Objective: The antiplatelet agent aspirin has been widely used for treating atherosclerosis in western medicine, and its efficacy has been proven in cardiac and extracardiac vascular diseases. On the other hand, Hyeolbuchukeo-tang has been widely used for treating blood stasis syndrome in traditional medicine. Therefore we investigated whether Hyeolbuchukeo-tang could have a synergic effect along with aspirin. Methods & Materials: Male $ApoE^{(-/-)}$ mice were randomly divided into three different experimental groups: a non-treated group(Control group), an aspirin-treated group(AP group), and an aspirin with Hyeolbuchukeo-tang-treated group(APH group). The control group was fed only an atherogenic diet, the AP group an atherogenic diet plus Aspirin 5 mg/kg, and the APH group an atherogenic diet plus Aspirin 5 mg/kg with Hyeolbuchukeo-tang 100 mg/kg. We investigated plasma lipid with liver function test, and performed the histological investigation of liver and abdominal aorta. Results: 1. We investigated photomicrographic changes of liver and abdominal aorta tissue. They showed that histological injury of aorta and lipid accumulations of the liver were lower in the AP and APH groups than in the control group. 2. In the APH group, plasma triglyceride levels were significantly lower than those in the control and AP groups. 3. There were no differences in aspartate aminotransferase and alanine aminotransferase levels among the control, AP and APH groups. Conclusion: The above results show that a combined treatment of Hyeolbuchukeo-tang and aspirin has a somewhat synergic effect in terms of inhibiting vessel injury and decreasing lipid deposits on liver cells without liver toxicity.

Objective : This study was conducted to clarify the association factors and clinical significance of the CT angiography (CTA) spot sign and hematoma growth in Korean patients with acute intracerebral hemorrhage (ICH). Methods : We retrospectively collected the data of 287 consecutive patients presenting with acute ICH who arrived within 12 hours of ictus. Baseline clinical and radiological characteristics as well as the mortality rate within one month were assessed. A binary logistic regression was conducted to obtain association factors for the CTA spot sign and hematoma growth. Results : We identified a CTA spot sign in 40 patients (13.9%) and hematoma growth in 78 patients (27.2%). An elapsed time to CT scan of less than 3 hours (OR, 5.14; 95% CI, 1.76-15.02; p=0.003) was associated with the spot sign. A CTA spot sign (OR, 5.70; 95% CI, 2.70-12.01; p<0.001), elevated alanine transaminase (GPT) level >40 IU (OR, 2.01; 95% CI, 1.01-4.01; p=0.047), and an international normalized ratio ${\geq}1.8$ or warfarin medication (OR, 5.64; 95% CI, 1.29-24.57; p=0.021) were independent predictors for hematoma growth. Antiplatelet agent medication (OR, 4.92; 95% CI, 1.31-18.50; p= 0.019) was significantly associated with hematoma growth within 6 hours of ictus. Conclusion : As previous other populations, CTA spot sign was a strong predictor for hematoma growth especially in hyper-acute stage of ICH in Korea. Antithrombotics medication might also be associated with hyper-acute hematoma growth. In our population, elevated GPT was newly identified as a predictor for hematoma growth and its effect for hematoma growth is necessary to be confirmed through a further research.

Background and Objective: Atherosclerosis is a diffuse, systemic disease that affects the coronary, cerebral, and peripheral arterial trees. Clopidogrel is widely used antiplatelet agent and its efficacy has been proven in cardiac and extracardiac vascular diseases, but it has several side effects. Therefore we investigated whether Sopunghwalhyeoltang, which is widely used for treating the blood stasis syndrome in traditional medicine, could decrease the side effect of antiplatelets and have a synergic effect. Methods & Materials: Male $ApoE^{(-/-)}$ mice were randomly divided into three different experimental groups, non-treated group (Control group), clopidogrel-treated group (CP group) and clopidogrel with Sopunghwalhyeol-tang treated group (CPS group). The control group was fed with only an atherogenic diet, the CP group an atherogenic diet plus clopidogrel 25mg/kg and the CPS group an atherogenic diet plus clopidogrel 25mg/kg with Sopunghwalhyeol-tang 100 mg/kg. We investigated plasma lipids with liver function test, and performed a histological investigation of liver and abdominal aorta. Results: 1. Photomicrographs of liver and abdominal aorta tissue showed lower histological injury and lipid accumulation in the CP and CPS groups than those in the Control group. 2. In the CPS group, plasma triglyceride level was significantly lower than in the Control and CP groups. 3. In the CPS group, the plasma aspartate aminotransferase (AST) level was significantly lower than in the CP group. Conclusions: The above results shows that a combined treatment of Sopunghwalhyeol-tang and clopidogrel have a synergic effect through inhibiting vessel injury and decrease the side effects of clopidogrel alone.

Objective : Chronic subdural hematoma (CSDH) patients using antithrombotic agents (AT) at high risk for cardiovascular disease are increasing. The authors aimed to analyze the factors influencing outcome by targeting patients using AT and to establish a desirable treatment strategy. Methods : A retrospective analysis was performed on data from 462 patients who underwent burr hole trephination (BHT) surgery for CSDH at five hospitals from March 2010 to June 2021. Outcomes included incidence of postoperative acute bleeding, recurrence rate, and morbidity or mortality rate. Patients were divided into the following four groups based on their history of AT use : no AT. Only antiplatelet agents (AP), only anticoagulants (AC), both of AP and AC. In addition, a concurrent literature review was conducted alongside our cohort study. Results : Of 462 patients, 119 (119/462, 25.76%) were using AT. AP prescription did not significantly delay surgery (p=0.318), but AC prescription led to a significant increase in the time interval from admission to operation (p=0.048). After BHT, AP or AC intake significantly increased the period required for an in-dwelling drain (p=0.026 and p=0.037). The use of AC was significantly related to acute bleeding (p=0.044), while the use of AP was not (p=0.808). Use of AP or AC had no significant effect on CSDH recurrence (p=0.517 and p=1.000) or reoperation (p=0.924 and p=1.000). Morbidity was not statistically correlated with use of either AP or AC (p=0.795 and p=0.557, respectively), and there was no significant correlation with mortality for use of these medications (p=0.470 and p=1.000). Conclusion : Elderly CSDH patients may benefit from maintenance of AT therapy during BHT due to reduced thromboembolic risk. However, the use of AC necessitates individualized due to potential postoperative bleeding. Careful post-operative monitoring could mitigate prognosis and recurrence impacts.

