  • This study was peformed to evaluate antithrombotic activities and anti-inflammatory effects of Kami-BoyangHwanoh-Tang(KBHT). The major findings were summarized as follows. In experiment of anti-thrombotic effect; KBHT inhibited human platelet aggregation induced by ADP and epinephrine as compared with the control group and inhibited pulmonary embolism induced by collagen and epinephrine (inhibitory rate is 50 %). KBHT increased platelet number significantly and also KBHT shortened PT and APTT significantly as compared with the control group in thrombus model induced by dextran. In experiment of anti-inflammatory effect; KBHT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression as compared with the control group in a concentration-dependent degree, and inhibited NO production significantly at 50, $100\;{\mu}g/^{ml}$, and also inhibited ROS production in a concentration-dependent degree as compared with the control group in RAW 264.7 cell line. KBHT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, and also decreased IL-6 and $TNF-{\alpha}$ production in liver tissue, but increased $IL-1{\beta}$ production in liver tissue of acute inflammation-induced mice. KBHT increased survival rate at 3rd day in mice with lethal endotoxemia induced by LPS. These results suggest that KBHT can be useful in treating diverse female diseases caused by thrombosis and inflammation such as endometrosis, myoma, pelvic congestion, chronic cervicitis, chronic pelvic inflammatory disease and so on.

  • Silsosangami(SSG) is a formula of oriental medicines as an effective biological response modifier for augmenting host homeostasis of body circulation. Also SSG has been known to have an anti-diabetic activity and anti-platelet aggregation activity. The present study was undertaken to examine the effects of a new SSG on murine macrophage and human neutrophil functions as well as on several enzymes relevant to the inflammatory process. The results of the present study indicate that SSG exerts anti-inflammatory effects related to the inhibition of neutrophil functions and of PGE2 production, which could be due to a decreased expression of and COX-2.

  • Purpose: In this study, we investigated the anti-thrombotic and antiinflammatory efficacy of "Gamijoukyungtang(GJKT)". Methods: We studied inhibitory effects of platelet aggregation, FXa activation, $TXB_2$ and $PGE_2$ biosynthesis and suppressive effects of GPIIb/IIIa activity and oxidative damage, pro-inflammatory cytokine reduction effects of 'GJKT(by press extractor)/GJKT-1(by pressless extractor)' in vitro. Also, we studied suppression of pulmonary embolism, AV shunt model in rats and shortening of Rat tail bleeding time in vivo. Results: GJKT/GJKT-1 extract showed inhibitory effects on GPIIb/IIIaactivities and platelet aggregation induced by ADP, epinephrine, collagen and arachidonic acid. They suppressed biosynthesis of $PGE_2$ but GJKT-1 only supressed biosynthesis of $TXB_2$. In FXa assay, they inhibited activation of FXa. they suppressed pulmonary embolism triggered by collagen and epinephrine. In AV shunt model, they decreased the weights of AV shunt thrombus. they inhibited pro-inflammatory cytokines and decreased oxidative damages caused by DPPH. Conclusion: We confirmed the anti-thrombosis, and ant-inflammatory efficacy of 'GJKT(by press extractor)/GJKT-1(by pressless extractor)'.

  • The leaf extract of Ligularia stenocephala showed the highest anti-platelet aggregating activity in large numbers of edible and herbal plants. The active fraction fractionationed from L. stenocephala extract by using preparative HPLC inhibited the platelet aggregation up to above 80% and its blood coagulating time (PT and APTT) also showed similar effect to aspirin (0.2 ${\mu}g/mL$), known as an anti-thrombus compound. Two antithrombus active compounds were purified and identified as 3,5-dicaffeoylquinic acid and 3,4-dicaffeoylquinic acid, respectively, on the basis of NMR and FAB-MS spectroscopic data. Two active compounds has not only antiplatelet aggregating activity, but also has anticoagulating activity.

