260. PYRIgER 



Ge^^es Codex, (Dresden), 1937* Po 1350 



A temperature-increasing bacterial product from apathogenlc 

 colon bacteria grown in milk„ It is marketed in seven strengths, 

 ranging from 50 million to 500 million bacterial cells per cc. 

 Three types of packaging are obtainable. It has been used 

 extensively in paresis and other luetic conditions involving 

 . the central nervous system^ but uses in other types of in- 

 fection have been reported. The beginning dose is 0.5 to 1.0 

 cc. of strength I, with gradual increases to maintain desired 

 reactions.

Chemical investigations on the active principles of the phen- 

 omenon of local skin reactivity to bacterial filtrates I. 

 Purification by dialysis and attempts at fractional precipi- 

 tation 



Jo Expero Med. 65^323-337, 1937 



The active principles in the phenomenon of local skin reactivity 

 (Shwart.em.an reaction) are retained by cellophane membranes. 

 This method effects considerable purification, for culture 

 filtrates of E. typhosa, B. coli and meningococcus , increasing 

 reactive potency about three-fold. Fractional precipitation 

 of concentrates of these filtrates, using acid, dilute alkali 

 or alcohol, was not successful in this study.
