Abstract
Schwartzmann's reaction and Arthus' phenomenon were produced in rabbits and studies were made on their relation to the clinical allergy.
Results showed the increase of albumin and α-globvlin and the decrease of β and γ-globulin in the case of Schwartzmann's reaction being mostly the same as the respective findings of urticaria and strophulus, while, in the case of Arthus' phenomenon, the decrease of albumin and the increase of globulin being mostly the same as the findings of nephritis and asthma. The pictures of serum protein fractions, moreover, are considered to be closely related with the period required from the time of occurrence to the appearance of the reaction.