배경: 아스피린과 플라빅스는 관상동맥 환자들에게 가장 흔히 사용하는 항혈소판 제제이나 수술 후 출혈 성향의 증가에 대한 우려 때문에 수술 5일에서 7일 전에 복용을 중단하는 것이 일반적이다. 본 연구에서는 이들 약제들의 지속적 사용이 무심폐기 하 관상동맥우회 술(Off pump coronary artery bypass grafting, Off pump CABG) 후의 결과에 어떤 영향을 미치는지에 관하여 조사하였다. 대상 및 방법: 2004년 3월부터 2005년 2월까지 Off pump CABG를 시행 받은 123명의 환자들을 대상으로 하여 수술 전후에 아스피린과 플라빅스를 끊지 않고 지속적으로 사용한 군(n=45, 36.6$\%$)과 적어도 수술 1일 이전에 끊은 군(n=78, 63.4$\%$) 사이에 수술 전후 혈소판, 헤모글로빈/헤마토크리트 수치, 수술 후 출혈량, 도관 개통률, 수술 시간 등을 비교하였다. 또한 대상환자들을 수술 전에 아스피린을 1달 이상 사용했던 장기 사용군과 그렇지 않은 군으로 구분하여 상기 요소들을 비교하였다. 결과: 수술에 의한 사망은 없었으며 출혈에 관한 합병증으로는 출혈에 의한 재수술과 상부 소화관 출혈이 각각 1예씩 있었다. 지속적으로 사용한 군과 그렇지 않은 군의 비교에 있어서는 수술 직후와 수술 후 1, 2일의 혈소판 수치가 지속적 사용군에서 유의하게 낮았으나(p=0.02, p=0.002, p=0.021) 수술 후 출혈량, 수혈 빈도, 출혈 관련 합병증 및 도관의 개통률에는 차이가 없었다 아스피린을 1달 이상 사용한 장기 사용군의 경우 그렇지 않은 군에 비하여 수술 전후의 혈소판 수치가 지속적으로 낮았으나 출혈량, 수혈 빈도, 합병증 및 도관의 개통률에는 차이가 없었다. 결론: 아스피린과 플라빅스의 Off pump CABG 전후의 지속적 사용은 수술 후 일시적인 혈소판 수치의 감소를 초래할 수 있으나 수술 후 출혈량, 수혈 여부, 수술 시간, 출혈과 관련된 합병증 및 도관의 개통률에는 영향을 주지 않았다. 그러므로 Off pump CABG에 있어서 아스피린과 플라빅스는 수술 전까지 지속적으로 사용하여도 될 것으로 생각한다.

전통주 주박을 이용한 고부가가치 식품소재 개발을 위해, 상업적 시설에서 생산된 3종 약주(J-B, J-S, J-Y) 및 2종 탁주(J-H, J-W) 주박의 ethanol 추출물 및 열수 추출물을 조제하고 이들의 혈액응고 저해활성, 혈소판 응집저해 활성 및 인간 적혈구 용혈활성을 평가하였다. 5종 주박의 pH는 3.90~4.29로 유사하였으나, brix는 5.0~27.0으로 다양하게 나타났으며, 수분 및 알코올 함량에서도 시료에 따라 1.8배의 차이를 나타내었다. 주박의 색차와 성분은 첨가된 부재료 및 사용누룩에 좌우되었으며, J-W 주박의 경우 수분함량이 80.3%, brix 13, 알코올 함량 1.8%를 함유하여 다른 주박에 비해 다양한 식품제조에 용이하게 이용 가능하리라 판단되었다. Ethanol 추출효율은 J-H, J-W, J-B, J-S, J-Y의 순, 열수 추출효율은 J-S, J-B, J-W, J-H, J-Y의 순으로 높았으며, 총폴리페놀 및 총플라보노이드 함량은 ethanol 추출물 중에서는 J-H, 열수 추출물 중에서는 J-Y 주박에서 가장 높았다. 5종 주박의 10종 추출물은 모두 5 mg/ml 농도까지 인간 적혈구에 대한 용혈활성이 나타나지 않았으며, J-B, J-S, J-Y의 약주 주박의 ethanol 추출물에서 유의적인 혈액응고저해 활성이 나타났으며, J-W 탁주 주박의 열수 추출물에서 thrombin 저해 활성과 J-B, J-S 및 J-H 주박 열수 추출물에서 혈액 응고인자 저해활성을 확인하였다. 혈소판 응집저해 활성평가의 경우 J-W 탁주 주박의 ethanol 및 열수 추출물에서만 아스피린에 필적하는 우수한 활성이 확인되었다. 본 연구결과는 다양한 약주 및 탁주 주박이 항혈전 활성을 가지고 있으며, 주박으로부터 항혈전제 개발이 가능함을 제시하고 있다.
