TEBE SAFIN 73 



Preliminary treatment of goats and guinea-pigs with Tebesapin seems to offer a 

 certain protection against future infection. Evidence of its beneficial action in man is 

 still insufficient. Its harmlessness, however, has been demonstrated, so that one is 

 justified in its use. 



Pursuing the same plan, Deycke and Much have attempted to obtain products for 

 immunization by shaking tubercle bacilli with lecithin, neurin, cholin and lactic acid. 

 Their findings have been disputed, although the author has reached conclusions similar 

 to those of Deycke and Much. Further corroborative evidence is necessary.
