분(組成分)으로 구성(構成)되어 있다. 소나무와 금강소나무의 주요(主要) monoterpene조성(組成)은 ${\alpha}$-pinene, ${\beta}$-phellandrene, myrcene, terpinolene 이다. 중곰솔의 주요(主要) monoterpene 조성(組成)은 ${\beta}$-pinene, ${\beta}$-phellandrene, ${\alpha}$-plnene, terpinolene 이다. 곰솔의 주요(主要) monoterpene 조성(組成)은 ${\beta}$-pinene, ${\alpha}$-pinene, ${\beta}$-phellandrene, limonene 이다. 소나무, 중곰솔, 곰솔, 금강소나무에서 모두 monoterpene 조성분(組成分)은 개체간에 큰 차이(差異)가 있었다. 중곰솔은 monoterpene 조성(組成)에 있어서 소나무와 곰솔의 중간에 해당되었다. 소나무와 곰솔을 구별(區別)하는 가장 좋은 분류적기준(分類的基準)이 되는 monoterpene의 주성분(組成分)은 ${\alpha}$-pinene, ${\beta}$-pinene, myrcene이었고 소나무는 ${\alpha}$-pinene이 ${\beta}$-pinene보다 항상 많았고 중곰솔을 그 반대(反對)였다. 안면도와 치악산(産) 소나무의 산지별(産地別) 차이(差異)에서는 ${\alpha}$-pinene에서 유이성(有異性)이 보였으나 이는 개체 사이의 변이(變異)가 큰 것에 기인(起因)하는 것으로 추측(推測)된다. Monotupenes of the oleoresin of P. densiflora S. et Z., P. densi-thunber gii Uyeki, P. thunbergii Parl., and P. densiflora for. erecta Uyeki of the subgenus Diploxylon of the genus Pinus in Korea were analysed by means of gas liquid chromatography, and following results were obtained. Monoterpene of P. densiflora, P. densi-thunbergii, P. thunbergii, and P. densiflora for. erecta consisted of ${\alpha}$-pinene, camphene, ${\beta}$-pinene, myrcene, limonene, ${\beta}$-phellandrene, terpinolene and two unknown components. Major monoterpene components of P. densiflora and it's for. erecta were ${\alpha}$-pinene, ${\beta}$-phellandrene, myrcene, and terpinolene. Major monoterpene components of P. densi-thunbergii were ${\beta}$-pinene, ${\beta}$-phellandrene, ${\alpha}$-pinene, and terpinolene. Major monoterpene components of P. thunbergii were ${\beta}$-pinene, ${\alpha}$-pinene, ${\beta}$-phellandre, and limonene. Monoterpene components in P. densiflora, P. densi-thunbergii, P. thundergii, and P.densiflora for, erecta showed a range of variation by the individual trees. Monoterpene contents of P. densi-thunbergii were intermediate between those of P. densiflora and P. thunbergii. ${\alpha}$-pinene, ${\beta}$-pinene, and myrcene appeared to be the best taxonomio characteristics for separating P. densiflora from P. thunbergii, and the former had higher content of ${\alpha}$-pinene than ${\beta}$-pinene while those of the latter were vise versa. There was a significant difference of ${\alpha}$-pinene components of P. densiflora between that of Anmyun Island and Mt. Chiak, but it seemed to be caused by the difference of the individual trees rather than provenancial difference.

대덕연구단지의 산림식생은 이차림식생과 조림식생으로 구분되었다. 이차림식생은 소나무군락(Pinus densiflora community)과 상수리나무군락(Quercus acutissima community)으로, 조림식생은 아까시나무군락(Robinia pseudoacacia community), 리기다소나무군락(Pinus rigida community), 곰솔군락(Pinus thunbergii community), 밤나무군락(Castanea crenata community)으로 구분되었다. 본 조사지역에서 출현한 종수는 총 217종이었으며, 각 군락별 평균 출현종수는 소나무군락이 21종, 상수리나무군락 20종, 아까시나무군락 20종, 리기다소나무군락 21종, 곰솔군락 21종, 밤나무군락 18종으로 밤나무군락에서 출현종이 가장 적었고, 이차림군락과 조림군락 간에는 차이가 없었다. 귀화식물은 조사구내에서 닭의장풀, 미국자리공, 개망초, 가중나무 등 12종이 출현하였고, 등산로와 산림주변부에서는 오리새, 미국가막사리, 도꼬마리, 까마중 등 19종이 출현하여 총31종의 귀화식물이 조사되었다. The forest vegetation in Daedeok Science Town were classified as second forest vegetation and afforestation vegetation. The second forest vegetation was classified into two communities such as Pinus densiflora community and Quercus acutissima community. Also, the afforestation vegetation was classified again as Robinia pseudoacacia community, Pinus rigida community, Pinus thunbergii community, and Castanea crenata community. In this study area, we found total 217 taxa. The average species of appearance in Pinus densiflora community, Quercus acutissima community, Robinia pseudoacacia community, Pinus rigida community, Pinus thunbergii community, and Castanea crenata community were 21, 20, 20, 21, 21, and 18, respectively. There was no difference in appearance species between second forest and afforestation vegetation. We found total 12 naturalized plants taxa of Commelina communis, Phytolacca americana, Erigeron annuus, and Ailanthus altissima in the plots and total 19 naturalized plants taxa of Dactylis glomerata, Bidens frondosa, Xanthium strumarium, and Soianum nigrum in the climbing roads and forest circumferences. And so, we found total 31 naturalized plants taxa in this study area.

