Some alterations in the amount of blood aminoacids in the Wistar rats inoculated with the 256 Walker carcinoma

Abstract

Investigations of the aminoacids in Wistar rats serum is done ; four being found in large proportions : Leucine, Valine, Alanine and Lysine.

These four aminoaccids are quantitatively increased in rats subcutaneously inoculated with the 256 Waler carcinoca. This increase is appreciable above all between the 5 and 10 days of inoculation, not being so intense bet­ ween the 10 and 15 days.

An increase of Valine and Alanine is ob­ served in rats with ascitic Walker tumor of 4 days of evolution, but not of the other two aminoacids.
