Megjegyzések:	Background: Renal replacement therapy may have a favorable effect on diastolic left ventricular function, but it isnot clear whether hemodiafiltration is superior to hemodialysis in this field. Nitric oxide (NO) and asymmetric dimethylarginine (ADMA) may play a role in the changes of intracardiac hemodynamics, but it is not clear whether the different renal replacement methods have disparate influence on the metabolism of these materials.Methods: Thirty patients on renal replacement therapy were investigated. First, data was analyzed while patientsreceived hemodiafiltration over a period of three months. Then, the same patients were evaluated during treatmentwith hemodialysis for at least another three months. Echocardiography was performed before and after renalreplacement therapy.Results: No significant difference was found in the volume removals between hemodialysis and hemodiafiltration.The left atrial diameter and transmitral flow velocities (E/A) decreased significantly only during hemodiafiltration. A positive correlation was observed between the left atrial diameter and E/Ea representing the left ventricular pressure load during hemodiafiltration. Significant correlations between NO and A and E/A were observed only in the case of hemodiafiltration.Conclusion: Hemodiafiltration has a beneficial effect on echocardiographic markers representing left ventriculardiastolic function. This could be attributed to the differences between the dynamics of volume removal and itsdistribution among liquid compartments.

Cím:	Cardioprotective Effects of Sour Cherry Seed Extract (SCSE) on the Hypercholesterolemic Rabbit Heart / Bela Juhasz, Attila Kertész, Jozsef Balla, Gyorgy Balla, Zoltán Szabo, Mariann Bombicz, Daniel Priksz, Rudolf Gesztelyi, Balazs Varga, David D. Haines, Arpad Tosaki

Megjegyzések:	Hypothesis. The present study evaluates the hypothesis that sour cherry seed extract (SCSE) protects against cardiovascular disease and inflammation in hypercholesterolemic rabbits, and that this protection correlates with SCSE-induced activity of heme oxygenase-1 (HO-1), a cytoprotective enzyme contributing to oxidative stress responses. Methods: 18 New Zealand white rabbits were divided into three groups receiving: I. cholesterol-free rabbit chow; II. chow containing 2% cholesterol; or III. 2% cholesterol plus SCSE for 16 weeks. Heart functions were monitored by echocardiography 0, 4, and 16 weeks after the initiation of cholesterol-supplemented feeding. At the 16-week time-point, isolated hearts were subjected to ischemia-reperfusion (I/R), followed by measurement of heart rate (HR), aortic flow (AF), coronary flow (CF), aortic pressure (AoP), and left ventricular developed pressure (LVDP). Myocardial infarct size was determined using triphenyl tetrazolium chloride (TTC). Quantification of fatty streaks was assessed using Sudan-III staining. Western blot analysis was used to determine the content of cytochrome c oxidase III (COX III), vascular endothelial growth factor (VEGF), and HO-1 in the myocardium. Results: Relative to cholesterol-treated animals not receiving SCSE, SCSE-treated animals exhibited significantly improved cardiac function and improved peak early diastolic velocity to peak atrial velocity ratio (E'/A'), along with decreased the atherosclerotic plaque formation and infarct size. Increased HO-1 and COX III protein expression and COX activity were also noted in hearts from SCSE-treated rabbits. Conclusions: This study demonstrates SCSE cardioprotective effects on hypercholesterolemic hearts. Correlation of these outcomes with HO-1 expression suggests that the effect may be mediated by activity of this enzyme. However, definitive proof of HO-1 dependence requires further investigation.
