The rate of bacteriophage inactivation by filtrates of 

 Escherichia coll cultures 



J= Gen, Physiol. 24:^37-445, 19^1 



The antl- coll phage Is inactivated by culture filtrates of 

 B, coll in a pattern influenced by the temperature at which 

 the reaction occ-urs. The rate of inactivation at 37*^ Co 

 is proportional to phage concentration and filtrate con- 

 centration; at 0° C, the rate is proportional to the square 

 root of the concentration of the filtrate c Coll -phage is in- 

 activated by other colloids (starchy inulin, gum arable); the 

 inactivation is delayed by either very high or very low salt 

 concentrations ,

The influence of fever on the vago -insulin and sympathetico- 

 adrenal systems 



Endocrinol, 29il41-l43, 1941 



Typhoid -paratyphoid vaccine was injected Intraperitoneally 

 (0,7 cc , per kg,) into the normal rat and into adreno-demedul- 

 lated or vagotomlzed animals. One group received vaccine after 

 extirpation in toto of adrenals^ and medulla, and sectioning 

 of the vagus nerves. The vaccine produced hyperglycemia in the 

 normal animal, hypoglycemia in the adreno-demedullated animals 

 but no alterations in blood sugar after vagus section in adreno- 

 demedullated rats, Hjrperthermia appeared in the normal and 

 vagotomlzed rat; removal of adrenals and medulla produced 

 hypothermic reactions. In the vagotomlzed animal^ both hyper- 

 thermia and high blood sugar levels persisted much longer than 

 in the normal animal. The excitation of autonomic centers 

 may affect discharge over the vago-insulin system as well as 

 in the sympathetico-adrenal network,

The hydrolytic degradation of the antigenic complex of Bact . 

 typhosum Ty 2 



Biochera, J, 35:564-577, 1941 



Dissociation by slow hydrolysis of the antigen of B. typhosa 

 Ty 2 yielded the following components: a polysaccharide, consti- 

 tuting 50 to 60 per cent of the total; an insoluble polypeptide
