[Structural anomalies of dog hemoglobin after ionizing irradiation]

Heterogeneity of dog hemoglobin is established with application of chromatographic analysis. Ionizing radiation (4 Grey) induces no changes in the ratio of hemoglobin components. The comparative dactylographical analysis of the hemoglobin components in norm and in different periods after irradiation revealed differences in responses to tryptophan in peptide T-25. The changes found are connected with disturbances in the structure of the DNA molecule as well as with modification of the protein molecule under conditions of radiation injury.