  • Flavonoid glycosides were metabolized to phenolic acids via aglycones by human intestinal microflora producing ${\alpha}$-rhamnosidase, exo-${\beta}$-glucosidase, endo- ${\beta}$-glucosidase and/or ${\beta}$-glucuronidase. Rutin, hesperidin, naringin and poncirin were transformed to their aglycones by the bacteria producing ${\alpha}$-rhamnosidase and ${\beta}$-glucosidase or endo- ${\beta}$-glucosidase, and baicatin, puerarin and daidzin were transformed to their aglycones by the bacteria producing ${\beta}$glucuronidase, C-glycosidase and ${\beta}$-glycosidase, respectively. Anti-platelet activity and cytotoxicity of the metabolites of flavonoid glycosides by human intestinal bacteria were more effective than those of the parental compounds. 3,4-Dihydroxyphenylacetic acid and 4-hydroxyl-phenylacetic acid were more effective than rutin and quercetin on anti-platelet aggregation activity. 2,4,6-Trihydroxybenzaidehyde, quercetin and ponciretin were more effective than rutin and ponciretin on the cytotoxicity for tumor cell lines. We insist that these flavonoid glycosides should be natural prodrugs.

  • There is currently increased interest in the identification of antioxidant compounds that are pharmacologically potent and have low or no side effects. Plants produce significant amounts of antioxidants to prevent the oxidative stress caused by photons and oxygen, therefore they represent a potential source of new compounds with antioxidant activity. Moutan Root Sark (MRS) has been frequently used as analgesic. antispasmodic, anti-inflammatory and remedies for female diseases. In this study. the antioxidant activity of extract from MRS was studied in vitro methods by measuring the antioxidant activity by TEAC, measuring the scavenging effects on reactive oxygen species (ROS) [superoxide anion, hydroxyl radical] and on reactive nitrogen species (RNS) [nitric oxide and peroxynitrite] as well as measuring the inhibitory effect on $Cu^{2+}$ induced human LDL oxidation and the inhibitory effect on collagen induced platelet aggregation. The MRS extracts were found to have a potent scavenging activity, as well as an inhibitory effect on LDL oxidation and on platelet aggregation. In conclusion, the MRS extracts have anti-oxidative and anti-atherosclerotic effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and atherosclerosis.

  • 현대사회는 고지방의 서구화된 식사, 과도한 스트레스 등으로 비정상적인 혈액응고 및 과다한 혈소판 응집이 증가되고 있으며, 이로 인한 다양한 혈전성 질환 위험성도 증가되고 있다. 본 연구에서는 제주 특용식물인 상동나무(Sageretia thea) 지상부의 항혈전 활성을 평가하기 위해 잎(ST-L), 줄기(ST-B), 열매(ST-F) 에탄올 추출물을 조제하고 이의 항혈전 활성, 인간 적혈구 용혈활성 및 flavonoids·phenolic acids 조성을 검토하였다. ST-B 추출물은 식용으로 이용되고 있는 ST-F 추출물보다 6.7배의 총 폴리페놀 함량을 보였으며, ST-L 추출물은 ST-F 추출물보다 2.7배 높은 총 플라보노이드 함량을 보였다. 혈액응고 저해활성 평가 결과, ST-F 추출물은 aPTT에서만 혈액응고시간 연장이 미약하게 나타났으나, ST-L 및 ST-B 추출물은 기존 항혈전제인 aspirin 및 베리류 및 한방 약재 추출물보다 트롬빈, 프로트롬빈, 응고인자들에 대해 강력한 저해활성을 나타내었다. 혈소판 응집저해 역시 ST-L 및 ST-B 추출물은 aspirin보다 우수한 응집저해 활성을 나타내었으며, 인간 적혈구에 대한 용혈활성은 1 mg/ml 농도까지 전혀 나타나지 않았다. ST-L 및 ST-B 추출물의 phenolic acid 및 flavonoids 분석결과, rutin, isoquercitrin 및 astragalin이 주요 활성물질로 확인되었다. 본 연구결과는 상동나무 잎과 줄기의 강력한 항혈전 활성의 최초 보고이며, 상동나무를 이용한 항혈전제 개발이 가능함을 제시하고 있다. 향후 상동나무에서 처음으로 확인된 isoquercitrin의 항혈전 기전에 대한 연구가 필요하다.

