Abstract
The progressive development of diabetes mellitus (DM2) in db/db mice is associated with three stages of impaired carbohydrate metabolism and redox processes. In db/db mice, the content of erythrocytes, hemoglobin, and leukocytes was found to decrease already in stage I of DM2. In the II and, in particular, III stages, an increase in platelets, percentage of neutrophils, monocytes, and eosinophils was observed, along with a decrease in lymphocytes. In the bone marrow of db/db mice, a decrease in the proportion of living cells and an increase in the number of damaged cells were determined already in stage I, but especially in stage III, mainly due to aponecrotic cells. Therefore, along with the progression of DM2 and a marked decrease in the effectiveness of redox processes, particularly in stage III, hematopoiesis processes are inhibited and disturbances in the ratio of neutrophil/lymphocyte cell populations increase. This indicates the development of severe hypoxia, activation of a systemic inflammatory reaction, and inhibition of reparative processes that create conditions for the development of dangerous complications.
Supporting agencies: the work was partially completed within the framework of the state assignment on the topic: “Assessment of the body's adaptive responses to the action of physicochemical and environmental factors” (No. FGFU-2022-0010).
