여운홍,김호현 世明대학교 한의학연구소 2004 韓醫學硏究所 論文集 Vol.6 No.-
This study was undertaken to define the effect of DaeSiHoTang on the norepinephrine-induced arterial contraction and the mechanism of DaeSiHoTang induced relaxation. In order to investigate the effect of DaeSiHoTang on contracted rabbit carotid Arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. To analyzed the mechanism of DaeSiHoTang-induced relaxation. DaeSiHoTang extract infused into contracted arterial strips induced by norepinephrine after treatment of indomethacin, N_(ω)-nitro-L-arginine, or tetraethylammonium chloride. DaeSiHoTang relax arterial strip with endothelium contracted by norepinephrine, but in the strips without endothelium, DaeSiHoTang-induced relaxation was significantly inhibited. The endothelium-dependent relaxation induced by DaeSiHoTang was decreased by the pretreatment of N_(ω)-nitro-L-arginine, but it was not observed in the strips pretreated with indomethacin or tetraethylammonium chloride. We suggest that DaeSiHoTang may directly suppress influx of extra-cellular Ca^(++) and indirectly suppress influx of extra-cellular Ca^(++) through the formation of nitric oxide in the vascular endothelial cells.

This study was undertaken to define the effect of DaeSiHo-Tang extract on the hypertension in spontaneous hypertensive rat and norepinephrine-induced arterial contraction in rabbit. Systolic blood pressure and blood velocity were significantly attenuated by administration of DaeSiHo-Tang extract. but blood flow and renin-angiotensin-aldosterone system unaffected by DaeSiHo-Tang extract. The relaxation effect of DaeSiHo-Tang extract was dependent on the presence of endothelium, showing that DaeSiHo-Tang extract-induced relaxation was not observed in the strips without endothelium. The endothelium-dependent relaxation induced by DaeSiHo-Tang extract was decreased by the pretreatment of Nω-nitro-L-arginine or methylene blue, but it was not observed in the strips pretreated with indomethacin or tetraethylammonium chloride. When Ca²⁺ was applied, the strips which were contracted by norepinephrine in a Ca²⁺-free solution, arterial contraction was increased. But pre-treatment of DaeSiHo-Tang extract inhibited contractile response to Ca²⁺. These results indicate that antihypertensive effect of DaeSiHo-Tang extract is due to descend arterial resistance by the arterial relaxation through the formation of nitric oxide in the vascular endothelial cells.

오동나무애매미충 ( 가칭 ) (假稱) 에 의한 오동나무빗자루병의 일일초로의 충매전염 (蟲媒傳染)
여운홍(Woon Hong Yeo),박원철(Won Chull Bak),이재호(Jae Ho Lee),고명균(Myung Gyoon Koh),이창근(Chang Keun Yi),김영호(Young Ho Kim) 한국산림과학회 1994 한국산림과학회지 Vol.83 No.1
Sixteen kinds of piercing-sucking mouth type insects were observed at witches`-broom diseased paulownia (Paulownia tomentosa) trees. Among ten insect species tested, a leafhopper, Empoasca sp., transmitted paulownia witches`-broom mycoplasma-like organism(PWB-MLO) to periwinkle(Catharanthus noseus) plant. Adults of this leafhopper were collected from PWB-diseased paulownia trees. The leafhpoppers were allowed to feed on the PWB-infected paulownia trees for three weeks to acquire PWB-MLO. These insects were then transferred to healthy seedlings of paulownia and periwinkle plants for inoculation-feeding. About 30-40days after the inoculation, $quot;little-leaf$quot; symptoms developed on periwinkle plants, but no symptoms developed on paulownia seedlings. MLO infection in the diseased periwinkle tissue was diagnosed by fluorescence microscopy. MLOs were observed in the sieve tubes by electron microscopy, proving the insect transmission of PWB-MLO.

이창근,여운홍,나용준 한국임학회 1980 한국산림과학회지 Vol.47 No.1
林木育種硏究所 포플러 採穗圃에 植栽되어 있는 포플러 (P. deltolides) 中 外觀上 모자이크 病徵이 뚜렷한 잎을 1979年 10月 11일에 採取하여 病斑部位의 汁液을 2% P.T.A (phosphotungstic Acid)로 negative 染色하여 電子顯微鏡으로 檢鏡한 結果 간이 640 ㎛ (200∼1,300 ㎛의 系狀바이러스 粒子가 多數 觀察되었다. 觀察된 바이러스 크기의 粒子의 크기는 歐美地域에서 報告된 포플러모자이크 바이러스 粒子의 크기와 一致하였다.

제초제처리에 (除草劑處理) 의한 잣나무털녹병 중간기주 ( 송이풀류 ) 제거시험
이창근,김현중,여운홍 ( Chang Keun Yi,Hyun Joong Kim,Woon Hong Yeo ) 한국산림과학회 1981 한국산림과학회지 Vol.51 No.1
The study was conducted during 1975-1980 to evaluate the performance of several herbicides in controling alternate host, Pedicularis spp., of white pine blister rust disease in forest stands. The results obtained were summarized as follows. 1. It was found that Roundup was effective and most suitable herbicide in the fosest stands except that it accompanied some chemical injuries to neighboring plants. 2. As for the reduction density on the plot treated with Roundup was 100% and 65-91% respectively when investigated one and two years after its treatment on Pedicularis spp. 3. Another four chemicals, 2.4-D, Gramoxone, 2.4. 5-T and Para-col killed stems and leaves of Pedicularis spp. at the year treated, but appeared again next spring. 4. Eradication effectiveness in terms of spraying season was proved to be that late August was better than late May or June.

버즘나무를 가해하는 우리나라 미기록 해충이 발생되어 동정한 결과 버즘나무방패벌레(신칭)로 확인되었다. 성충은 체장이 3.0~3.2mm이며 외견상 유백색을 띠고 있고 노숙약충은 검은색을 띠고 있다. 버즘나무의 잎 뒷면에 모여 흡즙 가해하며 피해엽은 황백색으로 변한다. 본 해충은 1995년 9월말 현재 서울, 경기, 강원, 충북, 충남 등 중부지방에 분포하고 있는 것으로 나타났다. The sycamore lace bug, Corythucha ciliata (Say), attacking a sycamore tree, Platatanus orientalis L., was first found in Korea, and was widely distributed in the central part of the country. The adult was milky white in color and 3.0-3.2 mm long, and the matured nymph was black. Heavily infested trees appear yellowish white as a result of feeding by the nymphs on the under surface of leaves.
