The nude mice were raised in our laboratory for a week before the experiment. Then, 5 x 10⁶ MKN-1 cells were subcutaneously injected to establish the subcutaneous xenograft tumour model in nude mice. When the maximum diameter of the xenograft tumours grew steadily to 1 cm, they were dissected completely and cut into 1 mm³ tissue fragments. Then, the tissue fragment was inserted into the surface of the serosa on the greater curvature of the stomach. Different doses of PB (2.5 mg/kg or 5.0 mg/kg) were given by intraperitoneal injection once a day for 3 weeks. The control group was given the same volume of vehicle. The positive control group was given 5-Fu at the dose of 10 mg/kg. The body weight and tumour size of nude mice were recorded. Mice were administered fluorescein substrate (150 mg/kg) intraperitoneally for in vivo imaging twice a week on a Xenogen IVIS 200 imaging system (Caliper Life Sciences, USA). The tumour inhibition rate was analysed using LT Living Image 4.3 Software.
