발암물질을 무독화시키는 QR 생성 유도를 살펴보기 위하여 석창포 약침액 및 열수추출액을 생쥐의 간암세포인 Hepa1c1c7에 처리하여 측정한 결과, 석창포 약침액의 농도를 증가시킬수록 높은 QR 생성율을 보였으며, QR 활성 유도효과 보다는 낮았찌만 GSH와 GST 생성도 증가하였다.
Induction of phase II enzymes such as quinone reductase (QR) and glutathione S-transferase (GST) is considered a major mechanism of protection against initiation of carcinogenesis. The present study was performed to evaluate the chemopreventive activity of Acori Graminei Rhizoma aqua-acupuncture solution (AGRAS) and Acori Graminei Rhizoma water-extracted solution (AGRWS) by measuring the induction of phase II enzymes. AGRAS and AGRWS are potent inducers of quinone reductase activity in murine hepatoma Hepa1c1c7 cells. The levels of GSH and GST was increased sightly with AGRAS and AGRWS. These results suggest that AGRAS and AGRWS may act as blocking agents against carcinogenesis by induction of phase II enzymes.
