intratumoral injection of thymidine ( dthd ) into mice bearing an ehrlich ascites solid tumor in combination with an ip injection of 5-fluorouracil ( fura ) was performed to investigate the following : ( a ) whether intratumoral injection of dthd would increase both the incorporation of fura into tumor rna and the antitumor activity of fura as effectively as ip injection of dthd , and ( b ) whether intratumoral injection of dthd would have a selective advantage for increasing the incorporation of fura into the tumor rna , relative to normal tissue rna .
