Serum and whole blood of rats resistant to sensitive to Jensen tumor effect on the acceptance (taking) and growth of Jensen tumor grafts.
The results obtained by concomitent inoculation of four kinds of homologous sera or blood into Wistar and Long Evans rat grafted with Jensen tumors are analysed as regards taking and growth of the grafts. The four kinds are: 1. serum from rats naturally resistant to Jensen graft (R1); 2. serum from rats that became resistant to Jensen graft after the initial tumor graft was excised (R2);3. serum from normal sensitive rats (S); 4. serum from tumorbearing rats in an advanced stage of development (B). Experiments were repeated four times. All sera proved to stimulate tumor takes and growth, but that effect was more obvious will the serum or blood from rats naturally resistant to Jensen tumor (R1). the results are discussed.
