It is difficult to explain the discrepancy between the presented results, particularly the lack of the relationship between the concentration profile of both adipocytokines, which appears to contradict the tendencies of their serous concentration described in this paper, where the lowering of the concentration of one adipocytokine (adiponectin), in the course of diabetes, was accompanied by the increase in the concentration of the second one (leptin). This evidence concerns the gene LEP and diabetes mellitus.
