In Vivo Model
The A549/DDP tumor cells were subcutaneously injected (2 x 106 cells/mL) into BALB/c-nu mice under aseptic conditions. 6 days later, the average diameter of the tumor reaches 0.5 cm, and the mice were randomly divided into the 1 mg/kg DDP group and the 1 mg/kg DDP + 25mg/kg IO group. Six mice from each group were intraperitoneally administered medications every 2 days for a total of 10 doses each.
