102 NEUTRON EFFECTS ON ANIMALS 



in the total protein content for both extract A and extract C, and a broaden- 

 ing and overlapping of the fibrinogen and 7 globulin boundaries for 

 extract C. 



SUMMARY 



Preliminary electrophoresis studies have been made on the plasma, 

 serum, and sonicized bone marrow extracts of five rabbits, two of which 

 were irradiated with a single dose of 135 n. 



An anomalous relationship was found between the protein concentrations 

 of the plasmas and the corresponding sera. 



When examined by electrophoresis, samples of plasma subjected to sonic 

 treatment similar to that given the corresponding bone marrow showed no 

 significant differences from the untreated samples. 



Shght differences were observed between the data for irradiated and non- 

 irradiated rabbits, but in view of the paucity of experimental animals, these 

 differences must be corroborated by further evidence before definite con- 

 clusions can be drawn.
