ObjectiveTo study the feasibility of the establishment of transplantated hepatic cancer models in SD rats. MethodsThe male weaning SD rats were inoculated and transgenerated from the celiar transplantation tumor rats (W2562k) by intraperitoneal injection of abdominal fluid of tumor cells, another weaningSD rats were prepared for the models of solid tumor by subcutaneous inoculation of the abdominal fluid of tumor cells. The solid tumors were cut to pieces of 0.2 cm×0.2 cm×0.3 cm,which were implanted into the liver of the adult male SD rats, and the transplantation hepative tumor models were established. After 7 days, the volume and weight of tumor mass was measured. ResultsThe successful rate of model was 100% (82/82), the natural extinctive rate was 0 (0/82), the successful rate of inoculation was 100% (15/15). ConclusionSD rats are economical, the successful rate of model was high, the natural extinctive low, so the SD rats are ideal selection in establishing transplantation liver cancer model.
