In this study, we compared antithrombotic activities of Korean Red Ginseng (KRG) and Cervi Parvum Cornu (CPC) on rats with induced thrombosis. Results indicate that KRG and CPC suppressed the arterial occlusion and the combination of KRG and CPC (KRG + CPC) treatment exhibited a synergistic effect with maximum reduction in thrombosis.

국내 전통주의 품질 우수성 및 유용 생리활성을 확인하기 위해, 시판 전통주의 이화학적인 성분들을 분석하고, 알코올을 제거한 전통주 농축액의 항균 활성, 항산화 활성 및 트롬빈 저해에 따른 항혈전 활성을 평가하였다. 국내의 시판 탁주($T1{\sim}T3$), 약주썬주($Y-l{\sim}Y-5$), 과실주(F-1) 및 소주(S-1, S-2)를 대상으로 성분 분석 결과, 사용된 발효기질 및 첨가된 약용식물에 따라 차이를 나타내었으나, 전반적으로 Y-3, Y-4, Y-5 및 F-1에서 높은 함량의 환원당, 총 폴리페놀, 총 플라보노이드 함량을 나타내었다. 또한 유용 생리활성 활성을 평가한 결과 Y-3, Y-4, Y-5 및 F-1에서 강력한 항세균 활성과 항혈전 활성을 나타내었으며, DPPH 소거능은 F-1에서만 미약하게 확인되었다. 특히 항세균 활성의 경우 기존 항생제에 내성을 나타내는 균주에 대해서도 우수한 활성을 나타내었으며, 그람 양성 및 음성세균 모두에 저해활성을 나타내었다. Y-3, Y-4, Y-5 및 F-1 전통주 농축액의 유기용매를 이용한 순차적 활성분획 결과, 항균 및 항혈전 활성이 모두 ethyl acetate 분획물에서 확인되었으며, 특히 항혈전 활성의 경우 Y-3, Y-4 및 F-1에서는 aspirin보다 더욱 강력한 트롬빈 저해를 나타내었다. 본 연구결과는 전통주의 발효과정 중 첨가한 발효기질 및 약용식물로부터 다양한 물질이 용출, 생성 및 수식되어 유용 생리활성을 제공할 수 있음을 나타내며, 국내 전통주로부터 다양한 생리활성물질의 생산도 가능함을 제시하고 있다.

Platelet anti-aggregating activities were tested with analogs of protocatechuic acid and gallic acid. Six of them which showed comparable inhibitory effects with aspirin against collagen induced platelet aggregation were selected and their anti-thrombotic effects were evaluated in the mouse thrombosis model and compared with those of aspirin and paeonol. At the dose of 50 mg/kg, p.o., ethyl gailate(13) treated group showed higher % of recovery within 6 min of thrombotic challenge and lower mortality within 5 min than aspirin treated group.

Arterial thrombosis and its associated diseases are considered to constitute a major healthcare problem. Arterial thrombosis, defined as blood clot formation in an artery that interrupts blood circulation, is associated with many cardiovascular diseases. Oxidative stress is one of many important factors that aggravates the pathophysiological process of arterial thrombosis. Apurinic/apyrimidinic endonuclease 1/redox factor-1 (Ref-1) has a multifunctional role in cells that includes the regulation of oxidative stress and anti-inflammatory function. The aim of this study was to investigate the therapeutic effect of adenovirus-mediated Ref-1 overexpression on arterial thrombosis induced by 60% FeCl3 solution in rats. Blood flow was measured to detect the time to occlusion, thrombus formation was detected by hematoxylin and eosin staining, reactive oxygen species (ROS) levels were detected by high-performance liquid chromatography, and the expression of tissue factor and other proteins was detected by Western blot. FeCl3 aggravated thrombus formation in carotid arteries and reduced the time to artery occlusion. Ref-1 significantly delayed arterial obstruction via the inhibition of thrombus formation, especially by downregulating tissue factor expression through the Akt-GSK3β-NF-κB signaling pathway. Ref1 also reduced the expression of vascular inflammation markers ICAM-1 and VCAM-1, and reduced the level of ROS that contributed to thrombus formation. The results showed that adenovirus-mediated Ref-1 overexpression reduced thrombus formation in the rat carotid artery. In summary, Ref-1 overexpression had anti-thrombotic effects in a carotid artery thrombosis model and could be a target for the treatment of arterial thrombosis.

According to the Chinese and Korean medicinal and herbal literature, SSG(Silsosangami) is effective for the treatment of inflammation, hyperlipemia and arteriosclerosis. The pharmacological action of SSG has been limitedly studied in regard to ischemic infarction. This herbal medicine has been shown to express diverse activities such as immunomodulating, anti-infarction, anti-allergic and anti-inflammatory effects. Antisclerotic effects of SSG in experimentally induced atherosclerosis in rabbits have also been reported. However, pharmacological mechanisms of SSG on lipid metabolism and atherosclerosis formation are poorly understood. The present paper reports the effect of extracts obtained from SSG on endotoxin-induced experimental DIC in rats. Also, these were tested for their effect on endotoxin-induced blood platelet aggregation, thrombin-induced conversion of fibrinogen and fibrinolysis in vitro experiments with aspirin as a positive agent. The anti-thrombic properties of SSG were also investigated by means of analytical parameters of bood composition. The extracts of SSG and its seven herbs, except Cnidii Rhizoma and Carthami Flos, inhibited the endotoxin-induced DIC and thrombosis in rats. Also the extract inhibited the endotoxin-induced decrease in blood platelets and fibrinogen, and endotoxin-induced increase in fibrin degradation products (FDP) on disseminated intravascular coagulation in normal rats.

