ADVENTURES IN RADIOISOTOPE RESEARCH 



Figure 7 shows the transport of iron from the labelled transferrin iron 

 of the plasma of a normal rabbit into the intercellular and cellular space. 

 The iron disappearing from the plasma which is not found in the inter- 

 cellular space has already been transferred into the cells.

 Normal Kaninchen = normal rabbit. 

 Intracellulares Fe = intracellular iron. 

 Plasma Fe = plasma iron. 

 Lymphe Fe = lymph iron. 



Figure 8 shows the powerfully accelerated transport of globulin iron 

 from the plasma of an infected rabbit; this acceleration is partly attri- 

 butable to the fact that the turnover of red corpuscles (shorter life-time) 

 is accelerated in the infected animal.