  • 도토리 화분은 국내에서 가장 많이 생산되는 단일 화분으로, 민간에서는 지혈, 빈혈방지, 전립선염 치료 등에 이용되어 왔다. 본 연구에서는 식물 화분을 이용한 기능성 식의약품 소재 개발 가능성을 검토하고자, 도토리 화분의 에탄올 추출물의 극성별 유기용매 분획물을 제조하고 이의 성분 분석, 항산화, 항응고, 혈소판 응집 저해활성 및 활성 분획물의 적혈구 용혈 활성을 평가하였다. 총 폴리페놀 함량은 도토리 화분 에탄올 추출물 중 에틸아세테이트 분획물에서 가장 높은 225.0 mg/g을 나타내었다. 상기 에틸아세테이트 분획은 DPPH, ABTS 및 nitrite에 대한 RC50값이 각각 72.2, 27.7 및 62.6 ㎍/ml를 나타내어 강력한 항산화 활성을 보였다. 한편 도토리 화분의 항혈전 활성 평가를 위해 혈액응고저해 활성 평가 결과, 모든 분획물에서 5 mg/ml 농도까지 특이한 항응고 활성은 나타나지 않았다. 반면 혈소판 응집저해활성 평가 결과, 도토리 화분 추출물의 에틸아세테이트 분획물, 부탄올 분획물 및 물 잔류물에서 우수한 응집저해가 나타났으나, 헥산 분획물에서는 오히려 응집촉진 효과를 나타내었다. 항산화 활성 및 혈소판 응집 저해활성이 우수한 도토리 화분 추출물의 에틸아세테이트 분획물은 1 mg/ml 농도까지 인간 적혈구 용혈활성이 없었으며, UPLC/MS/MS 분석결과 rutin, isoquercitrin 및 astragalin이 주요 활성물질임을 확인하였다. 본 연구는 도토리 화분 추출물의 에틸아세테이트 분획물을 이용한 새로운 항산화 및 항혈전제로 개발이 가능함을 제시하고 있다.

  • 열대마로 알려진 Dioscorea alata L.는 전 세계 650여종의 마 중에서도 가장 많이 소비되고 있으며, 적도, 아적도 지역에서 광범위하게 재배하고 있다. 실제 중국과 인도에서는 주요 식용자원 및 약용으로 이용되고 있다. 최근 국내에서는 기존의 단마 및 장마에 비해 2배 이상 높은 수확량을 나타내는 열대마 재배가 증가하고 있으며, 열대마에 높은 관심이 집중되고 있다. 그러나 현재까지 열대마의 주아(영여자)에 대한 연구는 전무한 실정이다. 본 연구에서는 국내 단마 및 열대마 영여자의 에탄올 추출물을 조제하여, 단마 영여자와 비교하여 열대마 영여자의 영양특성 및 추출물의 항혈전 활성을 평가하였다. 그 결과, 열대마 영여자는 특유의 황색과 함께 영양적으로 우수하며, 단마 영여자와는 달리, 열대마 영여자 추출물은 1.25 mg/ml 농도에서 아스피린보다 우수한 트롬빈, 프로트롬빈 및 혈액응고인자 저해를 나타내어 강력한 항응고 활성을 나타냄과 동시에 혈소판 응집저해 활성도 우수하였다. 또한 열대마 영여자 추출물은 2.5 mg/ml 농도까지 인간 적혈구에 대한 용혈활성도 전혀 나타나지 않았다. 이러한 결과는, 열대마 영여자가 새로운 항혈전 소재로 개발 가능함을 제시하고 있다.
