[A chronobiological analysis of the lymphocyte dehydrogenase activity in the peripheral blood of rats with Walker 256 carcinosarcoma].

Abstract

In a series of experiments the alpha-glycerophosphate dehydrogenase and succinate dehydrogenase (SDH) activities were daily determined simultaneously by the cytochemical method in peripheral blood lymphocytes of normal rats and those with the Walker carcinosarcoma. Using an original algorithm a hierarchy of biorhythms was singled out by a computer according to individual changes in the dehydrogenase activity for each rat. The mean level of succinate dehydrogenase activity was higher than that of alpha-glycerophosphate dehydrogenase. A set of discovered biorhythms and their representation were identical in the both enzymes. The tumor transplantation caused changes in the phase coordination of investigated dehydrogenases in all rhythms and promoted an increase of the succinate dehydrogenase amplitude as compared with the alpha-glycerophosphate dehydrogenase amplitude in certain rhythms. It is concluded that biorhythmological parameters of these enzymes may be used for characterization of the tumor-bearing host.
