Specificity of Metabolic Syndrome Model Reproduction at Pubertal and Adult Male Rats

Open access


Background and Aims: Comparative estimation of metabolic syndrome (MS) mediated changes of blood, cardio-vascular system, liver, pancreas and kidneys morphologic structure in adult and pubertal rats. Materials and Methods: Wistar albino male rats of two age categories (young animals of 21 days age (50-70g) and adults (160-180g)) were divided into 4 groups (8 animals in each): 1 - Control 1 (intact young rats); 2 - Control 2 (intact adult rats); 3 - MS3 (young rats with MS) and 4 - MS4 (adult rats with MS). The metabolic syndrome model was induced by full replacement of drinking water with 20% fructose solution (200g/l). After 60 days of MS modeling, determination of rat hematological and serum biochemical parameters, glucose tolerance, blood pressure, liver rates of lipid peroxydation and chromatin DNA fragmentation, as well as morphological macroscopic and microscopic studies were carried out. Results: In pubertal rats, glucose tolerance, hypertension, blood clotting disturbances, DNAfragmentation and lipid peroxydation rates were affected more profoundly, while mature rats showed greater Pseudo Pelger-Huet anomaly development, serum cholesterol and lipoproteins increases, liver and kidney morphology changes. Conclusions: Our current data combined with previous results of other authors allow us to conclude that an animal model (Wistar rats) of MS is quite easily obtained in a full age range, from juvenile to mature rats.
