Objectives : Siegesbeckiae Herba's effect on the protection of nerve cells was tested, and the effects were compared between Siegesbeckia glabrescens Makino, the state of which is spica imported from China, and original Korean leaves of it. Methods : After damaging nerve cells by exposing them on NMDA (N-methyl-D-aspartic acid) and KA(kainic acid), Siegesbeckiae Herba's effect on cell death, inhibition rate, glutamate separation, and ROS(reactive oxygen species) production were examined. Results : 1. Siegesbeckiae Herba inhibited the cell death exposed to NMDA. 2. Siegesbeckiae Herba inhibited the amount of glutamate separated from nerve cells exposed to NMDA. 3. Siegesbeckiae Herba inhibited the production of ROS induced by NMDA. 4. Siegesbeckiae Herba did not inhibit the cell death exposed to KA. 5. Chinese Siegesbeckiae Spica had no inhibition effect on cell death. Conclusions : Siegesbeckiae Herba was effective in inhibiting the death of nerve cells exposed to NMDA, and in protecting nerve cells from various damages in nerve cell diseases. Because Chinese Siegesbeckiae Spica did not show such effects, it is necessary to closely examine those effects according to the used parts.

This study was undertaken to define the mechanism of Siegesbeckiae Herba-induced relaxation in rabbit common carotid artery contracted by agonists. In order to investigate the effect of Siegesbeckiae Herba on contracted rabbit carotid arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. To analyze the mechanism of Siegesbeckiae Herba-induced relaxation, Siegesbeckiae Herba extract infused into contracted arterial strips induced by agonists after treatment of lanthanum chloride, indomethacin, atropine, $N\omega-nitro-{_L}-arginine$, cobalt chloride or methylene blue. The relaxation effect of Siegesbeckiae Herba was dependent on the presence of endothelium, showing that Siegesbeckiae Herba-induced relaxation was not observed in the strips without endothelium. The endothelium-dependent relaxation induced by Siegesbeckiae Herba was suppressed by the pretreatment of lanthanum chloride, $N\omega-nitro-{_L}-arginine$, cobalt chloride or methylene blue, but it was not observed in the strips pretreated with indomethacin or atropine. These results demonstrated that Siegesbeckiae Herba may inhibit agonist-induced contraction through an increase in the cyclic GMP by the production of nitric oxide in the vascular endothelial cells.

Many diterpenoids from Siegesbeckia species (Compositae) and their anti-inflammatory actions have been examined. In this research, high-performance liquid chromatography-ultraviolet spectrophotometer (HPLC-UV) method was used to compare the quantitative level of kirenol (ent-pimarane-type diterpenoid) in the aerial parts of Korean S. glabrescens and S. pubescens and the Chinese Siegesbeckiae Herba. Fingerprints of the two HPLC chromatograms of Korean S. glabrescens and S. pubescens were similar, but considerably different from Chinese Siegesbeckiae Herba. The content of kirenol in S. pubescens ($16.51{\pm}0.10$ mg/ml dry weight as mean${\pm}$RSD) was higher than S. glabrescens ($13.48{\pm}0.12$ mg/g dry weight). These values were considerably higher than the Chinese Siegesbeckiae Herba ($1.55{\pm}0.74$ mg/g dry weight). Thin layer chromatography (TLC) analysis demonstrated the containing of kirenol in the three plant materials, but the presence of siegeskaurolic acid (entkaurane-type diterpenoid) only in the Chinese Siegesbeckiae Herba.

In order to investigate the effect of the Herba Segesbeckiae on the thrombosis induced by endotoxin in rats. The rats were treated with solid extract of Herba Siegesbeckiae 41.9mg /200g(Sample) which were administered orally. And the thrombosis was induced by injecting endotoxin in the caudal vein rats. And then the number of platelets, concentration of fibrinogen, prothrombin time and FDP(fibrinogen degradation product) were measured. The results were as follows; 1. Platelet was increased significantly in sample group compared with control group. 2. Prothrombin time was shortened significantly in sample group compared with control group. 3. Fibrinogen was increased significantly in sample group compared with control group. 4. FDP was decreased significantly in sample group compared with control group. According to the above results, Herba Siegesbeckiae had significant effects on number of Platelets, Prothrombin time, Fibrinogen and FDP. therefore, it is considered that Herba Siegesbeckiae can be applied to diseases related to thrombosis.