In the course of continous work for the discovery of anti-thrombotic constituents from tubers of Gastrodia elata, citric acid 1,5-dimethyl ester was isolated from ethylacetate soluble fraction prepared from the methanol extract. The structure of the compound was determined by the spectroscopic data. The anti-thrombotic effect of this compound was observed with prolonging the bleeding time in thrombin-induced thrombosis model of mice.

The possibility of Chungpesagan-tang, which has been recommended on the stroke patients with constipation in Korean traditional clinic, and its ingredients as a novel antithrombotic agent was evaluated. Most of its ingredients except Puerariae Radix exhibited in vitro antiplatelet aggregation activity. However, Puerariae Radix was significantly effective on ex vivo anti-platelet aggregation activity, whereas Angelicae Tenuissimae Radix, Raphani Semen and Angelicae Dahuricae Radix was not effective. Plasma recalcification was potently inhibited only by Puerariae Radix and Rhei Rhizoma treated with intestinal bacteria. Urokinase was also activated only by Chungpesagan-tang, Angelicae Tenuissimae Radix and Puerariae Radix treated with intestinal bacteria. Chungpesagan-tang exhibited the potent anti-thromboembolic activity activity in vitro. These results suggest that anti-thrombotic activity of Chungpesagan-tang should be activated by intestinal bacteria and may be important in the prevention of thrombosis and cardiovascular diseases, such as myocardial infraction stroke and arteriosclerosis.

복분자는 당도가 낮고 신맛이 강해 과실주로 주로 제조되고 있으며, 복분자주 제조 후 부생되는 주박은 대부분 폐기되고 있다. 본 연구에서는 현재까지 생리활성이 보고된 바 없는 복분자주 주박을 대상으로 열수 추출물, ethanol 추출물 및 이들의 다양한 분획물을 조제하여 항균, 항산화 및 항혈전 활성을 평가하였다. 그 결과, 복분자주 주박의 ethylacetate (EA) 분획은 413~459 mg/g의 높은 polyphenol을 함유하고 있으며, 그람양성세균에 대한 강력한 성장억제 활성과, DPPH 음이온, ABTS 양이온에 대한 우수한 radical 소거능, nitrite 소거능 및 환원력을 나타내었다. 또한 혈액내의 thrombin, prothrombin, coagulation factor 에 대한 저해를 통한 혈액응고저해 활성이 우수하였다. 복분자주 주박의 butanol 분획은 우수한 항산화력과 함께 내인성 혈전 생성에 관련된 aPTT 연장활성을 나타내었으며, aspirin에 필적하는 강력한 혈소판 응집저해 활성을 나타내었다. 한편 복분자주 주박의 열수 추출물의 순차적 유기용매 분획 후의 물 잔류물은 aspirin보다 강력한 혈소판 응집저해를 나타내어 새로운 항혈소판제 개발 소재로 이용 가능함을 확인하였다. 본 연구결과는 폐기되고 있는 복분자주 주박을 이용한 고부가가치 식품 및 향장소재 개발이 가능함을 제시하고 있다.

Purpose: In this study, we evaluated anti-inflammatory activity and anti-thrombosis effect of Manbunbang(MBB) prescribed to chronic PID patients. Methods: We studied inhibitory effect of platelet aggregation, suppression effect of GPIIb/IIIa activity and inhibitory effect of $TXB_2$ and $PGE_2$ biosynthesis which were caused by ADP, epinephrine, collagen and arachidonic acid in vitro. And suppression of pulmonary embolism, changes of related factors in dextran coagulation condition model and anti-oxidative effect of oxidative damage were studied in vivo. Results: MBB extract showed LD50 of $200\;{\mu}g/ml$ or higher in mouse lung fibroblast cells, and significantly decreased the GPT and GPT level in dextran coagulation condition model compared to the control. MBB extract showed dose-dependent inhibition effect on platelet coagulation induced by ADP, epinephrine, collagen, arachidonic acid. MBB extract showed dose-dependent inhibition effect on GPIIb/IIIa activities compared to the control. MBB extract significantly suppressed TXB2 and PGE2 biosynthesis compared to the control. MBB extract suppressed pulmonary embolism triggered by collagen and epinephrine by 37.5% compared to the control. MBB extract significantly suppressed the decrease of speed of bloodstream caused by blood coagulation in dextran coagulation condition model compared to the control. Concluson : The results strongly suggest the anti-inflammatory activity of Manbunbang through anti-thrombus. Various applications using Manbunbang on inflammatory diseases are anticipated. Anti-oxidative efficacy comparison data between the Manbunbang prescription and the drug compositions may be used as important clinical information, and further investigation of anti-oxidative activities of Chrysanthemum indicum and Rhemaniae Radix should be followed.
