초록

한방생약제의 항혈전 및 혈소판 응집 억제 효능을 탐색하기 위하여 하고초의 물 추출물로 혈전 용해능 활성과 혈액 응고시간 지연효과 즉 PT (prothrombin time), APTT (activated partial thromboplastin time)와 혈소판 응집억제 활성 등에 대해 항혈전 효능을 평가하였다. 혈전용해도를 측정하는 fibrin plate가 용해되어 형성된 투명환의 넓이를 측정하는 실험을 진행한 결과 혈전용해도가 농도의존적으로 효능을 나타내었다. 혈액 응고 cascade에 미치는 영향을 알아보기 위해 혈액 응고 시간 지연 및 단축 효과를 확인하고자 APTT와 PT에 미치는 영향을 조사한 결과 PT의 경우 10 mg/ml, 5 mg/ml의 경우에는 대조군보다 우수한 지연효과를 보였다. APTT의 경우에는 10 mg/ml, 5 mg/ml는 대조군과 비교하여 매우 탁월한 지연효과를 보이고, 2.5 mg/ml, 1.25 mg/ml에서도 높은 지연효과를 나타냈다. 혈소판의 응집에 따라 형성되는 두 전극 사이에 형성된 전기적 저항의 변화로 나타나는 실험을 시행한 결과 하고초의 ADP와 collagen에서 뛰어난 응집억제 활성을 보였다. 따라서 위의 항혈전 효능평가 실험결과를 볼 때 하고초를 향후에 혈전 질환의 치료제 개발에 효과적으로 이용될 수 있을 것으로 사료된다.

This study was performed to develop effective antithrombotic agents from traditional herb extracts. Prunella vulgaris L. has been used traditionally as a medical resource in cancer therapy, as well as treatment of hypertension and inflammation, and as a diuretic. However, the effects of Prunella vulgaris on thrombosis and platelet activation have not been clearly understood. Antithrombotic and antiplatelet activities of oriental medicinal herbs were investigated by evaluating the effect of the aqueous extract from Prunella vulgaris on the blood coagulation, platelet aggregation and fibrinolysis. Prunella vulgaris extracts showed effective anticoagulant activity in coagulation times such as activated partial thromboplastin time (APTT) and prothrombin time (PT). Prunella vulgaris also inhibited adenosine diphosphate (ADP)- and collagen-induced platelet aggregation. In addition, evaluation of fibrinolytic activity showed that the Prunella vulgaris extracts have high solubility. From these results, it is suggested that Prunella vulgaris can be a potential candidate for anticoagulants and antiplatelets, as well as fibrinolytic agents.
