수종 생약제제들의 혈소판 응집억제 작용

Platelet anti-aggregating activities were evaluated with three combined crude drug preparations which have been used for 'eahyul'-one of the pathological concept in oriental medicine presumably concerning blood stasis or stagnant syndrome. The water extract of each combined preparation and each component plant was tested for their effects against ADP, arachidonic acid (AA) or collagen induced rat platelet aggregations. Mild inhibitory activities were observed with all the three tested preparations, Kaechibokryung-Hwan, Dangkqijakyak-San and Ohnkyung-Tang, and the component plants which are included in at least two of the above preparations.
