title: Lactic dehydrogenase isozyme distributions in lymphocytes from normal and leukemic mice.
abstract: LDH isozyme distributions were studied in the thymocytes of normal and spontaneously leukemic mice. In the normal animals, H:M ratios were found to be higher for more mature cells of adult animals than for less mature thymocytes of the neonates. However, thymocytes from leukemic animals bearing mature phenotype displayed very low values of H:M ratios. From these results, the relationship between the changes in LDH-isozyme distributions in AKR thymocytes and their progressive maturation appears to be equivocal. Alterations in isozyme distribution patterns, reflecting a decrease in H:M ratios, on the other hand, appears to be a characteristic feature of terminal stages of this murine leukemia.
