[Comparative study of the changes in lactate dehydrogenase isoenzymatic spectra in the course of organogenesis in mice].
The dynamics of changes in the lactate dehydrogenase (LDH) spectra during organogenesis in CBA mice has been studied by means of ultramicroelectrophoresis. The embryonic period of development is characterized by the predominance of cathodic isozymes (LDH-5 and LDH-4) in all the organs under study. The increase of anodic isozymes (LDH-1 and LDH-2) takes place in the heart, kidneys and brain as the development proceeds. The first reliable differences in the LDH spectra of different organs appear on the 11th day of embryogenesis. On the basis of comparison with the help of criterion gamma, the LDH spectra of the organs under study can be divided into two groups: I--heart, lungs, kidneys and brain (tendency towards the increase of H-subunits) and II--intestine, liver and muscles (tendency towards the increase of of M-subunits). The LDH spectra of adult animals are divided into 4 distinct groups: I--heart and kidneys, II--brain, III--lungs and muscles, IV--liver.
