    Background. Metabolic syndrome (MS) is a complex of disorders characterized by abdominal obesity, insulin resistance and glucose tolerance, arterial hypertension, and all types of metabolic disorders. Taking into account the wide range of symptoms accompanying MS, the use of preparations with pleiotropic effects on metabolic processes in the body could be promising for its treatment. Objective. The aim of this study is comparative estimation of metformin or its combination with vitamins' complex or liposomal preparation treatment effects on DNA, RNA, histones, ATP, ADP, AMP contents, and DNA fragmentation processes in testes of rats with MS induced in juvenile age. Methods. MS model was induced by full replacement of drinking water with 10% fructose solution in Wistar male rats of 21–23 days age (50–70 g). DNA, RNA, histones, ATP, ADP, AMP contents, and DNA fragmentation processes investigations were carried out after 60 days of MS modeling and metformin or its combination with vitamins' complex or liposomal preparation treatment. Results. In experiments with pubertal rats with MS and metformin or its combination vitamins' complex or liposomal preparation treatment, we established partially corrective effects of these medications for DNA, RNA, histones, ATP, ADP, AMP contents, and DNA fragmentation processes changes caused by MS development. Conclusions. A comparative analysis of the studied preparations' effects under MS simulation in the juvenile age showed that none of these drugs was able to completely normalize the disorders in studied indicators caused by MS. However, both combinations of metformin with vitamins' complex or liposomal preparation were still more effective in these negative changes' correction then metformin itself. Metformin with vitamins' complex caused a more pronounced influence on the processes of DNA fragmentation, the levels of adenyl nucleotides, and the energy charge of rat testicular cells, while the corrective effect of metformin with liposomal preparation was more noticeable with respect to the content of chromatin components.
