Plasma bradykininogen levels are related to the bodys ability to resist inflammation. In a 1968 study (Eilam, N., Johnson, P. K., Johnson, N. L., and Creger,W., Bradykininogen levels in Hodgkins disease, Cancer, 22, pp. 631634), levels were measured in normal patients, in patients with active Hodgkins disease, and in patients with inactive Hodgkins disease. The following data (in micrograms of bradykininogen per milliliter of plasma) resulted. Normal Active Hodgkins Disease Inactive Hodgkins Disease 5.37 3.96 5.37 5.80 3.04 10.60 4.70 5.28 5.02 5.70 3.40 14.30 3.40 4.10 9.90 8.60 3.61 4.27 7.48 6.16 5.75 5.77 3.22 5.03 7.15 7.48 5.74 6.49 3.87 7.85 4.09 4.27 6.82 5.94 4.05 7.90 6.38 2.40 8.36 Test, at the 5 percent level of significance, the hypothesis that the mean bradykininogen levels are the same for all three groups.
