U námi vyselektovaného experimentálního modelu metabolického syndromu X (resistence k insulinu, dyslipidemie, hypertense), u geneticky hypertriglyceridemických krys, bude analisována kausalita těchto poruch a sledovány možnosti intervence.

Two inbred rat strains, differing in their resistance to the induction of myocardial lesions by the administration of isoprenaline (ISO), have been developed. The extent of ISO-induced myocardial lesions (IML) was three to five times lower in the ISO-resistant (IR) strain as compared to that in the ISO-sensitive (IS) strain. The two strains differ also in a number of other genetically determined features, e.g., a higher myocardial glycogen content (MGC) and higher adipose tissue weight in IR rats. Between IML extent and MGC a significant negative correlation has been demonstrated in 2nd filial generation of IR and IS hybrids. By contrast, no correlation has been found between the resistance to the development of IML and the other genetically determined features studied. High resistance to the development of IML and a high MGC were also noted in another inbred strain, the hypertriacylglycerolemic (HTG) rats. Comparison of IML extent in HTG, IR and IS rats has revealed that the extent of IML, while depending on MGC, is independent of triacylglycerolemia. MGC can be raised in IR and IS rats by various interventions (e.g., repeated administration of ISD or fasting). Regardless of the intervention used, it entails a simultaneous increase in resistance to the development of IML. In vivo administration of glucose and insulin, however, exerts only a minimal effect on MGC and on the extent of IML. It may be concluded, therefore, that under our experimental conditions the enhanced resistance to the development of IML, whether genetically determined (IR, HTG rats) or induced by some interventions (fasting, repeated ISO administration), is closely related to an increased MGC.
