Abstrakt: The dynamics of nephropathy development in rats with type 2 diabetes mellitus, caused by a high-fat diet and the streptozotocin administration (25 mg/kg), and metabolic syndrome, caused by addition of 20% fructose solution to the diet, was evaluated during the experiment. Models with moderate severity of metabolic changes without significant changes in body weight were obtained after 24 weeks. To study neuropathy severity, the method of electroneuromyography was used; the velocities of motor and sensory excitation propagation along the caudal nerve fibers were measured. In modeled diabetes mellitus against the background of hyperglycemia, a marked decrease in motor and sensory propagation rates was observed, and an increase in the response durations was noted from week 12 to week 24, indicating pronounced neuropathy. In the fructose model, the motor response duration increased from week 12, which possibly indicates the development of peripheral neuropathy.
