These findings indicate that the changes in the levels of free amino acids are related 
to the overall reduction of the leukocyte count and indicate marked effects upon 
metabolism, particularly of leukocytes. 
The compounds most affected are glutamic and aspartic acids and taurine. There 
are changes in the levels of other free amino acids in some cases. At times virtually 
all of the free amino acid levels of plasma and leukocytes are altered. The appearance 
of new compounds has been noted at higher dosage levels. The appearance of these 
compounds coincides with the marked fall of the leukocyte mass after drug administra- 
tion and for this reason the isolation of the unknowns in adequate amounts for com-
