Two days after exsanguination, the lungs were killed, and the resulting lungs were sectioned into 1 mm-sized sections. Tyrode's solution was added to the lung sections to prepare suspensions, and treated with a test drug solution diluted to a predetermined concentration in 0.15M phosphate buffer for 5 minutes. The mixture was incubated for 15 minutes, and the amounts of histamine and SRS-A in the released supernatant were measured. Histamine is measured by the method of May, CD et al. [Journaln of Allerg
y 46 , 12-20 (1970)], and the measurement of SRS-A was carried out by the method of Watanabe et al. [Microbiology and Immunologi (Microbiology and Immunologi).
