FIBRINOLYTIC ACTIVITY OF THE FLUID OF WHEALS INDUCED BY INHALANT ALLERGENS AS COMPARED TO THOSE INDUCED BY INJECTION OF HISTAMINE

[摘要] Fluid from wheals induced by the intra-dermal injection of histamine, Compound 48-80, and allergens was tested for fibrinolytic activity by a modified fibrin plate method. No marked fibrinolytic activity was observed, although the addition of streptolysin to the fluid revealed a plasminogen content comparable to that of serum. The data tend to minimize but not rule out the possible role of plasmin in the intracutaneous response to inhalant allergens.
