A total of 15 reactions ( 1 per cent Indidence) in I5OO trans- 

 fusions were observed; all were mild. From the standpoint of 

 precipitating causes, they were divided into 3 groups (1) those 

 caused by agglutination (2) allergic reactions and (3) pyrogenlc 

 contamination. The last-named was most frequently encountered. 

 An outline is presented for the prevention of plasma reactions.

The use of concentrated and purified antitoxic B. coll serum 

 in the treatment of Indeterminate ulcerative colitis 



Am. J. Diges. Dls , 9:133-136, 19^2 



Whole and concentrated horse serum^ strongly antitoxic, was 

 prepared from immunizing doses of B, coll . Since this organism 

 is considered to be a secondary invader in chronic ulcerative 

 colitis, intramuscular injections of the concentrated Be coll 

 antitoxin (Shwartzraan) were administered to 29 patients exhibi- 

 ting chronic aspects of colitis. The results were encouraging, 

 22 in 29 patients were benefited by this type of therapy.

The effect of pneumococcus polysaccharide on the circulation of 

 the blood in small blood vessels 



J. Bact. ^3:9^^ 19^2 (Abstract) 



Intravenous injection of various quantities of pneumococcus 

 polysaccharide produced changes in the rate and uniformity of 

 flow of erythrocytes. Increased sedimentation rates were 

 observed.

The action of bacterial toxins on tumors. I. Relationship of 

 the tumor-hemorrhagic agent to the endotoxin antigens of gram- 

 negative bacteria 



Am, J, Hygiene 36:223-242, 19^2 



The antigenic endotoxin of Shigella dysenteriae , on extraction 

 with cold ethylene glycol, yields three components: a phos- 

 pholipid, non-toxic, non-antigenic and not a hapten; a poly- 

 saccharide, comprising approximately 50 per cent of the endotoxin.
