발암물질을 무독화시키는 QR 생성 유도를 살펴보기 위하여 황기 약침액 및 열수추출액을 생쥐의 간암세포인 Hepa1c1c7에 처리하여 측정한 결과, 황기 약침액의 농도를 증가시킬수록 많은 QR 생성율을 보였으며, GSH 생성이 증가하였고, GST 생성 또한 증가하였다.
Induction of phase II enzymes such as quinone reductase (QR) or glutathione S-transferase (GST) is considered a major mechanism of protection against initiation of carcingenesis. This study was desinged to investigate the potential of Astragali Radix Aqua-acupuncture Solution (ARAS) to induce phase II enzymes and glutathione (GSH) in murine hepatoma cells grown in microtiter plate wells. ARAS was potent inducers of QR activity. ARAS was induced about 2.6-fold at concentration of $5{ imes}$. In addition, GST activity was increased with ARAS. GSH levels were increased about 1.2-fold with ARAS at concentration of $0.1{ imes}$. These results suggested that ARAS may act as blocking agents against carcinogenesis by induction of phase II marker enzymes.
