Ten of thirteen patients with positive histolatex agglutination titers of 1:32 or greater had no evidence of acute histoplasmosis. Three of these false positives had rheumatoid arthritis. A fourth had a rising mycoplasma complement fixation titer, and the fifth had a high titer of cold agglutinins. All of these are associated with abnormal immunoglobulin M production. To evaluate the role of rh...

The term "cancer" is an umbrella for a large number of malignant diseases which vary in severity and type. Therefore, many problems are associated with crossmatching a patient with this diagnosis. Blood use may vary greatly in amount and in the urgency of its need. The diseases themselves may cause cold reactive auto agglutinins to appear. The diseases and their treatments may cause red cell an...

The observation that ABO agglutinins are present in a wide variety of pollens (Denborough, 1964) and so must commonly be inhaled, and the knowledge that plant agglutinins are antigenic (Mikela, 1957), prompted us to study secretor status in allergic disease of the respiratory tract, namely in asthma and hay fever. The opportunity has been taken to measure the amount of isoagglutinins present in...

Although the unit&an theory of antibodies has gained general acceptance since its formulation by Zinsser and others (l), quantitative evidence for the identity of agglutinins and precipitins has been lacking. Zinsser (2) has attempted to reconcile mathematically the apparent discrepancy between the serum dilutions in which agglutination and precipitation occur and Jones (3) has shown that collo...