Vegetational data from Mt. Gyeryong and Deokyu in central Korea were analysed in relation to 15 environmental variables. Two multivariate methods were applied : two-way indicator species analysis (TWINSPAN) for classification and detrended canonical correspondence analysis(DCCA), a recent technique which extracts ordination axes that can be related to environmental factors. The relationship between the distribution of dominant species of forest vegetation and soil condition in blt. Gyeryong and Deokyu was investigated by analyzing elevation and soil nutrition gradient. Quercus mongolica forest was distributed in the high elevation and good nutrition area, Carpinzrs laxiflora and Fraxinus rhynclzophylla forest in the medium elevation and good nutrition area, Piszus densiflora-Quercus mongolica and Quercus variabilis forest in the medium elevation and medium nutrition area, Styrax jabozaica forest in the low elevation and medium nutrition area, and Pinus densiflora forest in the low elevation and poor nutrition area. The dominant compositional gradient related to elevation.

모르핀 정맥 투여시 척수 진통 작용 기전에 기여하는 Nitric Oxide

N/A Background: The role of nitric oxide(NO) in analgesia from opioids is controversial. On the one hand, IV morphine analgesia is enhanced by IV injection of NO synthase inhibitors. On the other hand, IV morphine results in increased release of NO in the spinal cord. There have been no behavioral studies examining the interaction between IV morphine and intrathecal injection of drugs which affect NO synthesis. Method: Rats were prepared with chronic lumbar intrathecal catheters and were tested withdrawal latency on the hot plate after 3-5 days of surgery. Antinociception was determinined in response to a heat stimulus to the hind paw before and after IV injection of mqrphine, 2.5 mg/kg. Twenty minutes after morphine injection, rats received intrathecal injection of saline or the NO synthase inhibitors, L-NMMA or TRIM, the NO scavenger, PTIO, or the NO synthase substrate, L-Arginine. Intrathecal injections, separated by 15 min, were made in each rats and measurements were obtained every 5 min. Result: Mophine produced a 60-70% maximal antinociceptive response to a heat stimulus in all animals for 60 min in control experiments. Intrathecal injection of idazoxane decreased antinociception of IV morphine. The NO synthase inhibitors and the NO scavenger produced dose-dependent decreases in antinociceptive effect of morphine, whereas saline as a control group and L-Arginine as the NO substrate had no effect on antinociception of morphine, Conclusion: The present study supports the evidences that systemic morphine increase the nitrite in cerebrospinal fluid and dorsal horn. These data suggest that the synthesis of NO in the spinal cord may be important to the analgesic effect of IV morphine and increased NO in spinal cord has different action from the supraspinal NO

N/A This study was carried out to provide basic data for establishment of Natural Ecology Center through vegetation research in Nodong valley, Pyungchanggun of Kangwondo. The vascular plants consisted of total 178 taxa such as 56 families, 121 genera, 152 species, 24 varieties and two forms. In the study area, we found some plants designated as protect plants by the Ministry of Environment such as Dryopteris crassirhizoma and Rodgersia podophylla that is a vulnerable species and Iris odaesanensis that is an endemic specis. COmmunities by characteristic in species composition of Nodong valley forest were classified into Quercus mongolica-Acer pseudosieboldianum community as a natural forest community and Larix leptolepis and Pinus koraiensis community as artificial forest. The Quercus mongolica-Acer pseudosieboldianum community was further classified as Pinus densiflora subcommunity and Acer mono subcommunity. A protection program will be needed for Iris odaesanensis classified as an endemic species to make a Natural Ecology Center.

Vegetational data obtained from 50 quadrats of Mt. Jungwangsan area were analysed by applying two multivariate methods : two-way indicator species analysis(TWINSPAN) for classification and detrended canonical correspondence analysis(DCCA) for ordination. DCCA technique allowed to extract the ordination axes that could be related to 15 environmental factors. The forest vegetation in Mt. Jungwangsan was classified into Quercus mongolica-Tilia amurensis, Quercus mongolica-Rhododendron schlippenbachii, Quencus mongolica-Kalopanax pious, Quercus mongolica-Carpinus cordata, Quercus mongolica-Cornus controversa, Betula costata, Fraxinus mandshurica, and Ulmus laciniata communities according to the TWINSPAN. The relationships between the distribution of dominant species of forest vegetation and soil condition in Mt. Jungwangsan were investigated by analyzing elevation and soil nutrition gradient. Ulmus laciniata, Betula costata, and Frazinus mandshurica forest were distributed in a ravine of the low elevation and in the good nutrition area of Mg^(++), total nitrogen, and Ca^(++), Quercus mongolica groups in the high elevation and in the poor nutrition area. Quercus mongolica-Kalopanax pious forest of Quercus mongolica groups was distributed in the high elevation and in the good nutrition area of Ca^(++), C.E.C., Mg^(++), and total nitrogen, Quercus mongolica-Rhododendron schlippenbachii forest in the low elevation and poor nutrition area. Quercus mongolica-Carpinus cordata forest and Quercus mongolica-Cornus controversy forest were distributed in the medium elevation and medium nutrition area. The two dominant factors influencing community distribution were elevation and topography.
