This study was performed to compare the effect of Ojeoksan which have extracted by varied extractor(press extractor : PE, pressless extractor : PLE, short acting extractor : SE) on model of blood stasis in rats, Except for the normal group, hydrocortisone acetate(HA;25mg/kg in ethanol. IM) to induce experimental blood stasis model for 1 weeks and each extract of Ojeaksan was administrated after 1hr following HA injection for 1week. We measured the hematocrit, the platelet count, the prothrombin time, levels of fibrinogen in rats' blood, The sample Ⅰ(Ojeoksan extracted by PE) group showed significant decrease of hematocrit. prothrombin time and significant increase of the platelet count, levels of fibrinogen in comparison with those of the control group, The sample Ⅱ(Ojeaksan) extracted by PLE) group showed significant decrease of hematocrit and significant increase of levels of fibrinogen in comparison with those of the control group. Administration of the sample Ⅲ(Ojeaksan extracted by SE) group showed significant decrease of hematocrit and significant increase of the platelet count, levels of fibrinogen in comparison with those of the control group.