희첨 Siegesbeckiae Herba 의 축추물(수성및 알콜성)을 가토의 정맥내에 투여할때 일과성이 긴 하나 현저한 혈압강하작용이 나타나며 이들의 혈압강하작용은 atropoine이나 diphenhydramine에 의하여 유의성인 억제가 이루어짐을 저자들은 발표한바 있다. 그러나 벨라도나 알칼로이드가 개및 고양이에서는 심전 증가를 일으키거나 가토에서는 그렇지를 못하는것처럼 동물의 종에 따라 약물의 반응이 상이한 경우가 있다. 따라서 이 희첨의 실용성 여부를 정확히 파악하기 위한 실험의 한 방법으로서 실험 동물의 종차에 따른 혈압강하작용및 그 기전에 있어서 차이점의 유무를 확인하고저 비교적 작용강도가 큰 비의 에탄올 엑기스로 개및 닭을 이용하여 이번 실험을 시행하였다.

희첨(Siegesbeckiae Herba)은 진득찰(Siegesbeckiae pubescens Makino)의 잎을 말하며 한방에서 중풍, 전신마비, 반신불수, 부종등에 사용되어 왔다. 이에 관한 연구로는 한등이 diterpene계의 불합물을 분리하였고 이 diterpene계중의 한 성분이 실험적 신성 고혈압을 유기한 백서에 항고혈압작용이 있음을 보고한바 있으나 이의 고혈압 활료제로의 실용성 여부에 관하여서는 확인된 바가 없어 고혈압 치료제 개발의 일환으로서 화학적 성분 연구에 우선하여 약리학적으로 그 본태를 파악하고저 수성 및 알콜성 엑기스를 축출하여 가토에 대하여 이 실험을 시행하였다.

For evaluating the effect of Siegesbeckiae Herba (here after abbreviated as SBH) on rheumatoid arthritis, the experiment was carried out; Incidence of rheumatoid arthritis, IRA(indices of rheumatoid arthritis), immunophenotypes by flow cytometer and histopathological changes in MRL/MpJ-Ipr-Ipr Mice in vivo were studied. The results were obtained as follows: 1. Incidence of RA in MRL/Ipr mice was suppressed to 60% of control by SBH. 2. IRA was significantly reduced for IgG3 and IgM at 20 weeks of age and for IgG2b at 12 and 20 weeks of age in mice by SBH compared with control. 3. Immunophenotypes such as CD4/sup +//CD25/sup +/, CD8/sup +//CD3e/sup +/, CD69/sup +//B220/sup +/, NK/sup +//CD3e/sup +/ were significantly increased by SBH compared with control. 4. In histopathological analysis, SBH suppressed the progression of PMN(polymorphonuciear leukocyte), leukocyte and fibroblast infiltration, and subsynovial soft tissue edema frequently showing in the early stage of the arthritis, and also effectively reduced the degeneration of cartilages and degenerative bone symptoms. These results suggest Siegesbeckiae Herba can be effectively applied to the treatment of rheumatoid arthritis and it is still necessary to isolate effective compound from Siegesbeckiae Herba in the near future.

본 연구에서는 신생혈관형성 제어에 바탕을 둔 비만세포제어 정도를 확인하기 위하여 4가지 지역 천연산물인 전호(Anthrisci radix), 파고지 (Psoraleae semen), 희첨 (Siegesbeckiae herba) 및 산수유 (Corni fructus)를 이용한 지방 축적물 변화 및 기전을 확인하기 위해 3T3-L1 adipocyte를 이용한 Oil Red O 염색 및 western blot을 실시하였다. 그 결과 전호, 파고지, 희첨, 산수유의 세포 독성 이내의 농도 증가에 따라 지방 축적물이 감소됨을 보였다. 또한 western blot을 위해 lipogenesis와 관련된 SREBP-1 및 adipogenesis와 관련된 $PPAR\gamma$와 C/$EBP\alpha$의 신호전달 정도를 확인한 결과 4가지 지역 천연산물의 농도 증가에 따라 단백질의 발현양이 감소됨을 확인하였다. 이는 4가지 지역 천연산물 추출물이 지방분화와 관련된 신호분자를 차단함으로써 지방형성이 억제되었음을 보였다. 따라서 4가지 지역 천연산물인 전호, 파고지, 희첨 및 산수유는 신생혈관형성 억제에 따른 항비만제제로서의 이용 가능함을 시사하였다.

A study on the diuretic action of Siegesbeckiae herba in dogs was made using a clearance technique with ethanol extract. Siegesbeckiae herba ethanol extract (SGEE) administered intravenously in doses 6.0 and 60.0mg/kg elicited diuresis and an increase in sodium and potassium excretion, and it simultaneously produced a decrease in the reabsorption rate of sodium and potassium in renal tubules. Neither renal plasma flow nor glomerular filtration rate changed significantly. SGEE, when infused directly into a renal artery in doses of 0.5 and 1.5mg/kg min, exhibited identical results to the intravenous responses confined only to the infused kidney. The above observations lead to the suggestion that SGEE elicits diuresis in dogs by decreasing the reabsorption rates of sodium and potassium in renal tubles.
