Objective To observe the effect of curcumin on the cholesterol metabolism in vascular smooth muscle cell - derived cholesterol - road cell, and investigate the effct of SREBP - 1 at the process. Methods using vascular smooth muscle cell - derived cholesterol - road cell as investigating object, curcumin of different density (0,12.5,25.0,50.0 μmol/L for 24 hours)and different time(0,6, 12,24,48 h of 25.0 μmol/L) effects on cells, and using high performance liquid phase analytic process detects the level of total, free and esterified choles...
