The authors divided 63 Japanese white rabbits (weighing 2.5-3.0 kg) into 5 experimental groups (12 in each group) with oil preparations and 1 control group (3). Under B-guided ultrasound, the VX_2 tumor was punctured into the left lobe of the liver via a 18G needle. After 14 days of implantation, the tumor was used for experiments when the diameter of the tumor was 20 to 30 mm. After the femoral artery puncture, the oil was injected into the 3F catheter (0.5ml / only) and the control group (2.5ml / only). Five oil preparations with different viscosities and densities were prepared before the experiment, Iodized oil and iodine-free opium seed oil, triolein for
