DISCUSSION 
G. E. BiSGARD, University of Wisconsin, 
Madison : Has anyone measured pulmonary ar- 
tery pressure in these cats? Also, has anyone 
tried to simply inject antigen into the lung, 
tryin-g to develop the lesion that M^ay? 
Dr. Swerczek: I have injected several anti- 
gens without success in cats. I personally 
haven't measured the pulmonary arterial pres- 
sure in these cats, but Dr. Jonas at Yale has 
done considerable work with this.
