초록

배경 : Platelet Function Analyzer-100 (PFA-100, Dade-Behring, Germany)은 높은 shear flow 상태에서 혈전이 형성되는 인체내 과정을 가상하여 구형의 입구가 폐색되는데 걸리는 시간을 측정한다. 저자들은 한국인 성인을 대상으로 PFA-100의분석전 변수를 확인하고, 폐색시간(closure time, CT)의 참고범위를 설정하고자 하였다. 방법 : 총 120명의 건강한 성인을 대상으로 하였다. Collagen/epinephrine 카트리지(CEPI)와 collagen/ADP 카트리지(CADP)의 폐색시간을 측정하였다.결과 : 중앙 95백분위수를 참고범위로 하였을 때, CEPI-CT는82-182초였고, CADP-CT는 62-109초였다. 여성이 남성보다CEPI-CT, CADP-CT 모두 유의하게 연장되었다(각P=0.034,0.022). 40세 이상의 연령군에서 그이하보다 유의하게 짧은 CT를 보였다(각 P=0.002, 0.003). 오후에 측정한 CEPI-CT와CADP-CT는 오전에 측정한 결과보다 모두 유의하게 연장되었다(모두 P<0.0001). O형 혈액형군에서 비-O형 군보다 CEPI-CT와 CADP-CT가 모두 유의하게 연장되었다(각각 P=0.0003,<0.0001). CADP-CT는적혈구용적률과 약한 상관관계(r=-0.296,P=0.003)를 보여주었으나 CEPI-CT는 그렇지 않았다.
